Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to a processing device for rolling metal plates. Background Art

[0002] Metal sheet rolling refers to a processing method in which a metal blank is passed through the gap between a pair of rotating rollers using a rolling mill to cause it to undergo plastic deformation and obtain the desired size, shape and performance.

[0003] The existing devices of this type cause internal stress in the metal sheet after rolling due to the limitation of the rolling process. For example, a metal sheet rolling device disclosed in Chinese Patent Publication No. "CN114985452A" can only perform stress relief treatment on the metal sheet after rolling due to structural limitations. The existence of internal stress will reduce the strength of the material or induce cracks and fractures. The metal sheet itself has a certain residual temperature for a period of time after rolling. If stress relief treatment is performed at this time, it can promote the diffusion and recrystallization process inside the metal, which is helpful for stress release and smooth grain structure, thereby reducing the residual stress level. That is, stress removal can achieve better results when the metal is at high temperature. However, the device cannot perform the above operation, resulting in lower production efficiency. Accordingly, the present application proposes a processing device for metal sheet rolling. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a processing device for metal plate rolling.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A processing device for rolling metal sheets, comprising a rolling mechanism, a stress relief mechanism, and a cooling system. The rolling mechanism comprises a driven roller, an active roller, a motor, a lifting screw, a base, and a connecting beam. The driven roller is rotatably connected to the connecting beam, and the active roller is fixedly connected to the output shaft of the motor. When the motor is started, the metal sheet to be rolled passes between the driven roller and the active roller, and the stress relief mechanism and the cooling system also work simultaneously, thereby completing the rolling, stress relief, and cooling of the metal after rolling.

[0007] The stress relief mechanism includes a gland, a connecting block, a rotating disk, a connecting rod, a sliding rod, a lifting rod, a connecting frame, and a pressure roller. The pressure roller is used to relieve the internal stress of the metal sheet after rolling. The connecting frame is fixedly connected to the connecting block. Since the connecting block is fixedly connected to the lifting rod, and the connecting frame is fixedly connected to the connecting block, when the device is running, the connecting frame can move up and down, and drive the pressure roller to knock the metal sheet after rolling.

[0008] The piston is fixedly connected to the connecting block.

[0009] Preferably, the cooling system includes a heat conduction plate, a piston, a serpentine tube, a water outlet pipe, a No. 1 one-way valve, a No. 2 one-way valve, a water tank, a water inlet pipe, and a hose. The serpentine tube is fixedly arranged in the heat conduction plate. When the rolled metal sheet passes over the heat conduction plate, the heat is transferred from the heat conduction plate to the serpentine tube. At the same time, the piston will also start to pump the water in the water tank into the serpentine tube, and then flow into the water tank through the water inlet pipe.

[0010] Preferably, one end of the connecting beam is slidably connected to the base, and the other end is threadedly connected to the screw rod, a No. 2 bevel gear is fixedly connected to the screw rod, a rotating rod is rotatably connected to the side wall of the base, a No. 1 bevel gear is fixedly connected to the front end of the rotating rod, and the No. 1 bevel gear is meshed with the No. 2 bevel gear.

[0011] Preferably, the water inlet end of the No. 1 one-way valve is connected to the piston through a hose, the water outlet end of the No. 1 one-way valve is connected to the serpentine tube through a hose, the water inlet end of the No. 2 one-way valve is connected to the water tank through an inlet pipe, and the water outlet end of the No. 2 one-way valve is connected to the piston through an inlet pipe.

[0012] Preferably, the piston is fixedly connected to the pressure cover, the connecting frame is slidably connected to the pressure cover, the active roller is rotatably connected to the base, and the turntable is fixedly connected to the output shaft of the motor.

[0013] Preferably, resonance beads are arranged in the pressure roller, and a spring is fixedly connected above the resonance beads.

[0014] Preferably, the screw rod is rotatably connected to the base, and the gland and the water tank are both fixedly connected to the base.

[0015] Preferably, the connecting frame is fixedly connected to a plurality of pressure rollers, and the connecting block is fixedly connected to the lifting rod.

[0016] The present invention has the following beneficial effects:

[0017] 1. By setting a screw rod, the height of the driven roller in the device can be adjusted, so as to adapt to the processing of metal plates of different thicknesses.

[0018] 2. By setting up a stress relief mechanism, the internal stress generated by rolling can be eliminated after the metal sheet is rolled, so that the reliability of the metal sheet will not be reduced due to the internal stress.

