垫片冲压模具设计 摘 要 冲压是在室温下，利用安装在压力机上的模具对材料施加压力，使其产生分离和塑性变形，从而获得所需零件的加工方法。本文将重点讲述冲压模具的设计方法和计算过程。 首先，本文将讲述冲压工艺方案的确定和模具的结构形式，并画出排样图和计算材料的利用率。 其次，本文将讲述凸凹模设计尺寸的计算，冲裁力和压力中心的计算，以及压力机的选用。 最后，本文将讲述模座，模架，导柱和导架的选用，以及凸凹模的加工方法，画出装配图。 关键 冲压; 凸模; 凹模; 模架 Punch forming technology and die design Author : WangXiaopeng Tutor : JiangAiyun Abstract Stamping is in room temperature, the use of mold on the pressure in installation of material pressure, so as to produce separation and plastic deformation, and will obtain the needed parts processing method. This paper focuses on the stamping die design method and calculation process. First of all, this article will talk about the determination of stamping process program and die structure form and draw the layout figure and calculation material utilization. Secondly, the paper will be about the size of the punch mold design calculation, cutting force and the calculation of the pressure center, and the selection of the press. Finally, this article will talk about mould seat, formwork, guide pin and the selection of guide tube, and die and punch processing method, draw the assembly drawing.
