冲(chong)(chong)(chong)(chong)压(ya)(ya)是(shi)靠压(ya)(ya)力机(ji)和(he)(he)模(mo)具对板(ban)材、带材、管材和(he)(he)型材等施加外力，使之产生塑(su)性(xing)(xing)变形或分离，从而获得所需形状和(he)(he)尺寸的(de)(de)(de)工(gong)(gong)件(jian)（冲(chong)(chong)(chong)(chong)压(ya)(ya)件(jian)）的(de)(de)(de)成(cheng)形加工(gong)(gong)方法。冲(chong)(chong)(chong)(chong)压(ya)(ya)和(he)(he)锻(duan)造同(tong)属塑(su)性(xing)(xing)加工(gong)(gong)（或称(cheng)压(ya)(ya)力加工(gong)(gong)），合称(cheng)锻(duan)压(ya)(ya)。冲(chong)(chong)(chong)(chong)压(ya)(ya)的(de)(de)(de)坯(pi)料主(zhu)要(yao)是(shi)热轧和(he)(he)冷轧的(de)(de)(de)钢(gang)板(ban)和(he)(he)钢(gang)带。全(quan)世(shi)界(jie)的(de)(de)(de)钢(gang)材中，有60～70%是(shi)板(ban)材，其中大部分经(jing)过(guo)冲(chong)(chong)(chong)(chong)压(ya)(ya)制(zhi)(zhi)成(cheng)成(cheng)品(pin)。汽(qi)车(che)的(de)(de)(de)车(che)身、底盘(pan)、油箱、散(san)热器(qi)片，锅炉(lu)的(de)(de)(de)汽(qi)包，容(rong)器(qi)的(de)(de)(de)壳体，电(dian)(dian)机(ji)、电(dian)(dian)器(qi)的(de)(de)(de)铁(tie)芯硅钢(gang)片等都是(shi)冲(chong)(chong)(chong)(chong)压(ya)(ya)加工(gong)(gong)的(de)(de)(de)。仪(yi)器(qi)仪(yi)表、家用电(dian)(dian)器(qi)、自行车(che)、办公(gong)机(ji)械、生活器(qi)皿等产品(pin)中，也有大量冲(chong)(chong)(chong)(chong)压(ya)(ya)件(jian)。益阳金属冲(chong)(chong)(chong)(chong)压(ya)(ya)联系方式平板(ban)变压(ya)(ya)器(qi)铜(tong)片冲(chong)(chong)(chong)(chong)压(ya)(ya)的(de)(de)(de)过(guo)程包括铜(tong)片的(de)(de)(de)预处理、模(mo)具的(de)(de)(de)设计和(he)(he)制(zhi)(zhi)造、冲(chong)(chong)(chong)(chong)压(ya)(ya)机(ji)的(de)(de)(de)选择和(he)(he)操(cao)作、以及成(cheng)品(pin)的(de)(de)(de)检(jian)测等。

仪(yi)(yi)器仪(yi)(yi)表、家用(yong)电器、自(zi)行(xing)车、办(ban)公机械、生(sheng)活器皿等(deng)产(chan)品(pin)中，也有(you)大量(liang)冲(chong)(chong)(chong)压(ya)件。冲(chong)(chong)(chong)压(ya)加(jia)工是借助(zhu)于常(chang)规或**冲(chong)(chong)(chong)压(ya)设备(bei)的(de)(de)动力，使板(ban)料在模具里(li)直接受到(dao)变形(xing)力并进(jin)行(xing)变形(xing)，从而获(huo)得一(yi)定形(xing)状、尺寸(cun)和(he)性(xing)能的(de)(de)产(chan)品(pin)零件的(de)(de)生(sheng)产(chan)技(ji)术。板(ban)料，模具和(he)设备(bei)是冲(chong)(chong)(chong)压(ya)加(jia)工的(de)(de)三要素。按(an)冲(chong)(chong)(chong)压(ya)加(jia)工温(wen)度(du)分为热冲(chong)(chong)(chong)压(ya)和(he)冷冲(chong)(chong)(chong)压(ya)。前者适(shi)合(he)变形(xing)抗力高，塑性(xing)较差(cha)的(de)(de)板(ban)料加(jia)工；后者则在室温(wen)下进(jin)行(xing)，是薄板(ban)常(chang)用(yong)的(de)(de)冲(chong)(chong)(chong)压(ya)方(fang)法。它是金属(shu)塑性(xing)加(jia)工（或压(ya)力加(jia)工）的(de)(de)主要方(fang)法之一(yi)，也隶属(shu)于材料成型工程技(ji)术。

在每分钟(zhong)生(sheng)产数(shu)十(shi)、数(shu)百件冲压件的(de)情况下，在短(duan)暂(zan)时间内完成(cheng)送(song)料(liao)、冲压、出(chu)(chu)件、排废料(liao)等(deng)工(gong)序，常常发(fa)生(sheng)人身、设备和(he)(he)质(zhi)量(liang)事故。因此，冲压中的(de)安全(quan)生(sheng)产是一个非常重要(yao)的(de)问题。冲压的(de)安全(quan)措(cuo)施是：①实现(xian)机(ji)械化(hua)、自动(dong)化(hua)进出(chu)(chu)料(liao)。②设置(zhi)机(ji)械防(fang)护(hu)装(zhuang)置(zhi)，防(fang)止伤手(shou)(shou)。应用模具防(fang)护(hu)罩、自动(dong)退(tui)料(liao)装(zhuang)置(zhi)和(he)(he)手(shou)(shou)工(gong)工(gong)具进出(chu)(chu)料(liao)。③设置(zhi)电(dian)气(qi)(qi)保护(hu)、断电(dian)装(zhuang)置(zhi)。设置(zhi)光电(dian)或(huo)气(qi)(qi)幕(mu)保护(hu)开(kai)关、双手(shou)(shou)或(huo)多手(shou)(shou)串(chuan)联启动(dong)开(kai)关、防(fang)误操作装(zhuang)置(zhi)等(deng)。④改(gai)进离(li)合(he)器和(he)(he)制动(dong)结构(gou)，在危险信号发(fa)出(chu)(chu)后，压力机(ji)的(de)曲(qu)轴、连杆、冲头能立即停止在原位上。铁(tie)冲压件的(de)生(sheng)产成(cheng)本相对(dui)较低，但是可以(yi)提高产品的(de)质(zhi)量(liang)和(he)(he)生(sheng)产效率，因此被应用于各(ge)种行业。
