Description

Technical Field

[0001] The invention relates to a coiling machine, in particular to a fully automatic vertical coiling machine for hot-rolled strip steel. Background Art

[0002] During the hot-rolled strip production process, the strip is rolled into shape in the finishing mill, then passed through a laminar cooling roller to the coiler, where it is coiled into coils. The coils are then bundled by a baler and transported to the coil storage area. The coiler, which coils the strip, is the final, critical step in the hot-rolling process. Production practice has shown that the coiler's operating status directly impacts the production capacity of the entire rolling mill, and its performance impacts the final quality and profitability of the finished strip.

Hot-rolled strips vary in width: strips under 600mm are considered narrow strips, while strips over 600mm are considered wide strips.

The telescopic motor 12 is fixedly connected to the stable seat 13 and the limit sleeve 17. The first curling component 3 and the second curling component 4 have the same structure, are arranged opposite to each other, and are connected by a rotating connecting shaft 5. Specifically, the rotating connecting shaft 5 inside the second curling component 4 is provided with a groove body, and the rotating connecting shaft 5 inside the first curling component 3 is provided with a protrusion, and the protrusion and the groove body can be adapted for sliding connection. The adjusting squeeze roller 6 and the arc-shaped regulating frame 7 are elastically and telescopically connected on the spring connecting rod 9 through the adjusting displacement frame 8, and the adjusting squeeze roller 6 is in contact with the hot-rolled strip. The adjusting squeeze roller 6 can be connected to rotate. There are six movable toothed discs 15, which are symmetrically distributed around the second toothed disc 16. While the movable toothed disc 15 revolves on the second toothed disc 16, it can be adjusted to rotate. The upper end of the driving toothed disc 20 is meshed with the first toothed disc 14. The first toothed disc 14 adopts a double-sided toothed structure, and the driving toothed disc 20 drives the movable toothed disc 15 and the second toothed disc 16 to rotate as a whole through the first toothed disc 14. The connecting column 18 is fixedly connected to the limiting sleeve 17. The positioning connecting rod 19 is driven by the motor of the external machine. The second toothed disc 16 inside the second curling component 4 can drive the rotating shaft 5 to rotate by rotating to realize the curling function. At the same time, the telescopic motor 12 can control the telescopic adjustment of the position of the rotating shaft 5, which is convenient for canceling the connection of the hot-rolled strip and facilitating the transmission of the hot-rolled strip.

[0029] like Figure 2 、 Figure 4 、 Figure 5 As shown, the position limiting driving structure 2 includes a connecting column 18 , a positioning connecting guide rod 19 , a driving gear disc 20 , a protection connecting seat 21 , a first nested stretching rod 22 and a second nested stretching rod 23 . One side of the lower end of the connecting column 18 is fixedly connected to a positioning connecting rod 19, and the other side of the lower end of the connecting column 18 is fixedly connected to a protection seat 21. The centers of the positioning connecting rod 19 and the protection seat 21 are rotatably connected to a driving gear disc 20. One end of the driving gear disc 20 close to the center of the protection seat 21 is fixedly connected to the first nested stretching rod 22, and the first nested stretching rod 22 adopts a stretching structure through the second nested stretching rod 23. The connecting column 18, the positioning connecting rod 19, the driving gear disc 20, the protection seat 21, the first nested stretching rod 22 and the second nested stretching rod 23 are combined to drive the load-bearing curling structure 1. The driving gear disc 20 can drive the first gear disc 14 to rotate, and the second nested stretching rod 23 can be telescopically coordinated. When the load-bearing curling structure 1 is adjusted, the limit drive structure 2 can perform adaptive regulation.

[0030] The working principle of embodiment 1 is: when in use, the load-bearing curling structure 1 and the position-limiting driving structure 2 are combined, and the external motor is combined and connected with the position-limiting driving structure 2.

[0031] First, the hot-rolled strip is wound on the rotating connecting shaft 5. At this time, the motor is working, and the motor can drive the driving gear disc 20 to rotate. While the driving gear disc 20 rotates, it can drive the first gear disc 14 to rotate. When the first gear disc 14 rotates, it synchronously drives the movable gear disc 15 to rotate. When the movable gear disc 15 rotates, it can drive the second gear disc 16 to rotate, thereby achieving the driving purpose.

[0032] Afterwards, the rotation of the second gear plate 16 can drive the connecting movable plate 11 to rotate, and the rotation of the connecting movable plate 11 can drive the rotating connecting shaft 5 to rotate when the limiting disc frame 10 rotates, and the limiting disc frame 10 keeps its position fixed, and the rotating connecting shaft 5 rotates on itself. Through the rotation of the rotating connecting shaft 5, the hot-rolled strip is coiled, so that the hot-rolled strip is connected to the rotating connecting shaft 5.

[0033] Afterwards, the drive of the driving gear disc 20 is stopped. At this time, the first gear disc 14, the movable gear disc 15, and the second gear disc 16 do not rotate. At the same time, the telescopic motor 12 works, and the telescopic motor 12 drives the rotating shaft 5, the adjusting squeeze roller 6, the arc-shaped regulating frame 7, the adjusting displacement frame 8, the spring connecting rod 9, the limit disk frame 10, and the guide movable disk 11 to shrink, so that the symmetrically arranged first curling component 3 and the second curling component 4 are disengaged. At the same time, the crane is connected to the steel coil, and the steel coil is moved away from the inside of the load-bearing curling structure 1 and the limit driving structure 2.

[0034] Finally, when the load-bearing curling structure 1 is extended and retracted, the second nested stretching rod 23 can cooperate to perform telescopic adjustment, thereby preventing the limit drive structure 2 from breaking. At the same time, when the hot-rolled strip is curled, the adjustment squeeze roller 6 will come into contact with the hot-rolled strip. The adjustment squeeze roller 6 can be telescopically adjusted on the spring connecting rod 9 through the arc-shaped control frame 7 and the adjustment displacement frame 8, and cooperate with the pressing of the hot-rolled strip to prevent the hot-rolled strip from falling off and complete the work.

[0035] Example 2

[0036] On the basis of Example 1, Figure 6 As shown, the front end of the connecting column 18 is fixedly connected to a protective connecting seat frame 24, the upper end of the protective connecting seat frame 24 is rotatably connected to a connecting combined guide rod 25, and the upper end of the connecting combined guide rod 25 is telescopically connected through a telescopic shaft sleeve frame 26.

[0037] When implementing this embodiment, the user combines the protective connecting frame 24, the connecting combination guide rod 25, and the telescopic shaft sleeve frame 26. The protective connecting frame 24 and the connecting combination guide rod 25 are adaptively arranged. The connecting combination guide rod 25 can rotate around the protective connecting frame 24. At the same time, the telescopic shaft sleeve frame 26 can be stretched and adjusted. When the load-bearing curling structure 1 rotates, the telescopic shaft sleeve frame 26 cooperates to stretch.

[0038] It should be noted that matters not described in detail in this embodiment are well-known technologies in the art.

[0039] The above description is only for the purpose of describing the present invention in detail for the purpose of describing specific embodiments of the present invention. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the scope of protection of the present invention.
