Abstract

The invention relates to the technology of preparation of electrical wires for installation and can be used by electrical and radio engineering branches. The purpose of the invention is to expand the technological capabilities by providing wire processing according to a predetermined program. The method consists in winding the treated wire 1 with the charging coil into the treatment zone. The electric heater is displaced to the continuous section 3 to the contact with the heated contact surfaces and makes a running around the insulation perimeter, as a result of which one surface of the heater uses the contact heat transfer method to burn off the insulation in the middle firing zone 9, and the other contact surfaces of the electric heater Ring cuts 10 and 11 along the entire perimeter are made at the borders of the isolation area. Sections 12 and 13 of the insulation are shifted to the middle zone 9, while the shearing of the segments 12 and 13 of the insulation, fluxing and tinning of the core 14 are performed simultaneously as the insulation burns out in the middle zone 9. 1Cp. f-ly. 6 Il.

The processable wire 1 is wound from the charging coil to the treatment zone. Electric heater 2 is moved to the processed continuous section 3 to contact with heated contact surfaces 4-6 at point 7 and move around the perimeter of insulation along arrow 8. Surface 4 of electric heater 2 by contact method of heat transfer burns off insulation in the middle zone 9 roasting. The contact surfaces 5 and 6 make annular cuts 10 and 1 along the entire perimeter at the edges of the insulation. Sections 12 and 13 of the insulation with the jaws of the automaton are shifted to the middle zone 9 along the core 14, to the bare, non-oxidized areas 15 and 16, flux fluxes and solder are moved and the process of tinning is performed. In this case, the shearing of the segments J2 and 13 of the insulation, fluxing and tinning

The cores 14 are performed simultaneously as the insulation burns out in the middle zone 9.

Further processing consists in rewinding the wire to the receiving coil 17 for a programmable length and repeating operations with a new wire insulation section. The repetition of the operations is carried out until

will not be prepared and reeled on the coil 17 all to be laid in the set harness measuring jumpers and. Laying - wire in a plait harness - 3 lengths of P1, insulated lengths 18 between the trimmed sections 16 and 19 on the coil 17 are performed. Cutting the wire into measuring segments 20 is carried out along the boundaries

the trimmed areas of the veins, and the middle firing zone 9 with segments 12 and 13 of the insulation are removed.

Claims (2)

When processing the wire by the welding torch block 21 (for example, the mount of the welding equipment of the electrolysis-water installations), the firing and incision of the insulation is carried out with only one transverse return-movement movement of the burner block 22. At this flame 23 of the burners 22 processes the middle Zone 9, flame pairs 24 and 25 of the burners 22 cut the insulation. The burners in pairs 24 and 25 are arranged at an angle of 26 to one another, and during reciprocating motion, segments 12 and 13 of insulation along the perimeter are separated. The thin shadow residue 27 of the insulation in the middle firing zone 9 does not have a significant effect on the preparation of the wires, since when shearing the sections 12 and 13 of the insulation to the middle firing zone 9, it forms a loop, which can later be used as an element counting the length of the wire for processing the next section of isolation. Claims. 1, Method of preparing electrical wires for installation, consisting in incision of insulation, shear of the insulation section along the core, fluxing, tinning of the core and removal of part of the core with the remainder of the insulation, which differs in order to expand technological capabilities by providing wire processing according to this program, cutting the insulation along the perimeter of the continuous wire section, in the middle zone of this area, isolate the insulation t in the middle zone 2. A method according to Claim 1, characterized in that the incision of the insulation is carried out by firing, and the shift of the insulation sections, fluxing and tinning of the cores are performed simultaneously as the insulation is burned out in the middle zone. 0 five 0 five 0 five Uz.i fi. 23 2tf . five 25 7J 17 FC VNIIPI.
