钣金冲(chong)压工艺适(shi)用(yong)(yong)于静音柜、配电柜等柜体结构冲(chong)孔、落料、抹角(jiao)之用(yong)(yong)。冲(chong)床：应根(gen)据工件的冲(chong)裁力来(lai)选择不同(tong)吨位(wei)的冲(chong)床，使(shi)用(yong)(yong)的模具需经检(jian)验合格后方可(ke)使(shi)用(yong)(yong)。

钣金加工表面

严格执行(xing)(xing)首件(jian)(jian)检(jian)(jian)查(cha)(cha)、中(zhong)间抽查(cha)(cha)、尾(wei)件(jian)(jian)复查(cha)(cha)；工件(jian)(jian)加工尺寸(cun)按(an)图纸或(huo)工艺文件(jian)(jian)进行(xing)(xing)检(jian)(jian)查(cha)(cha)；冲孔边(bian)缘不(bu)(bu)应有拉(la)伸、弯曲(qu)，毛刺高度不(bu)(bu)大于料厚的(de)10%——15%；

钣金加工表面处理

试车检查(cha)机械、电(dian)气(qi)性能的安全可靠性；需加(jia)(jia)工(gong)的零件应(ying)经上(shang)(shang)道工(gong)序检验(yan)合格后方可加(jia)(jia)工(gong)； 加(jia)(jia)工(gong)前要(yao)明确(que)技术(shu)要(yao)求，核(he)对来料有无差错；了解到根据加(jia)(jia)工(gong)要(yao)求选择相应(ying)模(mo)具；先将(jiang)冲(chong)床滑块(kuai)(kuai)点(dian)到上(shang)(shang)死点(dian)，将(jiang)上(shang)(shang)模(mo)块(kuai)(kuai)装入滑块(kuai)(kuai)模(mo)柄槽内，摆正放平；将(jiang)螺钉、顶丝旋紧，上(shang)(shang)模(mo)块(kuai)(kuai)与滑块(kuai)(kuai)底面不(bu)得有间隙(xi)；

将床面擦抹干(gan)净，去净油污铁(tie)屑后(hou)，将下(xia)模(mo)(mo)(mo)块(kuai)放(fang)(fang)在冲(chong)(chong)(chong)床台面上(shang)；点动开车或手盘大轮，使滑块(kuai)至下(xia)死(si)点纫入下(xia)模(mo)(mo)(mo)，调整连杆高(gao)度，使模(mo)(mo)(mo)具(ju)冲(chong)(chong)(chong)程合适；调整冲(chong)(chong)(chong)模(mo)(mo)(mo)间隙(xi)，保证周围间隙(xi)一致(zhi)；将下(xia)模(mo)(mo)(mo)块(kuai)压板(ban)(ban)压紧、压平(ping)，垫铁(tie)与底(di)模(mo)(mo)(mo)盘要(yao)等(deng)高(gao)度，固定点要(yao)对称；锁(suo)紧连杆，检(jian)查模(mo)(mo)(mo)具(ju)有无松动现(xian)象；进行试冲(chong)(chong)(chong)料，检(jian)查断(duan)面是否整齐(qi)、均匀(yun)、一致(zhi)；按尺寸要(yao)求调整制板(ban)(ban)，定好垂直基(ji)准（前后(hou)）和水平(ping)基(ji)准（左右）；了解到在加工(gong)(gong)中(zhong)料要(yao)与制板(ban)(ban)靠紧，在底(di)模(mo)(mo)(mo)上(shang)要(yao)放(fang)(fang)平(ping)； 冲(chong)(chong)(chong)孔、抹角时要(yao)注意加工(gong)(gong)方向，避免(mian)冲(chong)(chong)(chong)错；加工(gong)(gong)完(wan)的零(ling)件应分类放(fang)(fang)置整齐(qi)并(bing)加以标识。
