Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of strip steel slitting machines, and in particular, to a hydraulic centering guide device for a strip steel slitting machine unit. Background Art

[0002] After production, the steel strips are all in the form of wider coils. When a narrower steel strip is needed during use, it is necessary to cut the steel strip longitudinally. At this time, the equipment needed is a strip slitting unit. The rolled steel strip is conveyed to the slitting unit, and after the strip is aligned, the rotating cutter cuts the steel strip into the required width and reels it to obtain multiple narrow steel strip rolls.

[0003] Before the strip is conveyed to the slitting unit, it needs to be straightened by a leveling device to eliminate the stress during curling and keep it flat for easy slitting. A large space is left between the leveling device and the slitting unit. The steel strip may shake due to external airflow during operation, causing the strip to shift, so it is necessary to align the strip before slitting. In existing slitting units, the strip is mostly driven by multiple rollers to move. Manual adjustment is still required when aligning the strip, which reduces production efficiency and has low centering accuracy. Therefore, a guide device that can accurately and quickly center the strip is needed. Summary of the invention

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1 to Figure 7 As shown, it shows a hydraulic centering guide device of a strip steel slitting unit in an embodiment of the present disclosure, including a frame, a receiving roller 3, a clamping guide mechanism, a leveling mechanism, a V-shaped slide groove and a spiral pushing mechanism. The frame is arranged to be composed of a frame 1 and a frame 2 2 that are fixedly connected. A plurality of receiving rollers 3 are arranged, and the plurality of receiving rollers 3 are connected to the frame 1 in a fan-shaped rotation. The clamping guide mechanism is fixedly arranged on the frame 1, and the clamping guide mechanism is slidably connected to the receiving roller 3. The clamping guide mechanism is used to clamp and limit the strip steel at the contact position with the receiving roller 3. A plurality of leveling mechanisms are arranged, and the plurality of leveling mechanisms are arranged on the frame 2 2. The leveling mechanism is used to In order to extrude and level the strip, a V-shaped slide is opened on the frame 2, the V-shaped slide is arranged between multiple leveling mechanisms, and a spiral pushing mechanism is arranged on the frame 2. The spiral pushing mechanism is slidably connected to the V-shaped slide, and the spiral pushing mechanism is used to push the strip laterally. Both the spiral pushing mechanism and the clamping guide mechanism can push the strip. Most of the existing guiding devices push the strip to move through one position, which may cause the edge of the strip to be squeezed and deformed or the strip to deflect and tilt. Therefore, the two-layer structure can push the strip to make the strip offset, and at the same time, the offset strip is kept vertically aligned with the slitting unit.

[0024] like Figure 3~Figure 4As shown, the two oblique sides of the V-shaped slide are symmetrically arranged, and an oblique track 4 is arranged on the oblique sides. A circular receiving hole 5 is arranged in the center of the V-shaped slide. The receiving hole 5 in the center of the V-shaped slide will not contact the slide frame. When the parallel push rod 7 and the threaded sleeve 8 extrude the strip steel, the receiving hole 5 is arranged to prevent the slide frame from being limited, and the parallel push rod 7 is supported by the slide frame.

[0025] like Figure 1 to Figure 6 As shown, the spiral pushing mechanism includes a fixed frame 6, a parallel push rod 7, a gear 1 9, a gear 2 10, an exchange component and a transmission component, and two are provided. The fixed frame 6 is arranged on the side of the frame 2, and two parallel push rods 7 are provided. The two ends of the two parallel push rods 7 are respectively rotatably connected with a fixed frame 6. The two parallel push rods 7 are both sleeved with a rubber threaded sleeve 8. The threads on the two threaded sleeves 8 rotate in opposite directions. The parallel push rods 7 pass through the V-shaped slide groove. The two ends of the parallel push rods 7 are fixedly connected with a gear 1 9, and the gear 1 9 contacts the fixed frame 6. Each fixed frame 6 is rotatably connected with a gear 2 10, and the gear 2 10 is arranged A driving wheel 11 is fixedly connected between the two gears 19 and meshed with the two gears 19 on the side of the gear 2 10 away from the parallel push rod 7. The exchange component is arranged on the frame 2 2. The exchange component is rotatably connected to the parallel push rod 7. The exchange component is used to drive the two parallel push rods 7 to contact the strip steel respectively. The transmission component is fixedly arranged on the frame 2 2. The transmission component is connected to the driving wheel 11. The transmission component is used to drive the two parallel push rods 7 to rotate. The two parallel push rods 7 are driven to rotate in the same direction through the transmission component. The two parallel push rods 7 can be pushed toward the strip steel respectively through the exchange component, and the exchange is performed according to the direction in which the strip steel is pushed to move.

