Rolling mill guide and guard device

Abstract

The invention discloses a rolling mill guide and guard device. The rolling mill guide and guard device comprises a guide and guard body, and a base; a spindle is fixed in the center at the lower end of the guide and guard body; the spindle is provided with a bearing; the bearing is fixed on a slide block; the base is provided with a sliding chute matching with the slide block; the guide and guard body is provided with a water passage; one end of the water passage is provided with a water inlet port; the other end thereof is provided with a water outlet port at the lower end of the guide and guard body. The guide and guard body is provided with the water passage, and the water passage is communicated with two water spraying ports, thereby rollers can be uniformly cooled, thus preventing the rollers from being jammed due to the excessive temperature; meanwhile, the guide and guard body is installed on the sliding chute, thereby providing convenience for the linear motion as well as rotating.

Description

technical field [0001] The invention relates to the technical field of rolling mill material guidance, in particular to a rolling mill guide device. Background technique [0002] In rolling mill technology for rolling steel, guides play an important role in the metal forming process. The guides are installed at the entrance and exit of the rolling mill to assist the rolled piece to enter and exit the pass accurately and stably according to the established direction and state, reduce rolling failures, ensure the safety of people and equipment, and improve the working conditions of the rolled piece. At present, with the continuous development of industry and urban construction, the demand for steel is also increasing. In the prior art, a steel rolling device is usually used to produce steel products. The steel rolling device usually includes: a rough rolling mill, a pre-finishing mill, a finishing mill and a reducing and sizing mill arranged in sequence, and the pre-finishin...

AI Technical Summary

Problems solved by technology

It can be seen from the above that during the working process of the guide and guard, the external nozzles are used to spray water to cool down, and the cooling of the rollers is not uniform.

Therefore, the guides in the prior art are prone to overheating and jamming due to uneven cooling, resulting in low reliability of the rolling device; the water inlet and the oil inlet provided on the rolling guides are usually threaded structures, which are connected by threads The water pipe and the oil pipe are connected by means of this connection method, which makes the assembly of the guide and guard cumbersome and inconvenient for maintenance
