Description
Technical field
The present invention relates to motor train unit bogie anti-side rolling torsion rod axis processing technique field, specially a kind of motor train unit bogie
Anti-side rolling torsion rod axis surface rolling technique.
Background technique
Rail vehicle in the process of running, can inevitably generate double swerve or car body runs unbalanced situation, therefore
It needs that anti-side rolling torsion rod is installed on bogie, by the torsional deflection of torsion bar, limit car body sidewinders angle, makes the heavy of car body
Transportation by driving move it is unaffected, to prevent slide-out.Wherein, torsion bar shaft is crucial important one of part in anti-side rolling torsion rod, is turned round
The quality of bar axoplasm amount directly affects the performance of anti-side rolling torsion rod.EMU anti-side rolling torsion rod belongs to thin and long shafts, draw ratio
Greatly.Torsion bar shaft conventional machining uses the processing technology of turning, grinding, but traditional machining processes are difficult to reach the surface of design requirement
Therefore roughness for this problem, in torsion bar shaft process, need to take effective processing technology, we design one
Kind motor train unit bogie anti-side rolling torsion rod axis surface rolling technique is necessary.
Summary of the invention
The purpose of the present invention is to provide a kind of motor train unit bogie anti-side rolling torsion rod axis surface rolling techniques, make torsion bar shaft
Surface roughness reaches design requirement, and after torsion bar shaft surface rolling processing, strengthened ultimate strength conjunction yield point increase on surface layer,
Hardness and wearability are all improved, and service performance, anti-fatigue performance and the corrosion resistance of torsion bar shaft are all significantly improved, simultaneously
Processing quality, the production efficiency of torsion bar shaft are improved, and greatly reduce production cost.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of motor train unit bogie anti-side rolling torsion rod axis surface rolling technique, comprising the following steps:
S1, rolling device is mounted on lathe cutter saddle planker；
S2, machine tool dragging plate drive rolling device length feed, carry out floating rolling to workpiece surface；
S3, rolling device are divided into three angles and roll to workpiece.
As a further solution of the present invention: the rolling device includes idler wheel and hydraulic cylinder, and the idler wheel is provided with
Three, and three idler wheels are angularly uniformly arranged on the outside of workpiece, the idler wheel is defeated by shaft coupling and hydraulic cylinder
Shaft transmission connection.
Beneficial effects of the present invention: rolling device is mounted on lathe cutter saddle planker, drives length feed by machine tool dragging plate,
It realizes the floating rolling of workpiece surface, torsion bar shaft surface roughness is made to reach design requirement, after torsion bar shaft surface rolling processing,
The surface layer ultimate strength that strengthened is closed yield point and is increased, and hardness and wearability be all improved, the service performance of torsion bar shaft, resist it is tired
Labor performance and corrosion resistance are all significantly improved, while the processing quality of torsion bar shaft, production efficiency are improved, and significantly
Reduce production cost.

S3, rolling device are divided into three angles and roll to workpiece；
Wherein, rolling device includes idler wheel 1 and hydraulic cylinder 2, and there are three the settings of idler wheel 1, and three idler wheels 1 are angularly equal
Even to be arranged on the outside of workpiece, idler wheel 1 is sequentially connected by the output shaft of shaft coupling and hydraulic cylinder 2, and hydraulic cylinder 2 is idler wheel 1
Power is provided, while adjusting the size of rolling power by the charge oil pressure of control and regulation hydraulic cylinder 2.
The working principle of the invention: rolling device is mounted on lathe cutter saddle planker, drives length feed by machine tool dragging plate,
It realizes the floating rolling of workpiece surface, torsion bar shaft surface roughness is made to reach design requirement, after torsion bar shaft surface rolling processing,
The surface layer ultimate strength that strengthened is closed yield point and is increased, and hardness and wearability be all improved, the service performance of torsion bar shaft, resist it is tired
Labor performance and corrosion resistance are all significantly improved, while the processing quality of torsion bar shaft, production efficiency are improved, and significantly
Reduce production cost.
Present invention disclosed above preferred embodiment is only intended to help to illustrate the present invention.There is no detailed for preferred embodiment
All details are described, are not limited the invention to the specific embodiments described.Obviously, according to the content of this specification,
