Description

one

The invention relates to devices for processing wiring wires of electrical and radio engineering enterprises.

There are known devices for measuring cutting, stripping, "tinning of assembly wires, containing a wire feed mechanism, a target conveyor with adjustable: gades for placing the wire, clamping mechanisms, firing mechanisms, and stripping insulation, twisting mechanisms, and shortcuts, fluxing mechanisms and tin and. drive mechanism. However, these devices do not provide high quality processing of wires and have low productivity when processing thick (wires).

To eliminate these drawbacks in the proposed device, the mechanisms for firing, stripping and twisting the current-carrying veins, fluxing and tinning mechanisms are placed in pairs on two sides of the transponder, the sockets of which are perpendicular to its axis of movement and equipped with interchangeable rollers in which body longitudinal grooves of rectangular cross-section, covered with interchangeable plates, are made, and the clamping mechanisms are installed at the firing, stripping and twisting points of the current-carrying cores.

FIG. 1 shows the kinematic scheme of the proposed device; in fig. 2 shows the wire clamping mechanism; in fig. 3 - conveyor, section A-A in FIG. one; in fig. 4 - insulation firing mechanism, BB section in f.ig. one; in fig. 5 shows the twisting mechanism of the strands, sections B-B and D-D in FIG. 1 and the working area of the stripping mechanism; in fig. 6 - wire feed mechanism.

The device contains a shaft. Drive 1, the cam shaft 2, the conveyor 3 with the drive shaft

4, the mechanism 5, the mechanism 6 feeds and wires, installed in pairs on both sides of the transporting mechanism, insulation burning mechanisms 7, insulation removing mechanisms 8, current-driving twisting mechanisms 9, fluxing mechanisms 10, and tinning mechanisms 11 . The mechanisms 7-11 are kinematically connected with the drive shaft 1 by sliders 12, cams 13, brush bars, rails 21. The driven shaft is fixed on the driving shaft 4 of the conveyor 22

the link 23 of the Maltese mechanism, which interacts with the leading (m 31ven 24, fixed. on the cam shaft 2.

The wire feeding mechanism b is driven from the crankshaft 25 and the connecting rod 26. The right mechanisms 7-11 are mounted on the plate 27 moved with the help of the handle 28. At the positions of firing, stripping of insulation and twisting of the current-carrying veins are installed 29 for clamping wires consisting of

mounted on brackets 30

crackers 31, interacting with sliders 32 through levers 33, provided with fingers 34, stem 35, cam 36. Conveyor 3 contains chesia 37, sockets 38, CiMeHiHue. Wheels 39, installed perpendicular to the chains, and interchangeable plates 40. Firing mechanisms The insulation has an instep 41, a mandrel 42, levers with directional prisms 43, a lever 44 with heating elements 45. The opposite ends of the levers 43 and 44 are sleeping 46 and are connected by springs 47, and the angle of their swing is adjusted by screws 48 The voltage to the heating elements 45 is supplied through a collector bores 49 and bristles 50.

The mechanisms for surrounding such veins contain brackets 51, mandrels 52 in inol x 53, flat springs 54, interacting through croutons 55 with tippers 56, Equipped with lugs 57. Fingers 58 rigidly fixed on linoles x 53, interacting with sliders 12. On frames 51 the stops 59 are firmly fixed, and “and the mandrels 52 are pin-shaped 18.

Mechanisms 8 for removing insulation are made similarly to the mechanisms 9 for twisting the cores and differ only in the performance of the working edges on the springs 54 (see Fig. 5, section G – D) and the exclusion of their | Rotation | Nogo motion. The wire feed mechanism 6 comprises a guide 61, a carriage 62, grippers 63 and a spring 64 fixed on the cracks 60, which are fastened.

Works the proposed device as follows.

Set the required length of the crank 25. In the nest 38 of the conveyor 3 install the appropriate rollers 39 and overlap them with an interchangeable plate 40. The handle 28 moves the right side of the device, assembled 27 a, to the distance required to the conveyor. In the baths of mechanisms 10, liquid flux is poured, and in baths of fur of isms, 11 are heated with Solder. From the coil, they charge the end of the wire into mechanism 6. The heating elements in the firing mechanisms and the drive are turned on, and shaft I starts to erupt. The feed mechanism 6. Pushes the wire through the cutting mechanism 5 into. A rectangular hole in the conveyor 3, formed by a longitudinal groove on one m of the rollers 39 and the plate 40. After supplying a piece of wire of a given length, it is cut off, and the lead 24 Maltese mechanism rotates the driven link 23, moving the conveyor 3 one step. The ends of the billet are in the working areas of the insulation firing mechanisms 7. Here, the wire is clamped by the mechanism 29, and through the gears 14, 15, 16, 17 and 20, the firing mechanisms begin to rotate. At the same time, the heating elements 45 and the guiding prisms 43 on the levers interact with the conductor under the influence of centrifugal forces developed by the loads 46. The firing mechanisms rotate by an integer number of revolutions, and after they stop, the wire ends are free and ring-shaped. isolation The conveyor moves still and the pitch and the ends of the wire are in the working areas of the mechanisms 8 for removing the insulation, where the wire is again clamped by the mechanism 29.

With the start of rotation of the gear 17, the cam mounted on it will touch the stop 57, and the rod 56 will move in the axial direction. The working edges of the springs 54 interact

with burnt wire ends. At this moment, from (cams 13 through slides 12 and fingers 58 quills 53 move along the axis and remove annealed areas of insulation from the ends of the wire. After that, the mechanisms for removing the insulation go back to their original position, and the conveyor belt moves again one step. The insulation-free ends of the wires are in the working areas of the twisting mechanisms of the current-carrying veins, where the wire

clamped again by mechanism 29. Mechanisms 9 work, as well as mechanisms for removing insulation, only springs 54 additionally rotate an integer number of revolutions or a multiple of 0.5 and their working edges are rounded.

In this way, the springs 54. In the compressed state obtain simultaneous rotational and translational movements. After the cycle is complete, the mechanisms occupy the original

the position, and the conveyor belt moves the workpiece onto the new pin and transfers it to the fluxing zone, where the mechanisms 10 apply flux to the ends of the wire with brushes swaying from the rails 21 mounted on sliders 12.

After fluxing, the conveyor transports the billet to the zones of the mechanisms of 11 tinning, where the ends of the flux-coated wire are poured with molten solder. After the conveyor is moved one step further, the roller carrying the blank leaves the plate 40 and the treated piece of wire falls into the container.

Operations at all positions are performed simultaneously, and for one revolution of the drive shaft

1 get one piece of treated wire.
