Abstract
Description
Technical Field
[0001] This application relates to the field of metal processing technology, and in particular to a positioning and cutting device for thin metal sheets. Background Technology
[0002] Metal sheets can be processed into products with specific functions through cold working processes such as shearing, punching / cutting / combined cutting, folding, riveting, splicing, and forming to meet the needs of users. When cutting metal sheets, they need to be cut to the required dimensions.
[0003] When using existing cutting equipment, if the positioning pressure on the metal sheet is too low, the metal sheet is prone to vibration or movement when subjected to cutting force, resulting in large errors. If the positioning pressure on the metal sheet is too high, it may cause the metal sheet to deform under pressure.
[0004] Therefore, this application provides a metal sheet positioning and cutting device. Utility Model Content
[0005] In view of the shortcomings of the prior art, this application provides a metal sheet positioning and cutting device, which overcomes the shortcomings of the prior art and aims to solve the problem that if the positioning pressure on the metal sheet is too small when the existing cutting device is used, the metal sheet will easily vibrate or move when subjected to cutting force, resulting in large errors. If the positioning pressure on the metal sheet is too large, it may cause the metal sheet to deform under pressure.
[0006] To achieve the above objectives, this application provides the following technical solution: a metal sheet positioning and cutting device, comprising a cutting table, four sets of uprights fixedly connected to the top of the cutting table, a top plate fixedly connected to the top of the four sets of uprights, two sets of three-dimensional adjustment mechanisms symmetrically arranged at the top of the cutting table, two sets of positioning plates movably connected to the three-dimensional adjustment mechanisms, two sets of hydraulic cylinders fixedly installed at the bottom of the top plate, a ring frame installed at the output end of the two sets of hydraulic cylinders, a screw rod rotatably connected inside the ring frame, a reciprocating motor fixedly installed inside the ring frame, the output end of the reciprocating motor fixedly installed to one end of the screw rod, a movable sleeve threadedly connected to the outer surface of the screw rod, a protective box installed at the bottom of the movable sleeve, an electric cutter installed at the bottom of the protective box, connecting plates fixedly installed on both sides of the movable sleeve, two sets of springs installed at the bottom of the connecting plates, an inverted C-shaped seat installed at the bottom of the two sets of springs, and a pressure roller installed at the bottom of the inverted C-shaped seat.
[0007] By adopting the above technical solution, the thin metal sheet is placed at the top of the cutting table. Two sets of hydraulic rods retract to drive the three-dimensional adjustment mechanism and positioning plate to move downwards. Four sets of positioning plates fix the four corners of the thin metal sheet. Two sets of hydraulic cylinders extend to push the ring frame downwards. Then, the electric cutter is started to cut the thin metal sheet. At this time, the pressure roller strengthens the fixing of the cutting area of the thin metal sheet, and two sets of springs effectively absorb vibration, improving the cutting accuracy of the thin metal sheet. At the same time, the reciprocating motor is started to drive the screw to rotate, so that the moving sleeve drives the electric cutter to move and cut the thin metal sheet. When the moving sleeve moves, it drives the connecting plate to move in conjunction, so that the pressure roller moves synchronously with the electric cutter, effectively absorbing vibration in the cutting area of the thin metal sheet and reducing the error of the thin metal sheet during cutting.
[0008] As a preferred technical solution of this application, the three-dimensional adjustment mechanism includes a rectangular plate, a hydraulic rod installed between the rectangular plate and the cutting table, a screw rod connected internally to the rectangular plate, a movable box rotatably connected to one end of the screw rod, two sets of telescopic rods installed between the rectangular plate and the movable box, a double-headed motor fixedly installed inside the movable box, a screw rod installed at each of the two output ends of the double-headed motor, a movable block threadedly connected to the outer surface of the screw rod, a connecting rod fixedly installed at the bottom end of the movable block, the connecting rod slidably connected to the movable box, and the bottom end of the connecting rod fixedly installed to the corresponding positioning plate.
[0009] By adopting the above technical solution, after the metal sheet is placed at the top of the cutting table, the screw is rotated to move the box and positioning plate according to the length of the metal sheet. Then, according to the width of the metal sheet, the double-headed motor is started to drive the screw to rotate, so that the two sets of moving blocks move under the action of the screw. The two sets of positioning plates are adjusted to move closer or further apart. Finally, according to the thickness of the metal sheet, the hydraulic rod is contracted until the positioning plate touches the top surface of the metal sheet, thereby improving the applicability of metal sheets of different sizes.
[0010] As a preferred technical solution of this application, a second spring is installed at the top of the connecting plate, a slider is installed at the top of the second spring, and two sets of sliding grooves are opened at the bottom of the top plate, with the two sets of second springs slidably connected to the sliding ends of the two sets of sliding grooves respectively.
[0011] By adopting the above technical solution, the pressure adaptive adjustment capability of the pressure roller is further improved by the second spring, and when the pressure roller is displaced, the slider slides along the groove, which improves the guidance of the pressure roller when it moves.
