摘要:
The present disclosure relates to a bead breaker group for a tire mounting-demounting machine, which includes a support arm displaceable, in use, in two bead breaking directions along one bead breaking axis, and includes a pair of bead breaker tools supported on substantially opposite sides with respect to the support arm, thereby defining opposite work fronts directed away from the support arm, the work front of a first bead breaker tool of the pair of bead breaker tools being directed towards one bead breaking direction of the two bead breaking directions, whereas the work front of a second bead breaker tool of the pair of bead breaker tools is directed towards the other bead breaking direction of the two bead breaking directions.
摘要:
A device for automatic demounting of a tire from a rim having: a support arm (4); a demounting tool (10) articulated to the support arm (4); an attachment member (12) having one end articulated to the demounting tool (10) by a first articulation pin (13) and the other end thereof pivoted to the support arm (4) around a second articulation pin (14) extending substantially parallel to the first articulation pin (13); at least one extension appendage of the support arm (4) or a section (17) of the support arm (4), which extends beyond the second articulation pin (14); and at least one tie rod member (18) that is articulated on one side to the tool, and on the other side to the extension appendage or section (17) of the support arm (4).
摘要:
The present invention relates to a demounting device comprising a support member translatable along a movement axis (y-y), drive means for the support member, a tool-holder arm (3) borne by the support member (2), an abutment element (4) and a hook-like extraction member (5) both supported by the tool-holder arm (3), the abutment element (4) having a substantially flat work surface (4a), whereas the hook-like extraction member (5) is suitable for being moved in a substantially transverse direction with respect to the rotation axis (x-x) of a rim (W).

摘要:
The present invention relates to a bead breaker group for bead breaking a tire of a tired wheel equipped with rim with bead-engagement flanges, the bead breaker group comprising a support (2, 5) and at least one bead breaker tool (3) mounted for rotation around a pin (4) borne by the support (2, 5), the bead breaker tool being substantially flat and comprising: at least one portion configured as an abutment front (3b, 3d, 3f) against a flange of a rim of a tired wheel to be bead broken; and at least one portion having curved peripheral edge substantially coaxial with the pin (4) and intended to act as an engagement-penetration zone (3a, 3c, 3e) between the flange of a rim and the bead of a tire to be bead broken, the distance between the abutment front (3b, 3d, 3f) and the pin (4) being less than the distance between the pin (4) and the at least one engagement-penetration zone (3a, 3c, 3e).
