Technical Field
[0001] This utility model belongs to the field of sheet metal processing technology, and specifically relates to a leveling and calibration device for sheet metal processing. Background Technology
[0002] Leveling equipment for sheet metal processing is used to level sheet metal parts during the processing, ensuring the flatness of the sheet metal parts and improving their processing quality.
[0003] A search revealed that application number "CN202223382509.6" discloses "a leveling device for sheet metal processing," which describes that "the leveling box of the utility model has three sets of pressure rollers inside, which can perform roll pressing on the sheet metal parts fed into the leveling box. The roll pressing process can be moved and pressed, and the upper and lower end faces of the sheet metal parts can be pressed simultaneously. Combined with the stamping and pressing mechanisms at both ends of the leveling box, the final flatness of the sheet metal parts after pressing is high." While the utility model's leveling box with three sets of pressure rollers can indeed perform roll pressing on the sheet metal parts fed into the leveling box, and the roll pressing process can be moved and pressed, thus simultaneously pressing the upper and lower end faces of the sheet metal parts, and combined with the stamping and pressing mechanisms at both ends of the leveling box, resulting in a high flatness of the final flatness of the sheet metal parts, the above-mentioned documents still have the following problems in actual use:
[0004] In practical use, the lack of intelligent leveling and calibration results in poor accuracy. It is also inconvenient to process sheet metal of different lengths and to replace the calibration plate to adapt to sheet metal of different shapes.
[0005] Based on this, a device that can intelligently level and calibrate, can be adjusted to process sheet metal of different lengths, and can replace the calibration plate to adapt to sheet metal of different shapes is highly practical. Utility Model Content

A synchronous motor is installed at one end of the inner wall of each of the two movable boxes. Gears are installed through the output shafts of the two synchronous motors, and racks mesh with the bottoms of the two gears. The bottom of the racks is fixedly connected to the bottom of the inner wall of the base. An auxiliary block is installed at one end of each of the two movable boxes. Limit rods are slidably connected inside the two auxiliary blocks. The two sides of the limit rods are fixedly connected to the base. Several support heads are installed on the top of each of the two movable boxes. The outer walls of the support heads are slidably connected to a sliding groove. Two bases are installed on the top of the support heads. The top of the bases is movably connected to a calibration plate. Two locking plates are provided on one side of the bottom, and two locking slots are opened at one end of each of the two locking plates. Several fixing plates are provided on one side of the base, and two electric telescopic rods are installed inside the fixing plates. Reinforcing plates are provided at the ends of the two electric telescopic rods, and two first hinge seats are provided at the ends of the reinforcing plates. Connecting rods are hinged inside the two first hinge seats. Second hinge seats are hinged in the middle of the two connecting rods. Connecting frames are provided at one end of the two second hinge seats. The interior of the connecting frames is movably connected to the locking plates. Two beveled plugs are provided at one end of the connecting rods. The ends of the two beveled plugs are inserted and connected to the two locking slots. The other side of the locking plates and the base has the same structure.
[0011] In one embodiment of this utility model, a torque motor is provided on one side of one of the support bars, and a lead screw is provided at the output shaft end of the torque motor. A moving block is threadedly connected to the outer wall of the lead screw, and two moving pieces are provided at one end of the moving block. One end of each of the two moving pieces is fixedly connected to the moving frame.
[0012] In one embodiment of this utility model, the base is made of chromium metal.
[0013] In one embodiment of this utility model, both bases, the calibration plate, and the moving box are all made of tungsten metal.
[0014] In one embodiment of this utility model, the outer wall of the calibration plate is coated with a wear-resistant coating.
[0015] In one embodiment of this utility model, the pressure head is cast from titanium alloy.