[0019] 3. By setting up a cooling system, the rolled metal sheets can be cooled more quickly. Since the cooling time is saved, the production efficiency of the metal sheets is improved.

[0020] 4. By setting a turntable, a connecting rod, a sliding rod and a lifting rod, the stress relief mechanism and the cooling system can automatically start working when the device is working without manual operation, which facilitates the operation and reduces the labor intensity.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1:

[0031] Reference Figure 1 , Figure 6 , Figure 7, a processing device for rolling metal plates, comprising a rolling mechanism, a stress relief mechanism, and a cooling system;

[0032] refer to Figure 1 and Figure 6 The rolling mechanism includes a driven roller 5, an active roller 6, a motor 2, a lifting screw 4, a base 1, and a connecting beam 3. The driven roller 5 is rotatably connected to the connecting beam 3, and the active roller 6 is fixedly connected to the output shaft of the motor 2. When the motor 2 is started, the metal sheet to be rolled passes between the driven roller 5 and the active roller 6, and the stress relief mechanism and the cooling system also work at the same time, thereby completing the rolling, stress relief, and cooling of the metal after rolling.

[0033] In this embodiment, since the No. 1 bevel gear 8 and the No. 2 bevel gear 9 are meshed with each other, the No. 1 bevel gear 8 can be rotated to drive the lifting screw 4 to rotate and then drive the driven roller 5 to rise and fall. Because the thread has self-locking properties, when the driven roller 5 rises or falls to a certain position, it will stay at the current position. Therefore, this device can adapt to the processing of metal plates of different thicknesses.

[0034] Embodiment 2:

[0035] Furthermore, in this embodiment, the stress relief mechanism includes a pressure cover 10, a connecting block 15, a rotating disk 16, a connecting rod 17, a sliding rod 18, a lifting rod 19, a connecting frame 11, and a pressure roller 12. The pressure roller 12 is used to relieve the internal stress of the metal sheet after rolling. The connecting frame 11 is fixedly connected to the connecting block 15. Since the connecting block 15 is fixedly connected to the lifting rod 19, and the connecting frame 11 is fixedly connected to the connecting block 15, when the device is running, the connecting frame 11 can move up and down, and drive the pressure roller 12 to knock the metal sheet after rolling.

[0036] In this embodiment, the rotating disk 16 provides power for the piston 14 and the stress relief mechanism, and the connecting rod 17 is eccentrically fixed on the rotating disk 16. When the active roller 6 is working, the connecting rod 17 will also rotate and drive the connecting block lifting rod 19 to move up and down, which can provide power for the stress relief mechanism and the piston 14, so that the stress relief mechanism and the cooling system will also work synchronously when the device starts to work. The principle is that when the rotating disk 16 rotates, the angle and height of the connecting rod 17 are changed, and the height change of the connecting rod 17 will act on the lifting rod 19, that is, the height of the lifting rod 19 changes with the rotation of the rotating disk 16, and at the same time, the change in the angle of the connecting rod 17 will be reflected on the sliding rod 18, that is, with the rotation of the rotating disk 16, the sliding rod 18 will slide in the lifting rod 19, so as to offset the change in the angle of the connecting rod 17, and the change in the height of the connecting rod 17 is used by the lifting rod 19 to provide power for the stress relief mechanism and the cooling system, so that the stress relief mechanism and the cooling system can work simultaneously;

[0037] Furthermore, when the turntable 16 rotates, it will drive the connecting rod 17 to rotate, thereby driving the connecting frame 11 to move up and down. When the rolled metal sheet enters the pressure cover 10 and is located under the pressure roller 12, the metal sheet will be knocked by the pressure roller 12. At the same time, the resonance beads 28 and springs 29 in the pressure roller 12 will also provide more frequency knocking inside the pressure roller 12. The principle of knocking to remove internal stress is that when the knocking force acts on the metal surface, stress waves will be generated inside the material. These stress waves propagate and collide with each other inside the material, resulting in stress redistribution in local areas. In addition, knocking will also cause tiny plastic deformations of the metal. These deformations help to consume the residual stress inside the material. Through repeated knocking, the stress field inside the metal can be gradually balanced, and ultimately the purpose of reducing or homogenizing the internal stress can be achieved.

