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(zhǎng)的缸筒需154小時(shí)，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(shí)，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(wú)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。

style="text-indent:25px">嚴(yán)格的純潔度要求。鋼的純潔度是指鋼中所含非金屬夾雜物的多少，純潔度越高，鋼中的非金屬夾雜物越少。軸承鋼中的氧化物、硅酸鹽等有害夾雜物是導(dǎo)致軸承早期疲勞剝落、顯著降低軸承壽命的主要原因。特別是脆性?shī)A雜物危害很大，由于在加工過程中容易從金屬基體上剝落下來(lái)，嚴(yán)重影響軸承零件精加工后的表面質(zhì)量。因此，為了提高軸承的使用壽命和可靠性，必須降低冷拔圓鋼中夾雜物的含量。表面缺點(diǎn)包括裂紋、夾渣、毛刺、結(jié)疤、氧化皮等，內(nèi)部缺點(diǎn)包括縮孔、氣泡、白點(diǎn)、嚴(yán)重的疏松和偏析等。這些缺點(diǎn)對(duì)于軸承的加工、軸承的性能和壽命有很大的影響，在軸承材料標(biāo)準(zhǔn)中明確規(guī)定不允許出現(xiàn)這些缺點(diǎn)。新鄉(xiāng)冷拔扁鋼銷售</p><p
