A double-column free forging hydraulic unit

Abstract

The invention provides a double-column free forging hydraulic unit, which includes a frame, a mobile workbench, a movable beam, a main working cylinder, a return cylinder, a hydraulic system, an electrical system, and an operation and control system. The frame includes an upper beam, a lower beam and There are two columns, and the front and rear sides of the lower crossbeam are respectively provided with two raised mounting seats for placing the return cylinder, the outer side of the column is provided with a column sleeve inlaid with a wear-resistant guide plate, and there is also a column sleeve on the frame for installation. The X-shaped guide device of the mobile workbench, the operation and control system includes manual control system, semi-automatic control system, automatic control system and linkage control system. The automatic control system can be switched to the manual control system at any time through the manual operation handle during the working process. It can realize multiple modes of control and conveniently realize the conversion between the above working modes, and can perform manual intervention under automatic mode, and can also solve the problem of troublesome disassembly and assembly of the mobile workbench and poor rigidity of the column, with good safety and high work efficiency high.

Description
