Abstract

The utility model belongs to an electrical engineering hand device. Cable is often adopted in power transmission, communicating and mechanical engineering. However, the operation of skinning the electric cable is difficult. A skinning knife for electric cable is designed to solve the problems of taking time and labour with an electrician knife to skin cables. The utility model comprises a transversal cutting cable knife and a longitudinal dissection cable knife. Both of the two knives adopt a centering device of a V-shaped groove, a screw thread or a bar to boost. Operators' hands are far away from knife tips. Compared with skinning cables with the electrician knife, the utility model has the advantages of simple operation, saving labour and time, high efficiency and safety.

Description

Skinning knife for electric cable

The utility model belongs to the manual tool of electrician's class.

As everyone knows, in transmission of electricity, communication, mechanical engineering, often adopt cable, sub-thread arranged, multiply is also arranged, around each strand electric wire and the outer surface of cable coating layer is all arranged, that this coating layer has is metal, rubber, plastics, line etc. various ways.Cut down length during use on demand earlier, peel off appearance again with each strand on coating layer.The general special-purpose cutter that all uses electrician's knife or grind temporarily.The operating cost strength of stripping cable skin, time-consuming and dangerous.Learn according to investigations and still do not have at present a kind of special dedicated tool.

The design's purpose is, effort time-consuming with electrician's knife stripping cable skin for solving and unsafe problem, the cable peeling cutter of a kind of special use of ad hoc meter, it can be applicable to the cable that thickness is different, can peel off different types of coating layer, rapid operation, saves time and safety.

Reach two knives vertically cutting the cable skin open by the cable peeling cutter that above design provided by transversely cutting cable skin and form a cover.

Its transversely cutting cable dermatotome is made up of knife rest, garden dish cutting knife, slide block and leading screw.Garden dish cutting knife is contained on the axle of knife rest front end, can rotate, cooperate with guide rail form between slide block and the knife rest, can move forward and backward, slide block links mutually with the interior bulb that compresses leading screw that cooperates of knife rest screwed hole, and the centre-height of V-type groove is consistent with the centre-height of cutterhead on the slide block.

It vertically cuts the cable dermatotome open is by upper and lower handle, and the fixed wheel of cutting knife and band V-type groove is formed.Last lower handle connects with a hinge axis, and the fixed wheel of band V-type groove is contained on the axle of lower handle, can rotate, and cutting knife is contained on the upper handle, and the point of a knife of cutting knife should align with the center line of fixed wheel.

Elder generation, between slide block and cutting knife, compresses cable clip by the length that need stay enough cable the end of a thread is installed with transversely cutting cable dermatotome during use with leading screw, garden Zhou Fangxiang by cable rotates this transversely cutting cable dermatotome, hold out against leading screw while changeing, cutting knife is cut gradually, till cutting.Attention: undue feed will diminish lead.Re-use and vertically cut the cable dermatotome open, open upper and lower handle, between fixed wheel and cutting knife, lower handle is gone up in the clamping of exerting oneself makes cutting knife penetrate coating layer with cable clip, and another hand is firmly pulled out cable fast, so just can cut the cable skin open.Horizontal, rip cutting is disconnected, and to remove the cable skin again after cutting open just easier.Two knives have all adopted the guide device of V-type groove, because the V-type groove has the function of automatic centering, make the size range of these two cutter work accommodations widen, and can shell the cable skin of diameter phi 10～φ 100mm.

Use the design's cable peeling cutter to show following advantage with generally comparing with the operation of electrician's knife stripping cable skin: 1. to save the strength: laterally cutter is with the afterburning propelling of leading screw cutting depth, longitudinal knife lever reinforcing, and this all is the labour-saving device.The correcting of working angles is carried out automatically.And with electrician's knife in clamping, align, cut and all use manpower.2. wide accommodation, diameter dimension can both use from φ 10 to φ 100, because to direct problem effortlessly, as long as blade is sharp, various line skin all can cut.3. good operation and efficient height: compare with the electrician's knife peeling by experiment, efficient can improve 10 times, shells large diameter cable skin, and this cover specific purpose tool just can be brought into play its superiority more.4. safety: during with the design's cutter operation, hand is away from cutter, so safe.And during with the electrician's knife peeling, the hand of helping cable is always over against point of a knife, and the operation shakiness is cut wound very easily.

Description of drawings:

Fig. 1 is the structure chart of transversely cutting cable dermatotome.Wherein: (1)-knife rest; (2)-garden dish cutting knife; (3)-axle; (4)-slide block; (5)-compress leading screw; (6)-operating grip; (7)-by the cable of peeling.

Fig. 2, Fig. 3 are the structure charts of vertically cutting the cable dermatotome open, and Fig. 3 is the end view of Fig. 2.Wherein: (8)-upper handle; (9)-cutting knife; (10)-hinge axis; (11)-lower handle; (12)-fixed wheel of band V-type groove; (13)-by the cable of peeling.

The design's performance is as follows:

The garden dise knife of transversely cutting cable dermatotome is done with the instrument steel, and Quenching Treatment keeps sharp.Screw thread between leading screw and the knife rest adopts M20 * 2.Overall length 300mm, width 110mm, thick 24mm.

The cutting knife of vertically cutting the cable dermatotome open is done with the instrument steel or with the useless saw blade system of tool steel, fixed wheel quenches with 45 steel.Overall length 210mm, width 80mm, thick 80mm.

Claims

1, a kind of cable peeling cutter of being made up of cutting knife and guide device is characterized in that: it forms a cover by transversely cutting cable skin and two knives vertically cutting the cable skin open.
