The holder is designed for use with a single piece die insert (max width 400 mm, length 500 mm, height 60 mm).
The upper and lower die holders are fixed to the press ram and press bed using fixing bolts. The holder is fitted with
a heating system, a guide arrangement and additional impact faces.
The die inserts are clamped to the die holders at the top
and at the bottom using, in each case, one Feuerbacher tensioning key. For changeovers only the inserts are replaced. The die holders remain in the press.
Any offset of the dies can be corrected using shims at the clamping faces of the inserts.
Systems of this kind have been provided for presses with force ratings up to 6000 tons.
Mechanical and hydraulic presses
Feuerbacher tensioning keys can also be employed on other types of mechanical and hydraulic presses.
