眾所周知，制(zhi)(zhi)作彎(wan)(wan)管(guan)(guan)(guan)(guan)的(de)(de)重要(yao)道具(ju)(ju)彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)是重要(yao)組成部分(fen)，因其不(bu)(bu)同(tong)(tong)的(de)(de)形(xing)狀和(he)(he)形(xing)態(tai)而壓制(zhi)(zhi)出不(bu)(bu)同(tong)(tong)型號和(he)(he)質量的(de)(de)彎(wan)(wan)管(guan)(guan)(guan)(guan)。為節約成本(ben)，通(tong)過不(bu)(bu)同(tong)(tong)的(de)(de)切割工(gong)藝，改(gai)(gai)造出更實用的(de)(de)彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)。在彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)改(gai)(gai)造時，企(qi)業也(ye)要(yao)注意其本(ben)身的(de)(de)特點。彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)夾(jia)緊(jin)部分(fen)不(bu)(bu)能過短，否則容易造成鋼管(guan)(guan)(guan)(guan)變形(xing)，可保(bao)證在20mm左右。在模(mo)(mo)(mo)(mo)具(ju)(ju)管(guan)(guan)(guan)(guan)材(cai)較軟較薄的(de)(de)部位，必須(xu)夾(jia)緊(jin)部分(fen)應穿(chuan)心軸(zhou)防止變形(xing)。對于夾(jia)模(mo)(mo)(mo)(mo)與(yu)(yu)輪(lun)模(mo)(mo)(mo)(mo)是同(tong)(tong)時旋轉彎(wan)(wan)管(guan)(guan)(guan)(guan)的(de)(de)，夾(jia)緊(jin)力不(bu)(bu)需要(yao)太(tai)大(da)(da)。同(tong)(tong)時夾(jia)模(mo)(mo)(mo)(mo)的(de)(de)夾(jia)緊(jin)力可根據管(guan)(guan)(guan)(guan)子(zi)直徑(jing)、管(guan)(guan)(guan)(guan)壁(bi)厚度適當調(diao)整(zheng)(zheng)。用v形(xing)夾(jia)模(mo)(mo)(mo)(mo)夾(jia)緊(jin)時，夾(jia)模(mo)(mo)(mo)(mo)與(yu)(yu)輪(lun)模(mo)(mo)(mo)(mo)有時有間(jian)(jian)隙，間(jian)(jian)隙的(de)(de)大(da)(da)小與(yu)(yu)管(guan)(guan)(guan)(guan)子(zi)直徑(jing)大(da)(da)小有關(guan)，當管(guan)(guan)(guan)(guan)子(zi)直徑(jing)為φ10mm時，間(jian)(jian)隙小。隨著管(guan)(guan)(guan)(guan)子(zi)直徑(jing)的(de)(de)增加(jia)間(jian)(jian)隙逐漸增大(da)(da)，但(dan)不(bu)(bu)影響裝夾(jia)與(yu)(yu)加(jia)工(gong)。如(ru)遇到大(da)(da)于φ18mm管(guan)(guan)(guan)(guan)子(zi)時，要(yao)更換v形(xing)夾(jia)模(mo)(mo)(mo)(mo)、輪(lun)模(mo)(mo)(mo)(mo)與(yu)(yu)導模(mo)(mo)(mo)(mo)。與(yu)(yu)v形(xing)夾(jia)模(mo)(mo)(mo)(mo)不(bu)(bu)同(tong)(tong)，如(ru)用R形(xing)夾(jia)模(mo)(mo)(mo)(mo)裝夾(jia)，夾(jia)模(mo)(mo)(mo)(mo)與(yu)(yu)輪(lun)模(mo)(mo)(mo)(mo)之間(jian)(jian)的(de)(de)間(jian)(jian)隙是沒(mei)有變化的(de)(de)。導模(mo)(mo)(mo)(mo)與(yu)(yu)夾(jia)模(mo)(mo)(mo)(mo)的(de)(de)v形(xing)尺寸應統一(yi)，便(bian)于觀察與(yu)(yu)調(diao)整(zheng)(zheng)彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)。長此以(yi)往，通(tong)過改(gai)(gai)造一(yi)年(nian)大(da)(da)約可節省20種彎(wan)(wan)管(guan)(guan)(guan)(guan)模(mo)(mo)(mo)(mo)具(ju)(ju)的(de)(de)成本(ben)費，而且可**縮短生產時間(jian)(jian)。長期存(cun)(cun)放的(de)(de)彎(wan)(wan)管(guan)(guan)(guan)(guan)，應作按期檢查，常(chang)常(chang)對外露的(de)(de)加(jia)工(gong)表面須(xu)保(bao)持清潔(jie)(jie)，污垢(gou)，整(zheng)(zheng)潔(jie)(jie)地存(cun)(cun)放在室內透風干燥的(de)(de)地方(fang)，嚴禁堆置或露天存(cun)(cun)放。彎(wan)(wan)管(guan)(guan)(guan)(guan)要(yao)常(chang)常(chang)保(bao)持的(de)(de)干燥和(he)(he)透風，保(bao)持器的(de)(de)清潔(jie)(jie)和(he)(he)整(zheng)(zheng)潔(jie)(jie)。阜(fu)陽全(quan)新停車架加(jia)工(gong)批發廠
