Description

Technical Field

[0001] The utility model relates to the field of strip steel detection, in particular to a strip steel shape flatness detection device. Background Technique

[0002] Strip steel is a narrow and long steel plate produced by various rolling enterprises to meet the needs of different industrial departments for industrial production of various metal or mechanical products. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving.

[0003] During the production of strip steel, its flatness usually needs to be detected. The existing flatness detection method generally uses a stylus sensor to contact the surface of the strip steel, and the displacement change of the stylus is measured to reflect the unevenness of the strip steel surface, so as to detect its flatness.

[0004] When detecting the flatness of the existing strip steel, it is generally transported to the detection area through a transportation component for detection. It is found in use and observation that when the number of transported strip steels is too large, they will deviate from the central area of the transportation component under the extrusion effect, which will cause deviation in the detection area of the strip steel, and then reduce the accuracy of the detection result of the strip steel by the device.

[0005] Therefore, a strip steel shape flatness detection device is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0009] Preferably, a baffle is fixedly connected to the end of the pull rope; the fixing plate is located between the pressure plate and the baffle; when the staff resets the pull rope, if excessive force is applied, the pull rope will move quickly along the circular hole, and when the pull rope is about to detach from the circular hole, the baffle will come into contact with the circular ring, at which time the pull rope will stop moving under the pressure between the baffle and the circular ring, thereby reducing the situation where the pull rope detaches from the circular hole when adjusting the position, and improving the stability of the device in adjusting the pull rope.

[0010] Preferably, a plurality of ball bearings are rotatably connected to the middle part of the pressure plate; the ball bearings are arranged in a circular array; when the steel strip and the pressure plate come into contact, the ball bearings will also come into contact with the steel strip, and the ball bearings will convert the sliding friction between the steel strip and the pressure plate into rolling friction, thereby reducing the friction between the steel strip and the pressure plate and reducing the damage to the surface of the steel strip caused by friction.

[0011] Preferably, an air pipe is connected in the middle of the connecting plate; the connecting plate and the roller are in a connected relationship; a plurality of air holes are opened in the middle of the roller; during operation, the air pipe can be connected to an air pump so that the air flow enters the interior of the connecting plate through the air pipe, and then the air flow enters the interior of the roller and is ejected from the air holes. The air flow reaches the surface of the strip and cleans it, thereby reducing impurities attached to the surface of the strip, improving the cleanliness of the surface of the strip, and reducing the interference of impurities on the surface of the strip on the detection results.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The following gives specific embodiments.

[0027] Please refer to Figures 1 to 6 As shown, a strip steel shape flatness detection device according to an embodiment of the present invention includes a support base 1; a pair of vertical plates 12 are fixedly connected to the top of the support base 1; a transport component 13 is installed between the vertical plates 12; a detection component 14 is installed between the vertical plates 12; a connecting plate 19 is arranged in the middle of the vertical plates 12; a roller 15 is rotatably connected between a pair of vertical plates 12; fixing plates 16 are symmetrically fixedly connected to the middle of the roller 15; a plurality of springs 17 are fixedly connected to the middle of the fixing plates 16; the end of the spring 17 is fixedly connected to a pressing plate 18; the surface of the pressing plate 18 is an arc structure; during operation, after the strip steel is placed on the top of the transport component 13, the device is started, and the transport component 13 will transport the strip steel. When the strip steel moves, it will pass through the roller 15. When the strip steel is not in the middle area of the transport component 13, it will come into contact with the pressing plate 18. The pressing plate 18 will be compressed together with the spring 17 under the extrusion of the strip steel. At the same time, the pressing plate 18 will transmit the frictional force between it and the strip steel to the fixing plate 16, causing the roller 15 to rotate. Subsequently, the spring 17 will release elastic force to make the pressing plate 18 extrude the strip steel, and the strip steel will move under the extrusion of the pressing plate 18 until the extrusion of the pressing plate 18 stops. At this time, the strip steel will be in the central area of the transport component 13. Subsequently, the strip steel will move to the detection component 14, and the detection component 14 will detect its flatness. Finally, the detected strip steel will be transported by the transport component 13 into the receiving device; when the strip steel deviates, it will be extruded by the pressing plate 18, realizing the deviation correction and positioning before the flatness detection of the strip steel, improving the accuracy of the position of the strip steel during detection, and reducing the error caused by deviation during the strip steel detection.

