五金沖壓件的硬度檢測

 五金沖壓件的(de)(de)硬度(du)檢測采(cai)用(yong)洛(luo)氏硬度(du)計(ji)。小型的(de)(de)、具(ju)有復雜形狀的(de)(de)沖壓(ya)(ya)件，可以用(yong)來測試(shi)平面(mian)很小，無法(fa)在普通臺式洛(luo)氏硬度(du)計(ji)上檢測。PHP系列便攜式表(biao)面(mian)洛(luo)氏硬度(du)計(ji)適用(yong)于測試(shi)這些沖壓(ya)(ya)件的(de)(de)硬度(du)。合金沖壓(ya)(ya)件是(shi)金屬加工(gong)、機械制造   常用(yong)的(de)(de)零件。沖壓(ya)(ya)件加工(gong)是(shi)利用(yong)模具(ju)使(shi)金屬板帶發生分(fen)離或成形的(de)(de)加工(gong)方法(fa)。其應用(yong)范(fan)圍廣(guang)闊。
　　沖壓(ya)件加工(gong)包(bao)括沖裁、彎曲、拉深(shen)、成形、精整等工(gong)序。沖壓(ya)件加工(gong)的(de)材(cai)(cai)料主要是熱軋或冷軋（以(yi)冷軋為(wei)主）的(de)金(jin)屬板帶材(cai)(cai)料，例如碳鋼板、合(he)金(jin)鋼板、彈簧鋼板、鍍(du)鋅板、鍍(du)錫板、不銹(xiu)鋼板、銅(tong)及(ji)銅(tong)合(he)金(jin)板、鋁及(ji)鋁合(he)金(jin)板等。
　　沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)件(jian)所(suo)使用的(de)(de)模(mo)具稱為沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)模(mo)具，簡稱沖(chong)(chong)(chong)模(mo)。沖(chong)(chong)(chong)模(mo)是將材料（金屬或非(fei)金屬）批(pi)量(liang)加(jia)工(gong)(gong)成所(suo)需沖(chong)(chong)(chong)件(jian)的(de)(de)工(gong)(gong)具。沖(chong)(chong)(chong)模(mo)在沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)中(zhong)至關重(zhong)要，沒有符合(he)(he)要求的(de)(de)沖(chong)(chong)(chong)模(mo)，批(pi)量(liang)沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)生產(chan)就難以(yi)進行；沒有的(de)(de)沖(chong)(chong)(chong)模(mo)，的(de)(de)沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)工(gong)(gong)藝就無(wu)法實現。沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)工(gong)(gong)藝與(yu)模(mo)具、沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)設(she)備和(he)沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)材料構成沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)加(jia)工(gong)(gong)的(de)(de)三要素(su)，只有它們相(xiang)互(hu)結合(he)(he)才能得出沖(chong)(chong)(chong)壓(ya)(ya)(ya)(ya)件(jian)。
　　與機械加(jia)工及(ji)塑性加(jia)工的其它方法相比，沖(chong)壓加(jia)工無論在技術方面還(huan)是經濟(ji)方面都具(ju)有許(xu)多   的優點。
　　沖(chong)(chong)壓加(jia)工(gong)是借助于(yu)常規(gui)或沖(chong)(chong)壓設備(bei)的動(dong)力(li)(li)，使板(ban)(ban)料(liao)在模(mo)具里直接受到(dao)變形(xing)力(li)(li)并進(jin)行變形(xing)，從而獲得   形(xing)狀,尺寸和性能的產品零件(jian)的生產技術。板(ban)(ban)料(liao)，模(mo)具和設備(bei)是沖(chong)(chong)壓加(jia)工(gong)的三要素。沖(chong)(chong)壓加(jia)工(gong)是一種金屬冷(leng)變形(xing)加(jia)工(gong)方法。所以，被(bei)稱之(zhi)為(wei)冷(leng)沖(chong)(chong)壓或板(ban)(ban)料(liao)沖(chong)(chong)壓，簡稱沖(chong)(chong)壓。它是金屬塑性加(jia)工(gong)（或壓力(li)(li)加(jia)工(gong)）的主要方法之(zhi)一，也隸屬于(yu)材料(liao)成(cheng)型工(gong)程技術。
　　由(you)于五金沖壓件沖(chong)壓(ya)(ya)具有(you)如(ru)(ru)此優(you)越性(xing)，沖(chong)壓(ya)(ya)加(jia)工(gong)在國民(min)經濟各(ge)個(ge)應(ying)用(yong)范圍相當廣(guang)泛(fan)。例(li)如(ru)(ru)，在宇航，航空，，機(ji)械，農(nong)機(ji)，電(dian)子，信息，鐵道，郵電(dian)，交(jiao)通(tong)，化工(gong)，器(qi)具，日用(yong)電(dian)器(qi)及輕工(gong)等部門里(li)都(dou)(dou)有(you)沖(chong)壓(ya)(ya)加(jia)工(gong)。不(bu)但整(zheng)個(ge)產(chan)業界都(dou)(dou)用(yong)到它(ta)，而(er)且每(mei)個(ge)人都(dou)(dou)直接與(yu)沖(chong)壓(ya)(ya)產(chan)品發生聯系。像飛(fei)機(ji)，火車(che)(che)，汽車(che)(che)，拖拉(la)機(ji)上就有(you)許多(duo)大，中，小型沖(chong)壓(ya)(ya)件(jian)(jian)。小轎(jiao)車(che)(che)的車(che)(che)身，車(che)(che)架(jia)及車(che)(che)圈等零部件(jian)(jian)都(dou)(dou)是(shi)(shi)沖(chong)壓(ya)(ya)加(jia)工(gong)出來的。據有(you)關調查統(tong)計，自行車(che)(che)，縫(feng)紉(ren)機(ji)，手表(biao)里(li)有(you)80%是(shi)(shi)沖(chong)壓(ya)(ya)件(jian)(jian)；電(dian)視(shi)機(ji)，收錄機(ji)，攝(she)像機(ji)里(li)有(you)90%是(shi)(shi)沖(chong)壓(ya)(ya)件(jian)(jian)；還(huan)有(you)食品金屬罐殼，鋼精鍋爐，搪(tang)瓷(ci)盆(pen)碗及不(bu)銹鋼餐具，全都(dou)(dou)是(shi)(shi)使用(yong)模具的沖(chong)壓(ya)(ya)加(jia)工(gong)產(chan)品；就連(lian)電(dian)腦(nao)的硬件(jian)(jian)中也缺少不(bu)了(le)沖(chong)壓(ya)(ya)件(jian)(jian)。
