THE ORBITAL RIVETING TECHNOLOGY

A riveting tool, circulating under a constant angle and pressuring on the workpiece, is used during the working process. An orbital (taumel) riveting head with an inserted riveting tool circulates around the centre of the rivet. Thereof the axis of the riveting axis, leaning towards the axis of the machine, describes a cone in the area. The riveting tool thereby rolls the shaping rivet head. The pressure force of the tool must slightly exceed the firmness of the rolled material. Reshaping takes place in the following way: every time the tool passes, the workpiece is slightly imprinted with its material running evenly. The structure and firmness of the workpiece's material hardly change during such a procedure.

The orbital principle allows also for riveting problematic materials in terms of firmness. When one must create a riveting joint with porcelain, ceramics, steatite and similar, the pressure force of the riveting spindle must be adjusted in such a manner, that it is always somehow lower than the firmness of the workpiece. In such cases the duration of the rolling on the time regulator must be adequately prolonged.
