Title:
UPSETTING OIL CYLINDER AND FRICTION WELDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/168960
Kind Code:
A1
Abstract:
An upsetting oil cylinder (100), comprising a first oil cylinder (1), a second oil cylinder (2), and a locking mechanism. A piston rod of the first oil cylinder (1) is configured to be fixedly connected to a movable sliding table; a movable sliding table connecting base (3) is fixedly provided on the movable sliding table; at least part of a piston rod of the second oil cylinder (2) can be located in the movable sliding table connecting base (3)and is slidably connected to the movable sliding table connecting base (3); the movement direction of the piston rod of the first oil cylinder (1) is parallel to the movement direction of the piston rod of the second oil cylinder (2); and the locking mechanism can lock the movable sliding table connecting base (3) to the piston rod of the second oil cylinder (2). Further provided is a friction welding machine, comprising the upsetting oil cylinder (100). The upsetting oil cylinder and the friction welding machine can reduce manufacturing costs.
