Description

Technical Field

[0001] This invention relates to the field of metal sheet production, and more particularly to a leveling device for metal sheets. Background Technology

[0002] Metal sheet leveling is a crucial process in metal processing, primarily used to eliminate shape defects such as wavy edges, warping, bending, and twisting that occur during rolling, transportation, storage, or subsequent processing. It improves the geometric accuracy (straightness and flatness) of the sheet metal, eliminates internal stress, and prevents deformation during subsequent processing (such as stamping, shearing, and laser cutting), ensuring it meets the required straightness and flatness standards. Current technology typically uses roll leveling machines for surface leveling. However, when roll leveling thin sheets, the relatively weak overall rigidity of a single sheet makes it prone to instability and wrinkling, thus reducing the leveling quality. Summary of the Invention

[0003] In order to overcome the shortcomings of existing thin plate straightening technology, which is prone to instability and wrinkling due to insufficient rigidity, thus affecting the straightening quality, this invention provides a straightening device for metal plates.

[0004] Technical Solution: A leveling device for metal sheets includes a leveling machine, mounting platforms, and electric conveyors connected to the corresponding mounting platforms; two mounting platforms are fixedly connected to the leveling machine; it also includes electric guide rails; two rectangular slots are formed on the leveling machine; an electric guide rail is installed in each rectangular slot; a moving block is slidably connected to each electric guide rail; a connecting plate is fixedly connected to each moving block; a fixing rod is fixedly connected to one of the connecting plates; the fixing rod has a slot; several spring balls are fixedly connected to the fixing rod, and the spring balls are located in the slot; a rotating rod is rotatably connected to the other connecting plate, and a torsion spring is provided between the rotating rod and the connecting plate; a diaphragm is wound around the rotating rod; a round rod that can engage with the slot is connected to the free end of the diaphragm; two electric conveying rollers are rotatably connected to the leveling machine, and the electric conveying rollers are located above the electric conveyor; the leveling machine is connected to a limiting component for limiting the movement of the sheet body.

[0005] To further explain, the limiting assembly includes limiting plates and limiting rollers; the leveling machine is connected to several limiting plates located above the electric conveyor; each limiting plate is rotatably connected to several limiting rollers.

[0006] To further explain, the limit roller is set at an angle.

[0007] To further explain, the limiting assembly also includes an electric push rod I; the leveling machine is fixedly connected to several electric push rods I, and the telescopic ends of every two electric push rods I are each fixedly connected to a limiting plate.

[0008] To further explain, the surface of the limit roller is equipped with a rubber pad.

[0009] To further explain, the inner wall of the card slot has a rough surface.

[0010] To further explain, the diaphragm and the round rod are detachably connected, and the diaphragm is also detachably connected to the rotating rod.

[0011] To further clarify, the diaphragm is made of nylon.

[0012] Further explanation: It also includes an electric push rod II; the leveling machine is rotatably connected to two electric push rods II; the telescopic ends of the two electric push rods II are jointly fixed to a support rod; the leveling machine is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to one of the electric push rods II.

[0013] To further explain, the surface of the support rod is provided with a protective layer.

[0014] The beneficial effects of the present invention are as follows: The present invention improves the overall rigidity by stacking two relatively thin plates, avoiding instability and wrinkling of a single thin plate during individual straightening, thereby improving the straightening efficiency; at the same time, the diaphragm between the two plates can effectively protect the surface of the plates, prevent additional wear caused by mutual compression during the stacking process, and ensure the surface quality of the plates after straightening.

[0015] By controlling the motor, its output shaft drives the electric push rod II and the support rod to slowly rotate downwards; at the same time, the electric push rod II is controlled to extend and retract, so that the support rod drives the other end of the second plate body to descend smoothly until it is completely attached to the diaphragm surface. This process can gradually squeeze out the air between the plate and the diaphragm, ensuring that the diaphragm is evenly and tightly attached between the two plates. Attached Figure Description

Detailed Implementation

[0018] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] Example 1: A leveling device for metal sheets, such as... Figures 1-5 As shown, it includes a leveling machine 1 and mounting platforms 2; the leveling machine 1 is fixedly connected to two mounting platforms 2; each mounting platform 2 is connected to an electric conveyor 3; It also includes an electric guide rail 101, a moving block 102, a connecting plate 103, a fixing rod 104, a spring ball 105, a rotating rod 106, a diaphragm 107, a round rod 108, an electric conveying roller 109, and a limiting assembly; the leveling machine 1 has two rectangular slots 11; each rectangular slot 11 is bolted to an electric guide rail 101; a moving block 102 is slidably connected to each electric guide rail 101; a connecting plate 103 is fixedly connected to each moving block 102; one of the connecting plates 103 is fixedly connected to a fixing rod 104; the fixing rod 104 is open A slot 41 is provided; eight spring balls 105 are fixedly connected to a fixing rod 104, and the spring balls 105 are located in the slot 41; another connecting plate 103 is rotatably connected to a rotating rod 106, and a torsion spring is provided between the rotating rod 106 and the connecting plate 103; a diaphragm 107 is wound around the rotating rod 106; a round rod 108 is connected to the free end of the diaphragm 107, and the round rod 108 can engage with the slot 41; two electric conveying rollers 109 are rotatably connected to the leveling machine 1, and the electric conveying rollers 109 are located above the electric conveyor 3; the leveling machine 1 is connected to a limit assembly.

[0020] The limiting assembly includes a limiting plate 1011 and a limiting roller 1012; the leveling machine 1 is connected to several limiting plates 1011, and the limiting plates 1011 are located above the electric conveyor 3; each limiting plate 1011 is rotatably connected to several limiting rollers 1012.

