【摘要】：在空調(diào)用銅管的加工中,不管是采用擠壓工藝還是行星旋軋工藝都離不開一道銑面的工序,其作用是銑掉鑄坯表面的氧化皮好進(jìn)行下一道工序。銑面機(jī)有旋風(fēng)銑和臥銑兩種,其中臥銑生產(chǎn)效率高,適合于行星旋軋工藝的快節(jié)奏。由于連鑄時的各種干擾因素和吊裝、轉(zhuǎn)運(yùn)、存放時的受力不均、振動等因素的影響,鑄坯都有一定程度的彎曲。目前在國內(nèi)的空調(diào)銅管加工行業(yè)中銑面機(jī)執(zhí)行機(jī)構(gòu)普遍采用機(jī)械支撐,對鑄坯彎曲的隨動性不好。銑削過程中對銑刀、銑刀軸有沖擊甚至于銑不凈氧化皮,生產(chǎn)效率低,維護(hù)成本高。因此設(shè)計研發(fā)銑面機(jī)執(zhí)行機(jī)構(gòu)的位置控制系統(tǒng)成為了當(dāng)前的重要課題。 本文在查閱大量國內(nèi)外有關(guān)文獻(xiàn)的基礎(chǔ)上,提出了采用液壓伺服控制的位置控制系統(tǒng),綜述了液壓伺服系統(tǒng)的研究現(xiàn)狀和實(shí)際應(yīng)用情況。針對生產(chǎn)實(shí)際中的問題,提出采用基于力反饋的位置控制系統(tǒng)。 詳細(xì)闡述了此液壓伺服系統(tǒng)中關(guān)鍵參數(shù)的確定、元件的選型,為系統(tǒng)的研發(fā)奠定基礎(chǔ)。對液壓系統(tǒng)中所涉及到的關(guān)鍵問題和主要技術(shù)進(jìn)行了仔細(xì)的研究。從生產(chǎn)實(shí)際出發(fā),確定采用位置控制的液壓伺服系統(tǒng),從滑閥流量方程、流量連續(xù)性方程以及力平衡方程對其進(jìn)行模型建立,并對其進(jìn)行整理并結(jié)合其他環(huán)節(jié)得到系統(tǒng)的數(shù)學(xué)模型。 設(shè)計力—位移轉(zhuǎn)換環(huán)節(jié)實(shí)現(xiàn)對鑄坯軸線彎曲的補(bǔ)償。對系統(tǒng)進(jìn)行了計算機(jī)仿真,通過仿真研究系統(tǒng)位置控制的動態(tài)特性,并分別引入PID和模糊PID控制器對系統(tǒng)進(jìn)行校正,使其能夠滿足生產(chǎn)實(shí)際的要求。
[Abstract]:In the processing of copper tubes used in air conditioning, either the extrusion process or the planetary rotary rolling process can not be separated from the process of milling a surface, the function of which is to mill off the oxidized skin on the surface of the billet and carry on the next process. There are two kinds of milling machines: whirlwind milling and horizontal milling. The production efficiency of horizontal milling is high, which is suitable for the fast rhythm of planetary rotary rolling process. Due to the influence of various interference factors during continuous casting and hoisting, transportation, storage force uneven, vibration and other factors, At present, mechanical support is widely used in the executive mechanism of milling machine in the domestic air conditioning copper pipe processing industry, which is not easy to follow the bending of the billet, and the milling cutter is applied to the milling cutter in the course of milling. Because of the impact of milling cutter shaft and the low production efficiency and high maintenance cost, it has become an important issue to design and develop the position control system of the executive mechanism of milling machine. On the basis of consulting a large number of domestic and foreign literatures, this paper puts forward a position control system with hydraulic servo control, summarizes the research status and practical application of hydraulic servo system, and aims at the problems in production practice. A position control system based on force feedback is proposed. The determination of key parameters and the selection of components in the hydraulic servo system are described in detail, which lays a foundation for the research and development of the system. The key problems and main technologies involved in the hydraulic system are carefully studied. The hydraulic servo system with position control is established from the flow equation, flow continuity equation and force balance equation of the sliding valve, and the mathematical model of the system is obtained by sorting it out and combining with other links. The system is simulated by computer, and the dynamic characteristics of position control of the system are studied by simulation. The system is corrected by introducing PID and fuzzy PID controller, respectively. To enable it to meet the actual requirements of production.
