Description

Technical Field

[0001] This utility model relates to a steel coil positioning mechanism for a steel rolling uncoiling machine, belonging to the field of steel rolling processing technology in the metallurgical industry. Background Technology

[0002] During the steel rolling process, steel coils need to be uncoiled. Since steel coils are large in volume, an uncoiling machine is required for uncoiling.

[0003] After the steel coil is placed into the uncoiling machine, a support platform is used to provide some support for the uncoiling machine. However, most existing uncoiling machines only have a supporting function. At the same time, since the inner wall of the steel coil and the positioning mechanism on the uncoiling machine that fixes the steel coil are mostly smooth, slippage is likely to occur during the uncoiling process, which reduces the uncoiling stability of the uncoiling machine and easily affects the uncoiling efficiency. Therefore, an uncoiling machine for steel rolling processing is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a steel coil positioning mechanism for a steel rolling mill uncoiling machine. During the uncoiling process, the mechanism can clamp, squeeze, and position the steel coil, increase the friction of the steel coil on the uncoiling machine, prevent the steel coil from slipping during the uncoiling process, and solve the problems existing in the background art.

[0005] The technical solution of this utility model is: A steel coil positioning mechanism for a steel rolling mill uncoiling machine includes an uncoiling machine base, a guide rail, a release assembly, and a pressing assembly; Two guide rails are provided on one side of the unwinding machine base; The release assembly includes a movable seat, a threaded block, a drive motor, a threaded column, a lifting seat, a drive roller, and a driven roller. The threaded block is threadedly connected to the threaded column, which is located between two guide rails. The drive motor is drivenly connected to the threaded column. The movable seat is fixed to the threaded block and slidably connected to the two guide rails. The lifting seat is located on the movable seat and is equipped with a drive roller and a driven roller (58). The drive roller and the driven roller are located below the steel coil of the unwinding machine and cooperate with the steel coil of the unwinding machine. The pressing assembly includes a fixed column, a groove, a ball screw, a threaded rod, a threaded sleeve, a fixed plate, a mounting frame, and a positioning roller. The fixed column is provided with a groove that cooperates with the ball screw. The threaded rod is connected to the ball screw. The fixed plate is connected to the threaded rod through the threaded sleeve. The mounting frame is fixed on the fixed plate. The positioning roller (610) is rotatably connected to the mounting frame. The positioning roller is located on the steel coil of the unwinding machine and cooperates with the steel coil of the unwinding machine.

[0006] The ball screw in the pressing assembly is equipped with a limiting rod, which is fixed to the lifting seat.

[0007] The lifting seat is provided with a groove that cooperates with the limiting rod, and the limiting rod is set in the groove of the lifting seat.

[0008] The limiting rod is connected to the ball screw via a lead screw sleeve.

[0009] The drive roller in the release assembly is driven by a servo motor, and the driven roller and the drive roller are connected together by a toothed sprocket transmission.

[0010] An electric telescopic rod is provided between the lifting seat and the moving seat in the release assembly.

[0011] The guide rail is provided with a sliding groove that cooperates with the movable seat.

[0012] The beneficial effects of this utility model are: (1) The lifting seat moves upward under the action of the electric telescopic rod, which supports the steel coil. During the upward movement of the lifting seat, the ball screw rotates under the action of the screw seat, thereby driving the threaded rod to rotate. Under the action of the threaded sleeve, the fixing plate and the mounting frame drive the positioning roller to move downward. With the cooperation of the positioning roller and the lifting seat, the steel coil is clamped and squeezed, which ensures the friction of the steel coil on the uncoiling machine and avoids the steel coil from slipping during the uncoiling process, further ensuring the stability of the uncoiling machine during the uncoiling process.

[0013] (2) The movable seat can drive the lifting seat to move. Under the action of the electric telescopic rod, the lifting seat can be adjusted in real time according to the size of the rolled steel coil, ensuring the support of the lifting seat for the rolled steel coil, reducing the pressure of the rolled steel coil on the uncoiling machine, thereby reducing the wear of the rolled steel coil on the uncoiling machine and improving the service life of the uncoiling machine. At the same time, during the uncoiling process, the drive roller and the driven roller maintain the rolled steel coil at a stable and uniform speed under the action of the friction strip, ensuring the stability of the uncoiling machine and ensuring the uncoiling efficiency of the uncoiling machine.

[0020] Working principle: During the unwinding process of the steel coil, the drive motor 53 drives the threaded column 54 to rotate. Under the action of the thread, the threaded block 52 moves towards the machine base 1 on the threaded column 54, thereby driving the movable seat 51 to move within the slide groove 4 via the limit bar 59. The movable seat 51 drives the lifting seat 55 to move below the steel coil via the electric telescopic rod 510. Then, the electric telescopic rod 510 drives the lifting seat 55 to move upward. After the outer surfaces of the drive roller 57 and the driven roller 58 are in contact with the outer surface of the steel coil, the upward movement of the lifting seat 55 stops. As the lifting seat 55 moves upward, it simultaneously moves the limiting rod 65 upward. At this time, the limiting rod 65 causes the lead screw sleeve 64 to move upward on the outer surface of the ball screw 63. As the lead screw sleeve 64 moves, the ball screw 63 drives the threaded rod 66 to rotate within the groove 62. Under the action of the threaded sleeve 67, the fixing plate 68 moves downward towards the fixing column, thereby driving the positioning roller 610 downward through the mounting bracket 69. At this time, the positioning roller 610 and the drive roller 57 will compress the steel coil, ensuring the stability of the uncoiling machine. Simultaneously, during the uncoiling process, the drive motor 53 drives the drive roller 57 to rotate through the rotating rod 511. Under the action of the toothed sprocket 512 and the toothed chain, the rotating rod 511 drives another rotating rod 511 to rotate the driven roller 58. Under the action of the drive roller 57 and the driven roller 58, the stability of the uncoiling machine is further ensured.
