Description

Technical Field

[0001] This utility model belongs to the field of steel plate segmentation technology, specifically a steel plate segmentation device. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling and pressing it. Steel plates are flat and rectangular, and can be directly rolled or cut from wide steel strips. Steel plates need to be cut into steel plates of the required size using a cutting device.

[0003] Chinese patent CN215431830U discloses a steel plate dividing device for stainless steel water tank production. The device includes a support frame, with a rotating shaft rotatably connected inside the support frame via a limiting bearing. A motor is bolted to the front of the support frame, and the output end of the motor is bolted to the rotating shaft via a coupling. Several limiting sleeves are fitted onto the surface of the rotating shaft, and a saw blade is bolted to one side of each limiting sleeve. A groove is formed on the surface of the rotating shaft. This invention facilitates the movement of a stainless steel plate by placing it on a table and the top of a rotating roller, and then pushing the plate through the roller. Pulling the limiting sleeves causes the saw blade to move, while a slider slides within the groove. Finally, tightening the limiting bolts fixes the limiting sleeves, allowing the user to adjust the dividing width.

[0004] In the above technology, the stainless steel plate is limited and fixed by the limiting sleeve through the limiting bolt during the movement, which can limit the movement in the longitudinal direction. However, the stainless steel plate may not move to the same position, so it cannot limit the movement in the lateral direction. Therefore, it is convenient to cut the stainless steel plate longitudinally, but it is not convenient to cut it transversely.

[0005] Therefore, a steel plate splitting device is proposed to address the above problems. Utility Model Content

A limiting mechanism is provided on the conveyor belt. The limiting mechanism includes a limiting plate and two clamping plates. Two positive and negative threaded rods are rotatably connected to the frame via bearings. The two ends of the limiting plate are threadedly connected to the two positive and negative threaded rods.

Two crossbars are fixedly connected between the two fixing plates, and the clamping plates slide on the crossbars.

[0009] Preferably, two electric guide rails are fixedly connected to the top of the frame, and a sliding seat is slidably connected to the top of each electric guide rail.

[0012] Preferably, a horizontal plate is fixed between the inner sidewalls of the frame, and the top of the horizontal plate is in contact with the bottom surface of the conveyor belt.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a steel plate cutting device, which consists of positive and negative threaded rods, a rotating wheel, and a belt. The steel plate is conveyed forward by the conveyor belt. When the steel plate reaches the limiting plate, it stops moving and is positioned at a predetermined location for cutting. After cutting, a third motor is activated, which drives the connected positive and negative threaded rods to rotate. These rods then drive the rotating wheel, which in turn drives the belt.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-5 This utility model provides a steel plate cutting device, including a frame 1. A conveyor belt 11 is mounted on one end of the frame 1 via a rotating shaft, and multiple rollers 12 are mounted on the other end of the frame 1 via roller shafts. A limiting mechanism is provided on the conveyor belt 11. The limiting mechanism includes a limiting plate 31 and two clamping plates 3. Two positive and negative threaded rods 310 are rotatably connected to the frame 1 via bearings. The two ends of the limiting plate 31 are threadedly connected to the two positive and negative threaded rods 310. The bottom of each positive and negative threaded rod 310 extends to the bottom of the frame 1. Each frame 1 has a rotating wheel 36 fixedly connected to its bottom end, and a belt 37 is sleeved between the two rotating wheels 36; an L-shaped plate 38 is fixedly connected to the bottom of the frame 1, and a third motor 39 is fixedly connected to the bottom of the L-shaped plate 38, with the output shaft of the third motor 39 fixedly connected to the bottom of the positive and negative threaded rod 310; the clamping plates 3 are symmetrically and movably connected inside the limiting plate 31; a steel plate body 13 is provided on the conveyor belt 11, and the steel plate body 13 is located between the limiting plate 31 and the two clamping plates 3; a cutting blade 254 is provided above the steel plate body 13.