[0016] In one embodiment of this utility model, the hydraulic cylinder, laser sensor, synchronous motor, electric telescopic rod, and torque motor are all electrically connected to the programmable controller, which is electrically connected to an external power supply.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1) Using the laser sensor, the user first presets the ideal leveling value through the programmable controller. Then, the user turns on the laser sensor through the programmable controller and places the sheet metal on the calibration plate. At this time, the programmable controller detects the degree of curvature of the sheet metal. The curvature information detected by the laser sensor is transmitted to the programmable controller in real time. The programmable controller calculates the difference between the current curvature and the ideal flatness state, which is the amount of curvature that needs to be corrected. Based on the calculated pressure value, the programmable controller controls the output of the oil pump in the hydraulic cylinder, and then controls the output force of the hydraulic cylinder so that its output shaft extends, driving the lower pressure head to apply pressure to the sheet metal. During the leveling process, the programmable controller continuously adjusts the output force of the hydraulic cylinder based on the real-time feedback of the data sent by the laser sensor to ensure that the leveling effect reaches the best. When the laser sensor detects that the sheet metal has reached the preset leveling value, it will stop, thereby achieving the purpose of intelligent calibration.
[0019] 2) With the included synchronous motor, users can easily adjust the distance between the two calibration plates to accommodate sheet metal of different lengths. By using the programmable controller, the user can start the synchronous motors simultaneously, which will drive the gears to rotate. The rotation of the gears will move on the rack, which in turn will drive the synchronous motors to move the moving boxes and the top parts, causing the two moving boxes and their top parts to move closer to the center or outward. This will then cause the calibration plates to move closer to the center or outward, thus achieving the adjustment of the distance between the two calibration plates.
[0020] 3) Furthermore, during prolonged use, when the calibration plate needs to support sheet metal with special shapes, such as cylindrical shapes, the user can open the electric telescopic rod through the programmable controller. This telescopic rod unfolds, causing the reinforcing plate to move. The movement of the reinforcing plate will cause the two first hinge seats to move, which in turn will cause the connecting rod to move through the second hinge seat. This will cause the angled plug to slide out of the slot, releasing the limit on the card plate and thus the limit on the calibration plate. This allows the user to remove the calibration plate and replace it with a special shape to support sheet metal with a special shape, thereby achieving the purpose of adjustment and replacement and improving its versatility during use.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Example
[0029] Please see Figure 1-4 A leveling and calibration device for sheet metal processing includes a base 100, an intelligent calibration component 200, and an adjustment and replacement component 300.
[0030] Please refer to the details. Figure 1 The top of the base 100 has two sliding grooves and two support bars 110.
[0031] Please see Figure 1 The intelligent calibration component 200 includes a connecting box 210 disposed between two support bars 110. Two auxiliary slots are provided at one end of the connecting box 210. Limiting plates 220 are provided at the top and bottom of the connecting box 210. A movable frame 230 is slidably connected to the two limiting plates 220 and the outer wall of the connecting box 210. A hydraulic cylinder 240 is provided inside the movable frame 230. The output shaft end of the hydraulic cylinder 240 passes through the movable frame 230 and is provided with a pressing head 250. A support plate 260 is provided at one end of the top of the base 100. Several laser sensors 270 are provided at one end of the support plate 260. A programmable controller 280 is provided at one end of one of the support bars 110. Two calibration plates 290 are provided at the bottom of the connecting box 210.
[0032] In one specific embodiment, using the provided laser sensor 270, the user first presets the ideal leveling value through the programmable controller 280. Then, the user activates the laser sensor 270 through the programmable controller 280 and places the sheet metal on the calibration plate 290. The programmable controller 280 detects the degree of curvature of the sheet metal. The curvature information detected by the laser sensor 270 is transmitted to the programmable controller 280 in real time. The difference between the current curvature and the ideal flatness is calculated, representing the amount of curvature that needs correction. Based on the calculated pressure value, the programmable controller 280 controls the output of the oil pump inside the hydraulic cylinder 240, thereby controlling the output force of the hydraulic cylinder 240. The hydraulic cylinder 240 extends its output shaft, driving the lower pressure head 250 to apply pressure to the sheet metal. During the leveling process, the programmable controller 280 continuously adjusts the output force of the hydraulic cylinder 240 based on real-time feedback from the laser sensor 270 to ensure optimal leveling results. When the laser sensor 270 detects that the sheet metal has reached the preset leveling value, it will stop, thus achieving intelligent calibration.
