Description

Technical Field

[0001] This invention relates to the field of hydraulic device technology, and in particular to a hydraulic device with overload protection hydraulic oil. Background Technology

[0002] In modern industrial production and machinery operation, hydraulic systems are widely used in various fields, such as engineering machinery, metallurgical equipment, aerospace, and automobile manufacturing, due to their significant advantages such as high efficiency, stability, and ease of control. Hydraulic systems use hydraulic oil as the working medium to convert hydraulic energy into mechanical energy, realizing the transmission and control of force, thereby completing various complex actions and tasks. With the continuous advancement of industrial technology and the increasing complexity of machinery, higher demands are placed on the performance and reliability of hydraulic systems. Among these, overload protection is one of the key factors for the safe operation of hydraulic systems.

[0003] Application number CN202121617419.3 discloses a hydraulic device with overload protection hydraulic oil, comprising a main body, with a transmission mechanism disposed at the bottom of the main body; the transmission mechanism includes: a piston rod disposed at the middle of the inner wall of the main body; a first piston plate disposed on one side of the outer wall of the piston rod; and a second piston plate disposed at the bottom of the lower end of the piston rod. In this hydraulic device with overload protection hydraulic oil, when hydraulic oil continuously flows into the lower end of the second piston plate, it will push the second piston plate upwards. When the second piston plate reaches its compression limit, the piston cannot move. As the amount of hydraulic oil increases, the pressure in the inner cavity increases. When the pressure exceeds the elastic force of the arc spring, it will push open the movable disc on the drain hole, allowing some hydraulic oil to flow to the upper end of the second piston plate, thereby relieving pressure and preventing the composition of the hydraulic oil from changing at high temperatures and reducing the quality of the hydraulic oil.

[0004] Based on the above patent searches and understanding of the application of existing overload protection hydraulic oil devices: 1. During the operation of a hydraulic press, when the system pressure reaches a certain value and an overload occurs, there is a large compressive force inside the hydraulic press, which may cause the hydraulic oil temperature to rise. Traditional hydraulic devices are difficult to effectively protect against this overload, which can easily damage the internal components of the hydraulic press and shorten its service life. 2. Traditional devices lack effective cooling and monitoring measures to address the potential high temperature issues that may occur during the transfer and temporary storage of hydraulic oil. This makes it difficult to ensure that the hydraulic oil temperature remains within a controllable range, thus affecting the normal and stable operation of the hydraulic press.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a hydraulic device with overload protection hydraulic oil, in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a hydraulic device with overload protection hydraulic oil. This solves the problems of existing hydraulic devices failing to effectively protect against overload conditions, easily damaging internal components of the hydraulic press, shortening its service life, and lacking effective cooling monitoring measures, making it difficult to ensure that the hydraulic oil temperature is within a controllable range, thus affecting the normal and stable operation of the hydraulic press.

[0007] This invention provides a hydraulic device with overload protection hydraulic oil, specifically comprising: a device base; a device frame is respectively provided on the left and right sides of the top of the device base, the middle position of the two device frames is fixedly connected to the left and right ends of the mounting platform, a hydraulic press is installed in the middle position of the mounting platform, an injection component is fixedly installed at the top middle position of the hydraulic press, a flow meter is provided at the top position of the injection component, a magnetic valve is provided at the right side position of the injection component, the left side of the inside of the magnetic valve is tapered, a controller is provided at the bottom position of the magnetic valve, a tripod is provided at the middle position of the inside of the magnetic valve, a telescopic rod is fixedly installed on the left side of the tripod, a magnetic plug is fixedly installed on the left side of the telescopic rod, the tapered position of the left side of the magnetic plug fits the tapered position of the left side of the inside of the magnetic valve, an annular groove is opened in the middle of the tapered circumference of the magnetic plug, and a sealing rubber ring is sleeved in the annular groove of the magnetic plug. A spring is sleeved on the outer side of the telescopic rod, the left side of the spring fits the magnetic plug, and the right side of the spring fits the left side of the tripod.

[0008] Furthermore, a circulation seat is fixedly installed at the front end of the equipment rack on the right side, a containment tank is fixedly installed at the bottom of the circulation seat, and a temperature monitoring device is fixedly installed at the top left side of the circulation seat. The temperature monitoring device is connected to the containment tank through a pipe.

[0009] Furthermore, the temperature control monitor has two interfaces on its left side, and the left front interface of the temperature control monitor is connected to one end of pipeline A, while the other end of pipeline A is connected to the right side of the magnetic valve.

