Description

Technical Field

[0001] The invention relates to the technical field of plate rolling machine alignment, and in particular to a plate alignment device for a plate rolling machine and a use method thereof. Background Art

[0002] Plate rolling machine is an important industrial equipment, which is mainly used to roll metal plates into required round, arc or conical workpieces through continuous bending deformation. This equipment is widely used in shipbuilding, boiler manufacturing, aviation, hydropower, chemical industry, metal structure and machinery manufacturing industries. The working principle of the plate rolling machine is to use the principle of three points forming a circle. By adjusting the relative position and pressure between the side rollers and the upper roller of the plate rolling machine, the metal plate is plastically deformed under the action of the rollers, and then rolled into the required shape.

[0003] The development of plate rolling machines has undergone an evolution from mechanical hydraulics to CNC. Early plate rolling machines were mostly mechanical, complicated to operate and inefficient. With the advancement of hydraulic technology and automated control technology, modern plate rolling machines have achieved hydraulic drive and CNC operation, improving rolling accuracy and production efficiency. CNC plate rolling machines achieve precise control of the rolling process through CNC systems, can automatically generate programs, and perform corrections and storage, achieving a higher degree of automation and intelligence.

[0025] A plurality of rollers 5 are provided between the first support plate 6 and the second support plate 18 , and the plurality of rollers 5 are bearing-connected to the first support plate 6 and the second support plate 18 . A first motor 7 is fixedly connected to the left side of the first support plate 6 , and the first motor 7 is fixedly connected to one end of the roller 5 .

[0026] The lower plane of the first clamping block 9 is flush with the upper top surface of the roller 5 , and the upper plane of the first clamping block 9 is flush with the lower bottom surface of the grinding wheel 12 .

[0027] Specifically, the rotation of the output end of the first motor 7 is used to drive the roller 5 to roll, thereby driving the upper plate to move.

[0029] Specifically, the extension and retraction of the output end of the fourth push rod 20 is used to drive the first clamping block 9 to move left and right, thereby limiting the passing plate. The second infrared sensor 21 is used to detect whether there is a plate passing by. When the other second infrared sensor 21 detects infrared rays, it means that no plate is passing by. When the other second infrared sensor 21 cannot detect infrared rays, it means that a plate is passing by.

[0030] The detection ends and the emission ends of the two second infrared rays are both higher than the upper top surface of the roller 5 .

[0031] A second top plate 23 is provided on the upper side of the second clamping block 19, and the second top plate 23 is fixedly connected to the first support plate 6 and the second support plate 18, and a cleaning assembly is provided on the lower side of the second top plate 23;

[0032] The cleaning assembly includes a fifth push rod 24, a second push block 22, a pressure sensor 25, a plurality of springs 26, a slider 27 and a plurality of brushes 28. The fifth push rod 24 is fixedly connected to the upper side of the second top plate 23, the output end of the fifth push rod 24 passes through the second top plate 23, the second push block 22 is fixedly connected to the output end of the fifth push rod 24, an active cavity is provided inside the second push block 22, the pressure sensor 25 is fixedly connected inside the active cavity, a plurality of springs 26 are fixedly connected to the lower side of the pressure sensor 25, the slider 27 is fixedly connected to the lower ends of the plurality of springs 26, the slider 27 is slidably connected to the active cavity, and a plurality of brushes 28 are fixedly connected to the lower side of the slider 27.

[0033] Specifically, the extension and retraction of the output end of the fifth push rod 24 is used to drive the brush 28 to move up and down. When the brush 28 presses the plate, the slider 27 moves upward to compress the spring 26. The pressure sensor 25 detects the pressure value of the compressed spring 26 and converts it into an electrical signal and sends it to the control box 2. The brush 28 cleans the rust particles on the upper surface of the plate.

[0034] The upper wall of the base 4 is provided with a plurality of material passing grooves, and the interior of the base 4 is slidably connected with the collecting box 3 .

[0035] Specifically, the material chute is used to pass the fallen rust particles, and the interior of the collecting box 3 is used to collect the fallen rust particles.

[0036] A control module and a detection module are provided inside the control box 2. The control module is signal-connected to the detection module. The control module is signal-connected to the first motor 7, the second motor 17, the first push rod 8, the second push rod 11, the third push rod 13, the fourth push rod 20, and the fifth push rod 24. The detection module is signal-connected to the first infrared sensor 10, the second infrared sensor 21, and the pressure sensor 25.

