Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and more specifically, to a servo hydraulic press. Background Technology

[0002] The new type of servo-driven hydraulic press (hereinafter referred to as servo hydraulic press) is an energy-saving and high-efficiency hydraulic press that uses a servo motor to drive the main transmission oil pump, reduces the control valve circuit, and controls the hydraulic press slide. It is suitable for processes such as stamping, die forging, press fitting, and straightening. A servo hydraulic press is required when processing workpieces.

[0003] In existing hydraulic presses, the installation of the upper and lower molds typically involves using fixing bolts and specialized tools. While this method effectively secures the molds, it is time-consuming and labor-intensive, reducing the efficiency of mold assembly and disassembly, increasing the workload of operators, and causing bolts to loosen over time. This can lead to safety hazards during operation. Furthermore, traditional hydraulic presses often lack protective structures for the control panel, which is typically exposed to the environment when not in use. This allows dust and other impurities to accumulate, potentially causing damage. Accidental impacts from external objects can also damage the control panel, reducing the overall lifespan and usability of the hydraulic press.

[0004] Compared with Chinese Patent Publication No. CN216443118U, this utility model discloses a servo hydraulic press, including a base, a platform, and a gantry frame. A fixed seat is mounted on the platform, and the fixed seat is detachably connected to a mold base via a first fixing screw passing through the bottom of the platform. A mold core is provided on the mold base. A hydraulic cylinder is mounted on the top of the gantry frame, and the hydraulic cylinder is connected to a pressing mechanism paired with the mold base via a pressure rod. The mold base and the pressing mold are detachably installed via a first fixing screw and a second assembly screw hole, facilitating the matching of workpieces of different sizes. Simultaneously, a limiting device connected to the pressing mechanism prevents the pressing mechanism from shifting left and right. The left and right positions are restricted by the swing arm and the limiting slide, greatly improving the precision of the fit between the pressing mold and the mold base, thereby improving the stamping quality of the product and reducing the defect rate. Synchronous descent and ascent are achieved through synchronously moving pressure rods and push rods, ensuring the pressing position of the pressing mold.

[0005] The above solution can effectively replace the upper and lower molds, but it still uses bolts to replace them. Furthermore, the solution cannot effectively protect the control panel and fails to solve the problems mentioned in the background section.

[0006] Therefore, those skilled in the art have provided a servo hydraulic press to solve the problems mentioned in the background art. Utility Model Content

[0032] 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 protection scope of the present utility model.

[0033] Please see Figure 1 - Figure 8 As shown, this embodiment provides a servo hydraulic press, including a processing table 1, and further comprising:

[0034] The positioning frame 2 is fixedly connected to the upper surface of the processing table 1. The interior of the positioning frame 2 is provided with a mounting plate 3, and the upper surface of the mounting plate 3 is fixedly connected with a lower mold 4.

[0035] The first mounting component is set on both sides of the outer wall of the positioning frame 2 and is used to fix the mounting plate 3 to the positioning frame 2.

[0036] Support frame 6 is fixedly connected to the upper surface of processing table 1. A fixed frame 7 is fixedly connected to the upper surface of support frame 6. A lifting cylinder 8 is fixedly connected to the bottom of fixed frame 7. An installation cylinder 9 is fixedly connected to the telescopic end of lifting cylinder 8. An installation column 13 is provided inside the installation cylinder 9. An upper mold 10 is fixedly connected to the bottom of installation column 13.

[0037] The second mounting assembly is symmetrically arranged on the outside of the mounting cylinder 9 and is used to fix the mounting cylinder 9 and the mounting post 13.

[0038] The control box 12 is fixedly installed on one side of the processing table 1, and the upper surface of the control box 12 is provided with a control screen 14.

[0039] A protective component is installed on the upper surface of the control box 12 and is used to protect the control panel 14.

