    Apparatus for the planetary feeding of electrode wire having means for adjusting the pushing force exerted on the electrode wire by electromagnetic means. Opposed canted rolls are mounted for rotation about their axes upon a first housing part which is rotatable about the axis of an elongated electrode wire which passes between and is fed by the canted rolls. A second housing part, which is disposed coaxially of the first housing part, bears means such as a cam or a cone which interacts with roll adjusting means mounted on the first housing part so as to adjust the force with which the canted rolls engage the electrode wire in accordance with relative motion between the two housing parts. The second housing part is driven for rotation about its axis. The degree of motion of the two housing parts relative to each other, thereby to vary the force with which the canted rolls engage the electrode wire, is determined by an externally controlled electromagnetic means which can be adjusted while the welding apparatus is in continuous operation.

    The proposed device (Figs. 1, 2, 3, 9, 11 and 13) contains an electric motor 1, on the hollow shaft 2 of which a housing 3 is fixed. In the housing 3 there are pistons 4, on which rollers 5 are rotatably mounted on axes for supplying wires 6, the axes of which constitute an angle. Each of the pistons 4 has a blind hole in which the spring 7 is placed, with one end in contact with the core with a gap relative to valve 3, and the other end (in the piston) tends to push the piston out of the blind hole.
    On the undercuts of the peripheral part of the housing 3 in the plane of the pistons 4 and the electrode wire 6 are pivotally attached to the axis x8 two shoulders levers 9. One end of each double shoulders lever 9 rests on the end portion of the corresponding piston, while its other end contacts with the roller 10 or cutting ball; in fig. 3 - the same, with adjustable JQ 1 with a working surface of 12 or 13 by pushing the buoyancy force through 14 or cam 15.

    In one case, the levers 9 are in contact with a cam, made in the form of axial50
    in the radial or axial direction under the action of an electromagnetic field using a dynamic element connected to the housing.
    FIG. I presents the case when the cone 14 is placed in the sleeve 19, which is a dynamic element, with the help of the bearing 20. The radially wound coil 21, rigidly fastened to the motor body 1, creates an axial magnetic field 22.

    these rollers 5 occur as a result of the relative movement of the rear end of the levers 9 in a direction perpendicular to the axis 8.
    In another case (Fig. 4), the pistons 4 are pressed directly through a copier made in the form of a cone-shaped body 16, which moves with the possibility of rotation along the cutting 17 in the body 3 and its inner cone-shaped surface 12 presses on the pistons 4. In In this case, the outer ends of the pistons 4 are also conical. To reduce frictional resistance when sliding
    rotary bearings are used in the outer ends of the pistons
    Until now, the kinematic scheme of a spon-moving cone 14, and in another case, in the form of a radially rotating
    Pressing the electrode wire was carried out using rollers 5 for feeding the wires, which are mounted on pistons 4.
    In one case, the levers 9 are in contact with a cam, made in the form of axial
    in the radial or axial direction under the action of an electromagnetic field using a dynamic element connected to the housing.
    FIG. I presents the case when the cone 14 is placed in the sleeve 19, which is a dynamic element, with the help of the bearing 20. The radially wound coil 21, rigidly fastened to the motor body 1, creates an axial magnetic field 22.
    The principle of operation of the device is as follows.
    The magnetic field 22 excited by the coil 21 moves the dynamic element - the sleeve 19 - in the axial direction relative to the housing 3, and this sleeve 19 in turn translates a cone 14 with a tapered surface 12. Levers 9 are in contact with this tapered surface rotating around the axis 8, the pistons 4 and the rollers 5 connected to them are pressed or released, respectively, to the direction of the magnetic field, to the electrode wire 6.
    In the case depicted in FIG. 2, the copier (cone 14) is secured by cutting 17 in housing 3. The coil 23 with radial winding, iron core 24 and grooves 25 is rigidly attached to the engine housing 1, while surrounding the outer cylindrical surface of the cone 14, which performs the function dynamic element.
    In this case, the principle of the device is as follows.
    When current is applied to the coil 23, an iron core 24 is excited in the air gap 26 and in the body of the cone 14 a vortex magnetic field (sliding magnetic field) 27 that resists the rotation of the cone 14 rotating from the axis of the engine 1 together with the body 3. As a result the cone 14 rotates in the cutting 17 relative to the housing 3 and thus moves in the axial direction, and it lifts the levers 9 at one end. These levers press in turn on the pistons 4, resulting in rollers 5 for feeding the wire are pressed to electrode wire 6.
    In this case, the device can be made in two versions, namely, using an electromagnetic field, excited by the internal stator (Fig. 5) or the external stator (Fig. 5).
    The principle of operation of the device with an internal stator shown in FIG. 3, is similar to the principle of operation of the device with an external stator (Fig. 2).
    The arrangement of coils located inside or outside the dynamic element is depicted in FIG. 5 and 6. An iron core coil 28 and 24 is shaped like a star with several sector poles 29 (Figs. 5 and 6), in which there are additional notches 25. A coil 23 is wound on this core.
    The device for the planetary supply of electrode wire can be made to adjust the buoyancy with the tangential magnetic field W. In this case, the stator device is as follows: the stator (Fig. 8) is mounted outside of the dynamic element 30 or the cone 14 and the stator (Fig. 7) placed inside.

