[0044] Example 1:

[0045] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 , the present invention provides an embodiment: an anti-rebound plate rolling machine, including a pre-processing device 1, the interior of the pre-processing device 1 is penetrated by two sets of conveyor belts 21, the outer wall of one side of the pre-processing device 1 is installed with a motor box 2 13, the interior of the motor box 2 13 is installed with a control motor 2 14, the output end of the control motor 2 14 is installed with a main rod 16, the main rod 16 is located inside the pre-processing device 1, the outer surface of the main rod 16 is installed with a pre-bending roller 15, the outer surface of the main rod 16 Two groups of small electric push rods 17 are installed on the surface, and the two groups of small electric push rods 17 are respectively located on both sides of the pre-bending roller 15. The output end of the small electric push rod 17 is installed with an electric gripper 18. The back wall of the pretreatment device 1 is installed with an electric push rod 2 19. The output end of the electric push rod 2 19 is installed with a cleaning brush 20. The cleaning brush 20 is located behind the pre-bending roller 15. The back wall of the pretreatment device 1 is installed with a limit baffle 32, and the limit baffle 32 is located below the electric push rod 2 19.

[0046] Furthermore, the metal sheet to be rolled is placed on the conveyor belt 21, and the upper surface of the sheet is cleaned with a cleaning brush 28. Then, it is sent to the pretreatment device 1 for heat treatment to change the internal structure and stress state of the metal sheet, thereby reducing its rebound in the subsequent rolling process. Then, under the guidance of the traction roller 12, the sheet is sent to the bottom of the pre-bending roller 15. A pressure sensor is installed on the gripper of the electric gripper 18. When the head of the sheet passes through the electric gripper 18, the pressure sensor on it will When the pressure is detected, the electric clamp 18 immediately clamps the plate, and at the same time the small electric push rod 17 contracts, so that the plate is close to the surface of the pre-bending roller 15. Then the control motor 14 is started to drive the main rod 16 and the pre-bending roller 15 to rotate, so that the plate is bent along the surface of the pre-bending roller 15, and only the head of the plate is pre-bent. When the plate is bent along the pre-bending roller 15, the electric push rod 19 extends, so that the cleaning brush 20 is close to the plate on the surface of the pre-bending roller 15. The cleaning brush 20 is composed of a magnet and soft bristles. The brush composition has the same structure as the cleaning brush 28 and is used to absorb metal debris on the surface of the plate and clean dust. After the pre-bending process, the motor 2 14 is controlled to rotate in the opposite direction. The plate moves in the opposite direction along the traction roller 12 and the lower heating roller 2 under the action of the thrust. When the electric gripper 18 returns to its original position, the electric gripper 18 is released. At this time, the bending angle of the head of the plate is the same as the bending angle of the limit baffle 32. At this time, the lower heating roller 2 is rotated to push the plate between the limit baffle 32 and the cleaning brush 20 to be sent out from the outlet. Under the limiting effect of the limit plate, the plate is smoothly delivered to the plate rolling machine body 31 for subsequent plate rolling processing. Before formal rolling, the plate end is pre-bent by controlling the coordination of motor 2 14, pre-bending roller 15, main rod 16, small electric push rod 17 and electric gripper 18 to reduce the amount of rebound in the subsequent rolling process, which helps to improve the production efficiency and quality of subsequent plate rolling. The coordination of small electric push rod 17 and electric gripper 18 can adapt to plates of different thicknesses and pre-bend the plates.

[0047] Example 2:

[0049] Furthermore, the lower heating roller 2 and the upper heating roller 3 are preheated, and the temperature sensor 11 is used to detect the real-time temperature of the lower heating roller 2 and the upper heating roller 3. When the temperature of the lower heating roller 2 and the upper heating roller 3 reaches the preset value, the heating is stopped. At this time, the plate is transported by the conveyor belt 21 to the space between the lower heating roller 2 and the upper heating roller 3. At the same time, the motor 9 is controlled to run, driving the lower heating roller 2 to rotate, further pushing the plate. At the same time, the high-definition camera 10 will detect the position of the plate, and the main controller 29 will control the electric push rod 4 to extend and retract according to the thickness of the plate to change the position of the upper heating roller 3 so that the upper heating roller 3 is close to the upper surface of the plate. The surface improves the efficiency of heat treatment of the plate, changes the stress state of its internal structure through heat treatment, helps to pre-bend the end of the plate in the subsequent rolling process, further reduces the rebound amount of the plate in the subsequent plate rolling process, and effectively reduces the occurrence of plate rebound. The high-definition camera 10 is not only used to detect the position of the plate, but also to monitor the preheating and pre-bending process. When a fault occurs in the pretreatment process, the main controller 29 will generate an alarm signal and display the video image in the pretreatment device 1 on the display screen of the main controller 29, so that the staff can find the fault point in time and repair it in time.

