摘 要
多股螺旋彈簧簡(jiǎn)稱多股簧。和單股彈簧相比，具有剛度強(qiáng)度好、吸振減振效果好等獨(dú)特性能，。但是多股簧制造工藝復(fù)雜，產(chǎn)品質(zhì)量難以控制、制造成本較高，目前還主要用于一些有特殊要求的場(chǎng)合多股簧的繞制條件包括：各加工主軸的轉(zhuǎn)速匹配；精確控制各股鋼絲的張力；柔性化制造等。因此，我們必須加強(qiáng)自主研發(fā)能力，研發(fā)出高精度和高生產(chǎn)效率的多股簧制造設(shè)備，生產(chǎn)出高質(zhì)量的多股簧，從而滿足我國(guó)國(guó)民生產(chǎn)和發(fā)展的需要。
本文首先分析了國(guó)內(nèi)外多股簧制造技術(shù)的現(xiàn)狀，以及多股簧制造過程中的關(guān)鍵技術(shù)和難點(diǎn)技術(shù)，并提出了相應(yīng)的解決方案，實(shí)現(xiàn)了鋼絲張力的在線檢測(cè)及動(dòng)態(tài)顯示。
本文采用了基于PC和ADAM- 5510的主從式控制方案，研究、設(shè)計(jì)了鋼絲張力控制器，并且在PC機(jī)與ADAM- 5510之間采用無(wú)線通訊的方式來(lái)實(shí)現(xiàn)對(duì)鋼絲張力的精確控制。在這兩個(gè)控制系統(tǒng)中，PC機(jī)為用戶提供良好的人機(jī)界面，以便于參數(shù)輸入及實(shí)時(shí)狀態(tài)監(jiān)測(cè)；而下位機(jī)則對(duì)執(zhí)行元件進(jìn)行控制并完成現(xiàn)場(chǎng)數(shù)據(jù)采集。最后，本文對(duì)該系統(tǒng)的控制軟件進(jìn)行了開發(fā)，建立了軟件模型，繪制了程序流程圖，并編制了功能完善、使用簡(jiǎn)便的人機(jī)界面。

ABSTRACT

Multi-wire helical spring is also called as multi-wire spring or stranded-wire spring. Because of its predominant characters compared with single-wire helical spring, multi-wire spring has been of great application value in many fields such as shock absorber of the automobile instruments, shooting system of weapon, aeroengine, etc. But its wider use is limited to some special fields by its complicated manufacturing process, difficult quality control and its high fabricating cost. The manufacturing technique and machine tool of stranded-wire spring in our country is dated and laggard compared with that of western developed countries. However, being considered as sensitive and crucial technic by western nations, the advanced manufacturing technique of stranded-wire spring is strictly forbidden to be obtained by Chinese. In order to break away from the serious dependence on stranded-wire spring imported, it is critically important to strengthen the ability of self-developing and improve machining level and product quality of stranded-wire spring.
This paper, firstly analyzes the present manufacturing technology and key technologies in the machining of stranded-wire spring, and proposes corresponding resolutions to succeed in the measurement and dynamic display of steel-wire tensile force.
This paper adopts the control system of PC and ADAM-5510. Because of the particularity of the machine tool, we adopt wireless communication to transmit signals between PC and ADAM-5510 in order to control and supervise the tension of steel wire. In both of the two control system, PC is used for supplying interface in order to input all manufacturing parameter and survey all machining conditions in time. Finally, this paper exploits the control software for the entire system, and finishes a favorable interface which could be use simply by workers.
