Description

Technical Field

[0001] The present invention relates to the technical field of steel sheet shearing, and more particularly to a high-precision adjustable steel sheet coil shearing device. Background Art

[0002] Steel coils are made of steel sheets rolled into a specific thickness and shape. They usually have good formability and excellent mechanical properties, and are easy to process such as shearing, bending and welding. Due to their high strength and elasticity, steel sheets are widely used in various industrial fields. Chinese patent application number CN201821466938.2 discloses a device for shearing steel sheets, which includes a bearing knife structure, a main frame, and a motor. The bearing knife structure is arranged on one side of the main frame, and the motor is arranged below the main frame. The main frame includes a limit rod, a limiter, a work plate, and support legs. The support legs are arranged at four right angles to the lower surface of the work plate, forming a stool shape, and the side surface of the other end is flush with the other side surface of the work plate. The limit rod is parallel to the narrow side of the work plate. The upper surface of the limit rod is engraved with a centimeter scale, and the 0 scale is flush with the outer side surface of the bearing knife. Most of the components of this utility model are recycled waste. The bearing knife is made by processing and recycling waste bearing steel. The bearing knife has high hardness and can cut harder steel sheets, while reducing costs.

[0003] At present, some equipment uses a shear knife fixedly installed above the steel sheet to shear the steel sheet. In order to ensure cutting accuracy, the steel sheet conveying needs to be completely stopped during the shearing process. This intermittent operation mode makes it impossible for the equipment to achieve continuous production, affecting the shearing speed of the steel sheet by the shear knife. When the length of the steel sheet to be sheared is large, the tail of the equipment lacks a dynamic adjustment mechanism. During the shearing process, the steel sheet is easily bent due to its own weight, causing the shearing position to deviate from the preset knife position, affecting the shearing accuracy of the steel sheet by the shear knife. Moreover, some traditional equipment often relies on manual unloading operations after shearing. The efficiency of manual intervention in unloading is low, which affects the processing efficiency of the steel sheet. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) When the present high-precision adjustable steel sheet coil shearing device is in use, when the cutting position of the steel sheet body is below the shearing device, at this time, the motor is rotating forward to drive the lead screw to rotate. The movable block moves to drive the sliding plate to move. The sliding plate moves to drive the fixed column, the sliding frame and the telescopic device to move. The telescopic device moves to drive 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 to drive the shearing device to move downward to shear the steel sheet body. Compared with the traditional intermittent shearing device, this shearing device realizes that during the continuous conveying process of the steel sheet body, the shearing device can shear the steel sheet body, meeting the requirements of continuous production and improving the cutting speed of the shearing device for the steel sheet body.

[0015] 2) When this high-precision adjustable steel sheet coil shearing device is in use, the sliding plate moves, driving two trapezoidal blocks to move. The movement of the trapezoidal blocks causes the inclined planes to sequentially squeeze multiple rollers. After being squeezed, the rollers move upward, driving the lifting frame upward. The movement of the lifting frame drives the rotating rod upward. When multiple rollers all move onto the flat surface of the trapezoidal block, at this time, multiple rotating rods are on the same horizontal plane. One end of the steel sheet body moves onto the surfaces of multiple rotating rods, and multiple rotating rods support the steel sheet body. Then the shearer shears the steel sheet body, ensuring the flatness of the steel sheet body before shearing, preventing the deviation of the shearing position of the shearer from the steel sheet body, guaranteeing the cutting accuracy of the shearer for the steel sheet body, and thus ensuring the cutting quality of the steel sheet body.

[0016] 3) When this high-precision adjustable steel sheet coil shearing device is in use, after shearing is completed, the telescopic device drives the shearer to quickly reset. The reset movement of the movable block drives the sliding plate to reset, and then drives the trapezoidal block to reset. At this time, the moving block resets under the action of the first spring, causing the lifting frame to move downward and drive the rotating rod to move downward. When multiple lifting frames are reset, multiple rotating rods sequentially lower their heights to form a guiding slope. At this time, the steel sheet body moves downward along the formed guiding slope under the action of gravity, improving the processing efficiency of the steel sheet body.

