Description

Technical Field

[0001] The utility model relates to the field of tool processing, in particular to a wear-resistant steel blade grinding device. Background Art

[0002] Wear-resistant steel knives are knives made of special steel with good wear resistance, hardness and sharpness. In the blade production process, grinding is a key step to ensure the sharpness and service life of the blade. The traditional manual grinding method is inefficient and unstable in quality, and cannot meet the needs of modern industrial production. The existing grinding equipment clamps the blade through a clamping component, and the grinding component grinds the blade surface. However, during the grinding process, the blade needs to be manually flipped, so the blade needs to be removed from the clamping component and then reinstalled, which increases the grinding time and leads to low grinding efficiency. Utility Model Content

[0003] In view of the problems raised in the above background technology, the utility model provides a wear-resistant steel blade grinding device which can grind both sides of the blade more conveniently and improve the blade grinding efficiency.

[0005] Furthermore, the grinding mechanism includes an electric slider, which is slidably connected to the slide rail, and a rotating block is rotatably connected to the electric slider. Two magnets are fixedly connected to the electric slider, and the two magnets are symmetrically arranged. Two iron rods are fixedly connected to the rotating block, and the two iron rods are symmetrically arranged. The magnets adsorb the iron rods, and a bracket is fixedly connected to the rotating block.

[0006] Furthermore, the grinding mechanism also includes a sliding frame, the sliding frame is fixedly connected to the bracket, the sliding frame is slidably connected to a sliding seat, a pressure spring is connected between the sliding seat and the sliding frame, the sliding seat is fixedly connected to a motor, and a grinding disc is fixedly connected to the motor output shaft.

[0007] Furthermore, the rotating mechanism includes an overrunning clutch, the overrunning clutch is fixedly connected to the rotating block, a column gear is fixedly connected to the overrunning clutch, a gear rod is fixedly connected to the slide rail, and the column gear meshes with the gear rod.

[0008] Furthermore, it also includes a push rod, which is fixedly connected to the sliding seat.

[0009] The beneficial effects are: 1. The motor output shaft rotates to drive the grinding disc to rotate, and the electric slider drives the motor and the grinding disc to move toward the direction close to the gear rod. During the movement, the grinding disc will contact the blade, and the grinding disc rotates to grind the blade.

[0010] 2. The electric slider continues to slide toward the gear rod, so that the column gear and the gear rod engage. The rotation of the column gear drives the overrunning clutch to rotate, and the overrunning clutch drives the rotating block to rotate, so that the magnet and the iron rod are disengaged. When the column gear rotates 180 degrees, the magnet adsorbs the iron rod again. The column gear rotates 180 degrees to make the motor and the grinding disc flip to the bottom of the blade. The electric slider continues to move in the opposite direction, and the grinding disc will contact the bottom surface of the blade to grind the bottom surface of the blade. In this way, it is more convenient to grind both sides of the blade, thereby improving the efficiency of blade grinding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1: A wear-resistant steel blade grinding device, such as Figure 1-Figure 7 As shown, it includes a base 1, a slide rail 2 is fixedly connected to the base 1, a placement rack 3 is fixedly connected to the base 1, a blade 31 is placed on the placement rack 3, a screw 4 is threadedly connected to the placement rack 3, a fixed block 5 is rotatably connected to the bottom of the screw 4, the fixed block 5 and the placement rack 3 are slidably connected, a grinding mechanism and a rotating mechanism are provided on the slide rail 2, the grinding mechanism is used to grind the blade 31, and the rotating mechanism is used to drive the grinding mechanism to grind the other side of the blade 31, so that both sides of the blade 31 can be polished more conveniently, thereby improving the grinding efficiency of the blade 31.

[0021] The grinding mechanism includes an electric slider 6, which is slidably connected to the slide rail 2. A rotating block 7 is rotatably connected to the electric slider 6. Two magnets 71 are fixedly connected to the electric slider 6, and the two magnets 71 are symmetrically arranged. Two iron rods 72 are fixedly connected to the rotating block 7, and the two iron rods 72 are symmetrically arranged. The magnets 71 adsorb the iron rods 72, and a bracket 8 is fixedly connected to the rotating block 7.

[0022] The grinding mechanism also includes a sliding frame 11, which is fixedly connected to the bracket 8, a sliding seat 12 is slidably connected to the sliding frame 11, a pressure spring 15 is connected between the sliding seat 12 and the sliding frame 11, a motor 13 is fixedly connected to the sliding seat 12, and a grinding disc 14 is fixedly connected to the output shaft of the motor 13.

