设计简介
支板的冲压工艺与模具设计
摘 要
本设计题目为复合模具设计，采用典型倒装复合模具设计。通过工艺分析，工艺方案的确定，确定了模具设计的方向；通过对支板零件尺寸的分析，确定了毛坯尺寸，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专业知识。首先，通过分析制件的结构工艺，去选择模具的类型；然后，分析了制造制件所用的材料进而确定凸凹模的尺寸，也为凸、凹模的材料及压力机选择提供有了依据。最后经过总体分析冲裁件的特征，确定了模具设计参数，选择其他零件及卸料装置。

Support plate stamping process and die desigen
ABSTRACT
The design for the complex subject of mold design, using a typical flip-complex mold design. Through process analysis, process identification program to determine the direction of the mold design; through parts of the support plate size analysis, to determine the rough size, calculating punching power, to calculate the pressure center, select the tonnage presses and presses.
The use of blanking process design and die design expertise. First, by analyzing the parts of the structure of technology, to choose the type of mold; then, analysis of manufacturing parts of the material used to determine the size of convex and concave mold, as well as convex, concave mold and the material selection has been based on press. After blanking the final pieces of the overall analysis of the characteristics of the mold to determine the design parameters, choose the other parts and discharge devices 。
