Title: TOOLING FOR FOLDING PRESS FOR AIR FOLDING
Abstract:
The tooling is comprised of two half-dies (1, 1') arranged so as to slide on respective parts (12, 12') of the press table, on either side of the folding plane (23). The actuation device for closing the die includes two assemblies of pairs of inclined shims (9, 10; 9', 10'), each of the shims of one pair being fixed respectively one (9; 9') on the half-die and the other one (10; 10') on a traction member (11; 11') connected by an automatic drive device controlled by a programmable electronic device. The opening of the die is effected by the action of a spring steel blade (19) arranged in the bottom of the folding V.
