冷拔六角鋼有彎曲的部分應(yīng)該如何調(diào)整處理？冷拔六角鋼在某一彎曲段落內(nèi)，有內(nèi)外扭曲者時(shí)，應(yīng)先調(diào)打內(nèi)扭，后調(diào)打外扭。如果要熱調(diào)冷拔六角鋼的話，也應(yīng)盡量使用平錘，以防產(chǎn)生錘痕。關(guān)于冷拔六角鋼機(jī)械調(diào)平法，一般是使用壓力機(jī)調(diào)正，頂壓扭曲時(shí)，須用胎型。冷拔六角鋼上一般的彎曲部分可以通過冷調(diào)的方式予以改善，這時(shí)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(nèi)扭曲時(shí)，可依照扁鋼調(diào)平法進(jìn)行調(diào)平;冷拉六角鋼邊面上外扭曲時(shí)，可放入三角凹胎內(nèi)調(diào)打之。
