本實(shi)用新(xin)型涉及一種恒定(ding)基準的管件(jian)自動拉(la)伸裝(zhuang)置。

背景技術：

在銅管(guan)(guan)(guan)的(de)(de)加工過程(cheng)中，先是把(ba)銅材(cai)(cai)料鑄成(cheng)(cheng)銅鑄錠，然(ran)后通過預熱(re)，穿孔及熱(re)壓成(cheng)(cheng)型，接下來是拉(la)伸過程(cheng)，拉(la)伸的(de)(de)強度和(he)次數(shu)根(gen)據加工所需(xu)求的(de)(de)銅管(guan)(guan)(guan)的(de)(de)管(guan)(guan)(guan)徑來決定，現有的(de)(de)銅管(guan)(guan)(guan)的(de)(de)拉(la)伸裝(zhuang)置(zhi)對于銅管(guan)(guan)(guan)的(de)(de)夾持效果不佳，導致(zhi)拉(la)伸精(jing)度不能很好控制，并(bing)且(qie)次品率很高，造成(cheng)(cheng)了(le)銅材(cai)(cai)的(de)(de)浪費，因此(ci)，有必要做進(jin)一步改進(jin)。
