Description

Technical Field

[0001] This utility model relates to the technical field of shearing mechanisms, and in particular to a shearing mechanism for shearing steel coils. Background Technology

[0002] Steel coils need to be sheared during processing to form individual steel plates. Shearing requires a shearing machine, and the key mechanism of the shearing machine is the shearing mechanism. Existing Chinese utility model patent CN219787350U discloses a bending, straightening, and shearing integrated machine for processing stainless steel coils. This machine discloses a shearing mechanism including a base plate. The base plate has a fixed support frame, a processing panel at its bottom, and an mounting plate above the processing panel. A cylinder is fixedly connected to the upper end of the support frame to push the mounting plate up and down. A cutter is fixed to the lower end of the mounting plate with screws. A groove is provided on the upper surface of the processing panel, directly below the cutter. During shearing, the stainless steel coil is stretched and enters the processing panel. The cylinder drives the mounting plate to descend, and as the mounting plate descends, the cutter descends synchronously to shear the stainless steel coil on the processing panel to form stainless steel plates.

[0003] However, the above-mentioned shearing mechanism uses a single cutter. When the single cutter cuts the steel plate, the two sides of the steel plate are subjected to unbalanced forces. Moreover, there is no limiting and clamping structure for the steel plate on both sides of the cutter, so the steel plate is prone to deflection during shearing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steel coil shearing mechanism that can simultaneously shear both sides of a steel plate, balance the force on the steel plate, avoid deviation during shearing, and improve stability.

[0005] This utility model discloses a shearing mechanism for steel coil shearing, including a frame; it also includes a first cutter shaft, a first bearing, a lower roller, a lower cutter, a second cutter shaft, a second bearing, an upper roller, and an upper cutter. The first cutter shaft is rotatably mounted on the frame. The inner ring of the first bearing is fitted onto the first cutter shaft, and the lower roller is fitted onto the outer ring of the first bearing. The two ends of the lower cutter are respectively connected to the two ends of the first cutter shaft, and the middle part of the lower cutter is located on the outer wall of the lower roller. The second cutter shaft is rotatably mounted on the frame, located above the first cutter shaft. The inner ring of the second bearing is fitted onto the second cutter shaft, and the upper roller is fitted onto the outer ring of the second bearing. A gap is provided between the upper roller and the lower roller for the steel plate to pass through. The two ends of the upper cutter are respectively connected to the two ends of the second cutter shaft, and the middle part of the upper cutter is located on the outer wall of the upper roller. The upper cutter and the lower cutter... The steel plates are symmetrically arranged vertically, with cutter shafts 1 and 2 rotating synchronously relative to each other. During operation, the end of the steel coil is pulled out and conveyed backward through the gap between the lower and upper rollers. When the steel plate is being conveyed, bearings 1 and 2 allow the lower and upper rollers to rotate relative to cutter shafts 1 and 2. When the steel plate extends a certain length, the operation pauses, and cutter shafts 1 and 2 are driven to rotate synchronously relative to each other. This causes cutter shaft 1 to drive the lower cutter and cutter shaft 2 to drive the upper cutter to rotate synchronously relative to each other. This brings the middle parts of the lower and upper cutters closer together, allowing for synchronous shearing of both sides of the steel plate. This makes the force on both sides of the steel plate more balanced. At the same time as shearing, the lower and upper rollers limit and clamp the steel plate on both sides of the lower and upper cutters to prevent the steel plate from shifting during shearing and improve the stability of the shearing process.

[0006] Preferably, the assembly also includes gear one, gear two, a drive motor, and a transmission assembly. Gear one is concentrically mounted on cutter shaft two, and gear two is concentrically mounted on cutter shaft one. Gear two meshes with gear one. The drive motor is mounted on the frame and is connected to cutter shaft one via the transmission assembly. The drive motor drives cutter shaft one to rotate via the transmission assembly. Cutter shaft one drives gear two to rotate. Gear two meshes with gear one and drives cutter shaft two to rotate, so that cutter shaft one and cutter shaft two can rotate synchronously relative to each other, and the lower cutter and upper cutter can rotate synchronously relative to each other, thus achieving synchronous driving of the lower cutter and upper cutter.

