Description

Spindle bracket of reciprocating transverse cogging mill Technical Field The utility model belongs to the technical field of steel rolling equipment structures, and particularly relates to a spindle bracket of a reciprocating transverse cogging mill. Background The cogging mill is a device for rolling raw materials (such as steel ingot and continuous casting billet) into billets meeting the subsequent processing requirements in the steel production process, and belongs to core equipment of metallurgical rolling technology. The reciprocating transverse cogging mill is a cogging mill with special structure, and its core features that the roller can make reciprocating motion along transverse direction (perpendicular to the conveying direction of blank) while rotating, so that the blank is compressed and deformed in multiple directions during rolling process, and the problem of uneven deformation of blank edge in traditional rolling mill is solved, especially suitable for cogging of large-section or complex-shape blank. The transmission connecting shaft is a key component for transmitting power in a cogging mill, one end of the transmission connecting shaft is connected with a motor or a speed reducer through a coupler and the like, the other end of the transmission connecting shaft is connected with a roller through a flat head sleeve to transmit power to the roller to drive the roller to rotate for rolling, and when the flat head sleeve of the transmission connecting shaft and the flat head on the roller are dislocated, separated or in poor contact, the power transmission is interrupted or unstable, which is called a flat head sleeve joint phenomenon. Because the roller of the reciprocating transverse moving type cogging mill also makes reciprocating motion along the transverse direction while rotating, and the existing spindle bracket is generally fixedly arranged at the position, close to the flat head sleeve of the roller, of the transmission side of the cogging mill, the existing spindle bracket cannot be correspondingly adjusted according to the timely position of the transmission spindle, the function of stably supporting the transmission spindle cannot be realized, and meanwhile, the phenomenon of flat head sleeve joint is easy to occur. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, an object of the present utility model is to provide a spindle bracket of a reciprocating-type cogging mill, which is used for solving the problem that when a roller of the reciprocating-type cogging mill does a reciprocating motion in a transverse direction while rotating, the spindle bracket in the prior art cannot be adjusted correspondingly according to a timely position of a transmission spindle, and thus cannot realize a function of stably supporting the transmission spindle, and at the same time, a flat head sleeve joint is easy to occur.
