Description

Technical Field

[0001] This utility model relates to the technical field of steel strip straightening equipment, and more specifically, it relates to a straightening device on a steel strip processing line. Background Technology

[0002] When processing steel strips, it is necessary to straighten the steel strips to make the surface of the steel strips flat and facilitate subsequent processing. Currently, straightening devices are commonly used for straightening. Straightening machines generally use multiple roller groups to straighten the steel strips.

[0003] After the steel strip is straightened, it needs to be cut to the required length according to the usage requirements. Due to the limited space inside the workshop where the steel strip is straightened, the steel strip is cut during the straightening process. When cutting the steel strip, people measure and mark the length of the steel strip before cutting. The cutting time is relatively long, which affects the efficiency of the steel strip straightening.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a straightening device for steel strip processing lines, which has the following beneficial effects:

[0017] 1. The steel strip is straightened by the cooperation of multiple rotating rollers and multiple pressure rollers. The distance between the positioning plate and the cutting mechanism is adjusted according to the required length of the steel strip to be cut. This ensures that after the positioning plate presses against the normally closed push switch, the length between the side end of the positioning plate and the cutting mechanism is equal to the length of the steel strip to be cut. When the straightened steel strip contacts the positioning plate, it pushes the positioning plate to move, and the positioning plate presses against the normally closed push switch. When the normally closed push switch is opened, the circuit of the drive mechanism is disconnected, thus stopping the drive mechanism from rotating the multiple rotating rollers. Then, the steel strip is cut by the cutting mechanism. This avoids the need for manual measurement and marking of the steel strip before cutting, saving time on steel strip cutting and thus saving time on steel strip straightening, improving the efficiency of steel strip straightening.

[0018] 2. By setting multiple convex grooves on the fixed plate, the distance between the two positioning rollers is adjusted by sliding the two convex seats inside the convex grooves, so that the distance between the two positioning rollers is equal to the width of the steel strip to be straightened. The multiple positioning rollers facilitate the positioning of the steel strip, prevent the steel strip from tilting, and ensure the straightening effect of the steel strip.

[0019] 3. The two sliding columns and the positioning plate are fixed by the third hydraulic cylinder. When the cut steel strip is taken out, the positioning plate is prevented from separating from the normally closed push switch, the straightened steel strip transmitted from inside the cutting mechanism is prevented from affecting people's handling of the cut steel strip, and injury to the workers is prevented.

[0029] Please see Figure 1-Figure 5A straightening device for a steel strip processing line includes a first fixed frame 1 and a second fixed frame 2. Multiple rotating rollers 3 are rotatably connected to the first fixed frame 1, and a drive mechanism for rotating the multiple rotating rollers 3 is installed on the first fixed frame 1. The second fixed frame 2 is fixedly installed on the first fixed frame 1, and multiple first hydraulic cylinders 4 are installed on the second fixed frame 2. A fixed plate 5 is fixedly connected to the bottom end of the telescopic rod of the multiple first hydraulic cylinders 4, and multiple pressure rollers 6 are rotatably connected to the bottom end of the fixed plate 5. A cutting table 7 is fixedly connected to the side end of the first fixed frame 1, and a cutting mechanism is installed on the cutting table 7. A U-shaped seat 8 is slidably arranged on the cutting table 7. Both ends of the cutting table 7 are provided with sliding grooves 23, and sliding blocks 24 are slidably arranged inside each of the two sliding grooves 23. Both sliding blocks 24 are fixedly connected to the U-shaped seat 8, and both sliding blocks 24 are threaded with first screws 25. The sliding of the sliding blocks 24 within the sliding grooves 23 facilitates the adjustment of the positions of the U-shaped seat 8 and the positioning plate 10. Tightening the first screws 25... Screw 25 is used to abut the side end of the first screw 25 against the side end of the convex groove 26, facilitating the fixing of the slide block 24 and the U-shaped seat 8. Two sliding pillars 9 are slidably arranged on the U-shaped seat 8. A positioning plate 10 is fixedly connected to the end of the two sliding pillars 9 near the cutting mechanism. Multiple compression springs 11 are connected between the positioning plate 10 and the U-shaped seat 8. A limit plate 12 is fixedly connected to the end of each of the two sliding pillars 9 away from the positioning plate 10, thereby limiting the sliding pillars 9 and preventing them from sliding out of the U-shaped seat 8. The U-shaped base 8 slides out, and a normally closed push switch 13 is installed on one end of the U-shaped base 8 near the positioning plate 10. Limit blocks 22 are fixedly connected to the side ends of the two sliding pillars 9, which limit the movement of the two sliding pillars 9 and the positioning plate 10. When the positioning plate 10 presses the normally closed push switch 13 to open it, the side end of the limit block 22 contacts the side end of the U-shaped base 8, preventing the positioning plate 10 from continuing to press the normally closed push switch 13 and preventing the normally closed push switch 13 from being damaged.

