Abstract

The invention discloses a guide and guard guide roller openness adjusting device which comprises a guide roller, a worm gear and a worm rod. The guide roller comprises a guide roller body and a guide roller shaft, wherein the guide roller body is arranged outside the guide roller shaft in a sleeving mode and is driven by the guide roller shaft to move peripherally, the guide roller shaft is an eccentric shaft, a connecting shaft is arranged at the end of the guide roller shaft, and the worm gear is movably connected with the connecting shaft arranged at the end of the guide roller shaft. A movable connection method is that a groove matched with the connecting shaft is formed in the worm gear, the connecting shaft is embedded into the groove to enable the guide roller shaft to move along with the worm gear, the worm rod is in pivot connection with the outer part of the worm gear, and the worm gear can move along with the worm rod. In addition, a gasket is further arranged on the worm gear, and an opening with the consistent shape and size as those of the groove is formed in the gasket; thus, the contact area between the connecting shaft at the end of the guide roller shaft and the worm gear is enlarged, the stress can be dispersed, impact force to a rolled piece is reduced, and the openness of the guide roller can keep unchanged.

Description

technical field

[0001] The invention relates to the technical field of steel rolling, in particular to a device for adjusting the opening degree of guide rollers. Background technique

[0002] The guide is a device installed before and after the roll pass to help the rolled piece enter and exit the roll pass accurately and stably according to the predetermined direction and state during the section steel rolling process. At present, the guide with the world's advanced level has SMS Guides, Morgan guides, Ashlow guides, Danieli guides and FRS guides, etc., all kinds of guides have their own characteristics, but the overall goal is to ensure the quality of wire products.

[0003] Among them, the adjustment of the opening degree of the FRS type guide and guide roller is realized through the worm gear mechanism. Movement, so as to realize the adjustment of the opening degree of the guide roller. The torque transmission between the worm wheel and the guide roller shaft is reali...
