Description

Technical Field

[0001] The invention relates to the technical field of steel strip deviation correction, in particular to a steel strip production deviation correction mechanism and a deviation correction method thereof. Background Art

[0002] The steel belt production correction mechanism plays a vital role in the steel belt production process. It is mainly used to ensure that the steel belt always maintains the correct position on the production line to improve product quality and production efficiency. It ensures that the steel belt always runs in a straight line during the production process to avoid defects such as uneven and wavy steel belt edges caused by deviation, so as to make the product size more accurate.

[0003] The existing patent (publication number: CN 117819273 B) discloses a steel strip deviation correction mechanism and a deviation correction method on a steel strip manufacturing line, which relates to the field of steel strip winding and conveying, including a rolled steel strip and a winding machine for winding the rolled steel strip, and two sets of leveling rollers for leveling the upper and lower end surfaces of the rolled steel strip are also arranged on the outside of the rolled steel strip; a deviation correction guide mechanism is used to correct the rolled steel strip, and the deviation correction guide mechanism is arranged on the side of the leveling roller away from the winding machine. The steel strip deviation correction mechanism on the steel strip manufacturing line, through the two V-shaped guide wheels in the deviation correction guide mechanism that roll along with the displacement of the rolled steel strip, rolls the two sides of the rolled steel strip. The limiting treatment replaces the static friction correction limit in the prior art and uses a rolling correction limit. It can prevent the burrs on the side of the rolled steel strip from easily causing wear of the correction structure, and can also prevent the correction structure from restricting the rolled steel strip too tightly, causing deformation of the rolled steel strip. However, in the actual production process, in order to ensure efficiency, the produced steel strip needs to be die-cast to form a concave shape, and manual straightening and correction are required before pressing to ensure that the die-casting effect meets the standards. In addition, the newly produced steel strip will be in a state of bending up and down or left and right, so a steel strip production correction mechanism is needed. Summary of the invention

[0010] Preferably, the clamping rod is slidably connected inside the oblique groove plate.

[0011] A deviation rectifying method for a deviation rectifying mechanism in steel strip production includes the following steps:

[0012] S1. First, start the straightening machine body and put the steel strip into one end of the vertical electric roller of the straightening machine body. After passing through two electric rollers, the steel strip enters the next two electric rollers through the conveyor belt. At the same time, when the vertical electric roller rotates, it is transmitted to the rotating rod through the first transmission belt. When the rotating rod rotates, it drives the inclined rod to rotate. When the inclined rod rotates, it drives the semi-circular plate to rotate on the surface of the rotating rod. At the same time, the rotating frame outside the rotating rod is limited. When the rotating rod needs to rotate, the rotating frame swings left and right around the center point positions on both sides. When the rotating frame swings, it drives the pressing rods on both sides to move up and down alternately inside the limiting chute and squeeze the steel strip, correcting and straightening the newly produced steel strip.

[0013] S2. After the steel strip comes out of the straightening machine body, it enters the surface of the electric conveyor belt and is transported to the next process. When the electric conveyor belt works, it drives the driven wheel to rotate. When the driven wheel rotates, it drives the worm to rotate through the second transmission belt. When the worm rotates, it drives the engaged turbine to rotate. When the turbine rotates, it drives the L-shaped rotating rod at the other end to rotate. When the L-shaped rotating rod rotates, it will squeeze the blocking rod. When the blocking rod is squeezed, it will drive the slider to slide towards one end inside the chute. After the L-shaped rotating rod rotates half a circle and starts the other half circle, it will squeeze one end of the double L-shaped rotating rod. When the double L-shaped rotating rod is squeezed, it will start to rotate through the torsion spring rod. When the double L-shaped rotating rod rotates, the other end will squeeze the blocking rod, and the blocking rod will drive the slider to slide towards the other end inside the chute. When the L-shaped rotating rod passes the double L-shaped rotating rod, the double L-shaped rotating rod will reset through the torsion spring rod and be blocked by the limiting rod. In this way, when the L-shaped rotating rod continues to rotate, the slider will slide left and right reciprocally inside the chute and drive the inclined chute plate to move at the same time.

