Application method of correcting device for warpage deformation of well-shaped frame beams

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

technical field [0001] The invention belongs to the field of rail vehicle bogie manufacturing devices and methods, and in particular relates to a method for using a correction device for warping and deformation of crossbeams of a well-shaped frame. Background technique [0002] The well-shaped frame beam of a certain type of rail vehicle is composed of Figure 1 to Figure 3 As shown, the beam composition includes a first round tube beam 1, a second round tube beam 2, a first small longitudinal beam 3, a second small longitudinal beam 4 and a plurality of auxiliary weldments 10, the first round tube beam 1 and the second The two circular tube beams 2 are parallel to each other, the first small longitudinal beam 3 and the second small longitudinal beam 4 are parallel to each other, and one end of the first small longitudinal beam 3 is vertically welded and fixed to the left side of the second circular tube beam 2 in a wrapping posture. In the rear section, the other end of the...

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
