The main uses of stamping products are widespread, such as electronic furniture, machinery manufacturing, home improvement industry, automobile manufacturing, etc.! So what are the rules for stamping parts commonly used in the automobile manufacturing industry? Take a look below;

Under the environment of the structure of the parts of the design plan, the automobile stamping parts should be selected with simple and useful structures, and the number of surface layers and the total processing area should be as small as possible;

The materials commonly used in automobile stamping parts should not only reach the technical specifications of the designed product, but also should reach the processing delineation of the processing technology such as drilling, electroplating and cleaning after stamping;

Delineation of the forming performance of automobile stamping parts; in order to better benefit the stamping deformation and the promotion of stamping parts, the material should have lofty constructability, and the ratio of the yield strength of the material to the ductile mold is smaller. For the separated process, It is not necessary that the material has good plastic deformation. The better the plastic deformation, the less easily separated it is;

The stamping oil used in the whole process of automotive stamping parts processing should conform to the processing technology, and the special stamping oil with good performance can improve the processing natural environment and promote the precision of the parts;

Ordinary automobile stamping parts use plates, thick-walled tubes, thin aluminum profiles, etc. as raw materials to develop stamping, and use high-speed punches and die shells to deform or break stainless steel plates, iron, aluminum, copper and other materials of the opposite sex. It is a kind of processing technology with inevitable appearance and specifications. Auto stamping parts processing, auto parts stamping, etc. Automobile stamping parts processing is a contemporary enterprise mainly engaged in the manufacture and sale of automobile stamping parts and sheet metal processing.

Blanking and punching Blanking and punching are processes that separate the blanks. The process of blanking and punching is completely the same, but the purpose is different. When blanking, the separated side is the finished product, and the remaining periphery is waste; the punching is to obtain the hole, the punched sheet is the finished product, and the separated side is the waste. Blanking and punching are collectively referred to as blanking. Both the punch and the die of the blanking die have sharp cutting edges, and there is a gap between the punch and the die that matches the thickness of 5-10 to ensure that the cut is clean and less burrs.

  • (1) The designed stamping parts must meet the product application and technical performance, and be easy to assemble and repair.
  • (2) The designed stamping parts must be beneficial to improve the utilization rate of metal materials, reduce the types and specifications of materials, and reduce the cost of materials as much as possible. Accept low-cost materials in an allowable environment, and make the parts as waste-free and waste-less as possible.

Lianxinfa has many years of experience in automotive stamping parts processing manufacturers. Some pre-sales and after-sales teams meet the different needs of customers. Customers who need automotive stamping parts processing manufacturers can call to ask for the price, and we will have someone to sponsor you to inquire.

Studies have shown that magnesium alloy is a metal with high specific strength, good rigidity, and strong electromagnetic interface protection performance. Its application prospects in electronics, automobiles and other industries are very promising, and it has a tendency to replace traditional ferroalloys, aluminum alloys, and even plastic materials. .

In the metal stamping process, because each stamping sheet has its own chemical composition, mechanical properties, and characteristic values ​​that are cordially related to stamping performance, the performance of stamping materials is unstable, the thickness of stamping materials is bumpy, and the stamping material changes, Not only will it simply affect the precision and character of the metal stamping process, but it may also cause damage to the mold.

Take stretch ribs as an example, it occupies a very tight position in metal stamping. In the process of stretch forming, the forming requirements of the product have a certain amount of pulling force that is properly distributed along the fixed periphery. This pulling force comes from the advantage of the stamping equipment, the deformation resistance of the one-sided material at the edge, and the movement resistance on the blank holder surface . And the occurrence of movement resistance, if only the benefit of the blank holder force, the conflict force between the mold and the material is not enough.

For this reason, it is necessary to configure a stretch rib that can generate greater resistance on the blank holder to increase the resistance of the feed, so that the material undergoes greater plastic deformation to meet the requirements of plastic deformation and plastic activity of the material. At the same time, by changing the size and distribution of the resistance of the stretched ribs, and mastering the rate of movement of the material into the mold and the amount of feed, the effective adjustment of the tensile force and its distribution in each deformation zone of the stretched part is realized, so as to prevent stretching Questions about the quality of the product such as chipping, wrinkling, and deformation during molding. It can be seen from the above that in the process of setting the stamping process and mold design, the tensile resistance must be considered, and the tensile ribs should be arranged according to the change of the blank holder force and the form of the tensile ribs, so that each deformation area is as required Deformation method and degree of deformation realize forming.

In order to inquire about the stability of automotive stamping parts processing molds, it is necessary to strictly check the following aspects:

  • ①In the process setting stage, through the analysis of the product, the possible shortcomings of the product in the manufacturing can be predicted, so as to formulate a stable manufacturing process plan;
  • ②Implement the standardization of manufacturing process and manufacturing process;
  • ③Establish a database, and continue to summarize and optimize it; analyze the application system with the help of CAE, and get a very optimized management plan.

We produce quality CNC machined parts, sheet metal fabrication, metal stamping prototypes and production, wire forming parts,deep drawn enclosures and related metal parts. We are committed to provide custom-made metal stamping parts at high quality and lowest cost.Under current economy situation, most customer are persuing cost-effective items.