[0014] S3. When the inclined chute plate moves, it will squeeze the clamping rod and displace along the track of the inclined chute inside the inclined chute plate through the rotating wheel. At the same time, the rotating wheel rotates. When the rotating wheel rotates, it will pull two connecting rods to drive the large pushing plate to move relatively on the side of the numerical control machine tool and correct the steel strip. When the inclined chute plate moves in the reverse direction, it will drive the small pushing plate to squeeze and correct the steel strip. The small pushing plate slides inside the large pushing plate and corrects the steel strip through the gap of the large pushing plate. In this way, the steel strip will be continuously squeezed and corrected. When the inclined chute plate moves in the reverse direction, it will drive the clamping rod to reset along the straight track. Similarly, the inclined chute plate on the other side will drive the small pushing plate to squeeze and correct the steel strip.

[0015] S4. After reaching the specified position, the electric conveyor belt and the straightening machine body stop operating, and at the same time, the double-shaft motor is started. When the double-shaft motor starts, it drives the eccentric wheel to rotate. When the eccentric wheel rotates, it drives the L-shaped notch rod to rotate outward with the lower end of the clamping plate as the center. It will stop rotating after rotating 90 degrees. When the L-shaped notch rod rotates, it drives the clamping plate to rotate. The two clamping plates rotate towards the surface of the steel belt at the same time. At the same time, when the clamping plate rotates, the connecting rod will pull the clamping plate and move towards the center position of the clamping plate. At the same time, when the clamping plate moves, it will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the other clamping plate to move at the same time. The two clamping plates move inward at the same time to fix the steel belt at the center point position.

[0016] In the present invention, when the inclined groove plate moves, it will squeeze the clamping rod and displace along the track of the inclined groove inside the inclined groove plate through the rotating wheel. At the same time, the rotating wheel rotates. When the rotating wheel rotates, it will pull the two connecting rods to drive the large push plate to move relatively on the side of the numerical control machine tool and correct the steel belt to prevent deviation during transportation.

[0017] In the present invention, when the rotating rod rotates, the rotating frame swings left and right from the center points on both sides. When the rotating frame swings, it drives the pressing rods on both sides to move up and down alternately inside the limit sliding groove and squeeze the steel belt to straighten and correct the newly produced steel belt to prevent deviation in the next process.

[0018] In the present invention, when the clamping plate moves, it will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the other clamping plate to move at the same time. The two clamping plates move inward at the same time to fix the steel belt at the center point position to ensure that the position of the next process is at the center point.

[0037] The usage method and advantages of the present invention: For this steel belt production deviation rectifying mechanism and its deviation rectifying method, during use, the working process is as follows:

[0038] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 shown;

[0039] A deviation rectifying method for a steel belt production deviation rectifying mechanism includes the following steps:

[0040] S1. First, start the straightening machine body 21 and put the steel belt into one end of the vertical electric roller 22 of the straightening machine body 21. After the steel belt passes through the two electric rollers 22, it enters the next two electric rollers 22 through the conveyor belt 4. At the same time, when the vertical electric roller 22 rotates, it is transmitted to the rotating rod 51 through the first transmission belt 23. When the rotating rod 51 rotates, it drives the inclined rod 52 to rotate. When the inclined rod 52 rotates, it drives the semi-circular plate 55 to rotate on the surface of the rotating rod 54. At the same time, the rotating frame 53 outside the rotating rod 54 is limited. When the rotating rod 54 needs to rotate, the rotating frame 53 sways left and right from the center point positions on both sides. When the rotating frame 53 swings, it drives the pressing rods 57 on both sides to move up and down alternately inside the limit sliding groove 56 and squeeze the steel belt, correcting and straightening the newly produced steel belt to prevent deviation in the next process;

