Problems solved by technology
Due to the influence of the self-weight of the tool holder, a partial load force will be generated during the extension and retraction of the servo hydraulic cylinder, which will cause partial friction between the piston rod and the guide sleeve, the piston and the cylinder, and long-term operation will cause the servo hydraulic cylinder to Scratches on the inner wall of the cylinder cause internal leakage, which affects the output characteristics and service life of the servo cylinder

The invention relates to the technical field of hydraulic-roll-cutting-type metal plate shearing machines, in particular to an eccentric-load preventing hydraulic system of a hydraulic-roll-cutting-type metal plate shearing machine. The eccentric-load preventing hydraulic system comprises a first servo hydraulic cylinder loop, a second servo hydraulic cylinder loop and an eccentric-load preventingloop which are hinged to a rack and an upper tool rest correspondingly. In the rolling shearing process, the first servo hydraulic cylinder loop and the second servo hydraulic cylinder loop are usedfor ensuring the position precision of the tool rest and meanwhile conducting pressure precise control and timely adjustment on rodless cavities of servo hydraulic cylinders; and the eccentric-load preventing loop is used for balancing the weight of the upper tool rest, so that the eccentric-load force borne by a piston rod is reduced, the service life of the servo hydraulic cylinders is prolonged, meanwhile, sudden falling of the upper tool rest due to leakage of the servo hydraulic cylinder hydraulic system or pipeline breakage can be prevented, the tool rest is effectively protected againstdamage, and personal safety is effectively protected. The eccentric-load preventing hydraulic system has the beneficial effects that the rolling shearing process is extremely stable by using the eccentric-load preventing loop, and the characteristics of simple structure, high practicability and easy implementing are achieved.
Description
technical field [0001] The invention belongs to the technical field of hydraulic rolling-cutting type metal plate shearing machine, and in particular relates to a hydraulic system of anti-eccentric load hydraulic rolling-cutting type metal plate shearing machine. Background technique [0002] The hydraulic roll-cut metal plate shearing machine is a large-scale steel plate shearing equipment that cuts steel plates in sections and is one of the core equipment for modern medium and heavy plate production. Based on the rolling shearing principle, the hydraulic rolling shearing type metal plate shearing machine adopts the servo hydraulic cylinder direct drive compound connecting rod shearing mechanism to realize the horizontal rolling shearing of the steel plate with the arc-shaped upper cutting edge. The servo hydraulic cylinder and the frame adopt the form of horizontal hinged installation. In the process of rolling and shearing, the servo hydraulic cylinder swings slightly. D...