[0033] Please see Figure 3-4The adjustment and replacement component 300 includes two movable boxes 310 slidably connected to the bottom of the inner wall of the base 100. A synchronous motor 320 is installed at one end of the inner wall of each of the two movable boxes 310. Gears 330 are installed through the output shafts of the two synchronous motors 320 and pass through the movable boxes 310. A rack 340 meshes with the bottom of the two gears 330, and the bottom of the rack 340 is fixedly connected to the bottom of the inner wall of the base 100. An auxiliary block 350 is installed at one end of each of the two movable boxes 310. A limit rod 360 is slidably connected inside the two auxiliary blocks 350. The two sides of the limit rod 360 are fixedly connected to the base 100. Several support heads 370 are installed on the top of each of the two movable boxes 310. The outer walls of the support heads 370 are slidably connected to a sliding groove. Two bases 380 are installed on the top of the support heads 370. The top of the bases 380 is movably connected to a calibration plate 290. A bottom side of the calibration plate 290 is provided with... The base 380 has two locking plates 390, each with two slots at one end. A number of fixing plates 3910 are located on one side of the base 380. Two electric telescopic rods 3920 are installed inside the fixing plates 3910. Each electric telescopic rod 3920 has a reinforcing plate 3930 at its end. Each reinforcing plate 3930 has two first hinge seats 3940 at its end. Each first hinge seat 3940 has a connecting rod 3950 hinged inside. Each connecting rod 3950 has a second hinge seat 3960 hinged in the middle. Each second hinge seat 3960 has a connecting frame 3970 at one end, which is movably connected to the locking plate 390. Each connecting rod 3950 has two angled plugs 3980 at one end, each end of which is inserted into one of the slots. The other side of the locking plate 390 and the base 380 has the same structure.
[0034] In one specific embodiment, the included synchronous motor 320 allows the user to easily adjust the distance between the two calibration plates 290 to accommodate sheet metal of varying lengths. The user activates the synchronous motor 320 via the programmable controller 280, causing both motors to start simultaneously and drive the gear 330 to rotate. The rotating gear 330 moves along the rack 340, which in turn moves the synchronous motor 320, causing the moving boxes 310 to move. This allows the two moving boxes 310 and their top parts to move closer together or outwards, thereby adjusting the distance between the two calibration plates 290. Furthermore, during prolonged use, the calibration plates 290 may require partial reshaping. When supporting sheet metal with special shapes, such as cylindrical shapes, the user can open the electric telescopic rod 3920 through the programmable controller 280, causing the electric telescopic rod 3920 to unfold. This will then move the reinforcing plate 3930, which in turn will move the two first hinge seats 3940. The movement of the first hinge seats 3940 will cause the connecting rod 3950 to move through the second hinge seat 3960, which will then cause the inclined plug 3980 to slide out of the slot, releasing the limit on the card plate 390 and subsequently releasing the limit on the calibration plate 290. This allows the user to remove the calibration plate 290 and replace it with a special shape to support sheet metal of a different shape, thereby achieving the purpose of adjustment and replacement and improving the versatility of use.
[0035] Please see Figure 2 One of the support bars 110 is equipped with a torque motor 400 on one side. The output shaft end of the torque motor 400 is equipped with a lead screw 500. The outer wall of the lead screw 500 is threaded with a moving block 600. One end of the moving block 600 is equipped with two moving pieces 700. One end of each of the two moving pieces 700 is fixedly connected to the moving frame 230.
[0036] In one specific embodiment, the torque motor 400 is conveniently activated by the programmable controller 280 during use. The torque motor 400 drives the lead screw 500 to rotate. The lead screw 500 engages with the connecting box 210 through its external thread, causing the moving block 600 to move the moving piece 700 within the connecting box 210. This, in turn, causes the moving piece 700 to move the moving frame 230, which then moves outside the connecting box 210. This movement also drives the hydraulic cylinder 240 and its internal bottom components, allowing the machine to be moved to various positions on the sheet metal and straightened during leveling, thus improving work efficiency.
