company news about What is the integrated train axle and its manufacturing forging and upsetting hydraulic press and processing method?

The company develops an integrated train axle and its manufacturing forging and upsetting hydraulic machine and processing method, which is mainly composed of axles and left and right wheels. Its feature is that the axles and left and right wheels are forged and upsetted into an integrated axle by the support shafts at both ends, the left and right wheels and the connecting shafts between the left and right wheels. The processing method of the integrated train axle adopts a forging and upsetting hydraulic machine to implement the vertical protection force up and down and the forging and upsetting force increasing in the left and right horizontal directions on the billet of the stepped axle, so as to carry out the two fire integrated upsetting forming method. Beneficial effect: the vertical protective force of anti bending is adopted, which completely breaks the traditional principle of length diameter ratio of 1:2.5, and meets the requirements of the upsetting process of the integrated train wheel axle with the length diameter ratio of 1:5 gradually transiting to 1:2.5. Only two fires (6 minutes) can be used to upsetting a whole train wheel axle.
