Description

Technical Field

[0001] This invention relates to the field of steel sheet shearing technology, and more specifically, to a high-precision adjustable steel sheet coil shearing device. Background Technology

[0002] Steel coils are coiled steel sheets rolled into a specific thickness and shape. They typically possess good formability and excellent mechanical properties, and are easy to process through shearing, bending, and welding. Due to the high strength and elasticity of steel sheets, they are widely used in various industrial fields.

[0003] Chinese patent application CN201821466938.2 discloses a device for shearing steel sheets, comprising a bearing blade structure, a main frame, and a motor. The bearing blade structure is located on one side of the main frame, and the motor is located below the main frame. The main frame includes a limiting rod, a limiter, a working plate, and support legs. The support legs are located at four right-angled ends of the working plate, forming a stool shape, with the other end of the support legs flush with the other side of the working plate. The limiting rod is parallel to the narrow edge of the working plate, and the upper surface of the limiting rod is engraved with centimeter graduations, with the 0-degree graduation flush with the outer surface of the bearing blade. Most of the components of this invention are recycled waste materials. The bearing blade is made from recycled scrap bearing steel, which has high hardness and can cut even harder steel sheets, while reducing costs.

[0004] Currently, some equipment uses a shearing blade fixedly installed above the steel sheet to cut it. To ensure cutting accuracy, the steel sheet feeding must be completely stopped during the cutting process. This intermittent operation method prevents the equipment from achieving continuous production and affects the cutting speed of the shearing blade on the steel sheet. When the length of the steel sheet to be cut is large, the tail of the equipment lacks a dynamic adjustment mechanism. During the cutting process, the steel sheet is prone to bending due to its own weight, causing the cutting position to deviate from the preset blade position, which affects the cutting accuracy of the shearing blade on the steel sheet. Moreover, after the traditional equipment completes the cutting, it often relies on manual unloading. Manual unloading is inefficient and affects the processing efficiency of the steel sheet. Summary of the Invention

[0012] Preferably, a lead screw is rotatably connected inside the fixed frame, the lead screw is threadedly connected to the movable block, a motor is fixedly mounted on one end surface of the fixed frame, the output end of the motor is fixedly connected to the lead screw, and a controller is fixedly mounted on the surface of one of the brackets, the controller is electrically connected to the motor through a wire, and the controller is electrically connected to the telescopic device through a wire.

[0013] Preferably, both scales have movable grooves on their surfaces, and a matching movable frame is slidably connected inside the movable groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) When this high-precision adjustable steel sheet coil shearing device is in use, the motor rotates and drives the lead screw to rotate. The moving block moves and drives the sliding plate to move. The sliding plate moves and drives the fixed column, carriage, and telescopic device to move. The telescopic device moves and drives the shearing device to move. At this time, the sliding plate and the shearing device move synchronously with the steel sheet body. During the synchronous movement, the telescopic device extends and drives the shearing device to move downward to shear the steel sheet body. Compared with the traditional intermittent shearing device, this shearing device realizes that the shearing device can cut the steel sheet body during the continuous conveying of the steel sheet body, which meets the requirements of continuous production and improves the cutting speed of the shearing device on the steel sheet body.

[0019] 2) When this high-precision adjustable steel sheet shearing device is in use, the sliding plate moves, carrying two trapezoidal blocks. The movement of the trapezoidal blocks causes the inclined plane to squeeze multiple rollers in sequence. After being squeezed, the rollers move upward, carrying the lifting frame upward. The movement of the lifting frame carries the rotating rods upward. When all the rollers have moved to the plane of the trapezoidal blocks, the multiple rotating rods are at the same horizontal plane. One end of the steel sheet body moves to the surface of the multiple rotating rods, and the multiple rotating rods support the steel sheet body. The shearer then cuts the steel sheet body, ensuring the flatness of the steel sheet body before shearing, preventing the shearer from shifting its position from the steel sheet body, ensuring the cutting accuracy of the shearer on the steel sheet body, and thus ensuring the cutting quality of the steel sheet body.

[0020] 3) When this high-precision adjustable steel sheet coil shearing device is in use, after shearing is completed, the telescopic device quickly resets the shear, the moving block resets the sliding plate and then the trapezoidal block. At this time, the moving block resets under the action of the first spring, causing the lifting frame to move downwards and the rotating rod to move downwards. After multiple lifting frames have reset, multiple rotating rods lower their heights in sequence to form a guide slope. At this time, the steel sheet body is fed along the formed guide slope under the action of gravity, which improves the processing efficiency of the steel sheet body.

