13、棒料切割機(jī)電一體化系統(tǒng)主要由四個部分組成：機(jī)械本體、電子控制單元、執(zhí)行器和動力源。工作原理是電動機(jī)通過帶傳動帶動切割片做高速旋轉(zhuǎn)運動，電機(jī)與工作臺之間采用鉸支撐方式，升降液壓缸可推動切割片進(jìn)行上下移動帶動刀片完成順序切割動作。切割機(jī)采用 PLC 控制各個液壓換向閥的電磁鐵，實現(xiàn)棒料的自動下料和切割以及檢測工作。隨動工作臺前進(jìn)速度也可以通過夾緊機(jī)械手夾緊棒料使之與棒料速度同步。橫向切割時的切割速度可以通過液壓缸來調(diào)節(jié)?，F(xiàn)場運行情況表明，此

14、切割機(jī)具有動作快、運動平穩(wěn)以及與計算機(jī)聯(lián)機(jī)方便等優(yōu)點，能夠降低工人的勞動強(qiáng)度，實現(xiàn)自動控制，提高勞動生產(chǎn)率。關(guān)鍵詞：切割機(jī)；機(jī)電一體化；液壓；棒料；PLC 控制Design of Bar Cutting MachineStudent majoring in mechanical and electronic engineering Name Wei ZhongshuangTutor Yan Bingjie Abstract：Bas
