Two methods of inspecting copper tile

Release date:2019-09-19 08:35 source:Original click:

 冲床曲轴与铜瓦配合检查有两种方法:1、刮研法,用曲轴作为心棒与铜瓦相互研磨(用红丹粉作为显色剂),然后刮研铜瓦上面的接触点,一般接触点按要求为6-8点/25*25mm内为合格。2、尺寸检查,现在不少冲床铜瓦配合用精镗法取代了过去的人工刮研的方法,提高工效和降低工人劳动强度。这时,配合就要检查配合尺寸了。建议的配合间隙为1/1000左右,即直径是Φ1000的曲轴其与铜瓦的配合间隙为1mm。实际上我们不可能用到这么大直径的曲轴。用千分尺与内量表检具准确测量出其直径尺寸。两种配合方法都要注意铜瓦润滑油槽的修圆与修角。
