  In customized sheet metal, the selection of materials is very flexible, but attention should also be paid to the quality of materials, so as to better control the processing quality of materials. If the cold rolled sheet is selected for processing, the processing cost can be reduced, the forming rate can be improved, and the material thickness is more reasonable. When the hot rolled plate is selected for processing, the cost control can be more reasonable, but the forming rate will be relatively low in the product processing process. Sheet metal processing can also ensure the processing accuracy, so where the requirements for product processing accuracy are high, the processing quality of products can be more reasonable, the thickness and specification of products can better meet the actual needs, and the processing quality of products can be effectively improved. These are the main advantages of selecting this process and the benefits of production. Customized sheet metal CNC technology is used in sheet metal processing to better processing operation and better processing effect. So today, in this regard, let us understand, let us deepen in the scope of sheet metal processing. It is mainly used for bending and stretching of sheet metal. The processing sequence of bending is mainly from inside to outside, from small to large, and the bending of special cases to general shapes is preferred. The general process of ordinary sheet metal processing is very simple, but sometimes it is difficult to do. In order to achieve a high quality of sheet metal products, you can't just talk about it without doing it. It requires a lot of operation and understanding of the sheet metal platform.

The stamping production efficiency is high, and the utilization rate of materials is high, so the cost of products produced is low. Zesi Hardware Co., Ltd. is very powerful for stamping processing. Small factories can not achieve this. Our company has 16 years of experience in the hardware processing industry. Shenzhen Puffitt Precision Products Co., Ltd. tells you some tips: the processing process of precision metal stamping parts includes: blanking → punching → trimming → grooving → flanging (bending) → blanking. In order to stabilize the product quality and improve the production efficiency, the factory now uses automatic manipulators to input more actions under the complete materials and products. The work is simple and repetitive. The machine can operate 24 hours without interruption at a stable speed. It replaces the problem of traditional manual labor, which belongs to the benefits of scientific and technological progress and gradually liberates manual labor. Processing of precision metal stamping parts Customized processing of stamping parts and drawing parts can customize various complex metal stamping parts and drawing parts according to customer requirements, and the compound die only needs one station. In a stamping stroke, the die can realize two or more stamping processes at the same time. They are only conducive to ensuring that the mold process reaches or improves the mold efficiency, including guide rails, fasteners, specification parts, etc. It should be pointed out that not all molds must have the above six parts, especially single process molds, but working parts and necessary fixed parts are necessary. There are many reasons for the deformation of stamping during processing, such as materials, required part shapes, processing and production conditions, etc. For example, aluminum alloy raw materials have large thermal expansion coefficient and are easy to deform. Deformation during thin wall machining. So how to effectively improve it must be encountered and handled in the actual production activities.  

  Stamping accessories are also a type of stamping processing. Stamping processing uses the power of conventional or special stamping equipment to make the sheet metal deform directly under the deformation force in the die. Stamping processing is to use the power of conventional or special stamping equipment to make the sheet metal deform directly by the deformation force in the die. Stamping machine is the person who operates the stamping equipment to deform and separate the workpiece. At present, the stamping processing factory will not only produce various products in batches, but also customize products according to different requirements of customers. As long as customers require customization of the size, application requirements and other information of stamping parts, the information factory can customize and produce in batches. Stamping accessories Is it tiring to be a stamping worker? What is difficult to do? Can we start? Wait a minute, these are the problems that people who want to work in the stamping factory encounter. Now let's understand what seals do! It is usually a combination of multiple processes applied to an artifact. Stamping, bending, shearing, stretching, bulging, spinning and correction are the main stamping processes. When dozens or hundreds of stamping parts are produced every minute, the processes of feeding, stamping, discharging and waste materials are completed in a short time, and accidents such as personnel, equipment and quality occur from time to time. Therefore, stamping safety production is a very important issue.  

Before the precision metal stamping parts are processed and drawn, the blank of the metal stamping parts shall be wiped clean to avoid that the surface or material surface is not clean when the mold is working, which may mix with dust and other debris, damage the surface of the metal stamping parts, and affect the product quality. When stamping the structural shape of parts, it is recommended to use simple and reasonable surfaces and their combinations, such as planar, cylindrical and helical surfaces, while minimizing the number and area of machined surfaces. Stamping usually does not produce chips and waste materials, consumes less materials, and does not need other heating equipment, so it is a material saving and energy-saving processing method, and the cost of producing stamping parts is low. Stamping parts are highly efficient, easy to operate, and easy to realize mechanization and automation. As stamping depends on stamping dies and stamping equipment to complete processing, the number of strokes of ordinary presses can reach tens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. Each stamping stroke can obtain a stamping part, so the production of metal stamping parts can achieve efficient batch production. Processing of precision metal stamping parts The processing cost of stamping increases with the improvement of precision, especially in the case of high precision. The requirements for quality standards of stamping parts are getting higher and higher. The main difficulty of the current stamping process is precision stamping or full bright band. All stamping parts need blanking to meet the required specifications and styles. The blanking process will lead to burrs in the cutting part of the workpiece, collapse angle on the surface, insufficient brightness, and even local fracture. Therefore, we should attach great importance to such a situation, otherwise it will cause great problems.  

