Description

Technical Field

[0001] This utility model relates to the field of steel processing, specifically a steel shearing machine with a pusher and anti-friction structure. Background Technology

[0002] Shearing machines are mainly used to cut metal sheets into the required size and shape. Chinese patent CN212144683U discloses a feeding device for a shearing machine, including a limiting frame. By rotating the handle, the worm gear drives the coil to rotate through the fixed shaft. Under the action of the coil, the clamping plates on both sides can move simultaneously towards the center on the limiting frame through the connecting lines on both sides, thus enabling convenient and quick limiting and fixing of sheets of different widths and sizes.

[0003] When the feeding device of the shearing machine mentioned above pushes the material for cutting, the plate will continuously rub against the support and contact positions of the shearing machine body. Long-term friction will cause scratches and unevenness at the friction positions, affecting the service life of the equipment and the cutting effect of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a steel shearing machine with a pushing and anti-friction structure. When the end of the plate is pushed towards the inside of the housing by the limiting frame, the lower end of the plate is supported by the first support wheel. The rotation of the first support wheel can prevent the plate from rubbing against the support plate. After the position is adjusted, the extension of the shim assists the first support wheel in supporting the cutting force and the pressing force of the pressing block. When the plate is pushed, the shim retracts into the second groove, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel shearing machine with a pushing and anti-friction structure, comprising a housing, a support plate provided on one side of the housing, a first groove provided inside the support plate, a second groove and a third groove sequentially provided on one side of the first groove, a limiting frame with a pair of fourth grooves provided on one side of the support plate, a first support wheel provided inside the first groove, a gasket provided inside the second groove, and a second support wheel provided inside both the fourth and third grooves, with hydraulic rods independently provided at the lower ends of the first support wheel, the gasket, and the second support wheel. When it is necessary to push the material toward the interior of the housing for subsequent cutting, the hydraulic rod pushes the first support wheel to extend, and the rotation of the first support wheel counteracts the friction. When the material is placed on the upper part of the limiting frame and the support plate, the second support wheel is pushed and extends, and the second support wheel counteracts the friction force when the material is moved laterally.

[0006] Preferably, the upper end of the outer side of the first support wheel protrudes from the upper end of the support plate, and the first support wheel that is pushed protrudes from the upper end of the support plate, so that the plate being cut and transported is supported by the support plate.

[0007] Preferably, the rolling direction of the first support wheel is the same as the direction in which the plate moves toward the inside of the housing and completes the cutting. The rotation of the first support wheel can counteract the frictional force when the material moves laterally toward the inside of the housing.

[0008] Preferably, the front and rear ends of the limiting frame are welded with sliding strips facing the housing. When the limiting frame moves laterally toward the housing, the sliding strips provide the trajectory for movement, and the lateral movement trajectory of the limiting frame is limited by restricting the sliding strips.

[0009] Preferably, the sliding bar is provided with a guide bar that is welded and fixed to the housing. The guide bar can restrict and guide the movement trajectory of the sliding bar.

[0010] Preferably, the sliding bar is embedded in the guide bar and slidably connected to the inside of the guide bar. When the limiting frame pushes the end of the plate toward the inside of the housing, the sliding bar slides outside the guide bar and pushes laterally stably, avoiding deviation when pushing a heavier plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, when placing the material to be cut, the second support wheel inside the third groove extends and contacts the lower end of the material. When the material is pushed from the side of the support plate and the limiting frame and placed on the upper end of the support plate and the limiting frame, the second support wheel, with the same directional force as the material being pushed, rotates inside the third groove to counteract friction. As the material is pushed towards the inside of the housing by the limiting frame and gradually cut, the gasket retracts inside the second groove, and the first support wheel independently contacts the material to be cut. When pushing the material, the rotation of the first support wheel can counteract the friction generated by the pushing. When placing and cutting the material, for sliding in different directions, the first support wheel inside the first groove and the third groove respectively contact the pushed material individually. The friction can be reduced by rotation, and damage to the material and steel shearing machine caused by friction can also be avoided. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1 As shown, the steel shearing machine with a pushing and anti-friction structure in this embodiment includes a housing 1. A support plate 6 is provided on one side of the housing 1. During the steel cutting process, the cutting is completed at the position of the support plate 6. Pressing blocks 2 are evenly distributed laterally at the upper end between the housing 1 and the support plate 6. After being driven, the pressing blocks 2 will move toward the support plate 6 and press the material at the upper end of the support plate 6, so that the cut material can be stably fixed at the upper end of the support plate 6.

[0021] After the material is pressed and cut by the pressing block 2, when it needs to continue moving towards the inside of the housing 1, in order to avoid friction during pushing, the support plate 6 is recessed with a first groove 3 corresponding to the position of the pressing block 2. A second groove 4 is provided on one side of the first groove 3. A first support wheel 13 is provided inside the first groove 3. The upper end of the first support wheel 13 protrudes from the upper end of the support plate 6. When pushing towards the inside of the housing 1, the rotation of the first support wheel 13 can offset the friction. The rolling direction of the first support wheel 13 is the same as the direction in which the material moves towards the inside of the housing 1 and completes the cutting.

