Description

Technical Field

[0001] This utility model relates to a protective structure for a leveling machine, belonging to the field of leveling machine protection technology. Background Technology

[0002] As a core piece of equipment in the field of sheet metal processing, leveling machines are widely used in industries such as automobile manufacturing, aerospace, and building materials. They use multiple sets of rollers to roll and flatten sheet metal, eliminating defects such as waviness and bending. However, leveling machines pose numerous safety hazards during operation. For example, during equipment debugging, sheet feeding, cleaning, and maintenance, operators are prone to accidents where their hands or clothing can get caught in the rollers due to rotation, abnormal vibration, or loose parts, resulting in serious mechanical injuries.

[0003] Currently, most leveling machines on the market have simple, fixed protective covers. While these covers can isolate operators from hazardous parts to some extent, they have significant limitations:

[0004] On the one hand, when the equipment is being repaired or the plates are being loaded and unloaded, the protective cover needs to be disassembled or opened frequently. However, due to the lack of a mandatory locking mechanism, workers often disassemble and discard the protective structure without authorization because they find it troublesome, which renders the protective function ineffective and greatly reduces the actual protective effect, thus making the protective structure less effective.

[0005] On the other hand, during the leveling process, the plate is prone to displacement due to the vibration of the conveyor rollers, which requires manual adjustment by the staff. However, the existing protective structure can only play an isolation role and cannot assist in the automatic calibration of the plate, which increases the operational burden and causes inconvenience to the staff. As a result, the protective structure is not convenient to use. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0025] This utility model embodiment provides a protective structure for a leveling machine.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a leveling machine body 1, which is a small 15-roller leveling machine. Through multiple continuous rolling presses with small deformations, it can effectively eliminate defects such as wavy bends, central warping, and side wavy edges of the sheet material. Supports 2 are fixed at the four corners of the lower end of the leveling machine body 1. Slide grooves 3 are provided on both sides of the leveling machine body 1, and stabilizing grooves 4 are provided at the four corners of the lower side of the leveling machine body 1. Connecting structures are provided on the inner walls of the four stabilizing grooves 4. The connecting structures include two foot pedals 5, each foot pedal 5 having a drive frame 6 rotatably connected to both ends, and a slider 7 rotatably connected to the other end of each drive frame 6. A connecting frame 8 is rotatably connected to the middle of each slider 7. Fixing blocks 9 are rotatably connected to the upper ends of the two connecting frames 8, and protective covers 10 are fixed to the upper ends of the two fixing blocks 9. The protective covers 10 are made of honeycomb composite carbon fiber material, with a high-strength carbon fiber woven layer as the backbone. The frame is filled with aerospace-grade aluminum honeycomb core material, which is hot-pressed and cured. The carbon fiber layer gives it excellent tensile strength, while the aluminum honeycomb core constructs a stable support structure with a very small mass, about one-quarter the mass of a traditional steel protective cover 10, which greatly reduces the load on the equipment. Despite its light weight, the protective cover 10 can still ensure sufficient self-weight to achieve automatic reset through optimized design: its honeycomb structure effectively expands the force-bearing area without adding too much weight. Combined with the precisely calculated center of gravity distribution, it ensures that a stable vertical reset force can be generated when falling. At the same time, the high rigidity of carbon fiber prevents the protective cover 10 from deforming during the reset process, ensuring that each closure is accurate. It takes into account the requirements of lightweighting and realizes the forced reset function, improving the safety and ease of operation of the leveling machine. A through slot 11 is opened in the middle of the protective cover 10.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surface of the foot pedal 5 is slidably connected to the inner wall of two of the stabilizing grooves 4, the inner wall of the two foot pedals 5 is slidably connected to the outer surfaces of both sides of the leveling machine body 1, the two ends of the two foot pedals 5 are rotatably connected to the disjoint ends of four of the driving frames 6, the near ends of the four driving frames 6 are rotatably connected to one side of four sliders 7, the outer surface of two of the sliders 7 is slidably connected to the inner walls of both sides of one of the sliding grooves 3, the middle of the four sliders 7 is rotatably connected to the lower end of four connecting frames 8, the upper ends of two of the connecting frames 8 are rotatably connected to the lower end of one of the fixing blocks 9, the upper ends of the two fixing blocks 9 are fixed to both sides of the protective cover 10, the through groove 11 passes through the middle of the protective cover 10, and the outer surface of the leveling machine body 1 is slidably connected to the inner wall of the through groove 11.

