首先，对锁扣做全面的研究。研究的内容有：结构的分析、所达到的精度、工序的安排是否合理等。设计比较合适的排样方式，可以做到降低成本的效果；然后进行模具设计整体的工艺计算和分析，选用合理的方案。工艺分析和计算的内容包括合理的方案的选择和工序的安排组合，根据材料来计算模具所使用的冲压力，从而选择合适的压力机。模具刃口的选择和计算，选择和是的凸凹模间隙可以提高模具的寿命；而且只有刃口的精度保证了，我们工件的精度才能保证。
最后，根据我们计算出地凸凹模刃口尺寸数据和模具设计过程中的结构，尽量选用合适的标准件，做到标准化，从而完成装配图以及主要零件的设计。最后在进行确定和校核模具高度，选择合适的标准模架，进行压力机校核，以满足实际生产的需要。

Abstract
This design is for intermediate frequency slag ladle stamping die design, through the analysis of the workpiece, found a blanking, drawing, punching the three basic processes, need to design a progressive die for the production. For design of mould design simple, the use of our knowledge, we can be the knowledge in a system of learning and mastering, achieve knowledge.
First, make a comprehensive study of compressor. The content of the research are: analysis of the structure, achieved accuracy, such as the arrangement of the process is reasonable. More appropriate way of layout design, can reduce the cost of effect; And die design of the whole process calculation and analysis, choose the reasonable scheme. Process analysis and calculationincludes the selection and reasonable process scheme of arrangement, to calculate the impactpressure using the mold according to the material, so as to choose the right machine.Selection and calculation of cutting edge, and is the clearance between punch and die cangreatly improve the service life of die; and only precision blade ensures precision parts, we can guarantee.
Finally, according to our calculate convex concave die cutting edge dimension data and structure in the process of mold design, choose the right standard parts, as far as possible to achieve the standardization, so as to complete assembly drawing and main parts design. Finally in the determination and highly dies, choosing the appropriate standard mould frame, press check, so as to meet the needs of actual production.
Key words：progressive die, stamping process, mold design .
