冷拔六角鋼有彎曲的部分應該如何調整處理？冷拔六角鋼在某一彎曲段落內，有內外扭曲者時，應先調打內扭，后調打外扭。如果要熱調冷拔六角鋼的話，也應盡量使用平錘，以防產生錘痕。關于冷拔六角鋼機械調平法，一般是使用壓力機調正，頂壓扭曲時，須用胎型。冷拔六角鋼上一般的彎曲部分可以通過冷調的方式予以改善，這時候須將下部墊成空懸，也就是確保彎曲凸面向上，然后其凸面部分。若是六角鋼邊面向內扭曲時，可依照扁鋼調平法進行調平;冷拉六角鋼邊面上外扭曲時，可放入三角凹胎內調打之。

康弘機械冷拔方式：生產高精度冷拔管──液壓缸體與傳統(tǒng)的切削工藝比較，具有以下特點：（1）生產效率高：用傳統(tǒng)的方法生產一根內徑420毫米，12米長的缸筒需154小時，用冷拔方法生產只需4分鐘。（2）成品率高：由于鏜孔的滾壓頭兼起導向作用，在切削過程中，毛坯管由于自重產生撓度，致使?jié)L壓頭和鏜刀走偏，造成廢品。成品率只能達到60%左右，而用冷拔方法生產，成品率可達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95%。（4）能改善成品管金屬的機械性能：用拉拔方法生產，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度限大為提高。一般在成品管內層強度限提高達60%。高精度冷拔管是用無縫熱軋鋼管、直縫焊管為坯料，經過化學處理后在**冷拔機上，通過特種變形原理設計的模具進行拉拔，生產出高精度管。其尺寸精度達H10～H8，直線度達0.35～0.5mm/m，表面粗糙度達Ra1.6-0.4。
