摘  要
 
随着中国工业不断地发展，模具行业也显得越来越重要。本论文便是设计加工端盖的模具。首先对加工零件进行了加工工艺和结构工艺的分析。通过计算毛坯尺寸和拉深系数提出了方案，最后确定采用落料、拉深复合模。对模具的排样做出了合理的布置，使材料利用率达到较高的水平。计算了冲压过程中所需要的各种冲压工艺力，包括落料力、卸料力、压边力、拉深力、顶料力等，并对压力机进行了合理的吨位初选。复合模在结构上采用了装的形式，计算出了落料、拉深工作部分的尺寸。对模具的闭合高度进行了合理的确定。列出了模具所需零件的详细清单，并给出了合理的装配图。由于拉深的深度较大，对压力机的电机也进行了功率校核并提出了，能使拉深顺利完成。最后对模具的一个主要零件导套进行了简单的加工工艺路线的制定。本设计对于采用单动压力机进行拉深具有一定的参考作用。

Abstract

With the continuous development of Chinese industry, the mold industry has become increasingly important. This paper is designed to cover the mold machining. First of machined parts were analyzed process and structure the process. By calculating the rough size and drawing coefficient proposed plan to finalize the use of blanking, drawing compound die. Nesting on the mold to make a reasonable arrangement, the material utilization rate reached a higher level. Calculate the force of stamping process the stamping process needs, including blanking force, discharge power, BHF, drawing force, ejector force, etc., and press for a reasonable tonnage primaries. Composite mold in the structure adopted in the form of equipment, calculated blanking, drawing deep working portion size. The mold is closed for a reasonable determination of the height. Lists the detailed list of the required mold parts, and gives a reasonable assembly drawing. Since the depth of the larger drawing of the press motor were also checked and made power, enabling the successful completion of the drawing. Finally, a major part of the mold guide sleeve for a simple process route development. The design for a single-action press were drawing has a certain reference.
