    The invention relates to electrical multi-spot resistance welding machine for the production of welded bar gratings produced by welding cross-bars into the narrow side of parallel, upright flat bars. Such a machine has a pressure-beam which is guided vertically on a frame for lowering onto and raising away from the bars to be welded. Two rows of electrodes are disposed on the pressure beam, the rows being transverse to the feed path of the flat bars and the electrodes in the two rows being aligned in the feed direction of the flat bars and the electrodes of each aligned pair thus formed are connected to the secondary terminals of opposite polarity of a respective welding transformer. The electrodes are mounted in the pressure beam such that the electrodes of each pair aligned in the feed direction of the flat bars, are at least partially independently slidable vertically within the beam against a biasing force, the pressure beam and the welding transformers being mounted in a single unit for lowering and raising together. Short flexible supply leads connect the electrodes with the transformers.

    (5) MACHINE FOR MULTI-POINT CONTACT WELDING
    The invention relates to resistance welding in the manufacture of welded grate bars by welding the transverse rods into the side sides of the parallel, one hundred to 5 DX on the edge of flat longitudinal strips.
    A known machine for multi-spot welding, comprising a pressure beam mounted on a frame and connected with a reciprocating movement to create a welding force, along which two isolated electrode rows of 15 holders with electrodes, each of which spring-loaded to the beam and connected to the second winding of the welding transformer. Mator using busbars and flexible then to the VO to l .20
    However, in the manufacture of grates, transverse rods must be welded to the sides of the strips throughout their entire thickness, while the welding depth in known welding machines is 25
    The grids are always small and only part of the diameter of the thin rods. From this it follows that both the amount of pressure of the pressure beam, and the welding pressure and electrical power required for welding, in welding machines for the manufacture of grates should be significantly greater than in the known machines for welding grids.
    The large amount of pressure beam supply requires correspondingly large radii of cranks or eccentrics, which provide the usual movement, and, together with high pressure, the need for a very powerful motor that creates a large torque.
    In addition, high welding power is required, which determines the choice of certain parameters of the conduits between the secondary winding of welding transformers and welding electrodes, which (conductors) should be as short as possible and
    393
    at the same time, flexible if the work is done with electrodes that are moved relative to the welding transformers. In two-point welding with stationary electrodes and moving shunts, the requirement for flexible and relatively long conductors and electrodes is removed, which primarily favors the use of moving passive shunts, especially since they can be easily known in a known manner so as to ensure uniform pressure distribution of the pressure beam on both welding points.
    The purpose of the invention is to reduce drive power.
    This goal is achieved by the fact that, in a multipoint contact welding machine, containing a pressure bar mounted on the frame and coupled with a reciprocating drive to create a welding force, along which two isolated from each other rows of electrode holders with electrodes are installed, each of which spring-loaded to the beam and connected to the secondary winding of the welding transformer using busbars and flexible current leads, welding transformers with busbars mounted on the pushbutton In this case, the same number of transformers is mounted on both sides of the pressure beam. The pressure beam is provided with a clamp installed along the beam in relation to it in the direction of its movement, located along the beam, spring-loaded and interacting with the electrode holders. In addition, the electrode holders of each row are combined into three nodes isolated from each other.
    1 shows a machine with a side wall removed and a cut through a pressure beam, side view; 2 shows the lower part of the pressure beam on an enlarged scale, the section in FIG. 3 is the clamp and the electrode holder; figure 4 - chart of the pressure depending on the angle of rotation of the crank.
    The pressure beam 1 is installed on the base 2 of the welding machine with the help of two single-arm levers 3. and on each side. Both levers 3 and A are installed with the possibility of rotation both on the bed 2 of the machine and on
    934
    push beam 1 and form a parallelogram mechanism, since the distance between the hinges of both levers is the same and the levers are parallel
    5 each other.
    The one-arm lever k is extended beyond the hinge point with beam 1 and at its end connected to the rocker 5. The other end of the rocker arm 5 is rotatably connected with the wide end 6 of the connecting rod 7 and rigidly connected with the worm gear 8. At the wide end of the connecting rod 7 The worm to 9 is pivoted, but without the possibility of movement, which engages with the worm wheel 8.
    In an idle machine, it is possible by rotating the screw 9 by means of a motor or by manually turning the rocker arm 5 around its mounting point at the wide end of the crank 7. This allows the pressure bar 1 and all related parts to be raised to a height than in the working condition of the machine so that, for example, it is possible to replace the electrodes or repair it. Through the other end of the connecting rod 7, the eccentric 10 is passed, which is rigidly mounted on the shaft 11, driven by the motor. Due to this, the rotation of the shaft 11 is converted into a reciprocating rhythmic movement in the vertical plane of the pressure beam and associated parts.
    On either side of the pressure beam 1, rigidly connected transformers 12 and 13 are mounted, the secondary windings of which feed the busbars lA-17 connected by short and flexible conductors 18-21 to rigid conductor arms 22-25 that are electrically connected with electrode holders 26 and 27- Electrodes 28 and 29 form a pairwise two-point welding area. The corresponding passive shunt can be formed by a metal stand. For standing on the edge of iron ribbons or by the iron ribbons themselves.
    ° Inside the hollow pressure bar 1, the presser 30 slides. It rests on the pressure beam and is spring-loaded with coil springs 31, the voltage of which is adjusted by means of adjusting
