|
Based on design features and technical requirements of top head,by analyzing stamping process plans,the blanking-drawing-punching-curling compound die which could complete synchronously four procedures of blanking,drawing,punching and curling in the same working station was designed reasonably.The die working process and main design points were introduced detailedly.The technology problems of the position of sheet metal,guiding,stripping,pushing and the optimization of die structure were resolved.After the actual production,it was found that this die greatly improved the production efficiency and the shape and the size of top head were ensured by the reasonable die structure.The economic efficiency of company was increased.
