【技術實現步驟摘要】
本專利技術涉及一種建筑鋼筋的調直設備,特別是一種具有延伸功能的混合壓輪式鋼 筋調直機。
技術介紹
根據我國最新審定修改的《混凝土結構工程施工質量驗收規范》5、3、2A條的規 定,以盤卷形式供貨的鋼筋,調直后允許單位長度重量負偏差為<8-10%。即盤卷供貨的 HRB300以下強度級的鋼筋調直后允許單位長度重量負偏差為< 10% ;盤卷供貨的HRB335以 上強度級的鋼筋調直后允許單位長度重量負偏差為< 8%。該規定的制訂,是基于盤卷鋼筋 在調直加工時使之產生一定延伸的情況下,鋼筋的強度會稍有提高,而其它物理指標沒有 多大變化,而且在國家標準的范圍內。因此,盤卷鋼筋在調直加工時使之產生一定延伸,不 但可以提高建筑質量,還可大量節約建筑用鋼材。因盤卷要經鋼筋調直機調直加工后才能用于建筑混凝土內,而目前鋼筋調直機的 結構有兩種1、旋轉框架式鋼筋調直機。運行時,調直塊或調直輥繞著被牽引經過的鋼筋作螺旋運 動。如果將調直塊或調直輥在鋼筋上壓得過量,則調直出來的鋼筋會成麻花形的扭曲,這種 結構的調直機只能將鋼筋調直而無法使之延伸。2、壓輪式鋼筋調直機。其包括由相互錯開的兩排調直輪、兩排調直輪軸和調直輪 架組成的壓輪式調直機構,相互錯開的兩排調直輪通過調直輪軸安裝在調直輪架上,下面 一排調直輪通過牽調直軸與原動機的動力輸出組件相連,即下面一排調直輪全為主動輪, 上面一排調直輪全為被動輪,被加工的鋼筋在主動輪與被動輪中間,被動輪通過調整機構 將擱在主動輪上的鋼筋壓彎。主動輪、被動輪均是沿鋼筋軸向轉動,運行時鋼筋在主動輪的 驅動下不停地前進,而眾多的被動輪 ...
