MACHINE FOR MULTI-POINT CONTACT WELDING REINFORCING GRIDS Russian patent published in 1995 - IPC

FIELD: welding. SUBSTANCE: machine has rectangular bed, unit for laying longitudinal reinforcing rods, a carriage with feed mechanism for the longitudinal rods, welding transformers, and units of current inlet electrodes connected to the transformers, bypass electrodes, carriage for moving reinforcing grid, and clamping mechanism for longitudinal rods. Structural elements of the unit for laying longitudinal rods, units of current inlet electrodes, and clamping mechanism intended for interaction with longitudinal rods are made adjustable in the direction being perpendicular to the bed plane. When the units are adjusted so to be in one plane, they ensure welding and grid motion without forces and moments, which would deform the grid. EFFECT: increased quality in grid manufacturing. 5 cl, 4 dwg
