摘要
沖壓作為一個(gè)行業(yè)，在國(guó)民經(jīng)濟(jì)的加工工業(yè)中占有重要的地位，在國(guó)民經(jīng)濟(jì)的各個(gè)部門(mén)中，幾乎都有沖壓加工產(chǎn)品。沖裁工藝和彎曲工藝作為沖壓生產(chǎn)的兩個(gè)重要工藝方法，在沖壓生產(chǎn)中應(yīng)用非常廣泛，得到去產(chǎn)品既可以直接作為零件使用，又可以作為進(jìn)一步加工的毛坯。
隨著科技的進(jìn)步，生產(chǎn)力的提高和競(jìng)爭(zhēng)的加劇，對(duì)沖壓工藝的要求越來(lái)越高。而計(jì)算機(jī)技術(shù)的發(fā)展，尤其是CAD/CAE/CAM等技術(shù)的快速發(fā)展，使進(jìn)一步深入研究沖壓工藝過(guò)程成為可能。本文以一種對(duì)保險(xiǎn)絲沖孔、折彎的組合機(jī)床為研究對(duì)象，以研究板料沖孔和折彎工藝過(guò)程及其成形裝置，同時(shí)完成沖孔折彎工藝過(guò)程的優(yōu)化，本文主要進(jìn)行了以下研究工作：
(1) 根據(jù)塑性成形理論、沖壓工藝等基礎(chǔ)理論，深入分析沖孔工藝和折彎工藝，在此基礎(chǔ)上了解了沖孔工藝和折彎工藝的技術(shù)問(wèn)題和相應(yīng)的改善或解決方法。
(2) 研究了產(chǎn)品在機(jī)床上的沖孔過(guò)程，根據(jù)《沖孔折彎設(shè)備技術(shù)協(xié)議》及沖孔工藝的理論知識(shí)和生產(chǎn)實(shí)際，分析了加工方案和加工過(guò)程的合理性和可行性。
(3) 分析了沖孔工藝的裝置的結(jié)構(gòu)組成及主要零部件的作用，使用Pro/E軟件對(duì)沖孔裝置的關(guān)鍵運(yùn)動(dòng)部分進(jìn)行運(yùn)動(dòng)仿真，保證了加工過(guò)程的安全、合理、高效。
(4) 研究了產(chǎn)品在機(jī)床上的折彎過(guò)程，分析了經(jīng)沖孔加工后工件的形狀、結(jié)構(gòu)、尺寸，根據(jù)《沖孔折彎設(shè)備技術(shù)協(xié)議》及彎曲工藝的理論知識(shí)和生產(chǎn)實(shí)際，對(duì)折彎工藝進(jìn)行了優(yōu)化。
(5) 分析了折彎工藝的裝置的結(jié)構(gòu)組成及主要零部件的作用，在確保零件的質(zhì)量的前提下，提高生產(chǎn)效率，降低加工成本，獲得最好的經(jīng)濟(jì)效益。
(6) 介紹了實(shí)際的沖孔折彎?rùn)C(jī)的樣機(jī)以及樣機(jī)加工出來(lái)的保險(xiǎn)絲產(chǎn)品
本課題主要研究一種對(duì)保險(xiǎn)絲沖孔、折彎的組合機(jī)床的成形工藝及裝置。該機(jī)床將保險(xiǎn)絲的沖孔、折彎兩道工序組合到一起，能在30秒內(nèi)完成6根保險(xiǎn)絲的加工。本文主要對(duì)該設(shè)備沖孔折彎部分的功能分析、部件選用、結(jié)構(gòu)設(shè)計(jì)以及各工序設(shè)計(jì)方案進(jìn)行了研究。

Abstract
Stamping, as an industry, occupies an important position in the national economy of the processing industry, stamping products exist in various sectors of the national economy. Blanking process and bending process, as two important processes in stamping, are widely used in stamping producing, the products got from these two processes can be directly used as parts, or as blanks in the further processing .
With the advances in science & technology, improved productivity and increased competition, the requirement on the stamping process becomes higher and higher. The development of computer technology, especially the rapid development of CAD / CAE / CAM technology, makes further research on stamping process possible. In this paper, a kind of fuse punching, bending combination machine for the study, research punching and bending sheet metal forming processes and devices, while optimizing punching bending process is completed, the paper mainly conducts the following research:
(1) According to the basic theory of plasticity theory forming , stamping and crafts, this paper makes in-depth analysis of punching and bending process technology , based on this understanding, the technical problems in punching and bending processes and corresponding technology improvement or solution are got.
(2) This paper studied the punching process of the product on the machine , according to the "Foton production line - Punching Bending Equipment Technology Agreement 2014-2-10 " theoretical knowledge and practical producing experience in punching ,this paper analyzed the of the processing solutions.
(3) This paper analysed the punching process device structures and the function of major components , used Pro / E software to simulate the critical moving parts in punching motion device, that ensured that the process is safe , rational , efficient.
(4) The paper studied the bending process on the machine, analyzed the workpiece shape, structure, size after punching, according to the "Foton production line - Punching Bending Equipment Technology Agreement 2014-2-10 " and the bending process theoretical knowledge and practical production process, the bending process was optimized .
(5) This paper analyzed bending process device structures and the function of the major components, under the premise of ensuring the quality of parts , increase productivity, reduce processing costs and get the best value for money.
(6) This paper introduced the actual prototype of punching bending machine and the fuse it produced.
This paper mainly studies the design of punching and bending of a kind of fuse. This combination machine tool together the punching and bending processes. And it can finish the processing of six fuses within 30 seconds. This paper focuses on the introduction of functional analysis, component selection, structure design and each process design of this equipment.

Key Words: Punching and bending, Functional analysis, Process analysis, Device study
