[0002] Also known as an arch bending machine, it is a mechanical device specifically designed for bending steel. It is mainly used in tunnel, subway, hydropower station, and underground cavern projects to bend I-beams, channel steel, angle steel, U-shaped steel, and other profiles. Cold bending machines are widely used in the processing and fabrication of tunnel support steel arch frames, meeting the bending and deformation requirements of steel in various engineering construction projects.

[0003] In the prior art, such as the Chinese patent publication number CN219378573U, a slider adjustment mechanism for a cold bending machine includes a base, a mounting seat, a slider, and a lead screw. A support spring is provided between the slider and the mounting seat. Mounting blocks are fixedly mounted on both the mounting seat and the slider. The mounting blocks have insertion slots. Insert plates are fixedly mounted on both ends of the support spring. The insert plates are slidably mounted on the insertion slots. Fixing components for fixing the support spring are provided on the mounting blocks and the insert plates. The fixing components include a mounting opening on the side of the mounting block located at the insertion slot, a fixing spring disposed in the mounting opening, a fixing block slidably disposed on the mounting opening, and a fixing opening on the side of the insert plate. This slider adjustment mechanism for a cold bending machine enables easy disassembly and assembly of the support spring, facilitates the replacement of support springs with weakened elasticity, improves the stability of subsequent device operation, has a simple structure, saves time and effort, and is highly practical.

[0004] In actual production, although the slider adjustment mechanism of this type of cold bending machine can also adjust the slider, it requires workers to frequently rotate the screw to move the slider between the slider and the mounting base, which increases the labor intensity of workers and results in poor performance of the equipment. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a slider adjustment device for a cold bending machine, which has a good effect on slider adjustment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a slider adjustment device for a cold bending machine, comprising a conveying trough, a table leg fixedly connected to the bottom of the conveying trough, a support plate fixedly connected to the bottom of the table leg, a vertical plate provided on the outside of the conveying trough, a slotted hole opened inside the conveying trough, a push plate provided inside the conveying trough, the vertical plate penetrating into the slotted hole and fixedly connected to the push plate, a hydraulic press provided inside the conveying trough, the output end of the hydraulic press fixedly connected to the push plate, a stud provided on the outside of the conveying trough, one end of the stud fixedly connected to the vertical plate, a small hole opened inside the vertical plate, a base plate provided on the outside of the conveying trough, a rotating rod fixedly connected to the outside of the base plate, a motor base fixedly connected to the outside of the conveying trough, an adjustment hole opened inside the vertical plate, a round rod provided on the outside of the vertical plate, a cylindrical slider rotatably connected to the outside of the round rod, and the round rod penetrating into the adjustment hole.

[0007] By adopting the above technical solution, workers push steel plates into the conveying trough of the cold bending machine. When the steel plates are conveyed inside, their upper surface contacts the cylindrical slider, causing the slider to rotate. This makes the conveying of the steel plates smoother, and the force exerted by the cylindrical slider prevents the steel plates from shifting during conveying. When the size of the conveyed steel plate changes, the hydraulic press is started. The hydraulic press output drives the push plate to rise, which in turn raises the vertical plate and the cylindrical slider. This adjusts the gap between the cylindrical slider and the upper surface of the conveyed steel plate, preventing the steel plate from becoming too tall to pass through the bottom of the cylindrical slider after the size changes. This adjustment method does not require workers to frequently rotate the screw for adjustment, achieving excellent slider adjustment results.

[0008] A further feature of this invention is that a motor is fixedly connected to the upper surface of the motor base, the output end of the motor is fixedly connected to the base plate, and a brush is fixedly connected to the outside of the rotating rod.

[0009] By adopting the above technical solution, the motor is started, and the output end of the motor drives the base plate and rotating rod to rotate. The rotating brush cleans the upper surface of the steel plate it passes over.

[0010] A further feature of this invention is that a grinding disc is fixedly connected to the outside of the rotating rod, and the number of grinding discs is two.

[0011] By adopting the above technical solution, the rotation of the rotating rod causes the grinding disc to rotate, smoothing out the burrs on the surface of the steel plate it passes over.

[0012] A further feature of this invention is that a sliding ball is provided on the outside of the push plate, and the sliding ball is slidably connected to the inner wall of the conveying groove.

[0013] By adopting the above technical solution, the sliding connection between the sliding ball and the inner wall of the conveying trough facilitates the smooth movement of the push plate after being subjected to force.

[0014] A further feature of this invention is that a friction layer is fixedly connected to the upper surface of the cylindrical slider, and the thickness of the friction layer is three centimeters.

[0015] By adopting the above technical solution, the three-centimeter friction layer increases the friction between the upper surface of the steel plate and the cylindrical slider, preventing the cylindrical slider from slipping.

