冲压安全通则 | 2012-2-10 7:45:00
1.加强冲压机械的定期检修,严禁带病运转。开始操作前,必须认真检查防护装置是否完好,离合器制动装置是否灵活和安全可靠;应把工作台上的一切不必要的物件清理干净,以防工作时震落到脚踏开关上,造成冲床突然启动而发生事故。
2.冲小工件时,不得用手,应该用专用工具,最好安装自动送料装置。
3.操作者对脚踏开关的控制必须小心谨慎,装卸工件时,脚应离开脚踏开关。严禁其他人员在脚踏开关的周围停留。
4.如果工件卡在模子里,应用专用工具取出,不准用手拿,并应先将脚从脚踏板上移开。
5.注意模具的安装、调整与拆卸中的安全。
①安装前应仔细检查模具是否完整,必要的防护装置及其他附件是否齐全。
②检查压力机和模具的闭合高度,保证所用模具的闭合高度介于压力机的最大与最小闭合高度之间。
③使用压力机的卸料装置时,应将其暂时调到最高位置,以免调整压力机闭合高度时被折弯。
④安装、调整模具时,对小型压力机(公称压力150吨以下)要求用手扳动飞轮,带动滑块作上下运动进行操作;而对大型压力机用动力操纵,采用按微动按钮寸动,不许使用脚踏开关操纵。
⑤模具的安装一般先装上模,后装下模。
⑥模具安装完后,应进行空转或试冲,检验上、下模位置的正确性以及卸料、打料及顶料装置是否灵活、可靠,并装上全部安全防护装置,直至全部符合要求方可投人生产。
⑦拆卸模具时,应切断电源,用手或撬杆转动压力机飞轮(大型压力机则按微动按钮开启电动机),使滑块降至下死点,上、下模处于闭合状态。而后,先拆上模,拆完后将滑块升至上死点,使其与上模完全脱开,最后拆去下模,并将拆下的模具运到指定地点,再仔细擦去表面油污,涂上防锈油,稳妥存放,以备再用。
