康弘機(jī)械冷拔方式：生產(chǎn)高精度冷拔管──液壓缸體與傳統(tǒng)的切削工藝比較，具有以下特點(diǎn)：（1）生產(chǎn)效率高：用傳統(tǒng)的方法生產(chǎn)一根內(nèi)徑420毫米，12米長的缸筒需154小時，用冷拔方法生產(chǎn)只需4分鐘。（2）成品率高：由于鏜孔的滾壓頭兼起導(dǎo)向作用，在切削過程中，毛坯管由于自重產(chǎn)生撓度，致使?jié)L壓頭和鏜刀走偏，造成廢品。成品率只能達(dá)到60%左右，而用冷拔方法生產(chǎn)，成品率可達(dá)95%以上。（3）金屬利用率高：用傳統(tǒng)的鏜孔方法制造缸體，金屬利用率只有50-70%。用拉拔方法生產(chǎn)時，金屬不但不被切削成鐵末，反而可以得到30%的延伸，金屬利用率可達(dá)95%。（4）能改善成品管金屬的機(jī)械性能：用拉拔方法生產(chǎn)，使毛坯得到30%以上的塑性變形，由于加工硬化而使成品管金屬的強(qiáng)度限大為提高。一般在成品管內(nèi)層強(qiáng)度限提高達(dá)60%。高精度冷拔管是用無縫熱軋鋼管、直縫焊管為坯料，經(jīng)過化學(xué)處理后在**冷拔機(jī)上，通過特種變形原理設(shè)計(jì)的模具進(jìn)行拉拔，生產(chǎn)出高精度管。其尺寸精度達(dá)H10～H8，直線度達(dá)0.35～0.5mm/m，表面粗糙度達(dá)Ra1.6-0.4。