[0028] In use, this invention works as follows: when a worker steps on the foot pedal 5, it moves vertically downwards due to the limiting constraint of the stabilizing groove 4. The two ends of the foot pedal 5 are rotatably connected to the drive frame 6, which drives two sliders 7 to slide synchronously within the limiting track on the inner wall of the corresponding slide groove 3. As the sliders 7 slide, the two connecting frames 8 rotatably connected to them are linked, pushing the two fixed blocks 9 upwards.

[0029] At this time, the protective cover 10, connected to the upper end of the fixed block 9, moves smoothly upward due to the limiting cooperation between the central through slot 11 and the leveling machine body 1. After moving upward, the protective cover 10 exposes the conveyor roller working area of ​​the leveling machine body 1, making it convenient for workers to place the material. After the material is unloaded, the worker releases the foot pedal 5, and the protective cover 10 falls vertically back to its original position under its own gravity. Through the reverse transmission of the connecting frame 8 and the drive frame 6, the foot pedal 5 is driven back to its initial position. This closed-loop mechanical linkage design achieves the effect of forced opening and closing of the protective cover 10, preventing workers from disassembling it without authorization, thereby improving the effectiveness of the protective structure. Example

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a central limiting function has been added;

[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that each of the four corners of the protective cover 10 is fixed with a connecting block 12. The four connecting blocks 12 are rotatably connected to a connecting frame 13 at their near ends. The other ends of the four connecting frames 13 are rotatably connected to a sliding frame 14. The near ends of the four sliding frames 14 are fixed with a limit frame 15. The two ends of the leveling machine body 1 are provided with limit grooves 16. The far ends of the four connecting blocks 12 are fixed to the inner walls of adjacent corners at both ends of the protective cover 10. The near ends of the four connecting blocks 12 are rotatably connected to the upper ends of the four connecting frames 13. The lower ends of the four connecting frames 13 are rotatably connected to the upper ends of the four sliding frames 14. The outer surfaces of two sliding frames 14 are slidably connected to the inner walls on both sides of one of the limit grooves 16. The vertical cross-section of the four sliding frames 14 is L-shaped. The near ends of the four sliding frames 14 are fixed to the far ends of the four limit frames 15. The four limit frames 15 are in clearance fit with the conveying rollers of the leveling machine body 1.

[0032] In use, this invention works as follows: when a worker steps on the foot pedal 5, it moves vertically downward under the limiting action of the stabilizing groove 4. The foot pedal 5, through the drive frame 6 rotatably connected at both ends, drives two sliders 7 to slide within the limiting tracks on the inner walls of the two sliding grooves 3. The sliders 7, through the two connecting frames 8 rotatably connected in the middle, push the two fixed blocks 9 upward, thereby causing the protective cover 10, which is fixedly connected to the upper end of the fixed blocks 9, to move upward smoothly. At the same time, the four connecting blocks 12, which are fixedly connected to the protective cover 10, rise synchronously. Two of the connecting blocks 12, through the two connecting frames 13, drive the two sliding frames 14 respectively, which, under the guidance and constraint of the limiting groove 16, move away from each other in the horizontal direction, thus making room for the loading of the sheet material.

[0033] After the worker places the sheet material on the conveyor roller of the leveling machine body 1, they release the foot pedal 5, and the protective cover 10 falls vertically to its original position under gravity. During the descent, the two connecting blocks 12 fixed to the protective cover 10 pull the two sliding frames 14 in opposite directions within the limiting groove 16 via the two connecting frames 13, bringing the two sliding frames 14 closer together. The two sliding frames 14 drive the two limiting frames 15 fixed on one side, applying a horizontal thrust to the sheet material on the conveyor roller, automatically adjusting the sheet material to the middle of the conveyor roller, achieving the effect of middle limiting. This eliminates the need for manual adjustment by the worker, bringing convenience to the operator and thus improving the ease of use of the protective structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
