一、結構原理(li)

普通半自動氣割機單排氣割時，鋼板直條必然會產生旁彎現象，多頭直條氣割機采用一個門架上安裝多把割炬的方式，使氣割時鋼板直條同時受熱并冷卻，從根本上消除了旁彎現象。
多頭直條數控火焰(yan)切割機主(zhu)(zhu)要(yao)(yao)由(you)∏形(xing)機(ji)架（主(zhu)(zhu)、被動(dong)(dong)驅(qu)(qu)動(dong)(dong)端(duan)(duan)梁(liang)、橫(heng)(heng)(heng)(heng)(heng)梁(liang)）、縱(zong)(zong)向(xiang)(xiang)導(dao)軌(gui)(gui)(gui)（主(zhu)(zhu)、副）、縱(zong)(zong)向(xiang)(xiang)割炬(ju)(ju)、橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)割炬(ju)(ju)、氣體供應系(xi)統以及(ji)電控系(xi)統等組成。主(zhu)(zhu)、被動(dong)(dong)驅(qu)(qu)動(dong)(dong)端(duan)(duan)梁(liang)、橫(heng)(heng)(heng)(heng)(heng)梁(liang)等均采(cai)(cai)用(yong)箱梁(liang)式(shi)(shi)焊接(jie)(jie)結構，焊后再作消除應力處理，其(qi)結構緊(jin)湊，外型美觀(guan)大(da)方。整(zheng)機(ji)的(de)(de)縱(zong)(zong)向(xiang)(xiang)行走采(cai)(cai)用(yong)主(zhu)(zhu)動(dong)(dong)驅(qu)(qu)動(dong)(dong)端(duan)(duan)梁(liang)單邊減(jian)速電機(ji)帶動(dong)(dong)齒(chi)輪齒(chi)條副傳(chuan)動(dong)(dong)的(de)(de)方式(shi)(shi)，其(qi)速度通(tong)(tong)過交(jiao)流變頻器來(lai)調(diao)節。驅(qu)(qu)動(dong)(dong)端(duan)(duan)梁(liang)側裝(zhuang)(zhuang)(zhuang)有(you)水平(ping)(ping)(ping)導(dao)向(xiang)(xiang)輪，可(ke)通(tong)(tong)過調(diao)整(zheng)其(qi)偏心軸使導(dao)向(xiang)(xiang)輪壓(ya)緊(jin)導(dao)軌(gui)(gui)(gui)，從而確保(bao)(bao)整(zheng)機(ji)在(zai)全程運行中(zhong)的(de)(de)平(ping)(ping)(ping)穩和(he)精(jing)度。縱(zong)(zong)向(xiang)(xiang)導(dao)軌(gui)(gui)(gui)（主(zhu)(zhu)、副）均采(cai)(cai)用(yong)高(gao)強(qiang)度路(lu)軌(gui)(gui)(gui)（24Kg/m）制作，路(lu)軌(gui)(gui)(gui)的(de)(de)各接(jie)(jie)觸面(mian)均作精(jing)密機(ji)械加工(gong)，主(zhu)(zhu)導(dao)軌(gui)(gui)(gui)的(de)(de)外側裝(zhuang)(zhuang)(zhuang)有(you)經過精(jing)密磨(mo)加工(gong)的(de)(de)齒(chi)條。主(zhu)(zhu)、副導(dao)軌(gui)(gui)(gui)的(de)(de)固定(ding)通(tong)(tong)過壓(ya)板(ban)(ban)墊板(ban)(ban)和(he)連接(jie)(jie)套來(lai)固定(ding)實現，本(ben)套安(an)裝(zhuang)(zhuang)(zhuang)方式(shi)(shi)可(ke)以確保(bao)(bao)導(dao)軌(gui)(gui)(gui)縱(zong)(zong)向(xiang)(xiang)直線度、平(ping)(ping)(ping)行度等。橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)割炬(ju)(ju)主(zhu)(zhu)要(yao)(yao)用(yong)來(lai)橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)切割板(ban)(ban)條，由(you)橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)割炬(ju)(ju)和(he)橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)拖(tuo)板(ban)(ban)組成，橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)割炬(ju)(ju)安(an)裝(zhuang)(zhuang)(zhuang)在(zai)橫(heng)(heng)(heng)(heng)(heng)向(xiang)(xiang)拖(tuo)板(ban)(ban)上，其(qi)行走通(tong)(tong)過減(jian)速電機(ji)帶動(dong)(dong)齒(chi)輪齒(chi)條副傳(chuan)動(dong)(dong)來(lai)實現。氣體供應采(cai)(cai)用(yong)二次減(jian)壓(ya)，然后分路(lu)供氣的(de)(de)方式(shi)(shi)。防止回火裝(zhuang)(zhuang)(zhuang)置能夠確保(bao)(bao)氣路(lu)的(de)(de)平(ping)(ping)(ping)穩、暢(chang)通(tong)(tong)。
