【摘要】：現(xiàn)代工業(yè)中對金屬板材的折彎已經(jīng)成為鈑金行業(yè)加工中的一個(gè)不可缺少的環(huán)節(jié),并已經(jīng)逐步在鈑金加工行業(yè)中占據(jù)了重要位置。在對折彎機(jī)床的研究中發(fā)現(xiàn)在選用液壓補(bǔ)償系統(tǒng)方式時(shí),有響應(yīng)速度慢、補(bǔ)償變量線性差、維修成本高以及對環(huán)境有污染等缺點(diǎn)。隨著電力、電子技術(shù)及電機(jī)制造技術(shù)的發(fā)展,新型的以電機(jī)直接驅(qū)動折彎機(jī)床的機(jī)械補(bǔ)償系統(tǒng),替代折彎機(jī)床的液壓補(bǔ)償系統(tǒng)成了新的發(fā)展方向。機(jī)械補(bǔ)償系統(tǒng)為折彎機(jī)床提供了一套比液壓補(bǔ)償系統(tǒng)響應(yīng)速度快、工作補(bǔ)償量可以實(shí)現(xiàn)線性補(bǔ)償,并且在工作中有非常良好的穩(wěn)定等優(yōu)點(diǎn)。在本次設(shè)計(jì)過程中學(xué)習(xí)了折彎機(jī)床的基本工作原理,同時(shí)對折彎機(jī)床行業(yè)在國內(nèi)外當(dāng)前的市場現(xiàn)狀的發(fā)展趨勢進(jìn)行了細(xì)致研究,在研究中發(fā)現(xiàn)液壓補(bǔ)償系統(tǒng)在金屬鈑材折彎生產(chǎn)中發(fā)現(xiàn)的缺點(diǎn)不足進(jìn)行總結(jié),我們將這些不足和困難做為機(jī)械補(bǔ)償系統(tǒng)設(shè)計(jì)方案中的攻關(guān)要點(diǎn)。首先對機(jī)械補(bǔ)償系統(tǒng)在補(bǔ)償增量和參數(shù)上進(jìn)行分析研究并擬定設(shè)計(jì)方案,同時(shí)運(yùn)用有限元分析對機(jī)架和滑塊進(jìn)行靜力學(xué)分析。通過研究分析找到替代液壓補(bǔ)償控制系統(tǒng)在穩(wěn)定性和補(bǔ)償增量的線性變化的不足解決方案。針對這些問題,機(jī)械補(bǔ)償?shù)姆桨甘峭ㄟ^驅(qū)動電機(jī)帶動機(jī)械補(bǔ)償內(nèi)部的補(bǔ)償斜塊,通過補(bǔ)償斜塊的相對移動來完成折彎工藝中的補(bǔ)償工作。在調(diào)研企業(yè)的大力支持下應(yīng)用了我們的設(shè)計(jì)方案,在數(shù)控電液折彎機(jī)床上以機(jī)械補(bǔ)償系統(tǒng)替代液壓補(bǔ)償系統(tǒng)的設(shè)計(jì)方案讓機(jī)床的加工精度得到了顯著提升。
[Abstract]:The bending of sheet metal in modern industry has become an indispensable tache in the sheet metal processing industry, and has gradually in sheet metal processing industry occupies an important position. In the research of bending machine tool found in the selection of hydraulic compensation system, response speed, variable linear compensation, high maintenance costs. And the pollution to the environment. With the disadvantages of power electronic technology and the development of motor manufacturing technology, new type of direct drive motor mechanical compensation system of bending machine, hydraulic bending machine replacement compensation system has become a new development direction. Provides a set of hydraulic compensation system response speed than the mechanical compensation system for bending machine the amount of compensation, work can realize linear compensation, and has the advantages of stable and very good at work. In the design process of learning the basic work of bending machine At the same time, the development trend of the principle of bending machine tool industry in the current market situation at home and abroad was studied in detail, it was found that the lack of disadvantages of hydraulic compensation system found in the metal sheet metal bending production were summarized, the problems and difficulties we will do for the mechanical compensation system design in the key points. Firstly, analysis design research and development of mechanical compensation system and compensation in the incremental parameter, and finite element analysis on the frame and slider static analysis application. Through research and analysis to find alternative hydraulic compensation inadequate control of linear variation in stability and incremental compensation system solutions. To solve these problems, the scheme is driven by mechanical compensation the motor drives the compensation inclined block mechanical compensation inside, to complete the work in the process of bending compensation by relative motion compensation. In the inclined block With the support of research enterprises, our design scheme is applied. The design scheme of the hydraulic compensation system is replaced by the mechanical compensation system on the CNC electro-hydraulic bending machine. The machining accuracy of the machine tool has been significantly improved.
