<p>The invention relates to a multiposition blading mechanism meant for the automatic blade change from the machine-tool to the storing station and reciprocally. According to the invention, the mechanism comprises a slide (1) driven by a hydraulic cylinder (3), said slide (1) accomplishing the translation of a blade from a machine-tool to a multiposition blading mechanism and reciprocally. A connecting hook (2) is also mounted on said slide (1). At the end of the rod of the hydraulic cylinder (3), there is mounted a toothed wheel (4) engaging a fixed rack (5) and a mobile rack (6), integral with the slide (1), thereby resulting a double travel of the slide (1) in relation to the travel of the piston of the hydraulic cylinder (3).</p> |
