There are a lot of sheet metal materials suitable for stamping. Sheet metal materials widely used in electronic and electrical industry include:

Black metal plate is easy to be exposed to the air or contaminated with harmful substances and other factors, and gradually occur oxidation and corrosion, resulting in yellow rust spots, damage to the original coating layer. Especially in the process of sheet metal work, after hammering, welding and other processing parts, the original coating protection layer is more likely to be damaged, accelerate corrosion, even if the paint film is sprayed, the paint film will quickly fall off with the base coating. At this time, it is necessary to conduct a thorough coating treatment.

In the production process of auto sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-functional stamping die, only "high-speed" and "multi-functional" can not meet the production requirements, only to achieve continuous to the stamping machine and stamping die conveying plates, and the pressed sheet metal workpiece can be removed from the stamping die in a very short time and transported to the next stamping station, in order to ensure the economic benefits of the theory.

At present, there are some geometric modeling methods for Sheet Metal Parts, such as 2D geometry modeling for sheet metal parts and 3D geometry modeling for auto parts. The former includes coding method, face blending method and interactive dimension input method, and the latter includes bending transformation blending method and voxel blending method. The common disadvantage of all of these styling methods is that when the definition is wrong, it can be very cumbersome to modify and may even require re-entry.

Automobile sheet metal parts are widely used in mechanical and electrical, light industry, automobile and other industries. In the past, the traditional production methods, due to the disadvantages of long cycle, low efficiency, poor quality and so on, have become increasingly unsuitable for modern design requirements. In order to overcome these disadvantages, people have developed some advanced CAD systems, such as parametric technolo G company's prosheetmal, integraph company flatpatternand nesting, etc., these special sheet metal parts design systems, although very powerful, but because most of them run on workstations, both software and hardware are very expensive, therefore, the development of sheet metal parts on Microcomputers CAD system is very meaningful.

Precision stamping, abbreviated as precision stamping, is a cutting-edge forming technology in today's stamping process. In a single stamping process, parts with high dimensional accuracy and good roughness of shear surface can be obtained, and they have certain three-dimensional shape (using composite forming technology). It has the characteristics of high quality, high efficiency, low consumption and wide application.

Precision stamping die is an important equipment needed for stamping process, which is related to the quality of precision stamping parts. Therefore, there are high requirements for the manufacturing of precision stamping die. In order to ensure the manufacturing quality of precision stamping die and reduce the production cost, the materials for manufacturing precision stamping die should have the following process properties:

Metal stamping parts are the mechanical foundation parts with a large amount of use, which are used in almost all industries. Roll plating process is generally used in the production of electroplated metal stamping parts. Hot dip galvanizing (or hot-dip galvanizing for short) is a method to dip the plated metal stamping parts into liquid metal zinc or its alloy with low melting point for coating.

The application of fine blanking technology for precision automobile stamping parts in some factories with simple shape, partial fine blanking, small size and small output, and no special fine blanking equipment can also obtain good technical and economic benefits, it has a good future.

Automotive stamping parts, as the name implies, is composed of automotive parts of the metal stamping parts. In automobile stamping parts, some of them become automobile parts directly after stamping, and some of them become automobile parts after stamping by welding, or mechanical processing, or paint and other processes. There are many kinds of automobile stamping parts, such as car shock absorber stamping parts spring tray, spring seat, spring bracket, end cover, sealing cover, compression valve cover, compression valve cover, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, supporting ear, bracket, etc. are all automotive stamping parts.

For automotive stamping parts, because they are website products and keywords, so in terms of learning requirements, they should be comprehensive and specific. Therefore, the knowledge content and related difficult problems are involved, and none of them can be omitted. So, based on this, we will start to do it immediately to improve your learning efficiency.

The automatic stamping production line mainly includes: progressive die stamping, multi station stamping and series stamping. Because of their own characteristics, they are used to produce different automobile sheet metal parts. With their own unique advantages, they play a huge role in automobile automation and efficient production system. Based on the comparison and analysis of the characteristics of the three stamping automatic production lines, the selection mode of the production line is explained. Therefore, it is convenient for enterprises to select automatic production line according to their own characteristics.

Many car owners think that the body parts still need to be painted with the same color as the original car, so they will ignore the painting process of the body parts when choosing the body parts, which is irrelevant, but this idea is not correct. In order to prevent oxidation and corrosion, the body parts need to be painted before leaving the factory. Indeed, the painting link after replacing the body parts can not only color them, but also protect and prevent oxidation. However, if it is a small factory body parts, the painting treatment during production has uneven adsorption and foaming, which will affect the effect of post painting In the process of using, it is easy to fall off, lead to corrosion, affect and damage the quality of sheet metal parts.

Automobile sheet metal parts is a processing method of automobile maintenance, also called cold work. Say directly, if the exterior of the car body is damaged or deformed, the process of sheet metal is needed to restore the original appearance. The basic tool is a hammer. Hammers with different shapes are padded with iron blocks at the back of the sheet metal parts, which are hammered repeatedly to form. Appearance restorers are also used when necessary.

The production of automobile sheet metal parts mainly depends on dies. In the whole cycle of design, manufacture and commissioning of model design mould, mould design, manufacture and commissioning takes about 2 / 3 of the time, which becomes the main factor restricting the transformation of automobile. This is because sheet metal stamping process is a very complex plastic forming process, many factors directly or indirectly affect the forming results.

Sheet metal parts are thin and easy to form, which can be formed into parts of various shapes. With the application of welding, assembly, riveting and other processes, it is possible to realize multi structure products. At the same time, these characteristics also make sheet metal parts in the process of processing will more or less occur different degrees of deformation, such as bending deformation, torsion deformation, concave convex deformation and so on. These deformations make the size or shape of the whole component change, resulting in quality problems. However, the production process of sheet metal parts has its own rules. For the same type of products, according to the existing equipment, manpower, etc., the sequence of processing can be flexibly adjusted to give a reasonable processing process. So choosing the right process route is an effective measure to prevent and solve this kind of problem.

Hardware refers to the general term of five kinds of metal materials, namely gold, silver, copper, iron and tin. Hardware is the mother of industry and the foundation of national defense. The products produced by hardware materials are generally divided into two categories: big hardware and small hardware.

Sheet metal processing is not only a technical work, but also an important technology that sheet metal technicians need to master. Whether sheet metal products are formed depends on this process. The general processes of sheet metal machining are: metal cutting, cutting tools cut off redundant metal layers from metal materials or workpieces, so as to obtain machining methods with certain shape, size accuracy and surface roughness. Grinding, broaching, turning, milling, planing and drilling are to deform metal, punch, cold roll, cold draw, extrude, bend and, of course, corresponding hot working, so that when metal is formed, work hardening can be used to improve the hardness and strength of parts, but the plasticity will be reduced.

Metal stamping is a kind of technology that uses punch and die to deform or fracture iron, aluminum, copper and other plates and dissimilar materials to achieve a certain shape and size. Metal stamping is sometimes called sheet forming, but it is slightly different. The so-called plate forming refers to the use of plates, thin-walled tubes, thin profiles, etc. as raw materials.

The sheet metal parts of automobile generally refer to the metal shell of automobile, which is usually made of steel plate. On the basis of ensuring certain strength, it is the basic requirement to reduce the weight as much as possible. In addition to the role of protection and beauty, automobile sheet metal parts are also the main carrier of automobile gas resistance. Therefore, the quality and service life of automobile sheet metal parts not only affect the appearance of automobile, but also increase the resistance of air to automobile parts due to the quality and deformation, so as to reduce its economy.
