摘 要

多股簧，它是由數(shù)根（2~7根）鋼絲擰成鋼索后纏繞成的彈簧，與單股螺旋彈簧相比，不僅機(jī)械強(qiáng)度高，而且具有非常好的減振效果，因此在汽車儀器儀表減振系統(tǒng)、武器發(fā)射系統(tǒng)以及航空發(fā)動(dòng)機(jī)等多個(gè)領(lǐng)域中都具有重要的應(yīng)用價(jià)值。
本文通過(guò)分析國(guó)內(nèi)外多股簧制造技術(shù)的現(xiàn)狀得知，精確的張力控制是直接影響產(chǎn)品質(zhì)量和生產(chǎn)效率的關(guān)鍵技術(shù)。通過(guò)對(duì)鋼絲張力控制要求的分析，本文采用了磁式制動(dòng)器的制動(dòng)原理，通過(guò)改變激磁電流，而控制阻力盤扭矩的傳遞，實(shí)現(xiàn)全自動(dòng)張力自動(dòng)調(diào)節(jié)的控制，有效避免了鋼絲在卷制過(guò)程中可能產(chǎn)生的變形，從而保證了彈簧的質(zhì)量。
本畢業(yè)設(shè)計(jì)完成了該張力機(jī)構(gòu)的機(jī)械原理圖、裝配結(jié)構(gòu)圖以及部分零件圖的設(shè)計(jì)工作，并闡述了該機(jī)構(gòu)的控制原理和控制過(guò)程，總結(jié)了其設(shè)計(jì)過(guò)程中的創(chuàng)新點(diǎn)、結(jié)構(gòu)特點(diǎn)和適用范圍。

ABSTRACT

Stranded-wire helical spring has many predominant characters compared with single-wire helical spring. So it has been of great application value in many fields such as shock absorber of the automobile instruments, shooting system of weapon, aero engine, etc.
By analyzing the requirements of the control of steel wire’s tensility ,this article adopts the brake principle of magnetic brake . To control the delivery of resistance torque, altering magnet current .So as to make the tensility adjust automatically and avoid the possible deformity of the steal wire in the rolling process. Therefore, the quality of the spring can be guaranteed.
The text including the assembling drawings of machine，the configuration and the correlative hardwares drawings. Then expatiate the functionary mechanism of the machine particularly. It is not only able to solve relative technical difficulties, but also succeed to improve the quantity and productivity of stranded-wire spring, and depresses the work intensity of workers. Moreover, it is capable of achieving flexible manufacturing and satisfying the need of production and life in our country.
