Problems solved by technology

[0006] In order to solve the existing method of thermal adjustment on the small longitudinal beam adjacent to the warping deformation end of the circular tube beam, only rely on the local cooling shrinkage deformation of the small longitudinal beam to realize the correction of the warping deformation at the end of the circular tube beam , the arm of force produced by thermal adjustment shrinkage deformation is relatively short, resulting in the technical problem that the maximum vertical adjustment deformation that can be obtained by this method still cannot achieve the effect of completely correcting the warping deformation of the circular tube beam. The present invention provides A method of using a correction device for warping and deformation of crossbeams in a well-shaped frame

Abstract

The invention discloses a correcting device for well-shaped framework cross beam buckling deformation and a using method thereof, and belongs to the field of rail vehicle bogie manufacturing devices and methods. The correcting device comprises a base, four vertical pressing mechanisms, four cross beam supporting seats, two cross beam spacing limiting baffles and a jack. According to the correctingdevice, the upward buckling deformation amount which is not easy to obtain and correct originally is converted into a known amount which is easy to obtain and is warped downwards, when a traditionalflame heating adjustment and repair mode is utilized, the specific numerical range of the given additional deformation compensation amount is preset for the deformation resilience amount of a workpiece during thermal shrinkage deformation, so that the workpiece is closer to an ideal drawing theoretical size value after being naturally cooled, and then the optimal buckling deformation amount correction effect is achieved.

Description