[0010] Furthermore, the left rear end interface of the temperature control monitor is connected to one end of pipeline B, and the other end of pipeline B is connected to the lower right side of the hydraulic press.

[0011] Furthermore, a cooling plate is fixedly installed at the top center of the temperature control monitor, and a fan is fixedly installed at the front end of the cooling plate. The fan is connected to the temperature control monitor via a wiring harness.

[0012] Furthermore, a temperature controller is installed on the upper right side of the temperature monitoring device, and the temperature controller is located on the right side of the cooling plate.

[0013] Furthermore, an operating platform is fixedly installed at the top center of the device base, the operating platform is located directly below the hydraulic press, a pressure plate is provided at the bottom of the hydraulic press, and the pressure plate of the hydraulic press is located directly above the operating platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the hydraulic press is overloaded and the system pressure is too high, the controller and the solenoid valve can work together to disconnect the electromagnetic connection between the solenoid valve and the solenoid plug in time. This allows the solenoid plug to move under the pressure of the hydraulic oil, transferring the hydraulic oil inside the hydraulic press to a storage tank for temporary storage. This effectively relieves the internal pressure of the hydraulic press, prevents damage to the hydraulic press due to overload, and greatly extends the service life of the hydraulic press.

[0015] 2. The temperature controller can monitor the hydraulic oil temperature in real time. When the hydraulic oil temperature is too high, it can automatically start the fan and cool the hydraulic oil through the cooling fins. At the same time, the operator can monitor the hydraulic oil temperature in real time through the temperature controller to ensure that the hydraulic oil temperature is within a controllable range, thus ensuring the stability and reliability of the hydraulic press operation.

[0016] 3. A sealing ring is provided at the contact position between the magnetic plug and the magnetic valve. When the magnetic plug and the magnetic valve are in contact, the sealing ring can seal the gap between them, effectively preventing hydraulic oil in the hydraulic press from leaking into the magnetic valve, reducing hydraulic oil waste, protecting the working environment, and ensuring the normal working pressure of the hydraulic system.

[0017] 4. During the resetting and retraction process of the hydraulic press, the receiving tank can feed the hydraulic oil back to the hydraulic press through the temperature controller and pipeline. The temperature controller can monitor the temperature of the hydraulic oil and, together with the fan and cooling fins, dissipate heat from the hydraulic oil to ensure that the temperature of the hydraulic oil after return is suitable, which is conducive to the normal operation of the hydraulic press again.

Example

[0023] As attached Figure 1 To be continued Figure 6 As shown: This invention provides a hydraulic device with overload protection hydraulic oil, comprising: a device base 1; a device frame 101 is respectively arranged on the left and right sides of the top of the device base 1, the middle position of the two device frames 101 is fixedly connected to the left and right ends of the mounting platform 102, a hydraulic press 2 is mounted in the middle position of the mounting platform 102, an injection component 201 is fixedly mounted in the middle position of the top of the hydraulic press 2, a flow meter 202 is arranged on the top position of the injection component 201, a magnetic valve 203 is arranged on the right side of the injection component 201, the left side of the inside of the magnetic valve 203 is tapered, and a controller 204 is arranged at the bottom position of the magnetic valve 203. A tripod 205 is installed in the middle of the interior of the magnetic valve 203. A telescopic rod 206 is fixedly installed on the left side of the tripod 205. A magnetic plug 207 is fixedly installed on the left side of the telescopic rod 206. The left conical position of the magnetic plug 207 fits into the conical position on the left side of the interior of the magnetic valve 203. An annular groove is opened in the middle of the conical circumference of the magnetic plug 207, and a sealing rubber ring 208 is sleeved in the annular groove of the magnetic plug 207. A spring 209 is sleeved on the outer side of the telescopic rod 206. The left side of the spring 209 fits into the magnetic plug 207, and the right side of the spring 209 fits into the left side of the tripod 205.

[0024] Among them, a circulation seat 3 is fixedly installed at the front end of the equipment rack 101 on the right side, a containment tank 301 is fixedly installed at the bottom of the circulation seat 3, and a temperature control monitor 302 is fixedly installed at the top left side of the circulation seat 3. The temperature control monitor 302 is connected to the containment tank 301 through a pipe.

[0025] The temperature controller 302 has two interfaces on its left side. The left front interface of the temperature controller 302 is connected to one end of the pipeline A4, and the other end of the pipeline A4 is connected to the right side of the solenoid valve 203.

