Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to an electrical cabinet used in a hydraulic press with a heat dissipation structure. Background Art

[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. Hydraulic presses require electrical cabinets for control when in use.

[0003] Most of the electrical cabinets used in existing hydraulic presses do not have a heat dissipation effect. When the hydraulic press works for a long time, the temperature of the hydraulic oil continues to rise, which will reduce the reliability of the hydraulic press operation.

[0006] To this end, we proposed an electrical cabinet for a hydraulic press with a heat dissipation structure to solve the above problems. Utility Model Content
