Description

A cold-rolled steel coil unwinding device Technical Field

[0001] This application relates to the field of cold-rolled steel coil uncoiling technology, and more particularly to a cold-rolled steel coil uncoiling device. Background Technology

[0002] Cold rolling uses hot-rolled steel coils as raw materials. After pickling to remove oxide scale, the coils are continuously cold-rolled to produce hard-rolled coils. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coils increase while their toughness and plasticity decrease. As a result, their stamping performance deteriorates, and they can only be used for parts with simple deformation. When uncoiling cold-rolled steel coils, they are usually placed on a rotating shaft, and then the shaft is rotated to uncoil the steel coil.

[0003] However, while existing uncoiling devices can adjust and position cold-rolled steel coils of different inner diameters, their adjustment and positioning accuracy on the sides of the coils is not high. This causes the coils to slip left and right on the uncoiling rollers due to centrifugal force during rotation, which affects the accuracy of cold-rolled steel coil conveying. Furthermore, the adjustment and positioning effect on coils of different widths is not high, reducing the flexibility of the uncoiling device in placing the coils. Summary of the Invention

[0004] This application provides a cold-rolled steel coil unwinding device to solve the problem mentioned in the background art that when adjusting and placing cold-rolled steel coils with different inner diameters, the adjustment and positioning accuracy of the steel coil side is not high, which causes the steel coil to slip left and right on the unwinding roller due to centrifugal force when rotating.

[0005] This application provides a cold-rolled steel coil uncoiling device, including a cold rolling mill body. An uncoiling motor is fixedly connected to the outer wall of the cold rolling mill body. A connecting block is fixedly connected to the output end of the uncoiling motor. A connecting cylinder is fixedly connected to one end of the connecting block. A servo motor is fixedly connected to the outer wall of the connecting cylinder. A threaded rod rotatably connected to the inner wall of the connecting cylinder is fixedly connected to the output end of the servo motor. A threaded slider slidably connected to the inner wall of the connecting cylinder is threadedly connected to the outer wall of the threaded rod. A rotating rod is rotatably connected to the outer wall of the threaded slider. A telescopic rod slidably connected to the outer wall of the connecting cylinder is rotatably connected to one end of the rotating rod. A positioning post is fixedly connected to one end of the positioning post. A telescopic post is telescopically connected to one end of the telescopic post. An adjusting post is threadedly connected to the inner wall of the telescopic post. An outer spiral is provided on the outer wall of the adjusting post. An inner spiral is provided at the connection between the inner wall of the telescopic post and the outer spiral. A baffle is fixedly connected to one end of the adjusting post. The main body of the steel coil is attached to the outer wall of the positioning post.

[0006] Preferably, the threaded slider forms a sliding structure between the threaded rod and the connecting cylinder, and the inner wall of the connecting cylinder is fixedly connected to the connecting column and the threaded slider for sliding connection.

[0007] Preferably, the telescopic rod forms a sliding structure with the connecting cylinder through a threaded slider and a rotating rod. The telescopic rod is provided in four sets, and the positions of the four sets of telescopic rods are equidistantly distributed about the rotation center of the connecting cylinder.

[0008] Preferably, the outer wall of the positioning post is cylindrical, and the positioning post and the telescopic post are connected by threads.

[0009] Preferably, the adjusting column forms a telescopic structure with the telescopic column through an outer spiral and an inner spiral.

[0010] Preferably, the outer wall contour of the connection between the adjusting column and the baffle is L-shaped.

[0011] Preferably, four sets of baffles are provided, and the positions of the four sets of baffles are equidistant from the rotation center of the connecting cylinder.

[0012] Beneficial effects:

[0013] While existing uncoiling devices can adjust and position cold-rolled steel coils of different inner diameters, their adjustment and positioning accuracy on the sides of the coils is not high. This causes the coils to slip left and right on the uncoiling rollers due to centrifugal force during rotation, which affects the accuracy of cold-rolled steel coil conveying. Furthermore, the uncoiling device is not effective in adjusting and positioning coils of different widths, reducing its flexibility in placing the coils.

[0014] In use, the material roll body is first fitted onto the outer wall of the connecting cylinder, and the servo motor is turned on. The rotation of the threaded rod drives the threaded slider to slide along the inner wall of the connecting cylinder. The sliding of the threaded slider, through the rotation of the rotating rod, drives the positioning column fixedly connected to the telescopic rod to perform telescopic movement, which supports the inner wall of the material roll body. After the material roll is positioned, the adjusting column is rotated. Through the threaded connection between the outer and inner spirals, the baffle rotates synchronously, so that the baffle positions the side wall of the material roll, thereby improving the stability of the placement and installation of material rolls with different inner diameters.

