500 Ton Double Cylinder Wheelset Press , Fully Automatic Wheel Press

250~500 Tons Fully Automatic Double cylinder Wheel set Press

Machine Overview:

Hubei Heqiang Machinery is the leading manufacturer of wheel set press machines in China. It offers the most advanced wheel set pressing equipment available in the railway and other relevant industry. The wheelset presses are used to mount and dismount all of the elements on the axle (wheel discs, brake discs, gears and bearings). With both single and double cylinder version available for option and capacity range from 200 to 800 tons. Our vast range of machines can satisfy all customer requirements in both maintenance and mass production applications.

Our fully automatic double cyliner wheelset press is the most advanced wheel press machine available on the market today. Available in capacity ranging from 200 to 500 tons. This machine features a precisely positioned cylinder on each side of the machine along with our state-of-the-art measuring system that utilizes a high-tech servo system and a series of analog laser measuring devices to position each wheel-set component with high precision. All tooling is specialized and easily exchanged to safely accommodate a large variety of wheel set components and configurations. A rotation device are optional to be supplied with the machine to perform wheel back-to-back, axial run-out and radial run-out measurements after the mounting process has been completed. 

Application scope:

The fully automatic double cyliner wheel set press is used to mount, dismount and back pressure testing wheelset wheels, brake discs, gear on to / off of the axles for all types of railway vehicles (such as passenger cars, wagons, metros, intercity cars, high-way rail, EMU etc.). It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time) in required format. 

Technical parameters:

(*Above parameters are indicative, and can be modified as percustomer's requirements.)

Machine features:

• The Machine is a horizontal hydraulic wheel press and will be installed in a pit. (The model without pit is also available.)
• The Machine is able to mount/dismount both wheels on the same axle without turning the axle and in a sequence first the wheel at one side of the axle then the wheel at the other side.
• The Machine will be able to complete the mounting/dismounting of two wheels onto / off the axle simultaneously once the wheels have been loaded onto the Machine.
• The Machine can be designed to mount/dismount wheels, bearings, gear wheel and brake discs onto axle with high automation and easy operation.
• Gantry frame structure, with high strength, good rigidity and less deformation.
• Double-end cylinder pressing. Only need one positioning without reversal of the axle to proceed both sides’ wheel mounting/dismounting.
• The Machine is equipped with special patented centring devices at both ends of two ram cylinders for center hole positioning. The centre can insert into the center hole of both ends of the axle for wheelset positioning. During the whole operation process, it can ensure that the axle center line will be completely concentric with the two ram cylinder centerline to make the ram end face fully matched with the axle end face, without damage on axle center hole and preventing axle from upsetting.
• Unique Invention patented cylindrical ram for wheel mounting, with high pressing accuracy. The wheel mounting requires high accuracy and high pressing force. In order to ensure that the parts blocking the wheel are subjected to the force completely symmetrical, we adopts cylindrical ram for mounting wheel, not the side opening baffle.
• The Machine is equipped with an electrical axle lifting jack for wheelset pre-assembly and loading/unloading onto/off from the Machine. It will exit from the Machine during the mounting/dismounting operation.
• The Machine is equipped with a gearbox support to support the gearbox during the whole mounting/dismounting process.
• The Machine can track and control the whole process, detect the pressing condition of the
  wheelset, and analyze and process it through industrial computer. It can export the pressure vs displacement curve and other results onto the screen and printer.
• The Machine is designed with acoustic-light alarm to ensure the safe and reliable operation.
• High pressure oil injection pump is available for option;
• Applicable to the wheelset with standard, narrow, meter and board gauge.