[0023] At first, the magnet 71 attracts the iron rod 72, so that the rotating block 7 is limited, and the electric slider 6 is located at the end of the slide rail 2 away from the gear rod 17. When working, the operator places the blade 31 on the placement rack 3, and then rotates the screw 4. The screw 4 and the placement rack 3 are connected by threads, so that the screw 4 will drop. The descent of the screw 4 will squeeze the fixed block 5, and the fixed block 5 will slide down along the placement rack 3 and squeeze the blade 31. After the fixed block 5 limits the blade 31, the operator stops rotating the screw 4, and then the operator starts the electric slider 6 and the motor 13. The electric slider 6 moves in the direction close to the gear rod 17, and the output shaft of the motor 13 rotates to drive the grinding disc 14 to rotate. The movement of the electric slider 6 will drive the motor 13 and the grinding disc 14 to move in the direction close to the gear rod 17. During the movement, the grinding disc 1 4 will contact the blade 31, and the grinding disc 14 rotates to grind the blade 31. When the grinding disc 14 and the blade 31 are separated, the operator turns off the motor 13 and the electric slide 6, and the operator rotates the screw rod 4 in the opposite direction. The screw rod 4 rises along the placement rack 3. The rising of the screw 4 will drive the fixing block 5 to rise, and then the blade 31 is turned over. Then the screw 4 is rotated again to limit the blade 31. The operator starts the motor 13 and the electric slide 6 again, and the electric slide 6 moves in the opposite direction, so that the grinding disc 14 grinds the blade 31 again. This is repeated three times. After the grinding is completed, the operator rotates the screw rod 4 in the opposite direction. The screw 4 rises along the placement rack 3. The rising of the screw 4 will drive the fixing block 5 to rise, and the blade 31 is no longer limited. The operator removes the polished blade 31 to achieve the grinding of the blade 31.

[0024] Embodiment 2: Based on embodiment 1, Figure 2-Figure 7 As shown, the rotating mechanism includes an overrunning clutch 9, the overrunning clutch 9 is fixedly connected to the rotating block 7, the overrunning clutch 9 is fixedly connected to a column gear 10, the slide rail 2 is fixedly connected to a gear rod 17, the column gear 10 will mesh with the gear rod 17, the meshing of the column gear 10 and the gear rod 17 will rotate 180 degrees, so that the motor 13 and the grinding disc 14 are flipped to the bottom of the blade 31, so that the grinding disc 14 can more conveniently grind both sides of the blade 31, thereby improving the grinding efficiency of the blade 31.

[0025] The sliding seat 12 further includes a push rod 16 , which is fixedly connected to the sliding seat 12 .

[0026] After the grinding disc 14 and the blade 31 are disengaged, the electric slider 6 continues to slide toward the direction close to the gear rod 17, and the electric slider 6 drives the column gear 10 to move, so that the column gear 10 and the gear rod 17 are meshed, so that the column gear 10 rotates, and the rotation of the column gear 10 drives the overrunning clutch 9 to rotate, and the overrunning clutch 9 drives the rotating block 7 to rotate, and the rotating block 7 drives the iron rod 72 to rotate, so that the magnet 71 and the iron rod 72 are disengaged. When the column gear 10 rotates 180 degrees, the magnet 71 adsorbs the iron rod 72 again, and the column gear 10 rotates 180 degrees to make the motor 13 and the grinding disc 14 flip over to the bottom of the blade 31, and then the electric slider 6 moves in the opposite direction, and the electric slider 6 drives the column gear 10 to move in the opposite direction, and the column gear 10 meshes with the gear rod 17 again. The grinding wheel 14 is in contact with the bottom surface of the blade 31 to grind the bottom surface of the blade 31, and so on. In this way, both sides of the blade 31 can be grinded more conveniently, thereby improving the grinding efficiency of the blade 31. When the grinding wheel 14 moves in the direction close to the blade 31, the push rod 16 will first contact the blade 31, and the blade 31 squeezes the push rod 16 to make the sliding seat 12 rise, and the pressure spring 15 is compressed. The rising sliding seat 12 will lift the grinding wheel 14 to the same height as the surface of the blade 31. When the grinding wheel 14 and the blade 31 are separated, the pressure spring 15 drives the sliding seat 12 to reset, thereby automatically adjusting the grinding height of the grinding wheel 14 and further improving the grinding efficiency.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
