When precision metal stamping parts are processed, the dimension accuracy grade and surface roughness grade shall be reduced as much as possible under the condition of ensuring normal use, which is conducive to product exchange, reducing waste products and ensuring the stability of product quality. The designed stampings shall be conducive to the processing of existing equipment, process equipment and process flow as far as possible, and to the extension of the service life of the die. The shape and size of metal stamping expansion sheet is the premise of analyzing the deformation degree of stamping parts, designing process and formulating process procedures. If the shape of the sheet is suitable, it can not only significantly improve the uneven distribution of sheet deformation along the sheet, but also increase the forming limit, reduce the height of the lug and reduce the cutting allowance. Processing of precision metal stamping parts Stamping parts manufacturers can select raw materials for re inspection as required. Chemical analysis and metallographic examination: analyze the content of chemical elements in materials; Determine the particle size level and uniformity of materials; Evaluate the grade of free cementite, banded structure and non-metallic inclusion in materials; Check shrinkage cavity, loose material and other defects. In order to improve the stability of stamping process and ensure the quality of stamping parts, it is sometimes necessary to increase the number of processes; For metal stamping parts with simple shape, single process die is adopted. Due to the limitation of die structure or strength, the upper and lower contours of workpieces with complex blanking shapes should be divided into several parts, and multiple stamping processes should be adopted. If necessary, continuous die can be selected. For metal stampings with high flatness requirements, leveling process can be added after blanking process.

Many customers in our hardware industry need to process cases. Sheet metal processing generally requires the cooperation of tools, and good tools can often get twice the result with half the effort and speed up work efficiency. It must be necessary equipment to process these sheet metal cases. For example, we need to use common sheet metal processing equipment: blanking equipment, forming equipment, welding equipment, lathes, etc. Before the preliminary processing, the customer needs to explain the requirements and design drawings. Sheet metal chassis The application of this technology is of great significance in case processing. Because its success can shorten the production cycle of sheet metal processing, but also can improve the quality of products. The application of molds will also reduce the processing accuracy and affect the quality of our products. The laser technology can help us to achieve better processing without increasing the production cost, and the product quality will also be improved steadily. According to the requirements of customers, the protective film is plated on the surface of sheet metal to increase the adhesion of lacquerware, that is, through automatic laser cutting machine baking, the sheet metal processing process can get greater step change and realize unmanned operation, thus saving labor costs, greatly improving production efficiency and increasing production quantity, which plays an important role in the future development of sheet metal. In order to ensure the quality of sheet metal processing, sheet metal processing plants need to control the distance between convex edges and the limit size of the distance between convex edges. The key selection of the certificate should follow the process standard. Problems found during chassis processing shall be consolidated and maintained in time. The machine should go through parts of things together to consolidate the screws one by one. Sheet metal processing technology includes cutting, stamping and bending, welding, surface treatment, assembly, and various machines will be used in this process.

We often talk about customized sheet metal processing products. First, design drawings are required before customization, and then sheet metal processing enters the second process, namely, forming, which mainly includes stretching and bending, in which corresponding stretching and bending dies are required. Generally, the drawing is carried out on an ordinary punch and a CNC punch. The bending process can only be completed on the bending machine or CNC bending machine. Efficient and high-quality sheet metal is what customers need. What we need to do is to go out and consider customers' ideas. The quality of stamping raw materials will determine the quality characteristics, service time and cost of the goods. We must be clear about the material selection regulations and standards of automotive stamping parts when customizing, so as to get a good finished product. Customized sheet metal The welding of sheet metal products plays an important role in arc welding and gas cutting. Arc welding is flexible and controllable, and can be widely used in various fields. All mechanical equipment is simple, with good wear resistance and low maintenance cost. However, the labor productivity is high and the quality is not stable enough. Management decisions depend on the level of workers. In the production process of sheet metal processing manufacturers, according to the different raw materials used for raw materials, the processing level of the products should also be fully considered. The processing center of the application part of the plate is used for production and processing. The realization of many processing technologies is usually used to cut the thickness of the metal plate, and then the production and processing of the products. This enables the sheet metal processing of laser cutting equipment to make full use of laser cutting equipment for professional processing.

