Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy plate rolling processing, and in particular to a metal plate and strip thickness automatic control device. Background Art

[0002] Sheet metal rolling refers to a pressure processing method in which a metal blank is passed through the gap between a pair of rotating rollers. Due to the compression of the rollers, the cross-section of the metal blank is reduced and the length is increased. Metal rolling is the most commonly used production method for producing aluminum alloy strips.

[0003] During the metal plate rolling process, the existing rolling equipment is prone to varying degrees of wear on the rollers, which is difficult to detect in time and make targeted adjustments. When the rollers are severely worn, the thickness of the rolled metal plates will vary significantly, which in turn affects the processing quality of the strip. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for automatically controlling the thickness of metal plates and strips to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a metal plate and strip thickness automatic control device, comprising a machine body and roller conveyors respectively installed on both sides of the machine body, and further comprising: The rolling mechanism is installed inside the machine body and is provided with two groups, one of which is the main rolling mechanism and the other is the auxiliary rolling mechanism. The rolling mechanism includes two fixed frames, rollers installed inside the fixed frames, and a lifting assembly for driving the fixed frames to rise and fall; A monitoring mechanism comprising a laser scanner mounted inside a fixed frame and a displacement assembly for driving the laser scanner to move; An adjusting mechanism, connected to the lifting assembly, for adjusting the position of the roller; The cleaning mechanism comprises an aggregate shell installed on the outer wall of one side of the fixing frame, a scraper installed on the inner wall of the aggregate shell, and a recessed processing component installed inside the aggregate shell.

[0006] Furthermore, the lifting assembly includes a plurality of hydraulic cylinders mounted on the outer wall of the machine body and a lifting seat fixed to the extended ends of the plurality of hydraulic cylinders; The fixing frame is slidably connected to the bottom of the lifting seat along the length direction thereof.

[0007] Furthermore, the displacement assembly includes a first screw rod rotatably connected to the interior of the fixing frame, a first motor mounted on the outer wall of the fixing frame, and a slider threadedly connected to the exterior of the first screw rod; The output end of the first motor is fixedly connected to one end of the first screw rod; A guide rod is fixedly connected to the interior of the fixing frame, the sliding block is slidably sleeved on the exterior of the guide rod, and the laser scanner is installed inside the sliding block.

[0008] Furthermore, the adjustment mechanism includes a second screw rod rotatably connected to the outer wall of one side of the lifting seat, a linkage block threadedly connected to the outside of the second screw rod, and a second motor installed at one end of the lifting seat; The output end of the second motor is fixedly connected to one end of the second screw rod; The linkage block is fixedly connected to the fixing frame.

[0009] Furthermore, the depression processing assembly includes a movable block slidably connected to the inner wall of the aggregate shell, a cover body fixed to one end of the movable block, and a driving assembly for driving the movable block to move; A driven block is slidably connected to the interior of the cover body, a plurality of balls are rotatably connected to the outer wall of one side of the driven block, a plurality of springs are fixed to the outer wall of the other side of the driven block, and the other end of the spring is fixed to the inner wall of the cover body.

[0010] Furthermore, the driving assembly includes a third screw rod rotatably connected to the inside of the aggregate shell and a third motor installed on the outer wall of the aggregate shell, the output end of the third motor is fixedly connected to one end of the third screw rod, and the movable block is threadedly connected to the outside of the third screw rod.

The suction pipe is a metal braided hose.

[0012] Furthermore, a vent is provided on the outer wall of the aggregate shell, and a filter is installed inside the vent.

