Abstract:

The mixed layout method based on digital control processing with whole plate was designed. The stock layout parts were connected by “tiny gap connection ”, whose parameters are as follows: width 0.6mm, the spaces between parts are not more than 200mm. The upper plane of the terrace die was in the same plane with the upper plane of retainer plate through changing the height of former terrace die, which solved the collide problem happened in continuous feeding process, realized the continuous punching processes. The process results show that the stock utilization rate increases about 15%, the process time decreases about 30%, and the quality of the stampings is improved by using the method.