[0028] Please refer to Figures 2 to 4As shown, a plurality of pull ropes 2 are fixedly connected to the middle of the pressure plate 18; a circular ring 25 is rotatably connected to the middle of the vertical plate 12; the circular ring 25 and the connecting plate 19 are rotatably connected; a plurality of circular holes 22 are opened in the middle of the circular ring 25 and the fixed plate 16; a plurality of second convex teeth 24 are fixedly connected to the inner side wall of the circular hole 22; a plurality of first convex teeth 23 are fixedly connected to the middle of the pull rope 2; the ends of the first convex teeth 23 and the second convex teeth 24 are correspondingly arranged; when it is necessary to detect strip steel of different sizes, the pull rope 2 can be pulled so that the pressure plate 18 moves toward the fixed plate 16 under the pulling force of the pull rope 2, at which time the distance between the pair of pressure plates 18 will change, and the pull rope 2 will move the pressure plate 18 to the fixed plate 16. When the rope 2 moves, it will move along the circular hole 22, and the first protruding tooth 23 will move with the pull rope 2 and slide along the surface of the second protruding tooth 24. When the pull rope 2 stops moving, the first protruding tooth 23 will contact the surface of the second protruding tooth 24. At this time, the pull rope 2 will be limited by the friction between the first protruding tooth 23 and the second protruding tooth 24. When the pull rope 2 needs to be reset, the pull rope 2 can be pulled hard to make the first protruding tooth 23 slide in the opposite direction over the second protruding tooth 24; pulling the pull rope 2 can change the distance between the pressure plates 18, so that the device can correct and position strip steels of different sizes, thereby improving the flexibility and adaptability of the device in positioning when detecting the flatness of strip steels of various sizes.

[0029] See also Figure 3 As shown, the end of the pull rope 2 is fixedly connected with a baffle 3; the fixing plate 16 is located between the pressure plate 18 and the baffle 3; when the staff resets the pull rope 2, if excessive force is applied, the pull rope 2 will move quickly along the circular hole 22, and when the pull rope 2 is about to escape from the circular hole 22, the baffle 3 will come into contact with the circular ring 25. At this time, the pull rope 2 will stop moving under the pressure between the baffle 3 and the circular ring 25, thereby reducing the situation where the pull rope 2 escapes from the circular hole 22 when adjusting the position, and improving the stability of the device in adjusting the pull rope 2.

[0030] See also Figure 2 As shown, a plurality of balls 4 are rotatably connected to the middle part of the pressure plate 18; the balls 4 are arranged in a circular array; when the steel strip comes into contact with the pressure plate 18, the balls 4 will also come into contact with the steel strip, and the balls 4 will convert the sliding friction between the steel strip and the pressure plate 18 into rolling friction, thereby reducing the friction between the steel strip and the pressure plate 18 and reducing the damage to the surface of the steel strip caused by friction.

[0031] See also Figures 2 to 6As shown, an air pipe 5 is connected to the middle of the connecting plate 19; the connecting plate 19 and the roller 15 are in a connected relationship; a plurality of air holes 52 are formed in the middle of the roller 15; during operation, the air pipe 5 can be externally connected to an air pump so that air flow will enter the inside of the connecting plate 19 through the air pipe 5, and then the air flow will enter the inside of the roller 15 and be ejected from the air holes 52. The air flow will reach the surface of the strip steel and clean it, reducing the impurities attached to the surface of the strip steel, improving the cleanliness of the strip steel surface, and reducing the interference of the strip steel surface impurities on the detection result.