[0021] The limiting roller 1012 is inclined and provides additional downward pressure when the limiting roller 1012 limits the plate body 4, thereby enhancing the limiting effect on the plate body 4.

[0022] The limiting assembly also includes an electric push rod I1010; the leveling machine 1 is fixedly connected to several electric push rods I1010, and the telescopic ends of every two electric push rods I1010 are each fixedly connected to a limiting plate 1011.

[0023] The surface of the limiting roller 1012 is provided with a rubber pad.

[0024] The inner wall of the slot 41 is roughened to increase the friction between the slot 41 and the round rod 108, thereby improving the fixing effect of the slot 41 on the round rod 108.

[0025] The diaphragm 107 and the round rod 108 are detachably connected, and the diaphragm 107 is detachably connected to the rotating rod 106.

[0026] The diaphragm 107 is made of nylon, which has high tensile strength and tear resistance, and is not easily torn by high pressure and friction.

[0027] To face Figure 1 Based on the perspective, the operator first places the first board body 4 on the electric conveyor 3 on the right. Then, the diaphragm 107 is pulled horizontally backward from the rotating rod 106 by the round rod 108. At this time, the rotating rod 106 rotates relative to its corresponding connecting plate 103 and compresses the torsion spring on it. After the diaphragm 107 completely covers the upper surface of the first board body 4, the operator inserts the round rod 108 into the slot 41 of the fixing rod 104. The round rod 108 is limited and fixed by the elastic force of the spring ball 105. At this time, under the restoring force of the torsion spring of the rotating rod 106, the diaphragm 107 remains taut and straight to avoid wrinkles caused by the diaphragm 107 due to loosening during the subsequent feeding of the two board bodies 4 and the diaphragm 107 into the leveling machine 1.

[0028] Next, the second sheet body 4 is manually aligned and placed on the upper surface of the diaphragm 107. Then, the electric conveyor 3 is started, which drives the lower sheet body 4 to the right and enters the leveling machine 1. At the same time, the electric conveyor roller 109 is controlled to rotate, driving the upper sheet body 4 to be conveyed to the right synchronously. During this process, the electric guide rail 101 is controlled to drive the moving block 102, connecting plate 103, fixing rod 104, rotating rod 106, diaphragm 107 and round rod 108 to move to the right synchronously. This allows the diaphragm 107 and the two sheets to remain relatively stationary and enter the leveling machine 1 together for roller pressing and leveling. This leveling method improves the overall rigidity by stacking two thinner sheet bodies 4, avoiding instability and wrinkling of a single thin sheet during individual leveling, thereby improving leveling efficiency. At the same time, the diaphragm 107 between the two sheets can effectively protect the surface of the sheet, preventing additional wear caused by mutual compression during the stacking process, and ensuring the surface quality of the sheet after leveling.

[0029] When the two plates 4 are fed into the leveling machine 1 by the electric conveyor 3 and the electric conveying roller 109, their edges will contact the limiting roller 1012 and drive the limiting roller 1012 to rotate by friction. The limiting roller 1012 can guide and limit the edges of the plates 4 so that the two are always aligned and avoid deviation during the conveying process.

[0030] For different sizes of sheet body 4, the electric push rod I 1010 can be controlled to drive the corresponding limiting plate 1011 and limiting roller 1012 to adjust their positions back and forth, thereby adapting to sheet body 4 of different widths.

[0031] The surface of the limiting roller 1012 is covered with a rubber pad, which can reduce friction with the edge of the plate body 4 when making limiting contact, thus protecting the edge of the plate body 4.

[0032] Because the diaphragm 107 will wear down after long-term use, affecting its protective effect, it needs to be manually removed and replaced from the rotating rod 106 and the round rod 108 regularly to maintain its protective performance.

[0033] Example 2, based on Example 1, such as Figure 2 As shown, it also includes an electric push rod II 1013, a support rod 1014, and a motor 1015; the leveling machine 1 is rotatably connected to two electric push rods II 1013; the telescopic ends of the two electric push rods II 1013 are jointly fixed to the support rod 1014; the leveling machine 1 is bolted to the motor 1015, and the output shaft of the motor 1015 is fixed to one of the electric push rods II 1013.

[0034] The surface of the support rod 1014 is provided with a sponge layer.

[0035] Considering that when the second board body 4 is placed vertically downwards on the upper surface of the diaphragm 107, the air between the two cannot be discharged in time, which may cause residual air between the board body 4 and the diaphragm 107 and affect the bonding effect, in order to solve this problem, when placing the second board body 4, one end of it can be aligned with the edge of the first board body 4 below and in contact with the diaphragm 107, and then the other end of the board body 4 can be placed on the support rod 1014, so that the board is in an inclined state.

[0036] Next, the motor 1015 is started, and its output shaft drives the electric push rod II 1013 and the support rod 1014 to slowly rotate downwards; at the same time, the electric push rod II 1013 is controlled to extend and retract, so that the support rod 1014 drives the other end of the second plate body 4 to descend smoothly until it is completely attached to the surface of the diaphragm 107. This process can gradually squeeze out the air between the plate body 4 and the diaphragm 107, ensuring that the diaphragm 107 is evenly and tightly attached between the two plates.

[0037] In addition, the surface of the support rod 1014 is covered with a sponge layer, which can increase the friction between the support rod and the board body 4 to prevent the board body 4 from sliding after placement; on the other hand, it also plays a buffering and protective role to prevent the support rod 1014 from directly contacting and scratching the surface of the board body 4.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
