Double-bracing vertical type straightening machine

Abstract

The invention discloses a double-bracing vertical type straightening machine. The double-bracing vertical type straightening machine comprises a drive side rack, a roll collar assembly, an axial adjusting device and a locking device. The double-bracing vertical type straightening machine further comprises an operation side rack and an operation side sliding seat, wherein the operation side sliding seat is fixedly arranged. The lower end of the roll collar assembly is arranged on the drive side rack, the upper end of the roll collar assembly is arranged on the operation side rack, and the operation side rack is arranged on the operation side sliding seat and is matched with the operation side sliding seat along a horizontal line in a sliding mode. The double-bracing vertical type straightening machine further comprises a roller-replacing hydraulic cylinder connected with the operation side rack. According to the double-bracing vertical type straightening machine, the upper end of the roll collar assembly and the lower end of the roll collar assembly are both supported by the racks, a simple-supporting structure is formed to enable the roll collar assembly and the rack to be better in rigidity, the roll collar assembly and the rack are not prone to deforming during a straightening process, the quality of a straightened product can be effectively improved, and internal residual stress of the product can be reduced. When rollers are replaced, the operation side rack can be moved away from the upper end of the roll collar assembly integrally through the roller-replacing hydraulic cylinder, the roller-replacing operation is simple, roller-replacing time is short, and production efficiency and equipment utilization rate can be improved.

Description

technical field [0001] The invention relates to a straightening machine, in particular to a double-support vertical straightening machine. Background technique [0002] After the profile is rolled and formed, it will be bent or twisted due to factors such as external force, temperature change, and internal force. In order to obtain a straight finished product, it must be straightened. For rails, because of its high requirements on cross-section shape and straightness, it is necessary to add a straightening machine with vertical straightening rollers after the straightening machine with horizontal straightening rollers (usually called vertical straightening Machine), and strive to ensure the straightness requirements of the rail. [0003] At present, the vertical straightening machines in use at home and abroad are all cantilever-type structures, which not only have slightly poor rigidity, and the straightening accuracy is not easy to guarantee, but also have defects such as...

Problems solved by technology

[0003] At present, the vertical straightening machines in use at home and abroad are all cantilever-type structures, which not only have slightly poor rigidity, and the straightening accuracy is not easy to guarantee, but also have defects such as differences in the rail height of the straightened rails and excessive residual stress.
