Description

Technical Field

[0001] This utility model relates to the field of hydraulic cutting machine technology, and in particular to a safety protection structure for a four-column hydraulic cutting machine. Background Technology

[0002] In the production and processing of handicrafts, a four-column hydraulic cutting machine is required. The cutting machine uses the force of the machine's movement to press the die and punch non-metallic materials. In practical applications, the four-column hydraulic cutting machine requires the operator to hold the side of the pull-out cutting board to perform the corresponding pulling operation. If the machine malfunctions or if the operator is not careful, it may cause injury to the operator's hands. Therefore, it is necessary to protect the device through a safety protection structure.

[0003] The patent with publication number CN214604728U proposes a safety protection structure for a four-column hydraulic cutting machine, which includes a four-column hydraulic cutting machine body, a pull-out cutting plate, a fixed angle steel and auxiliary rollers. The pull-out cutting plate is located on the worktable of the four-column hydraulic cutting machine body.

[0004] In the above case, the cutting plate is supported by a fixed angle steel and auxiliary rollers fixed to the cutting machine, and then pulled by a sleeve threaded to the inside of the cutting plate. However, because the fixed angle steel is fixed to the outside of the cutting machine, it is difficult to disassemble and replace the protective mechanism after it gets dirty or damaged. It also increases the size of the cutting machine, making it inconvenient to transport and store. Furthermore, the mechanism does not limit the displacement trajectory of the cutting plate, which makes it easy for it to deviate when moving on the fixed angle steel, making it difficult to place it upright inside the cutting machine and reducing the practicality of the structure. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection structure for a four-column hydraulic cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection structure for a four-column hydraulic cutting machine, comprising a mounting plate and a cutting machine body. The inner sides of both ends of the mounting plate are provided with side grooves. A fixing component is rotatably connected to one side of the mounting plate. Both ends of the fixing component pass through the side grooves on both sides and are clamped to the outside of the cutting machine body. A cutting plate is placed inside the cutting machine body. A guide component is fixedly connected to the top of the mounting plate, and the cutting plate is snapped into the inner side of the guide component. A support component is fixedly connected to the top of the mounting plate on the side away from the cutting machine body.

[0007] In a preferred embodiment, the fixing component includes a bidirectional lead screw rotatably connected to the outside of the mounting plate. Both ends of the bidirectional lead screw are threadedly connected to drive blocks. A clamping plate is fixedly connected to the side of the drive block near the cutting machine body.

[0009] In a preferred embodiment, the support assembly includes two support plates that are respectively fixedly connected to both ends of the mounting plate, and a plurality of rollers are rotatably connected to the inner side of the support plates.

[0010] In a preferred embodiment, the height of the top of the roller is the same as the height of the bottom of the cutting board, and the two adjacent sides of the support plates are fixedly connected with reinforcing bars, and their other ends are fixedly connected to the mounting plate.

[0011] In a preferred embodiment, the guide assembly includes two guide plates that are respectively fixedly connected to the top ends of the mounting plate. The guide plates have grooves on their inner sides, and sliders are slidably connected to the inner sides of the grooves. The adjacent sides of the two sliders are fixedly connected to fixed plates, and the top ends of the two sliders are fixedly connected to the same connecting frame.

[0012] In a preferred embodiment, the two fixing plates are tightly fitted to both sides of the cutting plate. A baffle is fixedly connected to the side of the adjacent ends of the two fixing plates near the mounting plate. An inner groove is opened at the end of the fixing plate away from the baffle.

[0019] Please see Figures 1-4This utility model provides a safety protection structure for a four-column hydraulic cutting machine, including a mounting plate 1 and a cutting machine body 15. The inner sides of both ends of the mounting plate 1 are provided with side grooves 2. A fixing component is rotatably connected to one side of the mounting plate 1. Both ends of the fixing component pass through the side grooves 2 on both sides and are clamped to the outside of the cutting machine body 15. A cutting plate 16 is placed inside the cutting machine body 15. The cutting machine body 15 and the mounting plate 1 are tightly fitted. A guide component is fixedly connected to the top of the mounting plate 1. The cutting plate 16 is snapped into the inner side of the guide component.

Both ends of the bidirectional lead screw 4 are threadedly connected to drive blocks 3. A clamping plate 5 is fixedly connected to the side of the drive block 3 near the cutting machine body 15. The drive block 3 is slidably connected to the inner side of the side groove 2 on the same side. The two clamping plates 5 are tightly fitted to the two ends of the outer side of the cutting machine body 15. A first- and second-reverse motor is fixedly connected to the outer side of the mounting plate 1. Its output end is fixedly connected to the bidirectional lead screw 4. The guide assembly includes two guide plates 8 fixedly connected to the top ends of the mounting plate 1. A sliding groove 9 is opened on the inner side of the guide plate 8. A slider 10 is slidably connected to the inner side of the sliding groove 9. A fixing plate 11 is fixedly connected to the adjacent sides of the two sliders 10.