As for the processing of sheet metal chassis, you asked us the right question. For the processing of chassis, Zesi Hardware is specialized in processing this convenient chassis and cabinet product. Zesi Hardware has 16 years of industry experience. We will produce according to the product material, specification, thickness and shape on the drawings after confirming the drawings according to your requirements. The panel of the sheet metal case shall be flat without deformation, and the opening of the cabinet door shall be uniform and neat. The quality of boxes varies depending on the level of demand. Sheet metal chassis There are different types of chassis, but no matter how different they are, they all have reasons. The design of sheet metal parts has become a very important link in the process of product development. Mechanical engineers must master the design skills of sheet metal parts, so that the designed sheet metal parts can not only meet the functional and appearance requirements of the product, but also make the stamping die manufacturing simple and low cost. How does the sheet metal processing factory receive sheet metal processing orders? Having your own official website (you can do Baidu promotion bidding, etc., this method is designed to make the purchase find you - follow up normally), and registering stores on well-known platforms (also need to do pay ranking, this method is designed to make the purchase find you - follow up normally). Above is the way to receive sheet metal processing orders.

Precise metal stamping parts processing is the production process of parts with certain shape, size and performance that use the power of conventional or special stamping equipment to make the sheet materials directly subject to deformation force in the mold. The die used for stamping is called stamping die, or simply stamping die. Mold is a special tool for batch processing materials (metal or non-metal) into required parts. Stamping die is very important in stamping. By processing the surface burrs of hardware products, such as a kind of comb produced by us, which is stamping the hardware, the edges and corners of the punched comb are very sharp. We polish the sharp parts of the edges and corners into smooth surfaces. throughput. For example, the speed and quality of proofing, mold design and processing, production efficiency and quality, and the system capability of the entire factory. Processing of precision metal stamping parts In order to improve stamping deformation and part quality, materials should have the characteristics of good plasticity, small bending ratio, large plate thickness orientation coefficient, small plate plane orientation coefficient, and small ratio of yield strength to elastic modulus. For the separation process, the material does not need to have good plasticity, but it needs to have a certain degree of plasticity. The better the plasticity, the more difficult the material is to be separated.

If you want to become a master of CNC machining center operation, you must stand the experience of time and constantly improve your working ability. In the CNC machining industry, CNC machining center programming should be compiled according to the operating characteristics of the machine tool, which is conducive to observation, inspection, measurement, safety, etc. For example, for the same kind of parts, the same processing content, in the vertical processing, and horizontal processing, respectively processing, the program must be different.   CNC machined parts Proficient in operating CNC machine tools. It takes 1-2 years of study, and the operation is sensitive. Beginners, especially college students, know how to do it, but they just don't listen. In this process, learn: system operation mode, fixture installation, part datum alignment, tool setting, zero point offset setting, tool length compensation, radius compensation setting, tool and handle loading and unloading, tool grinding, part measurement (be able to skillfully use vernier caliper, micrometer card, dial indicator, dial indicator, inner diameter lever gauge), etc. What can reflect the level of an operator is: horizontal processing, and processing of large gantry (moving beam, top beam). Must have good fixture foundation and measurement technology level. It is difficult to analyze the causes of fixture only qualitatively, but not quantitatively. In the process of CNC processing in Shanghai, there is a method called thread milling. What is it specifically? Suzhou CNC machining factory adopts thread milling cutter, three-axis linkage of machining center, that is, arc interpolation of X and Y axes, and linear feed of Z axis for thread milling. Thread milling is mainly used for machining large hole threads and threaded holes of difficult to machine materials. It has the following characteristics: ⑴ Fast processing speed, high efficiency and high processing precision. The cutting tool is generally made of cemented carbide, with fast cutting speed. The manufacturing precision of the cutter is high, so the milling thread precision is high. ⑵ The milling cutter has a wide application range. As long as the thread pitch is the same, a tool can be used for both * * threads and right-hand threads, which is conducive to reducing the cost of the tool. (3) Milling is easy for chip removal and cooling, and the cutting condition is better than that of tap. It is especially suitable for thread processing of difficult to machine materials such as aluminum, copper and stainless steel, It is especially suitable for the thread processing of large parts and valuable materials, and can ensure the quality of thread processing and the safety of workpieces. (4) Since there is no tool front end guide, it is applicable to machining blind holes with short thread bottom holes and holes without undercut.

