五(wu)金(jin)沖(chong)(chong)(chong)壓(ya)(ya)件(jian)(jian)廣泛的(de)(de)應用(yong)(yong)于我(wo)們生活當中的(de)(de)各(ge)個(ge)領域，包括(kuo)一(yi)些電子器件(jian)(jian)、汽(qi)車(che)配件(jian)(jian)、裝飾材料(liao)等等。我(wo)們通(tong)常(chang)(chang)說的(de)(de)沖(chong)(chong)(chong)壓(ya)(ya)件(jian)(jian)一(yi)般是指的(de)(de)是冷沖(chong)(chong)(chong)壓(ya)(ya)零件(jian)(jian)。五(wu)金(jin)沖(chong)(chong)(chong)壓(ya)(ya)件(jian)(jian)常(chang)(chang)用(yong)(yong)的(de)(de)一(yi)些設備？剪板機(ji)(ji)、數控沖(chong)(chong)(chong)床、激光、等離子、水(shui)射流切割機(ji)(ji)、復合機(ji)(ji)、折彎機(ji)(ji)以及各(ge)種(zhong)輔助設備如(ru)：開卷(juan)機(ji)(ji)、校平機(ji)(ji)、去毛刺機(ji)(ji)、點焊(han)機(ji)(ji)等。沖(chong)(chong)(chong)壓(ya)(ya)件(jian)(jian)主要選用(yong)(yong)不(bu)同硬(ying)度不(bu)銹鋼，合金(jin)鋼，汽(qi)車(che)車(che)身結構(gou)件(jian)(jian)加工，鋁，硬(ying)金(jin)屬，銅，鐵制(zhi)造出各(ge)種(zhong)形狀(zhuang)不(bu)同尺寸不(bu)同用(yong)(yong)途的(de)(de)生活用(yong)(yong)品(pin)，機(ji)(ji)械部件(jian)(jian)，用(yong)(yong)途廣泛，已經成為推(tui)動(dong)社會發展的(de)(de)重要因素之一(yi)。

卷料常見的不良現象主(zhu)要有以下方面：

1、鋼板表面或者內部有異物(wu)混入;

2、異物(wu)剝落，阜陽汽車車身加工，卷料呈傷疤一樣的狀(zhuang)態; 卷料不良(liang)

3、卷料邊角破損;

4、邊角(20～30mm)由于應力不(bu)均勻(yun)而發(fa)生(sheng)變形或者壓皺;

5、刮痕(hen)(輥子表面或者異物質引起);

6、輥子滑動引起;

7、邊緣不規則破損;

8、異物進入后在卷(juan)料(liao)背(bei)面(mian)壓出鼓包(異物掉下(xia)則消失);

9、輥(gun)子痕跡(異物附著在輥(gun)子上引起);

10、超出規(gui)則以外(wai)的材質不良;

沖(chong)(chong)(chong)壓(ya)件是借(jie)助于(yu)常規(gui)或(huo)專i用沖(chong)(chong)(chong)壓(ya)設備(bei)的(de)動力，使板料在(zai)模具里直接(jie)受到(dao)變形(xing)力并進(jin)行變形(xing)，汽車車身加(jia)工(gong)(gong)(gong)價(jia)格，從而獲得一(yi)定(ding)形(xing)狀(zhuang)，尺寸和性能的(de)產品零件的(de)生(sheng)產技術。板料，模具和設備(bei)是沖(chong)(chong)(chong)壓(ya)加(jia)工(gong)(gong)(gong)的(de)三要素。沖(chong)(chong)(chong)壓(ya)加(jia)工(gong)(gong)(gong)是一(yi)種金(jin)屬冷變形(xing)加(jia)工(gong)(gong)(gong)方(fang)法。所以，被稱(cheng)(cheng)之(zhi)(zhi)為冷沖(chong)(chong)(chong)壓(ya)或(huo)板料沖(chong)(chong)(chong)壓(ya)，簡稱(cheng)(cheng)沖(chong)(chong)(chong)壓(ya)。它是金(jin)屬塑(su)性加(jia)工(gong)(gong)(gong)（或(huo)壓(ya)力加(jia)工(gong)(gong)(gong)）的(de)主要方(fang)法之(zhi)(zhi)一(yi)，也隸(li)屬于(yu)材料成型工(gong)(gong)(gong)程技術。
