沖(chong)床(chuang)廠介紹(shao)沖(chong)床(chuang)模(mo)(mo)(mo)具(ju)安(an)裝使(shi)(shi)用(yong)不當的(de)話不但(dan)會影響產品加(jia)工質量，還會影響模(mo)(mo)(mo)具(ju)本身的(de)使(shi)(shi)用(yong)壽命，增(zeng)加(jia)成本，因(yin)此，我(wo)們應該正確的(de)安(an)裝使(shi)(shi)用(yong)模(mo)(mo)(mo)具(ju)，怎么正確的(de)使(shi)(shi)用(yong)沖(chong)床(chuang)廠介紹(shao)沖(chong)床(chuang)模(mo)(mo)(mo)具(ju)，山(shan)東南(nan)皮(pi)威力沖(chong)床(chuang)廠介紹(shao)沖(chong)床(chuang)廠指導你。

1、保(bao)證最佳(jia)的(de)(de)(de)(de)(de)模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi) 模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi)是指沖頭(tou)進(jin)入下模(mo)(mo)中，兩(liang)側的(de)(de)(de)(de)(de)間(jian)隙(xi)(xi)(xi)之和(he)。模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi)的(de)(de)(de)(de)(de)選擇取(qu)決于板厚、材質(zhi)以及(ji)沖壓工藝(yi)等，不同(tong)板厚或者(zhe)材質(zhi)應選用相應的(de)(de)(de)(de)(de)模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi)，間(jian)隙(xi)(xi)(xi)過小或者(zhe)過大或者(zhe)損壞模(mo)(mo)具(ju)(ju)或者(zhe)影響沖孔(kong)質(zhi)量。如果(guo)模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi)選用的(de)(de)(de)(de)(de)合適(shi)，就能夠保(bao)證良好的(de)(de)(de)(de)(de)沖孔(kong)質(zhi)量，毛刺和(he)塌陷減少，保(bao)持板料(liao)(liao)(liao)平(ping)整，有效(xiao)防止(zhi)帶料(liao)(liao)(liao)，延長模(mo)(mo)具(ju)(ju)使用壽(shou)命。模(mo)(mo)具(ju)(ju)間(jian)隙(xi)(xi)(xi)的(de)(de)(de)(de)(de)判定主(zhu)要通(tong)過檢(jian)查沖壓廢料(liao)(liao)(liao)的(de)(de)(de)(de)(de)情況的(de)(de)(de)(de)(de)辦(ban)法。廢料(liao)(liao)(liao)如果(guo)出現(xian)(xian)粗(cu)糙起伏的(de)(de)(de)(de)(de)斷裂(lie)面(mian)和(he)較小的(de)(de)(de)(de)(de)光亮面(mian)，就說明(ming)間(jian)隙(xi)(xi)(xi)過大。斷裂(lie)面(mian)與光亮面(mian)形成的(de)(de)(de)(de)(de)角度(du)與間(jian)隙(xi)(xi)(xi)成正向比。間(jian)隙(xi)(xi)(xi)越大，隙(xi)(xi)(xi)沖孔(kong)時會形成卷邊(bian)和(he)斷裂(lie)，甚至出現(xian)(xian)一個(ge)薄(bo)緣突起。

2、消除和(he)減少(shao)粘料的方法 由(you)于沖壓時(shi)會產生(sheng)(sheng)壓力和(he)熱量，板料的細小顆粒就會粘結(jie)在沖頭表(biao)面(mian)(mian)上(shang)，從而影響沖件的質量。一般采用(yong)(yong)潤滑的方式(shi)防(fang)止過熱，同時(shi)也會減少(shao)摩(mo)擦。如果無法潤滑或出現廢(fei)料回彈等情(qing)況，可(ke)(ke)采取交(jiao)替使(shi)用(yong)(yong)同尺寸沖頭沖壓的辦法，多個沖頭輪(lun)流沖壓可(ke)(ke)使(shi)每個沖頭在使(shi)用(yong)(yong)之前有較充足的冷卻時(shi)間。要(yao)去除沖頭上(shang)的粘料可(ke)(ke)用(yong)(yong)細油石進行打(da)磨，避免進一步粘料的產生(sheng)(sheng)打(da)磨方向應與沖頭運(yun)動的方向應保(bao)持一致。要(yao)避免使(shi)用(yong)(yong)粗紗布進行打(da)磨，防(fang)止沖頭表(biao)面(mian)(mian)變得更加粗糙，粘料現象再次(ci)發生(sheng)(sheng)。

