Crawler belt steel rolling type low-temperature correcting device

Abstract

The invention discloses a crawler belt steel rolling type low-temperature correcting device, and belongs to the field of special-shaped steel reshaping. The device comprises a supporting piece, a lower correcting roller mechanism and an upper correcting roller mechanism. The supporting piece is used for providing support. The lower correcting roller mechanism is provided with a lower correcting roller, and the lower correcting roller is rotationally arranged on the supporting piece. The upper correcting roller mechanism is provided with an upper correcting roller, and the upper correcting roller is rotationally arranged on the supporting piece and located above the lower correcting roller. The space defined by the upper correcting roller and the lower correcting roller is matched with theoutline of crawler belt steel in shape and size so that the crawler belt steel located between the upper correcting roller and the lower correcting roller can be corrected. Through the above technicalscheme, it is guaranteed that the size of the crawler belt steel meets the requirement, it is also guaranteed that the steel surface quality and the usage performance of the crawler belt steel are good, and the correcting precision and the correcting efficiency are further improved.

Description

technical field [0001] The invention belongs to the field of plastic shaping of special-shaped steel materials, in particular to a rolling low-temperature straightening device for track steel. Background technique [0002] Due to the large tonnage of large and medium-sized mechanical equipment, the crawler structure is used to replace the wheel structure in the operation mode. With the advancement of science and technology, more and more jobs are replaced by machinery, and the application range of track steel is becoming wider and wider. Track steel as For special-shaped steel, the rolling force received during the rolling process is uneven, and the stress generated during the cooling process is uneven. After passing through, due to the uneven and incomplete stress relief, the track steel is prone to cooling deformation in the rolling direction , affect the use of the next process; currently there is no special track steel low-temperature straightening device, and in the pas...

[0002] Due to the large tonnage of large and medium-sized mechanical equipment, the crawler structure is used to replace the wheel structure in the operation mode. With the advancement of science and technology, more and more jobs are replaced by machinery, and the application range of track steel is becoming wider and wider. Track steel as For special-shaped steel, the rolling force received during the rolling process is uneven, and the stress generated during the cooling process is uneven. After passing through, due to the uneven and incomplete stress relief, the track steel is prone to cooling deformation in the rolling direction , affect the use of the next process; currently there is no special track steel low-temperature straightening device. In the past, only a jack was used for straightening. to correct
