Automatic CNC Hydraulic Wheel Press with Double-end Cylinders - Model HQ01
1. Application scope:
This Wheelset Press is applicable for the mounting and dismounting of the railway wagons wheelsets.
2. Machine Features:
- Gantry frame structure, Dual-end cylinders, special anti-upsetting centres and movable resistant column, with delicated trolley for splicing and feeding. It's suitable for assembly line.
- Full Automatic control, CNC operating system, easy to learn, achieving the convenience and visualization of operation;
- High accurate measuring device, ensure that both wheel inner distance and wheel position difference reach the relevant requirements;
- Multiple function of system software, including wheel calibration function, function of automatic record, intelligent judgement, print, save and query to wheel pressing curve of pressure vs displatement.
- Unique hydraulic servo system, adjustable pressing speed, it can realize the mounting, dismounting and beack-pressure test of various types of wheelset.
- Center hole positioning, pressing without turning the axle, shorten the working time and improve the process efficiency.
