1、操作前，先檢查彎管機(jī)各潤滑點(diǎn)是否缺油，運(yùn)動機(jī)構(gòu)是否松動，安全防護(hù)裝置是否可靠，待確認(rèn)后方可操作。2、起動彎管機(jī)油泵，系統(tǒng)壓力是否保持在規(guī)定范圍內(nèi)，若高，損傷液壓元件，浪費(fèi)電源，若過低，影響工作。3、調(diào)整好零件所須位置及所需角度。4、調(diào)整機(jī)件定位至所須長度。5、調(diào)整立式升降導(dǎo)軌，使導(dǎo)模壓緊缸前進(jìn)能夠夾緊緊鐵管。6、調(diào)夾模壓緊缸能夠夾緊鐵管。7、正常操作將工件放入彎曲模內(nèi)，且前端接觸定位，踏下腳踏開關(guān)，即可完成。8、操作彎管機(jī)時，思想要集中，禁止將手或其他物品放入工作區(qū)，如遇緊急情況，按急停按鈕，再將轉(zhuǎn)扭開關(guān)轉(zhuǎn)至手動位置，用手動復(fù)位，若發(fā)生故障，及時報修。9、工作結(jié)束后，切斷電源，做好清潔潤滑工作。帶有自由彎曲系統(tǒng)的彎管機(jī)，除了彎管，還能彎工業(yè)型材，可軸向扭曲。揚(yáng)州彎管機(jī)公司有哪些</p><p