[0040] The working principle described above is as follows: When the specifications and shape of the lower mold 4 need to be changed according to actual needs, the mounting plate 3 and the positioning frame 2 can be easily disassembled using the first mounting component, making it convenient for workers to disassemble and replace the lower mold 4. When the specifications and shape of the upper mold 10 need to be changed according to actual needs, the mounting cylinder 9 and the mounting column 13 can be easily disassembled using the second mounting component, making it convenient for workers to disassemble and replace the upper mold 10. Furthermore, this device does not require the use of bolts or other tools when disassembling and assembling the upper mold 10 and the lower mold 4, effectively improving the efficiency of disassembly and assembly of the upper mold 10 and the lower mold 4 and reducing the workload of workers. When the device as a whole is not needed, the control panel 14 on the upper surface of the control box 12 can be effectively protected using the protective component, thereby effectively extending the service life of the control panel 14 and the entire device, saving time and effort.

[0041] To facilitate the fixed installation of the lower mold 4, the first installation component includes a fixed plate 5 fixedly connected to both sides of the outer wall of the positioning frame 2. The fixed plate 5 has symmetrically arranged sliding rods 21 inside, with both ends of the sliding rods 21 fixedly connected to both sides of the inner wall of the fixed plate 5. The fixed plate 5 also has a movable plate 22 inside, with guide grooves for the sliding rods 21 to move. Each sliding rod 21 is fitted with a return spring 23, which abuts against the movable plate 22 and the fixed plate 5. A pull plate is fixedly connected to the outside of the movable plate 22 via a side plate 24. Fixed rods 25 are symmetrically arranged on opposite sides of the two movable plates 22. Guide grooves for the fixed rods 25 are provided on the contact surfaces between the fixed plate 5 and the positioning frame 2. Guide grooves for the fixed rods 25 are also provided on both sides of the outer wall of the mounting plate 3. When it is necessary to adjust the lower mold 4... When fixing and installing mold 4, simply pull the pull plate first. The pull plate will move the side plate 24 synchronously. The side plate 24 will then move the moving plate 22 synchronously outside the slide rod 21. During the movement of the moving plate 22, it will compress the return spring 23. The moving plate 22 will also move the fixing rod 25 synchronously. Then, insert the mounting plate 3 into the positioning frame 2 and release the pull plate. The return spring 23 will then return to its original position and move the moving plate 22 synchronously. The moving plate 22 will then move the fixing rod 25 synchronously. When the fixing rod 25 is inserted into the guide grooves on both sides of the outer wall of the mounting plate 3, the mounting plate 3 and the positioning frame 2 can be fixed. At this time, the lower mold 4 can be fixed, which also makes it easier for workers to disassemble and replace the lower mold 4, effectively improving the disassembly and assembly efficiency of the lower mold 4.

[0042] Considering that after the mounting plate 3 and the positioning frame 2 are fixed together, it is necessary to further improve the fixing effect between the mounting plate 3 and the positioning frame 2, the upper surface of the positioning frame 2 is symmetrically provided with cross positioning plates 20, and the bottom of the mounting plate 3 is provided with a guide groove for the cross positioning plates 20 to move. After the mounting plate 3 and the positioning frame 2 are fixed together, the cross positioning plates 20 will also be inserted into the guide groove at the bottom of the mounting plate 3. At this time, the fixing effect between the mounting plate 3 and the positioning frame 2 can be further improved by the cross positioning plates 20, thereby effectively improving the stability of the lower mold 4.

