五金(jin)沖壓件(jian)(jian)(jian)加工所(suo)用(yong)模(mo)具上不(bu)止(zhi)有(you)工藝構件(jian)(jian)(jian),還(huan)得有(you)結構零(ling)(ling)件(jian)(jian)(jian),結構零(ling)(ling)件(jian)(jian)(jian)將模(mo)具上所(suo)有(you)組件(jian)(jian)(jian)組合到(dao)一(yi)起,才能安裝到(dao)壓力機上正常使(shi)用(yong)。這些結構零(ling)(ling)件(jian)(jian)(jian)如下(xia):1、導向零(ling)(ling)件(jian)(jian)(jian)導向零(ling)(ling)件(jian)(jian)(jian)是用(yong)來確定(ding)上下(xia)模(mo)的相對位置,它是保證(zheng)運(yun)動導向精(jing)度(du)的零(ling)(ling)件(jian)(jian)(jian)。例如導柱(zhu)、導套、導板、導筒...
我(wo)們五金沖壓件加(jia)工(gong)廠里拉(la)深(shen)(shen)五金沖壓件通常采用的(de)是一般(ban)(ban)拉(la)深(shen)(shen)工(gong)藝(yi)。所謂的(de)一般(ban)(ban)拉(la)深(shen)(shen)工(gong)藝(yi)指的(de)是不(bu)(bu)變(bian)薄(bo)(bo)拉(la)深(shen)(shen)。但其實拉(la)深(shen)(shen)還有不(bu)(bu)變(bian)薄(bo)(bo)拉(la)深(shen)(shen)工(gong)藝(yi)。下面就簡單介紹下變(bian)薄(bo)(bo)與不(bu)(bu)變(bian)薄(bo)(bo)拉(la)深(shen)(shen)有什么區別。變(bian)薄(bo)(bo)拉(la)深(shen)(shen)與一般(ban)(ban)拉(la)深(shen)(shen)所不(bu)(bu)同(tong)的(de)是:沖壓件在拉(la)深(shen)(shen)過(guo)程中主要(yao)是靠改變(bian)(減(jian)少)...
在五金(jin)沖壓件加工廠(chang),在五金(jin)沖壓件的(de)(de)拉(la)深過程中(zhong)需要使用(yong)潤滑(hua)劑,這是(shi)為什么呢?這是(shi)因為在拉(la)深過程中(zhong),凡是(shi)與毛(mao)坯接觸的(de)(de)模(mo)具表面(mian)上都有(you)摩(mo)(mo)擦(ca)存在。拉(la)深模(mo)的(de)(de)凸緣部分(fen)和凹模(mo)入口(kou)處的(de)(de)摩(mo)(mo)擦(ca)是(shi)有(you)害摩(mo)(mo)擦(ca),它不僅降低了拉(la)深變形(xing)程度,增加了拉(la)深件在危險斷面(mian)處的(de)(de)載荷,...
五金沖(chong)(chong)壓(ya)(ya)件(jian)加工(gong)廠,加工(gong)沖(chong)(chong)壓(ya)(ya)件(jian)的(de)步(bu)就是通過沖(chong)(chong)裁(cai)(cai)來得到沖(chong)(chong)壓(ya)(ya)件(jian)的(de)毛(mao)坯,也(ye)就是我(wo)們常(chang)說(shuo)的(de)下料(liao)(liao)。通過沖(chong)(chong)裁(cai)(cai)下料(liao)(liao)得到的(de)毛(mao)坯我(wo)們稱(cheng)為沖(chong)(chong)裁(cai)(cai)件(jian)。今天來介(jie)紹下沖(chong)(chong)裁(cai)(cai)下料(liao)(liao)時的(de)幾種排樣(yang)方(fang)(fang)式。 沖(chong)(chong)裁(cai)(cai)件(jian)在板料(liao)(liao)或條料(liao)(liao)上的(de)布(bu)置(zhi)方(fang)(fang)法稱(cheng)為...
在汽車所需(xu)(xu)的(de)沖壓件(jian)(jian)(jian)中,有小型(xing)的(de)剎車底板(ban)需(xu)(xu)要拉深(shen),更有大(da)型(xing)的(de)曲(qu)(qu)面制件(jian)(jian)(jian)也用(yong)到(dao)拉深(shen)工藝。今天來和大(da)家分(fen)享下(xia)大(da)型(xing)曲(qu)(qu)面制件(jian)(jian)(jian)的(de)拉深(shen)變形(xing)(xing)特點。 大(da)型(xing)曲(qu)(qu)面制件(jian)(jian)(jian)的(de)變形(xing)(xing)特點是:周邊(bian)為(wei)拉深(shen),內部(bu)則有脹形(xing)(xing)成分(fen)。表面形(xing)(xing)狀(zhuang)...
加工(gong)(gong)五金沖(chong)壓(ya)件(jian)所用的沖(chong)壓(ya)模(mo)具(ju)由(you)工(gong)(gong)藝構(gou)件(jian)和結構(gou)零(ling)件(jian)組成。今天來為(wei)大家介紹下工(gong)(gong)藝構(gou)件(jian)的作用。 沖(chong)壓(ya)模(mo)具(ju)中(zhong)上(shang)工(gong)(gong)藝構(gou)件(jian)包含:工(gong)(gong)作零(ling)件(jian)、定(ding)位零(ling)件(jian)以及(ji)壓(ya)料/卸(xie)料及(ji)出件(jian)零(ling)部件(jian)。下面來了解(jie)下這(zhe)些零(ling)件(jian)在模(mo)具(ju)中(zhong)起(qi)什么作用。 ...
在我們五金(jin)沖壓(ya)件加(jia)工廠(chang)的(de)不變薄(bo)拉(la)(la)深過(guo)程中(zhong),五金(jin)沖壓(ya)件的(de)拉(la)(la)深需(xu)要使用(yong)(粉狀或油狀或乳狀的(de))潤(run)滑(hua)劑(ji)(ji)來(lai)潤(run)滑(hua),那么在變薄(bo)拉(la)(la)深時是采用(yong)哪種(zhong)方法潤(run)滑(hua)的(de)呢(ni)?下面來(lai)簡單了解下。在變薄(bo)拉(la)(la)深時,潤(run)滑(hua)劑(ji)(ji)不僅是為了減少摩(mo)擦,同(tong)時又(you)起到冷卻模具的(de)作用(yong)。因(yin)此不能采用(yong)干...
在五金沖(chong)壓(ya)件加工(gong)廠,沖(chong)壓(ya)件在拉深(shen)過程中的(de)輔助(zhu)工(gong)序(xu)有很多,但大致可歸為(wei)三類:拉深(shen)工(gong)序(xu)前的(de)輔助(zhu)工(gong)序(xu)、拉深(shen)工(gong)序(xu)間的(de)輔助(zhu)工(gong)序(xu)、拉深(shen)后的(de)輔助(zhu)工(gong)序(xu)。下(xia)面來(lai)了解下(xia)。 拉深(shen)前的(de)輔助(zhu)工(gong)序(xu)有:材料的(de)軟化熱(re)處理、清洗、潤滑等...
