Problems solved by technology

[0003] Most of the existing hot-pressed metal forming hydraulic presses are extruded by four-column hydraulic structure, and the metal is formed by extruding the metal in a vertical manner. Due to the high hardness and high strength of the metal, the power mechanism of the existing hydraulic press cannot meet the requirements, or When the requirements are met, the heat accumulation of the hydraulic oil is more serious

Abstract

The invention relates to a power mechanism for a hydraulic machine. The power mechanism comprises an oil tank body, the oil tank body is of a cuboid structure and is filled with hydraulic oil, a firstoil return pipeline and a second oil return pipeline are arranged on the end face of one side of the oil tank body, one end of the first oil return pipeline and one end of the second oil return pipeline both communicate with the interior of the oil tank body, and the other end of the first oil return pipeline and the other end of the second oil return pipeline communicate into an oil cooler; a first oil outlet pipeline, a second oil outlet pipeline and an oil inlet pipeline are arranged on the end surface of the other side of the oil tank body; one end of the first oil outlet pipeline, one end of the second oil outlet pipeline and one end of the oil inlet pipeline all communicate with the interior of the oil tank body; the other end of the oil inlet pipeline communicates with a liquid filling pump; and the other end of the first oil outlet pipeline and the other end of the second oil outlet pipeline communicate with a hydraulic cylinder. Under the condition that the temperature of thehydraulic oil rises to the same height, the hydraulic cylinder can obtain higher pressure, and then the output power value of the power mechanism can be increased.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a power mechanism for a hydraulic machine. Background technique [0002] A hydraulic press is a machine that uses liquid as a working medium and is made according to Pascal's principle to transfer energy to realize various processes. A hydraulic press generally consists of three parts: the machine (main machine), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. [0003] Most of the existing hot-pressed metal forming hydraulic presses are extruded by four-column hydraulic structure, and the metal is formed by extruding the metal in a vertical manner. Due to the high hardness and high strength of the metal, the power mechanism of the existing hydraulic press cannot meet the requirements, or When the requirements are met, the heat accumulation o...
