(54) DEVICE FOR MEASURING CUTTING WIRES AND REMOVAL FROM INSULATION END

one

This invention relates to a process equipment for measuring wire cutting and stripping insulation from its ends and can be used in the electrical industry.

A device for measuring wire cutting and stripping from the ends of an insulation is known, comprising a housing on which mechanisms for leveling, feeding and clamping wires located on the carriage, cutting the wire and stripping insulation 1 are installed.

A disadvantage of the known device is the curvature of the processed wire between the feed carriage and the clamping wire and the leveling mechanism, which degrades the quality of the wires to be made.

The purpose of the invention is to improve the quality of the wires produced.

This goal is achieved by the fact that the device contains an additional movable carriage mounted in the housing and spring-loaded to it with an abutment in contact with the carriage of the wire feeding and clamping device, and the leveling mechanism is located on the additional carriage.

FIG. 1 shows the proposed device, a general view; in fig. 2 - mechanism

straighteners, located on an additional carriage; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 1 (feeder and wire clamp with unclamped); in fig. 5 - the feeder and clamping wires with open gripping and closed knives; in fig. 6 is a view of B in FIG. one; in fig. 7-10 are diagrams of a sequential process of measuring wire cutting and stripping.

The device for measuring wire cutting and stripping from the ends of the insulation (Fig. 1) comprises a frame 1 with a coil 3 installed on an axis 2 for a coil of the wire being processed, a guide roller 4 mounted on a lever 5 spring-loaded to the frame 6, body 7 Equipped with a distribution mechanism 8, on which the guides 9 of the feeder and wire clamping mechanism are fixed, the cutting mechanism 10 and the bracket 11, on which the additional carriage of the torque tool is mounted for longitudinal movement. On the guides 9 with the possibility of reciprocating motion, a carriage 12 of the feeder and wire clamping mechanism is installed and bearing bearings are fixed

nodes 13 and 14, in which a square shaft 15 is installed. The carriage 12 is provided with a sleeve 16 with a square hole in which the shaft 15 is freely located. The sleeve 16 is made with a protrusion 17 (FIG. 4), which is pivotally connected to the driver 19 through the shackle 18. Gears 20 and 21 are mounted on the carriage 12 with gearing. A lead 19 is pivotally connected to gear 21. Swivel arms 22 and 23 are pivotally connected to gears 20 and 21 and one arm with earrings 24 and 25. Other arms of arms 22 and 23 are equipped with clips wires A follower 26 is fixed on the axis of gear 2Q and fixed (Fig. 1). An additional carriage 27 is mounted on the bracket 11, on which the straightening mechanism is located and which is spring-loaded relative to the housing in the wire feed direction by the spring 28. The carriage is equipped with straightening rollers 29, with an eccentric sector 30 pressed to the torque roller 31 by the spring 32 (Fig. 2 and 3 ). On the carriage 27, there is an abutment 33 in contact with the pusher 26. The cutting and stripping mechanism at the ends of the wire contains slides 34 and 35 on which the knives 36 for removing the insulation and the knives 37 for cutting the wire are attached.

The length of movement of the carriage 12, the angle of rotation of the shaft 15, the distance between the sliders 34 and 35, and the distance between the blades 36 and 37. is set depending on the diameter and the specified length of the wire to be cut, as well as on the length of the wire section, which is exempt from insulation. Drives for moving the carriage 12, rotating the shaft 15 and moving the sliders 34 and 35 are located on the distribution mechanism.

The device works following us.

 The wire 38 is passed through the roller 4 of the lever 5, smoothing jerks when feeding the wire, as well as providing braking coil 3 at the lower extreme position of the lever (brake not shown). Next, the wire is passed through the rollers of the adjusting mechanism (Fig. 2) and by turning the shaft 15 through 90 °, the wires are clamped with levers 22 and 23 (Fig. 4).

The device works in automatic mode. The carriage 12 with the clamped wire moves from left to right, the passage through the open knives 36 and 37. After a certain length of wire has been measured, the carriage stops. The drive of the sliders 34 and 35 is actuated, the knives 36 and 37 approach each other. Average

a pair of knives 37 cuts the wire, the extreme pairs of knives 36 cut the insulation. In this case, the carriage 12 is reported to be accelerated moving to the right, tearing off the insulation from the end of the cut wire (Fig. 8). After that, the levers 22 and 23 are consumed (FIG. 5), freeing the cut wire (FIG. 9). The carriage 12 returns to the extreme left position until the push rod 26 touches the stop 33 of the carriage 27 of the torque mechanism (Fig. 9). The wire is clamped again and the carriage 12, making an accelerated movement to the left, pulls off the insulation from the wire to be measured (Fig. 10). In this case, the carriage 27, supported by the pusher 26, moves together with the carriage 12, excluding the bending of the wire

between them. After removing the insulation, the knives 36 and 37 open, and the carriage 12 moves in the direction of the working stroke, measuring the predetermined length of the wire, and the carriage 27, returning to the starting position under the action of the spring 28, stops, passing

through the rollers 29 and 31 and the sector 30, the wire has been altered The process then repeats.

The effectiveness of the proposed device in comparison with the known ones consists in eliminating the curvature of the wire being processed by performing an additional movable carriage installed in the housing and spring-loaded to it with an abutment in contact with the carriage of the feed and clamping wire and located on the additional carriage of the TOBKHi mechanism.