The processing of sheet metal shell is an indispensable part of computer hardware equipment, which is often seen in our daily life. Sheet metal shell, central console monitoring station, box type substation shell, etc. When selecting a sheet metal case processing manufacturer, the corresponding manufacturer should be found according to their own needs. The quality of chassis and cabinet sheet metal products is perfect. Now the production equipment of the enterprise has entered the advanced digital level, and the product management of the enterprise has also been greatly improved. High machining accuracy and appearance. Electronic box products are ideal boxes for high-end instruments and meters, mainly used for loading instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other items. The performance parameters of welding equipment are highly required. Sheet metal chassis The texture of metal surface shall not be damaged during welding. During the surface pretreatment of the chassis and cabinet, the surface can be sprayed or painted, so that we can choose appropriate methods according to different specific situations to increase the service life and service life of the sheet metal chassis and cabinet. The enclosure of chassis and cabinet is made of metal plate. All components are made of stainless steel rolled plates. During assembly, attention must be paid to the inspection and acceptance of machined chassis. Sheet metal processing For the production of sheet metal parts, raw materials are expected to directly (or blanks) change the shape, size, performance and processed products. It is an important part of the production process. Blank casting, forging, welding, heat treatment parts change and edit material properties and processes.

For parts with complex punching shape and limited die structure or strength, the internal and external contour of stamping accessories shall be divided into several parts for punching. The shape and size of sheet metal materials are expansion stampings, introduced by Zesi Hardware Co., Ltd., which is the premise for analyzing the deformation degree of stampings, designing processes and formulating process procedures. Through the combination of these two methods, Zesi Hardware solved the initial shape and size of sheet metal stamping parts, which not only has high calculation accuracy, but also consumes less time. Electronic components, auto parts and decorative materials. Stamping accessories Because stamping parts generally refer to cold stamping parts, this process is required in electronic devices, auto parts and decorative materials. Stamping parts refer to the forming and processing method of workpieces with required shape and size by applying external force on plates, strips, pipes and profiles by presses and dies to cause plastic deformation or separation. And the hardware can be used alone or as an auxiliary device. From a professional point of view, the stamping process is to separate raw materials and sheet metal according to a certain shape through stamping dies and stamping equipment, and plastic deformation of metal to obtain the required shape. For specific dies, the shape, size and performance of stamping parts are basically consistent. To put it simply, the stamping die is the "template" used for stamping. One template can only punch one type of stamping parts. Different types of stamping dies need to be selected according to different sizes, materials and shapes of stamping parts.

For small sheet metal processing factories, they can handle ordinary and simple products, but they have no choice but to produce customized or slightly difficult sheet metal processing. At this time, it fully reflects the processing strength of sheet metal. The sheet metal processing industry should not only rely on price to please customers, but also strictly control product quality and improve service level, so that enterprises can go further and further. Many different kinds of energy can be used for welding, including gas flame, an arc, laser, electronic beam, friction and ultrasound. Customers should also know about the hardware industry when customizing sheet metal. Some novices who are not very clear about the hardware industry may not understand that well, which will mislead them into thinking that customizing sheet metal is simply hardware processing. In fact, it is not. Although the hardware industry has grown rapidly, the precision hardware processing industry is still very strict. There are many processes for sheet metal processing in the hardware industry. Customized sheet metal The surface treatment of sheet metal processing plants usually includes electroplating, spraying, anodizing, etc. The sheet metal processing factory provides customers with a variety of stainless steel sheet metal processing accessories. With the development of the times, people have higher requirements for the appearance of sheet metal processing products. In addition to meeting the functions, they also pay more attention to adapt to various environments, so the appearance processing of stainless steel sheet metal processing is very important.  

