Abstract [资料来源:http://doc163.com]
The topic of this design is the center bowl stamps forming handicraft and design for die.The requirement,content and direction of the design of the stamps forming plate parts are embodied on this stamping die design. The designer’s foundation knowledge of the stamping die design is reinforced and is able to design more complex stamping die through the design.
This design the elementary knowledge which designs using the stamping formation craft and the die, first has analyzed the work piece formed craft and the die forming structure to the workpiece quality influence. Introduced the center bowl filling piece stamping die design when must pay attention to the main point, through carries on the craft analysis to the workpiece, may determine the workpiece the formed processing uses set of superposable dies and a punching die. Embarks from the control workpiece size precision, counter center bowl filling piece stamping die each main dimension has carried on the theoretical calculation, by determined each work components the size, designs from the die to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on each important components using CAD the design.
