Rotary Swaging Machine UR 8-4-DD-50LH-CNC
Our rotary swaging machine is a recess hammering machine with 4 dies of the company HMP type UR8-4-DD-50LH-CNC, which is suitable for recess and infeed swaging, as well as axial/radial forming. It can be divided roughly into three main assemblies: the radial forming-unit, also known as swaging unit, the retrofitted CNC-control Siemens S 7 and the axial feeding unit.
The workpiece is fed through the feeding system into the swaging unit where the surrounding case is spinning to adjust the forming die under a compulsory mechanism.
Furthermore the swaging machine has an inductor which allows the workpiece to be heated up before being fed into the swaging unit. It also consists of a counterholder for additional compression and guidance during forming. Besides the main axle, the swaging machine also has two mandrels which can be used for both-sided forming of the inner contour. The force- and path-controlled movement of the mandrels allows a great variety of shapes for the processed workpieces.
- Max. tube diameter: 95 mm
- Swaging frequency: 30 Hz
- Max. axial force: 400 kN
- Max. radial force: 1000 kN
- Axial infeed: 0 …3 m/min
- Axial traverse path: 915 mm
- Working stroke: 0,7 mm
- Number of dies: 4
- Induction power: 70 kW
The feeding system provides a maximum traverse path of around 915 mm with an exact positioning of 0,02 mm and an infeed between 0 m/min and 3.0 m/min.
Maximum axial force of the feeding system is 400 kN.
Rotary Swaging Unit
The rotary swaging unit is, dependent on the tool, suitable for tubes with an outer diameter of minimum 10 mm and maximum 95 mm and 8 mm to 55 mm for solid materials. The machine allows a radial infeed of 13 mm for every toolset. The working precision on the outer diameter is at around 0,1 mm to 0,2 mm, meaning a tolerance class of IT11 to IT13.
At an impact frequency of 29 Hz the working stroke is approximately 0.7 mm. Maximum force on each die is roughly 1000kN.
