Do you know the difficulties in automobile stamping parts?

　　The understanding of stamping parts may not be familiar with and understood from now. There is still a lack of this aspect, so there is a need for understanding.

Stamping parts, the specific definition of the word, is through the mold and press equipment, exerting forces on the raw materials, thus to produce plastic deformation or separation, so as to obtain the desired shape and size, this kind of work, it is called auto stamping parts. And stamping, it is its forming process. The blanks of punching are usually hot rolled or cold rolled steel plates, steel strips, etc.

Stamping parts, the general can be divided into two kinds of hot stamping parts and cold stamping parts. The surface state and precision of hot stamping parts are not as good as cold stamping parts, but better than castings and forgings, and their cutting processing is less.

Question 1: the structure and precision of the mold, the manufacturing cost and the service life, which will affect the parts of the stamping parts?

The structure and accuracy of the die will affect the forming and accuracy of the stamping parts, and the manufacturing cost and life will affect the cost and quality of the stamping parts.

Question two: what are the general punching equipment?

There are many kinds of punching equipment. Generally speaking, if the plate is punched, then the hydraulic press will be used. However, for ordinary general stamping, it is carried out by mechanical press, etc.

Question three: is it necessary for the product to be lubricated in the cold stamping of the workpiece?

This is certainly needed, and the reason is that the temperature will rise rapidly during the cold stamping process, so it is necessary to lubricate the temperature so as to avoid problems.

The inspection of the stamping parts, the main method, generally speaking, is mainly the following, which is specifically for:

Method 1: touch test

A gauze is used to clean the surface of it, and then the inspector brings a touch glove and touches along the longitudinal direction of the stamping part. It is a fast and effective way, but it needs some experience.

Method two: flexible gauze grinding

With the gauze surface clean, and then use the flexible network to close to the stamping sand surface, and along the longitudinal grinding the whole surface, in order to check whether there is pitting or surface indentation.

Method three: oil coating inspection

First wipe the surface with gauze, and then oil the whole surface to keep the oil in the same direction. After the inspection under strong light, if there is pitting, ripple etc..
