Roemheld’s pull/push system facilitates die changes

Roemheld has developed a pull/push system that moves dies weighing up to 50 tons in and out of the press via a chain drive. It is screwed directly to the press bed, where the chain transports the die at a speed of 33 mm/sec. Faster versions with a maximum of 200 mm/sec. also are available.

If the press bed is high enough, the chain is mounted hanging downwards in the storage unit. Since the chain box is open at the bottom, it is insensitive to dirt. However, if the press bed height is too low to store the chain, a magazine storage is available, with the chain stored in a spiral.

Different racks can be adapted to the requirements of the production site. Ball or roller bars in the racks and changing carts, as well as in the transport consoles, help ensure safe, efficient die change.