[0028] To address the issue of inconvenient transverse cutting due to the inability to limit the lateral direction, during operation, the limiting plate 31 is positioned on the conveyor belt 11. The steel plate body 13 is placed on the conveyor belt 11, and under its action, it is conveyed forward. When the steel plate reaches the limiting plate 31, it stops moving, limiting the steel plate body 13 to a specific position. At this point, by adjusting the two clamping plates 3, the steel plate body 13 is fixed between the two clamping plates 3 and the limiting plate 31, thus achieving lateral and longitudinal fixation of the steel plate body 13. The cutting blade 2 then... 54. After cutting, the third motor 39 needs to be turned on. The third motor 39 drives the connected positive and negative threaded rods 310 to rotate. The positive and negative threaded rods 310 drive the rotating wheel 36 to rotate. The rotating wheel 36 drives the belt 37 to rotate. The belt 37 drives another rotating wheel 36 to rotate. The rotating wheel 36 drives the connected positive and negative threaded rods 310 to rotate. The two positive and negative threaded rods 310 rotate at the same time, causing the limiting plate 31 to move upward. The limiting plate 31 moves upward stably and continues to transport the cut steel plate body 13 through the conveyor belt 11.

[0029] Furthermore, such as Figure 5 As shown, two fixing plates 32 are fixedly connected to the side wall of the limiting plate 31; a bidirectional ball screw 33 is rotatably connected to the two fixing plates 32 via bearings, and two clamping plates 3 are threadedly connected to the bidirectional ball screw 33. A second motor 35 is fixedly connected to one of the fixing plates 32, and the output shaft of the second motor 35 is fixedly connected to the bidirectional ball screw 33. Two crossbars 34 are fixedly connected between the two fixing plates 32, and the clamping plates 3 slide on the crossbars 34.

[0030] When it is necessary to limit and fix both sides of the steel plate body 13 during operation, the second motor 35 needs to be turned on. The output shaft of the second motor 35 drives the bidirectional ball screw 33 to rotate. Since there is a ball nut seat at the connection between the bidirectional ball screw 33 and the clamping plate 3, the radial movement of the clamping plate 3 is ensured by the ball nut seat. The bidirectional ball screw 33 drives the clamping plate 3 to move in the opposite direction. At the same time, the clamping plate 3 moves towards the steel plate body 13, thereby achieving the fixation and limitation of the steel plate body 13.

[0031] Furthermore, such as Figure 1 As shown, two electric guide rails 2 are fixedly connected to the top of the frame 1. Each electric guide rail 2 is slidably connected to a sliding seat 21. The top ends of the two sliding seats 21 are rotatably connected to a reciprocating screw 22 via bearings. A movable seat 25 is threadedly connected to the reciprocating screw 22. Two guide rods 23 are fixedly connected between the two sliding seats 21. The movable seat 25 is slidably connected to the guide rods 23. A first motor 24 is fixedly connected to one of the sliding seats 21. The output shaft of the first motor 24 is fixedly connected to one end of the reciprocating screw 22.

[0032] During operation, the cutting dimensions of the steel plate body 13 are set on the computer program. The computer program controls the electric guide rail 2 and the first motor 24. The electric guide rail 2 drives the cutting blade 254 to move longitudinally to cut the steel plate longitudinally. The first motor 24 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the moving seat 25 to move. The moving seat 25 drives the cutting blade 254 to move laterally to cut the steel plate laterally, thus achieving precise control of the position of the cutting blade 254.

[0033] Furthermore, such as Figure 4 As shown, a fixed frame 251 is fixedly connected to the bottom of the movable seat 25, an electric push rod 252 is fixedly connected inside the fixed frame 251, a drive mechanism 253 is fixedly connected to the output end of the electric push rod 252, and the cutting blade 254 is fixedly connected to the output end of the drive mechanism 253; both ends of the drive mechanism 253 are slidably connected to slide rods 255; springs 256 are sleeved on the outer side of each slide rod 255, and both ends of the springs 256 are fixedly connected to the fixed frame 251 and the drive mechanism 253 respectively.

