钢筋切断机的安全操作 | 2012-7-18 7:35:00
(1) 接送料的工作台面应和切刀下部保持水平,工作台的长度可根据加工材料长度确定。加工较长的钢筋时,应有专人帮扶,并听从操作人员指挥,不得任意推拉。
(2) 启动前,必须检查切刀应无裂纹,刀架螺栓紧固,防护罩牢靠。然后用手转动皮带轮,检查齿轮啮合间隙,调整切刀间隙。
(3) 启动后,应先空运转,检查各传动部分及轴承运转正常,方可操作。
(4) 机械未达到正常转速时不得切料。切断时必须使用切刀的中、下部位,握紧钢筋对准刀口迅速送入,操作者应站在固定刀片一侧用力压住钢筋,应防止钢筋末端弹出伤人。严禁用两手分在刀片两边握住钢筋俯身送料。
(5) 不得剪切直径及强度超过机械铭牌规定的钢筋和烧红的钢筋。一次切断多根钢筋时,其总截面积应在规定范围内。
(6) 剪切低合金钢时,应更换高硬度切刀,剪切直径应符合机械铭牌规定。
(7) 切断短料时,靠近刀片的手和刀片之间的距离应保持150mm以上,如手握端小于400mm时,应用套管或夹具将钢筋短头压住或夹牢。
(8) 运转中严禁用手直接消除附近的断头和杂物,钢筋摆动周围和刀口附近非操作人员不得停留。
(9) 当发现机械运转不正常、有异常响声或切刀歪斜时,应立即停机检修。维修保养必须停机,切断电源后方可进行。
(10) 液压传动式切断机作业前,应检查并确认液压油位及电动机旋转方向符合要求。启动后,应空载运转,松开放油阀,排净液压缸体内的空气,方可进行切筋。
(11) 手动液压式切断机使用前,应将放油阀按顺时针方向旋紧,切割完毕后,应立即按逆时针方向旋松。作业中,手应持稳切断机,并戴好绝缘手套。
(12) 作业后应切断电源,用钢刷消除切刀间的杂物,进行整机清洁润滑。
