Description

Technical Field

[0001] The utility model relates to the field of sheet metal processing, in particular to a hot-rolled coil sheet leveler. Background Art

[0002] A leveler is a machine that performs a series of processing operations such as uncoiling, leveling, and shearing on coiled metal sheets. It usually includes an uncoiling device, a leveling device, and a shearing device. The uncoiling device drives the coiled sheet to rotate, and cooperates with a guiding structure to guide the end of the sheet into the leveling device for leveling. The leveled sheet is cut into sheets of a certain length by the shearing device.

[0003] In the existing uncoiling device, usually after inserting a roller shaft into the hole in the middle of the coiled sheet, the roller shaft is driven to rotate by a motor to drive the coiled sheet to rotate. Due to the large weight of the coiled sheet, the friction between it and the roller shaft is also relatively large, which makes the roller shaft prone to wear during use. In addition, since the roller shaft is mostly of a fixed structure, this leads to a phenomenon of slipping easily between the roller shaft and the coiled sheet, which is not conducive to the uncoiling operation.

[0027] As Figures 1-7As shown in the figure, a hot-rolled coil sheet leveler is disclosed in this embodiment, which includes an uncoiling device 2, a leveling device 3, and a shearing device 4 arranged in sequence on the ground 1. It is characterized in that: the uncoiling device 2 includes a supporting and feeding mechanism 21 movably arranged in a groove 101 on the ground 1. On both sides of the supporting and feeding mechanism 21, there are movably arranged corresponding rotary driving mechanisms 22. The rotary driving mechanisms 22 are arranged on the ground 1 through a base 23; the rotary driving mechanism 22 includes a mounting plate 221 slidably clamped with the base 23. On one side of the mounting plate 221, there is a linear driving component one 222 connected to the base 23; a driving motor 223 is fixedly installed on the mounting plate 221. A turntable 224 is coaxially fixedly connected to the output shaft of the driving motor 223. A hollow roller shaft 225 is coaxially fixedly connected to the turntable 224. A plurality of through holes are circumferentially arranged on the side wall of the hollow roller shaft 225. A pressing plate 226 is movably arranged in the through holes. An elastic telescopic component 227 is connected to the pressing plate 226. The elastic telescopic component 227 is arranged in the hollow roller shaft 225; an adjusting component 228 is connected to the inner wall of the hollow roller shaft 225, and the adjusting component 228 drives the elastic telescopic component 227 to perform radial expansion and contraction.

[0028] In this embodiment, the supporting and feeding mechanism 21 is used to support the coiled sheet material and transport it between the two rotary driving mechanisms 22; the base 23 is fixed on the ground 1.

The fixed end of the linear driving component one 222 is fixed on the base 23, and the action end of the linear driving component one 222 is fixedly connected to the side wall of the mounting plate 221.

[0029] The working process of the above technical solution is as follows: Place the coiled sheet material on the supporting and feeding mechanism 21, and transport it to between the two rotary driving mechanisms 22 through the supporting and feeding mechanism 21; drive the mounting plate 221 to move towards the direction close to the coiled sheet material through the linear driving component one 222 until the hollow roller shaft 225 is inserted into the hole in the middle of the coiled sheet material; then drive the elastic telescopic component 227 to perform radial elongation through the adjusting component 228 until the pressing plate 226 extends out of the through hole and tightly presses against the hole wall of the coiled sheet material; then drive the turntable 224 and the hollow roller shaft 225 to rotate through the driving motor 223, and the coiled sheet material can be driven to rotate.
