Raw material performance of high-precision stamping parts: There are 4 points about raw material performance testing, 1. Chemical analysis, mainly to analyze the content of chemical elements in raw materials, to confirm whether it can meet the performance of the product; 2. Material inspection, material appearance, thickness , quality certificate, etc. meet the procurement requirements; 3. Hardness testing, generally using Rockwell hardness tester and other equipment to test the hardness of materials; 4. Forming performance testing, for products that need to be bent, annealing process is added during production, and the material is subjected to annealing. Bending test, cupping test, etc.;

Talking about the steering system of the car chassis
Everyone drives every day, manipulating the steering wheel of the car can make the car drive at the angle you need. Very little research is done on how the steering wheel of the car makes the wheel turn. A series of devices used to change or maintain the driving or backward direction of the car are called Automotive steering system software.

What are the technical requirements for modern automotive stamping parts?
The technical requirements of modern automotive stamping parts are developing in the direction of complex structure, increased block size, more components on related sides, increased bearing capacity and strict internal stress restrictions. This requires and promotes the development of special stamping forming technologies such as hydroforming, precision forming, explosive forming, spin forming, dieless forming, laser forming and electromagnetic forming.

Do you know what scrapers are commonly used in automotive sheet metal parts?
In the process of car maintenance, after the exterior has been knocked and welded by sheet metal workers, the painter must also fill it with putty and smooth it. The commonly used tools for filling putty are hard scrapers and soft scrapers.

How to effectively control the quality of automobile stamping parts?
Hardware automobile stamping parts are becoming more and more precise, with more and more varieties, and the market scale is constantly expanding. As the quality and precision requirements of various industries are getting higher and higher, how to ensure the quality has become a key factor. There are many reasons for the poor stamping parts, the selection of stamping materials, the operation during the stamping process, and the clamping of station equipment Unloading, etc. may also damage the stamping parts. Therefore, details should be fully considered in each link of the entire manufacturing process to avoid quality problems as much as possible.
