【正文】 ：對(duì)模具在工業(yè)生產(chǎn)中的作用，模具發(fā)展歷史與現(xiàn)狀，未來模具的發(fā)展前景做了概述。確定毛坯尺寸，判斷能否一次拉成，合理排樣，繪制排樣圖，計(jì)算沖裁力、推件力、頂件力、卸料力、拉深力，確定壓力中心。確定凸、凹模結(jié)構(gòu)，并繪制零件圖，設(shè)計(jì)定位零件，壓料、卸料、出件零部件，設(shè)計(jì)固定零件，選擇模架標(biāo)注緊固件。 本設(shè)計(jì)運(yùn)用模具使鋼料產(chǎn)生塑性變形，獲得最終需要的零件，這是一種少切削、無切削、多工序重合的生產(chǎn)方法，并且利用級(jí)進(jìn)模生產(chǎn)零件，提高了生產(chǎn)效率，對(duì)相似工件的大批量生產(chǎn)具有參考的作用。 落料 。 沖孔 。s advances in technology, industrial development, attracted the attention of people die in industrial production. Stamping mold products, high efficiency, to ensure the precision of the workpiece, automated, suitable for mass production. The mold will prehensively promote the automation of CAD / CAE / CAM, moldquality materials and surface treatment techniques, special machining, mold scanning and digitizing systems, mold grinding polishing, intelligent, mold automatic processing system direction. This design is the oil spill shell blanking, deep drawing, Punching Progressive Die Design, Completed as follows : The role of mold in industrial production, mold development history and current situation, future prospects for the development of the mold to do an overview. The part shape, size, precision and process analysis , To determine a reasonable process , To determine the process number, To determine the blank size, to determine whether to pull into for a time, Reasonable layout, drawing layout diagram, Calculate the blanking force, pushing pieces of force, the top pieces of force, the discharge power, drawing force, determine the center of pressure. Make sure the convex drawing, the die gap to calculate the convexity of the blanking, deep drawing, punching, and the die edge size. Determine the convex and concave mold structure, and draw the parts diagram, locate the part of the design, binder, discharge, the piece parts, design of fixed parts, select mold label fasteners. Finally draw the mold nonstandard parts diagram, draw 2D and 3D assembly drawings, threedimensional map with CAD and UG, respectively, and generates the exploded diagram. The use of design mold steel material of the plastic deformation, to obtain the final parts, this is a little cutting, cutting, multiprocess production methods overlap, 畢業(yè)論文 （設(shè)計(jì)） III and progressive die production parts, improve production efficiency, similar to the workpiecehighvolume production with reference to the role.