[0041] S2. After the steel strip comes out of the straightening machine body 21 and enters the surface of the electric conveyor belt 3 for transportation to the next process. When the electric conveyor belt 3 operates, it drives the driven wheel to rotate. When the driven wheel rotates, it drives the worm 61 to rotate through the second transmission belt 62. When the worm 61 rotates, it drives the meshing turbine 63 to rotate. When the turbine 63 rotates, it drives the L-shaped rotating rod 67 at the other end to rotate. When the L-shaped rotating rod 67 rotates, it will squeeze the shift lever 66. When the shift lever 66 is squeezed, it will drive the slider 65 to slide towards one end inside the chute 64. And after the L-shaped rotating rod 67 rotates half a circle, when it starts the other half circle, it will squeeze one end of the double L-shaped rotating rod 68. When the double L-shaped rotating rod 68 is squeezed, it will start to rotate through the torsion spring rod. When the double L-shaped rotating rod 68 rotates, the other end will squeeze the shift lever 66, and the shift lever 66 will drive the slider 65 to slide towards the other end inside the chute 64. And when the L-shaped rotating rod 67 passes the double L-shaped rotating rod 68, the double L-shaped rotating rod 68 will reset through the torsion spring rod and be blocked by the limiting rod 69 at the same time. In this way, when the L-shaped rotating rod 67 continues to rotate, the slider 65 will slide back and forth left and right inside the chute 64, and at the same time will drive the inclined chute plate 610 to move at the same time;

[0042] S3. When the inclined chute plate 610 moves, it will squeeze the clamping rod 72 and displace along the trajectory of the inclined chute inside the inclined chute plate 610 through the runner 71. At the same time, the runner 71 rotates. When the runner 71 rotates, it will pull the two connecting rods 73 to drive the large push plate 74 to move relatively on the side of the numerical control machine tool 1 and correct the steel strip to prevent deviation during transportation. When the inclined chute plate 610 moves in the reverse direction, the moving small push plate 75 squeezes and corrects the steel strip, and the small push plate 75 slides inside the large push plate 74 and corrects the steel strip from the gap of the large push plate 74. In this way, the steel strip will be continuously squeezed and corrected. When the inclined chute plate 610 moves in the reverse direction, it will drive the clamping rod 72 to reset along the straight line trajectory. Similarly, the inclined chute plate 610 on the other side will drive the small push plate 75 to squeeze and correct the steel strip, and it will not be misaligned due to the vibration generated by the machine itself;

[0043] S4. After reaching the specified position, the electric conveyor belt 3 and the straightening machine body 21 stop operating, and at the same time the double-shaft motor 82 is started. When the double-shaft motor 82 is started, it drives the eccentric wheel 83 to rotate. When the eccentric wheel 83 rotates, it drives the L-shaped notch rod 89 to start rotating outward with the lower end of the clamping plate 84 as the center, and stops rotating after rotating 90 degrees. When the L-shaped notch rod 89 rotates, it drives the clamping plate 84 to rotate. The two clamping plates 84 rotate towards the surface of the steel strip at the same time. At the same time, when the clamping plate 84 rotates, the connecting rod 88 will pull the clamping plate 85 and move towards the center position of the clamping plate 84. At the same time, when the clamping plate 85 moves, it will drive the threaded rod 86 to rotate. When the threaded rod 86 rotates, it will drive the other clamping plate 85 to move at the same time. The two clamping plates 85 move inward at the same time to fix the steel strip at the center point position to ensure that the position of the next process is at the center point.

