Embodiment Construction

[0035] With reference to the cited figures, the device according to the invention, generally designated by the reference numeral 1, is applied to a tire removal machine 100 comprising a foot 101 on which is mounted a A table or spindle 102, on which the rim 200 or wheel (rim+tyre) to be processed is fastened by means of a suitable locking system.

[0036] The axis of rotation of the wheel or rim is generally vertical, as in the examples of construction shown herein.

[0037] The machine 100 is provided with an arm 103 mounted on rails and movable in a radial direction (typically horizontal) relative to the main shaft 102 .

[0038] By means of appropriate actuation (pneumatic, mechanical, hydraulic, etc.), the arm / support can be moved in a direction parallel to the axis of the main shaft 102 .

[0039] The device 1 according to the invention is mounted on an arm 103 of a machine 100 .

[0040] The device 1 has a pliers 2 pivoting in the tool body 3 and able to grip a bead 30...

Abstract

A device for mounting and removing a tire on / from a rim includes a pincers element which is pivoted in a tool body with respect to the main frame and can grip a tire bead; the pincers element performs a preset rotation together with the tool body, moving away from the rim edge by performing a motion over the edge without making contact with the rim at the end of the rotation; the pincers element releases the bead on the outer edge of the rim, in a removal operation, or in the inner seat of the rim, in a mounting operation.

Description

technical field [0001] The invention relates to a device for mounting and removing tires on rims. Background technique [0002] The operation used to remove and mount the tire from the rim requires a great deal of attention from the operator as it is difficult to assess the air force applied to the tire to complete the operation; and the risk of damage to the rim itself. [0003] The automatic installation / removal systems used in tire removal machines to date are systems that have used up to 2000 times leverage manually instead of the usual hooks, claws or tools. Once inserted, such tools extract the bead by the force of the cylinder between the rim edge and the tire bead, moving the bead beyond the rim edge when the motion of the cylinder used for insertion is reversed. [0004] Therefore, in most cases a stronger force is applied to the bead of the tyre, since the hook / claw is interposed between the rim and the tire and is forced to withdraw (moving) during the transitio...