[0020] Place the mounting plate 1 at a suitable position on the outside of the cutting machine body 15. The two fixing plates 11 are located on both sides of the cutting plate 16, and their bottoms are attached to the bottom of the inner side of the cutting machine body 15. The bidirectional lead screw 4 is driven by the No. 1 forward and reverse motor. The drive block 3 slides along the side groove 2 under the action of the thread of the bidirectional lead screw 4. The clamping plate 5 moves accordingly. Finally, the clamping plate 5 is tightly attached to both ends of the outside of the cutting machine body 15, and the mounting plate 1 is fixed to the outside of the cutting machine body 15.

[0021] When the bidirectional lead screw 4 rotates, it can drive the drive blocks 3 on both sides to move synchronously in opposite directions within the corresponding inner grooves 13, so that the two clamping plates 5 can be tightly clamped on the outside of the cutting machine body 15. This design not only makes the entire mechanism easy to disassemble and assemble, but also allows for flexible adjustment according to various cutting machines of different sizes, ensuring that it can be firmly fixed on the outside of the cutting machine. This makes the mechanism applicable to various cutting machines of different specifications, with wide applicability. In addition, this structure also makes the entire mechanism easy to store and maintain, greatly improving the ease of use of the equipment.

[0022] Please see Figures 1-4A support assembly is fixedly connected to the top of the mounting plate 1 on the side away from the cutting machine body 15. The support assembly includes two support plates 6 fixedly connected to both ends of the mounting plate 1. Several rollers 7 are rotatably connected to the inner side of the support plates 6. The height of the top of the rollers 7 is the same as the height of the bottom of the cutting plate 16. Reinforcing bars are fixedly connected to the adjacent sides of the two support plates 6, and their other ends are fixedly connected to the mounting plate 1. The top of the two sliders 10 is fixedly connected to the same connecting frame 17. The two fixed plates 11 are tightly fitted to both sides of the cutting plate 16. A baffle 12 is fixedly connected to the side of the adjacent ends of the two fixed plates 11 near the mounting plate 1. An inner groove 13 is opened at the end of the fixed plate 11 away from the baffle 12. A rotating plate 14 is rotatably connected to the end of the inner groove 13 near the baffle 12. The baffle 12 and the rotating plate 14 are tightly fitted to the front and rear ends of the cutting plate 16. A second forward and reverse motor is fixedly connected to the top of the fixed plate 11. Its output end extends to the inner side of the fixed plate 11 and is fixedly connected to the rotating plate 14 on the same side.

[0023] Two rotating plates 14 are driven by a second forward and reverse motor to rotate, so that the rotating plates 14 are in close contact with the cutting plate 16. The connecting frame 17 is pulled by a handle fixedly connected to one side, so that the sliders 10 on both sides slide in the slide groove 9, which drives the fixed plate 11 and the rotating plate 14 to move, pulling the cutting plate 16 out from the inside of the cutting machine body 15. The roller 7 supports and assists the movement of the cutting plate 16. After the cutting plate 16 is completely pulled out, the raw materials of the craft to be processed are placed on the cutting plate 16, and then the cutting plate 16 is pushed back to its original position by the connecting frame 17, and the cutting work is performed by the cutting machine body 15.

[0024] The cutting plate 16 can be fixed between the two fixed plates 11 using the rotating plate 14 and the baffle 12. This not only ensures the stability of the cutting plate 16 during the cutting process, but also allows the connecting frame 17 to drag the two sliders 10 smoothly within the slide groove 9 when the cutting plate 16 needs to be moved. This allows the two fixed plates 11 to slide smoothly inside the two guide plates 8. This design limits the displacement track of the cutting plate 16, effectively preventing the cutting plate 16 from shifting during the sliding process and ensuring that it can accurately move to the middle position within the cutting machine body 15. This precise displacement control and improved stability not only improve the accuracy and quality of the cutting, but also enhance the reliability and safety of the entire mechanism during operation, greatly improving the overall performance and service life of the mechanism.

[0025] The working principle and usage process of this utility model are as follows: The mounting plate 1 is placed at a suitable position on the outside of the cutting machine body 15. Two fixing plates 11 are located on both sides of the cutting plate 16, with their bottoms fitting against the inner bottom of the cutting machine body 15. The bidirectional lead screw 4 is driven by a first-stage forward and reverse motor. The driving block 3 slides along the side groove 2 under the action of the thread of the bidirectional lead screw 4, and the clamping plate 5 moves accordingly. Finally, the clamping plate 5 is tightly fitted against both ends of the outer side of the cutting machine body 15, fixing the mounting plate 1 to the outside of the cutting machine body 15. The two rotating plates are then driven by a second-stage forward and reverse motor. Rotate plate 14 so that it is pressed against cutting plate 16. Pull the connecting frame 17 through the handle fixedly connected to one side of the connecting frame 17 so that the sliders 10 on both sides slide in the slide groove 9, driving the fixed plate 11 and the rotating plate 14 to move, pulling the cutting plate 16 out from the inside of the cutting machine body 15. The roller 7 supports and assists the movement of the cutting plate 16. After the cutting plate 16 is completely pulled out, place the craft material to be processed on the cutting plate 16, and then push the cutting plate 16 back to its original position through the connecting frame 17. The cutting work is then carried out by the cutting machine body 15.

[0026] In the above scheme, it should be noted that: the cutting machine body 15 of this application is an existing four-column hydraulic cutting machine, and the specific structure, electrical connection method and cutting principle of the cutting machine body 15 are all existing publicly available technical means, which will not be described in detail here.
