垫板冲压模具设计
摘要:本设计为一垫板的冷冲压模具设计,根据设计零件的尺寸、材料、批量生产等要求,首先分析零件的工艺性,确定冲裁工艺方案及模具结构方案,然后通过工艺设计计算,确定排样和裁板,计算冲压力和压力中心,初选压力机,计算凸、凹模刃口尺寸和公差,最后设计选用零、部件,对压力机进行校核,绘制模具总装草图,,主要对凸模、凹模、凸凹模、定位零件、卸料与出件装置、模架、冲压设备、紧固件等进行了设计,对于部分零部件选用的是标准件,就没深入设计,并且在结构设计的同时,对部分零部件进行了加工工艺分析,最终才完成这篇毕业设计.

Abstract: The design for a plate of cold stamping die design, according to the size of the ponents, materials, mass production, etc., the first part of the process of analysis to determine the blanking process planning and die structure of the program, and then through the process design calculations, determine the nesting and cutting board, calculate the pressure and pressure washed centers, primary presses, computing convex and concave Die Cutting Edge dimensions and tolerances, the final design selection of parts ponents, to press for checking, drawing die assembly drawings, as well as Mold processing technology of the main parts to the preparation procedures. In which the structural design, primarily to the punch and die, punch and die, positioning parts, unloading and out of pieces of equipment, mold, pressing equipment, fasteners, etc. has been designed, for the selection of ponents are standard parts , there is no in-depth design, and structural design, while some parts for the processing process analysis and ultimately plete this graduation project.
Key words: mold; stamping parts; punch; die; punch and die;
1 前言
冲压是利用安装在冲压设备(主要是压力机)上的模具对材料施加压力,使其产生分离或塑性变形,从而获得所需零件(俗称冲压或冲压件),且主要采用板料来加工成所需零件,,隶属于材料成型工程.
冲压所使用的模具称为冲压模具,(金属或非金属),没有符合要求的冲模,批量冲压生产就难以进行;没有先进的冲模,、冲压设备和冲压材料构成冲压加工的三要素,只有它们相互结合才能得出冲压件
.与机械加工及塑性加工的其它方法相比,.
(1) 冲压加工的生产效率高,且操作方便,易于实现机械化与自动化.
(2)冲压时由于模具保证了冲压件的尺寸与形状精度,且一般不破坏冲压件的表面质量,而模具的寿命一般较长,所以冲压的质量稳定,互换性好,具有