Many people know CNC machining and understand the meaning of cnc machining. But they do not know what aluminum alloy cnc machining means. In fact, aluminum alloy cnc machining is a method of using digital information to control the movement of the machine tool and the machining process. The machine tool that uses CNC technology to implement processing control, or the machine tool that is equipped with CNC system is called CNC (NC) machine tool. 1, aluminum alloy shell CNC machining electroplated tin - cobalt alloy Electroplated tin-cobalt alloy is closer to the tone of electroplated cobalt, but softer and more popular. At present, most foreign countries are used to replace chromium. Electroplated cobalt is not easy for barrel plating, while electroplated tin-cobalt alloy can be used for barrel plating of small parts. In addition, the electroplated tin-cobalt alloy has excellent uniform plating ability and barrel plating ability, so it can be applied to complex-shaped workpieces. If double layer of nickel is plated on the base layer, the corrosion resistance is no less than that of chromium plating. To prevent surface discoloration, it should be treated with chromate impregnation, which also improves its corrosion resistance. It has the appearance of light rose hue, which makes it very good and has excellent corrosion resistance. If a tin-nickel alloy plating is applied to a lustrous substrate or on top of a bright nickel plating, a good lustrous surface can be obtained. If plating is applied on a non-glossy surface (pear pattern), the original condition of that surface can appear. The uniform plating ability of the plating layer is excellent, and there is almost no leveling effect at all, so it is suitable for the plating of products requiring very fine lines and rotary processing. 2、Aluminum alloy CNC processing plating copper-tin alloy The color of low tin bronze plating of aluminum alloy shell is pink or golden yellow, fine crystallization, it has high anti-corrosion ability and good polishing performance, often used as a protective-decorative nickel base layer, used in light industry, handicraft industry, mechanical instrument industry and other industries. Medium tin bronze plating has a golden color and good corrosion resistance. It is mainly used as a decorative chrome plating base layer. The hardness and stability in air of aluminum alloy processing is higher than that of low tin bronze plating. However, due to the high tin content of the plating, the base layer used as a protective decorative plating tends to bloom after the chromium set, which is the weakness of the medium tin bronze plating. High tin bronze plating has a beautiful silver-white luster and good polishing performance, high hardness and wear resistance, and is used in industrial design instead of silver or chromium as a protective and decorative surface plating for reflective instruments, instruments, daily commodities, etc.

  What will the application of precision parts machining in the aviation industry be like? As follows! With the rapid development of the aviation industry, the semi-finished products of industrial aluminum profiles put forward higher and higher requirements, especially for high-speed military and civilian aircraft require the use of more perfect semi-finished products, in order to make the structure of each component more reasonable, to ensure a lighter structural quality, strength and rigidity, while significantly reducing the number of components, reducing the cost of group paddle, jointing and maintenance, etc.. Ensure perfect and beautiful surface (good sealing, no seams, no deformation, etc.). (1) Large industrial aluminum profiles belong to the particularly important structural parts on the aircraft, requiring the profiles to have excellent mechanical properties. Therefore, aluminum profiles must be produced by customizing industrial aluminum alloy profiles using hard aluminum or super hard aluminum alloy to extrude. (2) Since industrial aluminum profiles are used as structural parts of key parts of the aircraft, good overall performance and uniform organization are required, especially for the finished products and very strict requirements. And extrusion after quenching products in the coarse crystal ring defects is very difficult to avoid, but also the world's extrusion workers for decades with little success Minde aluminum 868 profile specific gravity table one of the research topics. (3) for the cross flower beam and comb joint plate and other aluminum profiles, on the one hand, its large cross-sectional area, often makes the extrusion deformation coefficient is relatively small, while on the other hand, its lateral and high to must withstand a large load, and thus require its lateral and high up to have a very high mechanical properties. This contradiction is often an important reason for the scrapping of aluminum profiles.

Computerized gongs are a kind of artificial intelligence, which is controlled by the computer to complete the complex processing of the machine tool. The most complex part of the computer gong is the control system, the computer sends various instructions to control the machine three axes of the servo motor in accordance with the development of the route to collaborate with each other to process a variety of complex processes, while ensuring a high degree of processing accuracy. The body part, the main components are castings, castings are also a major reason affecting the accuracy of the computer gong machine tool. It can even be said that the castings are good or bad to determine the grade of the machine and the stability of future use. What are the requirements for the manufacture of castings, is to not deform, enough rigidity. Not deformed refers to the actual processing after the factory, the machine accuracy to maintain good, deformation will affect the accuracy. Rigid enough machine to meet the heavy chip processing needs of the work. Foreign casting manufacturing than the domestic and much more mature, to Taiwan, for example, Taiwan, such as Yongjin, Dali these machine castings to be done after aging treatment, some placed in the sea for several years after the immersion of seawater, after the natural wind and rain, the performance of the castings tend to stabilize, and then taken out of processing, so that the stability of the machine tool made naturally to good. CNC milling machine is an automatic processing equipment developed on the basis of the general milling machine, the two processing technology is basically the same, the structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with tool magazine is also called machining center. CNC lathe, turning center, is a high-precision, high-efficiency automatic machine tool. Equipped with multi-station turret or power turret, the machine tool has a wide range of plus process performance, can process linear cylindrical, diagonal cylindrical, circular arc and a variety of threads, grooves, worm gears and other complex workpieces, with linear interpolation, circular arc interpolation of various compensation functions, and in the mass production of complex parts to play a good economic effect.