[0021] 4) When using this high-precision adjustable steel sheet shearing device, the movable frame is manually adjusted to move inside the movable slot according to the length of the steel sheet to be cut. The movement of the movable frame moves the position sensor. When the position sensor reaches different positions on the scale, the steel sheet can be cut into different lengths.

[0022] 5) When this high-precision adjustable steel sheet shearing device is in use, when the slide plate and shearer move synchronously with the steel sheet body, the slide plate moves along with the moving plate, thereby conveying the end of the steel sheet body to the surface of the rotating rod. When the moving plate is squeezed by the limit rod, the moving plate moves toward the slide plate. At this time, the rotating wheel moves toward the slot. When the rotating wheel is squeezed by the chamfer, the rotating wheel moves downward, which in turn moves the lifting seat downward to squeeze the third spring. At this time, the moving plate is retracted into the slot, ensuring that the end of the steel sheet body is conveyed to the surface of the rotating rod, thereby ensuring the normal conveying of the steel sheet body during the shearing process.

[0037] Example 1: Please refer to Figure 1 - Figure 13A high-precision adjustable steel sheet coil shearing device includes a base 1 and corresponding brackets 2 fixedly mounted on its surface. Both brackets 2 have through-type grooves 3 on their surfaces. Matching sliders 4 are slidably connected inside the two grooves 3. A sliding plate 5 is fixedly mounted between the two sliders 4. A steel sheet body 7 is continuously conveyed on the surface of the sliding plate 5. A shearing device 6 for shearing the steel sheet body 7 is located above the sliding plate 5. The shearing device 6 is a conventional shearing blade. Trapezoidal blocks 8 are fixedly mounted on the outer surfaces of both sliders 4. A support frame 9 is fixedly mounted on one side of the base 1. Fixing plates 10 are correspondingly fixedly mounted on the inner sides of the support frame 9. Multiple slots 11 are formed on the inner walls of the two fixing plates 10. Multiple slots 11 have different lengths, which decrease sequentially towards the base 1. Multiple sets of lifting frames 12 are correspondingly arranged on the inner sides of the two fixed plates 10, with two lifting frames in each set. A roller 13 is rotatably connected to the bottom of any lifting frame 12. A rotating rod 14 is rotatably connected between each set of lifting frames 12. A matching moving block 15 is slidably connected inside any slot 11. The surface of the moving block 15 is fixedly connected to the surface of the lifting frame 12. The lifting frame 12 is slidably connected to the fixed plate 10 through the matching of the moving block 15 and the slot 11. A first spring 16 is elastically connected between the moving block 15 and the slot 11. The roller 13 contacts the surface of the trapezoidal block 8. When the steel sheet... When the cutting position of the body 7 is below the shearer 6, the motor 27 rotates, causing the lead screw 26 to rotate. The moving block 25 moves, causing the slide plate 5 to move. The movement of the slide plate 5 causes the fixed column 22, the carriage 19, and the telescopic device 20 to move. The movement of the telescopic device 20 causes the shearer 6 to move. At this time, the slide plate 5 and the shearer 6 move synchronously with the steel sheet body 7. During the synchronous movement, the telescopic device 20 extends, causing the shearer 6 to move downward to shear the steel sheet body 7. Compared with the traditional intermittent shearing device, this shearing device enables the shearer 6 to shear the steel sheet body 7 while the steel sheet body 7 is being continuously conveyed, meeting the requirements of continuous production and improving the cutting speed of the shearer 6 on the steel sheet body 7. The movement of the 5th movement carries the two trapezoidal blocks 8. The movement of the trapezoidal blocks 8 causes the ramp surface to press against the multiple rollers 13 in sequence. After being pressed, the rollers 13 move upward, carrying the lifting frame 12 upward. The movement of the lifting frame 12 carries the rotating rods 14 upward. When all the rollers 13 have moved to the plane of the trapezoidal blocks 8, the multiple rotating rods 14 are at the same horizontal plane. One end of the steel sheet body 7 moves to the surface of the multiple rotating rods 14, and the multiple rotating rods 14 support the steel sheet body 7. The shearer 6 then cuts the steel sheet body 7 to ensure the flatness of the steel sheet body 7 before cutting, prevent the shearer 6 from shifting its cutting position from the steel sheet body 7, ensure the cutting accuracy of the shearer 6 on the steel sheet body 7, and thus ensure the cutting quality of the steel sheet body 7.After shearing is completed, the telescopic device 20 quickly resets along with the shearer 6. The resetting motion of the movable block 25 causes the sliding plate 5 to reset, which in turn causes the trapezoidal block 8 to reset. At this time, the moving block 15 resets under the action of the first spring 16, causing the lifting frame 12 to move downwards, along with the rotating rod 14. After multiple lifting frames 12 have reset, multiple rotating rods 14 sequentially lower their height to form a guide ramp. At this time, the steel sheet body 7 is unloaded along the formed guide ramp under the action of gravity, improving the processing efficiency of the steel sheet body 7.

