NEW GENERATION
REPKON RDM - SERIES

The production of wheel discs for off-road vehicles, trucks, construction or agricul-tural vehicles can be done in a very efficient way by using spinning, shear for-ming and flow forming technology. Starting from a round pre-form with cen-ter- and bolt-holes a combination of these technologies is forming in one pass the finished work-piece. With the advantages of these proven cold forming technologies the design of the disc can be optimized to get a work-piece with reduced weight, first class properties and low costs.
 
Principle of flow forming discs

REPKON has engineered and designed a machine that covers all technologies for forming a high quality wheel disc. In a winning combination of long proven experience in metal for-ming with high-tech and state of the art solutions we developed a machine meeting the high customer specific requirements concerning productivity and return on investment.

The REPKON RDM Series is the best solution for the production of optimized wheel discs because of its technological advantages and its production capacity of up to 180 discs per hour. The RDM Series are covering a diameter range of 15” to 40”, a width range between 6,5” and 28” and a wall-thickness of the pre-form up to 25 mm.

Outstanding design advantages

  • Each forming-roller is independently mo-ving by a radial- and an axial-cylinder. Hence each roller has its optimal forming path and spinning, shear-forming and flow-forming can be done in one set-up.

  • Special bolts in the tooling fix the pre-forms. Together with the position control of the main-spindle thus allows using maximum torque during the hole forming process.

  • The easy accessible tool area, the top-loading device and the unloading of the finished work-piece under the machine bed are reducing the idle-times signify-cantly.

  • The special pre-form thickness measuring unit is ensuring a high precision pro-duction by remarkable tolerances of the pre-form.

  • The alignment of all cylinders at the level of the machines axis avoids any bending in the machine and ensures quality of the process.
