Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a scratch prevention device for a shearing machine. Background Technology

[0002] In the metal processing industry, shearing machines are commonly used equipment for cutting metal sheets. Traditional methods of preventing scratches mainly rely on laying rubber pads on the shearing machine's worktable or applying anti-scratch coatings to reduce scratches on the metal sheets during the shearing process. However, after prolonged use, the surface of the rubber pads is prone to wear, leading to a weakening of the anti-scratch effect and requiring frequent replacement, increasing maintenance costs. Anti-scratch coatings may also peel off due to friction during shearing, affecting the protective effect, and recoating is time-consuming and labor-intensive. Furthermore, during shearing, the movement of the material mainly relies on direct contact friction with the inner wall of the equipment. This hard friction can damage the material surface, especially for materials with high surface quality requirements. Moreover, significant frictional resistance can also affect the material conveying speed and efficiency, increasing production costs and processing time.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the issues that rubber pads are prone to wear after prolonged use, leading to reduced scratch resistance, and that scratch-resistant coatings may peel off due to friction during shearing, affecting the protective effect and requiring time-consuming and laborious recoating; furthermore, during shearing, material movement relies primarily on direct contact friction with the inner wall of the equipment, which can damage the material surface; this application provides a scratch-resistant device for shearing machines.

[0005] The anti-scratch device for a shearing machine provided in this application adopts the following technical solution:

[0006] A scratch prevention device for a shearing machine includes a frame, a cutting base fixed in the middle of the frame, a placement platform installed on the cutting base, protective covers on both sides of the top of the cutting base, pulleys rotating inside the protective covers, cylinders installed on both sides of the pulleys, positioning blocks connected to the output ends of the cylinders, and a set of guide rollers on both sides of the cutting base.

[0007] Preferably, several rotating shafts are installed at equal intervals on both sides of the inner wall of the frame, and the guide roller is rotatably connected to the rotating shafts.

[0008] Preferably, a set of positioning stakes are symmetrically fixed to the edge of the top of the frame, and a movable rod is movably installed inside the positioning stakes.

[0009] Preferably, one end of the movable rod extends into the frame and is connected to a protective plate, and the positioning stake is threaded with a bolt for positioning the movable rod.

[0010] Preferably, the protective cover has a movable cavity in the middle that is adapted to the pulley, and a servo motor is installed at the center of the bottom of the protective cover. The output end of the servo motor extends into the movable cavity and is driven by the pulley.

[0011] Preferably, the top of the protective box cover is connected to a heightening plate by screws, and the heightening plate is internally threaded with a screw rod, one end of which is fitted with a stop block.

[0012] In summary, this application has the following beneficial technical effects:

[0013] This application, through the setting of cylinders, positioning blocks, positioning stakes, protective plates, and abutment blocks, can adapt to materials of different sizes and heights, quickly positioning the materials in the horizontal direction, providing a stable foundation for subsequent shearing operations, preventing material deviation in the lateral direction, and ensuring the accuracy of the shearing position. Furthermore, the pulley system allows for the rotation of auxiliary materials to one side, effectively protecting the surface quality of the material. For materials requiring high surface finish, such as precision instrument plates, it can prevent scratches and wear caused by friction, ensuring the integrity and quality of the material, reducing the scrap rate due to material damage. Simultaneously, reducing frictional resistance also helps improve the material conveying speed and smoothness, further enhancing the working efficiency of the shearing machine.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses an anti-scratch device for a shearing machine. (Refer to...) Figure 1 The system includes a frame 1, with a cutting base 6 fixed in the middle of the frame 1. A placement table 7 is installed on the cutting base 6. During cutting, the material is placed on the placement table 7. Several rotating shafts 3 are installed at equal intervals on both sides of the inner wall of the frame 1. A guide roller 4 is rotatably installed on the outside of the rotating shaft 3. When the material is placed, the material contacts the outer wall of the guide roller 4. The guide roller 4 rotates outside the rotating shaft 3 to assist the material in sliding, which greatly improves the material conveying efficiency and reduces the sliding resistance.

[0020] like Figure 2 As shown, a set of positioning stakes 5 are symmetrically fixed at the top edge of the frame 1. A movable rod 9 is movably installed inside the positioning stake 5. One end of the movable rod 9 extends into the frame 1 and is connected to a protective plate 10. Bolts 8 that position the movable rod 9 are threaded onto the positioning stake 5. The positioning distance of the bolts 8 to the movable rod 9 can be adjusted according to the size of the material, thereby pushing the protective plate 10 close to the outer walls of both ends of the material for positioning and support. This greatly ensures the stability of the material during the shearing process and avoids the material being displaced under force and scratching the surface.

[0021] Combination Figure 3 As shown, protective covers 2 are provided on both sides of the top of the cutting base 6. A movable cavity 11 is opened in the middle of the protective cover 2. A pulley 14 is rotatably installed inside the movable cavity 11. A servo motor 15 is installed at the center of the bottom of the protective cover 2. The output end of the servo motor 15 extends into the movable cavity 11 and is driven by the pulley 14. When the pulley 14 rotates, it can help the material to be discharged to one side, reducing the damage caused by friction between the material and the mechanical equipment, and playing a good role in guiding and protecting the material.

[0022] In this application, cylinders 12 are installed on both sides of the pulley 14. The output end of the cylinder 12 is connected to a positioning block 13. The cylinder 12 can drive the positioning block 13 to position the outer wall of the material, and then the material can be positioned on the placement table 7 for easy cutting.

[0023] In addition, the top of the protective box cover 2 is connected to a heightening plate 16 by screws. The inside of the heightening plate 16 is connected to a screw rod 17. One end of the screw rod 17 is equipped with a stop block 18. If the material is high, the screw rod 17 can be adjusted to push the stop block 18 close to the outer wall of the material for support, which greatly improves the overall versatility and provides a good protective support effect.

[0024] The implementation principle of the anti-scratch device for a shearing machine according to an embodiment of this application is as follows:

[0025] In use, the frame 1 is installed inside the shearing machine. Then, the material is placed on the guide roller 4 and pushed to one side. The guide roller 4 then rolls outside the rotating shaft 3, which helps to transport the material to the placement platform 7 at the top of the cutting base 6. Then, the positioning blocks 13 are driven to move relative to each other by the cylinders 12 on both sides. Then, the positioning blocks 13 are pressed against the outer walls of both sides of the material, which can initially position the material. Then, according to the size of the material, the movable rod 9 in the corresponding positioning stake 5 is adjusted to a suitable distance and fixed by bolts 8. Then, the edge of the material is further fixed by the protective plate 10. According to the height of the material, the screw 17 inside the heightening plate 16 can be adjusted so that the abutment block 18 is close to the top of the material, which can complete the support of the top of the material, greatly improving the stability of the material during shearing and avoiding displacement during shearing, which would cause scratches on the material surface. After shearing or during shearing, the pulley 14 can also be driven by the servo motor 15 to rotate and assist the material to move to one side, which greatly reduces frictional resistance and avoids hard friction between the material and the inner wall of the equipment, which would cause damage.