[0030] Specifically, four first hydraulic cylinders 4 drive the fixed plate 5 and multiple pressure rollers 6 to move up and down, adjusting the height of the multiple pressure rollers 6. The distance between the pressure rollers 6 and the rotating rollers 3 is adjusted according to the thickness of the steel strip. The steel strip is straightened through the cooperation of the multiple rotating rollers 3 and the multiple pressure rollers 6. The distance between the positioning plate 10 and the cutting mechanism is adjusted according to the required length of the steel strip to be cut, so that after the positioning plate 10 presses the normally closed push switch 13, the length between the side end of the positioning plate 10 and the cutting mechanism is equal to the length of the steel strip to be cut. When the straightened steel strip contacts the positioning plate 10, it pushes the positioning plate 10 to move, and the positioning plate 10 presses the normally closed push switch 13. When the normally closed push switch 13 is opened... After switch 13 is disconnected, the circuit of the drive mechanism is disconnected, thereby stopping the drive mechanism from rotating multiple rollers 3. Then, the steel strip is cut by the cutting mechanism, which avoids the need for manual measurement and marking of the steel strip before cutting, saving the time for cutting the steel strip and thus saving the time for straightening the steel strip, improving the efficiency of straightening the steel strip. Multiple convex grooves 26 are set on the fixed plate 5. By sliding the two convex seats 27 inside the convex grooves 26, the distance between the two positioning rollers 28 is adjusted so that the distance between the two positioning rollers 28 is equal to the width of the steel strip to be straightened. Multiple positioning rollers 28 facilitate the positioning of the steel strip, prevent the steel strip from tilting, and ensure the effect of straightening the steel strip.

[0031] Please see Figure 1 and Figure 2 The drive mechanism includes a motor 14, which is connected in series with the normally closed push switch 13. The motor 14 is mounted on the first fixed frame 1, and the output end of the motor 14 is connected to the corresponding rotating roller 3. The rear ends of the multiple rotating rollers 3 are all fixedly connected to the first gear 15. The rear ends of the first fixed frame 1 are rotatably connected to multiple second gears 16, and the second gears 16 mesh with the two corresponding first gears 15.

[0032] Specifically, the motor 14 drives the corresponding roller 3 and the first gear 15 to rotate. Multiple second gears 16 mesh with multiple first gears 15 to make multiple rollers 3 rotate synchronously. The rotation of the rollers 3 conveys the steel belt that needs to be straightened.

[0033] Please see Figure 1 and Figure 4 The cutting mechanism includes a cutting blade 17. An L-shaped seat 18 is fixedly connected to the top end of the cutting table 7 near the first fixed frame 1. A through groove 19 is provided on the L-shaped seat 18. Two second hydraulic cylinders 20 are installed on the L-shaped seat 18. The cutting blade 17 is fixedly connected to the bottom end of the telescopic rod of the two second hydraulic cylinders 20.

[0034] Specifically, the second hydraulic cylinder 20 pushes the cutting blade 17 downward to cut the steel strip.

[0035] Please see Figure 1 and Figure 5 Each position on the U-shaped seat 8 corresponding to the sliding column 9 is equipped with a third hydraulic cylinder 21 that cooperates with the sliding column 9, so as to facilitate the fixing of the sliding column 9 and the positioning plate 10.

[0036] Specifically, the two sliding columns 9 and the positioning plate 10 are fixed by the third hydraulic cylinder 21. When the cut steel strip is taken out, the positioning plate 10 is prevented from separating from the normally closed push switch 13, the straightened steel strip transmitted from inside the cutting mechanism is prevented from affecting people's handling of the cut steel strip, and injury to the staff is avoided.