[0038] When the movable block 15 is in its initial state, the bottom surface of the movable block 15 is in contact with the inner bottom surface of the slot 11, one end of the first spring 16 is fixedly connected to the surface of the movable block 15, and the other end of the first spring 16 is fixedly connected to the inner wall of the slot 11. The first spring 16 is used for the movement reset of the movable block 15.

[0039] The trapezoidal block 8 includes a ramp surface and a plane. A guard plate 17 for limiting the roller 13 is fixedly installed along the ramp surface and plane of the trapezoidal block 8. The guard plate 17 is set to prevent the roller 13 from deviating when moving on the surface of the trapezoidal block 8. A mounting bracket 18 is fixedly installed on the inner side of each of the two brackets 2. The mounting bracket 18 is located above the slide groove 3. A slide 19 is slidably connected between the two mounting brackets 18. Multiple telescopic devices 20 are fixedly installed on the bottom surface of the slide 19. The telescopic ends of the multiple telescopic devices 20 are fixedly connected to the surface of the shearer 6. The telescopic device 20 is a conventional electrically controlled push rod in the prior art.

[0040] A protruding plate 21 is fixedly installed on the surface of the base 1. The height of the protruding plate 21 is the same as the height of the slide plate 5. The steel sheet body 7 is conveyed from the surface of the protruding plate 21 to the surface of the slide plate 5. A fixing column 22 is fixedly installed between the slide plate 5 and the slide frame 19. The protruding plate 21 is used to support the steel sheet body 7 in advance.

[0041] Both brackets 2 have rulers 23 fixedly installed on their inner sides. The rulers 23 are conventional rulers 23 in the prior art. The rulers 23 are located below the mounting bracket 18. A fixed bracket 24 is fixedly installed in the middle of the surface of the base 1. A matching movable block 25 is slidably connected inside the fixed bracket 24. The surface of the movable block 25 is fixedly connected to the bottom surface of the slide plate 5. In the initial state, the slider 4 is located inside the slide groove 3 near the protruding plate 21. The position of the shearer 6 corresponds to that of the slider 4. At this time, the shearer 6 and the slider 4 are at the zero mark of the ruler 23. According to the length of the steel sheet body 7 to be cut, the movable bracket 30 is manually adjusted to move inside the movable groove 29. The movement of the movable bracket 30 moves the position sensor 31. When the position sensor 31 moves to the same length as the steel sheet body 7 to be cut, the steel sheet body 7 can be cut into different lengths.

[0042] The fixed frame 24 is internally rotatably connected to a lead screw 26, which is threadedly connected to the movable block 25. A motor 27 is fixedly mounted on one end of the fixed frame 24. The motor 27 is a conventional forward and reverse motor in the prior art. The output end of the motor 27 is fixedly connected to the lead screw 26. A controller 28 is fixedly mounted on the surface of one of the brackets 2. The controller 28 is electrically connected to the motor 27 through wires and to the telescopic device 20 through wires. The controller 28 is a conventional programmable control device in the prior art. The position sensor 31 receives the signal and transmits the signal to the controller 28. The controller 28 receives and processes the signal and controls the rotation of the motor 27. The controller 28's control of the operation of the motor 27 and the telescopic device 20 is prior art and will not be described in detail here.

[0043] Both scales 23 have movable grooves 29 on their surfaces. A matching movable frame 30 is slidably connected inside the movable groove 29. A position sensor 31 is fixedly installed on the top of the movable frame 30. The position sensor 31 is electrically connected to the controller 28 via a wire. The position sensor 31 is a conventional position detector in the prior art.

[0044] A fixed seat 32 is fixedly installed between the corresponding surface of the base 1 and the inner wall of the two support frames 9. The surfaces of the two fixed seats 32 are provided with sliding grooves 33. A matching connecting block 34 is slidably connected inside the sliding groove 33. The top surface of the connecting block 34 is fixedly connected to the bottom surface of the trapezoidal block 8. The setting of the sliding groove 33 and the connecting block 34 ensures the stable movement of the trapezoidal block 8.

