Description

Technical Field

[0001] The utility model relates to the technical field of steel plate burr grinding, in particular to a steel plate processing burr grinding device. Background Art

[0002] Steel plate is a flat steel material that is cast by molten steel and pressed after cooling. It is flat and rectangular and can be directly rolled or cut from wide steel strip.

[0003] When processing steel plates, the cutting tool will wear out after long-term use. At the same time, too fast cutting speed will cause the metal on the cutting surface to generate too much heat, which will cause burrs on the processed steel plates. When it is necessary to grind the burrs on both sides of the steel plate, the staff puts the steel plate into the grinding device for grinding. After the steel plate comes out of the grinding device, the staff needs to clean up the debris generated after the steel plate is ground, and then turn the steel plate over and put it into the grinding device again to grind the other side of the steel plate. The staff manually takes, turns and places the steel plate, which is time-consuming and labor-intensive, and reduces the efficiency of grinding the burrs on the steel plate. Therefore, a burr grinding device for steel plate processing is proposed to solve the above problems. Utility Model Content

[0035] A mounting groove is provided at one end of the moving block 16, in which a round tube 1601 is rotatably connected, and teeth 1602 meshing with the half gear 903 are fixedly connected on the surface of the round tube 1601 (the rotation of the half gear 903 drives the teeth 1602 and the moving block 16 to move upward, thereby driving the top rod 1701 to move upward through the moving rod 17, so that the rotating plate 1101 rotates and drives the steel plate to flip), and a baffle 1603 fixedly connected to the mounting groove is arranged above the teeth 1602 (the baffle 1603 allows the teeth 1602 to rotate in only one direction), and a coil spring is connected to the round tube 1601 and one side of the storage groove (the coil spring can drive the teeth 1602 to reset).

[0036] A further advantage of adopting the above method is that the above device does not require the staff to manually pick up, flip and place the steel plates, and does not require the staff to clean up the debris generated when grinding the steel plates, which saves time and effort while improving the efficiency of grinding burrs on the steel plates.

[0037] The forward and reverse motor 14 is a prior art, and its model is KYDAS96300-1E. It can drive the rotating shaft 1401 to rotate, and will not be described in detail here.

[0038] When the utility model is used: when it is necessary to grind the burrs of the steel plate, the staff puts the steel plate into the placing box 6, and puts a steel plate on the conveyor belt 9 at the same time, and then the staff starts the forward and reverse motor 14, and the forward and reverse motor 14 drives the driving gear ring 1402 to rotate through the rotating shaft 1401, and drives the linkage gear ring 702 to rotate through the driving gear ring 1402, and the linkage gear ring 702 rotates to drive the belt teeth 12 and the conveying roller 901 to rotate, thereby driving the conveyor belt 9 to rotate to transport the steel plate;

[0039] At the same time, the rotating shaft 1401 drives the belt ring 1501 and the first grinding roller 1403 to rotate, and drives the second grinding roller 1502 to rotate through the belt ring 1501, so that the two grinding rollers rotate to grind the steel plate. When the steel plate is being grinded, the bottom end of the circular box 7 is in a fitting state with the steel plate, so that the debris generated when the steel plate is grinded can be scraped off and fall into the collecting box 13 through the discharge port;

[0040] After the grinding roller has finished grinding one side of the steel plate, the conveyor belt 9 will continue to transport the steel plate and transport it to the inclined plate 11, so that the steel plate slowly becomes an inclined state along the inclined plate 11. At this time, the forward and reverse motors 14 are controlled to reverse, so that the conveying rollers 901, the conveying belt 9 and the grinding rollers are reversed, and the conveying rollers 901 reversely drive the driving shaft 902 and the half gear 903 to reverse, thereby driving the teeth 1602, the moving block 16 and the moving rod 17 to move upward, and driving the top rod 1701 to move upward to drive the rotating plate 1101 to rotate, so as to flip the steel plate, so that the steel plate turns over and falls back onto the conveyor belt 9, and the steel plate continues to be transported, and the steel plate is transported to the grinding roller, so that the grinding roller grinds the burrs on the other side of the steel plate;

[0041] When both sides of the steel plate on the conveyor belt 9 are polished, the conveyor belt 9 conveys it to the L-shaped movable plate 5, and allows the steel plate to move inside the L-shaped movable plate 5 while pushing the L-shaped movable plate 5 to move. When the L-shaped movable plate 5 and the steel plate inside it move to the top of the collection box 4, the steel plate in the L-shaped movable plate 5 falls into the collection box 4. At this time, the steel plate in the placement box 6 falls onto the conveyor belt 9 (due to the obstruction of the L-shaped movable plate 5, the steel plate now on the conveyor belt 9 cannot move to the collection box 4 with the conveyor belt 9). The staff controls the forward and reversing motor 14 to rotate forward, and at the same time the spring coil drives the L-shaped movable plate 5 to reset, and pushes the steel plate on the conveyor belt 9, so that the steel plate moves along the conveyor belt 9 and moves to the grinding roller for grinding. The subsequent burr grinding process of the steel plate in the placement box 6 is as described above. The above-mentioned device does not require the staff to manually take, flip and place the steel plate. At the same time, the staff does not need to clean up the debris generated when the steel plate is ground, which saves time and effort while improving the efficiency of grinding the burrs of the steel plate.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
