Technical Field

[0001] This utility model relates to the field of hydraulic system technology, and in particular to a hydraulic station for a medium-sized hot isostatic press. Background Technology

[0002] A hot isostatic press (HIP) is a process equipment that uses high-pressure gas (usually argon) as the pressure medium to achieve densification and sintering of powder metallurgy, ceramics, or composite materials under high temperature and isotropic pressure. With the rapid development of manufacturing technology and the increasing maturity of casting technology, the application range of HIPs is expanding, covering more and more industries, and they need to quickly adapt to different product processing environments. Depending on the factory environment, the discharge method of the HIP equipment varies, as do the required equipment accessories. For installations in complex working environments, with large frames and insufficient operating space, the movement of the HIP frame, the lifting of the upper plug, and the lower plug descent all require sufficient power. Traditional hydraulic stations with multiple valves installed separately result in complex piping, high leakage risk, and high energy consumption. Utility Model Content

Figure 1 As shown, the system includes an oil tank 1, a power unit 2, and a direction and flow control unit 3. Both the power unit 2 and the direction and flow control unit 3 are mounted on the oil tank 1. The power unit 2 is connected to both the oil tank 1 and the direction and flow control unit 3, and is used to pressurize the hydraulic oil in the oil tank 1 and deliver it to the direction and flow control unit 3. The direction and flow control unit 3 is connected to each actuator of the medium-sized hot isostatic press, and is used to adjust the flow direction and flow rate of the hydraulic oil to control the movement of each actuator of the medium-sized hot isostatic press, thereby achieving precise control of each moving part of the medium-sized hot isostatic press. This embodiment, by uniformly mounting the power unit 2 and the direction and flow control unit 3 on the oil tank 1, forms a modular design. This not only shortens the connecting pipelines between components, reduces hydraulic loss and leakage risks, making the system response faster and control more precise, but also improves the overall structural compactness and saves installation space.

[0028] Preferably, such as Figure 2 As shown, the power unit 2 includes a motor 21 and a hydraulic pump (not shown in the figure). The motor 21 is installed on the outside of the oil tank 1, and the hydraulic pump is installed inside the oil tank 1. The output shaft of the motor 21 is connected to the hydraulic pump. The oil outlet and direction of the hydraulic pump are connected to the oil inlet of the flow control unit 3. The motor 21 drives the hydraulic pump to operate, pressurizes the hydraulic oil in the oil tank 1 and delivers it to the direction and flow control unit 3, thereby realizing precise control of each actuator of the medium-sized hot isostatic press.

[0029] Preferably, the direction and flow control unit 3 includes a valve seat 31, a double one-way throttle valve 32, a first one-way valve 33, and a solenoid directional valve 34.

The double one-way throttle valve 32, the first one-way valve 33, and the solenoid directional valve 34 are all mounted on the valve seat 31, and are connected in series to the oil passage within the valve seat 31. The double one-way throttle valve 32 is used to regulate the flow rate of the hydraulic oil to precisely control the movement speed of each actuator of the medium-sized hot isostatic press. The first one-way valve 33 is used to lock each actuator of the medium-sized hot isostatic press. The position of the mechanism after its action prevents a sudden drop in load; the solenoid directional valve 34 is used to control the flow direction of hydraulic oil and switch the direction of motion of each actuator of the medium-sized hot isostatic press; the double one-way throttle valve 32, the first one-way valve 33 and the solenoid directional valve 34 work together to ensure that each actuator of the medium-sized hot isostatic press operates smoothly and responds quickly, meeting the requirements of the medium-sized hot isostatic press for high-precision and high-stability motion control; in addition, the double one-way throttle valve 32, the first one-way valve 33 and the solenoid directional valve 34 are connected to the valve seat 31 through an internal oil passage, reducing the external pipeline connection, which not only makes the structure more compact and easier to maintain, but also reduces the space occupied, effectively reduces the risk of leakage, and improves the overall reliability and sealing performance.

[0030] Preferably, multiple dual one-way throttle valves 32, first one-way valves 33, and electromagnetic directional valves 34 are provided and arranged in parallel along the longitudinal direction of valve seat 31 to meet the needs of independent control of multiple actuators of medium-sized hot isostatic press.

[0031] Preferably, the direction and flow control unit 3 further includes a second check valve 35, which is installed on the oil inlet of the valve seat 31 to prevent hydraulic oil backflow and ensure pressure stability.

The electromagnetic relief valve 41 is used to regulate the pressure and prevent overload. The accumulator 42 is connected to the oil passage in the valve seat 31 to store hydraulic energy, absorb pressure pulsations, and compensate for leakage, ensuring pressure stability. Through the coordinated work of the electromagnetic relief valve 41 and the accumulator 42, the response speed and pressure control accuracy are improved, meeting the operating requirements of the medium-sized hot isostatic press under high pressure and high stability conditions.

[0033] Preferably, the hydraulic station further includes a filter unit 5, which includes an oil outlet filter 51 and a return oil filter 52. The oil outlet filter 51 is installed on the oil inlet of the valve seat 31 to filter out solid impurities in the hydraulic oil and prevent contaminants from entering and causing component wear or blockage. The return oil filter 52 is set at the return oil port of the oil tank 1 to filter the hydraulic oil returning to the oil tank and ensure the cleanliness of the oil.

[0034] Preferably, the hydraulic station further includes a monitoring unit 6, which includes a pressure gauge 61 and a level gauge 62. The pressure gauge 61 is installed on the valve seat 31 to monitor pressure changes in real time and ensure that the working pressure is within the set range.
