Automatic Wheelset Mounting Cell For EMU And Metro Wheelset Maintenance

Wheelset Assembly Cell Assembly Line

Application scope:
This Wheelset mounting cell is mainly applicable for the automatic assembly of EMU and Metro wheelsets with gearbox, also for the mounting of the wheels and brake discs for passenger cars. One positioning to proceed the mounting of both wheels and brake discs.

The Wheelset Assembly Cell mainly consists of:

• 1 set of wheelset press with double cylinders
• 1 set of Wheel (brake disc) conveyor line
• 1 set of Axle conveyor line
• 1 set of manipulator for picking wheels and brake discs.
• 1 set of wheel pverturning and pre-assembly machine
• 1 set of wheelset transferring trolley for transferring the wheelset from pre-assembly machine to the wheelset press
• 1 set of wheelset transferring trolley for transferring the wheelset out from the wheel press.

Technical parameters of the Wheelset Press:

(*Remarks: Above parameters are indicative, and can be modified as per customer's requirements. The customer shall provide the detailed wheelset drawings for the design work after the contract awarded.)

Performance Features of the Wheel Mount Press:

• Automatically mount the 2 wheels on the same axle simultanously without turning the axle and in a sequence first the wheel at one side of the axle then the wheel at the other side
• Automatically control the inner distance and wheel position tolerance.
• Siemens S7-300 PLC and AdvanTech Industrial computer to control and achieve the fully automatic pressing operation.
• Both automatic and manual mode are available.
• The wheelset press 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 measurement unit will automatically detect and collect the relevant data and display it on the screen.
• Automatic recording of mounting curve
• Overall gantry frame structure, with high strength, good rigidity and less deformation.
• Movable resistant column.
• Double ram cylinder pressing.
• Unique Invention patented cylindrical ram for wheel mounting, with high pressing accuracy.
• Special patented centring mechanisms for center hole positioning.
• Standard roll-in or pass-through design.

Overview of Hubei Heqiang:
Hubei Heqiang Machinery is the No.1 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 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.