[0050] Example 3,

[0051] See also Figure 1 、 Figure 8 and Figure 11, an embodiment of the present invention provides: an anti-rebound plate rolling machine, the bottom of the pre-processing device 1 is installed with a base plate 30, the top of the base plate 30 is installed with a master controller 29 and a plate rolling machine body 31, the master controller 29 is located on one side of the pre-processing device 1, the plate rolling machine body 31 is located behind the pre-processing device 1, the plate rolling machine body 31 includes a bottom plate, the top of the bottom plate is provided with two groups of slide grooves 42, the interior of the bottom plate is installed with two groups of servo motors 35, the output end of the servo motor 35 is installed There is a screw rod 36, which is located inside a slide groove 42. A guide rod 37 is installed inside the slide groove 42, and the guide rod 37 is located below the screw rod 36. The outer surfaces of the guide rod 37 and the screw rod 36 are sleeved with a slider 38. The top of the slider 38 is installed with an electric telescopic rod 39, which is located above the bottom plate. The output end of the electric telescopic rod 39 is installed with an electric telescopic rod 3 40, and the output end of the electric telescopic rod 3 40 is installed with an arc-shaped cleaning claw 41.

[0052] Furthermore, before the plate rolling machine main body 31 rolls the plate, the high-definition camera 2 34 is first used to capture the images of the upper working roller 7 and the lower working roller 6, and the image recognition technology is used to determine whether the working area is clean and tidy. If impurities are detected on the surfaces of the upper working roller 7 and the lower working roller 6, the electric telescopic rod 2 39 is extended and retracted so that the height of the arc-shaped cleaning claw 41 is the same as that of the lower working roller 6. At the same time, the electric telescopic rod 3 40 is extended to drive the arc-shaped cleaning claw 41 to approach the lower working roller 6. At this time, the lower working roller 6 is in a rotating state, and the servo motor 2 35 is started to make the arc-shaped cleaning claw 41 move parallel to the surface of the lower working roller 6. The impurities on the surface of the lower working roller 6 are cleaned by the cooperation of the lower working roller 6, the arc-shaped cleaning claw 41 and the servo motor 2 35, and then the two groups of electric telescopic rods 2 39 are controlled to extend so that the height of the arc-shaped cleaning claw 41 is the same as that of the upper working roller 7. Then the electric telescopic rod 3 40 is controlled to extend to drive the two groups of arc-shaped cleaning claws 41 to move upward The upper working roller 7 is close to the upper working roller 7, and the arc-shaped cleaning claws 41 also move parallel to the upper working roller 7 with the operation of the servo motor 235. At this time, the upper working roller 7 is also in a rotating state.

By automatically detecting whether the working area is clean and automatically cleaning the working area, the degree of automation is improved to a certain extent, human intervention is reduced, and the accuracy of monitoring is improved. Since the human eye is affected by the range of vision and the degree of concentration, it is difficult to detect subtle impurities in the working area and the dimensional deviation of the metal sheet. Automated detection can perform continuous inspections, which greatly improves production efficiency, reduces manual participation, and thereby reduces the risk of direct contact between personnel and the machine, and improves the safety of the working environment. The main controller 29 is used to control the entire device, and the pretreatment device 1 cooperates with the plate rolling machine body 31 to achieve high-quality rolling processing of the metal sheet.

