Technology CPUs: Feeder for a press based on static cam disks

  • Entry
  • Associated product(s)

The technological task is based on a press with connected feeder for stock feed. The rotary axis of the press is used as master axis for control of the stock feed via a static cam disk. The cam disk is developed and created in such a way that an exactly defined sequence between the continuously moving master axis of the press and the slave axis of the stock feed develops. In addition, a control signal for the gripper of the feeder is generated via an electronic cam switch on the master axis of the press.


The main task of this application for a Technology CPU is the development of a suitable cam disk for the synchronization of the feeder to the continuously moving rotary axis of the press. In this process a simple cam disk develops which is accompanied by further optimized versions.

Includes an S7 project as the core element of the demonstration system, consisting of the data for TO parameter setting, the programmed sequences realized with the STEP7 blocks and the WinCC flexible 2005 SP1 HF7 user interfaces.

The program archives can be used either without a drive connected or with a SINAMICS S120 Trainings case connected.
The required changes to the program to use the SINAMICS are described in the documentation part Demonstration
