Description

A preheated cable stripping knife

technical field

The utility model relates to an electric power tool, in particular to a preheating type cable stripping knife.

Background technique

During the construction, maintenance and intelligent upgrading of substations, it is necessary to rewire various old wires and cables, or directly relay new cables. Whether rewiring old cables or re-routing new cables, the cable ends need to be stripped to allow for distribution and connection of the cable cores.

When stripping the cable sheath, a stripping knife or stripper is required. The peeling tools currently used mainly include electrician's knife, hook knife and wallpaper knife. The shortcomings of the above three tools mainly contain the following points: 1. The use process is not safe. Due to the smooth appearance of the cable, it is easy to slip when peeling. Construction workers often cut their hands or cut their work clothes during the operation, and there are even bloody incidents of cutting other parts of the body. Especially in winter construction, the cable sheath will become harder, and it will be more difficult to peel it off with ordinary tools, and excessive force will seriously threaten the safety of operators, so it is very unsafe to use such tools in the process of peeling the cable sheath . 2. Low work efficiency. It takes about 1 minute to strip 1 meter of cable with traditional tools, and the stripping time will be longer in winter or when the cable is armored. For example, to build a new factory station, 500 cables need to be stripped, and the outer skin of each cable is stripped by 2 meters at each end, so a total of 33 man-hours are required. 3. It is easy to scratch the cable core. When peeling with the above tools, the extent to which the stripping knife penetrates the cable is difficult to control, and it is easy to cut the cable core.
