Description

The cutting stripping means of cable end insulating barrier and the key tool used thereof

Technical field

The cutting stripping means that the present invention relates to high-voltgae pothead insulating barrier and the structure technology of crucial specific purpose tool used thereof.

Background technology

At present, when utilizing electrician's knife to peel off polyethylene layer in high-voltgae pothead manufacturing process, first, profit electrician's knife or similar means along the polyethylene layer of wire periphery circumference and centripetal around cutting (position to core conductor place), then, the cable end direction of peeling off along the center line of high-tension cable length towards this wish is again to core straight cuts (position to core conductor place), finally, pull out the polyethylene layer for peeling off on this cable, so far, the stripping operation of this cable polyethylene layer is all completed.

Obviously, in the overall process of above-mentioned stripping, the instrument that can use is very limited, moreover the physical attribute of insulating barrier itself (thickness is large and intensity is high and be rich in toughness), causes sizable trouble to again above-mentioned stripping operation.

Summary of the invention

The object of the present invention: be exactly solve above-mentioned " sizable trouble " problem.

In order to realize the object of the present invention, intend adopting following technology:

The step that cutting stripping means of the present invention at least comprises:

First, need the cable peeling off head insulating barrier to be positioned on the non-live ejector half fixture of such as bench vice one class by exposing it: such as, by the arc that is arranged on fixed bench vice and the chucking surface with Nail dentation decorative pattern clamp and clamp cable;

Then, Special cutting tool being packed into above-mentioned cable head for cutting position has carried out the cutting process to this insulating barrier by the mode of limit rotation limit feed: such as, by iterative method hobboing cutter and for the center of circle rotates, whole specific purpose tool realizes by circumferential anxious program of cutting insulating barrier with the cable core (wire) in cable;

Finally, insulating barrier cutting by above-mentioned cutting process is stripped down, cable head can be allowed to expose naked cable core (wire): longitudinally to be lancinated again insulating barrier by manpower (such as: hold cutter straight line draw cut) or electric power (such as: available electric hand drill drives and rotates profile of tooth saw blade straight line saw) mode, the cutting of the insulating barrier of cable head stripped down.

The crucial specific purpose tool utilized when the present invention relates to strip cable head insulating barrier:

To be positioned on U-shaped tool body by bearing and hobboing cutter for cutting the insulating barrier forming cable; Also comprise:

Be positioned at and U-shaped tool base can extrude cut cable and need the cable jacking roller of released part and determine the lockable mechanism of cutting end point;

Described cable jacking roller becomes mated condition by jacking mechanism with U-shaped tool base, and this jacking mechanism and U-shaped tool base can be locked by feed blocking bolt;

The traveling process of described cable jacking roller regulates screw mandrel to promote jacking mechanism by feed and indirectly drives;

Described lockable mechanism is by regulating screw mandrel to determine the cutting end point position of lockable mechanism on U-shaped tool body.

The cable jacking roller of----described is connected with jacking mechanism by wheel carrier.

The U-shaped tool body of----described, the lockable mechanism groove bottom it can allow feed blocking bolt extend there through, and this lockable mechanism slot length size is greater than the diameter of the thickest specification cable.

The present invention's feature compared with the prior art:

Technical pattern and the using method thereof of exfoliation tool is cut owing to by means of the cable insulation (such as: polyethylene layer) proposed in the invention described above, this is just for utilizing specific purpose tool that cable insulation is stripped down the condition of creating from cable core (wire) reserve part of cable end very easily and easily, is and very easily and easily allows the wire in cable realize externally connecting creating condition.

Embodiment

The inventive method of strip cable head insulating barrier is very simple, and the step at least comprised in brief is as follows:

First, location will be implemented for cutting cable head insulating barrier at cable;

Then, private cable is utilized to peel off the cutting process of specific purpose tool complete paired cable P insulating barrier P1;

Finally, the insulating barrier P1 of the cable P head cut down is got off from drawing (stripping) this cable P.---specifically refer to explanation relevant in " summary of the invention " paragraph.

The key tool structure performing said method is also uncomplicated, wherein:

U-shaped tool base 1 adopts the milling of Q235 high strength steel material to make.

Being positioned at the hobboing cutter 2 in U-shaped tool base 1, is be positioned at the end of U-shaped tool base 1 by bearing 0.

The Main Function that feed regulates screw mandrel 6 and jacking mechanism 7 one-tenth anteroposterior position to move matching relationship is feed, at cable jacking roller 3 and the hobboing cutter 2 being fixed in U-shaped tool base 1 of attached cable P, implement cutting action by the slide displacement in U-shaped tool base 1, cable jacking roller 3 is fixed on jacking mechanism 7 by wheel carrier Q.

The present invention adopts when determining that the main purpose of the lockable mechanism 5 of cutting end point is and avoids strip cable insulating barrier and injures conductor; For 10kV cable, the thickness of insulating barrier is 4.5mm, lock feed locking screw mandrel L2 before cutting, by regulating the adjustment screw mandrel L1 determining the lockable mechanism of cutting end point, to determine that the lockable mechanism 5 of cutting end point inwardly regulates 4.5mm along fixing scale index 4, then feed locking screw mandrel L2 is unclamped, till regulating screw mandrel 6 to be cut to the lockable mechanism 5 withstanding and determine cutting end point by rotation feed.

Above-mentioned key tool operation principle is structurally few in the formation of parts, what therefore the volume of its entirety can be made is very little, manually this Special cutting tool can be operated completely by artificial, complete with the cutting mode of circumference concentric contraction, the head insulation layer P1 of cable P is implemented the cutting of effective section.
