Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a device for pre-deformation treatment of tire bead. Background Technology

[0002] With the rapid development of the logistics and transportation industries, market demands for tire performance are becoming increasingly diversified, especially for short- and medium-haul truck tires, which require characteristics such as safety, wear resistance, and high load-bearing capacity. The all-steel secondary forming process helps meet these demands, producing tires with higher carcass cord density and better bead forming, thus improving tire durability and safety. However, in the secondary forming process, due to the high stiffness of the bead, it is prone to wrinkling during the inverted drum pressing, affecting product performance and processing performance. Therefore, pre-deformation treatment of the bead is necessary, requiring pre-bending of the bead. However, current technology lacks a device capable of pre-deforming the bead. Utility Model Content

The first arc-shaped fixing ring 4 and the second arc-shaped fixing ring 5 are at the deformation points of the tire bead. Their outer dimensions are consistent with the tire bead dimensions to ensure that the tire bead's outer shape deforms and matches the arc-shaped fan surface after being placed statically under the influence of gravity.
