HYDRAULIC SYSTEM FOR WELDING MACHINE BED CONTROL Russian patent published in 2009 - IPC B23K11/25 B23K11/04 F15B15/00 

FIELD: mechanics.

SUBSTANCE: invention relates to hydraulic system of welding machine bed control and can be used in the devices for contact butt-seam welding of strips mounted in the endless rolling mills. The hydraulic system comprises a hydraulic distributor, a flow regulator set on the pressure line of the hydraulic drive with the possibility of connection to the head end of the control hydraulic cylinder which is coupled to one end of the hydraulic distributor by the rod end and to the other end of the hydraulic distributor by a check valve. An additional flow regulator is mounted parallel to the first one. Inlets of both flow regulators are connected to the pressure line through a common hydraulic distributor. Outlets of each flow regulator are connected to the rod end of the control hydraulic cylinder and to the flow control unit through an individual hydraulic distributor.

EFFECT: invention can be used in the devices for the contact butt-seam welding of strips.
