DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1-4 , a frame-type hydraulic press for water-cooled plates of new energy batteries, including a workbench 1. Pillars 3 are respectively fixed on both sides of the top end of the workbench 1. An upper crossbeam 5 is arranged at the top end of the pillar 3, and a top cover 9 is fixed at the top end of the upper crossbeam 5. Guide rails 11 are vertically installed and fixed on the right side of the left pillar 3 and the left side of the right pillar 3 respectively. A slider 4 is arranged at the bottom end of the upper crossbeam 5, and sliding frames 21 are respectively installed and fixed at the top and bottom ends on both sides of the slider 4. Tie rods 6 are respectively installed and fixed at the four corners of the top end of the upper crossbeam 5;

[0027] The top end of the pillar 3 is fixedly connected to the bottom end of the upper crossbeam 5, and the sliding frame 21 is slidably inserted outside the guide rail 11;

[0028] Specifically, as Figures 1-3 shown, the overall design of the hydraulic press adopts finite element analysis, with reasonable design and sufficient strength. The fuselage adopts a combined frame structure of the workbench 1, the pillar 3, and the upper crossbeam 5. The four tie rods 6 are locked by hydraulic overpressure. The slider 4 adopts an inclined wedge type with an overall structure of four corners and eight sides and is guided in cooperation with the guide rails 11 on both sides. The width of the guiding surface is wide, which can improve the anti-eccentric load performance, accuracy, and rigidity, and it is not easy to deviate from the accuracy after adjustment.

[0029] Embodiment 2: An installation frame 18 is installed and fixed at the front end of the right pillar 3, and a support 17 is arranged inside the installation frame 18. The left side of the support 17 penetrates through the inside of the left side of the installation frame 18 and is fixed with a fixed sleeve 15. A safety support rod 16 is fixed inside the fixed sleeve 15. Fixed frames 19 are respectively fixed at the top and bottom of the right side of the support 17, and a roller 20 is movably connected inside the top end of the fixed frame 19. Two groups of the fixed frame 19 and the roller 20 are respectively arranged at the top and bottom of the right side of the support 17, and the fixed frame 19 and the roller 20 are symmetrically arranged about the horizontal center line of the support 17;

[0030] Specifically, as Figure 1 、 Figure 3 and Figure 4As shown in the figure, a side push safety device is installed on the side of the right pillar 3. When an operator enters the interior of the hydraulic press to perform operations such as die change and die repair inside the hydraulic press, the safety lock can be electrically adjusted, which can ensure the safe operation of the press, avoid safety accidents caused by accidental falling of the internal slider 4 when personnel are operating inside the hydraulic press, protect the safety of the operator, and is designed with a side push structure. After operations such as die change and die repair are completed, just push it back to the right to leave the processing area at the bottom of the slider 4.

[0031] Embodiment 3: A main cylinder 8 is vertically installed and fixed inside the upper crossbeam 5. A filling valve 7 is installed and fixed at the top of the main cylinder 8. A fixed connection is installed between the bottom output end of the main cylinder 8 and the top of the slider 4. A servo motor 14 is fixedly installed inside the workbench 1, and a hydraulic driver 13 is fixedly installed at the top of the servo motor 14. Three groups of filling valves 7 and main cylinders 8 are respectively arranged at equal intervals;

[0032] Specifically, as Figures 1-3 shown, when the hydraulic press is in use, a servo motor 14 is equipped in the hydraulic system inside the workbench 1, which not only reduces the working noise but also greatly reduces the energy consumption. The electro-hydraulic servo drive system configured for the hydraulic press equipment is mainly driven by a dedicated hydraulic driver 13 and a servo motor 14, and can achieve closed-loop control of flow and pressure and the output hydraulic power source, overcoming the throttling and overflow losses caused by traditional asynchronous motor-driven pumps, and having the characteristics of energy conservation and consumption reduction, precise grinding control, and low noise.

[0033] During the loading and unloading stage, the ordinary motor pump group still needs to run idly, and the energy consumption at this time is about 33% of the rated power, while the servo motor 14 can stop rotating at this time, and the energy consumption is 0.

[0034] During the stage of continuous pressure application, the speed of the ordinary motor cannot change, and the motor energy consumption at this time is about 100%. All this part of the energy is converted into heat, and the temperature of the system oil increases, while the servo motor 14 can reduce its speed and can even standby at 0 rpm when the pressure is satisfied.

[0035] Due to its excellent control performance, the hydraulic press equipment system can generate less heat and can reduce the configuration requirements of the cooling device.

[0036] Due to the characteristic that the speed of the servo motor 14 can be adjusted arbitrarily, the overall noise of the hydraulic press equipment will be greatly reduced, and the no-load running noise of the equipment does not exceed 85 decibels.

[0037] Using the servo motor 14 can greatly reduce the equipment operation cost. Generally, the hydraulic press equipment system can save about 10% of energy.

[0038] A control panel 10 is fixed at the middle position of the front end of the right pillar 3. Bottom braces 12 are respectively fixed at the four corners of the bottom end of the workbench 1, and a moving table 2 is installed and fixed at the middle position of the bottom end of the workbench 1.

[0039] Working principle: The overall design of the frame - type new - energy battery water - cooled plate hydraulic press of the present utility model adopts finite - element analysis, with reasonable design and sufficient strength. The fuselage adopts a combined frame structure of the workbench 1, the pillar 3 and the upper crossbeam 5. Four tie rods 6 are locked by hydraulic over - pressure. The slider 4 adopts an inclined - wedge - type four - corner and eight - face integral type to cooperate with the two - side guide rails 11 for guiding. The width of the guiding surface is wide, which can improve the anti - off - load performance, accuracy and rigidity, and it is not easy to deviate from the accuracy after adjustment. The table surface is suitable to meet the requirements of most battery water - cooled plate molds. At the same time, a side - push safety device is installed on the side of the right pillar 3. When the operator enters the inside of the hydraulic press for operations such as die changing and die repairing, the safety lock can be electrically adjusted, which can ensure the safe operation of the press, avoid safety accidents caused by accidental falling of the internal slider 4 when the operator is operating inside the hydraulic press, and ensure the safety of the operator. With the side - push type structure design, after operations such as die changing and die repairing are completed, just push it back to the right to leave the processing area at the bottom of the slider 4. A servo motor 14 is equipped in the hydraulic system inside the workbench 1, which not only reduces the working noise but also greatly reduces the energy consumption. The electro - hydraulic servo drive system configured for the hydraulic press equipment is mainly driven by a special hydraulic driver 13 and a servo motor 14, which can achieve closed - loop control of flow and pressure and output a hydraulic power source, overcoming the throttling and overflow losses caused by the traditional asynchronous - motor - driven pump.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non - restrictive.
