沖壓(ya)(ya)件生(sheng)產過(guo)程中開(kai)(kai)裂(lie)(lie)的原因？沖壓(ya)(ya)過(guo)程常遇到沖壓(ya)(ya)板件開(kai)(kai)裂(lie)(lie)，影響制(zhi)件質量(liang)，制(zhi)約生(sheng)產效率，如何消除沖壓(ya)(ya)件開(kai)(kai)裂(lie)(lie)需要從(cong)以下幾個方面(mian)分析原因。1、機床(chuang)(chuang)壓(ya)(ya)力過(guo)大(da)(da)(da)，導致沖壓(ya)(ya)件開(kai)(kai)裂(lie)(lie)。2、機床(chuang)(chuang)頂桿(gan)高度(du)不(bu)一(yi)致，導致壓(ya)(ya)邊圈受力不(bu)均勻，致使沖壓(ya)(ya)件開(kai)(kai)裂(lie)(lie)。3、模具(ju)型面(mian)研(yan)合率著色不(bu)均勻，硬點太多。4、沖壓(ya)(ya)件生(sheng)產過(guo)程中開(kai)(kai)裂(lie)(lie)的原因，模具(ju)型面(mian)光(guang)潔度(du)差，R角(jiao)不(bu)光(guang)順，模具(ju)型面(mian)粗糙(cao)，未推光(guang)處(chu)理(li)。5、上模拉延筋過(guo)高，阻力大(da)(da)(da)，料(liao)(liao)(liao)無(wu)法流動造(zao)成(cheng)開(kai)(kai)裂(lie)(lie)；6、板料(liao)(liao)(liao)臟，有異(yi)物造(zao)成(cheng)，造(zao)成(cheng)開(kai)(kai)裂(lie)(lie)，應清擦板料(liao)(liao)(liao)、擦拭模具(ju)保持(chi)清潔。沖壓(ya)(ya)件特(te)點：沖壓(ya)(ya)件是在材料(liao)(liao)(liao)消耗不(bu)大(da)(da)(da)的前提下，經(jing)沖壓(ya)(ya)制(zhi)造(zao)出來的。天津SUS316沖壓(ya)(ya)件供應商(shang)