[0007] Preferably, it also includes a front support plate, two slides, and multiple limiting wheels. The front support plate is mounted on the frame and is located in front of the cutter shaft. The two slides are mounted on the front support plate, and multiple limiting wheels are rotatably mounted on each of the two slides. The multiple limiting wheels are arranged in two rows to roll and limit the two sides of the steel plate. The steel plate drawn out from the steel coil is laid flat on the front support plate, and the multiple limiting wheels roll and limit the left and right edges of the steel plate respectively. The steel plate, which is rolled and limited by the multiple limiting wheels, passes through the gap between the lower roller and the upper roller, making the steel plate conveying more stable.

[0008] Preferably, it also includes two slide rails, a double-threaded screw, and a servo motor. The two slide rails are installed on the lower part of the front support plate, and the two slide tables are slidably connected to the two slide rails respectively. The double-threaded screw is rotatably installed on the front support plate. The two slide rails and the double-threaded screw are arranged in parallel. The left and right parts of the double-threaded screw are respectively connected to the two slide tables through screw nuts. The servo motor is installed on the front support plate, and the output shaft of the servo motor is connected to the double-threaded screw. The servo motor drives the double-threaded screw to rotate, and the left and right parts of the double-threaded screw drive the two slide tables to move synchronously closer or further away along the two slide rails through the two screw nuts, thereby adjusting the spacing of multiple limit wheels to adapt to steel coils of different widths and providing good versatility.

[0009] Preferably, it also includes a rear support plate, which is mounted on the frame and located behind the cutter shaft. The rear support plate is used to support the steel plate. The steel plate passing through the lower roller and the upper roller is supported by the rear support plate. The steel plate after being cut by the lower cutter and the upper cutter is supported by the rear support plate and guided backward, thereby improving the output efficiency of the steel plate.

[0010] Preferably, the assembly also includes two drive wheels, two drive wheels, two drive belts, a cross baffle, and two side baffles. The two drive wheels are rotatably mounted on the front of the rear support plate, and the two drive wheels are rotatably mounted on the rear of the rear support plate. The front ends of the two drive belts are respectively fitted onto the two drive wheels, and the rear ends of the two drive belts are respectively fitted onto the two drive wheels. The two ends of the cross baffle are connected to the two drive belts, and the cross baffle is used to limit and block the end of the steel plate. The two side baffles are mounted opposite each other on the cross baffle, and the two side baffles are used to limit the two side edges of the end of the steel plate. The two drive wheels rotatably support the two drive belts. The end of the steel plate passes through the gap between the lower roller and the upper roller and is conveyed to the rear support plate. The end of the steel plate abuts against the cross baffle, and the two side baffles limit the two side edges of the steel plate. The end of the steel plate pushes the cross baffle backward, causing the two drive belts to rotate. The shearing length of the steel plate is measured by measuring the movement distance of the cross baffle, thus improving the accuracy of steel plate shearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, after the end of the steel coil is pulled out, it passes through the gap between the lower roller and the upper roller and is conveyed backward. When the steel plate is conveyed, the lower roller and the upper roller can rotate relative to the cutter shaft 1 and the cutter shaft 2 through bearing 1 and bearing 2. When the steel plate extends a certain length, it stops and drives the cutter shaft 1 and the cutter shaft 2 to rotate synchronously relative to each other. This causes the cutter shaft 1 to drive the lower cutter and the cutter shaft 2 to drive the upper cutter to rotate synchronously relative to each other. This makes the middle parts of the lower cutter and the middle parts of the upper cutter relatively close to each other and simultaneously shear the two sides of the steel plate, making the two sides of the steel plate more balanced. At the same time as shearing, the lower roller and the upper roller limit and clamp the steel plate on both sides of the lower cutter and the upper cutter, preventing the steel plate from shifting during shearing and improving the stability of shearing.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 5As shown, a shearing mechanism for steel coil shearing includes a frame 1; it also includes a first cutter shaft 2, a first bearing 3, a lower roller 4, a lower cutter 5, a second cutter shaft 6, a second bearing 7, an upper roller 8, and an upper cutter 9. The first cutter shaft 2 is rotatably mounted on the frame 1. The inner ring of the first bearing 3 is fitted onto the first cutter shaft 2. The lower roller 4 is fitted onto the outer ring of the first bearing 3. The two ends of the lower cutter 5 are respectively connected to the two ends of the first cutter shaft 2. The middle part of the lower cutter 5 is located on the outer wall of the lower roller 4. The second cutter shaft 6 is rotatably mounted on the frame 1. The second cutter shaft 6 is located above the first cutter shaft 2. The inner ring of the second bearing 7 is fitted onto the second cutter shaft 6. The upper roller 8 is fitted onto the outer ring of the second bearing 7. The upper roller 8 and the lower roller 4 are provided with a gap for the steel plate to pass through. The two ends of the upper cutter 9 are respectively connected to the two ends of the cutter shaft 6. The middle part of the upper cutter 9 is located on the outer wall of the upper roller 8. The upper cutter 9 and the lower cutter 5 are arranged symmetrically above and below. The cutter shaft 1 2 and the cutter shaft 2 6 rotate synchronously relative to each other. It also includes a gear 1 10, a gear 2 11, a drive motor 12 and a transmission assembly 13. The gear 1 10 is concentrically mounted on the cutter shaft 2 6, and the gear 2 11 is concentrically mounted on the cutter shaft 2. The gear 2 11 meshes with the gear 1 10. The drive motor 12 is mounted on the frame 1 and is connected to the cutter shaft 2 through the transmission assembly 13.