[0034] During operation, the height of the cutting blade 254 is changed by activating the electric push rod 252, thereby enabling the cutting blade 254 to be extended and retracted and operated, and also satisfying the cutting of steel plate bodies 13 of different thicknesses; the direction of the cutting blade 254 is changed by the drive mechanism 253, thereby enabling the cutting of steel plate bodies 13 in different directions.

[0035] Furthermore, such as Figure 1 As shown, the rotating shaft of the conveyor belt 11 extends to the outside of the frame 1 and is fixedly connected to the first gear 4. The roller shaft of the drum 12 extends to the outside of the frame 1 and is fixedly connected to the second gear 42. The first gear 4 and the second gear 42 mesh. The bottom of the frame 1 is fixedly connected to the ash hopper 43, which is located below the drum 12.

[0036] During operation, when the conveyor belt 11 is conveying the cut steel plate body 13, it drives the first gear 4 to rotate through the rotating shaft, which in turn drives the second gear 42 to rotate. The second gear 42 then drives the roller shaft and drum 12 to rotate. When the cut steel plate body 13 is conveyed on the drum 12, the debris falls into the ash hopper 43 through the gap between the drums 12, thereby separating the debris from the steel plate body 13.

[0037] Furthermore, such as Figure 3 As shown, a horizontal plate 14 is fixed between the inner sidewalls of the frame 1, and the top of the horizontal plate 14 is in contact with the bottom surface of the conveyor belt 11.

[0038] During operation, the conveyor belt 11 is prone to downward dent when the cutting blade 254 cuts, which causes deviation in the cutting size. By setting the horizontal plate 14, the horizontal plate 14 lifts the conveyor belt 11 upward during cutting, thereby fixing the conveyor belt 11 and reducing the deviation in the cutting size.

[0039] Working principle: During operation, the limiting plate 31 is located on the conveyor belt 11. By placing the steel plate body 13 on the conveyor belt 11, the steel plate body 13 is conveyed forward under the action of the conveyor belt 11. When the steel plate moves to the limiting plate 31, it stops moving, limiting the steel plate body 13 to a certain position. The second motor 35 needs to be turned on, and the output shaft of the second motor 35 drives the bidirectional ball screw 33 to rotate. Since the connection between the bidirectional ball screw 33 and the clamping plate 3 is provided with a ball nut seat, the radial movement of the clamping plate 3 is ensured by the ball nut seat. The bidirectional ball screw 33 drives the clamping plate 3 to move in the opposite direction, and the clamping plate 3 moves towards the steel plate body. The directional movement of body 13 achieves the fixed positioning of the steel plate body 13; after cutting by the cutting blade 254, the third motor 39 needs to be turned on, which drives the connected positive and negative threaded rods 310 to rotate, which drives the rotating wheel 36 to rotate, which drives the belt 37 to rotate, which drives another rotating wheel 36 to rotate, which in turn drives the connected positive and negative threaded rods 310 to rotate; the two positive and negative threaded rods 310 rotate simultaneously, causing the limiting plate 31 to move upward, and the limiting plate 31 moves upward stably, and the cut steel plate body 13 continues to be transported by the conveyor belt 11;

[0040] During cutting, the cutting dimensions of the steel plate body 13 are set on the computer program. The computer program controls the electric guide rail 2 and the first motor 24. The electric guide rail 2 drives the cutting blade 254 to move longitudinally, cutting the steel plate longitudinally. The first motor 24 drives the reciprocating screw 22 to rotate, which in turn drives the moving seat 25 to move. The moving seat 25 then drives the cutting blade 254 to move laterally, cutting the steel plate laterally, thus achieving precise control of the position of the cutting blade 254. By activating the electric push rod 252, the height of the cutting blade 254 is changed, enabling the cutting blade 254 to be extended and retracted, and also accommodating the cutting of steel plates body 13 of different thicknesses. The direction of the cutting blade 254 is changed by the drive mechanism 253, enabling the cutting of the steel plate body 13 in different directions.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