[0026] like Figure 2~Figure 6As shown, the exchange component includes a sliding frame 12 and a driving cylinder 13, which are respectively rotatably connected to the two parallel push rods 7, and the sliding frame 12 is slidably connected in the inclined track 4. There are two driving cylinders 13, which are fixedly set on the frame 2, and the output end of the driving cylinder 13 is fixedly connected to the sliding frame 12. When the output ends of the two driving cylinders 13 are respectively extended and shortened, the two parallel push rods 7 can be driven to move in the V-shaped slide groove through the sliding frame 12. Two supporting rollers 14 are rotatably connected to the frame 2, and the two supporting rollers 14 are respectively set on both sides below the accommodating hole 5. When the parallel push rod 7 moves into the accommodating hole 5, the threaded sleeve 8 and the two supporting rollers 14 squeeze the strip. For the convenience of explanation, the base 1 is set to the left side and the bottom Seat two is set to the right side. When the output end of the left driving cylinder 13 is shortened and the output end of the right driving cylinder 13 is extended, the sliding frame 12 and the parallel push rod 7 on the left side can be pulled to slide upward along the inclined track 4 and separate from the strip. At this time, the sliding frame 12 and the parallel push rod 7 on the right side move downward along the inclined track 4. When the parallel push rod 7 on the right side moves into the accommodating cavity, it is located between the two supporting rollers 14. The threaded sleeve 8 is squeezed with the strip, and when rotating, the thread pushes the strip to one side. Through the contact between the thread and the strip, the friction force can be used to push the strip to deflect on the surface of the strip, thereby avoiding damage to the edge of the strip. The force area is larger and the pushing effect is better. Moreover, since the threads on the two threaded sleeves 8 are in opposite directions, the strip can be pushed to move in two directions respectively.

[0027] like Figure 3~Figure 5 As shown, the transmission assembly includes a transmission seat 15 and a transmission wheel 16. The transmission seat 15 is fixedly connected to the frame 2, and the transmission seat 15 is arranged below the accommodating hole 5. The transmission wheel 16 is rotatably connected to the transmission seat 15. The transmission seat 15 and the accommodating hole 5 are arranged coaxially. The transmission wheel 16 and the drive wheel 11 are tensioned with a transmission belt 17. A motor 26 is installed on the side of the base 2. The output end of the motor 26 is connected to the transmission wheel 16. When the output end of the motor 26 drives the transmission wheel 16 to rotate, the transmission wheel 16 drives the drive wheel 11 to rotate through the transmission belt 17, and the drive wheel 11 drives the gear 2 10 to rotate. The second gear 10 can drive the two gears 1 9 to rotate in the same direction, and then the two parallel push rods 7 can rotate in the same direction and rotate in the direction of movement of the steel strip. The threaded sleeve 8 drives the steel strip to move. At the same time, the friction between the thread and the steel strip pushes the steel strip to move in parallel. After the steel strip moves to the center position, the threaded sleeve 8 separates from the steel strip, and the two parallel push rods 7 slide in the inclined track 4. At this time, the fixed frame 6 moves with the parallel push rods 7, and the gear 2 10 performs a circular motion with the accommodating cavity as the center, so that when the parallel push rods 7 move, the transmission belt 17 will rotate with the gear 2 10 while maintaining the transmission to the driving wheel 11.

[0028] like Figure 1 and Figure 7 As shown, two clamping guide mechanisms are provided, and the two clamping guide mechanisms are respectively arranged on both sides of the receiving roller 3 in opposite directions. The clamping guide mechanism includes a driving cylinder 18 and a clamping plate 19. There are multiple driving cylinders 18, and multiple driving cylinders 18 are fixedly installed on the frame 1. The receiving roller 3 passes through the clamping plate 19, and the clamping plate 19 is connected to the output end of the driving cylinder 18. A pressing arc 20 is fixedly connected to the end of the clamping plate 19 away from the frame 2. The output end of the driving cylinder 18 drives the clamping plate 19 to slide, which can push the strip sliding on the receiving roller 3 to move. At the same time, the pressing arc 20 can prevent the strip from being scratched by the edge of the clamping plate 19 when it shakes, thereby damaging the strip.

[0029] like Figure 1 and Figure 6 As shown, the leveling mechanism includes a vertical rail 21, a clamping block 22, a flattening wheel 24 and a driving cylinder 3 25. The vertical rail 21 is opened on the frame 22, the clamping block 22 is slidably set on the vertical rail 21, and the clamping block 22 is rotatably connected with a flattening wheel 1 23. There are multiple flattening wheels 24, and the multiple flattening wheels 24 are rotatably set on the frame 22 and are set below the vertical rail 21. The driving cylinder 3 25 is fixedly installed on the frame 22, and the output end of the driving cylinder 3 25 is fixedly connected to the clamping block 22. The steel strip is squeezed by the leveling mechanism, so that the strip can be bent three times. The internal stress of the strip when it is rolled is eliminated by repeatedly bending the strip. When the strip is driven to move, the output end of the driving cylinder 3 25 is extended to reduce the squeezing force of the flattening wheel 1 23 on the steel strip, which is convenient for the displacement of the steel strip.

[0030] In some examples, the steel belt moves on the receiving roller 3, and the steel belt passes between the flattening wheel 1 23 and the flattening wheel 2 24, and between the parallel push rod 7 and the supporting roller 14. When the centering adjustment of the strip is required, the output end of the driving cylinder 2 18 is shortened to increase the distance between the flattening wheel 1 23 and the flattening wheel 2 24, thereby reducing the pressure on the strip. The output ends of the two driving cylinders 13 are respectively extended and shortened, so that the corresponding threaded sleeves 8 are in contact with the strip. The output end of the motor 26 drives the transmission wheel 16 to rotate, and the transmission wheel 16 drives the driving wheel 11 to rotate through the transmission belt 17. The gear 2 10 drives the two gears 1 9 to rotate in the same direction. When the threaded sleeve 8 is in contact with the strip, the rotation of the parallel push rod 7 causes the threaded sleeve 8 to push the strip to translate. The driving cylinders 2 18 on both sides of the receiving roller 3 are respectively extended and shortened to drive the clamping plate 19 to move, thereby pushing the strip to slide.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
