汽車水泵葉輪沖壓工藝與模具設計摘要工業(yè)生產(chǎn)中普遍采用模具成型工藝方法，有效地保證了產(chǎn)品的生產(chǎn)率和質(zhì)量，使操作技術簡化，還能省料、節(jié)能，獲得顯著的經(jīng)濟效益。由于產(chǎn)品的材料和工藝特性不同，生產(chǎn)用的設備也各異，模具種類繁多，但用的最為廣泛的大約有以下幾種：冷沖壓模、塑料成型模、鍛造模、精密鑄造模、粉末冶金模、橡膠成型模、玻璃成型模、窯業(yè)制品模、食品糖果模、建材用模等。其中以冷沖壓模、塑料模的技術要求和復雜程度較高。設計內(nèi)容是從零件的工藝性分析開始的，根據(jù)工藝要求來確定設計的大體思路。其開始是確定該模具類型為落料、拉深復合模，做工藝計算，確定模具的壓力中心，計算出沖裁時的拉深力、沖壓力、卸料力、整形力，最后根據(jù)前面所計算出的內(nèi)容確定模具的凸、凹模的刃口尺寸和形狀。設計出定位方式、卸料裝置、頂件裝置、模架等模具的主要零部件，并確定沖模的閉合高度從而選擇壓力機，完成整個模具的設計工作。模具主要零部件結(jié)構(gòu)設計是模具設計的主要內(nèi)容，其內(nèi)容包含了凹模結(jié)構(gòu)設計、凸模結(jié)構(gòu)設計、定位零件、彈性卸料裝置、導柱與導套、模柄與模架的選取等重要零部件的設計加工方法和加工注意要點。這樣更有利于加工人員的一線操作，使其通俗易懂加工方便。本次設計不僅讓我熟悉了課本所學的知識，而且讓我做到所學的知識靈活運用到實踐當中，更讓我了解了沖壓模具設計的全過程和加工實踐中應注意的要點。使我從畢業(yè)設計中更好理解了模具實際生產(chǎn)中的重要性。 關鍵詞：落料，拉深，沖孔，整形Auto water pump impeller stamping process and die design AbstractThe molding process methods commonly used in industrial production, and effectively ensure the productivity and quality of the product, so that the operating technology to simplify, but also material saving, energy saving, significant economic benefits. Materials and workmanship of the product characteristics, production equipment also vary a wide range of mold, but the most widely used in approximately the following: cold stamping mold, plastic molding, forging mold, the mold of precision casting, powder metallurgy mold, rubber molding, glass molding, ceramic products, mold, food candy mold, building materials and mold.Among them, the high technical requirements and complexity of the cold stamping mold, plastic mold. Design from the parts of the process began, according to process requirements to determine the design of the general idea. The start is to determine the mold type blanking, deep drawing composite mode, doing process calculation to determine the center of pressure of the mold, the drawing force calculated punching, punching pressure, discharge power, shaping force, the last earlier content calculated to determine the edge size and shape of the mold of convex and concave mold. Design the main components of the positioning method, unloading equipment, roof installation, mold, mold, and to determine the die shut height to select presses to complete the design work of the entire mold.The mold structure design of the main components is the main content of the mold design, its content includes the structural design of the die the punch structural design, locate parts, elastic unloading equipment, guide post, guide sleeve, die handle and mold selection of importantprocessing methods and processing of parts of the design points to note. This is more conducive to processing first-line operation, make it easy to understand and easy to process.This design not only familiar with the textbook knowledge learned, but I do have learned flexibility to practice, made me understand the main points should be noted that in the whole process of stamping die design and processing practices. Make me a better understanding of the importance of actual production of the mold from the graduation project.Keywords: Blanking, deep drawing, punching, shaping.
