ABSTRACT
The mold industry is the important base industry each department of national economy develop, possession the precision of production high, the production efficiency is high and produces the periods short and so on the characteristics. Punching die has been widely used in industrial production. Punching die could increase the efficiency of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value. This paper introduces inflectional of punching die and swell of punching die , and mainly ,and it introduces ,die design and process plan of assmebled bracket. And it including: the process of the parts analysis to determine the process plan, design and calculate of the mould, design stamping press and the pressure Center, selected presses, draw part drawing and assembly drawing. Process plan of assmebled bracket including: analysis of part’s shape, select of blank, the main part’s process has selected and analysised. The dies here discussed can be easily made, conveniently used, and safely operated. And it could be used as the reference in the large scale production of similar workpieces.
