Side panel fasteners shrapnel forming technology and progressive die design
Abstract: This paper describes the possibility of using multi-position progressive die production, analysis of the - side panels fasteners shrapnel multi-position progressive die forming technology and features. Detailed comparison of the parts of several nesting programs and cutting edge design, citing the use of software parts rough commence the calculation of the stamping process and punch strength check process; described in this article Progressive Die from 10-position, is a set of a plurality of processes as one of the mold, the step of forming including punching, forming, bending, etc.; in order to ensure that the mold is of non-interference in the work, should be designed considering; the end of this article a brief introduction of the progressive die material selection and heat treatment and sets out in detail the calculation of the center of pressure.
Key words: progressive mode; nesting; mold design
