探析大連沖壓模具的加工特點

  國內的模具產業在世界模具行業當中處于低端，出現這樣的形勢與整個行業科技水平低，價格戰持續有關。模具行業想要有所發展，必須不斷增加研發資金，加大科技含量，生產出具有核心競爭力的產品。加大產品研發力度，才能夠真正改變目前的競爭模式。為什么國內的模具產業一直打價格戰?國內目前從事模具生產的企業比較多，但是規模比較小，基本都是小作坊模式，科技含量很低。小型的沖壓模具企業(ye)生產的(de)(de)(de)產品基(ji)本(ben)都是(shi)模仿，導致中低端的(de)(de)(de)同質化模具越來(lai)越多。熱沖壓成(cheng)(cheng)形(xing)(xing)中所使(shi)用(yong)的(de)(de)(de)鋼(gang)板(ban)(ban)是(shi)一種特殊的(de)(de)(de)硼合(he)金鋼(gang)板(ban)(ban)，這種鋼(gang)板(ban)(ban)不同于(yu)傳統(tong)的(de)(de)(de)冷成(cheng)(cheng)形(xing)(xing)超高(gao)強(qiang)(qiang)鋼(gang)。現在應(ying)用(yong)比(bi)較廣(guang)泛的(de)(de)(de)雙(shuang)相鋼(gang)、復相鋼(gang)等冷成(cheng)(cheng)形(xing)(xing)高(gao)強(qiang)(qiang)度鋼(gang)板(ban)(ban)一般是(shi)在常溫下通(tong)過冷沖壓的(de)(de)(de)方(fang)法成(cheng)(cheng)形(xing)(xing)，成(cheng)(cheng)形(xing)(xing)前后零件的(de)(de)(de)顯微組織(zhi)和機械強(qiang)(qiang)度基(ji)本(ben)不發生改變。

  沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)行業是一(yi)個涉及領(ling)域極其廣泛的(de)(de)(de)行業，深入到制造業的(de)(de)(de)方方面面，在國外(wai)將沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)稱(cheng)(cheng)為(wei)板材成(cheng)(cheng)(cheng)(cheng)形(xing)(xing)。在我國也(ye)有這樣稱(cheng)(cheng)呼的(de)(de)(de)。中國的(de)(de)(de)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)有時(shi)(shi)也(ye)稱(cheng)(cheng)板材成(cheng)(cheng)(cheng)(cheng)形(xing)(xing), 但略有區別。所謂板材成(cheng)(cheng)(cheng)(cheng)型是指(zhi)用板材、薄(bo)(bo)壁管、薄(bo)(bo)型材等作為(wei)原材料(liao)(liao)(liao)進(jin)行　塑性加(jia)工(gong)的(de)(de)(de)成(cheng)(cheng)(cheng)(cheng)形(xing)(xing)方法(fa)統(tong)稱(cheng)(cheng)為(wei)板材成(cheng)(cheng)(cheng)(cheng)形(xing)(xing)，此(ci)時(shi)(shi)，厚板方向的(de)(de)(de)變形(xing)(xing)一(yi)般不著重考慮(lv)。 沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)成(cheng)(cheng)(cheng)(cheng)形(xing)(xing)是金屬壓(ya)(ya)(ya)(ya)(ya)力(li)加(jia)工(gong)方法(fa)之一(yi)，它是建(jian)立在金屬塑性變形(xing)(xing)理(li)論基礎上的(de)(de)(de)材料(liao)(liao)(liao)成(cheng)(cheng)(cheng)(cheng)形(xing)(xing)工(gong)程技術(shu)，沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)加(jia)工(gong)的(de)(de)(de)原材料(liao)(liao)(liao)一(yi)般為(wei)板料(liao)(liao)(liao)或帶料(liao)(liao)(liao)，故也(ye)稱(cheng)(cheng)板料(liao)(liao)(liao)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)。沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)工(gong)藝是指(zhi)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)加(jia)工(gong)的(de)(de)(de)具(ju)體方法(fa)（各種沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)工(gong)序的(de)(de)(de)總和）和技術(shu)經驗；沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)模具(ju)是指(zhi)將板料(liao)(liao)(liao)加(jia)工(gong)成(cheng)(cheng)(cheng)(cheng)沖(chong)(chong)壓(ya)(ya)(ya)(ya)(ya)零(ling)件(jian)的(de)(de)(de)特(te)殊(shu)專用工(gong)具(ju)。
