Description

Technical Field

[0001] The invention relates to the field of tire manufacturing equipment, and in particular to a continuous fiber composite material tire bead molding device and a preparation process. Background Art

[0002] With the rapid development of the automotive industry and lightweight high-end bicycles, as well as the growing emphasis on global environmental protection technologies, continuous fiber composites have become one of the key materials driving innovation in these two industries with their excellent lightweight and high-strength characteristics. Especially in the production of bicycle tires and automobile tire membranes, continuous fiber composites, with their excellent specific strength (i.e., the ratio of strength to weight), specific stiffness (i.e., the ratio of stiffness to weight), high designability and significant lightweight advantages, not only significantly improve the fatigue resistance and durability of the product, but also effectively reduce the rolling resistance of the tire, thereby improving energy efficiency and driving performance. Therefore, the application scope of this material in the design of high-end bicycle tires and advanced automobile tires is continuing to expand.

[0003] Compared with the traditional steel wire tire bead manufacturing process, the preparation process of continuous fiber composite tire bead is indeed more complex and delicate, involving a series of high-tech process steps such as precision molding, fiber winding and final shaping. In this process, the continuous fiber composite tire bead forming equipment plays a vital role, and it is the core tool to ensure the production of high-performance tire bead.

[0004] However, the loading and unloading operations of traditional tire bead forming machines require manual participation in the entire production process. Each production cycle starts with the manual installation of fiber materials, and the tire bead forming mechanism completes the forming process. The tire bead forming mechanism is driven by a cylinder to tighten four claws in four directions in a circumferentially evenly distributed manner; among them, the four claws of the tire bead forming mechanism are only suitable for products of one specification. When the product type is adjusted, the corresponding supporting claws need to be replaced, which brings inconvenience to the continuous production of the product. After the subsequent tire bead forming action is completed, the work of removing the outer tire is currently done manually.

[0005] The human factor has a great influence on traditional tire bead forming equipment, which has gradually shown its limitations in terms of precision, efficiency and stability, and it is difficult to meet the high standards of modern high-end manufacturing industry for high product quality, high efficiency and long-term stable operation. Therefore, the development of more advanced, efficient and adaptable continuous fiber composite tire bead forming equipment has become the key to promoting the sustainable development of this field, and is also an important support for the further lightweight and high-performance transformation of the bicycle and automobile industries.
