单孔圆垫圈冲压复合模设计878690

工件图

摘要
本设计是对垫圈进冲压复合模设计，通过对制件的材料，结构，尺寸精度分析。本制件选用材料10钢。垫圈总体左右对称，厚度为1.5mm,垫圈上外形直径为22mm，中间有一个直径10mm的通孔。所以垫圈可以采用较简单的复合冲裁模。复合冲裁模采用落料冲孔同时加工，复合冲裁模加工的精度较高且垫圈要求无翘曲无扭曲。所以选择正装落料冲孔复合。本从凹模开始设计，选择模架，设计凸模，再算凸凹模等模具零件尺寸。
首先是对垫圈的工艺分析，再确定工艺方案。然后对零件图的排样设计，计算材料的利用率以及冲裁板料及条料的利用率。再进行各工艺力的计算和冲裁模工作部分的设计计算，再校核压力机，最后对主要零部件的设计与标准件的选择。为本次垫圈的cad绘制和成形提供依据。通过上面的设计方案画出模具各零件图和装配图。
本次设计通过对垫圈的冲压模具设计，加深了我们对所学知识的理解和运用。阐述了模具的设计过程和证明垫圈在实际设计制造中的可行性。

Abstract
The design of this paper is on the M10 washer into the stamping die design, through the parts of the material, structure, size accuracy analysis. Material selection material Q235 steel. M10 washer overall symmetry, thickness of M10, 1mm gasket on the diameter of 21mm, the middle of a diameter of 10mm through the hole. So M10 washer can be used more simple compound punching die. The compound punching die is made of blanking and punching process, the precision of the composite punching die is higher and the M10 gasket is not distorted. So the choice of formal blanking compound. This paper starts from the design, selection of die mold, mould design, and then count the punch mould parts size.
The first is the process analysis of M10 washer, and then determine the process plan. Then the layout design of the part drawing, the utilization ratio of the material and the utilization ratio of punching sheet and strip are calculated. Then, the calculation of the technological force and the design calculation of punching die working parts, and then check the press, the final design of the main parts and the selection of standard parts. Provide the basis for CAD drawing and forming of the M10 gasket. Draw the parts drawing and assembly drawing of the mold through the above design plan.
This design through the M10 gasket stamping die design, deepen our understanding of the knowledge and use of knowledge. This paper expounds the design process of the mould and the feasibility of the M10 washer in the practical design and manufacture.
Key words: M10 washer punching compound punching die process Die Design

从20世纪80年代初开始，发达国家的模具制造工业已经从机床工业中分离出来了，并且发展成为独立的工业部门，其产值已经超过了机床工业的产值。改革开放以来，国内的模具行业得到了迅速的发展，其产值也超过了机床工业的产值。中国的模具产业作为独立的产业