[0026] The left rear end interface of the temperature controller 302 is connected to one end of the pipeline B5, and the other end of the pipeline B5 is connected to the lower right side of the hydraulic press 2.

[0027] The temperature controller 302 has a cooling plate 303 fixedly installed at the top center, and a fan 304 fixedly installed at the front end of the cooling plate 303. The fan 304 is connected to the temperature controller 302 via a wiring harness.

[0028] Temperature controller 305 is installed above the right end face of temperature monitor 302. Temperature controller 305 is located to the right of cooling plate 303. Operating platform 103 is fixedly installed at the top center of device base 1. Operating platform 103 is located directly below hydraulic press 2. Pressure plate is installed at the bottom of hydraulic press 2, and the pressure plate of hydraulic press 2 is located directly above operating platform 103.

[0029] When using: During actual installation, the device base 1 serves as the basic support component of the entire device. It is placed in a suitable working area, and equipment racks 101 are fixedly installed on the top left and right sides of the device base 1. The middle position of the two equipment racks 101 is fixedly connected to the left and right ends of the mounting platform 102 using a suitable fixing method. The hydraulic press 2 is installed in the middle position of the mounting platform 102, ensuring that the hydraulic press 2 is stably installed.

[0030] Hydraulic oil is injected into the hydraulic press 2 through the injection device 201. During the injection process, the flow meter 202 is observed to ensure that the injection flow rate of the hydraulic oil meets the requirements. When the hydraulic oil reaches the appropriate level, the injection is stopped.

[0031] Place the workpiece to be processed in a suitable position on the operating table 103, connect the power and start the hydraulic press 2. The hydraulic press 2 begins to work and extend. When the bottom pressure plate of the hydraulic press 2 contacts the material on the top of the operating table 103, the entire hydraulic press 2 will be under stress. At this time, there will be a large compressive force inside the hydraulic press 2. When the system pressure reaches a certain value and an overload occurs, the temperature of the hydraulic oil inside the hydraulic press 2 will rise and transmit the temperature to the controller 204. The controller 204 receives the overload pressure of the hydraulic press 2 and sends an instruction command to the solenoid valve 203, disconnecting the solenoid valve 204. The left conical position inside the magnetic valve 203 is electromagnetically connected to the left conical position of the magnetic plug 207. After the contact position between the magnetic valve 203 and the magnetic plug 207 loses its electromagnetic connection limit, the magnetic plug 207 inside the magnetic valve 203 moves to the right under the action of the hydraulic oil pressure inside the hydraulic press 2, overcoming the elastic force of the spring 209. The synchronous telescopic rod 206 retracts, and the hydraulic oil inside the hydraulic press 2 enters the interior of the magnetic valve 203. Then, it is transferred to the temperature monitoring device 302 through pipeline A4 and then transferred to the storage tank 301 for temporary storage, which provides overload protection for the hydraulic oil inside the hydraulic press 2.

[0032] If the hydraulic oil in hydraulic press 2 becomes hot during the protection transfer, the hydraulic oil temperature can be monitored when the hydraulic oil is transferred to the temperature control monitor 302. When the high temperature occurs, the temperature control monitor 302 starts the fan 304 and cools the hydraulic oil through the cooling plate 303. The operator can observe the temperature of the hydraulic oil in real time by observing the temperature control gauge 305 to ensure that the output hydraulic oil temperature is reduced to a controllable range.

[0033] When the hydraulic oil in the hydraulic press 2 is not overloaded, the spring element 209 returns to its original position due to its own elastic force, causing the magnetic plug 207 to slide to the left inside the magnetic valve 203. The left conical position of the magnetic plug 207 then contacts the left conical position inside the magnetic valve 203. At this time, the controller 204 returns to the working state, and the magnetic plug 207 and the magnetic valve 203 are magnetically connected again. Combined with the sealing ring 208 set on the magnetic plug 207, when the magnetic plug 207 and the magnetic valve 203 are in contact, the sealing ring 208 seals the gap between the magnetic plug 207 and the magnetic valve 203, preventing the hydraulic press 2 from leaking into the magnetic valve 203.

[0034] During the resetting and retraction process of the hydraulic press 2, the receiving tank 301 feeds back the hydraulic oil to the hydraulic press 2 through the temperature control monitor 302 and pipeline B5. The temperature control monitor 302 can monitor the temperature of the hydraulic oil. At the same time, through the cooperation of the fan 304 and the cooling plate 303, the hydraulic oil is subjected to heat dissipation treatment to ensure that the temperature of the hydraulic oil after recirculation is appropriate.
