托輥架是帶式輸送機主zhu要yao部bu件jian，而er邊bian支zhi柱zhu是shi托tuo輥gun架jia的de主zhu要yao零ling件jian。隨sui著zhe大da功gong率lv寬kuan型xing皮pi帶dai機ji的de不bu斷duan應ying用yong，邊bian支zhi柱zhu的de外wai形xing尺chi寸cun包bao括kuo邊bian支zhi柱zhu的de立li麵mian也ye不bu斷duan加jia大da。當dang邊bian支zhi柱zhu尺chi寸cun加jia大da時shi使shi用yong液ye壓ya壓ya力li機ji加jia工gong可ke以yi減jian小xiao衝chong壓ya件jian的de變bian形xing速su率lv，但dan是shi由you於yu邊bian支zhi柱zhu的de立li麵mian過guo於yu加jia大da，超出了材料的變形極限，發生部分斷裂，而且液壓壓力機工作效率較低，在大批量生產衝壓件時並不適用。而使用衝床可以提高加工效率，但是由於使材料在短時間發生較大變形，所以多數工件都發生材料的脆斷。如何使用現有的衝床設備，以較快的加工速度，而使工件邊緣不發生斷裂，仍能達到托輥架的使用功能呢？經過現場分析和實踐，發現使用預熱法可以較好達到這一預想。
