ROEMHELD: Solutions for quick die change in automatic punching machines and high-speed presses

New catalogue

Hilchenbach, 15 of July, 2019. With the new catalogue “Everything for quick die change in automatic punching machines and high-speed presses” ROEMHELD addresses prospective customers from the metal forming industry with presses between 30 and 300 t. The set-up time optimiser shows clamping elements and changing technology that protect the die, improve workpiece quality and increase productivity. They are specially designed for the limited space available on small press tables. Since dies often cover these completely, there are very few quick clamping systems on the market so far.

Particularly small clamping elements for T-slots from 12 mm

ROEMHELD has extended its series of hydraulic and mechanical clamping elements to include lower sizes for use on small press tables. The range includes sliding clamps, hollow piston cylinders and hydro-mechanical clamping nuts with clamping forces up to 30 kN - with a diameter of only 50 mm. They are suitable for installation in T-slots from 12 mm.

For precarious space conditions, the company also offers magnetic clamping plates that are permanently installed on the press table. This allows dies of any size and geometry to be securely clamped in seconds - even when space is completely limited for the use of other clamping elements.

With the aid of roller and ball bars, which can be used to move the die effortlessly, set-up can also be simplified and accelerated. ROEMHELD has expanded its product range accordingly for use in press tables in automatic punching machines and high-speed presses. Die changing carts with a load of up to 1,600 kg complete the range.

Solutions for short set-up times even on small press tables

Andreas Reich, Product Manager Die Clamping Technology, sees great potential for increasing productivity with little effort when changing dies in automatic punching machines and high-speed presses. In many cases, dies are still clamped with screws. With fatal consequences, Reich says: "This does not only take a long time - the die is also often ‘distorted’. Thus the product output suffers and upper dies wear out very quickly. Simple hydraulic or mechanical clamping elements are quickly retrofitted and pay for themselves within a short period of time."
