    • 专利摘要:
    A multi-module system for advancing an electrode wire from a supply location to a field welding station via a plurality of spaced conduit sections is described. Each conduit section is succeeded and preceeded by a plurality of wire-advancing heads, with the front-most head adjacent the welding station being driven at constant speed and the remaining heads being driven at a variable tension. The tension in the variable-tension heads is initially set to advance the wire through the conduit sections in a continuous serpentine-like path. When the tension in the wire downstream of the forward-most head increases to impart a "straightening" component to the advancing wire, the forward-most head generates a control signal which is fed back via a regulator on the rear-most head to successively vary the tension in the successive rear heads in a successively decreasing manner corresponding to the decrease in total resistance of the wire tension seen by such successive heads. Such distribution of correcting force applied to the successive heads results in a rapid and effective restoration of the serpentine-like wire path through the system.

    (54) DEVICE FOR ELECTRODE WIRE SUPPLY
    drives and feed drives that are closest to the current drive; in fig. 5 is the same when the signal for interaction is received from all feed drives and the serpentine motion of the electrode wire is restored; in fig. 6 is a schematic diagram of the electrical connections between all the drives of the device; in fig. 7 is a longitudinal section of the feed drive; in fig. 8 is an AA section of FIG. 7; in fig. 9 is a longitudinal section of the drive unit embedded in the handle of the welding apparatus.
    The device for supplying the electrode wire has four actuators 1, 2, 3, 4 interconnected by elastic hollow sleeves 5, 6, 7. The first actuator 1, which is built into the handle of the device, the so-called pull drive, acts as a master drive .
    The last actuator 4, which is closest to the coil 8 with electrode wire 9, the so-called pushing actuator 4, is connected to one end of the hollow hose 7. Between the actuator 1 and the actuator 4 two equal intermediate actuators 2 are located at equal distances from the other and 3, with the intermediate drive 2 connected to the ends of the hoses 5 and 6, and the other intermediate drive 3 to the other end of the hose 6 and the hose 7.
    Each of these drives has its own speed controller, which is built into the common block 10. The first drive 1 has a speed controller 11, the first feed drive 2 is the controller 12, the second feed drive-3 is the controller 13 and the third feed drive 4 - regulator 14. All regulators have different depth of feedback.
    The unit 10 can be installed to the feed drive 4 or to the current source supplying the device, due to which the need for other drives to carry controllers is no longer necessary.
    The electrical connection between the actuators 1-4 and their corresponding regulators 11-14 is carried out by means of the electric wires 15-18, and the connection between the regulators-conductors 19 themselves.
    For the implementation of feedback between the tapping drive 1 and the other drives, a current supply cable of the hose 5 and the conductor 20, the cable of the hose 6 with the conductor 21 and the cable of the hose 7 with the conductor 22 are used. These conductors 20-22 are connected to the Exhaust drive regulator one.
    Each drive of the welding device has an electric motor 23 and a planetary head 24 of a known type, mounted in the drive housing. The latter consists of two parts - the front .25 and rear 26, interconnected by means of an internal coupling 27 with a thread
    Since the body of each drive serves as a conductor for welding current, i.e., it is current-carrying ,. the electric motor 23 is insulated from it by insulating sleeves 5 of a cann 28 and washers 29. It is attached to the drive housing with screws 30, which pass through the insulating sleeves 31 and press motor 23 to the inner sleeve 27 from the front.
    10 Coupling of the hoses 5, 6 and 7 to the drives is carried out by means of connecting sleeves 32, to which are attached tubes 33 for supplying protective gas, which serves simultaneously for cooling
    5 electric motors. The shielding gas passes through the gap 34 and the holes 35 made in the rear insulating shroud 29. Each drive is insulated from the outside with a plastic lining 36.
    0 T The drive is structurally different from the others only in that one of the couplings has an external thread on which burner 37 is screwed. A switch is also provided for it.
    5 .38 for commissioning and potentiometer 39, which regulates the feed rate of the electrode wire 9.
    The device for supplying the electrode strip works as follows.
    0 In order to fill the device with electrode wire as well as adjust the planetary head 24 in accordance with the body diameter, it is necessary to unscrew the front part 25 of the drive housing
    5 from clutch 27, which allows free access to the corresponding planetary head. After the electrode wire is passed through all the drives, the device is ready for operation.
    0 After switching on the device to control the feed rate by means of a potentiometer 39, the electrode wire 9, which does not pull the drive I and other drives, begins to flow to
    5 place of welding. If, during its movement in the hoses, there are no conditions for additional mechanical resistance, for example, bending of the hose or the wire itself, the pulling drive 1 will not be loaded
    0 and its speed (its engine speed) will be equal to or slightly higher than the speed
    other drives. In this case, the electrode wire begins to be pulled out in the hoses, which immediately loads the pulling drive. In this state, if any disturbing effect on the body movement (for example, bending), which causes additional mechanical resistance, and, consequently, the load on the means moving it, is pushed, the first pulling drive 1 receives an additional, heavy load. At the same time, its motor, in order not to reduce its speed, begins to consume more current. In this case, its speed controller
    i 1 sends a signal through the controllers of the remaining drives to increase the speed of the electric motors.
    Since the feedback between all the drives and their controllers is carried out through the current supply cable of the hoses 5, 6 and 7, all the controllers will have different feedback depths. Consequently, the feedback force between the controller 11 t of the driving drive 1 and the other regulators 12, 13 and 14 will be different and the controller 14 of the most distant drive, in this case drive 4, receives the interaction signal first.
    As a result of the received signal, the regulator 14, which is essentially a current regulator, increases the speed of the electric motors of the drive 4. The latter begins to push the electrode wire faster and the wire acquires a serpentine movement in the hose 7 between the drive 3 and 4.
    The next time the interaction signal is received from the controller 12 of the intermediate actuator 3. The latter adjusts, similarly to the pushing actuator 4, and the serpentine movement of the electrode wire is restored in the hose 6. The other intermediate actuator reacts in the same way, resulting in a serpentine movement of the electrode wire in all the sleeves, i.e., ejection speed of intermediate drives 2, 3 and
    drive 4 becomes faster than pulling drive speed 1. The drive is unloaded and, slowing down the speed of all other drives, pulls electrode wire through all hoses, which continues until other additional resistances occur.
    Thus, due to the direct and reverse effects of some drives on others, the feeding process is restored in the required mode, i.e., the stability of the wire feeding and, consequently, the welding process is improved.
