Description

Technical Field

[0001] This utility model belongs to the technical field of gantry shearing machines, specifically relating to a self-lubricating device for the roller guide rail of the moving blade holder of a gantry shearing machine. Background Technology

[0002] After recycling, scrap metal needs to be cut and crushed by various equipment to facilitate subsequent processing. Gantry shears are commonly used for cutting and crushing due to their advantages of high shearing force and ease of use. Currently, gantry shears are usually fixed to the ground. Before fixing them, ground leveling and foundation construction are required. During operation, scrap metal needs to be transported to the shear's working area, cut, and then transported to other work sites. This necessitates setting up the shear in a sufficiently large space for efficient cutting and transport of scrap metal.

[0003] Existing lubrication methods typically involve manual, periodic addition of lubricating oil, which is cumbersome and difficult to ensure uniform lubrication. Insufficient lubrication can easily lead to increased wear on the guide rails. Some equipment uses oil-impregnated bearings or self-lubricating materials, but the lubrication effect decreases after long-term use, requiring periodic replenishment of lubricating oil. Furthermore, these methods are not suitable for high-load, high-frequency shearing machine operations. To address these issues, we have designed a self-lubricating roller guide rail device for the moving blade holder of a gantry shearing machine, providing an alternative technical solution.

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.

[0016] Reference Figure 1-8 A self-lubricating device for the roller guide rail of a gantry shearing machine includes a small mobile blade holder 1. Both ends of the bottom of the small mobile blade holder 1 are fixed with horizontal sliders 3. The bottom of the horizontal sliders 3 is slidably connected with a horizontal guide rail 2. Horizontal rollers 4 are provided at both ends and sides of the bottom of the horizontal sliders 3. A vertical rotating column 5 is fixed inside the horizontal rollers 4. The vertical rotating column 5 passes through the interior of the horizontal sliders 3 and is rotatably connected to the horizontal sliders 3 through bearings. The interior of the horizontal slider 3 is equipped with an oil injection mechanism for injecting oil into the outside of the vertical rotating column 5; The oil injection mechanism includes a drive motor 6. One end of the transverse slider 3 is bolted to the drive motor 6. A first longitudinal threaded rod 10 is fixed to the output end of the drive motor 6. A second longitudinal threaded rod 11 is provided at one end of the first longitudinal threaded rod 10. The threads of the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 have opposite directions. Both the outer sides of the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 are threaded to longitudinal sliders 13. Both ends of the longitudinal sliders 13 are rotatably connected to inclined rotating columns 14 via pins. A transverse sliding column 15 is rotatably connected to one side of the inclined rotating column 14. One end of the transverse sliding column 15 is fixed to... The rectangular extrusion plate 9, through the operation of the drive motor 6, enables the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 to rotate. The rotation of the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 enables the longitudinal connecting rod 12 to rotate inside the transverse slider 3. The rotation of the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 enables the longitudinal slider 13 to move inside the transverse slider 3. The movement of the longitudinal slider 13, through the oblique rotating column 14, enables the transverse sliding column 15 to move inside the transverse slider 3, thereby enabling the two rectangular extrusion plates 9 to move.

[0017] The interior of the horizontal slider 3 has a rectangular through hole. The horizontal sliding column 15 is located inside the rectangular through hole and is slidably connected to the horizontal slider 3 through the rectangular through hole. The rectangular through hole allows the horizontal sliding column 15 to move inside the horizontal slider 3. The movement of the horizontal sliding column 15 allows the rectangular extrusion plate 9 to move inside the horizontal slider 3. A rectangular oil storage chamber 8 is provided inside the horizontal slider 3 and outside the rectangular extrusion plate 9. A horizontal lubricating oil through hole 7 is provided at one end of the rectangular oil storage chamber 8 near the vertical rotating column 5. An oil injection hole is provided at the top of the rectangular oil storage chamber 8. The oil injection hole is located inside the horizontal slider 3. Through the setting of the oil injection hole, lubricating oil can be injected into the interior of the rectangular oil storage chamber 8. By moving the rectangular extrusion plate 9, the lubricating oil inside the rectangular oil storage chamber 8 is injected into the outside of the vertical rotating column 5 through the horizontal lubricating oil through hole 7, so that the vertical rotating column 5 can rotate inside the horizontal slider 3. The rectangular extrusion plate 9 is located inside the rectangular oil storage chamber 8 and is slidably connected to the rectangular oil storage chamber 8, thereby enabling the rectangular extrusion plate 9 to move inside the rectangular oil storage chamber 8. The movement of the rectangular extrusion plate 9 enables the lubricating oil inside the rectangular oil storage chamber 8 to be extruded. A longitudinal connecting rod 12 is fixed between the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11. The longitudinal connecting rod 12 passes through the interior of the transverse slider 3 and is rotatably connected to the transverse slider 3 through a bearing, thereby enabling the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 to rotate more synchronously. Through the setting of the bearing, the longitudinal connecting rod 12 can rotate inside the transverse slider 3. The top and bottom of the vertical slider 13 are fixed with dovetail sliders, and the interior of the horizontal slider 3 is provided with a dovetail groove. The vertical slider 13 and the horizontal slider 3 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. The cooperation of the dovetail slider and the dovetail groove enables the vertical slider 13 to move inside the horizontal slider 3, thereby moving the trajectory of the vertical slider 13.

[0018] The operation of the drive motor 6 enables the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 to rotate, thereby allowing the rectangular extrusion plate 9 to move inside the rectangular oil storage chamber 8. This allows the lubricating oil inside the rectangular oil storage chamber 8 to be injected into the outside of the vertical rotating column 5 through the transverse lubricating oil through hole 7. The mechanical extrusion oil supply by the rectangular extrusion plate 9 can achieve precise quantitative supply of lubricating oil, ensuring that the vertical rotating column 5 always receives adequate lubrication and avoiding the problems of excessive or insufficient lubrication in traditional lubrication methods. The amount of lubricating oil supplied is automatically matched with the moving speed of the small mobile tool holder 1 by controlling the drive motor 6 to adapt to the lubrication needs of the small mobile tool holder 1 under different working conditions.

[0019] Working principle: Lubricating oil is injected into the rectangular oil storage chamber 8 through the oil injection hole. The operation of the drive motor 6 causes the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 to rotate. This rotation causes the longitudinal connecting rod 12 to rotate within the transverse slider 3. The rotation of the first longitudinal threaded rod 10 and the second longitudinal threaded rod 11 causes the longitudinal slider 13 to move within the transverse slider 3. The movement of the longitudinal slider 13, via the inclined rotating column 14, causes the transverse sliding column 15 to move within the transverse slider 3, thereby causing the two rectangular extrusion plates 9 to move. The movement of the rectangular extrusion plates 9 compresses the lubricating oil inside the rectangular oil storage chamber 8. Through the oil injection hole, lubricating oil is injected into the rectangular oil storage chamber 8. The movement of the rectangular extrusion plates 9 causes the lubricating oil inside the rectangular oil storage chamber 8 to be injected into the outside of the vertical rotating column 5 through the transverse lubricating oil through hole 7, ensuring that the vertical rotating column 5 always receives adequate lubrication.
