Energy-saving type rough rolling front pinch roller device

Abstract

The invention discloses an energy-saving type rough rolling front pinch roller device which comprises a pinching device, a transmission device and a clutch device, wherein the pinching device comprises a vertical column, a lower roller seat, a lower roller assembly, an upper roller assembly, an upper roller seat, a lifting cylinder, an inlet guide slot and a lower roller seat adjustment screw rod; the lower roller assembly is mounted in the lower roller seat and is fixed on the vertical column; the upper roller assembly is mounted in the upper roller seat and is fixed on the vertical column; the lifting cylinder is connected with the upper roller seat; the lower roller seat adjustment screw rod is arranged below the lower roller seat; the transmission device comprises a motor, a coupler, a speed reducing box and a transmission shaft; the clutch device comprises a cylinder seat, a telescopic cylinder, a shifting fork, a shifting fork support and a tooth type clutch body; the shifting fork support moving along with the lower roller seat is fixed on the side surface of the lower roller seat; the telescopic cylinder is connected with the clutch body through the shifting fork; the clutch body is connected with a transmission shaft flange. The energy-saving type rough rolling front pinch roller device saves energy consumption, and abrasion to the surface of a roller is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel rolling production, and relates to pinch roll equipment before rough rolling, in particular to an energy-saving pinch roll device before rough rolling that reduces power consumption by changing the transmission connection mode. Background technique [0002] In the prior art of rolling mills, a pinch roll is installed before the roughing mill unit, which is used to pinch the steel billet on the roller table to the 1# roughing mill and make it bite smoothly. The pinch roll before rough rolling usually has upper and lower rolls, the lower roll is generally a driving roll, and the upper roll is a driven roll. In order to ensure that the steel billet can bite into the rolling mill smoothly, the speed of the pinch roll before rough rolling is set to have a certain amount ahead of the speed of the 1# rolling mill. When the steel billet arrives at the pinch roll before rough rolling, the operator issue...

Problems solved by technology

[0004] In order to overcome the excessive waste of power consumption due to the fact that the motor of the pinch roll before rough rolling has to keep running in normal production in the prior art, the purpose of the present invention is to provide an energy-saving pinch roll device before rough rolling, which adopts The pinch roller device can save energy consumption, and at the same time avoid the slipping phenomenon caused by the difference between the tangential speed of the roller surface and the billet speed in the assembly of the lower roller, and correspondingly reduce the wear on the roller surface
