A horizontal loop guide roller device

Abstract

The invention discloses a horizontal loop guide roller device which comprises a loop table, a guide roller with a table and a lining arranged in the guide roller with the table. The guide roller device further comprises an eccentric shaft, a bearing set and locking devices used for locking the two ends of the bearing set. The eccentric shaft comprises a first shaft part and a second shaft part arranged in the lining. The guide roller with the table is connected with the loop table through the first shaft part. The bearing set is arranged between the second shaft part and the lining and bears axial loads in the axial directions of the two ends of the bearing set by means of the series-connection arrangement and back-to-back arrangement between bearings. According to the guide roller device, the loop bearings and clamping springs can be prevented from being damaged, the situation that because the guide roller plays, a rolled piece is scratched by an outlet guide groove is avoided, the steel piling accidents caused by falling-off of the guide roller are eradicated, abrasion to the loop outlet guide groove and an inlet guide of a rolling mill is reduced, the product quality is improved, and rolling cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal rolling equipment, and in particular relates to a horizontal loop guide roller device. Background technique [0002] Between the high-speed wire roughing mill and the pre-finishing mill, in order to realize tension-free rolling, a horizontal looper device is installed to adjust the speed of the upstream rolling mill, so as to ensure that the volume flow per second of the front and rear racks is equal. The exit guide roller of the existing horizontal looper device is composed of a guide roller with a platform and two flat rollers. The roller surface of the guide roller with a platform has steps to prevent the upward movement of the rolled piece, but its internal structure is the same as that of the flat roller. High-speed wire The rolling piece moves in an arc shape after the horizontal looper is set up. Under the action of the upward force of the rolling piece, the bearing and the retaining spring o...

Problems solved by technology

The exit guide roller of the existing horizontal looper device is composed of a guide roller with a platform and two flat rollers. The roller surface of the guide roller with a platform has steps to prevent the upward movement of the rolled piece, but its internal structure is the same as that of the flat roller. High-speed wire The rolling piece moves in an arc shape after the horizontal looper is set up. Under the action of the upward force of the rolling piece, the bearing and the retaining spring of the belt table guide roller often suffer damage. Scratches, affecting product quality, and even lead rollers fall off and cause stacking accidents

For the production of high value-added products such as annealing-free, simplified annealing and non-quenched and tempered steel with high cold heading performance, the shape of the bar is very demanding during the rolling process, and a small scratch of 0.05mm on the finished product may cause cold heading of the product If the performance is unqualified, if there is a scratch greater than 0.2mm on the strip in the middle rolling area, it is reflected in the finished product as intermittent folding, which is not easy to find with the naked eye, but the rolled product may be a waste product, which can easily cause batch quality accidents