[0037] Please see Figure 3 The bottom end of the fixing plate 5 is evenly provided with a plurality of convex grooves 26. Two convex seats 27 are slidably arranged inside each convex groove 26. Positioning rollers 28 are rotatably connected to each of the two convex seats 27. A plurality of positioning grooves 29 are evenly provided at the top end of the convex grooves 26. A second screw 30 that mates with the positioning groove 29 is threaded onto the convex seat 27. Tightening the second screw 30 causes the top end of the second screw 30 to be inserted into the corresponding positioning groove 29, which facilitates the fixing of the convex seat 27 and the positioning roller 28.

[0038] Specifically, the position of the positioning roller 28 is adjusted by sliding the convex seat 27 inside the convex groove 26. The spacing between the two corresponding positioning rollers 28 is adjusted according to the width of the steel strip. Then, the second screw 30 is tightened so that the top of the second screw 30 is inserted into the corresponding positioning groove 29 to fix the convex seat 27 and the positioning roller 28. The straightened steel strip is positioned by multiple positioning rollers 28, which makes it easier for the steel strip to move in a direction perpendicular to the rotating roller 3 and the pressure roller 6, and avoids the steel strip tilting.

[0039] In summary, when using the overall equipment:

[0040] Four first hydraulic cylinders 4 drive the fixed plate 5 and multiple pressure rollers 6 to move up and down, adjusting the height of the multiple pressure rollers 6. The distance between the pressure rollers 6 and the rotating roller 3 is adjusted according to the thickness of the steel strip. The position of the positioning roller 28 is adjusted by sliding the convex seat 27 inside the convex groove 26. The distance between the corresponding two positioning rollers 28 is adjusted according to the width of the steel strip. Then, the second screw 30 is tightened so that the tip of the second screw 30 is inserted into the corresponding positioning groove 29, fixing the convex seat 27 and the positioning roller 28. The slide 24 slides inside the slide groove 23, adjusting the position of the U-shaped seat 8 and the positioning roller 28. The position of plate 10 is adjusted so that the sum of the distance between the positioning plate 10 and the side end of the cutting blade 17 and the distance between the limiting block 22 and the U-shaped seat 8 is equal to the length of the steel strip to be cut. Then, the first screw 25 is tightened so that the side end of the first screw 25 abuts against the side end of the slide groove 23, fixing the slide 24 and the U-shaped seat 8. Then, the steel strip to be straightened is inserted into the middle of the pressure roller 6, the rotating roller 3 and the multiple positioning rollers 28 on both sides. At the same time, the motor 14 is started, which drives the corresponding rotating roller 3 and the first gear 15 to rotate. Multiple second gears 16 mesh with multiple first gears 15 in an alternating manner. Multiple rotating rollers 3 rotate synchronously, causing the steel strip to move towards the side closer to the cutting table 7. The steel strip is straightened through the cooperation of multiple rotating rollers 3 and multiple pressure rollers 6. The straightened steel strip passes through the slot 19 on the L-shaped seat 18. When the side end of the steel strip contacts the positioning plate 10, the positioning plate 10 continues to move, pressing the normally closed push switch 13. When the normally closed push switch 13 is opened, the circuit connected to the motor 14 is disconnected, and the motor 14 stops working. At this time, the side end of the limit block 22 contacts the side end of the U-shaped seat 8, and the length of the steel strip on the cutting table 7 is the required length. Then, the sliding column 9 is pressed and fixed by the third hydraulic cylinder 21. Then, the cutting blade 17 is pushed downward by the two second hydraulic cylinders 20 to cut the steel strip. Then, the cut steel strip is removed from the cutting table 7. Then, the third hydraulic cylinder 21 is contracted, so that the telescopic rod of the third hydraulic cylinder 21 is separated from the sliding column 9. The positioning plate 10 is pushed to move by the compression spring 11, so that the positioning plate 10 is separated from the normally closed push switch 13. The normally closed push switch 13 is closed, the circuit of the motor 14 is connected, the motor 14 works, and continues to straighten the steel strip. This process of straightening and cutting the steel strip is repeated.
