(54) DEVICE DLP REMOVAL INSULATING COATING

The invention relates to the laying of cables and the wiring of a transmission line, and is intended to remove the insulation coating from the ends of the wires and can be applied in instrument-making electrical engineering and radio engineering industry.

A known machine for cleaning wires from insulation, comprising a knife head, seated on the shaft of an electric motor, in the casing of which there are fixed diametrically movable knife blocks that carry. knives. The blocks can move from the screw,

. having a right and left cut 13. The disadvantage of this machine is the impossibility of adapting to different wire diameters due to the rigid fixation of the knives. It is also known a device for stripping the ends of wires, comprising a housing associated with a drive of its rotation, and cutters installed inside the housing, as well as stops made in the form of discs with a spherical side surface and pressed into the housing with a side surface Spheres, on the one hand the cutting edge.

and on the other, the bearing surface in contact with stop C2.

Significant disadvantages of this device are a rigid adjustment to one fixed size due to the geometry of the incisors and the stop and, as a result, the need to use several cutting heads for each value, due to the tolerances on the diameter of the wire. In this case, a change in the geometry of the incisors as a result of normal wear and tear requires frequent stopping and adjustment of the geometry of the working gap. Besides.,

15, the device does not allow the removal of a solid insulating film with a small wire diameter, since longitudinal deformation of the wire occurs, as a result of which it is not possible to feed the device, the cutters are placed in the same plane in a plane, leading to a significant increase in the wire insertion force device that is unacceptable for wires of small diameter 25 pa.

Claims (2)

The disadvantages of the known device also include the difficulty of manufacturing and re-adjusting (fitting) the cutting surfaces, as well as the technological complexity of regrinding the cutters and installation by dismantling the latter with the replacement of the gasket. The purpose of the invention is the expansion of technological capabilities for processing wire of various diameters and the possibility of stripping insulation from different types of wires. The goal is achieved by the fact that a device for removing an insulating coating containing a core associated with a drive of its rotation NIN and a cutter mounted inside the body additionally contains a centrifugal mechanism in the form of a biased load mounted on the body, a sleeve with a face , made to a depth equal to the radius of the sleeve, installed inside the body, the bracket, the shelves of which are located around the body, and the heating element, mounted coaxially to the body, while the knife is made with a sharp angle of 90-100 ° located The inside of the sleeves of the sleeve is connected to the clip and the clip is mounted with the possibility of movement in the direction perpendicular to the supply of the wire, and is connected by two spring-loaded weights. In addition, the device includes a valve for transferring movement from the knife bracket to the center of the sleeve and a latch for reversing the knife movement, with a slot made in the knife, the valve and the latch secured to the knife groove, and the valve at the knife end. Figure 1 shows the proposed device, a General view, section; figure 2 - section aa in figure 1; fig.Z - node I in figure 1; Fig.4 section bB in Fig.Z. In the protective casing 1, an electric motor 2 is mounted, on which shaft the housing 3 is mounted, in the head part there is a sleeve 4 with a face, in which there is a cutter 5 connected by means of a valve 6 and a latch 7 with a clip 8 connected to the load 9 by means of pins 10. The end of the head part of the housing 3 is closed by a cover-flange 11. The load 9 is fixed by screws 12 and spring loaded by the return spring 13. Outside the protective casing 1 coaxially with the axis of the housing 3 and the axis of the electric motor 2, there is a heating element 14 and a funnel 15 intended for centriro The vanes of the processed end of the wire 16. Weight-balancer 17 is fixedly mounted on the housing 3. Positions 18-21 of the child are fastening. The device works as follows. , - The end of the wire 16 is freely inserted into the device axially through the guide funnel 15 and then supplied through the switched on heating element 14 and the sleeve-bush 4 until the end of the motor stops. After that, the electric motor 2 is turned on and the heating element 14 is turned off. The load 9 is rotated on the screws 12 by the centrifugal force and acts on the cutter 5 through the pins 10 and the clamp 8. Thus, the cutter is fed to the insulating coating of the wire through the groove of the bush 4 .A withdrawal of the drive being processed from the device removes the insulation coating. After the motor 2 is turned off, the cutter 5 and the load 9 return to their original position due to the action of the return spring 13. Then the cycle is repeated. The cutting edge of the cutter 5, located at an angle d to the axis of the wire, ensures constant contact with the wire surface regardless of the diameter of the wire and its relative position in the groove of the bush, as well as the accuracy of manufacturing and sharpening the edge of the cutter, and the selected point angle jp cutter 5 with a magnitude of 90-100 ° C provides cutting gab that allows the removal of a minimum layer of conductor metal with a high degree of purity. Thus, the proposed device makes it possible to efficiently remove an insulating coating without restructuring and adjusting the wire with a diameter of from E to 2dt. Claim 1. A device for removing an insulating coating, comprising a housing associated with a drive for its rotation, and a cutter mounted inside the case, characterized in that, in order to expand technological capabilities by treating wires of different diameters and isolating various brands, it contains a centrifugal mechanism in the form of a spring-loaded load, mounted on the housing, a sleeve with a flat face made to a depth equal to the radius of the sleeve installed inside the body, a bracket whose shelves are located around the body and a heating element mounted coaxially to the body, while the knife is made with an angle of 90-100 5 point bushings and associated with the bracket, and the bracket is installed with the ability to move in directions perpendicular to the wire, associated with a spring-loaded load. 2. The device according to claim 1, which includes the valve for transferring movement from the knife to the center of the sleeve and a latch for reversing the movement of the knife, while the knife has a groove, the valve and the latch are fixed on: the bracket, the latch is located in the knife's slot, and the valve is located at the end of the knife. / Sources of information taken into account in the examination No. / 7G ff il at l 1 / g 1, Patent IT O 3537339, cl. 81-9.51, opuLayk. 1970. 2.