[0013] Compared with the prior art, the metal plate and strip thickness automatic control device provided by the present invention has the following beneficial effects: 1. By scanning the outside of the roller, the location where the roller is most worn, that is, the concave location, is promptly discovered and located. After the roller is away from the aluminum alloy plate, the position of the roller where the concave location is currently detected is adjusted to move the concave location out of the rolling range of the aluminum alloy plate, thus avoiding the problem of large differences in the rolled thickness of the aluminum alloy plate due to the large degree of roller wear; 2. When the roller rotates, the scraper strips are used to scrape off the oxides on the outer wall of the roller. At the same time, the driving ball is always moved along the surface of the roller. When the ball moves to the inside of the recessed position, the oxides hidden in the recessed position can be crushed and dispersed. The pumping tube is used to extract the crushed oxides, thus avoiding the problem that the oxides hidden in the recessed position affect the accuracy of the laser scanner in detecting the recessed position on the outside of the roller.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: See Figure 1 - Figure 8 , a metal plate and strip thickness automatic control device, comprising a body 1 and roller conveyors 2 respectively installed on both sides of the body 1, and further comprising: The rolling mechanism is installed inside the machine body 1 and is provided with two groups, one of which is the main rolling mechanism, that is, the rolling mechanism on the right side, and the other is the auxiliary rolling mechanism, that is, the rolling mechanism on the left side. The rolling mechanism includes two fixed frames 3, rollers 4 installed inside the fixed frames 3, and a lifting assembly for driving the fixed frames 3 to rise and fall. One end of the roller 4 is connected to a servo motor for driving the roller 4 to rotate. The servo motor is installed on the outer wall of the fixed frame 3. The lifting assembly includes multiple hydraulic cylinders 8 installed on the outer wall of the machine body 1 and a lifting seat 9 fixed to the extended ends of the multiple hydraulic cylinders 8; the fixed frame 3 is slidably connected to the bottom of the lifting seat 9 along the length direction; By controlling the hydraulic cylinder 8 to drive the lifting seat 9 to rise and fall, the fixed frame 3 moves accordingly, and the height of the rollers 4 can be adjusted. By adjusting the height of the upper roller 4 and changing the distance between the two rollers 4 in the same group, the thickness of the aluminum alloy plate can be controlled. The aluminum alloy plate to be rolled is conveyed by the roller conveyor 2 on the right. After the aluminum alloy plate enters the interior of the machine body 1, the two rollers 4 rotating clockwise at the top and counterclockwise at the bottom roll the aluminum alloy plate. After rolling to the set thickness, the rolled strip is conveyed away by the roller conveyor 2 on the left. Among them, when the two rollers 4 on the right are rolling the aluminum alloy plate, the two rollers 4 on the left are in a state of being away from the aluminum alloy plate and not in contact with the aluminum alloy plate. When it is necessary to adjust the position of a roller 4 on the right, the two rollers 4 on the left are first driven closer to each other to reach the rolling position, and then the two rollers 4 on the right are driven away from each other. The aluminum alloy plate is rolled by the two rollers 4 on the left. At the same time, the rollers 4 that need to be adjusted are adjusted. After the adjustment is completed, the two rollers 4 on the right are driven closer to each other to reach the rolling position. After the rolling of the aluminum alloy plate between the left and right rollers 4 is completed, the two rollers 4 on the left are driven away from each other.

[0019] The monitoring mechanism includes a laser scanner 5 mounted inside a fixed frame 3 and a displacement assembly for driving the laser scanner 5 to move. The displacement assembly includes a first screw rod 10 rotatably connected to the inside of the fixed frame 3, a first motor 26 mounted on the outer wall of the fixed frame 3, and a slider 11 threadedly connected to the outside of the first screw rod 10. The output end of the first motor 26 is fixedly connected to one end of the first screw rod 10. A guide rod 12 is also fixedly connected to the inside of the fixed frame 3. The slider 11 is slidably connected to the outside of the guide rod 12. The laser scanner 5 is mounted inside the slider 11. When the roller 4 is in use, the first motor 26 is controlled to drive the first screw rod 10 to rotate clockwise, and the slider 11 is driven to move from the front end of the first screw rod 10 to its rear end, and the laser scanner 5 moves synchronously to scan the outside of the roller 4. When the first motor 26 is controlled to drive the first screw rod 10 to rotate counterclockwise, the slider 11 is driven to move from the rear end of the first screw rod 10 to its front end, and the laser scanner 5 moves synchronously to also scan the outside of the roller 4, and timely finds the position of the roller 4 with a large degree of wear, that is, the concave position, and locates it, and sends a signal to the controller. The controller first controls the position of the rollers 4 on the left and right sides, and then controls the second motor 15 to operate, adjusts the current position of the roller 4, and moves the concave position out of the rolling range of the aluminum alloy plate, thereby avoiding the problem of large differences in the rolled thickness of the aluminum alloy plate due to the large degree of wear of the roller 4. The first screw rod 10 can be replaced by a reciprocating screw rod. Therefore, the laser scanner 5 can be driven to move back and forth by simply controlling the first motor 26 to drive the first screw rod 10 to rotate clockwise.

[0020] An adjustment mechanism, connected to the lifting assembly and used to adjust the position of the roller 4, includes a second screw rod 13 rotatably connected to the outer wall of one side of the lifting base 9, a linkage block 14 threadedly connected to the outside of the second screw rod 13, and a second motor 15 mounted on one end of the lifting base 9; the output end of the second motor 15 is fixedly connected to one end of the second screw rod 13; the linkage block 14 is fixedly connected to the fixed frame 3; When the second motor 15 is controlled to drive the second screw rod 13 to rotate clockwise, the linkage block 14 is used to drive the fixed frame 3 to move forward, thereby driving the roller 4 to move forward, so that the recessed position of the roller 4 is moved out of the rolling range of the aluminum alloy plate. When the second motor 15 is controlled to drive the second screw rod 13 to rotate counterclockwise, the linkage block 14 is used to drive the fixed frame 3 to move backward, thereby driving the roller 4 to move backward, so that the recessed position of the roller 4 is moved out of the rolling range of the aluminum alloy plate.

