Abstract
949,150. Welding by pressure. BROWN, BOVERI & CO. Ltd. July 17, 1962, No. 27398/62. Heading B3R. An electric resistance spot welding machine for spot welding at various levels comprises a stand 1, a support member mounted on the stand for horizontal movement relative thereto and two co-operating electrodes 7, 7, each electrode having an actuating unit fixed to an arm of the support member and comprising a first piston and cylinder for adjusting the electrode in the vertical direction and a further piston and cylinder co-operating with the first piston and cylinder to produce the welding pressure. The support comprises a pair of spaced arms 2 joined by pieces 3 and horizontally movable in the stand 1, each arm carrying a unit 4 which comprises a cylinder 5 carrying an electrode 7 and guided by rollers 8 in the unit to move relatively to a piston 6 connected to the piston 10 of a main cylinder 9. Each cylinder 5 carries a cam 15 for engaging a limit switch 11 adjustable by a motor-driven spindle 12. A welding transformer or rectifier is carried between the arms 2. In operation the switches 11 are set by push-button control to the required adjusted position of the electrodes as indicated on a scale, oil is supplied to the cylinders 5 through valves 30, 31 to move the cylinders 5 relative to the pistons 6 until the cams 15 actuate the switches 11 which causes electrically controlled valves 32 to close. The electrodes remain in their adjusted positions spaced from the work until cylinder 9 is supplied with pneumatic or hydraulic fluid to force the pistons 6 down and hence the electrodes into contact with the work and a spot weld is effected. After welding the angle 21, the electrodes are returned, the support 2 is moved horizontally, the limit switches are set to new positions and welding of angle 22 is effected. The workpiece may travel along a rail track. Displacement of the arms 2 and of the electrodes can be achieved by programmed control.
