Steel coil pressing device capable of synchronously and transversely moving with coiling machine and pressing method

Abstract

The invention belongs to the technical field of strip steel finishing, and provides a steel coil pressing device capable of synchronously and transversely moving with a coiling machine and a pressing method. The pressing device comprises a base, a swing arm support is hinged to the base through a mandrel, and the far end, away from a coiling block, of the swing arm support is connected with the base through a swing device; and a girder is arranged at the near end, close to the coiling block, of the swing arm support, a cross beam is arranged on the girder through a transverse shifter, a compression roller is arranged on the cross beam, the compression roller swings in the radial direction of the coiling block through the swing device, and the compression roller transversely moves in the axial direction of the coiling block and synchronously along with the coiling block through the transverse shifter. When the strip steel drifts to be separated from a tension roller, after a pressing device is put in and presses the outer ring of a steel coil, the coiling block of the coiling machine and the pressing device can still be kept to synchronously and transversely move, and the edge of the strip steel is always kept to be aligned until coiling is completed, so that the problem of coiling shapes of the last two circles is solved.

Description

technical field [0001] The invention belongs to the technical field of steel strip finishing, and in particular relates to a method and a device for compacting steel coils that can be moved horizontally synchronously with a coiler. Background technique [0002] During the tail-flicking stage of the skin-passing unit until the tail of the strip leaves the tension roller, the hold-down device is automatically put into place to press the outer ring of the steel coil to avoid unwinding. The compression device used in the skin-passing unit currently under construction and operation can only swing along the diameter direction of the steel coil, and cannot move laterally with the reel of the coiler synchronously. After the compression roller is put in, the EPC will stop inputting and the reel will stop moving laterally. . It will directly lead to an uncontrollable state of displacement in the strip width direction from the tension roller area to the coiler reel, which is 6-10 mete...

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a method and device for compacting steel coils that can be traversed synchronously with the coiler, aiming at effectively solving the tower shape problem of the last one or two circles of steel coils when the skinning unit is coiled. In order to improve the quality of strip steel coil and reduce the abnormal tower shape processing process
