Cooling system of thermal forming hydraulic machine

Abstract

The invention belongs to the technical field of thermal forming hydraulic machines, and particularly relates to a cooling system of a thermal forming hydraulic machine. The cooling system of the thermal forming hydraulic machine comprises a water chilling unit, a gate valve A, a gate valve B, a Y-shaped filter, a gate valve C, an electromagnetic water valve, a cooler, a gate valve D, a lower platform cold water plate, a flow temperature sensor A, a gate valve E, an upper platform cold water plate, a flow temperature sensor B, a gate valve F and a gate valve G; and the cooling system of the thermal forming hydraulic machine further comprises a controller which controls the working state of the cooling system and is internally embedded with a linear feedback system, the signal output ends ofthe flow temperature sensor A and the flow temperature sensor B are connected with the input end of the controller, and the output end of the controller is connected with the water chilling unit andthe electromagnetic water valve. The cooling system of the thermal forming hydraulic machine can cool an upper heating platform and a lower heating platform simultaneously, and is high in cooling efficiency, compact in overall layout, simple in structure, stable in cooling effect and capable of achieving cyclic utilization of a cooling water source.

Description

technical field [0001] The invention belongs to the technical field of thermoforming hydraulic presses, in particular to a cooling system for thermoforming hydraulic presses. Background technique [0002] Existing techniques and drawbacks: [0003] The thermoforming hydraulic press is a typical high-end equipment, suitable for the aerospace field, mainly used for the forming technology of titanium alloy parts, and meeting the production mode of small batches and multiple varieties in this field. For many years, this type of press was mainly monopolized by some foreign equipment manufacturers. In recent years, with the progress of my country's industry and the development of high-end equipment, my country's high-end equipment manufacturers have started to develop thermoforming hydraulic presses and have achieved success. However, the thermoforming hydraulic press belongs to high-temperature equipment. During the production process of the thermoforming hydraulic press, due t...

Problems solved by technology

However, thermoforming hydraulic presses are high-temperature equipment. In the process of producing parts, the cooling system of thermoforming hydraulic presses is complicated, the performance is unreliable, and the cooling water source flow and pressure supply provided by the workshop are unstable. High temperature overflow often occurs, causing the whole The high temperature heat conduction phenomenon of the machine causes the equipment to stop and cool down, which affects the production efficiency and quality of thermoforming hydraulic machine parts
