Reducing interference on force measurements in progressive headers
Eldes designs, installs and services cold headers and thread rolling machines. In its Prometeus 2K equipment a patented method has been incorporated to mathematically reduce the amount of the interference of each station on the other, thus improving the efficiency of the overall process control in progressive headers.
The measurement of the force applied to the product during cold forming has been recognised as a very efficient process control method for cold headers. In many cases this measurement is indirect and the sensor receives only a fraction of the force under control.
When there is only a single applied force, the only consequence is that the indirect sensor measures a value which is proportional to the real force, but the scale factor is usually unknown. This happens because usually the operation of the structure is within the elasticity limits; the proportionality factor can be determined by experiments, if it is needed. This is the case in a process with only a single production station, where the machine applies a single force to each phase.
In the case of progressive headers, the machine simultaneously applies different forces in each working station, and the value measured by each sensor will not reflect just the force developed in its
own station. In fact each station suffers interference produced by the forces relevant to the other stations. Integrating Prometeus 2k in the process will reduce the interference.