[0022] To avoid the material being suspended over a large area when only the first support wheel 13 contacts the lower end of the material, a shim 14 is provided inside the second groove 4. When the material is not being pushed for position adjustment, the shim 14 extends out from inside the second groove 4 and contacts the lower end of the board together with the first support wheel 13 to support the board and bear the cutting and pressing forces of the pressing block 2. When the board is adjusted laterally, there is no pressing force on the upper end of the board, and the shim 14 retracts into the second groove 4, leaving only the first support wheel 13 to independently contact the upper end of the board during position adjustment.

[0023] To facilitate pushing the plate, a limit frame 7 is provided on one side of the support plate 6. Sliding strips 11 extend from both ends of the limit frame 7 towards the housing 1, and the sliding strips 11 are welded and fixed to the limit frame 7. Figure 2 As shown, guide bars 10 are provided on the outer side of the two sliding bars 11 facing the housing 1, and the guide bars 10 are welded and fixed to the front and rear ends of the housing 1. The outer side of the sliding bar 11 is embedded in the inside of the guide bar 10 and is laterally slidably connected to the inside of the guide bar 10. When the end of the plate is supported and pushed by the limiting frame 7, the sliding bar 11 will slide laterally along the guide bar 10 when the limiting frame 7 moves toward the housing 1. The sliding between the guide bar 10 and the sliding bar 11 can improve the stability during the sliding process and avoid positional deviation when the limiting frame 7 moves laterally.

[0024] Among them, a pair of first transmission wheels 8 are arranged horizontally at the lower end of the limiting frame 7. The first transmission wheels 8 support the upper limit frame 7 in contact with the equipment placement position, and the rotation of the first transmission wheels 8 can also prevent the limiting frame 7 from rubbing against the ground during the horizontal movement of the limiting frame 7.

[0025] In addition, in order to allow the slider 11 to slide laterally within the guide bar 10, such as Figure 4 As shown, the upper and lower ends of the sliding bar 11 embedded in the guide bar 10 are provided with second transmission wheels 16. The two second transmission wheels 16 protrude from the outside of the sliding bar 11 and are in contact with the guide bar 10. When the second transmission wheels 16 are driven to rotate by the motor, the second transmission wheels 16 will actively drive the sliding bar 11 and the connected limit frame 7 to move laterally.

[0026] To prevent the sheet material from sliding sideways and rubbing against the support plate 6 and the limiting frame 7, such as... Figure 3 As shown, a pair of third grooves 5 are provided on one side of the second groove 4, and a pair of fourth grooves 12 are provided inside the limiting frame 7. Both the fourth groove 12 and the third groove 5 are provided with second support wheels 15. The rotation direction of the second support wheels 15 is perpendicular to the rotation direction of the first support wheels 13. The second support wheels 15 can match the trajectory of the plate being slidably placed on the upper end of the limiting frame 7 and the support plate 6 from the side. The extension of the second support wheels 15 and the rotation of the second support wheels 15 when in contact with the plate can avoid damage to the friction position caused by the friction force.

[0027] In order to adjust the extension state of the first support wheel 13, the washer 14, and the second support wheel 15, such as... Figure 5As shown, the lower ends of the first support wheel 13, the pad 14, and the second support wheel 15 are each independently equipped with a hydraulic rod 17. The hydraulic rods 17 at the lower ends of the first support wheel 13, the pad 14, and the second support wheel 15 extend and retract accordingly, so that the equipment can adapt to the friction reduction when placing materials and the friction reduction when pushing materials to cut.

[0028] The position of the limiting frame 7 where the plate is placed is flush with the height of the first support wheel 13 and the shim 14 after they extend, so as to avoid the cutting position being tilted due to inconsistent heights during cutting.

[0029] Working principle: Before using the device, when placing the sheet steel, insert it laterally from the side of the limiting frame 7 and the support plate 6. Activate and extend the hydraulic rod 17 at the lower end of the second support wheel 15 inside the third groove 5 and the fourth groove 12, exposing the second support wheel 15. Activate and retract the hydraulic rod 17 at the lower end of the first support wheel 13 and the gasket 14 inside the first groove 3 and the second groove 4, laterally pushing the sheet steel in contact with the second support wheel 15, so that both ends of the steel are respectively positioned on the upper ends of the support plate 6 and the limiting frame 7. When using the device and pushing the sheet steel to be cut, the second support wheel 15 inside the third groove 5 and the fourth groove 12 is retracted into the device by the retraction of the hydraulic rod 17, and the first groove 3 and the second groove 4 are exposed outside the support plate 6 by the extension of the hydraulic rod 17. During cutting, the pressing block 2 presses the material vertically downwards. After pressing, the material is cut by contact with the blade. When the cutting is completed and the material needs to be pushed for further cutting, the pressing block 2 retracts and resets. The hydraulic rod 17 at the lower end of the pad 14 retracts, causing the pad 14 to retract into the second groove 4. The first support wheel 13 independently contacts the bottom of the plate. The motor corresponding to the second transmission wheel 16 inside the sliding bar 11 is activated. The rotation of the second transmission wheel 16 causes the sliding bar 11 to slide along the guide bar 10. The sliding of the sliding bar 11 drives the limit frame 7 to push the material to be cut. The cut steel will move towards the inside of the housing 1. During the movement, the exposed first support wheel 13 will be offset by rotation until the material moves laterally to the required distance. Then the pad 14 extends again and is pressed by the pressing block 2 to complete the repeated cutting action.
