Guide and guard device

Abstract

The invention discloses a guide and guard device. The guide and guard device comprises a guide and guard body; a rotary shaft is fixed in the center at the lower end of the guide and guard body; a bearing is arranged on the rotary shaft; the guide and guard body is provided with a water channel; one end of the water channel is provided with a water inlet; a water outlet which is formed in the other end is arranged at the lower end of the guide and guard body. According to the guide and guard device, the guide and guard body is provided with the water channel and accordingly the assembling process of simplifying guide and guard is achieved and maintenance is convenient; two water injection nozzles on a water pipe and the guide and guard body are communicated and accordingly uniform cooling and temperature reduction of a rolling wheel can be achieved and jamming due to the fact that the temperature of the rolling wheel is excessively high is avoided.

Description

[0001] technical field [0002] The invention relates to the technical field of rolling mill material guidance, in particular to a guide device. Background technique [0003] 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-finishing an...

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
