Abstract

The utility model discloses a wire stripper, which is mainly arranged below the punch press of a terminal machine. A rotating main shaft is arranged on one side of the machine body. A cam wheel and a slant cam wheel are respectively arranged on the rotating main shaft. A movable machine table is arranged on the other side of the machine body. An oscillating rod is arranged between the movable machine table and the slant cam wheel. One end of the oscillating rod is butted on the slant cam wheel, and the other end of the oscillating rod is movably engaged on the movable machine table. When the main shaft rotates, the oscillating lever can do to-and-fro motion. The other cam wheel of the main shaft is a cutter mechanism butted on one end of the movable machine table, so the cam wheel is intermittently butted on the cutter mechanism to do the ring cutting on the outer skin of electrical wires. The outer skin can be removed to match the punching work of the terminal machine when the movable machine table moves backwards.

Description

Wire stripper

The utility model relates to a kind of apparatus for peeling off of terminal machine, mainly be to there is no apparatus for peeling off mostly at existing terminal machine, so before beating terminal, must remove the crust of electric wire earlier with manual type, place terminal machine below punching press in the mode that manually holds again, in operation, very bother, idol has apparatus for peeling off in addition, the length and the wire thicknesses difference that all can't control peeling then can't be adjusted cutting, so many inconveniences are arranged in the use, so the apparatus for peeling off of a kind of delicate structure of ad hoc meter can very easily be operated the work of finishing the electric wire peeling.

A kind of very easily part when terminal is the supply lines binding, it mainly is that mode with punching press is riveted on the inside bare wire of electric wire, its working procedure be with electric wire in artificial mode (as with pliers or blade) with its epidermis ring cutting, ring cutting but still the epidermis kept somewhere on electric wire are outwards extracted with this with pliers again, then electric wire promptly exposes one section wire termination of shelling skin, place the drift lower end of terminal machine to overlap the work of terminal and punching press the exposed end of this electric wire, like this then can finish the work that terminal is fixed in electric wire, wherein because the peeling work of electric wire is to carry out in artificial mode, so can't produce in a large number, and artificial removal's electric wire epidermis (outwards pulls out as cutting electric wire with the pliers folder because of the size of the application of force sometimes again, to remove the epidermis of no complete ring cutting), and produce because of one section of the excessive electric wire section of cutting soon of the application of force, or can't smoothly the electric wire epidermis be removed because of the application of force is too little, not only lose time in the electric wire epidermis pullling to remove, also injure simultaneously the lead of electric wire inside easily, be to be a kind of very unscientific peeling mode, so before the terminal steady job, the device that automatic stripping electric wire epidermis should be arranged can make the work of the preceding removal electric wire epidermis of fixed terminal (or other) more convenient.

Main purpose of the present utility model is to provide a kind of apparatus for peeling off of terminal machine, make it be provided with a rotary main shaft, be respectively equipped with two cams on it, other establishes a movable board, end at movable board is provided with cutter mechanism, the relative action of this cutter mechanism is to adjust nut control, and nut is to be butted on a cam, then the profile according to cam can push against the side blade relative shear that the adjustment nut makes cutter mechanism, between another cam of main shaft and movable board, establish a swing arm, the one end is subjected to the surface of this cam and shaft is done moving partially, then swing arm is the axle center with central authorities, end is that may command activity board moves towards certain direction back and forth along track with movable board pivot joint in addition, with the epidermis pull-off with the ring cutting electric wire.

Another purpose of the present utility model is to provide a kind of apparatus for peeling off of terminal machine that its adjustment nut spiral shell at cutter mechanism is located on the screw rod, the then displacement on screw rod, it promptly is the distance of adjusting between the relative cam of nut with it, then to push the displacement of nut promptly be the depth of cut of cutter mechanism to cam, promptly because of the different degree of depth of adjusting ring cutting of thickness of electric wire.

The purpose of this utility model is realized by following technical scheme.A kind of apparatus for peeling off of terminal machine, wherein be provided with a main shaft, this main shaft one end and power join, end then is installed with a cam and an oblique cam respectively from outside to inside in addition, movable board joins in the track of both sides and body, be provided with at its outboard end and compressed the cutter mechanism that promptly suits relatively, this cutter mechanism is provided with two distance controls that are subjected to a screw rod can make the relative involutory and side blade of cutting electric wire;

Between main shaft and movable board, be pivoted with swing arm with central shaft, the one end is established a slotted hole, and be through at pin and wherein be fixed on the movable board, in addition end then is provided with a kink with roller, wherein roller is to contact with oblique cam, set firmly one in addition on the kink top as the power spring of replying, when the main shaft turn, its terminal cam can push against screw rod and two relative side blades are shear action relatively, be the action of cutting electric wire outer shroud herein, in addition oblique cam is in turn, the roller of swing arm is the deflection with its inclined-plane gradually, can make holding drive activity board to move inward in addition the electric wire epidermis pushed and extracting of actuating strut, be provided with oblique cam and roller to be supported amplexiform and touch and make the spring drawing structure of mobile swing arm homing.

The purpose of this utility model can also further be realized by following technical scheme.The apparatus for peeling off of aforesaid terminal machine, wherein cutter mechanism is to form as a V-notch in the end at two side blades, and after the otch of two side blade ends is involutory, promptly form cross bore as prismatic, this two side blade is to join with one L shaped and a long piece respectively, and the length of the two is held row level with both hands, the sidepiece of this long piece one end and side blade affixed and in addition end join with a screw rod, be pivoted with an inclined to one side motion block at L shaped and long interblock, these inclined to one side motion block central authorities establish jack-post it are articulated on the movable board, during cam control screw displacement, can make moving partially bar is L shaped and microscler relative drawing that rotating shaft articulates two ends with central authorities, and then the affixed side blade of its side promptly is the structure of shear action relatively.

The apparatus for peeling off of aforesaid terminal machine, wherein tiltedly cam face one side is the plane, and side then is an inclined-plane in addition, and the end on the inclined-plane is formed with wing tip again.The apparatus for peeling off of aforesaid terminal machine, wherein screw rod is respectively equipped with one in terminal and central authorities the spacing between nut and cam is adjusted, then the size of may command cross bore and adjust the adjustment nut of the epidermis of cutting different thicknesses electric wire.
