防塵蓋沖壓模具設(shè)計(jì)
摘要：本設(shè)計(jì)進(jìn)行了落料、沖孔、拉深復(fù)合模的設(shè)計(jì)。文中簡(jiǎn)要概述了沖壓模具目前的發(fā)展?fàn)顩r和趨勢(shì)。對(duì)產(chǎn)品進(jìn)行了詳細(xì)工藝分析和工藝方案的確定。按照沖壓模具設(shè)計(jì)的一般步驟，計(jì)算并設(shè)計(jì)了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、墊板、凹模固定板、卸料板、導(dǎo)尺、擋料銷、導(dǎo)正銷等。模架采用標(biāo)準(zhǔn)模架，選用了合適的沖壓設(shè)備。設(shè)計(jì)中對(duì)工作零件和壓力機(jī)規(guī)格均進(jìn)行了必要的校核計(jì)算。此外，本模具采用始用擋料銷和鉤形擋料銷擋料。模具的沖孔和落料凸模分別用不同的固定板固定，便于調(diào)整間隙；沖孔凹模和落料凹模則采用整體固定板固定。落料凸模內(nèi)裝有導(dǎo)正銷，保證了工件上孔和外形的相對(duì)位置準(zhǔn)確，提高了加工精度。如此設(shè)計(jì)出的結(jié)構(gòu)可確保模具工作運(yùn)行可靠和沖壓產(chǎn)品大批量生產(chǎn)的要求。

Abstract：The design of the blanking and punching, drawing composite modulus design. This paper briefly outlined the Stamping Die current development status and trends. The product of a detailed analysis and the identification process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as : punch and die. Punch plate, plate, Die plate and dump plates I. feet behind the sales, marketing and other derivative is. Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. In addition, the die block used only with marketing materials and Crook block behind the marketing materials. Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate. Blanking punch contents is a derivative sales, and guarantee the workpiece and the shape of the holes in the relative position accurately, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and mass production requirements.
Keywords : composite modules Check Punching Blanking Drawing.
