Rotary swaging machine RK25

The rotary swaging machine RK25 is used for:

  • reduction, calibration and rotary swaging of pipe sections

  • reduction, calibration and rotary swaging of sleeves

The rotary swaging machine guarantees a form-fit connection which helps achieve, among other things, better strain-relief or tightness.

For workers of rotationally symmetric components the rotary swaging machine RK25 represents a consistent enhancement of existing systems for the rotary swaging of pipes & pipe ends, as well as for the rotary swaging of sleeves, shells, armatures and many other applications.

A typical example is the implementation of sensor sleeves which mechanically protect connection leads from being pulled out and seal them at the same time (IP67 possible). This procedure also allows crimping of plugs into sensor sleeves. Wall thicknesses of 0.2 mm up to 1.0 mm with a diameter of 3 – 25 mm are possible, depending on the material.

Machine setup

The handling of the rotary swaging machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a chuck or a gripper, which assures that it does not move while the jaws move in stages axially towards the work piece. After each pressing process, the jaws are turned by a variable degree. This ensures a completely round form according to the given die diameter.

The corresponding working parameters can be stored and managed in the machine control system. The user interface allows easy and logical operation. All essential processes are electronically monitored and the data is stored in the control system. This ensures high process safety and reproducibility.
