(54) DEVICE FOR BURNING AND REMOVING INSULATION FROM MOUNTING LAYERS

I

The invention relates to the technology of installation of radioelectronic equipment, in particular: to technological equipment for preparing the installation wires for installation and can be used in the electrical, radio engineering and instrument-making industries.

A known automaton for insulating firing, twisting wires and cutting assembly wires, contains firing blade knives, a twisting mechanism made in the form of two clamps installed rotatably in opposite directions relative to knives 1}.

A disadvantage of the known automaton is that the firing knives in the process of firing the insulation of the wire all the time in contact with conductive wires and have a thermal effect on them, leading to damage to the cores.

Closest to the invention is an automaton for firing insulation with cutting wire that contains firing elements, made in the form of plate knives, connected with the drive of their movement in the direction perpendicular to the wire through the double-arm lever and the wire spinning mechanism (21.

However, in this automaton, during the twisting of the wire, the firing elements come into contact with its conductive wires and have a thermal effect on them, which leads to damage to the wires, which reduces the quality of processing of the installation wires.

The purpose of the present invention is to improve the quality of processing of installation wires by eliminating the thermal effects of firing elements on the conductive wires of the wire when it is twisted and reduced

15 impacts in the process of firing insulation.

The goal is achieved by the fact that the mechanism for twisting the wire is made in the form of a slider mounted for movement in the direction perpendicular to

30 to the wire and the spring-loaded platform installed with the possibility of moving in the direction perpendicular to the plane of the slide, while the slide and the platform are kinematically connected with the drive of moving the knives

The drawing shows a kinematic diagram of the device.

The device contains firing elements lamellar knives 1 and 2 mounted on levers 3 and 4 located on axles 5 and 6 and controlled by a cam 7 of a drive mechanism (not shown). The lever 3 has an abutment 8 which cooperates with a slider 9 mounted to move in the direction perpendicular to the wire 10. The platform 11 is spring-loaded 12. The platform I is installed in the guide element 13 that can be moved relative to the slide 9 in the direction perpendicular to its plane of movement by means of a lever 14 interacting with a cam 15. A spring 16 serves to return the slide 9 to its original position. Isolation from the end of the wire 10 is removed by the mechanism 17.

The device works as follows.

When the cams 7 and 15 rotate from a drive (not shown), the levers 3 and 4 rotate on axles 5 and 6, the knives 1 and 2 approach, touch the wire 10, insulate it and burn it. In this case, the stop 8 of the lever 3 and the slider 9 to the right and the wire 10 is scrolled on the platform 11. Thereafter, the platform 11 is retracted from the slider 9 by the lever 14, which interacts with the cam 15. When the knives 1 and 2 reapproach, the spring 9 returns In the initial position, and at the end of the working stroke of the levers 3 and 4, the platform 11 is led to the slider 9 by the lever 14, turning the cam 15. The wire 10 is held by the slider 9 and the platform 11, and its insulation is burned by the knives 1 and 2 in the next section. For several repeated runs, faceted firing of the wire insulation is carried out, which is practically annular. Removing insulation from the conductive wires of the wire 10 is produced by the mechanism 17

The proposed device provides the ability to twist the wire in the interval of the firing knives withdrawal cycle from the wire insulation and bring the knives closer to the wire insulation, stepwise firing of the wire insulation with alternating heating and cooling of the conductors of the cores.

The use of a device for firing and stripping insulation from the ends of the wiring leads eliminates the thermal effects of the firing knives on the conductive wires of the wire during its twisting and significantly reduces them when the insulation is baked, and thereby eliminates the cause of the thermal damage to the conductive wires.