[0017] 4) When this high-precision adjustable steel sheet coil shearing device is in use, according to the length of the steel sheet body to be cut, manually adjust the movement of the movable frame inside the movable slot. The movement of the movable frame drives the position sensor to move. When the position sensor reaches different positions on the scale, the steel sheet body can be cut into different lengths.

[0018] 5) When this high-precision adjustable steel sheet coil shearing device is in use, when the sliding plate and the shearer move synchronously with the steel sheet body, the sliding plate moves and drives the moving plate to move, and then conveys the end of the steel sheet body to the surface of the rotating rod. When the moving plate is squeezed by the limiting rod, the moving plate moves towards the sliding plate. At this time, the rotating wheel moves towards the notch direction. When the movement of the rotating wheel is squeezed by the chamfer, at this time, the rotating wheel moves downward, driving the lifting seat to move downward and squeeze the third spring. At this time, the moving plate is received into the notch, ensuring that the end of the steel sheet body is conveyed to the surface of the rotating rod, and thus ensuring the normal conveyance of the steel sheet body during the shearing process.

Detailed implementation manners

[0021] Embodiment 1: Please refer to Figure 1 - Figure 13A high-precision adjustable steel sheet coil shearing device includes a base 1 and a bracket 2 fixedly mounted on its surface. The surfaces of the two brackets 2 are both provided with a through-type slide groove 3. The two slide grooves 3 are internally slidably connected with a slider 4 matching them. A slide plate 5 is fixedly mounted between the two sliders 4. The surface of the slide plate 5 is provided with a steel sheet body 7 for continuous transmission. A shear 6 for shearing the steel sheet body 7 is provided above the slide plate 5. The shear 6 is a conventional shearing knife in the prior art. A trapezoidal block 8 is fixedly mounted on the outer surfaces of the two sliders 4. A support frame 9 is fixedly mounted on one side of the base 1. A fixed plate 10 is fixedly mounted on the inner side of the support frame 9. The inner walls of the two fixed plates 10 are provided with a plurality of slots 11. The lengths of the multiple slots 11 are different, and the lengths of the multiple slots 11 gradually decrease toward the base 1. Multiple groups of lifting frames 12 are correspondingly provided on the inner sides of the two fixed plates 10. The number of each group of lifting frames 12 is two. The bottom of any lifting frame 12 is rotatably connected to a roller 13. A rotating rod 14 is rotatably connected between each group of lifting frames 12. The interior of any slot 11 is slidably connected to a matching moving block 15. 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 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 main body 7 is located below the shear 6, the motor 27 is rotating and driving the screw 26 to rotate. The movable block 25 moves and drives the slide plate 5 to move. The slide plate 5 moves and drives the fixed column 22, the slide 19 and the telescopic device 20 to move. The telescopic device 20 moves and drives the shear 6 to move. At this time, the slide plate 5 and the shear 6 move synchronously with the steel sheet main body 7. During the synchronous movement, the telescopic device 20 extends and drives the shear 6 to move downward to shear the steel sheet main body 7. Compared with the traditional intermittent shearing device, the shearing device realizes that the shear 6 can shear the steel sheet main body 7 during the continuous conveying process of the steel sheet main body 7, thereby meeting the requirements of continuous production and improving the cutting speed of the shear 6 on the steel sheet main body 7; 5 moves with the two trapezoidal blocks 8, and the movement of the trapezoidal blocks 8 causes the slope to face the multiple rollers 13 and squeeze them in sequence. After being squeezed, the rollers 13 move upward and bring the lifting frame 12 upward. The lifting frame 12 moves and brings the rotating rods 14 upward. When the multiple rollers 13 all move to the plane of the trapezoidal block 8, the multiple rotating rods 14 are on 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 shears 6 then shears the steel sheet body 7, ensuring that the steel sheet body 7 is flat before shearing, preventing the shears 6 and the steel sheet body 7 from offsetting the shearing position, ensuring the cutting accuracy of the steel sheet body 7 by the shears 6, and thus ensuring the cutting quality of the steel sheet body 7.After the shearing is completed, the expander 20 drives the shearer 6 to quickly reset. The reset movement of the movable block 25 drives the skateboard 5 to reset, and then drives the trapezoidal block 8 to reset. At this time, the moving block 15 resets under the action of the first spring 16, so that the lifting frame 12 moves downward and drives the rotating rod 14 to move downward. When multiple lifting frames 12 are reset, multiple rotating rods 14 are successively lowered to form a guiding slope. At this time, the steel sheet body 7 is fed along the formed guiding slope under the action of gravity, improving the processing efficiency of the steel sheet body 7.;