[0021] The cleaning mechanism includes a detachable aggregate shell 6 mounted on the outer wall of one side of the fixed frame 3, a scraper 7 mounted on the inner wall of the aggregate shell 6, and a recessed processing component mounted inside the aggregate shell 6. The recessed processing component includes a movable block 16 slidably connected to the inner wall of the aggregate shell 6, a cover body 17 fixed to one end of the movable block 16, and a driving component for driving the movable block 16 to move; a driven block 18 is slidably connected to the interior of the cover body 17, a plurality of balls 19 are rotatably connected to the outer wall of one side of the driven block 18, a plurality of springs 20 are fixed to the outer wall of the other side of the driven block 18, the other end of the spring 20 is fixed to the inner wall of the cover body 17, and the driving component includes a driven block 18 rotatably connected to the aggregate shell 6 The internal third screw rod 21 and the third motor 22 installed on the outer wall of the aggregate shell 6, the output end of the third motor 22 is fixedly connected to one end of the third screw rod 21, the movable block 16 is threadedly connected to the outside of the third screw rod 21, and the third screw rod 21 can also be replaced by a reciprocating screw rod to drive the movable block 16 to move back and forth. A suction pipe 23 is installed inside the driven block 18, one end of the suction pipe 23 passes through the driven block 18, and the other end of the suction pipe 23 extends to the outside of the aggregate shell 6 and is connected to the negative pressure dust collection equipment. The suction pipe 23 is a metal braided hose, and a vent 24 is provided on the outer wall of the aggregate shell 6, and a filter 25 is installed inside the vent 24; When the roller 4 rotates, the scraper 7 scrapes off the oxide on the outer wall of the roller 4. At the same time, when the third motor 22 is controlled to drive the third screw rod 21 to rotate clockwise, the movable block 16 is driven to move forward. When the third motor 22 is controlled to drive the third screw rod 21 to rotate counterclockwise, the movable block 16 is driven to move backward. When the movable block 16 moves, the cover body 17 is driven to move synchronously along the outside of the roller 4. The elastic action of the spring 20 makes the ball 19 always move along the surface of the roller 4. When the ball 19 moves to the inside of the recessed position, the oxide hidden in the recessed position can be crushed and dispersed, and the crushed oxide can be extracted with the help of the extraction pipe 23, thereby avoiding the problem that the oxide hidden in the recessed position affects the accuracy of the laser scanner 5 in detecting the recessed position of the roller 4.

[0022] Working principle: When in use, the aluminum alloy sheet to be rolled is conveyed by the roller conveyor 2 on the right. After the aluminum alloy sheet enters the interior of the machine body 1, the two rollers 4 rotating clockwise on the upper side and counterclockwise on the lower side roll the aluminum alloy sheet. After rolling to the set thickness, the rolled strip is conveyed away by the roller conveyor 2 on the left side. During use, the roller 4 drives the first screw rod 10 to rotate clockwise by controlling the first motor 26, and drives the slider 11 to move from the front end of the first screw rod 10 to its rear end. The laser scanner 5 moves synchronously to scan the outside of the roller 4. When the first motor 26 drives the first screw rod 10 to rotate counterclockwise, the slider 11 moves from the rear end of the first screw rod 10 to its front end. The laser scanner 5 moves synchronously. The controller controls the hydraulic cylinder 8 on the left to first drive the two rollers 4 on the left to approach each other to reach the rolling position, and then drives the two rollers 4 on the right to move away from each other. The aluminum alloy plate is rolled by the two rollers 4 on the left. At the same time, the control adjustment mechanism roller 4 is adjusted to move the depressed position of the roller 4 out of the rolling range of the aluminum alloy plate. After the adjustment is completed, the two rollers 4 on the right are driven to approach each other to reach the rolling position. After the aluminum alloy plate is rolled between the left and right rollers 4, the two rollers 4 on the left are driven away from each other, and the aluminum alloy plate is continued to be rolled by the two rollers 4 on the right. When the roller 4 rotates, the scraper 7 scrapes off the oxide on the outer wall of the roller 4. At the same time, when the third motor 22 is controlled to drive the third screw rod 21 to rotate clockwise, the movable block 16 is driven to move forward. When the third motor 22 is controlled to drive the third screw rod 21 to rotate counterclockwise, the movable block 16 is driven to move backward. When the movable block 16 moves, the cover body 17 is driven to move synchronously along the outside of the roller 4. The elastic action of the spring 20 makes the ball 19 always move along the surface of the roller 4. When the ball 19 moves to the inside of the recessed position, the oxide hidden in the recessed position can be crushed and dispersed, and the crushed oxide can be extracted with the help of the extraction pipe 23, thereby avoiding the problem that the oxide hidden in the recessed position affects the accuracy of the laser scanner 5 in detecting the recessed position of the roller 4.