[0037] Please see Figure 1 The base 100 is made of chromium metal.
[0038] In one specific embodiment, the presence of chromium metal allows the base 100 to be made more robust and stable during use by taking advantage of the durable properties of chromium.
[0039] Please see Figure 1-4 The two bases 380, the calibration plate 290 and the moving box 310 are all made of tungsten metal.
[0040] In one specific embodiment, the presence of tungsten metal facilitates the use of the base 380, calibration plate 290, and moving box 310, making them more durable by utilizing the robust and durable properties of tungsten.
[0041] Please see Figure 1 The outer wall of calibration plate 290 is coated with a wear-resistant coating.
[0042] In one specific embodiment, the wear-resistant coating effectively reduces the wear of the calibration plate 290 when it is used, thereby extending the service life of the calibration plate 290.
[0043] Please see Figure 1 The pressure head 250 is made of titanium alloy.
[0044] In one specific embodiment, the titanium alloy provided allows the pressure head 250 to be more stable during use by taking advantage of its robust and durable properties when straightening sheet metal.
[0045] Please see Figure 1-4 The hydraulic cylinder 240, laser sensor 270, synchronous motor 320, electric telescopic rod 3920 and torque motor 400 are all electrically connected to the programmable controller 280, which is electrically connected to an external power supply.
[0046] In one specific embodiment, a programmable controller 280 is provided to facilitate power control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding the situation where power cannot be supplied when needed.
[0047] In use, the user first presets the ideal leveling value using the laser sensor 270 via the programmable controller 280. Then, the user activates the laser sensor 270 via the programmable controller 280 and places the sheet metal on the calibration plate 290. The programmable controller 280 then detects the degree of curvature of the sheet metal. The curvature information detected by the laser sensor 270 is transmitted to the programmable controller 280 in real time. The difference between the current curvature and the ideal leveling state is calculated, which is the amount of curvature that needs to be corrected. Based on the calculated pressure value, the programmable controller 280 controls the oil pump inside the hydraulic cylinder 240. The output of the hydraulic cylinder 240 is controlled, causing its output shaft to extend and drive the lower pressure head 250 to apply pressure to the sheet metal. During the leveling process, the programmable controller 280 continuously adjusts the output force of the hydraulic cylinder 240 based on real-time feedback from the laser sensor 270 to ensure optimal leveling results. When the laser sensor 270 detects that the sheet metal has reached the preset leveling value, it will stop, thus achieving intelligent calibration. Then, the included synchronous motor 320 allows users to easily adjust the distance between the two calibration plates 290 to accommodate sheet metal of different lengths. The operator activates the synchronous motors 320 via the programmable controller 280, causing both synchronous motors 320 to start simultaneously and drive the gear 330 to rotate. The rotation of the gear 330 moves the rack 340, which in turn causes the synchronous motors 320 to move the moving boxes 310, moving the two moving boxes 310 and their top parts towards the center or outwards. This, in turn, causes the calibration plate 290 to move towards the center or outwards, thus adjusting the distance between the two calibration plates 290. Furthermore, during prolonged use, when the calibration plate 290 needs support for specially shaped sheet metal, such as cylindrical pieces, the operator can use the programmable controller 280 to... 80. Open the electric telescopic rod 3920 to unfold it, which in turn moves the reinforcing plate 3930. Finally, the movement of the reinforcing plate 3930 will cause the two first hinge seats 3940 to move. The movement of the first hinge seats 3940 will cause the connecting rod 3950 to move through the second hinge seat 3960, which will then cause the inclined plug 3980 to slide out of the slot, releasing the limit on the card plate 390, and then releasing the limit on the calibration plate 290, so that the user can remove the calibration plate 290 and replace it with a special shape to support the special shape of the sheet metal, thereby achieving the purpose of adjustment and replacement, and improving the versatility of use.
[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
