Description

The invention relates to devices for winding welding wire of predominantly large (3 m and more) diameters from coil to coil and can be used in cores where automatic submerged arc welding is used, for example, in boiler building, petroleum and chemical engineering.

Known devices for winding welding wire on a coil, Containing a paral wire stacker with a filler that receive reciprocating movement from the drive through the cam lj,

The main disadvantage of these devices is the unregulated nature of the stroke of the stacker across the width of the coil, since this value is rigidly defined by the cam profile.

Wire rewinders are known in which the stroke length of the stacker, executed in the form of a slider and connected with the lead screw, is determined by the position of the adjustable stops, which interact with the end switches, which ensure the slider reyers to the extreme positions 2J.

Closest to the present invention is a device for winding a welding wire onto a coil comprising a frame, a coil holder, a coil for a wire and a wire stacker consisting of a carriage with a holder, a lead screw with a nut and a limit switch connected with the reversing mechanism.

The disadvantage of this device with regard to rewinding of a wire of large (3 mm and more) diameter is the unreliability of the device and the poor quality of the wire pulling. I

The purpose of the invention is to improve the quality of wire laying and reliability of the device.

This target is achieved in that the device for winding the welding wire onto a coil comprising a frame, a holder, a wire coil and a wire stacker consisting of a carriage with a holder, a nut screw and limit switches associated with the mechanism reversing, the stacker is equipped with adjustable stops installed on both sides of the carriage, and a nut placed with the ability to move on the spindle on the spindle, and the limit switches are made in the form of probes mounted on the ends of the carcass from its inside.

FIG. 1 shows a device, a plan view; in fig. 2 is a section A-A in FIG. 1; in fig. 3 view B in FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 a, b. in - section G-G in FIG. 3 in three positions.

The device for rewinding the welding wire to the coil consists of the frame t, the coil holder 2, the device 3 for cleaning the wire of the coil 4, one of the walls of which is removable, the drive 5 of rotation of the winding ram, the chain transmission 6 connecting the winding spindle with the reducer ,; The casing 8 houses a wire stacker in the form of a carriage 9 with a guide bushing 10, a lead screw 11, directed toward the center 12, a nut 13, adjustable supports 14 and 15 with lock nuts 16; the lead screw 11 is associated with a reversal mechanism consisting of a bevel gear 17 and a gear gear unit 18, movable along a shaft 19 with a key 20, a double acting pneumatic chamber 21, and a lever 22; Probes 23 and 24 are installed at the walls of Katuapsi 4, connected to galette type switches 25, which are electrically connected to a distributor (not shown) supplying compressed air in the cavity of the pneumatic chamber 21, the working surface of the probes in cross section (horizontal sections) is slightly more than half a diameter rewired wire.

The device works in the following way.

The carriage 9 is installed in the extreme, for example, the left (from the side of the Bay holder 2) position. Wire pins | Ay through the cleaning device 3, the straight sleeve 10 and its end is hidden on the coil 4 at the left wall, I turn the coil one turn, laying the coil of wire close to the wall of the coil; probe 23 is placed on this coil, and probe 24 is placed on the surface of the coil, 4; include drive of the winding spindle; this rotation by means of the chain gear 6 through the reduction gear 7, the gear unit block 18 and the gear wheel 17. is transmitted to the lead screw 11; the nut 13 moves to the right (Fig. 2) and interacts with the stop 15; the carriage 9 is moved to the right in the RD rotation of the spike by the size of the wire diameter (Fig. 5a). Having reached the right wall of the coil 4, the wire, by an extreme turn, raises the probe 24 j, while advancing or delaying the lifting of the probe, is eliminated due to the fact that the width of its working part in cross section is slightly more than half a diameter of the wire (Fig. 56). Switch 25, connected to probe 24, sends a command to the air distributor: Tel, which bypasses air from one cavity of pneumo-chamber 21 to another, with lever 22, disengages unit 18 from engagement with gear 17 and re-engages it with another gear; the direction of rotation of the lead screw t1 is reversed; the extreme turn of the next row of wire is laid close to the right wall of the coil 4, raising the probe 24 (Fig. 5c); the carriage 9 remains stationary until the nut 13 moves to the left until contact with the tool 14, after which the carriage 9 moves to the left. When the row is filled, the process is repeated in reverse order.

The duration of the carriage 9 stopping at the end of each row, ensuring the timeliness of the wire moving after the extreme turn has been laid and some advance of the laid turn relative to the htc of the sleeve 10, is achieved by adjusting the position of the stops 14 and 15 fixed by the lock nuts 16. When the coil 4 is filled with wire, the drive turns off the wire wrapping is removed and removed from the coil 4, for which the removable wall of the coil is detached.

/ Placement of the test leads

the stacker reversing mechanism close to the coil walls allows carriage reversal as the coil is actually filled across the width with another row of wire, and the possibility of axial movement of the propeller nut relative to the carriage between adjustable stops provides the necessary stop at the end of each turn; all this increases the quality of wire laying and reliability of the device; as a result, the need for constant operator-sided rewinding process is eliminated, the possibility of multi-station service is created, due to which the productivity of work during rewinding of thick welding wire (3 mm or more in diameter) can be doubled. Cros; moreover, the use of the proposed device will increase occupational safety.
