Description

Technical Field

[0001] This utility model relates to the field of metal sheet metal mold processing technology, and in particular to a leveling device for metal sheet metal mold processing. Background Technology

[0002] The leveling device for metal sheet metal mold processing applies pressure through upper and lower roller systems or pressure plates. Utilizing the elastic-plastic deformation of metal and the Bauschinger effect, it eliminates the internal stress generated during sheet rolling and cutting, corrects deformations such as wavy edges and arches, ensures the flatness of the sheet metal, avoids scratches in subsequent processing, reduces equipment wear, and provides qualified blanks for welding, painting and other processes. It is a key piece of equipment for improving the quality of sheet metal processing.

[0003] Before entering the leveling process, sheet metal materials undergo pre-treatment processes such as cutting, stamping, and transportation. Metal shavings, oxide scale, dust, and other impurities easily adhere to their surfaces. If these residues are not cleaned in advance, they will enter the working roller system or pressure plate area with the sheet metal during the leveling process. This will not only aggravate roller wear and scratch the mold surface, but also cause defects such as indentations and pits on the leveled sheet metal.

[0004] Therefore, in order to address the existing problem of difficulty in collecting debris from the material surface, a leveling device for metal sheet metal mold processing is needed to solve the above problem. Utility Model Content

[0032] Specifically, a controller is installed at the front end of the base 1. The controller is electrically connected to the linear motor 2, hydraulic rod 4, electric push rod 9, vacuum pump 12, and hydraulic rod 14. The controller can synchronously drive the electric push rods 9 on both sides to extend and retract synchronously. A filter screen is installed inside the vacuum pump 12 to prevent debris from affecting the internal structure of the vacuum pump 12. By placing the material in the movable frame 3 and clamping it, and collecting the debris on the surface before leveling, it is possible to prevent debris from embedding into the material or scratching the equipment during processing, reduce roller wear and plate indentation defects, reduce subsequent cleaning costs, provide clean blanks for the leveling process, and improve the overall processing accuracy and efficiency.

[0033] refer to Figures 4-6 As shown in Embodiment 2: A hydraulic rod 14 is fixedly connected to the top of the fixed frame 8, and a movable frame 15 is fixedly connected to the bottom of the hydraulic rod 14. Rotating frames 16 are rotatably connected to both sides of the inner wall of the movable frame 15. The front and rear ends of the leveling roller 20 are provided with slots 21. The inner wall of each slot 21 is provided with a locking block 19. The outer wall of each locking block 19 is slidably connected to the inner wall of the rotating frame 16. The shape of the locking block 19 fits the slot 21. A pull rod 17 is slidably connected to the inner wall of the rotating frame 16. A rotating rod 18 is rotatably connected to the inner wall of each pull rod 17. The other end of each rotating rod 18 is rotatably connected to the inner wall of the locking block 19. Bolts are provided on the inner wall of each pull rod 17. Threaded grooves are provided on the inner wall of each rotating frame 16. The outer wall of each bolt is located on the inner wall of the threaded groove for disassembly and assembly of the leveling roller 20.

[0034] Specifically, when installing the leveling roller 20, first insert the leveling roller 20 into the rotating frame 16, and push the pull rod 17 upward to insert the locking blocks 19 on both sides into the locking slots 21. Then, rotate the bolt in the opposite direction to rotate the bolt into the threaded groove to limit the pull rod 17, thus completing the installation. By pulling the pull rod 17 downward, the leveling roller 20 can be removed, simplifying the roller disassembly process. No complicated tools are required, shortening the equipment maintenance and replacement time, facilitating the timely removal of residual debris on the surface of the leveling roller 20 or replacement of worn parts, improving equipment maintenance efficiency, and ensuring the accuracy and stability of subsequent leveling processing.

[0035] Working principle: First, the material is placed in the movable frame 3, and the hydraulic rod 4 is activated by the controller. The hydraulic rod 4 drives the front clamping plate 5 to move, and simultaneously drives the lower toothed plate 7 to move. Through the meshing gear 6, the rear toothed plate 7 and clamping plate 5 are moved to clamp and fix the material on both sides. After fixing, the linear motor 2 drives the movable frame 3 and the material to be conveyed to the right. The material is first conveyed to the lower side of the negative suction head frame 10, and through the electric push rods 9 on both sides, the negative suction head frame 10 is moved downwards, so that it is close to the bottom of the negative suction head frame 10. The material is brought close to the air pump 12 to generate negative pressure, which is then delivered to the negative suction head frame 10 through the folded tube 11. This negative pressure absorbs the debris on the outer wall of the material and delivers it to the collection box 13. After absorption, the material is delivered to the underside of the leveling roller 20. The hydraulic rod 14 drives the movable frame 15 and the leveling roller 20 to move downwards, pressing and leveling the material. After leveling, the product is delivered to the right, the clamp is released, the product is taken out, and the collection box 13 is removed for processing of the collected debris.

[0036] When it is necessary to remove the leveling roller 20, first turn the bolt to remove it from the threaded groove, release the limit on the pull rod 17, and then pull the pull rod 17 downward. The pull rod 17 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the two side locking blocks 19 to slide outward. Remove the locking blocks 19 from the locking groove 21, and then remove the leveling roller 20 downward to complete the disassembly.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
