技术介绍
在电线电缆领域,额定电压0.6/1kV电力电缆导体截面在50mm2以上且芯数在2芯以上的电缆,导体均采用异型紧压导体,主要分为180°两芯电缆、120°三芯电缆、90°四芯电缆及3+1芯、3+2芯和4+1芯,在导体绞合工序,我们将导体紧压为60°、72°、75°、80°、90°等扇形形状,并将异型导体挤包绝缘层后再成缆为圆形缆芯,这样既可减少电缆外径,又使得电缆的结构更加稳定。而在异型导体绞合工序,目前多数电缆企业普遍采用的导体压轮模具(如图1、2),分为上轮1和下轮2,上轮和下压轮中间各自装有圆形滚动轴承3,操作人员通过将上下压轮固定于压模座中,使用丝杆调节上下压轮的模间距,上下压轮形成的异型轮廓面4(图3、4)将导体紧压成异型。但随着导体压轮的长期使用,出现的问题也随之而来,因压轮模具上轮为V形面5、下轮为R弧面6,上下轮紧压接触时受力仅为两点受力,长期受力紧压导致下轮出现卷边、毛刺,上轮出现压痕、磨损现象,且上下轮接触紧压时无定位保障,当磨损严 ...
