截齒的焊接設備使用你會了嗎
  截齒,分為采煤機截齒和掘進機截齒,是開采掘進機器上的零件多用在采礦和隧道等建設等方面,其中掘進機截齒在硬度上要求較高。
  1、準備工作:按照訂單領取額定數量的鍛件、合金頭、銅焊片、卡簧、包裝桶。開機檢查水泵、冷卻塔、輸送帶等設備是否運轉正常,檢測淬火液濃度是否適中,查看水箱冷卻水是否足夠,提前對回火爐進行升溫,按照硬度要求設定溫度,做好生產準備。
  2、鍛件加熱:按下IGBT“主電開”按鈕啟動主電,將控制開關旋至“遠程”檔位,在遠程操作箱開啟“逆變”開關,緩慢調節“功率調節”開關至規定功率開始生產,截齒走到感應圈出口處時,探測溫度是否在920-950℃之間,如有誤差及時調功率。
  3、擠壓焊頭:銅焊片溶化后,擠壓合金頭使已融化的焊液均勻環繞合金頭,使產品達到應有的技術要求。
  4、截齒淬火:已焊接好的的鍛件在進入適當濃度的淬火池的工程中,嚴格控制淬火液的溫度(低于45℃)。
  5、工件回火:按照設定的溫度對截齒回火,及時調換盛放工件的框子,室溫下冷卻回火后的截齒。
