Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet cutting and correction equipment, specifically a correction device for cutting metal sheets. Background Technology

[0002] Metal sheet cutting is a process that uses shearing, stamping, laser cutting, and other techniques to process metal sheets into specific sizes and shapes. It is widely used in the automotive, machinery manufacturing, and construction industries and is a fundamental step in metal processing. The correction device used in metal sheet cutting adjusts the position of the sheet in real time by driving an actuator when the sheet's position deviates during the cutting process. This ensures that the cutting path always precisely matches the preset trajectory, thereby avoiding problems such as out-of-tolerance cutting dimensions, skewed cuts, and excessive waste edges. It guarantees the accuracy of the cut parts, reduces material waste, and maintains the stability of the cutting process to improve production efficiency.

[0003] For example, a metal sheet cutting correction device disclosed in Chinese patent literature (publication number: CN221210137U) uses a drive mechanism at the bottom of the base plate to drive the housing to move in opposite directions along the slide groove. The rollers inside the housing, together with the moving block and the opening groove, can contact the metal sheet. At this time, the rollers can move the metal sheet along the center line of the base plate. The correction mechanism corrects the metal sheet to prevent it from deviating, ensuring the cutting accuracy of the sheet cutting mechanism and improving the pass rate of the cut metal sheet. At the same time, a hydraulic cylinder is provided on the base plate, which can work with the push plate to push the metal sheet along the rollers towards the sheet cutting mechanism, avoiding contact between the workers and the sheet cutting mechanism and preventing injury to the workers.

[0004] However, this device relies on metal rollers and fixed-stroke springs to squeeze and correct the edges of the sheet material, which has two major drawbacks: First, the spring stroke is fixed, and thin sheets are not tightly adhered, which can easily lead to correction failure; thick sheets are squeezed and deformed, which can easily lead to edge damage. Second, the metal rollers make hard contact with the sheet material, which can easily scratch the surface. Utility Model Content

[0005] The purpose of this utility model is to provide a correction device for cutting metal sheets in order to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal sheet cutting correction device, comprising: an operating table, correction mechanisms provided at the upper ends of both sides of the operating table, a support frame fixedly connected above the operating table, a cylinder fixedly connected in the middle of the support frame, a cutting component fixedly connected to the movable end of the cylinder, a through groove opened at one end inside the operating table, a support roller rotatably connected inside the through groove, and a feeding mechanism provided at the bottom and top of the operating table.

[0007] As a further embodiment of this utility model: the correction mechanism includes a double-slide rail gantry frame, a second cylinder, and a support base. The double-slide rail gantry frame is fixedly connected to the upper ends of both sides of the operating table, and the second cylinder is fixedly connected to the upper end of the middle part of one side of the double-slide rail gantry frame; a drive chamber, a rotating shaft, and a pulley. The drive chamber is fixedly connected to the bottom of the support base, the rotating shaft is rotatably connected to the inner side of the support base, and the pulley is fixedly connected to the middle end of the outer side of the rotating shaft; a motor, a lead screw, and an adsorption assembly. The motor is fixedly connected to one end of the drive chamber, the lead screw is rotatably connected to the inner side of the drive chamber, and the adsorption assembly is located below the drive chamber.

[0008] As a further embodiment of this utility model: the adsorption assembly includes a slider, a movable frame, and an electric push rod. The slider is slidably connected inside the drive chamber, and the slider is threadedly connected to a lead screw. The movable frame is fixedly connected below the slider, and the electric push rod is fixedly connected to the middle of the movable frame. An extension plate, a bracket, and a suction cup are also included. The extension plate is vertically slidably connected to the lower part of the movable frame, the bracket is fixedly connected below the extension plate, the suction cup is fixedly connected to the middle of the bracket, and the movable end of the electric push rod is fixedly connected to the bracket.

[0009] As a further embodiment of this utility model: the feeding mechanism includes a second motor and a second lead screw. The second motor is fixedly connected to one end of the bottom of the operating table, the second lead screw is fixedly connected to the output end of the second motor, and the other end of the second lead screw is rotatably connected to the operating table; a movable ejector and a feeding pusher are also included. The movable ejector is threadedly connected to one end of the outer side of the second lead screw, and the movable ejector is slidably connected to the operating table. The movable ejector extends to the top of the operating table, and the feeding pusher is fixedly connected to the portion of the movable ejector that extends to the top of the operating table.

[0010] As a further improvement of this utility model: both the correction mechanism and the through slot are provided in two sets. The two sets of correction mechanisms are horizontally symmetrically arranged on both sides of the operating table, and the two sets of through slots are symmetrically arranged inside the operating table. Each set of through slots is symmetrically provided with multiple sets of support rollers inside.

