Embodiment Construction
[0015] Such as figure 1 Shown, the present invention comprises left bearing 1, opposing clamping device base 2, opposing chuck height adjustment device 3, hydraulic cylinder 4, opposing chucking 5, right bearing 6, left suspension beam 7, right suspension beam 8. When the pallet transports the coil to the tower-shaped correction position, the hydraulic cylinder pushes the chuck to move to the middle to achieve clamping. When the diameter of the coil changes, the height of the chuck is adjusted through the height adjustment device of the chuck. When the coil deviates from the center line of the tray, the pressure difference is controlled to make the opposite chuck exert pressure on the coil at the same time.
[0016] The right support 6 and the right cantilever beam 8 enable the right clamping device to straddle the empty pallet, so that the empty pallet can be returned when the coil adopts the double row pallet transport mode; the clamping disc 5 is pushed by the hydraulic cy...

The invention discloses a coil butt clamp device, and belongs to the technical field of correction of telescopes of hot or cold rolled coils. The coil butt clamp device consists of a left support, a right support, a left cantilever beam, a right cantilever beam, a butt clamp device base, a hydraulic cylinder, butt clamp chucks, and a butt clamp chuck height adjusting device; the right support andthe right cantilever make the butt clamp device span a no-load tray; the hydraulic cylinder pushes the butt clamp chucks to realize the correction of the telescopes of the coils; and the height of the butt clamp chucks is adjusted by the butt clamp chuck height adjusting device. The right support and the right cantilever beam make the butt clamp device on the right side span the no-load tray, so that the butt clamp device can realize the correction of the telescopes in a double tray transportation system. The position adjustment of the butt clamp chuck in the height direction is realized by driving worm and gear or other similar height adjusting devices through a motor. That the butt clamp chucks on two sides simultaneously press the coils is realized through hydraulic control, and the pressure can be adjusted; and when the coils are deviated with the center line of the tray, the simultaneous clamping is realized through pressure difference control. The coil butt clamp device is applied to the correction of the telescopes of the coils coiled by rolled strip steel and nonferrous metal strips, and particularly improves the telescopes of the hot rolled strips.
Description
technical field [0001] The invention belongs to the technical field of tower shape correction of hot-rolled or cold-rolled coils, and particularly provides a coil clamping device. Technical field of tower corrections for rolled coils. Background technique [0002] The tower-shaped correction device has been used in the hot-rolled strip steel production line, but because the pressure cannot be adjusted, the alignment effect is not good, and its height position adjustment method is manual, which cannot realize electrical automation. When the coil deviates from the center line of the pallet, the chucks on both sides cannot apply pressure to the coil at the same time, resulting in a large lateral force. Especially when adopting the double-row pallet transportation method, the existing tower correction device cannot be used because it blocks the return of empty pallets. Contents of the invention [0003] The object of the present invention is to provide a coil clamping device...
