装冲模时应注意哪些问题? | 2012-3-6 16:43:00

装冲模时应注意哪些问题?

    在压力机上安装冲模是一件很重要的工作,冲模安装调整不好,轻则造成冲压件报废,重则将威胁人身和设备的安全。因此在安装冲模前,必须要熟悉生产工艺,全面了解该工序所用冲模的结构特点及其使用条件,熟悉制件结构性能、作用和技术条件,冲压材料和工艺性能及该工序的工艺要求;要检查压力机的刹车、离合器及操纵机构是否正常,只有在确认压力机的技术状态良好,各项安全措施齐全、完备,才能按照冲模安装操作规程进行冲模的安装工作。
    在安装冲模时要先检查压力机的打料装置,应将其暂时调整到最高位置,以免调整压力机闭合高度时折弯;要检查下模顶杆和上模打棒是否符合压力机打料装置的要求(大型压力机则检查气垫装置);要检查压力机和冲模的闭合高度,压力机的闭合高度应略大于冲模的闭合高度,防上发生事故;安装前,还应将上下模板及滑块底面的油污擦拭干净,并检查有无遗物、防上影响正确安装和发生意外事故。安装时.应断开或切断动力和锁住开关,安装次序是先上模后下模,将上下模安好后.应用手板动飞轮,使滑块走完半个行程,检查上下模对正位置是否正确,经检查安装无误后,可升空车试冲几次.直至符合要求,将螺杆锁紧并调整好打料位置,重新安上全部安全装置,并检查、调整和运行。