[0038] Furthermore, the operating speed of the stress relief mechanism is related to the feed speed of the metal blank. When the feed speed of the metal blank becomes faster, the operating speed of the stress relief mechanism will also become faster. At the same time, the number of times that multiple pressure rollers 12 strike the metal sheet will also increase in the same time. That is, the frequency of the pressure rollers 12 striking the metal sheet increases with the increase in the feed speed of the metal blank, thereby making the struck portion of the metal sheet more evenly distributed.

[0039] Embodiment three:

[0040] refer to Figure 1 and Figure 5 The cooling system includes a heat conducting plate 13, a piston 14, a serpentine tube 21, a water outlet pipe 22, a No. 1 check valve 23, a No. 2 check valve 24, a water tank 25, a water inlet pipe 26, and a hose 27. The serpentine tube 21 is fixedly arranged in the heat conducting plate 13. When the rolled metal sheet passes over the heat conducting plate 13, the heat is transferred from the heat conducting plate 13 to the serpentine tube 21. At the same time, the piston will also start to pump the water in the water tank 25 into the serpentine tube 21, and then flow into the water tank 25 through the water inlet pipe 26;

[0041] In this embodiment, the rolled metal sheet will pass through the pressure cover 10 after the internal stress is removed, and then pass through the heat conductive plate 13. The metal sheet will be heated before rolling to reduce the hardness of the metal blank and improve the plasticity to obtain better processing performance for rolling. After rolling, the metal sheet will still have residual temperature. When the metal sheet with residual temperature passes through the heat conductive plate 13, part of the heat of the metal sheet will be taken away by the heat conductive plate and the heat dissipation system, thereby accelerating the cooling speed of the metal sheet, reducing the cooling time, and making the production more efficient.

[0042] Embodiment 4:

[0043] Different from the third embodiment, Figure 5 , this embodiment also has the following further contents:

[0044] The water inlet end of the No. 1 check valve 23 is connected to the piston 14 through a hose 27, the water outlet end of the No. 1 check valve 23 is connected to the serpentine pipe 21 through a hose 27, the water inlet end of the No. 2 check valve 24 is connected to the water tank 25 through a water inlet pipe 26, and the water outlet end of the No. 2 check valve 24 is connected to the piston 14 through a water inlet pipe 26;

[0045] The first check valve 23 and the second check valve 24 determine the flow direction of water in the water tank 25. Figure 5 As shown, when the piston 14 moves upward, water is pumped out, and the water flows from the water tank 25 through the water inlet pipe 26 into the cavity in the piston, during which it passes through the No. 2 one-way valve 24. Due to the unidirectional conductivity of the one-way valve, the water cannot flow back to the water tank 25 through the No. 2 one-way valve 24 after passing through the No. 2 one-way valve 24. When the piston 14 is pressed down, the internal space of the piston 14 is squeezed, and the water in the piston 14 will flow into the serpentine tube 21 through the hose 27, during which it passes through the No. 1 one-way valve 23. Also due to the unidirectional conductivity of the one-way valve, the water cannot flow back to the piston 14 after passing through the No. 1 one-way valve 23. As the piston 14 is squeezed, the water will be squeezed into the serpentine tube 21. Due to the thermal conductivity of metal and water, part of the heat on the rolled metal sheet will be taken away, thereby making the metal sheet cool faster.

[0046] Embodiment five:

[0047] refer to Figure 1 and Figure 5 The cooling system includes a heat conducting plate 13, a piston 14, a serpentine tube 21, a water outlet pipe 22, a No. 1 check valve 23, a No. 2 check valve 24, a water tank 25, a water inlet pipe 26, and a hose 27. The serpentine tube 21 is fixedly arranged in the heat conducting plate 13. When the rolled metal sheet passes over the heat conducting plate 13, the heat is transferred from the heat conducting plate 13 to the serpentine tube 21. At the same time, the piston will also start to pump the water in the water tank 25 into the serpentine tube 21, and then flow into the water tank 25 through the water inlet pipe 26;

[0048] In this embodiment, the rolled metal sheet will pass through the pressure cover 10 after the internal stress is removed, and then pass through the heat conductive plate 13. The metal sheet will be heated before rolling to reduce the hardness of the metal blank and improve the plasticity to obtain better processing performance for rolling. After rolling, the metal sheet will still have residual temperature. When the metal sheet with residual temperature passes through the heat conductive plate 13, part of the heat of the metal sheet will be taken away by the heat conductive plate and the heat dissipation system, thereby accelerating the cooling speed of the metal sheet, reducing the cooling time, and making the production more efficient.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
