Importance of sheet metal case design

What is the inspection standard for the appearance design of the sheet metal cabinet? Generally speaking, we can distinguish from the following aspects. The appearance design innovation of sheet metal chassis cabinet is also important and difficult. In the face of the increasingly serious market homogenization problem, the differentiation of the appearance design of the sheet metal cabinet is particularly important. The appearance design of sheet metal boxes and cabinets should also be people-oriented, adhere to humanized and perceptual design, think about various problems encountered in the design process from the perspective of users, pay attention to the human-computer interaction design of products, and embody humanistic care in details, so that the products are comfortable, novel and beautiful. Sheet metal chassis Inside the case is a place full of electromagnetic signals of various frequencies. Good electromagnetic shielding is not only good for the work of the computer, but also can not be ignored for human health. In fact, the radiation of the computer is much greater than expected! Different thicknesses can also cause different effects. Generally, a good watch case is made of steel plates more than 1.6mm, while a poor watch case is only 0.6mm. The difference is twice as much! Poor quality boxes can be almost flattened with one hand. It depends on whether the mechanical strength design is a good steel plate. The quality of the chassis is guaranteed. To ensure the bearing capacity of the chassis, a good mechanical strength design is also required. Because of the special properties of sheet metal materials, their appearance design does not give designers too much freedom. Therefore, the cabinet design of sheet metal chassis is not easy.

Differentiation between innovation of sheet metal case and traditional industry

Understand customers' requirements for appearance and size of chassis and cabinet products, as well as the use of products. Different processes shall be selected according to the products of different customers, and precautions shall be specified in the process drawings: for example, the surface of sheet metal parts shall not be scratched. The laser cutting slit is small, and the workpiece will not deform basically - the high power density is achieved by using the beam focusing, so that the material can be rapidly heated to vaporization and evaporation to form a hole. With the relative linear movement of the beam and the material, the continuous formation of the hole slit is very narrow. A good cabinet processing factory and after-sales service are the guarantee for the long-term development of the enterprise. Manufacturers with poor after-sales service find it difficult to continue to cooperate with old customers. The sheet metal case processing is connected by the transmission grounding suspension device to form an electric field between the spray gun and the sheet metal parts. Sheet metal chassis The powder reaches the surface of the sheet metal under the double action of electric field force and compressed air pressure, and forms a uniform coating on the surface of the workpiece through electrostatic attraction. Sheet metal processing: shearing punching folding welding or flame plasma cutting folding welding process. In the face of orders with multiple varieties, small batch, customization, high quality and short delivery time, it shows obvious inadaptability. The laser cutting technology of "shearing and punching" instead of "shearing and punching" has been widely used in the manufacturing of special-shaped (or complex shape) workpieces and samples (single piece or small batch) with its high flexibility and flexibility, gradually replacing some traditional sheet metal processing. The processing materials for precision machining have strict requirements on chemical composition, physical and mechanical properties, chemical properties and processing properties. Only when the texture is uniform, the performance is stable, and there are no macro and micro defects inside and outside, the materials meeting the performance requirements can obtain the expected precision machining effect.

Requirements of precision sheet metal processing companies

When machining sheet metal, it is impossible to have no error at all. But what we need to do is to control this error within the allowable range. Therefore, when cutting materials, it is necessary to ensure that the error of scissors can be controlled. In addition, shear plate and NC machining also play an important role in sheet metal processing. Although the sheet metal processing parts are not large, the processing technology is still quite complex, so more careful operation is required. Therefore, in sheet metal processing, some performance requirements such as fatigue resistance are very high. Before the sheet metal processing company, the staff need to understand that the processing range is in the general operation, they can choose copper, stainless steel, galvanized sheet and other materials to complete the processing process. This processing method has a wide range, and can also meet the production needs of different industries. During the processing process, they can choose materials flexibly, without worrying about the impact of the progress of production tasks due to the materials not meeting the processing requirements. Sheet metal processing company During sheet metal processing, the welding seams of the cabinet body shall be neat and uniform, without cracks, edges, gaps, burns, slag inclusions, pores, welding nodules, pits and other defects. These shortcomings should not be shown on the external surface of the cabinet, and the internal cabinet should not be too obvious. Sheet metal processing enterprises usually need various mechanical equipment to meet different process requirements. The stamping accuracy of sheet metal is generally about 0.1mm, and the bending accuracy can generally reach 0.5mm. Therefore, compared with metal processing, the precision is much lower, but the profit is relatively high. For example, stamping can generally reach about 30%, and laser cutting can reach more than 50%. At present, sheet metal is very profitable.