[0022] During operation, the end of the steel coil is pulled out and conveyed backward through the gap between the lower roller 4 and the upper roller 8. When the steel plate is conveyed, the lower roller 4 and the upper roller 8 can rotate relative to the cutter shaft 2 and the cutter shaft 6 through the bearing 3 and the bearing 7. When the steel plate extends a certain length, the operation stops. The drive motor 12 drives the cutter shaft 2 to rotate through the transmission assembly 13. The cutter shaft 2 drives the gear 11 to rotate. The gear 11 meshes with the gear 10 to drive the cutter shaft 6 to rotate, so that the cutter shaft 2 and the cutter shaft 6 can rotate synchronously relative to each other. This allows the cutter shaft 2 to drive the lower cutter 5 and the cutter shaft 2 to drive the upper cutter 9 to rotate synchronously relative to each other. This makes the middle of the lower cutter 5 and the middle of the upper cutter 9 relatively close to each other and synchronously shear the two sides of the steel plate, making the force on the two sides of the steel plate more balanced. At the same time as shearing, the lower roller 4 and the upper roller 8 limit and clamp the steel plate on both sides of the lower cutter 5 and the upper cutter 9 to prevent the steel plate from shifting during shearing and improve the stability of shearing. Example 2

[0023] like Figure 1 , Figure 2 and Figure 6As shown, based on Embodiment 1, it also includes a front support plate 14, two slides 15, and multiple limiting wheels 16. The front support plate 14 is mounted on the frame 1 and is located in front of the cutter shaft 2. The two slides 15 are mounted on the front support plate 14, and multiple limiting wheels 16 are rotatably mounted on each of the two slides 15. The multiple limiting wheels 16 are arranged in two rows to roll and limit the two sides of the steel plate. It also includes two slide rails 17, a double threaded screw 18, and a servo motor 19. The two slide rails 17 are mounted on the lower part of the front support plate 14, and the two slides 15 are slidably connected to the two slide rails 17 respectively. The double threaded screw 18 is rotatably mounted on the front support plate 14. The two slide rails 17 and the double threaded screw 18 are arranged in parallel. The left and right parts of the double threaded screw 18 are respectively connected to the two slides 15 through screw nuts. The servo motor 19 is mounted on the front support plate 14, and the output shaft of the servo motor 19 is connected to the double threaded screw 18.

[0024] Servo motor 19 drives double threaded screw 18 to rotate. The left and right sides of double threaded screw 18 drive two slide tables 15 to move synchronously closer or further away along two slide rails 17 through two screw nuts, thereby adjusting the spacing of multiple limit wheels 16 to adapt to steel coils of different widths. The steel plate extracted from the steel coil is laid flat on the front support plate 14. Multiple limit wheels 16 roll and limit the left and right edges of the steel plate respectively. The steel plate that has been limited by multiple limit wheels 16 passes through the gap between the lower roller 4 and the upper roller 8, making the steel plate conveying more stable. Example 3

