Abstract (en)
[origin: EP0117851A2] The brake has a cylinder (1) which is bolted to the press frame. The cylinder houses a piston (2) which is acted on by compressed air. The piston rod (3) passes through an end cap (4a) into the bore of a hydraulic piston (6). The piston rod drives oil out of a chamber (5a) into an annulus (8), where the pressure acts on the hydraulic piston. The hydraulic piston has a wedge-shaped ridge on its opposite face, which is pushed into a matching groove in a shaft (9) by the oil pressure. The shaft is attached to the press ram which is thus held stationary.
