[CN 201821701821.8] transmission structure of press forging machine


[CN 201821701821.8] A Forging Machine Transmission Structure Title: A Forging Machine Transmission Structure Application Number: CN 201821701821.8 Applicant: Anhui Zhongzhi Rail Transit Equipment Manufacturing Co., Ltd. Application Date: 2018-10-19 Patent Type: Utility Model The utility model discloses a forging machine transmission structure, including an oil tank, a control panel, a hydraulic pump, a first pipe, a second pipe, a sealed heat conduction plate, a heating resistor, a heat dissipation fin and a heat dissipation hole, A control panel is installed on one side of the oil tank; when the utility model supplies oil through the hydraulic pump, the overflow valve cooperates with the throttle valve to adjust and balance the flow in the hydraulic system, and opens when the load exceeds the specified limit. At the same time, the temperature of the hydraulic oil rises due to extrusion after working in the hydraulic cylinder. When the oil return pipe falls into the oil tank, due to several cooling fins with cooling holes set on the oil return pipe, the contact area with the air is increased, which can speed up the heat dissipation effect of the hydraulic oil. At the same time, when the temperature is low, the heat generated by the heating resistor at the bottom of the oil tank is conducted to heat the hydraulic oil through the sealed heat conduction plate to keep the hydraulic oil temperature at a normal level. Ensure the normal operation of the equipment.
