安装冲模时应注意哪些问题？

[ 2011-7-27 15:54:00 | By: 杨远锋 ]

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。
