Abstract
The invention discloses a backward deformation welding process method for the side beam of a bogie, which is characterized by comprising the following steps: firstly, carrying out track welding on an air spring seat board on the upper cover board of the side beam to form rigid fixing; and then welding the side beam. In the invention, the air spring seat board pairing process is performed before a side beam pairing process from a framework pairing process, the characteristic that the air spring seat board is similar to the upper cover board of the side beam in shape is utilized, and before the side beam is welded by a manipulator, the air spring seat board is subject to track welding on the upper cover board of the side beam to form rigid fixing, thereby effectively controlling welding deformation, improving product quality, improving production efficiency and reducing labor intensity.
Description
Technical field
The present invention relates to city rail bogie curb girder reversible deformation welding technique.
Background technology
At present, the welding after curb girder is formed the manipulator welding, before the framework one step welding of air spring seat board, this technology has three shortcomings: 1, postwelding curb girder upper cover plate air spring seat board place is sagging, must just can descend the step operation through adjusting before the framework assembly welding; 2, curb girder upper cover plate deflection is big herein, only can guarantee front end and air spring seat board in one plane during adjusting, forms a recessed pocket near the commissure, causes air spring seat board and curb girder upper cover plate fit clearance part excessive; 3, adjusting herein needs two people to cooperate, and a people uses the gas welding heating, and a people applies external force, and nearly about 1 hour consuming time, the low and serious waste human and material resources of production efficiency.
Summary of the invention
Technical problem to be solved by this invention provides a kind of city rail bogie curb girder reversible deformation welding technique, to improve the quality of products, enhances productivity, and reduces labour intensity.
For solving the problems of the technologies described above, the invention provides a kind of bogie curb girder reversible deformation welding technique, it is characterized in that: elder generation on the curb girder upper cover plate, forms air spring seat board tack welding one and rigidly fixes, and then the welding curb girder.
The present invention with air spring seat board group to operation being advanced to the curb girder group to operation from the framework group, utilize itself and curb girder upper cover plate similar characteristics of shape herein, before manipulator welding curb girder earlier with air spring seat board tack welding on the curb girder upper cover plate, forming one rigidly fixes, thereby effectively control welding deformation, improve the quality of products, enhance productivity, reduce labour intensity.
The specific embodiment
Take all factors into consideration whole city rail bogie frame assembly welding technique flow process, and in conjunction with curb girder upper cover plate and air spring seat board shape and thickness characteristics, adopt more reasonably technology utilization to face parts mutually and do one and rigidly fix, add an external force in advance to reduce welding deformation amount in the opposite direction of distortion.Optimize the framework assembly welding technique, with air spring seat board group to operation being advanced to the curb girder group to operation from the framework group, utilize itself and curb girder upper cover plate similar characteristics of shape herein, before manipulator welding curb girder earlier with air spring seat board tack welding on the curb girder upper cover plate, form one and rigidly fix, thereby effectively control welding deformation.
Claims (1)
1. bogie curb girder reversible deformation welding technique is characterized in that: earlier with air spring seat board tack welding on the curb girder upper cover plate, forms one and rigidly fixes, and then weld curb girder.
