產品描述

⑴.合理的(de)(de)(de)模(mo)具(ju)設(she)計。在級進模(mo)中,下(xia)(xia)料(liao)(liao)(liao)(liao)(liao)順序的(de)(de)(de)安(an)排有(you)可(ke)能(neng)影(ying)響到(dao)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)成(cheng)(cheng)形(xing)的(de)(de)(de)精度。針(zhen)對沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)細小(xiao)部(bu)位的(de)(de)(de)下(xia)(xia)料(liao)(liao)(liao)(liao)(liao),一般先安(an)排較大(da)面積之沖(chong)(chong)切(qie)下(xia)(xia)料(liao)(liao)(liao)(liao)(liao),再(zai)安(an)排較小(xiao)面積的(de)(de)(de)沖(chong)(chong)切(qie)下(xia)(xia)料(liao)(liao)(liao)(liao)(liao),以減(jian)輕(qing)沖(chong)(chong)裁(cai)力(li)(li)對沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)成(cheng)(cheng)形(xing)的(de)(de)(de)影(ying)響。⑵.壓(ya)(ya)(ya)(ya)(ya)(ya)住材料(liao)(liao)(liao)(liao)(liao)。克服傳統(tong)的(de)(de)(de)模(mo)具(ju)設(she)計結(jie)構,在卸料(liao)(liao)(liao)(liao)(liao)板上開出容料(liao)(liao)(liao)(liao)(liao)間(jian)隙(即(ji)模(mo)具(ju)閉(bi)合時,而(er)(er)材料(liao)(liao)(liao)(liao)(liao)又可(ke)被壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)。關鍵成(cheng)(cheng)形(xing)部(bu)位,卸料(liao)(liao)(liao)(liao)(liao)板   做成(cheng)(cheng)鑲(xiang)塊(kuai)式結(jie)構,以方便解決長時間(jian)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)所(suo)導(dao)致卸料(liao)(liao)(liao)(liao)(liao)板壓(ya)(ya)(ya)(ya)(ya)(ya)料(liao)(liao)(liao)(liao)(liao)部(bu)位產生(sheng)的(de)(de)(de)磨(壓(ya)(ya)(ya)(ya)(ya)(ya))損,而(er)(er)無(wu)法壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)材料(liao)(liao)(liao)(liao)(liao)。⑶.增(zeng)設(she)強壓(ya)(ya)(ya)(ya)(ya)(ya)功(gong)能(neng)。即(ji)對卸料(liao)(liao)(liao)(liao)(liao)鑲(xiang)塊(kuai)壓(ya)(ya)(ya)(ya)(ya)(ya)料(liao)(liao)(liao)(liao)(liao)部(bu)加(jia)厚(hou)尺寸(cun)(正常的(de)(de)(de)卸料(liao)(liao)(liao)(liao)(liao)鑲(xiang)塊(kuai)厚(hou)H+0.03mm),以增(zeng)加(jia)對凹(ao)(ao)模(mo)側材料(liao)(liao)(liao)(liao)(liao)的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li),從而(er)(er)抑(yi)(yi)制沖(chong)(chong)切(qie)時沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)產生(sheng)翻(fan)料(liao)(liao)(liao)(liao)(liao)、扭(niu)(niu)曲變(bian)形(xing)。⑷.凸(tu)模(mo)刃口端部(bu)修出斜面或弧形(xing)。這是減(jian)緩(huan)沖(chong)(chong)裁(cai)力(li)(li)的(de)(de)(de)有(you)效方法。減(jian)緩(huan)沖(chong)(chong)裁(cai)力(li)(li),即(ji)可(ke)減(jian)輕(qing)對凹(ao)(ao)模(mo)側材料(liao)(liao)(liao)(liao)(liao)的(de)(de)(de)拉(la)伸力(li)(li),從而(er)(er)達到(dao)抑(yi)(yi)制沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)產生(sheng)翻(fan)料(liao)(liao)(liao)(liao)(liao)、扭(niu)(niu)曲的(de)(de)(de)效果。⑸.日常模(mo)具(ju)生(sheng)產中,應注意維(wei)護沖(chong)(chong)切(qie)凸(tu)、凹(ao)(ao)模(mo)刃口的(de)(de)(de)鋒(feng)利度。當沖(chong)(chong)切(qie)刃口磨損時,材料(liao)(liao)(liao)(liao)(liao)所(suo)受(shou)拉(la)應力(li)(li)將增(zeng)大(da),從而(er)(er)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)(ya)件(jian)(jian)產生(sheng)翻(fan)料(liao)(liao)(liao)(liao)(liao)、扭(niu)(niu)曲的(de)(de)(de)趨向加(jia)大(da)。