[0016] A further feature of this invention is that the upper surface of the vertical plate is provided with a scale, and the upper surface of the scale is provided with scale values.

[0017] By adopting the above technical solution, the scale value set on the upper surface of the dial indicator provides a reference for the distance the vertical plate is raised.

[0018] A further feature of this invention is that a torsion head is provided on the outside of the vertical plate, and the other end of the stud penetrates into the interior of the small hole and is fixedly connected to the torsion head.

[0019] By adopting the above technical solution, the distance between the two vertical plates is reduced by twisting the toggle head, thereby causing the two vertical plates to contact the rotating cylindrical slider, thus adjusting the rotation speed of the cylindrical slider.

[0020] A further feature of this invention is that the conveying trough is internally connected with rollers, and the distance between each pair of rollers is equal.

[0021] By adopting the above technical solution, the steel plate is facilitated to be transported inside the conveying trough through the action of rollers.

[0022] A further feature of this invention is that a placement plate is fixedly connected to the outside of the conveying trough, and the number of placement plates is two.

[0023] By adopting the above technical solution, the two placement plates facilitate the placement of the traction clamps.

[0024] A further feature of this invention is that the upper surface of the placement plate is provided with traction clamps, and the number of traction clamps is two.

[0025] By adopting the above technical solution, workers use traction pliers to pull out the bent steel plate.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a conveying trough, table legs, support plate, vertical plate, slot, push plate, hydraulic press, stud, small hole, cylindrical slider, bottom plate, adjusting hole, and round rod, allows workers to push steel plates into the conveying trough of a cold bending machine. During conveying, the upper surface of the steel plate contacts the cylindrical slider, causing it to rotate, thus ensuring smoother conveying. The force exerted by the cylindrical slider prevents the steel plate from shifting during transport. When the size of the conveyed steel plate changes, the hydraulic press is activated. The output of the hydraulic press drives the push plate, raising it, which in turn raises the vertical plate and the cylindrical slider. This adjusts the gap between the cylindrical slider and the upper surface of the conveyed steel plate, preventing the steel plate from becoming too tall to pass through the bottom of the cylindrical slider after a size change. This adjustment method eliminates the need for frequent screw rotation by workers, achieving excellent slider adjustment.

[0028] 2. This utility model, through the arrangement of a motor, brush, grinding disc, sliding ball, friction layer, scale, toggle head, roller, placement plate, and traction clamp, allows the motor to be started. The output end of the motor drives the base plate and rotating rod to rotate. The rotating brush cleans the surface of the steel plate it passes through. The rotation of the rotating rod drives the grinding disc to grind the burrs on the surface of the steel plate it passes through. The sliding connection between the sliding ball and the inner wall of the conveying trough facilitates the smooth movement of the push plate after being subjected to force. The three-centimeter friction layer increases the friction force generated by the contact between the upper surface of the steel plate and the cylindrical slider, preventing the cylindrical slider from slipping. The scale value set on the upper surface of the scale provides a reference for the height of the vertical plate. By twisting the toggle head, the distance between the two vertical plates is reduced, thereby allowing the two vertical plates to contact the rotating cylindrical slider, thus adjusting the rotation speed of the cylindrical slider. The action of the roller facilitates the conveying of the steel plate inside the conveying trough. The two placement plates facilitate the placement of the traction clamp, and the worker uses the traction clamp to pull out the bent steel plate. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments.