[0012] As a preferred technical solution of this application, the pressure roller is rotatably connected to the inside of the inverted C-shaped seat.
[0013] By adopting the above technical solution, the pressure roller rotates within the inverted C-shaped seat during displacement and rolls into contact with the top surface of the metal sheet, thereby improving the smoothness of the pressure roller's movement along the metal sheet.
[0014] As a preferred technical solution of this application, a rubber layer is fixedly installed on the outer surface of the pressure roller and the bottom end of the positioning plate.
[0015] By adopting the above technical solution, the shock absorption effect of the pressure roller is further improved through the rubber layer, which further reduces the risk of thin plate deformation. At the same time, the rubber layer reduces the friction between the positioning plate and the pressure roller on the surface of the thin metal plate, thereby improving the protection effect of the thin metal plate.
[0016] As a preferred technical solution of this application, the spring 2 is provided with a telescopic guide rod inside, and the telescopic guide rod is installed between the connecting plate and the slider.
[0017] By adopting the above technical solution, the spring 2 is guided by the telescopic guide rod, which helps to extend the service life of the spring 2.
[0018] As a preferred technical solution of this application, a controller is fixedly installed on the front surface of the cutting table, and the controller is electrically connected to the control ends of the reciprocating motor, the double-headed motor and the hydraulic rod.
[0019] By adopting the above technical solution and setting the parameters of the reciprocating motor, the double-headed motor, and the hydraulic rod through the controller, the degree of automation in controlling the positioning pressure of the thin metal sheet is improved.
[0020] The beneficial effects of this application are:
[0021] 1. Place the thin metal sheet at the top of the cutting table. Two sets of hydraulic rods retract, driving the three-dimensional adjustment mechanism and positioning plates to move downwards. Four sets of positioning plates fix the four corners of the thin metal sheet. Two sets of hydraulic cylinders extend, pushing the ring frame downwards. Then, the electric cutter is started to cut the thin metal sheet. At this time, the pressure roller reinforces the cutting area of the thin metal sheet, and two sets of springs effectively absorb vibration, improving the cutting accuracy of the thin metal sheet. Simultaneously, the reciprocating motor is started, driving the screw to rotate, causing the moving sleeve to move the electric cutter to cut the thin metal sheet. When the moving sleeve moves, it drives the connecting plate to move, so that the pressure roller moves synchronously with the electric cutter, effectively absorbing vibration in the cutting area of the thin metal sheet and reducing the error during cutting.
[0022] 2. After placing the metal sheet at the top of the cutting table, adjust the moving box and positioning plate by rotating screw one according to the length of the metal sheet. Then, according to the width of the metal sheet, start the double-headed motor to drive screw two to rotate, so that the two sets of moving blocks move under the action of the screw two thread. Adjust the two sets of positioning plates to move closer or further apart. Finally, according to the thickness of the metal sheet, retract the hydraulic rod until the positioning plate abuts against the top surface of the metal sheet, thereby improving the applicability of metal sheets of different sizes.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] Reference Figure 1-4A metal sheet positioning and cutting device includes a cutting table 1, four sets of uprights 2 fixedly connected to the top of the cutting table 1, a top plate 3 fixedly connected to the top of the four sets of uprights 2, two sets of three-dimensional adjustment mechanisms 4 symmetrically arranged at the top of the cutting table 1, two sets of positioning plates 5 movably connected to the three-dimensional adjustment mechanisms 4, two sets of hydraulic cylinders 6 fixedly installed at the bottom of the top plate 3, a ring frame 7 installed at the output end of the two sets of hydraulic cylinders 6, a screw 9 rotatably connected inside the ring frame 7, a reciprocating motor 8 fixedly installed inside the ring frame 7, and the output end of the reciprocating motor 8 fixedly installed at one end of the screw 9. The outer surface is threaded with a movable sleeve 10. A protective box 11 is installed at the bottom of the movable sleeve 10. An electric cutter 12 is installed at the bottom of the protective box 11. Connecting plates 13 are fixedly installed on both sides of the movable sleeve 10. Two sets of springs 14 are installed at the bottom of the connecting plates 13. An inverted C-shaped seat 15 is installed at the bottom of the two sets of springs 14. A pressure roller 16 is installed at the bottom of the inverted C-shaped seat 15. A second spring 17 is installed at the top of the connecting plates 13. A slider 18 is installed at the top of the second spring 17. Two sets of sliding grooves 19 are opened at the bottom of the top plate 3. The two sets of springs 17 are slidably connected to the sliding ends of the two sets of sliding grooves 19 respectively.
