Description

Power cable outer semiconductive layer stripping tool

Technical field:

The utility model relates to a manufacturing tool for a machine-related power cable end, in particular to a stripping tool for a semiconductive layer at the end of a cable.

Background technique:

With the popularization and application of cross-linked polyethylene power cables, in the actual operation of cables in the field, the operation link that is not easy to be controlled by humans gradually appears. The difficulty that is generally recognized is: the outer semi-conductive layer of the cross-linked cable core With the stripping and cutting of the insulation! This is also the core of quality control in the installation and maintenance of power cables. According to the requirements of the operating process standard, the dimensional accuracy of the stripping and cutting is very high. At the same time, due to the complicated installation and maintenance process of the cross-linked cable, it is our goal to grasp the standardized installation and maintenance process. Facts have also proved that one-third of the accidents caused by power cable accidents are hidden dangers caused by the failure of installation and maintenance quality to meet the process standards. Over the years, in addition to continuous training and improving the operation skills of maintenance and installation personnel, we have also spent a lot of money on special tools for power cable installation, and purchased some special cable stripping and cutting tools imported from the United States and Italy. However, some of these imported special tools are not acclimatized and do not conform to my country's national conditions. Some of them have complex structures and high costs, and there are still three major problems: 1. A correspondingly large operating space is required; 2. The peeling and cutting are not clean; 3. Work efficiency Low and slow. "Popular Electricity" published in January 2007 discloses a "peeling and cutting process for the outer semiconductive layer of the heat-shrinkable terminal head of cross-linked cables". Stripping the incision, and finally peeling and cutting with wire cutters, the process is complicated, and it requires the cooperation of many people, and the work efficiency is low.

Utility model content:

The technical problem to be solved by the utility model is to provide a stripping and cutting tool for the outer semiconductive layer of the power cable in view of the above deficiencies. All in one go, not only conforms to the on-site standardized operation, but also is a single fool's operation, which is convenient, quick and versatile.

The technical scheme that the utility model takes is:

A tool for peeling and cutting the outer semiconductive layer of a power cable, mainly composed of a ring frame and glands arranged on both sides of the ring frame, a knife holder is connected to the ring frame, and a knife head is provided in the knife holder, and the knife head includes a ring cutting tool The cutter head and three cross-cutting cutter heads are arranged evenly at intervals of 120° along the circumferential direction of the ring frame. The cutter head is perpendicular to the section of the ring frame, and the tail end of the knife frame has an adjustment piece.

The cutter head is a thin slice cutter head in the shape of a grinding wheel.

Positioning guide wheels are arranged on both sides of the transverse cutter head opposite to the circular cutter head.

Two clamping blocks are arranged in the tool holder, and the cutter head is connected between the two clamping blocks in the tool holder, and the diameter of the cutter head is 10-20 mm larger than the radial length of the clamping block.

Both the ring frame and the gland have pin holes, and the gland is fixedly connected to both sides of the ring frame by fixing pins.

The tool rest is magnetically connected to the adjustment piece, and the adjustment piece is threadedly connected to the ring frame.

The beneficial effect that the utility model can reach is:

1. The utility model is a three-point cross-cutting cutter head and an independent ring-cutting cutter head evenly arranged on the ring frame. By positioning the guide wheel to limit the knife marks, the ring cutting and longitudinal cutting are controlled by a single person, and the sequential cutting is done in one go. , easy to use, high precision and fast speed.

2. The size of the utility model can be multiplied into various specifications according to the actual situation of the cable. It has low requirements on space conditions and personnel quality, strong versatility, and wide application range.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1 and Figure 2: the tool for stripping and cutting the outer semiconductive layer of the power cable is mainly composed of a ring frame 1 and glands 10 arranged on both sides of the ring frame 1. The ring frame 1 is connected with a knife holder 3 and a knife holder 3 A grinding wheel-shaped sheet cutter head 4 is provided inside, and the cutter head 4 is composed of a circular cutting cutter head 41 and three cross-cutting cutter heads 42 evenly arranged at 120° intervals along the circumferential direction of the ring frame. The center of the cross-cutting cutter head 42 is arranged on the same straight line, the ring-cutting cutter head 41 is parallel to the cross-section of the ring frame 1, the cross-cutting cutter head 42 is perpendicular to the cross-section of the ring frame 1, and the tail end of the knife rest 3 has an adjustment member 7, which is aligned with the ring cutter Positioning guide wheels 5 are arranged on both sides of the cross-cutting cutter head 42 opposite to the head 41 . Two clamping blocks 6 are arranged in the tool holder 3, and the cutter head 4 is connected between the two clamping blocks 6 in the tool holder 3, and the diameter of the cutter head 4 is greater than the radial length of the clamping block 6 by 10-20 mm. rice. Both the ring frame 1 and the gland 10 have pin holes 2 , and the gland 10 is affixed to both sides of the ring frame 1 through fixing pins 8 . The tool rest 3 is magnetically attached to the adjustment piece 7, and the adjustment piece 7 is screwed to the ring frame 1.

When in use, insert the cable 9 at the center of the ring frame 1, first make the ring cutter head 41 contact with the cable 9 and press it tightly, withdraw from the ring cutter head 41 after one rotation, and then make the three cross-cutting knives The head 42 is in contact with the cable 9 and compressed, pulled out straight to the outside, and finally the outer semiconductive layer that has been divided into three pieces is peeled off and polished with wire cutters.
