Precautions for designing progressive die for precision stamping parts 'Hardware'

Causes of failure during the stamping process of the precision stamping progressive die: 1. Edge wear; 2. The gap is too large, and the effect of the knife edge after reaching the destination is not obvious; 3. The cutting edge is cutting, unreasonable gap, offset or loose Detachment and dislocation. Methods to improve the stability of the progressive die of precision stamping parts: level to the strength of a mold material, progressive die structure, stable performance of the stamping material of the progressive die, wave characteristics, the thickness of the progressive die material in the process of stamping the progressive die, Because each pressing plate has its own chemical composition, mechanical properties and stamping performance characteristic values u200bu200bare closely related, the performance of stamping materials is unstable, the thickness of stamping materials fluctuates, and the changes of stamping materials not only directly affect the accuracy and quality of the stamping process, And may cause damage to the progressive die. The stamping technology and progressive die design process must consider the size of the tensile resistance, decorate the range of the tensile steel bars and determine the form of the tensile steel bars according to the blank holder force, so that each area can complete the forming deformation mode and degree of deformation according to the needs. Precautions for designing progressive die for precision stamping parts: From the perspective of progressive die design system, from the determination of the large-scale system that constitutes stamping and die manufacturing and the structure of the progressive die of parts, the role of practical experience should be highly valued. Realistic, establish a practical mold plan, while considering the existing mold manufacturing, stamping production conditions. The progressive die structure is complex, difficult to design, high manufacturing cost, and long cycle. Therefore, the design should adhere to scientific, rigorous, pragmatic, careful analysis and detailed planning, make a reasonable design, facilitate production and meet requirements, and fully understand the processing and processing of product parts. Mold manufacturing requirements and conditions of use. If you want to know more about the precision stamping parts industry, welcome to consult: (same number on WeChat)
