Introduction to Basic Knowledge of Stamping Parts

TIME：2017-11-04

Stamping parts are sometimes referred to as sheet metal forming, but with slight differences. The development of stamping parts has directly driven the development of the stamping parts processing industry. The so-called sheet metal forming refers to the forming method of plastic processing using sheet metal, thin-walled tubes, thin materials, etc. as raw materials, collectively known as sheet metal forming. At this time, the deformation in the direction of thick plates is generally not given much consideration.

The stamping industry is a wide-ranging industry that delves into all aspects of manufacturing, and is referred to as sheet metal forming. There is also such a term in our country. Stamping in China is sometimes referred to as sheet metal forming, but with slight differences. The so-called sheet metal forming refers to the forming method of plastic processing using sheet metal, thin-walled tubes, thin materials, etc. as raw materials, collectively known as sheet metal forming. At this time, the deformation in the direction of thick plates is generally not given much consideration.

The vigorous development of stamping should be attributed to the development of automobiles, airplanes, and daily necessities.

Stamping application:

(1) Stamping in the automotive industry. Mainly focused on deep drawing. In our country, this part is mainly concentrated in large factories such as automobile factories, tractor factories, and aircraft manufacturing factories, and independent large-scale stamping and deep drawing factories are not yet common.

(2) Stamping of automotive and other industry components. Mainly for punching and shearing forming. Many of these enterprises are classified under standard parts factories, as well as some independent stamping factories. Currently, there are many small factories around some automobile or tractor factories.

(3) Electrical component stamping factory. This type of factory is a new industry that has developed with the development of electrical appliances, and is mainly concentrated in the south.

(4) Daily necessities stamping factory. Make some handicrafts, tableware, etc. These factories have also seen significant development in recent years.

(5) Stamping factory for household appliance components. These factories only emerged after the development of my electrical appliances industry, and most of them are distributed within home appliance companies.

(6) Special stamping enterprises. Stamping for aviation components belongs to this category of enterprises, but these process factories are also classified under some large factories.

At present, there are few large enterprises engaged in stamping in China, and if there are, there are also some small factories. The main feature is the parts or component factory. This is the main characteristic of the stamping industry. Different from other raw material manufacturing plants.

The market and technological level of stamping in China:

Due to the fact that many stamping factories belong to the host factory, the stamping parts market is not very sound. But the market for small stamping parts is very mature in some southern regions. From the current situation, there are the following problems in China's stamping parts market:

(1) Some production capacity is oversupplied, and some stamping factories in the main engine plant cannot be put away or held. For most of the year, there is a shortage of production tasks and no market behavior.

(2) The market competition in the home appliance and stamping parts industry is fierce. But there are not many competitive enterprises that have become successful.

(3) No one is conducting a serious study on the stamping parts market. The stamping parts market is chaotic and disorganized.

In the above-mentioned market conditions, technological development is limited and the entire industry lags behind, manifested in:

(1) The overall level is low, with overcapacity and a lack of technology in many industries. Technological progress is slow.

(2) The material technology, mold technology, lubrication technology, and equipment level are all at a relatively low level, far from meeting the needs of domestic production development.

Challenges faced by the stamping industry:

(1) The development of automobiles, airplanes, and the increasing demand for environmental protection have put pressure on stamping. The intensive production, personalized development, energy-saving requirements, and environmental protection requirements of products will promote a new round of technological innovation and transformation in the stamping industry.

(2) The development and application of simulation technology is a means for the development of stamping.

(3) Automation and flexibility requirements are factors considered in the development of stamping.

(4) The application of composite materials will drive the advancement of stamping.

(5) The emergence of new technologies has driven industry progress, and these new technologies are:

A、 Composite material forming process;

B、 Stamping technology for laser welded slabs of various thicknesses;

C、 Internal high-pressure tube expansion technology;

D、 Light alloy forming technology;

E、 Digital molding technology.

Characteristics of stamping technology development:

(1) Highlight "; Refined, economical, and clean;

(2) Stamping Forming Plus; Digitization, digitalization, and controllability;
