How about the design principle and application range of automotive hardware stamping parts?
2020-09-15 11:04:19

Metal automobile stamping parts refers to the use of dies for non-ferrous metal plates such as steel and other non-ferrous metals at room temperature, which are formed to the specified shape by the pressure required for processing by the press. So, what is the application range of metal stamping parts?


Automotive stamping parts


(1) Stamping in the automotive industry. Drawing is the main method. In our country, this part is mainly concentrated in automobile factories, tractor factories, aircraft manufacturers and other large factories.

(2) Automobile parts stamping. It is mainly formed by punching and shearing. Many of the enterprises in this sector are owned by standard parts factories, and there are also some independent stamping plants. At present, there are many small factories near some automobile factories or tractor factories.

(3) Electrical parts stamping plant. This kind of factory is a new industry, which develops with the development of electrical appliances. The factories in this sector are mainly concentrated in the south.

(4) Daily necessities stamping factory. Some handicrafts, tableware and so on, these factories also have the big development in recent years.

(5) Stamping plant for household electrical parts. These factories were established after the development of household appliances in China, and most of them are distributed in household appliance enterprises.

(6) Special stamping enterprises. For example, the stamping of aviation parts belongs to this kind of enterprise, but these process factories are also included in some large factories.

Design principles of metal stamping parts:

(1) the designed metal stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

(2) the designed metal stamping parts must be conducive to improving the utilization rate of metal materials, reducing the varieties and specifications of materials, and reducing the consumption of materials as far as possible. If allowed, low-cost materials should be used to make the parts as much as possible to achieve no waste and less waste blanking.

(3) the design of metal stamping parts must be simple in shape and reasonable in structure, so as to simplify the die structure and simplify the number of working procedures, that is, to complete the processing of the whole part with less and simple stamping process, reduce the use of other processing methods, and be conducive to stamping operation, facilitate the organization of mechanized and automated production, and improve labor productivity.

(4) under the condition of normal use, the designed metal stamping parts should have lower requirements for dimensional accuracy grade and surface roughness level as far as possible, which is conducive to product exchange, reduce waste products and ensure product quality stability.

(5) the design of metal stamping parts should be conducive to the use of existing equipment, process equipment and process flow to process them, and to extend the service life of the die.