[0022] When the moving block 15 is in the initial state, the bottom surface of the moving block 15 contacts the inner bottom surface of the slot 11. One end of the first spring 16 is fixedly connected to the surface of the moving 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 moving block 15.

[0023] The trapezoidal block 8 includes a slope surface and a flat surface. Guard plates 17 for limiting the rollers 13 are fixedly installed along the slope surface and the flat surface of the trapezoidal block 8. The arrangement of the guard plates 17 prevents the rollers 13 from shifting when moving on the surface of the trapezoidal block 8. Mounting frames 18 are fixedly installed on the inner sides of the two brackets 2. The mounting frames 18 are located above the sliding grooves 3. A sliding frame 19 is slidably connected between the two mounting frames 18. A plurality of expanders 20 are fixedly installed on the bottom surface of the sliding frame 19.

A fixing column 22 is fixedly installed between the skateboard 5 and the sliding frame 19. The protruding plate 21 is used for the preliminary support of the steel sheet body 7.

[0025] Scale bars 23 are fixedly installed on the inner sides of the two brackets 2. The scale bars 23 are conventional scale bars 23 in the prior art. The scale bars 23 are located below the mounting frames 18. A fixing frame 24 is fixedly installed in the middle of the surface of the base 1. An activity block 25 that matches it is slidably connected inside the fixing frame 24. The surface of the activity block 25 is fixedly connected to the bottom surface of the skateboard 5. In the initial state, the slider 4 is inside the sliding groove 3 near the protruding plate 21, and the shearer 6 corresponds to the position of the slider 4. At this time, the shearer 6 and the slider 4 are at the zero scale position of the scale bar 23. According to the length of the steel sheet body 7 to be cut, manually adjust the movement of the movable frame 30 inside the movable groove 29. The movement of the movable frame 30 drives the position sensor 31 to move. 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.

[0026] A lead screw 26 is rotatably connected inside the fixing frame 24. The lead screw 26 is threadedly connected to the movable block 25. A motor 27 is fixedly installed on the surface of one end of the fixing 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 installed on the surface of one of the brackets 2. The controller 28 is electrically connected to the motor 27 through a wire, and the controller 28 is electrically connected to the telescopic device 20 through a wire. The controller 28 is a conventional programmable control device in the prior art. The position sensor 31 receives a signal and transmits the signal to the controller 28. The controller 28 receives the signal and processes it to control the rotation of the motor 27. The controller 28 controls the operation of the motor 27 and the operation of the telescopic device 20, which is the prior art and will not be elaborated here too much.

[0027] Activity grooves 29 are formed on the surfaces of both of the two scales 23. An activity frame 30 that matches the activity groove 29 is slidably connected inside the activity groove 29. A position sensor 31 is fixedly installed on the top of the activity frame 30. The position sensor 31 is electrically connected to the controller 28 through a wire. The position sensor 31 is a conventional position detector in the prior art.

[0028] A fixed seat 32 is fixedly installed between the corresponding surface of the base 1 and the inner walls of the two support frames 9. Sliding grooves 33 are formed on the surfaces of both of the two fixed seats 32. A connecting block 34 that matches the sliding groove 33 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 arrangement of the sliding groove 33 and the connecting block 34 ensures the stable movement of the trapezoidal block 8.

