Device for forming a hollow profile or part trabajosimilar, by way of conformation to high internal pressure.

摘要

Device for forming a hollow profile or similar workpiece, which is structured as a hollow single-chamber or multi-chamber profile by a high internal pressure generated in the space profiled sealed, and on which a mold is applied male, by means of action able to circulate, with a portion (40, 40b) sealing male mold made of a limitedly flexible synthetic material, and which is insertable into the profile space (12) of the hollow profile or the workpiece (10), characterized in that on the periphery of the part (40, 40b) of the male mold is provided at least one additional element (54, 54e, 58) made of a material with high mechanical strength , which together with the male mold part limitedly flexible on the outside an area that can be applied to transfer to the hollow operating position profile.
