Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic presses, and more specifically, it relates to an energy-saving device for hydraulic presses. Background Art
[0002] In the existing technology, when the current hydraulic press processes raw materials, it usually needs to rely on additional positioning equipment to ensure the precise position of the workpiece. This design increases the complexity of the production line, resulting in an increase in production costs. The additional equipment not only increases the investment cost, but also requires more maintenance and operation, thus wasting precious resources and time. In addition, this dependence also limits the flexible application of the hydraulic press in different production environments, affecting its versatility and adaptability.
[0003] In terms of the connection method between the hydraulic cylinder and the platen of the hydraulic press, the existing design is relatively complex, usually involving the cooperation of multiple components and fasteners. This complex connection method not only increases the difficulty of assembly and maintenance, but also may lead to insecure connection or leakage. In actual operation, it takes a lot of effort to install and disassemble, increasing the labor intensity of workers and may also lead to operation errors and safety hazards.
[0004] In the hydraulic process of the existing hydraulic press, it is often unable to effectively collect the dropped workpieces, waste materials and possibly leaked oil. This will not only cause pollution to the working environment, increase the cost of cleaning and maintenance, but also may violate strict environmental protection regulations. Due to the lack of an effective collection mechanism, these wastes and liquids may be directly discharged into the environment, causing damage to the ecosystem. Therefore, there is a need to improve the design of the hydraulic press to include an effective waste and liquid collection system. Summary of the Utility Model

[0037] A protective net 32 is provided on the hydraulic body 1.
[0038] In this embodiment, the telescopic rod 4 is pulled to drive the clamping block 7 to move outward. The clamping block 7 slides outward along the mounting plate 3 through the sliding rod 5. Then, the workpiece to be hydraulically processed is placed between the clamping blocks 7. Then, the telescopic rod 4 is released, so that the return spring 6 provided on the outer wall of the sliding rod 5 rebounds to push the clamping block 7 to reset. After that, the clamping block 7 positions and clamps the workpiece. The arc-shaped block 10 is installed on both sides of the telescopic end of the hydraulic cylinder 8. Then, multiple groups of insertion blocks 13 provided at the top of the pressing plate 9 are inserted into the insertion tube 11. The pull head 21 is pulled to drive the sliding tube 17 to slide along the insertion tube 11 through the pull rod 20. At this time, the convex ring 19 provided on the inner wall of the sliding tube 17 disengages from the moving positions of multiple groups of insertion balls 12. At this time, the insertion block 13 pushes up the insertion balls 12, so that the insertion block 13 can be smoothly inserted into the insertion tube 11. When the insertion slot 14 moves to the position of the insertion balls 12, the pull head 21 is released, and the third spring 18 rebounds the sliding tube 17, so that the convex ring 19 provided on the inner wall of the sliding tube 17 pushes the insertion balls 12 out of the inner wall of the insertion tube 11, so that the insertion balls 12 are stuck in the insertion slot 14, thereby completing the clamping installation of the insertion tube 11 and the insertion block 13.

During the pulling-out process, due to the rebounding properties of the first spring 22 and the second spring 24 on the first top block 23 and the second top block 25, the insertion block 13 can automatically pop out of the insertion tube 11.
[0039] Please refer to Figure 2 , as an implementation mode of an energy-saving device for a hydraulic press for the collection mechanism: a collection mechanism is provided below the hydraulic body 1.

The cabinet door 28 is installed on the cabinet. The mounting groove 29 is provided on the hydraulic body 1. The collection pipe 30 is provided on the bottom surface of the bottom plate 2. The collection box 31 is provided on the bottom surface of the mounting groove 29.
[0040] A protective net 32 is provided on the hydraulic body 1.
[0041] More specifically, through the leakage hole 27, the workpieces dropped during the hydraulic process, the leaked oil and fertilizers can be gathered. After gathering, they are transported to the collection box 31 through the material collection pipe. The cabinet door 28 is opened to take the collection box 31 out of the machine shell.
[0042] In summary, when the overall device is in use or operation: Pull the telescopic rod 4 to drive the clamping block 7 to move outward. The clamping block 7 slides outward along the mounting plate 3 through the sliding rod 5. Then, place the workpiece to be hydraulically processed between the clamping blocks 7. Then, release the telescopic rod 4 so that the return spring 6 provided on the outer wall of the sliding rod 5 rebounds to push the clamping block 7 to reset. After that, make the clamping block 7 position and clamp the workpiece. Install the arc-shaped block 10 on both sides of the telescopic end of the hydraulic cylinder 8. Then, insert the multiple groups of insertion blocks 13 provided at the top of the pressing plate 9 into the insertion tube 11. Pull the pull head 21 to drive the sliding tube 17 to slide along the insertion tube 11 through the pull rod 20. At this time, the convex ring 19 provided on the inner wall of the sliding tube 17 disengages from the movable positions of the multiple groups of insertion balls 12. At this time, the insertion block 13 pushes up the insertion balls 12 so that the insertion block 13 can be smoothly inserted into the insertion tube 11. When the insertion slot 14 moves to the position of the insertion balls 12, release the pull head 21 so that the third spring 18 rebounds the sliding tube 17, making the convex ring 19 provided on the inner wall of the sliding tube 17 push the insertion balls 12 out of the inner wall of the insertion tube 11, so that the insertion balls 12 are stuck in the insertion slot 14, thereby completing the clamping installation of the insertion tube 11 and the insertion block 13. Similarly, by pulling the sliding tube 17 with the pull head 21 and the pull rod 20 to make the convex ring 19 contact and abut against the insertion balls 12, the insertion block 13 can be pulled out of the insertion tube 11. During the pulling-out process, due to the rebounding properties of the first spring 22 and the second spring 24 on the first top block 23 and the second top block 25, the insertion block 13 can automatically pop out of the insertion tube 11.
[0043] Through the leakage hole 27, the workpieces, leaked oil and fertilizers that fall during the hydraulic process can be gathered. After gathering, they are conveyed to the collection box 31 through the material collection pipe. Open the cabinet door 28 of the machine shell to take the collection box 31.
