双支架锁片落料模设计
[摘要]本篇课题是对双支架锁片落料模的研究，首先对工件的材料、结构以及精度进行分析。材料方面，工件选用Q235做为生产材料。结构方面工件外形简单易懂，厚度为3mm,精度方面，工件没有特殊要求，采用IT14精度等级，通过对双支架锁片分析，工件只有落料、冲孔的工序。本篇仅对落料工序进行介绍说明，综上所述我们可以使用单工序落料摸来对双支架锁片生产。
首先需要对双支架锁片进行分析，从而得出最适合的设计方案，通过双支架锁片的工件图我们可知其有落料工序。对于工件材料的选择，首先要分析材料的通用性、性价比以及材料的精度能否达到对工件的生产。然后确定合适的模具工艺方案，可以从单工序模、复合模和级进模三种方案来进行对比。确定出哪一种最适合生产，通过对比分析，最终采用落料模来对落料工序完成制作。

Design of blanking Die for double support Lock
[Abstract] In this paper,we study the double support locking plate, and analyze the material, structure and precision of theworkpiece. In terms of material, theworkpiece is made of Q235 as the production material. In terms of structure, theworkpiece shape is simple and easy to understand, thickness is 3mm. In terms of precision, theworkpiece has no special requirements. IT14 precision grade is adopted. Through the analysis of double support locking piece, theworkpiece is only used for blanking and punching. This article only introduces and explains the blanking process. In conclusion,we can use the one-step blanking touch to produce double-support locking piece.
First of all, it is necessary to analyze the double support lock, so as to get the most suitable design scheme. Through theworkpiece diagram of the double support lock,we can know that the double support lock has the blanking process. For the selection ofworkpiece materials, first of all, it is necessary to analyze the universality of materials, the ratio of performance to price andwhether the accuracy of materials can achieve the production ofworkpiece. Then the appropriate die process scheme can be compared from three schemes: single sequence die, composite die and progressive die. Determinewhich is the most suitable for production, through comparative analysis, and finally use blanking mold to complete the blanking process