3、沖(chong)(chong)(chong)(chong)很(hen)(hen)多(duo)孔(kong)時防(fang)止(zhi)板(ban)(ban)料變(bian)(bian)(bian)形(xing)的(de)(de)措施(shi) 如果在一張板(ban)(ban)上沖(chong)(chong)(chong)(chong)很(hen)(hen)多(duo)孔(kong)，板(ban)(ban)材就(jiu)會(hui)出現變(bian)(bian)(bian)形(xing)現象(xiang)。這(zhe)是(shi)由于(yu)每次沖(chong)(chong)(chong)(chong)孔(kong)時，由于(yu)沖(chong)(chong)(chong)(chong)切(qie)應(ying)(ying)力(li)(li)的(de)(de)積(ji)累，孔(kong)周邊的(de)(de)材料會(hui)向下(xia)(xia)變(bian)(bian)(bian)形(xing)，板(ban)(ban)料上表面(mian)出現拉(la)應(ying)(ying)力(li)(li)，而(er)下(xia)(xia)表面(mian)則出現壓(ya)應(ying)(ying)力(li)(li)。當(dang)沖(chong)(chong)(chong)(chong)很(hen)(hen)少的(de)(de)孔(kong)時候(hou)，這(zhe)種重切(qie)應(ying)(ying)力(li)(li)不(bu)(bu)會(hui)影(ying)響板(ban)(ban)材的(de)(de)質(zhi)量，但當(dang)沖(chong)(chong)(chong)(chong)很(hen)(hen)多(duo)的(de)(de)孔(kong)時，板(ban)(ban)料上下(xia)(xia)表面(mian)的(de)(de)拉(la)應(ying)(ying)力(li)(li)和壓(ya)應(ying)(ying)力(li)(li)在某點上不(bu)(bu)斷積(ji)累，就(jiu)會(hui)致使材料不(bu)(bu)平(ping)整、變(bian)(bian)(bian)形(xing)。防(fang)止(zhi)此類變(bian)(bian)(bian)形(xing)的(de)(de)方法是(shi):改(gai)變(bian)(bian)(bian)孔(kong)的(de)(de)沖(chong)(chong)(chong)(chong)切(qie)順(shun)序，隔(ge)孔(kong)沖(chong)(chong)(chong)(chong)切(qie)，然后(hou)返回沖(chong)(chong)(chong)(chong)切(qie)剩(sheng)余的(de)(de)孔(kong)。這(zhe)樣能夠有效(xiao)的(de)(de)降低在同(tong)一方向順(shun)序沖(chong)(chong)(chong)(chong)壓(ya)時的(de)(de)應(ying)(ying)力(li)(li)累積(ji)，雖然這(zhe)種沖(chong)(chong)(chong)(chong)切(qie)方法也會(hui)產生應(ying)(ying)力(li)(li)，但是(shi)它會(hui)相互(hu)抵消(xiao)前后(hou)兩組孔(kong)的(de)(de)應(ying)(ying)力(li)(li)，從而(er)防(fang)止(zhi)了板(ban)(ban)料的(de)(de)變(bian)(bian)(bian)形(xing)。

4、盡(jin)量(liang)避免(mian)沖(chong)(chong)切過窄(zhai)條料(liao) 當模具(ju)用于(yu)沖(chong)(chong)切寬度(du)小(xiao)(xiao)于(yu)板(ban)(ban)(ban)材厚(hou)度(du)的(de)(de)(de)板(ban)(ban)(ban)料(liao)時(shi)，沖(chong)(chong)頭會(hui)由(you)于(yu)側向力作(zuo)用而彎曲變(bian)形，而令一側，由(you)于(yu)間隙過小(xiao)(xiao)會(hui)使(shi)磨(mo)損加劇(ju)，嚴(yan)重時(shi)會(hui)使(shi)下模刮傷，或(huo)者同時(shi)使(shi)上下模損壞。另外，剪切過窄(zhai)條料(liao)時(shi)，板(ban)(ban)(ban)料(liao)往(wang)往(wang)不會(hui)被完全剪掉，而是會(hui)傾向彎入(ru)下模開口中(zhong)，甚至會(hui)楔入(ru)沖(chong)(chong)模的(de)(de)(de)側面。避免(mian)這種(zhong)磨(mo)具(ju)磨(mo)損的(de)(de)(de)辦(ban)法是，盡(jin)量(liang)避免(mian)步沖(chong)(chong)寬度(du)過小(xiao)(xiao)的(de)(de)(de)窄(zhai)條板(ban)(ban)(ban)料(liao)，特別是小(xiao)(xiao)于(yu)5倍(bei)板(ban)(ban)(ban)材厚(hou)度(du)的(de)(de)(de)板(ban)(ban)(ban)料(liao)；如果無法避免(mian)窄(zhai)料(liao)沖(chong)(chong)切，建議使(shi)用退(tui)料(liao)板(ban)(ban)(ban)或(huo)者使(shi)用全導向模具(ju)。
