Abstract

The invention relates to electrical engineering and is intended to automate the operation of bending and twisting of loops (rings) at the ends of electrical wires. The aim of the invention is to automate the twisting processes. The goal is achieved by inserting the clamping jaws 22 into the device, and the base 2 is equipped with brackets 30 mounted parallel to the housing 3. After stopping and fixing the drum 32 accurately, the base 2 moves in a direction radial to the drum 32. In this case, the end of the electrical wire 10 enters the gap between the mandrel 8 and the pin 5. The device provides bending and twisting of the loop on the electrical wires in the automatic cycle. 6 Il. 3 No. / JWWrl / / IT SL from 00 7 / / / /. ; / к} 5 15 Ю 8 5 B from Figure 1

Description

The invention relates to electrical engineering and is intended to automate the operation of bending and twisting of loops (rings) at the ends of electrical wires.

The purpose of the invention is to automate the twisting process.

FIG. 1 shows a device for bending and twisting loops at the ends of electrical wires, a general view; in fig. 2 is a view A of FIG. one; Fig. 3 is a section B-B of Fig. one; in fig. 4 — node I in FIG. 1, after bending the end of the wire into a loop; in fig. 5 - the same, after twisting the loop at the end of the wire; in fig. 6 is a sectional view BB in FIG. one.

The device consists of a frame 1 on which the base 2 with the housing 3 is located. In the opening of the housing 3, an element for bending the end of the wire (sleeve) A is installed with an eccentrically made pin 5. The sleeve 4 is axially fixed by a spring ring 6 on the sleeve 4 is fixedly fixed toothed gear 7. A mandrel 8 is axially displaced in the hole in sleeve 4, forming the inner diameter of electrical wire loop 9 10. Rotating sleeve 4 with pin 5 is driven (electron., Pneumatic). or hydraulic cylinder) 11 with a toothed rack 12 meshed with a block of gears 13, which is connected to gear 7 by gears 14. The rack 12 is supported and guided by rollers 15. The mandrel 8 is moved by a drive 16 connected to a mandrel 8 with a double-arm lever 17, the housing 3 is mounted in the opening of the base 2 with the possibility of reciprocating rotation, and on the rear side of the base 2 by gear 18 it is connected to a rack and pinion drive 19. The rail 20 is supported and guided by rollers 21. On the base 2 it is fixed ene stationary yaw 22 with a bevel 23, serving to guide the wires and the movable jaw 24 by pivot zafiksirovanna finger 25. At the contact portion of the movable jaw 24 is formed sticker 26 of elastic material (e.g., polyurethane, hard rubber, etc.). The movable sponge 24 presses against the fixed sponge 22 under the action of a spring 27, adjustable

the threaded barrel 28, and is retracted by the actuator 29, fixed to the base 2 by means of the bracket 30. The electrical signals for controlling the actuators 11 and 16 are supplied through the rings 31 or simply through the connecting harness in the process of reciprocating rotation of the housing 3 is wound and unwound. The electrical wire 10, mounted on the supply drum 32, is preliminarily cleaned of isolation, passes the stranding of the strands at the respective positions of the machine (not shown).

The device for bending and twisting the loops at the ends of the electrical wires works as follows.

The electrical wire 10 to the bending and twisting position of the loop 9 is supplied by the drum 32 with the finished end (at the previous positions of the machine). After stopping and precise fixing of the drum 32, the base 2 moves in a direction radial to the axis of the drum 32 (arrow G, Fig. 6). The end of the electrical wire 10 enters the gap between the mandrel 8 and the pin 5. After that, the actuator 11 and the sleeve 4 with the pin 5 turn on, turning around the mandrel 8, the end of the electrical wire 10 is bent into the loop 9. Then the drive 29 turns off and the movable the sponge 24 under the action of the spring 27 fixes the formed loop in the corresponding position (Fig. 4). Further, the actuator 19 of rotation of the housing 3 is turned on and the loop 9 is twisted, and then the mandrel 8 is pulled out of the loop 9 by the actuator 16 and the base 2 is retracted.

The device provides bending and twisting of the loop on the electric wires in the automatic cycle, increases labor productivity and product quality.

A positive effect is achieved by automating the stranding process.