[0045] The usage steps of this invention are as follows: In the initial state, the slider 4 is positioned inside the slide groove 3 near the protruding plate 21, and the shearer 6 corresponds to the slider 4. At this time, the shearer 6 and slider 4 are at the zero mark on the scale 23. Based on the desired length of the steel sheet body 7 to be cut, the movable frame 30 is manually adjusted to move within the movable groove 29. The movement of the movable frame 30 moves the position sensor 31. When the position sensor 31 moves to the same length as the desired steel sheet body 7, the movement of the position sensor 31 stops. Then, the steel sheet body 7 is conveyed to the surface of the protruding plate 21 via the existing conveying equipment. As the steel sheet body 7 continues to be conveyed, the end of the steel sheet body 7 is conveyed to the surface of the sliding plate 5. When the end of the steel sheet body 7... When the signal is delivered to the position sensor 31, the position sensor 31 receives the signal and transmits it to the controller 28. The controller 28 receives and processes the signal, controlling the motor 27 to rotate. The motor 27 rotates forward, causing the lead screw 26 to rotate. At this time, the movable block 25 moves, causing the slide plate 5 to move. The movement of the slide plate 5 causes the fixed column 22, the slide frame 19, and the telescopic device 20 to move. The movement of the telescopic device 20 causes the shearer 6 to move. At this time, the slide plate 5 and the shearer 6 move synchronously with the steel sheet body 7. The movement of the slide plate 5 causes the two trapezoidal blocks 8 to move. The movement of the trapezoidal blocks 8 causes the ramp surface to press the multiple rollers 13 in sequence. After being pressed, the rollers 13 move upward, causing the lifting frame 12 to move upward. The movement of the lifting frame 12 causes the rotating rod 14 to move upward. At this time, the lifting frame 12 moves. The moving block 15 moves upward inside the slot 11, compressing the first spring 16. When all the rollers 13 move to the plane of the trapezoidal block 8, the multiple rotating rods 14 are on the same horizontal plane. As the slide plate 5 and the shearer 6 continue to move synchronously with the steel sheet body 7, one end of the steel sheet body 7 moves to the surface of the multiple rotating rods 14, and the multiple rotating rods 14 support the steel sheet body 7. Then, the controller 28 controls the multiple telescopic devices 20 to extend. The telescopic devices 20 extend and move the shearer 6 downward to shear the steel sheet body 7. After shearing, the telescopic devices 20 and the shearer 6 quickly reset. At this time, the motor 27 rotates in reverse, causing the lead screw 26 to rotate, so that the moving block 25 resets and the slide plate 5 resets. The reset movement of the slide plate 5 causes the telescopic devices to reset. The resetting motion of shear 6 and slide block 5 also causes trapezoidal block 8 to reset. At this time, moving block 15 resets under the action of the first spring 16, causing lifting frame 12 to move downwards, along with rotating rod 14. After multiple lifting frames 12 have reset, multiple rotating rods 14 decrease in height sequentially to form a guide ramp. At this time, steel sheet body 7 is fed down along the guide ramp under the action of gravity. In this scheme, when the cutting position of steel sheet body 7 is below shear 6, motor 27 rotates, causing lead screw 26 to rotate. Moving block 25 moves, causing slide block 5 to move. Slide block 5 moves, causing fixed column 22, slide 19 and telescopic device 20 to move. Telescopic device 20 moves, causing shear 6 to move. At this time, slide block 5 and shear 6 move synchronously with steel sheet body 7.During synchronous movement, the telescopic device 20 extends, carrying the shears 6 downward to shear the steel sheet body 7. Compared with the traditional intermittent shearing device, this shearing device enables the shears 6 to shear the steel sheet body 7 during continuous conveying, meeting the requirements of continuous production and improving the cutting speed of the shears 6 on the steel sheet body 7. The sliding plate 5 moves, carrying two trapezoidal blocks 8. The movement of the trapezoidal blocks 8 causes the ramp surface to squeeze multiple rollers 13 in sequence. After being squeezed, the rollers 13 move upward, carrying the lifting frame 12 upward. The movement of the lifting frame 12 carries the rotating rods 14 upward. When all the rollers 13 have moved to the plane of the trapezoidal blocks 8, the multiple rotating rods 14 are at the same horizontal plane. One end of the steel sheet body 7 moves to the surface of the multiple rotating rods 14, and multiple The rotating rod 14 supports the steel sheet body 7, and the shearer 6 then cuts the steel sheet body 7, ensuring the flatness of the steel sheet body 7 before cutting and preventing the shearer 6 from shifting its cutting position relative to the steel sheet body 7. This ensures the cutting accuracy of the shearer 6 on the steel sheet body 7, thereby guaranteeing the cutting quality of the steel sheet body 7. After cutting, the telescopic device 20 quickly resets the shearer 6, and the resetting motion of the movable block 25 causes the sliding plate 5 to reset, which in turn causes the trapezoidal block 8 to reset. At this time, the moving block 15 resets under the action of the first spring 16, causing the lifting frame 12 to move downwards, along with the rotating rod 14. After multiple lifting frames 12 have reset, multiple rotating rods 14 sequentially lower their height to form a guide ramp. At this time, the steel sheet body 7 is unloaded along the formed guide ramp under the action of gravity, improving the processing efficiency of the steel sheet body 7.

