Abstract：
|
|
The author ingeniously makes it possible that the four work procedures of extruding hole,trimming,blanking and forward extrusion of hollow workpiece are completed on the same set of die whose construction is not complex. Moreover, the procedures have been successfully carried out on a 400kN punching machine, making the productivity of progressive extruding the aluminum sealed sheet reach each minute 60 pieces. Therefore,the productivity has improved significantly. In addition, the article introduces a new no\|scrap bridge technique in blanking operation,which reduces the loss of material and increases the utilization rate of aluminium sealed sheet greatly.
