设计简介
该工件仅包含落料和冲孔两个基本工序,可以采用以下三种工艺方案:
第一:先落料,后冲孔。采用单工序模生产。
第二:落料—冲孔复合冲压。采用复合模生产。
第三:冲孔—落料级进冲压。采用复合模生产。
方案一:模具结构简单,成本较低,但需要两道工序两副模具,由于两次定位使得工件的形位误差难以保证,尺寸较小,制件的质量较差,成本高而生产效率低,难以满足大批量生产要求,操作也不安全,故不宜采用。
方案二:只需一副模具,由于一次成形,减少了多次定位出现的定位误差,并且在模具结构中采用弹性压料装置,使其制件质量较好,工件的精度及生产效率都较高。
方案三:也只需一副模具,生产效率高,操作较方便,工件精度也能满足要求,但是成本较复合模高。
通过对上述三种方案分析比较,该件的冲压生产采用第二种方案进行冲裁为好。
摘 要
本设计题目为复合模具设计,体现了典型复合模具设计的要求,内容与方向。通过工艺分析,工艺方案的确定,确定了模具设计的方向, 对毛坯尺寸的确定,计算冲裁力,来计算压力中心,选择压力机和压力机的吨位。
本设计运用了冲裁工艺及模具设计的基础知识。首先,分析了板材的性能要求,为选去模具的类型做了准备,同时,也为凸,凹模的材料有了依据。后分析冲裁件的特征,确定了模具设计参数,选择其他零件及卸料装置。也为凸,凹模尺寸的计算有了根据。还有零件的加工工艺。

ABSTRACT
This design topic designs for The piercing die design of the dunnage backup plate, body now typical model The piercing die design of request, contents and direction.Pass the craft analysis, the craft project really settles, making sure the direction of The piercing die design, really settling to the blank product size, computing to the blanking pressure, compute the pressure center, choose the tonnage of the pressure machine and the pressure machine.
This design made use of to hurtle foundation knowledge of blanking craft and The piercing die design. First, Analyzed the function request of the plank material, did preparation for the type that chooses to the die, is also convex, in the meantime, the material of punch and cavitydie had a basis.Analyze to hurtle a characteristic of cut the piece behind, make sure the molding tool design parameter, choose other spare partses and unload to anticipate device.Is also convex, the calculation of the cave mold size had a basis.Still there is spare parts to process a craft.
