Description

Train wheel pair marking machine

Technical Field

The utility model relates to the technical field of train wheel marking, in particular to a train wheel pair marking machine.

Background

The wheels are used as the contact parts of rolling stock and steel rails, and after production, related data such as diameter and tonnage are carved on the side surfaces of the wheels, so that maintenance staff can assemble the wheels on the bogie for different types of wheels and regularly carry out maintenance. At present, the wheel mark is to manually paint the wheel to make anti-creep lines or parameter marks, and mostly manual hand painting or paint spraying is adopted. These modes appear to be debilitating and inefficient in the face of large-scale mechanized production activities. Meanwhile, paint marks are easy to flow downwards, so that marks are fuzzy, a great amount of time is required for waiting on the metal surface in air drying, the waiting time required in the south with wet weather or in winter with cold air temperature is longer, and more importantly, the paint marks are easy to fall off in the use of wheels, and the production activity is greatly influenced.
