侧双圆孔U形弯曲件的冲压成形工艺及模具设计【落料冲孔复合模、弯曲模】
摘要
本设计题目为侧双圆孔U形弯曲件复合模具设计，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
The design title is the design of compound die for U shaped bending partswith side double round holes,which embodies the requirements, content and direction of typical compound die design. Through process analysis and process plan determination, the direction of die design is determined, the blank size is determined, the punching force is calculated, the pressure center is calculated, and the tonnage of press and press is selected.
This design uses the basic knowledge of blanking process and die design. First, the performance requirements of the plate are analyzed, and the type of die selection is prepared. At the same time, the material for convex and concave die is also provided. After analyzing the characteristics of the blanking parts, the design parameters of the die are determined, and the other parts and unloading devices are selected. Also for convex, the calculation of the die size is based. There is also the processing technology of the parts.
Keywords: compound die, punch, die