[0046] Example 2: Please refer to Figure 1 - Figure 13The difference from embodiment 1 is that a slot 35 is formed on one side surface of the slide plate 5, and a movable plate 36 is slidably connected inside the slot 35. A second spring 37 is elastically connected between the movable plate 36 and the slot 35. A plurality of lifting slots 38 are formed on the surface of the movable plate 36, and a matching lifting seat 39 is slidably connected inside any one of the lifting slots 38. A rotating rod 40 is rotatably connected inside the lifting seat 39, and a plurality of rotating wheels 41 are fixedly installed on the surface of the rotating rod 40. The rotating wheels 41 are rotatably connected to the lifting seat 39 through the rotating rod 40. Limiting rods 43 for limiting the movable plate 36 are fixedly installed on the inner sides of both support frames 9. By setting the movable plate 36 inside the slide plate 5, and the movable plate 36 being subjected to a second spring 37, the sliding plate 36 achieves its function. Spring 37 extends from slot 35, and moving plate 36 extends to support the end of steel sheet body 7. When slide plate 5 and shearer 6 move synchronously with steel sheet body 7, slide plate 5 moves and moves moving plate 36, thereby conveying the end of steel sheet body 7 to the surface of rotating rod 14. When moving plate 36 is squeezed by limit rod 43, moving plate 36 moves towards slide plate 5. At this time, rotating wheel 41 moves towards slot 35. When rotating wheel 41 is squeezed by chamfer 44, rotating wheel 41 moves downward and moves lifting seat 39 downward to squeeze third spring 42. At this time, moving plate 36 is stored inside slot 35 to ensure that the end of steel sheet body 7 is conveyed to the surface of rotating rod 14, thereby ensuring that steel sheet body 7 is conveyed normally during shearing.

[0047] A third spring 42 is elastically connected between the lifting groove 38 and the lifting seat 39. One end of the third spring 42 is fixedly connected to the inner bottom surface of the lifting groove 38, and the other end of the third spring 42 is fixedly connected to the bottom surface of the lifting seat 39. A chamfer 44 is provided on the inner top surface of the groove 35.

[0048] The invention's usage steps are as follows: When using this high-precision adjustable steel sheet coil shearing device, due to the distance difference between the sliding plate 5 and the rotating rod 14, to prevent the end of the steel sheet body 7 from bending downwards under gravity during transport and to ensure that the end of the steel sheet body 7 is transported to the surface of the rotating rod 14, a movable plate 36 is installed inside the sliding plate 5. This movable plate 36 extends from the slot 35 under the influence of a second spring 37. After extending, the movable plate 36 supports the end of the steel sheet body 7. When the sliding plate 5 and the shearer 6 move synchronously with the steel sheet body 7, the sliding plate... The movement of the moving plate 36, along with the movement of the moving plate 5, transports the end of the steel sheet body 7 to the surface of the rotating rod 14. When the moving plate 36 is pressed by the limiting rod 43, it moves towards the sliding plate 5. At this time, the rotating wheel 41 moves towards the slot 35. When the rotating wheel 41 is pressed by the chamfer 44, it moves downward, causing the lifting seat 39 to move downward and press the third spring 42. At this time, the moving plate 36 is stored inside the slot 35, ensuring that the end of the steel sheet body 7 is transported to the surface of the rotating rod 14, thus ensuring that the steel sheet body 7 is transported normally during the shearing process.
