How to improve the stability of automobile stamping die?

No matter where the stamping parts are used, the manufacturing principle is the same, which depends on the action of press and die to make the material plastic deformation or separation, and finally obtain the desired shape and size of the workpiece. It seems that the whole process is not complicated, but if we do not grasp it well, there will be error problems, so we should try our best to overcome these problems.

In the production process of automobile stamping parts, because the die core is a complex surface, if the guide surface is machined after the casting is formed, it is easy to cause the gap error after the sliding matching between the processing surface and the guide surface of the die. This problem will have a serious impact, not only the normal use of the mold will be hindered, but also directly affect the forming quality of stamping parts, and bring security risks.

Therefore, we hope that similar problems will not arise again. In addition, if the special guide plate is not used in the guide part, but is replaced by the processing surface mutual guide structure, the gap will be too large, and the manufactured stamping parts will have defects that can not be adjusted, which will affect its quality.

Stamping parts must have stamping die to produce, and in the production of stamping die, a series of unstable factors must be eliminated, in order to make the final workpiece meet the required requirements.

The stability of automobile stamping die mainly includes two aspects, one is the stability of technology, the other is put forward for the production process. It is not easy to ensure the stability of these two aspects. First of all, we need to know which factors will make the die unstable, including material, structure, process, specification and so on.

Then adjust and control all aspects, from the selection of mold materials to the design of structure and size; And then to the implementation of the process, and even the types of lubricants used can not be underestimated. Taking the selection of die material as an example, in addition to high strength, high wear resistance and other good performance, we should also fully consider the production demand of automobile stamping parts, so as to make the forming of die more stable.