[0030] The thin metal sheet is placed at the top of the cutting table 1. Two sets of hydraulic rods 409 retract, driving the three-dimensional adjustment mechanism 4 and positioning plate 5 to move downwards. The four sets of positioning plates 5 fix the four corners of the thin metal sheet. Two sets of hydraulic cylinders 6 extend, pushing the ring frame 7 downwards. Then, the electric cutter 12 is started to cut the thin metal sheet. At this time, the pressure roller 16 reinforces and fixes the cutting area of the thin metal sheet, and the two sets of springs 14 effectively absorb vibration, improving the cutting accuracy of the thin metal sheet. At the same time, the reciprocating motor 8 is started, driving the screw 9 to rotate, causing the moving sleeve 10 to move the electric cutter 12 to cut the thin metal sheet. When the moving sleeve 10 moves, it drives the connecting plate 13 to move, so that the pressure roller 16 moves synchronously with the electric cutter 12, effectively absorbing vibration in the cutting area of the thin metal sheet and reducing the error of the thin metal sheet during cutting. The pressure roller 16's pressure self-adjustment capability is further improved by the spring 17, and when the pressure roller 16 moves, the slider 18 slides along the groove 19, improving the guidance of the pressure roller 16 during movement.
[0031] Reference Figure 2-4The three-dimensional adjustment mechanism 4 includes a rectangular plate 401. A hydraulic rod 409 is installed between the rectangular plate 401 and the cutting table 1. A screw 402 is threadedly connected inside the rectangular plate 401. One end of the screw 402 is rotatably connected to a movable box 403. Two sets of telescopic rods 404 are installed between the rectangular plate 401 and the movable box 403. A dual-head motor 405 is fixedly installed inside the movable box 403. Screws 406 are installed at both output ends of the dual-head motor 405. A movable block 407 is threadedly connected to the outer surface of the screw 406. A connecting rod 408 is fixedly installed at the bottom end of the movable block 407. The connecting rod 408 is slidably connected to the movable box 403. The bottom end of the connecting rod 408 is fixedly installed with the corresponding positioning plate 5. The pressure roller 16 is rotatably connected to the inside of the inverted C-shaped seat 15.
[0032] After placing the metal sheet at the top of the cutting table 1, adjust the screw 402 according to the length of the metal sheet by rotating the moving box 403 and the positioning plate 5. Then, according to the width of the metal sheet, start the double-head motor 405 to drive the screw 406 to rotate, so that the two sets of moving blocks 407 move under the action of the screw 406. Adjust the two sets of positioning plates 5 to move closer or further apart. Finally, according to the thickness of the metal sheet, retract the hydraulic rod 409 until the positioning plate 5 touches the top surface of the metal sheet, thereby improving the applicability of metal sheets of different sizes. When the pressure roller 16 is displaced, it rotates in the inverted C-shaped seat 15 and rolls in contact with the top surface of the metal sheet, which improves the smoothness of the pressure roller 16 when moving along the metal sheet.
[0033] Reference Figure 1-4 Rubber layers 20 are fixedly installed on the outer surface of the pressure roller 16 and the bottom end of the positioning plate 5. A controller 22 is fixedly installed on the front surface of the cutting table 1. The controller 22 is electrically connected to the control ends of the reciprocating motor 8, the double-head motor 405, and the hydraulic rod 409. The rubber layer 20 further improves the shock absorption effect of the pressure roller 16 and further reduces the risk of thin plate deformation. At the same time, the rubber layer 20 reduces the friction between the positioning plate 5 and the pressure roller 16 on the surface of the metal sheet, thus improving the protection effect of the metal sheet. The controller 22 improves the automation level of the positioning pressure control of the metal sheet by setting the parameters of the reciprocating motor 8, the double-head motor 405, and the hydraulic rod 409.
[0034] Reference Figure 2 The second spring 17 has a telescopic guide rod 21 installed inside, which is installed between the connecting plate 13 and the slider 18. The telescopic guide rod 21 guides the second spring 17, which helps to extend the service life of the second spring 17.
[0035] Working principle: The thin metal sheet is placed on top of the cutting table 1. Based on the length of the sheet, the screw 402 is rotated to move the moving box 403 and positioning plate 5 for adjustment. Then, based on the width of the sheet, the dual-head motor 405 is started to drive the screw 406 to rotate, causing the two sets of moving blocks 407 to move under the thread action of the screw 406. This adjusts the two sets of positioning plates 5 to move closer or further apart. Finally, based on the thickness of the sheet, the hydraulic rod 409 is retracted until the positioning plates 5 abut against the top surface of the sheet. The four sets of positioning plates 5 fix the four corners of the sheet. The hydraulic cylinder 6 extends to push the ring frame 7 downward, and then the electric cutter 12 is started to cut the metal sheet. At this time, the pressure roller 16 strengthens and fixes the cutting area of the metal sheet, and the two sets of springs 14 effectively absorb vibration and improve the cutting accuracy of the metal sheet. At the same time, the reciprocating motor 8 is started to drive the screw 9 to rotate, so that the moving sleeve 10 drives the electric cutter 12 to move and cut the metal sheet. When the moving sleeve 10 moves, it drives the connecting plate 13 to move in conjunction, so that the pressure roller 16 moves synchronously with the electric cutter 12, effectively absorbing vibration in the cutting area of the metal sheet.