    Axially arranged winding 31 excites a tangential electromagnetic field. A stator with an iron core 28 is provided with the same winding. A case of using an electromagnetic field to drive a cam is shown in FIG. 9-13. The cam 15 (FIGS. 9 and 10) has a sector undercut with a working surface 13 in a cylindrical disk, which is an integral part of a cylindrical body, which performs the function of a dynamic element 30. This cylindrical body - a dynamic element 30 - is mounted using a sub-holder 20 on the housing 3. In the inner zone of the dynamic element 30 is located a concentric coil 23, which (according to the type of winding) excites a vortex magnetic field 27 or a tangential magnetic field W. With the help of sector undercuts with a working angle Nosta
    0 13 the cam 15 contacts the levers 9 through the balls 11.
    The principle of operation of the described device is as follows (Fig. 9).
    The housing 3 rigidly mounted on the shaft of the engine 1 is rotated by the torque of the engine. Dynamic element 30 with cam 15 rotates due to contact of rollers 10 in sector undercuts with working surface 13 of cams 15, and they are installed in bearing 20. When coil 23 excites a vortex magnetic field 27 or tangential electromagnetic field W, it closes through a dynamic element 30, creating an inhibitory effect. This leads to a relative rotation of the dynamic element 30 and, respectively, of the cam 15 relative to the housing 3 and, consequently, to the lifting of the levers 9 along the sector notches with the working surface 13 of the cams 15. As a result, the levers 9 press their rear ends at
    0, pressure is transmitted through rollers 5 to the electrode wire.
    The adjustment can also be carried out if the levers 9 are positioned perpendicular to the feed direction (Figs. 11 and 12) by pressing the rollers with the cams through a vortex magnetic field 27 or the tangential electromagnetic field W. In this embodiment, the cam 15 is performed inside the cylindrical body 30 (FIG. 12), this cam being part of this
    Q cylindrical body 30.
    The principle of operation of the device in the regulation is similar to the previous case. The coil 23 excites an electromagnetic field 27 (W), which is closed by an iron core 28 and acts as a rotating magnetic field 27 or a tangential electromagnetic field W causing relative rotational motion of the dynamic element 30 relative to the cam0
    15 and the cam 15 relative to the housing 3. This movement of the housing 3 and the cam 15 leads to the movement of the levers 9, which at one end contact through the rollers 10 with the working surface 13 of the cam 15, and at their shorter end - with the piston 4, resulting in the wire feed rollers 5 are pressed against the electrode wire 6.
    In addition, the device can be controlled with the use of the electromagnetic field IF of the motor rotor itself (Fig. 13). In this embodiment, the shaft 2 of the electric motor 1 is rigidly connected to the elongated part of the housing 3. Around the elongated part of the housing 3, the cam 15 can freely rotate by means of a bearing 20, with the working surface 13 of which are in contact with the arches 11, which are attached to the long arms of the two shoulders 9 One end of the cam 15 with the end part 32 performs the function of a dynamic element, and this end part 32 has a minimum gap relative to the rotor winding 33, which is separated from the end part 32 by recesses 34. The motor and device are closed A common cover 35, which is fastened with bearings 36 on the motor shaft. Two motors are made on the front of the shaft 2

    opposite sector undercuts, the diameter of which corresponds to the diameter of the rollers 5 for feeding the wire 6.
    The principle of operation of the described device is as follows.
    When an electric current is applied to the rotor of the electric motor 1, a vortex magnetic field 37 is excited around the winding, the power lines of which are closed through the end part 32 of the cam 15, which performs the function of a dynamic element. This electromagnetic field 37 resists the rotation of the cam 15, which, when rotated around the housing 3, has a relative delay, as a result of which it acts on the levers 9, which in turn affect the rollers 5.
    The proposed device has the following advantages: creating the possibility of automatic regulation depending on the wire diameter and buoyancy force, without opening the installation; making it possible to precisely adjust, depending on the buoyancy, both before the start of welding and during the welding process; creating precise control of the buoyancy depending on the material supplied (steel, aluminum or tubular electrode wire) both before the start of welding and during the welding process.