[0029] Steps of using the present invention: When the high-precision adjustable steel sheet coil shearing device is in use, in the initial state, the slider 4 is inside the chute 3 near the protruding plate 21, and the shearing cutter 6 corresponds to the position of the slider 4. At this time, the shearing cutter 6 and the slider 4 are at the zero scale position of the scale 23. According to the length of the steel sheet body 7 to be cut, manually adjust the movable frame 30 to move inside the movable slot 29. The movement of the movable frame 30 drives the position sensor 31 to move. When the position sensor 31 moves to the same length as the steel sheet body 7 to be cut, stop the movement of the position sensor 31. Then, the steel sheet body 7 is sent to the surface of the protruding plate 21 through an existing conveying device. 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 slide plate 5. When the end of the steel sheet body 7 is conveyed to the position of the position sensor 31, at this time, the position sensor 31 receives the signal and transmits the signal to the controller 28. The controller 28 receives the signal and processes it, controlling the motor 27 to rotate. The positive rotation of the motor 27 drives the lead screw 26 to rotate. At this time, the movable block 25 moves to drive the slide plate 5 to move. The movement of the slide plate 5 drives the fixed column 22, the carriage 19, and the telescopic device 20 to move. The movement of the telescopic device 20 drives the shearing cutter 6 to move. At this time, the slide plate 5 and the shearing cutter 6 move synchronously with the steel sheet body 7. The movement of the slide plate 5 drives the two trapezoidal blocks 8 to move. The movement of the trapezoidal blocks 8 causes the inclined planes to sequentially press on the multiple rollers 13. After being pressed, the rollers 13 move upward to drive the lifting frame 12 to move upward. The movement of the lifting frame 12 drives the rotating rod 14 to move upward. At this time, the movement of the lifting frame 12 also drives the moving block 15 to move upward inside the slot 11 to press the first spring 16. When all the multiple rollers 13 move to the plane of the trapezoidal blocks 8, at this time, the multiple rotating rods 14 are on the same horizontal plane. As the slide plate 5 and the shearing cutter 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 work and extend. The extension of the telescopic devices 20 drives the shearing cutter 6 to move downward to cut the steel sheet body 7. After cutting, the telescopic device 20 drives the shearing cutter 6 to quickly reset. At this time, the reverse rotation of the motor 27 drives the lead screw 26 to rotate, causing the movable block 25 to move in the reverse direction to drive the slide plate 5 to move in the reverse direction. The reverse movement of the slide plate 5 drives the telescopic device 20 and the shearing cutter 6 to move in the reverse direction. The reverse movement of the slide plate 5 also drives 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 downward to drive the rotating rod 14 to move downward. When all the multiple lifting frames 12 are reset, the multiple rotating rods 14 sequentially decrease in height to form a guiding slope. At this time, the steel sheet body 7 falls along the formed guiding slope under the action of gravity. In this solution, when the cutting position of the steel sheet body 7 is below the shearing cutter 6, at this time, the positive rotation of the motor 27 drives the lead screw 26 to rotate. The movement of the movable block 25 drives the slide plate 5 to move. The movement of the slide plate 5 drives the fixed column 22, the carriage 19, and the telescopic device 20 to move. The movement of the telescopic device 20 drives the shearing cutter 6 to move. At this time, the slide plate 5 and the shearing cutter 6 move synchronously with the steel sheet body 7.During the synchronous movement, the expander 20 extends and drives 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 during the continuous conveyance of the steel sheet body 7, meeting the requirements of continuous production and increasing the cutting speed of the shearer 6 for the steel sheet body 7. The slide plate 5 moves and drives the two trapezoidal blocks 8 to move. The movement of the trapezoidal blocks 8 causes the inclined planes to sequentially press against multiple rollers 13. After being pressed, the rollers 13 move upward and drive the lifting frame 12 to move upward. The movement of the lifting frame 12 drives the rotating rod 14 to move upward. When multiple rollers 13 all move onto the plane of the trapezoidal block 8, multiple rotating rods 14 are at the same horizontal plane at this time. One end of the steel sheet body 7 moves onto the surfaces of multiple rotating rods 14, and multiple rotating rods 14 support the steel sheet body 7. Then the shearer 6 shears the steel sheet body 7, ensuring the flatness of the steel sheet body 7 before shearing, preventing the deviation of the shearing position between the shearer 6 and the steel sheet body 7, guaranteeing the cutting accuracy of the shearer 6 for the steel sheet body 7, and thus ensuring the cutting quality of the steel sheet body 7. After shearing, the expander 20 drives the shearer 6 to quickly reset. The reset movement of the movable block 25 drives the slide plate 5 to reset and further drives 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 downward and drive the rotating rod 14 to move downward. When multiple lifting frames 12 complete the reset, multiple rotating rods 14 sequentially decrease in height to form a guiding slope. At this time, the steel sheet body 7 falls along the formed guiding slope under the action of gravity, improving the processing efficiency of the steel sheet body 7.,