In the process of processing, there will always be some trouble-free problems that we did not expect, but no matter what problems we encounter, we should solve them in time, and the oil leakage is also a relatively common problem. If it is an accessory, the maintenance is very simple. If it is a cylinder then it is very troublesome and can seriously lead to machine scrapping. So below we will learn what causes oil leakage in cnc machining center? 1, oil change does not meet the requirements. Often also cause cnc machining center oil leakage. Oil change in the problem is mainly manifested in three aspects. One, for the use of high-viscosity lubricant parts, oil change arbitrarily changed to low-viscosity lubricant, it will make the corresponding box, shaft holes and other sealing performance is affected to a certain extent, and sometimes will greatly reduce the sealing of these parts. Secondly, when changing oil without cleaning the oil tank, the dirt in the oil tank may enter the lubrication system, blocking the oil path, wear the seals causing oil leakage. Third, too much oil when changing the oil, especially in the parts of the rotating parts, due to the churning effect of rotating parts, more likely to overflow phenomenon. 2, the lubrication system parts of the selection and adjustment is not appropriate and cause oil leakage. For example, cnc machining maintenance personnel maintenance selected too high pressure or too much oil out of the oil pump, or adjust the system pressure, relief valve, safety valve, pressure reducing valve and other pressure adjustment is too high, cnc machine tool lubrication system flow is too large, etc. and return system and sealing system does not match, it will cause oil leakage. In fact, causing cnc machining center oil leakage is not just the above points, if we encounter similar problems in the operation must do a good job of checking, find the cause in time to avoid unnecessary losses. In the machining center back after the purchase of a good comprehensive inspection to see if there are casting defects or parts damage problems, such as timely contact with the manufacturer. The operator should also pay attention to the following points when using the cnc machining center to process the workpiece.   (1) For the first trial cutting process of cnc machining, single-stage operation mode should be used for machining. (2) When the automatic operation of CNC milling machine starts, the fast multiplier and feed multiplier S are in the lowest gear, and then the efficiency is increased after cutting into the workpiece. (3) In the operation of CNC milling machine machining program, it is necessary to pay attention to the coordinate display of CNC system. (4) It is forbidden to touch the CNC milling machine tools and chips with your hands. The chip must be cleaned with a brush.

CNC precision parts processing in the industry is still relatively wide, why would say so, in fact, we can see in life, the role of obvious, in some mechanical equipment above the application will also be more, to know the CNC precision parts processing of precision machining requirements are also high, why, because the customer in the requirements of quality, and this CNC precision parts processing itself is a big advantage, so we have to do better, more customer trust, which is what CNC precision parts processing needs to do. 1, CNC lathe milling plane class parts of the feed path Milling flat parts outside the general, usually use the side edge of the end mill for cutting. In order to reduce the traces of the cutter, to ensure the quality of the appearance of the parts, the cutter cut-in and cut-out procedures need to be carefully designed. When milling the outer surface, the entry and exit points of the milling cutter should be along the extension line of the general curve of the part to cut into and out of the exterior of the part, and should not be cut directly into the part along the normal direction, in order to avoid scratches on the machined surface and to ensure the general lubrication of the part. Milling off the internal general appearance, if the internal general curve promises to extend, it should be cut into and cut out along the tangent direction. If the internal general curve does not allow the extension, the tool can only cut in and out along the normal direction of the internal general curve, and will be cut, cut out point selected in the intersection of the two elements of the part general. When the internal elements tangent no intersection, in order to avoid the tool to avoid the notch left at the corner of the generalization when the tool is withdrawn tool cut-in and cut-out points should be far from the corner. Shown is the tool path when milling the outer whole circle by circular interpolation method. When the whole circle processing is finished, do not 2 retreat at the tangent point, but should let the tool move more along the tangent direction for a distance, to avoid the withdrawal of the tool complement, CNC lathe tool and workpiece appearance touch, constitute the workpiece scrap. When milling the inner arc, we should also follow the guideline of cutting from the tangential direction, and best organize the processing road from the arc transition to the arc, which can improve the processing accuracy and processing quality of the inner hole appearance.

