【摘要】在我國(guó),冷擠壓技術(shù)已得到越來(lái)越多的應(yīng)用,有較多種類的有色金屬與黑色金屬可用冷擠壓方法進(jìn)行生產(chǎn),冷擠壓零件的復(fù)雜程度亦不斷提高。本文討論了冷擠壓的許用變形程度、潤(rùn)滑的選用,冷模鍛的應(yīng)用與不銹綱的擠壓各個(gè)問(wèn)題。由于模具結(jié)構(gòu)的合理化以及模具材料的發(fā)展,冷擠壓模具壽命得到不斷的提高。冷擠壓是機(jī)械制造中的一種金屬壓力加工少、無(wú)切削新工藝。用冷擠壓方法進(jìn)行生產(chǎn)可以大幅度地提高勞動(dòng)生產(chǎn)率、節(jié)約原材料、可以保證產(chǎn)品質(zhì)量,生產(chǎn)成木亦得到顯著的下降。近年以來(lái),各工業(yè)先進(jìn)國(guó)家對(duì)冷擠壓的發(fā)展極為重視,這門新技術(shù)已得到廣泛的應(yīng)用。 在我國(guó),解放前的冷擠壓技術(shù)極為落后;解放后,這門新工藝得到了發(fā)展。近年以來(lái),冷擠壓在各部門得到了越來(lái)越多的應(yīng)用。以下就冷擠壓材料、變形工序以及冷擠壓模具各個(gè)方面進(jìn)行討論。冷擠壓用材料在我國(guó),純鋁、防誘鋁、鍛鋁、硬鋁、紫銅、無(wú)氧銅、含銅量在62%以上的黃銅都已在五十年代應(yīng)用。

Impact extrusion technology in our country's application and progress

 [Abstract] In our country, the impact extrusion technology obtained more and more applications, has the many type non-ferrous metals and the ferrous metal available impact extrusion method carries on the production, the impact extrusion components complex degree also unceasingly enhances. This article discussed impact extrusion Xu Yong the distortion degree, lubrication selection, cold drop forging application and stainless outline extrusion each question. As a result of the mold structure's rationalization as well as the mold material's development, the swaging die set life has the unceasing enhancement. The impact extrusion is in machine manufacture's one metal shaping few, does not have cuts the new craft. Carries on the production with the impact extrusion method to be possible to raise the labor productivity, the frugal raw material, to be possible large scale the quality assurance, produces Cheng Muyi to obtain the remarkable drop. Since recent years, the various industries advanced countries extremely have taken seriously to the impact extrusion development, this new technology obtained the widespread application. In our country, the pre-liberation impact extrusion technology falls behind extremely; After the liberation, this new craft obtained the development. Since recent years, the impact extrusion obtained more and more applications in various departments. The following on the impact extrusion material, the distortion working procedure as well as swaging die set each aspect carries on the discussion. First, the impact extrusion with the material in our country, the pure aluminum, against tempts the aluminum, to hammer the aluminum, the duralumin, the red copper, the oxygen-free copper, the copper content in 62% above brasses in the 50s should。
