tooling system

The multi-die tooling makes FEA-optimised end designs a reality
Tool access and die set change
The quicklift function provides comfortable and fast access to the die area at the convenient height of 1400 mm ( 55” ).
Spring-loaded rollers, which lift the tooling from the slide plate once the fixing screws have been loosened, allow the tooling to be changed easily and fast.
Using a special tooling carriage tooling change over can be done by one operator.

END-O-MAT multi-die tooling  
The individual tools are mounted on the column die set and centred at the manufacturer's plant. The centring rings are then fixed and secured against dislodging. The individual tools need not be recentred at the customer's plant - a fact which facilitates their easy replacement. Tool changes are further simplified by the fact that each toolset, this means both top and bottom tools, is fastened by one central screw. The tooling is provided with carbide cut edges to ensure a long lifetime. The approximate service life of the tooling is about 5 million ends for each individual toolset for unwaxed, chromiumplated DR material. The dies can be reground about 20 times with about 0.2 mm each so that about 100 million ends can be produced by each individual toolset. Lacquered sheets need not be greased or waxed for this type of tooling. With waxed or tinplated lacquered material the lifetime can even be two or three times longer!
Sheet holders, blank holders and ejectors are powered by compressed air or nitrogen. There are no mechanical springs with their typical problems. The forces for the above elements can be set from outside by means of pressure regulators.
The stamping press has been dened with fast tool changeover in mind. The complete tooling can be pulled out of the machine through an opening in the narrow side of the press. Spring-loaded rollers which lift the tooling from the slide plate once the fixing screws have been loosened allow the tooling to be pulled out easily on a simple change carriage. Then the new tooling is pushed from its carriage onto the slide of the stamping press. Index pins in the bed of the stamping press ensure correct positioning of the tooling in the press. Manual alignment is not required.
Once the kickers have been set, sheet centring has been checked and a new program has been retrieved from the controller the stamping press is ready to resume operation. Replacement does not take longer than about 30 minutes; the time required for diameter changeover is less than 1 hour, with trained staff.
