摘 要
本設(shè)計(jì)課題進(jìn)行了拉深,翻邊復(fù)合模具的設(shè)計(jì)。文中簡要概述了沖壓模具目前的發(fā)展?fàn)顩r和趨勢。對產(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、卸料板、定位裝置等。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固定擋料銷。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位置準(zhǔn)確,提高加工精度。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。
關(guān)鍵詞: 復(fù)合模,沖孔,翻邊,拉深
Abstract
The paper is the banking or punching and bending composite die design. This paper briefly outlined the Stamping Die current development status and trends. The product is 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, feet behind the sales, market and other derivative is. Die-standard model planes need to choose suitable stamping equipment. Sign work on the parts and specifications will press for the necessary checking calculation. In addition, the die block used only with marketing materials and immovable the marketing materials. Blanking punch contents is a derivative sale, and guarantees the work piece and the shape of the holes in the relative position, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and mass production requirements.
KEY WORDS : composite die, Punching, Blanking, drawing
