Abstract

The utility model relates to a special tool for peeling-cutting layers of electric insulation wires. The peeling-cutting device for electric insulation wires comprises an upper casing and a lower casing; both end heads of the casing are handles, and thrust caps are sheathed on the outside of the casing; a turning tool bar is arranged in the upper casing, and the front end of the turning tool bar is a square tool rest; a cutter shaft is arranged on the tool rest, and rolling cutters are arranged on the cutter shaft; guide wheels are arranged on both sides of the cutter shaft respectively; a pinch roller frame and a lower pinch roller centre which are connected into integration are arranged in the lower casing; a pinch wheel is arranged on a lower pinch roller frame. The novel peeling-cutting tool can cut and peel hard cross linked polyethylene insulated wires of the insulation layer and the thickness of the insulated wire is longer than three millimeters. The peeling-cutting device for electric insulation wires has functions of carrying out radial and axial peeling and cutting, and has the advantages of neat and accurate cut, without hurting wires, convenient operation, etc.

Description

Electric insulation lead pelling-cutting device

The utility model relates to the insulating barrier stripping unit of lead, particularly the pelling-cutting device of the electric insulation lead that uses in the power engineering construction.

At present, power industry is a large amount of novel conductive wires that adopt in the net system reform of city, it is crosslinked polyetylene insulated lead, its insulating barrier is very hard, and thickness of insulating layer is generally between 3～5mm, the general peeling tools such as common electrician's cutter or other blade that adopt of present unit in charge of construction, effect is very undesirable, and the workmen is in operation because misoperation and scratch lead or cause personal injury, the stripping of electric insulation wire insulation has just become one to be the trouble of the time-consuming gas of requiring great effort again like this, in order to address this problem, people have done multiple effort, the patent that a key name is called " cable peeling cutter " number is disclosed as Chinese patent " 91217146.4 ", introduced a kind of can be with the cutter of the quick strip off of cable skin, by the cutter shell, pressure hook, universal cutter, sleeve pipe, spring and screw are formed, cutter head can rotate, regulate the height of cutter head by screw, rotating knife shell during use, cutter head is cut by equidirectional motion and with cable skin thereupon, again the cutter shell is moved along the cable length direction, at this moment the direction of motion of cutter head also becomes along the cable length direction and moves, when the cutter shell moves to desired location, cable skin is strip off simultaneously also, this device stripping thickness is suitable for less than the common cable of 3mm, because its insulating barrier is very hard, thickness is then inapplicable between 3～5mm for the crosslinked polyetylene insulated lead that uses in the net system reform of power industry city.

Task of the present utility model is: design a kind of simple in structure, safe and convenient to use, specific purpose tool that can divest electric insulation lead external insulation layer fast effortlessly.

Task of the present utility model realizes as follows: pelling-cutting device is linked to each other by hinge by upper and lower casing and constitutes, two ends is that the handle outside is covered with the thrust cap, the toolsetting bar is housed in the upper shell, its front end is square knife rest 7, cutter shaft is housed on the knife rest, rolling blade 8 is housed on it, be positioned at housing, the toolsetting rod outer surface is provided with back-moving spring, by spacing gland location, both sides at cutter shaft are respectively arranged with guide wheel, the pinch roller frame and the lower pressure wheel push rod that fuse are housed in lower house, pinch roller are housed pressing down on the wheel carrier.

The utility model is owing to adopt the clamping of pinch roller bikini to be cut the stripping lead, therefore, to the stripping of electric insulation lead the time, can be along lead radial motion and axial motion, only there are rolling friction in lead and roller in the work, so the resistance of motion is little, and the operator is laborsaving; The utility model is owing to adopt rolling blade that insulating barrier is carried out axially and cutting radially, and resistance is little in working angles, and is laborsaving quick.The utility model is because handle and toolsetting bar are integral, and the turn handle just can be adjusted depth of cut easily and clamp the electric insulation line like this.

Fig. 1 is the utility model front view;

Fig. 2 is the A-A cutaway view of Fig. 1.

A most preferred embodiment of the present utility model, as figure, the upper shell 1 of pelling-cutting device links to each other the one side by hinge 13 with lower house 2 and constitutes holding frame, opposite side can open it and close by valve bolt assembly 4, the two ends of last lower house is a handle, the outside is covered with thrust cap 3, on the thrust cap, have the hole, non-magnetic shim 14 fuses thrust cap and toolsetting bar 6, its front end of toolsetting bar that is positioned at housing is a knife rest 7, be shaped as a square framework, cutter shaft 17 is housed on it, rolling blade 8 is housed on it, this square knife rest matches with square groove on the upper shell, being positioned at upper shell toolsetting bar has a back-moving spring 12 outward, and by spacing gland 5 location, the both sides of knife rest are respectively arranged with guide wheel 9, guide wheel is that the two ends by guide wheel shaft 16 is contained in the groove of upper shell, be equipped with in the lower house 2 fuse press down wheel carrier 10 and lower pressure wheel push rod 11, wheel pressing shaft 15 is housed pressing down on the wheel carrier, pinch roller 18 is housed on it.

The course of work of this device is: at first open the lead that bolt assembly 4 will stripping and put into the pelling-cutting device housing, can adjust lower tumbler according to the thickness of lead rotation lower house handle makes two upper blocks and a lower tumbler form with electric wire at 3 to fix, just can adjust depth of cut according to the thickness rotation upper shell handle of electric wire insulation layer then, hold, lower handle makes pelling-cutting device do radial motion on insulated conductor, just the lead external insulation layer radially can be cut, open valve bolt 4 then and press down handle and make the back-moving spring compression, make knife rest 7 skid off chamber, upper shell side and rotate 90 ° of angles, release lever leans in the chamber, the elastic force side of getting back to of back-moving spring knife rest, finish the purpose of commutation, to go up, lower house heals up and locks valve bolt 4, hold handle and make pelling-cutting device do axial rotation again, just wire insulation is cut off.
