Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic press technology, specifically to a hydraulic press with heat dissipation function. Background Technology
[0002] Hydraulic presses are important forming equipment. They are powered by an electric motor that drives a hydraulic pump to generate high-pressure fluid, which then produces linear motion through hydraulic cylinders. Due to their wide adaptability, hydraulic presses are widely used in forming processes of both metals and non-metals.
[0003] A search revealed that CN 206579185 U discloses a hydraulic press, including a body, a worktable on the body, a hydraulic cylinder inside the body above the worktable, and a pressure plate inside the body below the worktable. A pressure plate is located at the bottom end of the piston rod of the hydraulic cylinder, directly above the pressure plate. A straight guide rail is also provided on the body, parallel to the piston rod of the hydraulic cylinder. A limiting rod perpendicular to the straight guide rail is fixed on the pressure plate, with its end extending into the straight guide rail. A rectangular groove is provided inside the straight guide rail, with long pads at each of the four corners. A sliding component is provided at the end of the limiting rod, contacting each of the long pads.
[0004] Analysis revealed the following drawbacks in the actual use of this patent: during hydraulic operation, the hydraulic cylinder generates a large amount of heat as it presses downwards. In high-temperature environments, the main cylinder temperature becomes excessively high, making the hydraulic components highly susceptible to damage. This effect is particularly pronounced in summer, as the patent lacks a heat dissipation function.
[0005] In summary, this application proposes a hydraulic press with heat dissipation function to solve the aforementioned problems. Utility Model Content

The cooler is fixedly installed on the outside of the hydraulic press body, and the variable pump is fixedly installed on the outside of the cooler. A temperature sensor is installed inside the hydraulic press body, and a first controller is installed at the top of the variable pump. The first controller is electrically connected to the temperature sensor. A cooler temperature sensor is fixedly installed on the outside of the cooler, and a bellows is fixedly installed at the top of the cooler. A second controller is fixedly installed at the top of the bellows and is electrically connected to the cooler temperature sensor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a hydraulic press with heat dissipation function, including a hydraulic press body 1, a cooler 18 and a variable pump 8. The cooler 18 is fixedly installed on the outside of the hydraulic press body 1. The cooler 18 is an air-cooled cooler. The model of the cooler 18 is SJC(R)-20. The function of the cooler 18 is to dissipate heat for the hydraulic press body 1. The cooler 18 is provided with a cooler air outlet 17 on the side close to the hydraulic press body 1. The function of the air outlet 17 is to exhaust cold air for heat dissipation.
[0022] To further explain, a blower box 3 is fixedly installed on the top of the cooler 18. The blower box 3 can be a conventional small blower box, and different models can be selected according to cost. The blower box 3 has an air outlet 4 on the side near the cooler 18. The function of the blower box 3 is to dissipate heat from the body of the cooler 18 through the air outlet 4.
[0023] A cooling temperature sensor 14, model LM-400, is fixedly installed on the outside of the cooling unit 18. A second controller 19, model SN-501, is fixedly installed on the top of the air box 3. The second controller 19 is electrically connected to the cooling temperature sensor 14. The cooling temperature sensor 14 detects the body temperature of the cooling unit 18. When the temperature is too high, the cooling temperature sensor 14 sends a signal to the second controller 19, which then controls the air box 3 to operate and dissipate heat from the body of the cooling unit 18.
[0024] To further explain, a variable pump 8, model A7V8, is fixedly installed externally on the cooler 18. The function of the variable pump 8 is to control the power of the cooler 18.
[0025] A temperature sensor 10, model LM-400, is installed inside the hydraulic press body 1. The function of the temperature sensor 10 is to detect the temperature of the worktable 13 when the hydraulic press body 1 is working. A first controller 7, model SN-501, is installed on the top of the variable pump 8. The first controller 7 is electrically connected to the temperature sensor 10. The temperature sensor 10 transmits the received signal to the first controller 7. The higher the temperature of the hydraulic press body 1, the stronger the signal transmission. According to the signal strength, the first controller 7 controls the variable pump 8 to adjust the power of the cooler 18 accordingly. At the same time, the cooling box 3 on the cooler 18 and the variable pump 8 drive the cooler 18 to dissipate heat from the hydraulic press body 1, forming a heat dissipation cycle, thereby completing the entire heat dissipation work. Different temperatures correspond to different efficiencies, which greatly reduces energy consumption and further reduces costs.
[0026] To further explain, the variable pump 8 is fixedly mounted with a variable pump base and a support leg 9 at its bottom. The variable pump base and support leg 9 are used to provide a certain support for the variable pump, and any material can be used to achieve the support purpose.
[0027] The hydraulic press body 1 is model ZQ 3032. The main cylinder 2 is fixedly installed at the top of the hydraulic press body 1. The main cylinder 2 is used to push the device downward. The upper crossbeam 16 is fixedly installed below the main cylinder 2, and the upper crossbeam 16 supports the main cylinder 2.
[0028] To further explain, a piston shaft 20 is fixedly installed below the upper crossbeam 16, and the piston shaft 20 passes through the upper crossbeam 16. The piston shaft 20 is connected to the main cylinder 2 and is the main hydraulic power source of the hydraulic press body 1. A column 6 is fixedly installed at the bottom of the upper crossbeam 16. The column 6 supports the upper crossbeam 16 and connects to the ejector cylinder 15. Rubber rings 5 are fixedly installed on the outside of the column 6 and the piston shaft 20. The rubber rings 5 are located at the upper and lower connections of the column 6, the piston shaft 20, the upper crossbeam 16, and the ejector cylinder 15. In order to extend the service life of the hydraulic device, if it is considered that the rubber rings 5 are easily damaged in high temperature environments, other high temperature resistant materials can be selected to replace them to provide a certain degree of protection.
[0029] A ejector cylinder 15 is fixedly installed at the bottom end of the piston shaft 20. The function of the ejector cylinder 15 is to eject the device upward after the main cylinder 2 is pressed downward. A worktable 13 is provided at the bottom end of the ejector cylinder 15. The worktable 13 is the storage place for pressurized materials and is the main working place of the hydraulic press body 1. A hydraulic plate 11 is provided on the worktable 13. The upper hydraulic plate 11 is fixedly connected to the ejector cylinder 15, so that the piston shaft 20 is pressed after the main cylinder 2 moves downward. The lower hydraulic plate 11 is fixedly installed in the worktable 13 and is symmetrical with the upper hydraulic plate 11. The two are combined to form a hydraulic plate device.
[0030] Specifically, a hydraulic press base 12 is fixedly installed at the bottom of the hydraulic press body 1, and the hydraulic press base 12 provides support for the hydraulic press body 1.
[0031] For specific operation, please refer to the following instructions: During hydraulic operation, after the hydraulic press body 1 starts running, the temperature of the device itself gradually increases. The temperature sensor 10 installed inside the hydraulic press body 1 transmits signals of different intensities to the first controller 7 on the variable pump 8 according to the temperature. The first controller 7 controls the air outlet rate of the cooler 18 through the variable pump 8 according to the temperature, and dissipates heat from the hydraulic press body 1 according to different temperatures. When the working power of the cooler 18 is high, the cooler temperature sensor 14 transmits a signal to the second controller 19 on the air box 3. The second controller 19 then controls the air box 3 to start dissipating heat from the cooler 18 body, further improving the working efficiency of the cooler 18, thereby improving the working efficiency of the entire cooling mechanism, realizing the cycle of cooling and heat dissipation function, and reducing unnecessary energy consumption.