[0037] The following steps are involved:

[0038] S1: The staff inputs the width and thickness of the plate, and the control box 2 automatically adjusts the moving distance of the first block 9 and the second push rod 11;

[0039] Specifically, assuming that when the output ends of the first push rod 8 and the second push rod 11 are fully retracted, the distance between the two first blocks 9 and the two second blocks 19 is q, and the control box 2 calculates the distance that the first push rod 8 and the second push rod 11 need to move by subtracting the width of the plate from q and dividing the result by 2. The initial state of the second push rod 11 is fully extended, and the distance that the output end of the second push rod 11 needs to retract is the thickness of the plate.

[0040] S2: placing the plate on the roller 5, the roller 5 rolls to transport the plate, and the first clamping block 9 aligns it during the transport;

[0041] S3: When the plate moves to the bottom of the first top plate 15, the first infrared sensor 10 is used to determine whether there is rust on the upper surface of the plate, the control box 2 calculates the thickness of the rust, and the rust removal component automatically removes the rust;

[0042] Specifically, assuming that the height of the first clamping block 9 is w, when the detection end of one of the first infrared sensors 10 cannot detect infrared rays, it indicates that there is rust on the plate, and the roller 5 stops rotating. The control box 2 controls the output end of the second push rod 11 to move upward until the detection end of one of the first infrared sensors 10 detects infrared rays. The control box 2 records the retracted length value of the second push rod 11, and the retracted length value of the second push rod 11 is the thickness value of the rust. The control box 2 calculates the distance value that the output end of the third push rod 13 needs to extend by subtracting the thickness value of the iron plate from w, and then subtracting the thickness value of the rust. The output end of the third push rod 13 extends to control the grinding wheel 12 to move downward rapidly. When the output end of the third push rod 13 extends When the length value reaches the distance value calculated before, the control box 2 controls the second motor 17 to start, the grinding wheel 12 rotates to remove rust, and the output end of the third push rod 13 slowly moves downward. The distance extended by the output end of the third push rod 13 is the thickness value of the rust. When the rust is cleaned, the output end of the third push rod 13 retracts to control the grinding wheel 12 to return, and the second motor 17 is turned off. When the detection end of one of the first infrared sensors 10 detects infrared rays, it means that there is no rust on the plate, and the roller 5 continues to rotate to drive the plate to move. Through the detection of the first infrared sensor 10, it is determined whether there is rust on the upper surface of the plate. The control box 2 calculates the thickness of the rust, and the rust removal component automatically and accurately removes the rust.

[0043] S4: When the plate moves to the bottom of the second top plate 23, the control box 2 automatically adjusts the pressure of the brush 28 according to the thickness of the rust, and cleans the rust particles on the upper surface of the plate with different efficiencies;

[0044] Assume that the thickness of the rust is x. When the second motor 17 of the previous process is started, the control box 2 turns on the second infrared sensor 21. When the detection end of one of the second infrared sensors 21 cannot detect infrared rays, the roller 5 stops rotating. The control box 2 controls the output end of the fifth push rod 24 to move downward. When x≤1mm, it means that the amount of rust particles generated is small and easy to clean. The brush 28 does not need too much pressure. The pressure sensor 25 sets the pressure value to F. Until the pressure sensor 25 detects the previously set value, the output end of the fifth push rod 24 stops extending, the roller 5 starts rotating, and the brush 28 performs inefficient cleaning of rust particles. When x>1mm, it indicates that the amount of rust particles generated is too large and is not easy to clean. Some rust particles will stick to the surface of the plate. The brush 28 requires greater pressure for cleaning. The pressure value set by the pressure sensor 25 is 2F. Until the pressure sensor 25 detects the previously set value, the output end of the fifth push rod 24 stops extending, the roller 5 starts to rotate, and the brush 28 performs efficient cleaning of the rust particles. The rust thickness value recorded by the control box 2 automatically adjusts the pressure of the brush 28 to clean the rust particles on the upper surface of the plate with different efficiencies.

[0045] S5: When the plate moves to the plate rolling machine 1, the plate rolling machine 1 rolls it.