[0043] To facilitate the fixed installation of the upper mold 10, the second installation component includes fixed sleeves 11 symmetrically arranged outside the installation cylinder 9. An installation rod 26 is located inside the fixed sleeve 11. One end of the installation rod 26 is fixedly connected to a pull plate, and an abutment plate 27 is fixedly connected to the outside of the installation rod 26. An abutment spring 28 is sleeved on the outside of the installation rod 26, abutting between the abutment plate 27 and the fixed sleeve 11. Guide grooves for the movement of the installation rod 26 are provided on the contact surfaces of the fixed sleeve 11 and the installation cylinder 9. A guide groove for the movement of the installation rod 26 is also provided inside the installation column 13. When the upper mold 10 needs to be fixed, simply pull the pull plate first. The pull plate will drive the mounting rod 26 to move synchronously, and the mounting rod 26 will then drive the abutment plate 27 to move synchronously. During the movement of the abutment plate 27, the abutment spring 28 will be compressed. At this time, the mounting post 13 is inserted into the interior of the mounting cylinder 9, and then the pull plate is released. At this time, the abutment spring 28 returns to its original position, driving the abutment plate 27 and the mounting rod 26 to move synchronously. When the mounting rod 26 is inserted into the interior of the mounting post 13, the mounting post 13 and the mounting cylinder 9 can be fixed. At this time, the upper mold 10 can be fixedly installed, and it is also convenient for the staff to disassemble and replace the upper mold 10, which effectively improves the disassembly and assembly efficiency of the upper mold 10 and reduces the workload of the staff.

[0044] To effectively improve the stability of the upper mold 10 during movement, support plates 33 are symmetrically provided on the outside of the support frame 6. Guide rods 34 are symmetrically provided at the bottom of both support plates 33. Guide plates 35 are symmetrically provided on the outside of the mounting cylinder 9. Guide grooves for the guide rods 34 to move are opened inside both guide plates 35. During the movement of the mounting cylinder 9, the guide plates 35 will move synchronously outside the guide rods 34. At this time, the stability of the mounting cylinder 9 during movement can be effectively improved by the cooperation between the guide plates 35 and the guide rods 34, thereby effectively improving the stability of the upper mold 10 during movement.

[0045] In addition, to effectively protect the control panel 14, the protective components include a protective cover 17 hinged to the upper surface of the control box 12. The upper surface of the control box 12 is symmetrically provided with mounting frames 15. The upper surfaces of both mounting frames 15 have guide grooves for the movement of the protective cover 17. A plug plate 18 is fixedly connected to the front end surface of the protective cover 17. A U-shaped frame 16 is fixedly connected to the upper surface of the control box 12. An inner plate 29 is fixedly connected inside the plug plate 18. Telescopic rods 30 are fixedly connected to both sides of the outer wall of the inner plate 29. Hemispherical blocks 31 are fixedly connected to the telescopic ends of both telescopic rods 30. Connecting springs 32 are sleeved on the outside of both telescopic rods 30, and both connecting springs 32 abut against the hemispherical blocks 31 and the inner plate 29. Guide grooves for the movement of the hemispherical blocks 31 are provided on both sides of the outer walls of the plug plate 18 and the U-shaped frame 16. When protection of the control panel 14 is required, the protective cover 17 only needs to be closed first. At this time, the protective cover 17... 7 will drive the insert plate 18 to move synchronously, and the insert plate 18 will then drive the hemispherical block 31 to move synchronously. When the insert plate 18 moves into the inside of the C-shaped frame 16, the hemispherical block 31 will be squeezed. At this time, the hemispherical block 31 will squeeze the telescopic rod 30 and the connecting spring 32 synchronously. When the insert plate 18 drives the hemispherical block 31 to move into the guide grooves on both sides of the outer wall of the C-shaped frame 16, the connecting spring 32 will reset and drive the hemispherical block 31 to move synchronously. When the hemispherical block 31 is inserted into the guide grooves on both sides of the outer wall of the C-shaped frame 16, the insert plate 18 and the C-shaped frame 16 can be fixed. At this time, the protective cover 17 can be fixed, so that the protective cover 17 can effectively protect the control screen 14, thereby effectively extending the service life of the control screen 14 and the entire device. The setting of the mounting frame 15 makes it easy for the staff to close and position the protective cover 17, thereby effectively improving the stability of the protective cover 17.

[0046] To further improve the overall safety of the device, safety light curtains 19 are symmetrically provided on the upper surface of the processing table 1. When the operator's hand moves between the two safety light curtains 19, the safety light curtains 19 will detect the signal and transmit the signal to the controller. The controller will then control the device to stop working, thereby avoiding injury to the operator's hand and effectively improving the overall safety of the device.
