What are the requirements and control principles for the quality of automotive stamping parts?

Automobile stamping parts indicate that since the stamping parts have become larger and more complex, the quality requirements of stamping parts have become more and more strict. In order to achieve these goals, automobile stamping parts manufacturers have put forward relevant quality control principles, which are reflected in the precision , precision and finesse.

In order to meet the precision principle of stamping parts, the number of processes of drawing parts needs to be determined by drawing process calculation, because it is not only related to material properties, drawing height, number of drawing steps and other factors, but also involves drawing diameter , material thickness and other conditions.

The second is the fine principle of stamping parts. The number of processes as a bending part mainly depends on the complexity of its structure and shape, so it needs to be comprehensively considered according to factors such as the number of bending angles, relative positions and bending directions.

Since the requirements of precision and precision have been met, the principle of delicacy cannot be ignored. When the cross-sectional quality and dimensional accuracy of stamping parts are required to be high, it can be considered to add a trimming process after the blanking process, or directly use precision blanking. process, so as to obtain exquisite stamping parts.

When making stamping parts with simple shapes, it can be done with a single-process die. However, when punching workpieces with complex shapes, due to the limited structure or strength of the die, the inner and outer contours should be punched into several parts. Multiple metal stamping processes, if necessary, can also use continuous die.

In order to ensure the quality of precision metal stamping parts and improve the stability of the process, it is common to increase the number of processes, such as additional positioning process hole punching for bending parts, increasing deformation in the forming process to reduce hole punching to transfer the deformation area, etc. , which can indeed help to improve the quality of stamping parts.