The role of automobile stamping parts processing

The car body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, electrical appliance iron core silicon steel sheet are all processed by stamping. Instruments, household appliances, bicycles, office machinery, household appliances and other products also have a large number of stamping parts. Mechanical steering system consists of steering control mechanism, steering device and steering transmission mechanism. The invention relates to a forming method for improving the dimensional accuracy of formed parts or obtaining small fillet radii. Automobile stamping parts processing is a process of stamping stainless steel, iron, aluminum, copper and other plates and anisotropic materials with stamping dies to make them deformed or broken, so that they have a certain shape and size. Generally, the stamping process of automobile parts uses sheet metal, thin-walled tubes and thin profiles as raw materials, which has the advantages of mechanization and automation. Automobile stamping parts processing Stamping materials are mainly hot rolled or cold rolled (mainly cold rolled) metal sheet and strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc. Most of the covering parts, such as the body outer panel, some bearings and supporting parts, such as the frame, carriage and other auto parts, are auto stamping parts. The steel used for cold stamping is mainly steel plate and strip, accounting for 72.6% of the steel consumption of the vehicle. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping process, product quality, cost, service life and production organization. Therefore, the reasonable selection of materials is an important and complex work.

Demand for customized sheet metal processing

When customizing the sheet metal, the customer should provide the requirements for sheet metal processing, otherwise it is impossible to start. When you receive the order information and requirements of the goods, you should form a clear idea in your mind, and have a certain understanding of the appearance and molding of the customer's goods. Then, through drawing and drawing, the sheet metal parts are intuitively drawn on the image, and each parameter and scale are indicated. The processed sheet metal parts shall be inspected for quality, the dimensions of the sheet metal parts shall be sampled for inspection, the appearance shall be inspected, the nonconforming products shall be reheated, and the inspection report shall be filled in. Precision sheet metal processing has been greatly improved in terms of material selection, structure design, and processing accuracy improvement. Precision sheet metal is suitable for processing large and small batches of products. It has the characteristics of short processing cycle, high precision and good unity. A netizen submitted a paper and asked: I want to drill holes on the 3MM thick aluminum sheet metal parts, with plastic bearings inside the holes. The requirements for the accuracy of the holes are high, and the position accuracy between each vacancy is high. I don't know how much the machining accuracy and position accuracy of precision sheet metal parts can reach? You are right.

What are the types of precision metal stamping parts?

From the perspective of the hardware industry, stamping parts belong to professional hardware processing with strict processing requirements. Precision metal stamping parts can be directly made into flat parts, or prepared for other stamping processes such as bending, drawing, forming, etc., or cut and trim on formed stamping parts. Blanking is widely used in automobile, household appliances, electronics, instrumentation, machinery, railway, communications, chemical industry, light industry, textile, aerospace and other industrial sectors. The blanking process accounts for 50%~60% of the whole stamping process. Processing of precision metal stamping parts The processing of precision metal stamping parts is mainly divided into two categories: separation process and deformation process. The separation process is a stamping processing method that can separate the stamping parts and sheet materials along the required contour line and obtain a certain section quality; Deformation process is a kind of stamping processing method which can make the blank plastic deformation without damage to obtain the required shape, size and accuracy. There are two kinds of stamping temperature: cold stamping and hot stamping. This depends on the strength, plasticity, thickness, deformation degree and equipment capacity of the material, and the service conditions of the original heat treatment state of the material shall be considered. The simple stamping die is divided into cold stamping and hot stamping. The simple stamping die is a process that only completes the stamping die in one stroke. When working, the strip is fed between two guide plates on the die until it touches the locating pin.

What are the stamping accessories?

Stamping is an advanced manufacturing technology in modern stamping production. It integrates high-speed precision stamping technology, high-precision variable stamping die technology, high-quality product material technology, intelligent control technology and green car body high-tech. The process of stamping parts is to punch the parts with complex shape and limited die structure or strength. Its internal and external contours shall be divided into several parts. For workpieces with high flatness requirements, leveling process can be added after blanking process. The design of stamping parts shall be simple in shape and reasonable in structure, which is conducive to the operation of stamping parts, improving labor productivity, organizing production and mechanization and automation of stamping parts processing. To improve the stability of stamping process, it is necessary to increase the number of stamping processes to ensure the quality of stamping parts. Stamping accessories For example, bending parts are punched with additional positioning process holes, and the forming process increases the deformation and reduces the transfer deformation area of hole punching. As friends in the hardware industry may know, the materials for stamping parts processing are mainly hot or cold rolled (mainly cold rolled) metal plates and strips, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin plates, stainless steel plates, copper and copper alloy plates, aluminum and aluminum alloy plates, etc. If you really want to get a thorough understanding of this industry, it depends on our stamping parts manufacturers. The domestic stamping processing technology is relatively strict, and there are many similar factories, but there are few large factories like Zesi Hardware Co., Ltd. in the industry. That's all for the knowledge of stamping today. See you next time.

Material selection of customized sheet metal?

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 Strength Importance of Precision Hardware Stamping Parts Processing

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.