[0036] Reference Figure 1-4A slider adjustment device for a cold bending machine includes a conveying trough 1, a table leg 2 fixedly connected to the bottom of the conveying trough 1, a support plate 3 fixedly connected to the bottom of the table leg 2, a vertical plate 4 disposed on the outside of the conveying trough 1, a slotted hole 5 opened inside the conveying trough 1, a push plate 6 disposed inside the conveying trough 1, the vertical plate 4 penetrating into the slotted hole 5 and fixedly connected to the push plate 6, a hydraulic press 7 disposed inside the conveying trough 1, the output end of the hydraulic press 7 fixedly connected to the push plate 6, a stud 8 disposed on the outside of the conveying trough 1, one end of the stud 8 fixedly connected to the vertical plate 4, a small hole 9 opened inside the vertical plate 4, a base plate 11 disposed on the outside of the conveying trough 1, a rotating rod 12 fixedly connected to the outside of the base plate 11, a motor base 13 fixedly connected to the outside of the conveying trough 1, and the vertical plate 4... An adjustment hole 20 is provided inside the vertical plate 4. A round rod 21 is provided on the outside of the vertical plate 4. A cylindrical slider 10 is rotatably connected to the outside of the round rod 21. The round rod 21 passes through the interior of the adjustment hole 20. When the worker pushes the steel plate into the conveying trough 1 of the cold bending machine, the upper surface of the steel plate contacts the cylindrical slider 10, causing the cylindrical slider 10 to rotate, thus making the steel plate conveyed more smoothly. The force exerted by the cylindrical slider 10 on the steel plate prevents it from shifting during conveying. When the size of the conveyed steel plate changes, the hydraulic press 7 is started. The hydraulic press 7 starts working, and the output end of the hydraulic press 7 drives the push plate 6 to work, raising the push plate 6, which in turn raises the vertical plate 4 and the cylindrical slider 10, thereby adjusting the cylindrical slider 10 and the conveyed steel plate. The gap between the upper surface of the conveyor prevents the height of the conveyed steel plate from becoming too high after the size of the conveyor plate changes, thus preventing it from passing through the bottom of the cylindrical slider 10. This adjustment method does not require the operator to frequently rotate the screw for adjustment, achieving a better slider adjustment effect. A motor 14 is fixedly connected to the upper surface of the motor base 13, and the output end of the motor 14 is fixedly connected to the base plate 11. A brush 15 is fixedly connected to the outside of the rotating rod 12. When the motor 14 is started, the output end of the motor 14 drives the base plate 11 and the rotating rod 12 to rotate. The rotating brush 15 cleans the upper surface of the steel plate that passes through. Two grinding discs 16 are fixedly connected to the outside of the rotating rod 12. The rotation of the rotating rod 12 drives the grinding discs 16 to rotate, grinding the burrs on the upper surface of the steel plate that passes through. The push plate 6 is equipped with a sliding ball 17 on its exterior. The sliding ball 17 is slidably connected to the inner wall of the conveying trough 1. This slidable connection facilitates the smooth movement of the push plate 6 under force. A friction layer 18 with a thickness of three centimeters is fixedly connected to the upper surface of the cylindrical slider 10. This three-centimeter friction layer 18 increases the friction force generated by the contact between the upper surface of the steel plate and the cylindrical slider 10, preventing the cylindrical slider 10 from slipping. A scale 19 is provided on the upper surface of the vertical plate 4. The scale value on the upper surface of the scale 19 provides a reference for the distance the vertical plate 4 rises. A toggle head 22 is provided on the exterior of the vertical plate 4. The other end of the stud 8 passes through the small hole 9 and is fixedly connected to the toggle head 22.By twisting the toggle head 22, the distance between the two vertical plates 4 is reduced, causing the two vertical plates 4 to contact the rotating cylindrical slider 10, thereby adjusting the rotation speed of the cylindrical slider 10. Inside the conveying trough 1, rollers 23 are rotatably connected, with equal spacing between each pair of rollers 23. The rollers 23 facilitate the conveying of the steel plate inside the conveying trough 1. Two placement plates 24 are fixedly connected to the outside of the conveying trough 1. These two placement plates 24 facilitate the placement of the traction clamps 25. Two traction clamps 25 are installed on the upper surface of the placement plates 24. Workers use the traction clamps 25 to pull out the bent steel plate.

[0037] In this invention, the worker pushes the steel plate into the conveying trough 1 of the cold bending machine. As the steel plate is conveyed, its upper surface contacts the cylindrical slider 10, causing the slider 10 to rotate. This ensures smoother conveying of the steel plate. The force exerted by the cylindrical slider 10 prevents the steel plate from shifting during conveying. When the size of the conveyed steel plate changes, the hydraulic press 7 is started. The output of the hydraulic press 7 drives the push plate 6, raising it and consequently raising the vertical plate 4 and the cylindrical slider 10. This adjusts the gap between the cylindrical slider 10 and the upper surface of the conveyed steel plate, preventing the steel plate from becoming too tall to pass under the cylindrical slider 10 after a size change. This adjustment method eliminates the need for frequent screw rotation by the worker, achieving excellent slider adjustment. The motor 14 is then started, and its output drives the base plate 11. The rotating rod 12 rotates, and the rotating brush 15 cleans the surface of the steel plate it passes through. The rotation of the rotating rod 12 causes the grinding disc 16 to rotate, smoothing the burrs on the surface of the steel plate it passes through. The sliding connection between the ball 17 and the inner wall of the conveying trough 1 facilitates the smooth movement of the push plate 6 after being subjected to force. The three-centimeter friction layer 18 increases the friction generated by the contact between the upper surface of the steel plate and the cylindrical slider 10, preventing the cylindrical slider 10 from slipping. The scale value set on the upper surface of the scale 19 provides a reference for the distance the vertical plate 4 rises. By twisting the toggle head 22, the distance between the two vertical plates 4 is reduced, thereby making the two vertical plates 4 contact the rotating cylindrical slider 10 respectively, thus adjusting the rotation speed of the cylindrical slider 10. Through the action of the roller 23, the steel plate is easily conveyed inside the conveying trough 1. The two placement plates 24 facilitate the placement of the traction clamp 25. The worker uses the traction clamp 25 to pull out the bent steel plate.
