車(che)床件沖壓的沖模(mo)(mo)方式介紹 沖模(mo)(mo)是沖壓生(sheng)產中(zhong)必不可(ke)少的模(mo)(mo)具。沖模(mo)(mo)基本上(shang)可(ke)分為(wei)簡單模(mo)(mo)、連(lian)續模(mo)(mo)和(he)復合模(mo)(mo)三種。

1、車床(chuang)(chuang)件(jian)(jian)簡(jian)單(dan)沖(chong)(chong)(chong)(chong)模(mo)(mo)(mo) 簡(jian)單(dan)沖(chong)(chong)(chong)(chong)模(mo)(mo)(mo)是(shi)在(zai)沖(chong)(chong)(chong)(chong)床(chuang)(chuang)的一次沖(chong)(chong)(chong)(chong)程中只完(wan)成一個(ge)工序的沖(chong)(chong)(chong)(chong)模(mo)(mo)(mo)。即是(shi)落料(liao)(liao)或沖(chong)(chong)(chong)(chong)孔用的簡(jian)單(dan)沖(chong)(chong)(chong)(chong)模(mo)(mo)(mo)。工作時條(tiao)料(liao)(liao)在(zai)凹模(mo)(mo)(mo)上沿兩個(ge)導板(ban)之間(jian)送進，碰到定(ding)位銷為止(zhi)。凸模(mo)(mo)(mo)向下(xia)(xia)沖(chong)(chong)(chong)(chong)壓時，沖(chong)(chong)(chong)(chong)下(xia)(xia)的零件(jian)(jian)(或廢料(liao)(liao))進入凹模(mo)(mo)(mo)孔，而(er)條(tiao)料(liao)(liao)則夾住(zhu)凸模(mo)(mo)(mo)并(bing)隨凸模(mo)(mo)(mo)一起回程向上運(yun)動。條(tiao)料(liao)(liao)碰到卸料(liao)(liao)板(ban)時(固定(ding)在(zai)凹模(mo)(mo)(mo)上)被推下(xia)(xia)，這樣(yang)，條(tiao)料(liao)(liao)繼續在(zai)導板(ban)間(jian)送進。重復上述動作，沖(chong)(chong)(chong)(chong)下(xia)(xia)第二(er)個(ge)零件(jian)(jian)。

2、車(che)床(chuang)件連續沖(chong)(chong)(chong)模(mo)(mo)(mo)(mo) 沖(chong)(chong)(chong)床(chuang)的(de)一次沖(chong)(chong)(chong)程中(zhong)，在模(mo)(mo)(mo)(mo)具不同部位(wei)上(shang)(shang)(shang)同時完成數道沖(chong)(chong)(chong)壓工(gong)(gong)序(xu)的(de)模(mo)(mo)(mo)(mo)具，稱為連續模(mo)(mo)(mo)(mo)。工(gong)(gong)作時定位(wei)銷對準(zhun)預先沖(chong)(chong)(chong)出的(de)定位(wei)孔，上(shang)(shang)(shang)模(mo)(mo)(mo)(mo)向下運動，凸模(mo)(mo)(mo)(mo)進(jin)(jin)(jin)行(xing)落料(liao)，凸模(mo)(mo)(mo)(mo)進(jin)(jin)(jin)行(xing)沖(chong)(chong)(chong)孔。當上(shang)(shang)(shang)模(mo)(mo)(mo)(mo)回程時，卸料(liao)板從凸模(mo)(mo)(mo)(mo)上(shang)(shang)(shang)推(tui)下廢料(liao)。這時再將坯料(liao)向前送(song)進(jin)(jin)(jin)，執行(xing)第二次沖(chong)(chong)(chong)裁。如此循(xun)環進(jin)(jin)(jin)行(xing)，每(mei)次送(song)進(jin)(jin)(jin)距離(li)由(you)擋料(liao)銷控制。

3、車床件(jian)復(fu)合(he)沖模(mo)(mo)(mo)(mo)(mo) 在一次沖程(cheng)中(zhong)(zhong)，在模(mo)(mo)(mo)(mo)(mo)具(ju)同一部(bu)位(wei)上同時(shi)完(wan)成(cheng)數道沖壓工序的(de)(de)模(mo)(mo)(mo)(mo)(mo)具(ju)，稱為復(fu)合(he)模(mo)(mo)(mo)(mo)(mo)。復(fu)合(he)模(mo)(mo)(mo)(mo)(mo)的(de)(de)最大特點是模(mo)(mo)(mo)(mo)(mo)具(ju)中(zhong)(zhong)有一個(ge)凸(tu)凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)。凸(tu)凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)的(de)(de)外圓是落料凸(tu)模(mo)(mo)(mo)(mo)(mo)刃口，內孔(kong)則成(cheng)為拉(la)(la)深凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)。當(dang)(dang)滑(hua)塊(kuai)帶著凸(tu)凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)向(xiang)(xiang)下(xia)運動時(shi)，條料首先在凸(tu)凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)1和落料凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)中(zhong)(zhong)落料。落料件(jian)被下(xia)模(mo)(mo)(mo)(mo)(mo)當(dang)(dang)中(zhong)(zhong)的(de)(de)拉(la)(la)深凸(tu)模(mo)(mo)(mo)(mo)(mo)頂(ding)住，滑(hua)塊(kuai)繼續向(xiang)(xiang)下(xia)運動時(shi)，凹(ao)(ao)模(mo)(mo)(mo)(mo)(mo)隨之向(xiang)(xiang)下(xia)運動進行拉(la)(la)深。頂(ding)出(chu)器(qi)(qi)和卸料器(qi)(qi)在滑(hua)塊(kuai)的(de)(de)回程(cheng)中(zhong)(zhong)將拉(la)(la)深件(jian)推(tui)出(chu)模(mo)(mo)(mo)(mo)(mo)具(ju)。復(fu)合(he)模(mo)(mo)(mo)(mo)(mo)適用(yong)于產量(liang)大、精度(du)高的(de)(de)沖壓件(jian)。
