摘要:本设计为自行车脚蹬内板冲孔、翻边、落料级进模设计。冲压模具的工作原理主要是根据零件的外形及工艺要求选用合适的凸模和凹模将板料分离或成形而得到所需制件。因为模具主要用于工件的大批量生产,而且模具需要保证冲压产品的尺寸精度和产品质量,所以要考虑模具的设计能否满足工件的工艺性,能否加工出合格的零件,以及后来的维修和存放是否合理等。本次设计中不仅要确保设计的模具做出的零件能满足工作要求、模具要有足够的使用寿命,还要考虑到它的实际工作环境和必须完成的设计任务。根据一系列的分析、设计、查表、计算,最终确定模具的模架采用对角型模架,凸模凹模采用分别加工法,这样可以采用线切割等数控设备来一次完成全部的工序加工。卸料方式采用弹性卸料,排样方式采用有废料斜排的方式以及采用级进冲压。

Abstract:This is a bicycle pedal plate punching flange, blanking Progressive die mould design. The principle of punching mould is to choose the suitable mould to separate sheet metal to get parts needed according to the shape of the parts and technological requirements . Because the mould major to produce a lot of parts , and mould need to ensure the precision and quality of products, so the design and manufacture of the mould need to consider the mould design could meet with the technology of the design, can work out qualified parts, and maintenance and storage whether reasonable, etc. This design not only need to make sure that the parts can meet the job requirements, to make sure it have enough service life, to consider its actual work environment and design task must pleted. According to a series of analysis, designing, watch checking, calculation, and finally determined that the mode of the mould frame with diagonal type formwork, the punch concave die processing method was used respectively ,so can the linear incision and other numerical control equipment to plete all of the way using elastic and discharging Layout means uses the waste inclined row of style and the stamping means uses level into stamping.
