Causes of faults in progressive die stamping:
1. Edge wear;
2. The gap is too large, and the knife edge effect is not obvious after reaching the destination;
3, cutting edge cutting, unreasonable gap, deviation or release and dislocation.
Method to improve the stability of progressive die: lighter windshield
Level to a mold material, and the strength of the structure of progressive die, progressive die stamping materials, stable performance, progressive die wave characteristics of the thickness of the material in the process of progressive die stamping, because each kind of pressing plate has its own chemical composition, mechanical properties and stamping is closely related to the performance characteristic value, stamping material performance is not stable, stamping material thickness variation, and the change of the stamping materials, not only directly affect the precision of the stamping process and quality, and could lead to damage of progressive die.
In the process of stamping technology and progressive die design, it is necessary to consider the size of tensile resistance, according to the blank holder force to decorate the range of tensile reinforcement and determine the form of tensile reinforcement, so that each area can complete the form deformation mode and deformation degree according to the need.
Notice for design of progressive die: protective seal of lighter
From the viewpoint of design system of progressive die, it is necessary to attach great importance to practical experience to determine the structure of progressive die from the large system of forming stamping and die manufacturing.In this paper, a practical mould scheme is established, and the existing mould manufacturing and stamping production conditions are considered.
Progressive die structure complex, difficult to design, high manufacturing cost, long cycle, so the design should adhere to science, rigorous, pragmatic, careful analysis and detailed planning, make a reasonable design, convenient production and meet the requirements, fully understand the product parts processing and mold manufacturing requirements and use conditions.
