Description

Technical Field

[0001] The invention belongs to the field of manufacturing equipment for tires with wire rings, and particularly relates to a cold-applying machine for apex rubber and a use method thereof. Background Art

[0002] In the existing production process of tires with wire rings, the initial tire bead needs to be attached to the periphery of the wire ring. If the number of tires produced in the same batch is small, cold attachment is usually used. The existing cold attachment process includes the following steps: the wire ring is attached to the center of the forming and attaching plate, the apex is attached to the forming drum, and the forming drum is operated to move the forming drum forward. When the forming drum contacts the center of the forming and attaching plate, the forming drum expands, the apex is flipped up, and the inner diameter is expanded, so that it is attached to the periphery of the wire ring to form the initial tire bead. The forming drum is reset and retreated to its original position, and the initial tire bead is removed from the center of the forming and attaching plate, thus completing the production of an initial tire bead. The removed tire bead usually needs to be laid flat and stacked to prevent deformation. Figure 4 Because the shape of the apex results in one bead being conical and the other being flat, the bead must be stacked with the conical surface facing upwards. A hard pad must be placed between the beads to ensure the pad supports the bottom surface of the bead, thereby preventing the rubber of the bead from deforming. In the existing cold-lamination process for apex beading, manual labor is required for applying the wire bead, unloading the bead from the forming and laminating plate, and stacking the beads. To reduce the workload of operators, the goal of technological innovation in this field has been to design an automatic cold-lamination machine that can automatically apply the wire bead, unload, and stack the beads.