[0025] like Figure 1 , Figure 2 and Figure 7 As shown, based on Embodiment 1, it also includes a rear support plate 20, which is mounted on the frame 1 and located behind the cutter shaft 2. The rear support plate 20 is used to support the steel plate. It also includes two drive wheels 21, two drive wheels 22, two drive belts 23, a horizontal baffle 24, and two side baffles 25. The two drive wheels 21 are rotatably mounted on the front of the rear support plate 20, and the two drive wheels 22 are rotatably mounted on the rear of the rear support plate 20. The front ends of the two drive belts 23 are respectively fitted onto the two drive wheels 21, and the rear ends of the two drive belts 23 are respectively fitted onto the two drive wheels 22. The two ends of the horizontal baffle 24 are respectively connected to the two drive belts 23. The horizontal baffle 24 is used to limit and block the end of the steel plate. The two side baffles 25 are mounted opposite each other on the horizontal baffle 24. The two side baffles 25 are used to limit the two side edges of the end of the steel plate.

[0026] Two drive wheels 21 and 22 rotate to support two drive belts 23. The steel plate passing through the lower roller 4 and the upper roller 8 is supported by the rear support plate 20. After being sheared by the lower cutter 5 and the upper cutter 9, the steel plate is supported by the rear support plate 20 and guided backward. The end of the steel plate abuts against the horizontal baffle 24. The two side baffles 25 limit the two side edges of the steel plate. The end of the steel plate pushes the horizontal baffle 24 backward, causing the two drive belts 23 to rotate. The shearing length of the steel plate is measured by measuring the movement distance of the horizontal baffle 24, thereby improving the accuracy of steel plate shearing.

[0027] like Figures 1 to 7 As shown, this utility model discloses a steel coil shearing mechanism. During operation, the steel plate extracted from the coil is first laid flat on the front support plate 14. Multiple limiting wheels 16 roll and limit the left and right edges of the steel plate. The steel plate, after being rolled and limited by the limiting wheels 16, passes through the gap between the lower roller 4 and the upper roller 8 and is conveyed backward. During the conveying of the steel plate, bearings 3 and 7 allow the lower roller 4 and the upper roller 8 to rotate relative to the cutter shafts 2 and 6. Then, the end of the steel plate passes through the gap between the lower roller 4 and the upper roller 8 and is conveyed onto the rear support plate 20. The end of the steel plate abuts against the horizontal baffle 24. Two side baffles 25 limit the two side edges of the steel plate. The end of the steel plate pushes the horizontal baffle 24 backward, causing the two drive belts 23 to rotate. The horizontal baffle 24 is measured... The moving distance is used to measure the shearing length of the steel plate. Then, when the steel plate extends a certain length, the machine stops. The drive motor 12 drives the cutter shaft 2 to rotate through the transmission assembly 13. The cutter shaft 2 drives the gear 11 to rotate. The gear 11 meshes with the gear 10 to drive the cutter shaft 6 to rotate, so that the cutter shaft 2 and the cutter shaft 6 can rotate synchronously relative to each other. This allows the cutter shaft 2 to drive the lower cutter 5 and the cutter shaft 6 to drive the upper cutter 9 to rotate synchronously relative to each other. This makes the middle parts of the lower cutter 5 and the middle parts of the upper cutter 9 relatively close to each other and simultaneously shear the two sides of the steel plate, making the force on the two sides of the steel plate more balanced. Finally, while shearing the plate, the lower roller 4 and the upper roller 8 limit and clamp the steel plate on both sides of the lower cutter 5 and the upper cutter 9 to prevent the steel plate from shifting during shearing and improve the stability of shearing.

[0028] The main functions achieved by this utility model are:

[0029] 1. The steel plate is sheared on both sides simultaneously to make the force on both sides of the steel plate more balanced. At the same time as shearing, the lower roller 4 and the upper roller 8 limit and clamp the steel plate on both sides of the lower cutter 5 and the upper cutter 9 to prevent the steel plate from shifting during shearing and improve the stability of shearing.

[0030] 2. Limit the two sides and ends of the steel plate to improve the accuracy of shearing.

[0031] The shearing mechanism for steel coil shearing of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The frame 1, cutter shaft 1, bearing 1, lower roller 4, lower cutter 5, cutter shaft 2, bearing 2, upper roller 8, upper cutter 9, gear 1, gear 2, drive motor 12, transmission assembly 13, slide table 15, limit wheel 16, slide rail 17, double threaded screw 18, servo motor 19, drive wheel 1 21, drive wheel 2 22, and drive belt 23 of this utility model are commercially available.
