沖(chong)壓加(jia)工(gong)(gong)(gong)是一種高精(jing)(jing)度加(jia)工(gong)(gong)(gong)，并(bing)且它的(de)(de)加(jia)工(gong)(gong)(gong)效率高，加(jia)工(gong)(gong)(gong)出來五金(jin)(jin)件(jian)具有精(jing)(jing)密，精(jing)(jing)細(xi)，精(jing)(jing)美的(de)(de)特(te)點，成為現在金(jin)(jin)屬加(jia)工(gong)(gong)(gong)的(de)(de)重要工(gong)(gong)(gong)藝。我(wo)們生活中的(de)(de)很多金(jin)(jin)屬物件(jian)都是采(cai)用這種加(jia)工(gong)(gong)(gong)方(fang)(fang)法(fa)來加(jia)來的(de)(de)。那(nei)么這種加(jia)工(gong)(gong)(gong)方(fang)(fang)法(fa)具有哪些加(jia)工(gong)(gong)(gong)原則(ze)呢.
1、精密原則(ze)：拉深(shen)(shen)件(jian)的工(gong)序數(shu)(shu)量(liang)與材(cai)料性(xing)質、拉深(shen)(shen)高度、拉深(shen)(shen)階(jie)梯數(shu)(shu)以及拉深(shen)(shen)直徑(jing)、材(cai)料厚度等條(tiao)件(jian)有關，需(xu)經拉深(shen)(shen)工(gong)藝核算才華承認(ren)。
2、精細原則：彎曲件的(de)工序數(shu)量首要(yao)取(qu)決于其結構形狀(zhuang)的(de)凌亂(luan)程(cheng)度，需根據彎曲角(jiao)的(de)數(shu)目、相對(dui)方位和(he)彎曲方向而定。
3、精美原則：當沖壓加(jia)工(gong)件(jian)的斷面質(zhi)量和(he)標準精度(du)要求較高時，可(ke)以(yi)考慮在沖裁(cai)工(gong)序(xu)(xu)(xu)后再(zai)增加(jia)修整工(gong)序(xu)(xu)(xu)或許直接選用精細沖裁(cai)工(gong)序(xu)(xu)(xu)。
4、精(jing)確原(yuan)則：沖(chong)裁(cai)形狀(zhuang)簡略的(de)工(gong)(gong)(gong)(gong)件(jian)(jian)時(shi)(shi)，選(xuan)用(yong)單工(gong)(gong)(gong)(gong)序(xu)模具結束(shu)即可(ke)，而(er)在沖(chong)裁(cai)形狀(zhuang)凌亂(luan)的(de)工(gong)(gong)(gong)(gong)件(jian)(jian)時(shi)(shi)，由于模具的(de)結構或強度(du)受到(dao)限制，其表里歸納應分紅幾部(bu)分沖(chong)裁(cai)，需選(xuan)用(yong)多道(dao)五金沖(chong)壓(ya)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)。必要時(shi)(shi)，可(ke)選(xuan)用(yong)連續(xu)模。關于平面度(du)要求較(jiao)高的(de)工(gong)(gong)(gong)(gong)件(jian)(jian)，可(ke)在沖(chong)裁(cai)工(gong)(gong)(gong)(gong)序(xu)后(hou)再(zai)增加(jia)一道(dao)校平工(gong)(gong)(gong)(gong)序(xu)，將每種產品的(de)特征精(jing)確到(dao)出(chu)產的(de)工(gong)(gong)(gong)(gong)藝中(zhong)。
5、精(jing)品原則：為了保證(zheng)精(jing)細(xi)五金沖(chong)壓件的質(zhi)量，前進(jin)五金沖(chong)壓加(jia)工工藝的穩定性有時就需要增加(jia)工序數目。如彎(wan)曲件的附加(jia)定位工藝孔(kong)沖(chong)制、成形工藝中(zhong)的增加(jia)變形減輕(qing)孔(kong)沖(chong)裁以轉移變形區等，保證(zheng)每個(ge)產(chan)品做(zuo)到精(jing)細(xi)、精(jing)細(xi)、精(jing)巧的精(jing)品程(cheng)度。
總(zong)結：要(yao)加(jia)工(gong)出精(jing)(jing)美的加(jia)工(gong)件來就要(yao)遵循這五(wu)個原(yuan)則，做(zuo)到(dao)精(jing)(jing)密(mi)，精(jing)(jing)美，精(jing)(jing)確，精(jing)(jing)品(pin)五(wu)大原(yuan)則。