[0011] As a further embodiment of this utility model: the movable end of the second cylinder is fixedly connected to the drive chamber, the pulley and the double slide rail gantry are tumblingly connected, and the other end of the first lead screw passes through the drive chamber and is fixedly connected to the output end of the first motor.

[0012] As a further embodiment of this utility model: the number of cylinder two, the number of drive chamber, the number of motor one, the number of lead screw one and the number of adsorption components are all provided in two sets, and the number of support base, the number of rotating shaft and the number of pulley are all provided in four sets, with each set of drive chamber connected to two sets of support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the sheet material is first placed on the operating table, with support rollers assisting in support and movement. The feeding mechanism is then activated, and motor two drives screw two to rotate, causing the moving frame to move horizontally with the feeding push plate, pushing the sheet material towards the cutting assembly. This not only achieves automatic feeding but also allows the push plate to contact the edge of the sheet material, initially aligning the sheet material during transport, reducing initial placement deviations, and laying the foundation for subsequent precise correction and cutting accuracy. When the sheet material reaches the correction mechanism area, the correction mechanism is activated: cylinder two drives the drive chamber, which moves smoothly on the double-rail gantry frame with the help of pulleys on the support base, adapting to sheets of different widths. The electric push rod pushes the bracket and extension plate downwards, allowing suction cups to adhere to both sides of the sheet material. A total of four sets of suction components on both sides work together to precisely correct the sheet material to the correct cutting position, ensuring the stability of the sheet material during cutting. This method is also suitable for sheets of different thicknesses. Compared with mechanical clamping, it relies on suction force for fine adjustment without hard squeezing, which can protect the surface and edges of the sheet material to the greatest extent and reduce the scrap rate.

The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 6 In this embodiment of the utility model, a metal sheet cutting correction device includes: an operating table 1, which serves as the basic support platform of the device, for placing the metal sheet to be cut, and also provides installation support for multiple mechanisms and components. It is the core operating area of ​​the entire cutting operation. Correction mechanisms 2 are provided on the upper ends of both sides of the operating table 1, and their core function is to correct the position of the metal sheet being transported.

[0019] A support frame 3 is fixedly connected above the operating table 1. A cylinder 4 is fixedly connected in the middle of the support frame 3. A cutting component 5 is fixedly connected to the movable end of the cylinder 4. The cylinder 4 is fixedly installed through the support frame 3.

[0020] The operating table 1 has a through groove 6 at one end, and a support roller 7 is rotatably connected inside the through groove 6. The through groove 6 provides installation space for the support roller 7, which supports the metal plate on the operating table 1, reduces the friction between the plate and the operating table 1, and can roll with the plate during the plate conveying to help the plate move smoothly.

[0021] The bottom and top of the operating table 1 are equipped with a feeding mechanism 8, which is responsible for conveying the metal sheet to be cut to the cutting component 5. There are two sets of correction mechanism 2 and through groove 6. The two sets of correction mechanism 2 are horizontally symmetrically arranged on both sides of the operating table 1, and the two sets of through groove 6 are symmetrically arranged inside the operating table 1. Each set of through groove 6 is symmetrically equipped with multiple sets of support rollers 7.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The correction mechanism 2 includes a double slide rail gantry 21, a second cylinder 22 and a support base 23. The double slide rail gantry 21 is fixedly connected to the upper ends of both sides of the operating table 1, and the second cylinder 22 is fixedly connected to the upper end of the middle part of one side of the double slide rail gantry 21. The drive chamber 24, the rotating shaft 25, and the pulley 26 are fixedly connected to the bottom of the support base 23, the rotating shaft 25 is rotatably connected to the inner side of the support base 23, and the pulley 26 is fixedly connected to the middle of the outer side of the rotating shaft 25. Motor 27, lead screw 28, and adsorption assembly 29 are provided. Motor 27 is fixedly connected to one end of the drive chamber 24. Lead screw 28 is rotatably connected to the inside of the drive chamber 24. Adsorption assembly 29 is located below the drive chamber 24. The movable end of cylinder 22 is fixedly connected to drive chamber 24, pulley 26 is rolledly connected to double slide rail gantry 21, and the other end of screw 28 passes through drive chamber 24 and is fixedly connected to the output end of motor 27. There are two sets of cylinder 22, drive chamber 24, motor 27, lead screw 28 and adsorption assembly 29, and four sets of support base 23, rotating shaft 25 and pulley 26. Each set of drive chamber 24 is connected to two sets of support base 23.