[0030] This utility model provides a cold-rolled steel coil uncoiling device as shown in Figures 1-5, including a cold rolling mill body 1. An uncoiling motor 16 is fixedly connected to the outer wall of the cold rolling mill body 1. A connecting block 2 is fixedly connected to the output end of the uncoiling motor 16. A connecting cylinder 3 is fixedly connected to one end of the connecting block 2. A servo motor 4 is fixedly connected to the outer wall of the connecting cylinder 3. A threaded rod 5, rotatably connected to the inner wall of the connecting cylinder 3, is fixedly connected to the output end of the servo motor 4. A threaded slider 6, slidably connected to the inner wall of the connecting cylinder 3, is threadedly connected to the outer wall of the threaded rod 5. A rotating rod 7 is rotatably connected to the outer wall of the connecting cylinder 3. One end of the rotating rod 7 is rotatably connected to a telescopic rod 8 that is slidably connected to the outer wall of the connecting cylinder 3. One end of the telescopic rod 8 is fixedly connected to a positioning post 9. One end of the positioning post 9 is telescopically connected to a telescopic post 10. An adjusting post 11 is threadedly connected to the inner wall of the telescopic post 10. An outer spiral 12 is provided on the outer wall of the adjusting post 11. An inner spiral 13 is provided at the connection between the inner wall of the telescopic post 10 and the outer spiral 12. A baffle 14 is fixedly connected to one end of the adjusting post 11. The material roll body 15 is attached to the outer wall of the positioning post 9.

[0031] The threaded slider 6 forms a sliding structure with the threaded rod 5 and the connecting cylinder 3, and the inner wall of the connecting cylinder 3 is fixedly connected to the connecting column and the threaded slider 6 for sliding connection.

[0032] It facilitates the rotation of the threaded rod 5, causing the threaded slider 6 to slide along the inner wall of the connecting cylinder 3, thus enabling the rotating rod 7 to rotate easily.

[0033] The telescopic rod 8 forms a sliding structure with the connecting cylinder 3 through the threaded slider 6 and the rotating rod 7. There are four sets of telescopic rods 8, and the positions of the four sets of telescopic rods 8 are equidistant from the rotation center of the connecting cylinder 3.

[0034] The sliding of the threaded slider 6 is facilitated by the connection of the rotating rod 7, which drives the telescopic rod 8 to extend and retract along the outer wall of the connecting cylinder 3, thereby driving the positioning column 9 to extend and retract synchronously.

[0035] The outer wall of the positioning post 9 is cylindrical, and the positioning post 9 and the telescopic post 10 are connected by threads.

[0036] The cylindrical shape of the outer wall of the positioning column 9 facilitates the adjustment and placement of steel coils with different inner diameters.

[0037] The adjusting column 11 forms a telescopic structure with the telescopic column 10 through the outer spiral 12 and the inner spiral 13.

[0038] It is beneficial to drive the adjusting column 11 to move along the inner wall of the telescopic column 10 through the threaded connection between the outer spiral 12 and the inner spiral 13, so as to facilitate the adjustment of the position of the baffle 14.

[0039] The outer wall contour of the connection between the adjusting column 11 and the baffle 14 is L-shaped.

[0040] The L-shaped setting of the outer wall of the connection between the adjusting column 11 and the baffle 14 facilitates convenient fitting and positioning of the material roll sidewall.

[0041] The baffle 14 is provided in four sets, and the positions of the four sets of baffle 14 are equidistant from the rotation center of the connecting cylinder 3.

[0042] By setting four sets of baffles 14 that are equidistant from the rotation center of the connecting cylinder 3, the stability of placing and using material rolls of different sizes can be improved.

[0043] Working principle: When using this cold-rolled steel coil unwinding device, the main body 15 of the coil is first fitted onto the outer wall of the connecting cylinder 3. The servo motor 4 is turned on, and the rotation of the threaded rod 5 drives the threaded slider 6 to slide along the inner wall of the connecting cylinder 3. The sliding of the threaded slider 6 drives the rotation of the rotating rod 7, which drives the positioning column 9, which is fixedly connected to the telescopic rod 8, to extend and retract, thus supporting the inner wall of the main body 15 of the coil. After the coil is positioned, the adjusting column 11 is rotated, and the threaded connection between the outer spiral 12 and the inner spiral 13 drives the baffle 14 to rotate synchronously, so that the baffle 14 positions the side wall of the coil, thereby improving the stability of the placement and installation of coils with different inner diameters.
