濾清器固定架沖壓模具設(shè)計
摘 要 沖壓成形是一個涉及領(lǐng)域極其廣泛的行業(yè)，深入到制造業(yè)的每個方面，沖壓成形加工主要是通過沖壓模具來實(shí)現(xiàn)。沖壓模具是大批量生產(chǎn)同類產(chǎn)品的工具，是沖壓成形的常用工藝裝備。
本設(shè)計首先根據(jù)空氣濾清器固定架沖壓件的結(jié)構(gòu)特點(diǎn)、生產(chǎn)批量、加工精度進(jìn)行沖壓工藝性分析，確定沖壓工藝方案?？諝鉃V清器固定架成型工序包括兩個大的部分：一部分是板材的沖孔落料，另一部分為材料的彎曲工藝。因此，由沖壓工藝性分析所確定的沖壓工藝方案是設(shè)計四套模具，分別是沖孔、落料復(fù)合模、中間彎曲單工序模、外角彎曲單工序模，外角彎曲單工序模。然后對這四套沖壓模具進(jìn)行工藝計算并設(shè)計每套模具所用的零部件：凸模、凹模、凹模固定板、卸料板、彎曲模等。按照沖壓模具的設(shè)計的步驟，對各套沖壓模具選用合適的導(dǎo)柱、導(dǎo)套、模柄及模架等標(biāo)準(zhǔn)件。最終完成空氣濾清器固定架沖壓件的模具設(shè)計。

ABSTRACT
Abstract： The stamping is a very wide range of the areas of industry, into all aspects of manufacturing, stamping forming processing to achieve through the stamping die. The stamping dies are the tools of mass production of similar products is the main process of stamping equipment.
The design is first based on the structural characteristics of the air filter holder stampings, production volume, processing precision stamping process analysis to determine the program of stamping process. The air filter holder molding processes, including punching, blanking, bending, stamping process determined by the stamping process analysis program is to design three sets of mold, namely, punching, blanking, bending single-process mode, punching down composite material, bending mode, punching and blanking, bending the middle, both ends of the curved composite mode. And then punching, blanking, bending single-process mode, punching and blanking, bending composite mold, punching and blanking the middle bend, both ends of the curved composite mode, three sets of stamping die process calculation and design of each mold parts: punch, die, punch fixed plate and the fixed plate of the die, stripper plate, bending modulus and so on. In accordance with the steps of stamping die design different sets of stamping dies, the appropriate choice of guide posts, guide sleeve, die handle and mold standard parts. The final completion of the air filter holder of stamping mold design.
Key words： Stamping process；Punching blanking the composite modulus；Bending mode