[0023] The adsorption assembly 29 includes a slider 291, a movable frame 292, and an electric push rod 293. The slider 291 is slidably connected to the inside of the drive chamber 24. The slider 291 is threadedly connected to the lead screw 28. The movable frame 292 is fixedly connected to the bottom of the slider 291. The electric push rod 293 is fixedly connected to the middle of the inside of the movable frame 292. The extension plate 294, bracket 295, and suction cup 296 are arranged in a vertical sliding connection. The extension plate 294 is vertically slidably connected to the lower part of the movable frame 292. The bracket 295 is fixedly connected to the lower part of the extension plate 294. The suction cup 296 is fixedly connected to the middle part of the bracket 295. The movable end of the electric push rod 293 is fixedly connected to the bracket 295. When the metal sheet is conveyed to the working area of ​​the correction mechanism 2, the cylinder 22 extends and retracts to drive the long chamber 24 to move. The support base 23 rolls on the double slide rail gantry frame 21 through the pulley 26 on the rotating shaft 25 to realize the smooth movement of the long chamber 24 to adapt to the sheet of different widths. The electric push rod 293 extends and pushes the bracket 295 to move down. The extension plate 294 moves down with it until the suction cup 296 contacts the two sides of the metal sheet and adsorbs the sheet. Through the coordinated action of four sets of adsorption components 29 on both sides, the metal sheet is precisely corrected to ensure that it is in the correct cutting position. This also maintains the stability of the metal sheet during cutting. This method is suitable for metal sheets of different thicknesses. Compared with mechanical clamping correction, the adsorption force drives the sheet to make fine adjustments without hard squeezing, which can protect the surface quality and edge integrity of the sheet to the greatest extent.

[0024] Reference Figure 1 , Figure 2 and Figure 6 The feeding mechanism 8 includes a second motor 81 and a second lead screw 82. The second motor 81 is fixedly connected to one end of the bottom of the operating table 1, and the second lead screw 82 is fixedly connected to the output end of the second motor 81. The other end of the second lead screw 82 is rotatably connected to the operating table 1. The movable ejector 83 and the feeding pusher 84 are configured. The movable ejector 83 is threaded to one end of the lead screw 82 and is slidably connected to the operating table 1. Part of the movable ejector 83 extends above the operating table 1. The feeding pusher 84 is fixedly connected to the part of the movable ejector 83 that extends above the operating table 1. The lead screw 82 is driven to rotate by the motor 81, which causes the movable ejector 83, which is threaded to the lead screw 82, to move the feeding pusher 84 horizontally along the operating table 1. This pushes the metal sheet on the support roller 7 towards the cutting assembly 5. This not only serves the purpose of feeding, but also allows the feeding pusher 84 to directly contact and push the edge of the metal sheet. During the feeding process, the metal sheet can be initially aligned, reducing the impact of the initial placement deviation of the metal sheet on subsequent cutting.

[0025] The working principle of this utility model is as follows: When cutting metal sheets, the metal sheet to be processed is first placed on the operating table 1. The support roller 7 supports the sheet and assists in its movement. The feeding mechanism 8 is started, and the motor 81 drives the lead screw 82 to rotate. This causes the moving frame 83, which is threaded onto the lead screw 82, to move the feeding pusher plate 84 horizontally along the operating table 1, thereby pushing the metal sheet on the support roller 7 towards the cutting assembly 5. This not only serves the purpose of feeding, but also allows the feeding pusher plate 84 to directly contact and push the edge of the metal sheet. During the feeding process, the metal sheet can be initially aligned, reducing the impact of the initial placement deviation on subsequent cutting. This is equivalent to reducing the burden in advance for subsequent precise correction, thus improving the overall cutting accuracy. When the metal sheet is conveyed to the working area of ​​the correction mechanism 2, the correction mechanism 2 starts to operate. The cylinder 22 extends and retracts, driving the drive chamber 24 to move. The support base 23 rolls on the double slide rail gantry 21 via the pulley 26 on the rotating shaft 25, realizing the smooth movement of the drive chamber 24 to accommodate sheets of different widths. The electric push rod 293 extends and pushes the bracket 295 downward, and the extension plate 294 moves downward accordingly until the suction cup 296 contacts and adsorbs the sheet on both sides. Through the coordinated action of four sets of adsorption components 29 on both sides, the metal sheet is precisely corrected to ensure that the metal sheet is in the correct cutting position. This also maintains the stability of the metal sheet during cutting. This method is suitable for metal sheets of different thicknesses. Compared with mechanical clamping correction, the adsorption force drives the sheet to make fine adjustments without hard compression, which can protect the surface quality and edge integrity of the sheet to the greatest extent and reduce the scrap rate.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
