摘要
冷沖壓是一種先進(jìn)的金屬加工方法，它是建立在金屬塑性變形的基礎(chǔ)上，利用模具和沖壓設(shè)備對(duì)板料金屬進(jìn)行加工，以獲得所需要的零件形狀和尺寸。
本課題研究墊片的沖壓模具的設(shè)計(jì)，通過(guò)對(duì)工件的分析采用復(fù)合模進(jìn)行生產(chǎn)。復(fù)合模的主要優(yōu)點(diǎn)是生產(chǎn)率和精度高，適合大量生產(chǎn)。其缺點(diǎn)是模具結(jié)構(gòu)復(fù)雜，不易制造。
本課題的內(nèi)容包括，排樣設(shè)計(jì)、凸模設(shè)計(jì)、凹模設(shè)計(jì)、沖裁力計(jì)算、壓力中心的確定、沖壓機(jī)構(gòu)的選擇，模具刃口尺寸確定和結(jié)構(gòu)設(shè)計(jì)等。

Abstract
Cold stamping is an advanced metal processing method, which is based on the plastic deformation of metals on the basis of the use of molds and stamping equipment for sheet metal processing to obtain the necessary components shapes and sizes.
The research of cold stamping sheet before the fixed stamping die design, through the analysis of the workpiece using composite model production. Composite modulus of the main advantages of high productivity and accuracy and is suitable for mass production. The drawback is mold structure complex and difficult to manufacture.
The topics will include, layout design, punch design, die design, punching power, the center of pressure, Stamping the choice Die determine the size and structure design.
Keywords : stamping; Composite molding;
