Pressing jaw or pressing chain for a hydraulic or mechanical pressing device

摘要

Pressing jaw (1) or pressing chain (20) for a hydraulic or mechanical pressing device, for the pressing of a tube (24) with a tube-section-like pressing fitting (25), with two or more pressing elements (3) and a on the degree of fitting (25) is adapted to compress geometry of the pressing elements (3), wherein in a pressing element (3) in the longitudinal direction of the two pressing fittings (25) arranged next to another pressing zones (10, 11) of different pressing geometry are provided, of which a first pressing zone (10) a on the fitting (25) of annular bead (26) is assigned to the fact that both pressing zones (10, 11) in order to achieve a uniform deformation of the first pressing chamber, that the inner sealing element with respect to contact pressure and pressing surface is almost uniformly to the surrounding surface areas of the first ringnutartig pressing zone and of the coaxially lying pipe section comes to rest, with a non-circular pressing geometry are formed, the deviation from an imaginary circular line, in each case via at least 80% of the circumference is provided, characterised in that the first pressing zone (10) in its form as a ring groove in its axial width (b) deviates in a wave shape.
