Vertical roller axial adjustment device

Abstract

The invention discloses a vertical roller axial adjustment device, which is designed aiming at the disadvantage in the prior art that a vertical roller cannot be subjected to axial adjustment. The vertical roller axial adjustment device comprises two racks and a vertical roller unit connected onto the two racks, wherein the vertical roller unit comprises a vertical roller framework for fixing the vertical roller; the vertical roller is fixed between the two racks by the vertical roller framework; adjusting pieces are arranged above and below the vertical roller framework; each adjusting piece comprises at least one bolt seat and an adjusting bolt which is in thread connection with the bolt seat; the bolt seats are fixedly connected with the racks; the adjusting bolts are in contact with the vertical roller framework; the vertical roller axial adjustment device further comprises a guiding unit which is used for limiting the vertical roller unit to move up and down along a straight line. By virtue of the vertical roller axial adjustment device, the vertical roller can be subjected to the axial adjustment and the machining and mounting precision of the vertical roller of a rolling mill are reduced to the greatest extent; the cost and the time are saved; the precision of a rolled product is improved and the consumption of the roller is reduced.

Description

technical field [0001] The invention relates to the technical field of steel rolling production, in particular to an axial adjustment device for vertical rolls. Background technique [0002] In the steel rolling production line, the universal rolling mill plays a very important role. The processing and assembly accuracy of the vertical roll of the universal rolling mill directly affects the quality of the rolled steel products. [0003] In the traditional technology, the vertical roll of the universal rolling mill cannot be adjusted axially. In order to ensure the rolling accuracy of the rolling mill, the manufacturing and installation requirements of the vertical roll are very high, which greatly increases the processing cost and the assembly time of the rolling mill. When the universal rolling mill rolls asymmetric section steel (such as channel steel), the turning volume of the upper and lower rolls of the rolling mill is very large, and the vertical roll turning volume o...

Problems solved by technology

[0003] In the traditional technology, the vertical roll of the universal rolling mill cannot be adjusted axially. In order to ensure the rolling accuracy of the rolling mill, the manufacturing and installation requirements of the vertical roll are very high, which greatly increases the processing cost and the assembly time of the rolling mill.

When the universal rolling mill rolls asymmetric section steel (such as channel steel), the turning volume of the upper and lower rolls of the rolling mill is very large, and the vertical roll turning volume of the upper and lower rolls is also very large, which greatly increases the consumption of rolling rolls.