[0053] Example 4:

[0054] See also Figure 1 、 Figure 8 、 Figure 9 and Figure 10 , an embodiment of the present invention provides: an anti-rebound plate rolling machine, the top of the bottom plate is installed with a frame and a tail vertical plate, the tail vertical plate is located on one side of the frame, an arc clamp 47 is installed inside the frame, and an upper working roller 7 is installed at the output end of the arc clamp 47, and an open groove 44 is opened inside the frame and the tail vertical plate, and two groups of small electric push rods 2 45 are installed on the inner top walls of the frame and the tail vertical plate, and the small electric push rods 2 45 are located on the outside of the open groove 44, and a small electric push rod 3 46 is installed at the output end of the small electric push rod 2 45, and an arc clamp 47 is installed at the output end of the small electric push rod 3 46, and the arc clamp 47 is used to clamp the servo motor 3 43 and the upper working roller 7;

[0055] Two groups of lower working rollers 6 are installed between the frame and the tail vertical plate. The lower working rollers 6 are located between the two groups of arc-shaped cleaning claws 41. The lower working rollers 6 are located below and to the side of the upper working roller 7. Two groups of electric telescopic rods 33 are installed on the top of the frame. A high-definition camera 2 34 is installed on the outer surface of one side of the output end of the electric telescopic rod 33.

[0056] Furthermore, the pretreated plate is conveyed by the conveyor belt 21 and restricted by the limit plate to be sent between the upper working roller 7 and the lower working roller 6 in the plate rolling machine body 31, so that the upper working roller 7 and the lower working roller 6 rotate. At the same time, according to the specific thickness of the plate, the small electric push rod 2 45 is controlled to extend and retract, driving the upper working roller 7 to move in the vertical direction to change the gap between the upper working roller 7 and the lower working roller 6, ensuring that the plate is subjected to appropriate pressure during the rolling process and further reducing rebound. When the rolling is completed, the small electric push rod 3 46 in the tail vertical plate contracts, so that the arc clamp 47 releases the clamping of the upper working roller 7, and then the tail vertical plate is folded, so that the rolled plate can be taken out of the plate rolling machine body 31. Since the plate rolling machine body 31 is a symmetrical three-roller plate rolling machine, this structure can better control rebound and improve product precision. An anti-rebound mechanism is set in the plate rolling machine to further control rebound. If necessary, the position of the arc cleaning claw 41 can also be adjusted to apply additional pressure to the plate during the rolling process to prevent the plate from rebounding.

[0062] Furthermore, the method for using the plate rolling machine includes the following steps:

[0063] Step S1: First, place the metal sheet on the conveyor belt 21. Driven by the conveyor belt 21, the metal sheet passes under the second cleaning brush 28. The second cleaning brush 28 is used to clean the metal sheet to remove metal debris and dust on the surface of the sheet.

[0064] Step S2: Then, the lower heating roller 2 and the upper heating roller 3 are used to heat treat the passing plate;

[0065] Step S3: Then, the electric gripper 18 is used to clamp the head of the plate and pre-bend the plate;

[0066] Step S4: Before the plate rolling process, the working area is first checked for debris. If there is debris, the arc-shaped cleaning claws 41 are used to clean the impurities in the working area. Finally, the pre-bent plate is sent into the plate rolling machine body 31 for rolling process.

[0067] In step S3, the following steps are also included:

[0068] Step S31 , start the control motor 2 14 to drive the pre-bending roller 15 and the main rod 16 to rotate, so that the plate is bent around the surface of the pre-bending roller 15 .

[0069] Working principle: First, the upper surface of the plate is cleaned with a cleaning brush 28, and then it is sent to the pretreatment device 1 for heat treatment to change the internal structure and stress state of the metal plate, thereby reducing its rebound in the subsequent rolling process. Then, under the guidance of the traction roller 12, the plate will be sent to the bottom of the pre-bending roller 15. A pressure sensor is installed on the gripper of the electric gripper 18. When the head of the plate passes through the electric gripper 18, the pressure sensor thereon will detect the pressure, and the electric gripper 18 will immediately clamp the plate. At the same time, the small electric push rod 17 will contract, so that the plate is close to the surface of the pre-bending roller 15. Then the control motor 2 14 is started to drive the main rod 16 and the pre-bending roller 15 to rotate, so that the plate is bent along the surface of the pre-bending roller 15.

[0070] The plate is then pushed between the limit baffle 32 and the cleaning brush 20 to be sent out from the outlet. Before rolling, the working area is first checked to see if it is clean, and the working area is automatically cleaned. After ensuring that the working area is clean, the plate is smoothly sent to the rolling machine body 31 under the restriction of the limit plate for subsequent rolling processing.