This point is certainly very important, because if the operator has an operation error, then it will certainly affect the quality of the product, so some details above the problem is very important, then we will understand the following parts processing operators must know a few common knowledge points what? 1, to ensure stable and reliable cutting performance of tools Tool cutting performance and life to be stable and reliable, with CNC machine tools for processing, the tool to implement a regular mandatory tool change or by the control system for tool life management, the same batch of CNC cutting tool cutting performance and tool shall not have a large difference, to avoid frequent downtime to replace the knife or cause a large number of scrap processing workpiece. 2, to ensure a long tool life Tool should have a high life, should be selected cutting performance, high wear resistance of coated tools and a reasonable choice of cutting amount. 3、Avoid tool loss Ensure reliable chip breaking, chip rolling and chip removal, disorderly chip system will bring great harm to the automated production, causing tool chipping, resulting in various factors of different degrees of wear and tear. 4、Ensure the tool state changeover Ensure that the tool can be quickly transposed, blade replacement and automatic tool change and other operations. 5、Scientific and reasonable adjustment of the tool state Can quickly and accurately adjust the tool to the processing size of the part, the original positioning point of the tool, etc. 6, according to the characteristics of CNC selection of tools Must start from the CNC machining characteristics, custom CNC tool standardization, serialization and universal structure system, so that you can quickly buy the right tool. 7, the establishment of database and management system Should establish a complete database and management system, CNC tool types, more complex management, both automatic identification of all tools, memory of its specifications size, deposited in the location, has been cutting time and remaining life, followed by the replacement of tools, delivery, tool size pre-tuning and other management. 8、Prepare a perfect tool information system Have a perfect tool assembly, familiar with the machine tool pre-conditioning, code marking and identification system. 9, always monitor the status of the tool Set up an online monitoring system for tool wear and breakage...

In practical application, any kind of product is processed and inspected in various series before it can be arranged for sale and use in the outside world. According to the data, precision machining is the processing of finished products inside the most number of work of an item. After all, with excellent performance of machinery and equipment can produce better quality products. With the development of the modern industry, the structure and configuration of machinery has become a focus, only the technology continues to improve upward, the future development of various industries to have greater play. Precision machining is the process of changing the size or performance of a workpiece by a mechanical device. The difference in processing methods can be divided into cutting and pressure machining. Mechanical parts are composed of a number of surfaces, the study of the relative relationship between the surface of the parts, must determine a benchmark, the benchmark is used to determine the location of other points, lines, surfaces based on the points, lines, surfaces on the parts. According to the different functions of the benchmark, the benchmark can be divided into two categories: design benchmark and process benchmark. Precision machining design benchmark is used to determine the location of other points, lines and surfaces on the part diagram, called the design benchmark. Precision machining process benchmark is the benchmark used in the process of processing and assembly of parts, called the process benchmark. Process benchmark according to the different uses are divided into assembly benchmark, measurement benchmark and positioning benchmark. A, assembly benchmark: assembly to determine the position of the part in the component or product benchmark, known as the assembly benchmark. Second, the measurement benchmark: to check the size and position of the machined surface benchmark, known as the measurement benchmark. Third, the positioning datum: the datum used to position the workpiece during processing, known as the positioning datum. As the positioning reference surface (or line, point), in the first process can only choose the unprocessed rough surface, this positioning surface is called the rough benchmark. In each subsequent process can be used in the machined surface as a positioning reference, this positioning surface is called the fine reference.
