落料,正反拉深复合模毕业设计

落料、正、反拉深模具 课程设计 系 别:专 业:学 号:姓 名:指导教师: 2012年月 指导教师: 学生: 关键词 毕业论文;模具设计;复合模;正反拉深 ABSTRACT As Chinas industrial continuously development, mould industry is becoming more and more important. This paper is the design process blanking, positive, FanLa deep mould. Firstly the processing parts processing technology and structure analysis of the process. Through the calculation blank dimensions and drawing coefficient puts forward four kinds of solutions, the final determination by blanking, positive and negative drawing compound die. To mould layout made reasonable decorate, make material utilization reached a high level. To calculate the stamping process need all kinds of stamping technology force, including blanking force, discharge power, blank-holder force, drawing force, lifter force, etc., and to press the reasonable tonnage primaries. Composite die on the structure adopted the form of dress, calculated the blanking, are drawing and FanLa deep working portion size. To mould height on the determination of reasonable, but also to design the mould of the main parts blanking die, die and punch, FanLa deep punch, FanLa deep concave die, die fixed plate, etc. Lists the required detailed list of mould parts, and gives a reasonable assembly drawing. Because of the depth of the deep drawing greatly, the press of motor has also carried on the power check and puts forward the lubrication additional process, can make the drawing complete. Finally, the mould a main part guide sleeve of a simple processing technology route formulation. This design for the single action press on positive and negative drawing to have the certain reference function.
