摘 要
本課題主要是研究根據(jù)彎管機(jī)的工藝流程對(duì)彎管機(jī)的控制系統(tǒng)進(jìn)行分析和數(shù)學(xué)建模，確定適用于該系統(tǒng)的控制算法，完成理論與實(shí)踐的結(jié)合。
彎管機(jī)主要由機(jī)械裝置、液壓系統(tǒng)、等組成。機(jī)械裝置主要有卡緊裝置、小車推進(jìn)裝置、導(dǎo)向輪裝置和搖臂回轉(zhuǎn)裝置等組成。
其工作原理是采用液壓缸將鋼管勻速推進(jìn)，使鋼管沿預(yù)設(shè)的軌道行走從而形成具有一定曲率半徑和角度的彎管。先將鋼管安裝就位，通過搖臂回轉(zhuǎn)裝置上的絲杠絲母?jìng)鲃?dòng)裝置調(diào)整好彎曲半徑，從而獲得所需的彎管管件。特點(diǎn)：彎出的管具有形變小，壁厚差小，無應(yīng)力。

Abstract
Běnwén zhǔyào yǐ SPCE061A wèi jīchǔ jiè shào liǎo rúhé yìngyòng SPCE061A xīnpiàn jìnxíng yǔyīn kòngzhì xiǎochē de yìngjiàn hé ruǎnjiàn shèjì.
The main topic is the study according to the process control system bender bender analysis and mathematical modeling to determine the suitable control algorithm of the system, the completion of the combination of theory and practice.
Mainly by mechanical bending machine, hydraulic systems, and other components. Mechanical clamping device main unit carriage propulsion, steering wheel swing arm means and the devices and other components.
Its working principle is to use a hydraulic cylinder to promote uniform pipe, steel pipe running along the preset orbit to form a bend radius of curvature and a certain angle. First pipe mounted in place by screw adjustment nut on the actuator arm swing device and good bending radius to obtain the desired pipe bending. Features: bending deformation of the tube with a small wall thickness is small, no stress.
