摘要:冷沖壓加工在我國已有很長的歷史，封建社會時期我國勞動人民純手工打造金、銀和銅飾品，制作各種日用品，就已顯示出精巧的工藝技術(shù)，但那時人們勞動強度大，制作時間長，不宜生產(chǎn)大量的生活用品供生活所需，隨著現(xiàn)今科技的進步，工業(yè)發(fā)展，模具在工業(yè)生產(chǎn)中引起了人們的重視。沖壓模具生產(chǎn)產(chǎn)品效率高，能保證工件的精度，實現(xiàn)了自動化，適合大批量生產(chǎn)。未來模具將向全面推廣CAD/CAE/CAM,模具優(yōu)質(zhì)材料及表面處理技術(shù)，特種加工，模具掃描及數(shù)字化系統(tǒng)，模具研磨拋光將自動化、智能化，模具自動加工系統(tǒng)方向發(fā)展。 本設(shè)計是對漏油器外殼的落料、拉深、沖孔級進模的設(shè)計，完成的內(nèi)容為：對模具在工業(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。進行零件的形狀、尺寸、精度工藝分析，確定合理的工藝方案，確定工序數(shù)目。確定毛坯尺寸，判斷能否一次拉成，合理排樣，繪制排樣圖，計算沖裁力、推件力、頂件力、卸料力、拉深力，確定壓力中心。確定拉深凸、凹模間隙，計算落料、拉深、沖孔的凸、凹模刃口尺寸。確定凸、凹模結(jié)構(gòu)，并繪制零件圖，設(shè)計定位零件，壓料、卸料、出件零部件，設(shè)計固定零件，選擇模架標注緊固件。最后繪制模具非標準零件圖，用CAD和UG分別畫出二維與三維裝配圖，三維圖并生成爆炸圖。 本設(shè)計運用模具使鋼料產(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，并且利用級進模生產(chǎn)零件，提高了生產(chǎn)效率，對相似工件的大批量生產(chǎn)具有參考的作用。 關(guān)鍵詞：漏油器外殼; 落料; 拉深; 沖孔;級進模
Abstract:Cold stamping has a long history in China. The period of feudal society, our working people handmade gold, silver and copper jewelry, production of daily necessities, Already shows a sophisticated technology, But then the people to the labor intensity of production a long time, should not produce large amounts of daily necessities for living expenses. With today'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 comprehensively promote the automation of CAD / CAE / CAM, mold-quality 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 non-standard parts diagram, draw 2D and 3D assembly drawings, three-dimensional 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, multi-process production methods overlap, and progressive die production parts, improve production efficiency, similar to the workpiecehigh-volume production with reference to the role. Keywords: Oil spill shell; Blanking; drawing; punching; Progressive Die
