Description

Technical Field

[0001] This invention relates to the field of steel coil leveling technology, specifically to an automated steel coil unwinding and leveling device for steel pipe production. Background Technology

[0002] In the steel pipe production process, unwinding and leveling of steel coils are crucial preliminary steps. After winding, the ends of the steel coil are typically fixed to the coil rollers using screws, clamps, or other structures to ensure stability during the winding process. Before unwinding, the constraints on the exit and initial ends of the steel coil must be released, and then the coil is pulled onto a conveyor frame for leveling before being sent to subsequent processing steps.

[0003] Currently, most steel coil unwinding and leveling operations rely on manual labor. Operators must manually release the fixing constraints at both ends of the steel coil, then transfer it to a conveyor platform using a crane or forklift, and finally use leveling rollers for initial leveling. This method has the following drawbacks: First, manual constraint release is inefficient and labor-intensive, and operators must be in close contact with the high-speed rotating steel coil rollers, posing safety hazards. Second, the lack of effective limiting measures during the traction of the steel coil to the platform makes it prone to positional deviation, affecting the accuracy of subsequent conveying. Third, existing leveling devices typically only level the exit end of the steel coil, with insufficient coverage of the middle and initial ends, resulting in uneven leveling and causing wrinkles or deviations in subsequent leveling and welding processes, affecting the quality of the finished steel pipe. Fourth, the entire process has a low degree of automation, and the connections between different processes are not smooth, restricting the overall efficiency of steel pipe production.

[0023] Those skilled in the art will understand that by driving the first threaded rod 202 to rotate through the output end of the first servo motor 204, the two sets of movable plates 205 move closer or further apart along the outer wall of the first fixed rod 203, thereby driving the two sets of locking blocks 206 to move closer or further apart.

A movable plate 409 is slidably connected to the second guide rod 407, and the movable plate 409 is threadedly connected to the second lead screw 406. A second stepper motor 408 for driving the second lead screw 406 to rotate is provided on the outer wall of one set of movable parts 405, and a first stepper motor 408 is fixedly installed inside the movable plate 409. The electric actuator 410 has a lifting base 411 fixedly installed at its output end. A first motor 412 is provided on the outer wall of the lifting base 411.

[0029] Those skilled in the art will understand that by synchronously controlling the output ends of the two sets of first stepper motors 404 to rotate, the two sets of first lead screws 402 are driven to rotate synchronously, causing the two sets of moving parts 405 to reciprocate left and right synchronously in the horizontal direction, thereby driving the electric screwdriver bit 416 to reciprocate left and right in the horizontal direction; and by controlling the output end of the second stepper motor 408 to rotate, the second lead screw 406 is driven to rotate, causing the moving plate 409 to reciprocate back and forth along the outer wall of the second guide rod 407, thereby driving the electric screwdriver bit 416 to reciprocate back and forth; and by controlling the output end of the first electric push rod 410 to extend or retract, the electric screwdriver bit 416 is driven to move downward or upward.

Whether in a vertical or horizontal state, the output of the second motor 414 drives the electric screwdriver bit 416 to rotate, while the output of the second electric push rod 415 rotates simultaneously, thus enabling the electric screwdriver bit 416 to rotate and move up and down in a vertical state or rotate and move back and forth in a horizontal state.

[0032] Please refer to Figure 8 As shown, the traction mechanism 5 also includes a second threaded rod 510 and two sets of clamping plates 513.

[0033] Those skilled in the art will understand that by controlling the output of the second servo motor 512 to drive the second threaded rod 510 to rotate, the two sets of clamping plates 513 are brought closer or further apart; by controlling the output of the third stepper motor 504 to drive the third lead screw 502 to rotate, the movable frame 505 moves back and forth horizontally, thereby driving the two sets of clamping plates 513 to move back and forth horizontally; and by controlling the output of the fourth stepper motor 508 to drive the fourth lead screw 506 to rotate, the lifting frame 509 moves back and forth vertically, thereby driving the two sets of clamping plates 513 to move back and forth vertically.

[0042] Those skilled in the art will understand that by controlling the output end of the sixth stepper motor 804 to drive the sixth lead screw 802 to rotate, the lifting component 805 and the leveling roller 806 as a whole will move up and down reciprocally along the outer wall of the sixth guide rod 803.

[0043] To clearly describe the working principle of this invention, we will use... Figure 1 The explanation is based on a directional perspective, as follows: S1. The external robotic arm grips the steel roll assembly 3 and transfers it between the two sets of movable plates 205. The output end of the first servo motor 204 drives the first threaded rod 202 to rotate, so that the two sets of movable plates 205 and the locking blocks 206 move closer to each other. The two sets of locking blocks 206 respectively lock into the slots 303 on the front and rear discs 302 of the steel roll assembly 3, thereby realizing the installation of the steel roll assembly 3. S2. By controlling the output end of the drive motor 207 to rotate, the steel coil discharge end on the steel coil roller assembly 3 is located on the right side. Under the action of the traction mechanism 5, the two sets of clamping plates 513 are located on the upper and lower sides of the middle of the steel coil discharge end. Then the two sets of clamping plates 513 move closer to each other and clamp the middle of the steel coil discharge end. S3. Under the action of the release mechanism 4, the mounting rod 413, the second motor 414, the second electric push rod 415, and the electric screwdriver bit 416 are in a vertical state, which twists the two sets of second screws 306, causing the two sets of second screws 306 and the pressure block 307 to move upward as a whole. The pressure block 307 releases the fixation on the steel coil discharge end. After that, the mounting rod 413, the second motor 414, the second electric push rod 415, and the electric screwdriver bit 416 are in a horizontal state, which twists the two sets of first screws 304, causing the two sets of fixed seats 305 to move away from each other, thereby releasing the constraint on the steel coil discharge end. S4. Under the action of the traction mechanism 5, the steel coil discharge end is driven to move to the right. The lifting frame 509 is located inside the strip groove 102. Then, by controlling the output end of the sixth stepper motor 804 on the left to rotate, the lifting component 805 and the leveling roller 806 on the left move downward as a whole, pressing the steel coil on the top of the frame 101. S5. The two sets of clamping plates 513 release the clamping on the middle of the steel coil discharge end, and the two sets of clamping plates 513 move out of the strip groove 102 and reset. By controlling the output end of the fifth stepper motor 704, the fifth lead screw 702 is driven to rotate, so that the lifting plate 705 moves upward along the outer wall of the fifth guide rod 703. The lifting plate 705 enters the strip groove 102, and the top of the lifting plate 705 is on the same plane as the top of the frame 101. S6. By controlling the output of the third servo motor 603 to drive the third threaded rod 601 to rotate, the two sets of limit plates 604 move closer to each other and limit the front and rear sides of the steel coil at the top of the frame 101, so that the steel coil will not shift its position during subsequent conveying. Then, the leveling roller 806 on the left rotates to convey the steel coil, so that the steel coil is transported to the right along the top of the frame 101. The lifting component 805 and the leveling roller 806 on the right are driven to move downward as a whole in advance. Then, the steel coil is constrained by the leveling roller 806 on the right during the process of being transported to the right, thus achieving leveling. S7. The initial end of the steel coil is fixed between the first half roller 301 and the second half roller 309. The two sets of third screws 308 are twisted by the action of the release mechanism 4, so that the two sets of third screws 308 and the second half roller 309 move upward as a whole, releasing the fixation on the initial end of the steel coil. Then the initial end of the subsequent steel coil will also be constrained by the leveling roller 806 to achieve leveling. The whole process is automated and can make the wound steel coil fully leveled without dead angles.
