Auxiliary hydraulic set for great tonnage press

Abstract

The auxiliary hydraulic set for great tonnage press consists of floating movable platform attached to the press, platform seat and manipulator suspended over the platform seat. The auxiliary hydraulic set features that the floating movable platform is set on the tracks on the platform seat via four rollers and support springs and has one connected translation hydraulic cylinder to constitute displacing mechanism, the platform seat has one demolding stage hole and the manipulator is operated and controlled with the lifting hydraulic cylinder, pushing hydraulic cylinder and clamping hydraulic cylinder over the hole and the supporting hydraulic cylinder below the hole. The completely hydraulic structure can realize the horizontal displacement of the floating platform and the mechanical displacement and demolding of large pressed member.

Description

technical field [0001] The invention relates to an auxiliary hydraulic device of a large-tonnage press, which belongs to the auxiliary device category of large and medium-sized presses, in particular to an auxiliary hydraulic device for a press with translation, lifting and jacking functions. Background technique [0002] Large-tonnage presses are the main production tools for producing heavy and large components in powder metallurgy production. When working procedures such as the displacement of the mold, not only can only rely on traditional tools such as cranes in the workshop, but also must rely on the heavy physical labor of many operators. Take the cemented carbide composite roll produced by the enterprise where the inventor works as an example: the composite Roller molds are large and heavy. Generally, each set of molds is 200-400Kg, and the weight of a single compact is 50-150Kg. It is impossible to operate manually. [0003] Therefore, how to provide a feasible aux...
