Brass welding pieces punchingblankingprogressive die design
[Abstract] Cold stamping mould in mould occupies an important position, product scope affected big, accounts for about half of the total number of mould, so by every aspect highly, and stamping quality stand or fall depends greatly on and mold design and manufacturing technology level. This design requirement of stamping materials for H62, and the thickness of 1 mm, mass production, involving blanking, punching, so using progressive die is very suitable. Design of progressive die using elastic and unloading, and block material, guide pin, guide set with guidance, through the punching the punch, blanking the punch and dies, the joint action, complete blunt system process. The slide block within the trip, complete all stamping requirements, thus greatly improve the efficiency. Stamping mould design process of:
1. The process analysis process calculation, inner-space value choice, to determine the design process and die structure.
2 at the same time the design of mold respectively were analyzed and explained.
3. To press a reasonable choice.
4. The whole process using AutoCAD software rendering mould 2d drawings and individual detail drawings.