[0032] Please refer to Figure 5 and Figure 6 As shown, a plurality of elastic sheets 6 are fixedly connected to the inner side wall of the roller 15; the end of the elastic sheet 6 is fixedly connected with a sliding rod 62; the sliding rod 62 and the air hole 52 are in clearance fit; during normal operation, the elastic sheet 6 will block the air hole 52. When the strip steel moves to the roller 15, it will come into contact with the sliding rod 62, and the sliding rod 62 will slide along the air hole 52 under the extrusion of the strip steel. At this time, the elastic sheet 6 will bend under the extrusion of the sliding rod 62, and the shielding area of the elastic sheet 6 for the air hole 52 will also decrease, so that the air flow rate at the air hole 52 will increase, enhancing the cleaning effect of the air flow on the strip steel.

[0033] Please refer to Figure 6 As shown, a runner 7 is rotatably connected to the middle of the sliding rod 62; the runner 7 is located at the top of the conveying assembly 13; when the sliding rod 62 contacts the strip steel, the runner 7 will also contact and rotate with the strip steel. The runner 7 will reduce the friction between the sliding rod 62 and the strip steel, further reducing the damage to the strip steel surface caused by friction.

[0034] Working principle: Place the steel strip on top of the transport component 13 and start the device. The transport component 13 will transport the steel strip. When the steel strip moves, it will pass through the roller 15. When the steel strip is not in the middle area of ​​the transport component 13, it will come into contact with the pressure plate 18. The pressure plate 18 will be compressed together with the spring 17 under the extrusion of the steel strip. At the same time, the pressure plate 18 will transfer the friction between the steel strip and the fixed plate 16 to make the roller 15 rotate. Then the spring 17 will release the elastic force to make the pressure plate 18 squeeze the steel strip. The steel strip will move under the extrusion of the pressure plate 18 until the pressure on the pressure plate 18 stops. At this time, the steel strip will be in the central area of ​​the transport component 13, and then the steel strip will move to The detection component 14 is used to detect the flatness of the strip steel, and the strip steel that has been detected will be transported to the inside of the material receiving device by the transportation component 13; when it is necessary to detect strip steel of different sizes, the pull rope 2 can be pulled to make the pressure plate 18 move toward the fixed plate 16 under the pulling force of the pull rope 2. At this time, the distance between the pair of pressure plates 18 will change, and the pull rope 2 will move along the circular hole 22 when it moves, and the first convex tooth 23 will move with the pull rope 2 and slide along the surface of the second convex tooth 24. When the pull rope 2 stops moving, the first convex tooth 23 will contact the surface of the second convex tooth 24. At this time, the pull rope 2 will be limited by the friction between the first convex tooth 23 and the second convex tooth 24. When the rope 2 is reset, the rope 2 can be pulled hard to make the first convex tooth 23 slide over the second convex tooth 24 in the opposite direction; when the staff resets the rope 2, if excessive force is used, the rope 2 will move quickly along the circular hole 22. When the rope 2 is about to escape from the circular hole 22, the baffle 3 will come into contact with the circular ring 25. At this time, the rope 2 will stop moving under the pressure between the baffle 3 and the circular ring 25, reducing the situation of the rope 2 escaping from the circular hole 22 when adjusting the position; when the strip steel and the pressure plate 18 come into contact, the ball 4 will also come into contact with the strip steel, and the ball 4 will convert the sliding friction between the strip steel and the pressure plate 18 into rolling friction; during operation, the air pipe 5 can be connected to an external air pump so that the air flow will pass through the air pipe 5 into the connecting plate 19, and then the air flow will enter the interior of the roller 15 and be ejected from the air hole 52. The air flow will reach the surface of the strip and clean it, reducing impurities attached to the surface of the strip; during normal operation, the elastic sheet 6 will block the air hole 52, and when the strip moves to the roller 15, it will contact the slide bar 62. The slide bar 62 will slide along the air hole 52 under the extrusion of the strip. At this time, the elastic sheet 6 will bend under the extrusion of the slide bar 62, and the blocking area of ​​the elastic sheet 6 on the air hole 52 will also be reduced, so that the air flow at the air hole 52 will increase. When the slide bar 62 contacts the strip, the wheel 7 will also contact the strip and rotate, and the wheel 7 will reduce the friction between the slide bar 62 and the strip.
