摘 要

沖壓模具在實際工業(yè)生產(chǎn)中應(yīng)用廣泛。在傳統(tǒng)的工業(yè)生產(chǎn)中，工人生產(chǎn)的勞動強度大、勞動量大，嚴(yán)重影響生產(chǎn)效率的提高。隨著當(dāng)今科技的發(fā)展， 工業(yè)生產(chǎn)中模具的使用已經(jīng)越來越引起人們的重視，而被大量應(yīng)用到工業(yè)生產(chǎn)中來。沖壓模具的自動送料技術(shù)也投入到實際的生產(chǎn)中，沖壓模具可以大大的提高勞動生產(chǎn)效率，減輕工人負(fù)擔(dān)，具有重要的技術(shù)進步意義和經(jīng)濟價值。
本文對冷沖壓技術(shù)的分類、特點及發(fā)展方向作了簡略概述；論述了沖壓零件的形成原理、基本模具結(jié)構(gòu)與運動過程及其設(shè)計原理；對典型的沖壓件模具進行了設(shè)計：底腳沖壓復(fù)合模設(shè)計解決了四角形彎曲件的加工難題、帶有浮動凸模的彎曲復(fù)合模設(shè)計、在室溫的條件下對坯件進行沖壓成形，生產(chǎn)效率提高，經(jīng)濟效益顯著。
本文介紹的模具實例結(jié)構(gòu)簡單實用，使用方便可靠，對類似工件的大批量生產(chǎn)具有一定的參考作用。

THE DESIGN OF BENDING DIE FOR THE FEET

ABSTRACT

Punching die has been widely used in industrial production.In the traditional industrial production,the worker work very hard,and there are too much work,so the efficiency is low.With the development of the science and technology nowadays,the use of punching die in the industial production gain more attention, and be used in the industrial production more and more.Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value.
The article mainly discussed the classification,feature and the developmental direction of the pnnching technology. Elaborated the punching components formation principle, the basic dies structure and the rate process and the principle of design; and designed some conventional punching die:the die for the feet have saved the trouble of the punching .for The punching dies that utilized the feature of the normal punch shaped the workpiece in the room temperature,and its efficiency and economic situation is excellent.
The dies here discussed can be easily made,conveniently used, and safely operated.And it could be used as the reference in the large scale production of similar workpieces.
