數控(kong)相貫線切割機多少錢哪家好
發布時間:2020-05-29 19:58:01數控相貫(guan)線切割(ge)機是一種對(dui)鋼管與有色金(jin)(jin)屬管子的結(jie)合處相貫線孔、相貫線端部、彎頭(蝦米節)進行(xing)自動(dong)計(ji)算和切(qie)割的設備。該機廣(guang)泛運用(yong)于建筑(zhu)、化工(gong)(gong)、造船、機械工(gong)(gong)程(cheng)、冶金(jin)(jin)、電力等行(xing)業的管道結(jie)構件的切(qie)割加工(gong)(gong)。此類加工(gong)(gong)以往大(da)多(duo)采用(yong)制作樣(yang)板、劃(hua)線、人工(gong)(gong)放(fang)樣(yang)、手(shou)工(gong)(gong)切(qie)割、人工(gong)(gong)打磨等落后繁復操作工(gong)(gong)藝(yi)。
YC-XGX數控管(guan)道(dao)相貫線切(qie)割(ge)(ge)(ge)機主(zhu)要(yao)由控制系(xi)(xi)統(tong)(tong)(tong)、機臂系(xi)(xi)統(tong)(tong)(tong)、驅動裝置(zhi)、裝夾裝置(zhi)、支撐裝置(zhi)、導軌、氣(qi)路系(xi)(xi)統(tong)(tong)(tong)、控制柜、操作(zuo)臺(tai)等部分組成。 配備(bei)火(huo)焰(yan)切(qie)割(ge)(ge)(ge)系(xi)(xi)統(tong)(tong)(tong)一套(含預熱(re)部分),作(zuo)為(wei)主(zhu)要(yao)切(qie)割(ge)(ge)(ge)系(xi)(xi)統(tong)(tong)(tong)。如果用戶(hu)需要(yao)切(qie)割(ge)(ge)(ge)不銹鋼材(cai)料和有色金屬材(cai)料的管(guan)子(zi),本機器可配備(bei)空氣(qi)等離子(zi)切(qie)割(ge)(ge)(ge)系(xi)(xi)統(tong)(tong)(tong),作(zuo)為(wei)主(zhu)要(yao)切(qie)割(ge)(ge)(ge)系(xi)(xi)統(tong)(tong)(tong)或(huo)作(zuo)為(wei)輔助切(qie)割(ge)(ge)(ge)系(xi)(xi)統(tong)(tong)(tong)。相貫線切(qie)割(ge)(ge)(ge)機的特(te)特(te)點有一下幾點:
1、在旋轉(zhuan)卡盤部分,采用滾輪結(jie)構,保(bao)證卡盤在夾緊工(gong)件的同時,使工(gong)件能(neng)順暢(chang)地進行縱向移動。
2、在(zai)送進卡(ka)盤(pan)(pan)(pan)部分采用了(le)浮動(dong)夾(jia)緊系統(tong),可以補償工件中(zhong)心軸線的偏(pian)差。即使管件有(you)較(jiao)大不一(yi)致(zhi)性仍能獲(huo)得(de)較(jiao)好(hao)的精度。在(zai)工件進行高速旋轉(zhuan)時,可互控以有(you)效的避(bi)免卡(ka)盤(pan)(pan)(pan)所(suo)承受的機(ji)械應(ying)(ying)力(li)。因為鋼管在(zai)出廠(chang)時就允許有(you)一(yi)定的偏(pian)差,如壁(bi)厚偏(pian)差和彎曲度偏(pian)差。這(zhe)些在(zai)旋轉(zhuan)時均會對卡(ka)盤(pan)(pan)(pan)產(chan)生相(xiang)應(ying)(ying)的機(ji)械應(ying)(ying)力(li)。
3、相貫(guan)線切割機由于兩個卡盤(pan)同軸,這使工件在夾緊后(hou)左右兩端(duan)自動(dong)處(chu)于同一(yi)軸線(xian)(xian)上,這就解(jie)決(jue)了裝夾鋼(gang)管所(suo)造(zao)成的(de)(de)(de)(de)誤(wu)差。在鋼(gang)管旋(xuan)(xuan)轉時,由于旋(xuan)(xuan)轉卡盤(pan)夾住鋼(gang)管,對其施加了限制,使鋼(gang)管在此處(chu)和卡盤(pan)的(de)(de)(de)(de)中心軸線(xian)(xian)重合,因而(er)極大的(de)(de)(de)(de)改(gai)善鋼(gang)管旋(xuan)(xuan)轉時在切割部位(wei)的(de)(de)(de)(de)跳動(dong)問題。并且(qie)割炬主(zhu)要(yao)在旋(xuan)(xuan)轉卡盤(pan)附近進行切割,從而(er)容易獲得準確的(de)(de)(de)(de)相貫線(xian)(xian)軌跡。
4、采用雙移(yi)動(dong)(dong)系統,即送(song)進(jin)(jin)(jin)卡(ka)盤可在(zai)(zai)床身進(jin)(jin)(jin)行(xing)左(zuo)(zuo)右(you)(you)移(yi)動(dong)(dong),同時割(ge)(ge)炬也(ye)可以進(jin)(jin)(jin)行(xing)左(zuo)(zuo)右(you)(you)移(yi)動(dong)(dong)。送(song)進(jin)(jin)(jin)卡(ka)盤的(de)(de)(de)左(zuo)(zuo)右(you)(you)移(yi)動(dong)(dong)主(zhu)要(yao)是(shi)對(dui)鋼管(guan)(guan)進(jin)(jin)(jin)行(xing)送(song)進(jin)(jin)(jin)長(chang)度(du)方向(xiang)上定位,而(er)(er)(er)割(ge)(ge)炬的(de)(de)(de)左(zuo)(zuo)右(you)(you)移(yi)動(dong)(dong)是(shi)在(zai)(zai)進(jin)(jin)(jin)行(xing)切(qie)(qie)割(ge)(ge)時,與旋轉卡(ka)盤的(de)(de)(de)旋轉運(yun)動(dong)(dong)相配合實現相貫(guan)線軌跡的(de)(de)(de)切(qie)(qie)割(ge)(ge)。此時卡(ka)盤只需完(wan)(wan)(wan)成(cheng)(cheng)相對(dui)簡單的(de)(de)(de)回轉運(yun)動(dong)(dong),可有效的(de)(de)(de)提(ti)高切(qie)(qie)割(ge)(ge)精度(du)和(he)(he)速度(du)。如果割(ge)(ge)炬不進(jin)(jin)(jin)行(xing)左(zuo)(zuo)右(you)(you)移(yi)動(dong)(dong),則運(yun)動(dong)(dong)全都由卡(ka)盤送(song)進(jin)(jin)(jin)完(wan)(wan)(wan)成(cheng)(cheng),這樣需要(yao)不斷對(dui)鋼管(guan)(guan)進(jin)(jin)(jin)行(xing)送(song)進(jin)(jin)(jin)和(he)(he)退回運(yun)動(dong)(dong),以完(wan)(wan)(wan)成(cheng)(cheng)相貫(guan)軌跡的(de)(de)(de)切(qie)(qie)割(ge)(ge)。這時鋼管(guan)(guan)時而(er)(er)(er)受(shou)壓,時而(er)(er)(er)受(shou)拉(la),會對(dui)鋼管(guan)(guan)產生額外的(de)(de)(de)附(fu)加力,造成(cheng)(cheng)切(qie)(qie)割(ge)(ge)軌跡的(de)(de)(de)不準確。
