It is basically known that the precision of precision hardware parts processing is the main thing. If you want to have a good precision, you must first prepare for the stability of the process before production. Stability is divided into two main aspects: process stability and production stability. Process stability is to ensure the quality of precision hardware parts processing products, and production stability is mainly to ensure the production capacity of technical personnel.
In the processing of precision hardware parts, in addition to the need to do a good job in two aspects, such as process stability and production stability, but also need to do a variety of processing problems, because not only these two reasons affect all. In addition to this, the factors affecting its stability can be summarized as the following aspects.
1. The selection of stamping die materials and the strength design of the structural parts of the die are directly related to the stability of the forming parts themselves;
2, the performance of the stamping material, the volatility of the thickness, the variation range of the material and other factors, have a certain impact on the quality of the parts themselves and the stability of the stamping die;
3. The size of tensile bar resistance and the variation range of blank holder force play an important role in the quality stability of precision hardware parts in the process of deep drawing.
4. Whether the selection of lubricant is reasonable or not directly affects the stability of parts processing and the service life of punching die.
In order to ensure the stability of precision hardware parts processing, in the mold material selection and structure design, stamping material selection, including lubricant selection and other aspects, in the design of precision hardware parts processing technology and stamping die design, have to be taken into account in advance, to ensure the smooth stamping production.
