The tire tread of the waste heavy-duty tire casing is usually close to the completion of abrasion, only the casing and the tire bead part are left, the casing part is usually deformed and damaged in different degrees due to abrasion, tire burst and the like, but the tire bead cannot be deformed and kept complete, the reason is that the steel wire ring formed by the high-strength steel wire and the filling rubber can bear various interaction forces of the casing and the rim, and the tire casings of different specifications can be sorted and sorted by measuring the diameters of the tire beads because the tire beads are not deformed and damaged.

The inventor finds that, as is known in the technical field, the support of the workpiece clamp cannot be removed by adopting a machining mode, whether the workpiece clamp is used for clamping firmly and reliably and the accurate positioning of the workpiece is guaranteed to be closely related to the selection of the clamping part of the workpiece, and the tire bead is undoubtedly an ideal part which is suitable for clamping and positioning in the waste tire, so that the waste tire can be reliably clamped and the design difficulty of the clamp is reduced. The tyre bead is a steel wire ring formed by high-strength steel wires and filling rubber, the tensile strength and the surface hardness of the high-strength steel wires in the steel wire ring are high, the high-strength steel wires are not easy to break mechanically, and cord fabrics in the tyre body are usually made of thin high-strength steel wires or synthetic fiber hanging rubber and can be broken mechanically.