5. The method for correcting the deviation of a steel strip production correcting mechanism according to claim 4, characterized in that: The following steps are involved: S1. First, the straightening machine body (21) is started and the steel strip is placed from one end of the vertical electric roller (22) of the straightening machine body (21). After the steel strip passes through the two electric rollers (22), it passes through the conveyor belt (4) and enters the next two electric rollers (22). At the same time, when the vertical electric roller (22) rotates, it is transmitted to the rotating rod (51) through the transmission belt 1 (23). When the rotating rod (51) rotates, it drives the inclined rod (52) to rotate. When the inclined rod (52) rotates, it drives the semicircular plate (55) to rotate on the surface of the rotating rod (54). At the same time, the rotating frame (53) outside the rotating rod (54) is limited. When the rotating rod (54) needs to rotate, the rotating frame (53) swings left and right from the center point position on both sides. When the rotating frame (53) swings, it drives the pressure rods (57) on both sides to move up and down in an interlaced manner inside the limiting slide groove (56), and squeezes the steel strip, so as to correct and straighten the newly produced steel strip; S2. After the steel strip comes out of the straightening machine body (21), it enters the surface of the electric conveyor belt (3) and is transported to the next process. When the electric conveyor belt (3) is working, it drives the driven wheel to rotate. When the driven wheel rotates, it drives the worm (61) to rotate through the transmission belt 2 (62). When the worm (61) rotates, it drives the meshing turbine (63) to rotate. When the turbine (63) rotates, it drives the L-shaped rotating rod (67) at the other end to rotate. When the L-shaped rotating rod (67) rotates, it squeezes the gear rod (66). When the gear rod (66) is squeezed, it drives the slider (65) to slide to one end inside the slide groove (64). After the L-shaped rotating rod (67) rotates half a circle, it starts When the double L-shaped rotating rod (68) starts to rotate, one end of the double L-shaped rotating rod (68) is squeezed. When the double L-shaped rotating rod (68) is squeezed, it starts to rotate through the torsion spring rod. When the double L-shaped rotating rod (68) rotates, the other end squeezes the shift rod (66), and the shift rod (66) drives the slider (65) to slide toward the other end in the slide groove (64). When the L-shaped rotating rod (67) rotates past the double L-shaped rotating rod (68), the double L-shaped rotating rod (68) is reset through the torsion spring rod and is blocked by the limit rod (69). In this way, when the L-shaped rotating rod (67) continues to rotate, the slider (65) will slide back and forth inside the slide groove (64), and at the same time, the inclined groove plate (610) will be driven to move at the same time; S3, when the inclined slot plate (610) moves, the clamping rod (72) is squeezed and displaced through the rotating wheel (71) along the track of the inclined slot inside the inclined slot plate (610), and at the same time the rotating wheel (71) rotates. When the rotating wheel (71) rotates, it pulls the two connecting rods (73) to drive the large push plate (74) to move relatively on the side of the CNC machine tool (1) and correct the steel belt. When the inclined slot plate (610) moves in the opposite direction, the small push plate (75) is driven to squeeze and correct the steel belt, and the small push plate (75) slides inside the large push plate (74) to correct the steel belt through the gap of the large push plate (74). In this way, the clamping rod (72) is driven to reset along the straight track while the steel belt is continuously squeezed and corrected. Similarly, the inclined slot plate (610) on the other side drives the small push plate (75) to squeeze and correct the steel belt. S4. After reaching the designated position, the electric conveyor belt (3) and the straightening machine body (21) stop operating, and the double-axis motor (82) is started at the same time. When the double-axis motor (82) is started, the eccentric wheel (83) is driven to rotate. When the eccentric wheel (83) rotates, it drives the L-shaped notch rod (89) to start rotating outward with the lower end of the clamping plate (84) as the center. The rotation stops after ninety degrees. When the L-shaped notch rod (89) rotates, it drives the clamping plate (84) to rotate. The two clamping plates (84) rotate toward the surface of the steel strip at the same time. When the clamping plate (84) rotates, the connecting rod (88) pulls the clamping plate (85) and moves toward the center position of the clamping plate (84). When the clamping plate (85) moves, it drives the threaded rod (86) to rotate. When the threaded rod (86) rotates, it drives another clamping plate (85) to move at the same time. The two clamping plates (85) move inward at the same time to fix the steel strip at the center point.