[0030] Embodiment 2: Please refer to Figure 1 - Figure 13, the difference from the basis of Embodiment 1 is that a notch 35 is formed on one side surface of the skateboard 5, a moving plate 36 is slidably connected inside the notch 35, a second spring 37 is elastically connected between the moving plate 36 and the notch 35, a plurality of lifting grooves 38 are formed on the surface of the moving plate 36, and a lifting seat 39 matching therewith is slidably connected inside any one of the lifting grooves 38. A rotating rod 40 is rotatably connected inside the lifting seat 39, a plurality of rotating wheels 41 are fixedly installed on the surface of the rotating rod 40, the rotating wheels 41 are rotatably connected with the lifting seat 39 through the rotating rod 40, and limiting rods 43 for limiting the moving plate 36 are fixedly installed on the inner side surfaces of the two support frames 9. By arranging the moving plate 36 inside the skateboard 5, and the moving plate 36 extends out of the notch 35 under the action of the second spring 37. After the moving plate 36 extends out, it supports the end of the steel sheet body 7. When the skateboard 5 and the shearing device 6 move synchronously with the steel sheet body 7, the movement of the skateboard 5 drives the movement of the moving plate 36, and then conveys the end of the steel sheet body 7 to the surface of the rotating rod 14. When the moving plate 36 is extruded by the limiting rod 43, the moving plate 36 moves towards the skateboard 5. At this time, the rotating wheel 41 moves towards the notch 35. When the rotating wheel 41 is extruded by the chamfer 44 during movement, at this time, the rotating wheel 41 moves downward, driving the lifting seat 39 to move downward and extruding the third spring 42. At this time, the moving plate 36 is received inside the notch 35, ensuring that the end of the steel sheet body 7 is conveyed to the surface of the rotating rod 14, and thus ensuring the normal conveyance of the steel sheet body 7 during the shearing process.

[0031] 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 arranged on the inner top surface of the notch 35.

[0032] Steps of using the present invention: When the high-precision adjustable steel sheet coil shearing device is in use, due to the distance difference between the sliding plate 5 and the rotating rod 14, during the conveying process of the steel sheet body 7, in order to prevent the end of the steel sheet body 7 from bending downward due to gravity and ensure that the end of the steel sheet body 7 is conveyed to the surface of the rotating rod 14, a moving plate 36 is arranged inside the sliding plate 5, and the moving plate 36 extends out of the notch 35 under the action of the second spring 37. After the moving plate 36 extends out, it supports the end of the steel sheet body 7. When the sliding plate 5 and the shearing device 6 move synchronously with the steel sheet body 7, the movement of the sliding plate 5 drives the movement of the moving plate 36, thereby conveying the end of the steel sheet body 7 to the surface of the rotating rod 14. When the moving plate 36 is squeezed by the limiting rod 43, the moving plate 36 moves towards the sliding plate 5. At this time, the rotating wheel 41 moves towards the notch 35. When the movement of the rotating wheel 41 is squeezed by the chamfer 44, at this time, the rotating wheel downward movement drives the lifting seat 39 to move downward and squeeze the third spring 42. At this time, the moving plate 36 is received inside the notch 35, ensuring that the end of the steel sheet body 7 is conveyed to the surface of the rotating rod 14, and thus ensuring the normal conveyance of the steel sheet body 7 during the shearing process.
