矩形钢丝及矩形钢丝钢丝圈的特性与制造工艺

Characteristics and processing technology of rectangular wire and its bead

介绍自主开发的胎圈用矩形钢丝及矩形钢丝钢丝圈的特点和制造工艺。矩形钢丝钢丝圈的主要生产工序有放线、整经、送头、定长裁断、捆扎和缠绕;结构特点为矩形钢丝表面不包胶,钢丝多股、多层紧密排列,沿圆周等分(等分处用薄钢带箍紧)。胎圈采用矩形钢丝钢丝圈的轮胎质量小、结构优、爆破压力大、行驶里程长。

The characteristics and processing technology of self developed rectangular wire and its bead are described. The main processing steps of rectangular bead wire include take-up, warping, end delivery,cut to-lenth,bundle-up and winding; and the structure features no coating rubber on rectangular wire, multi-strand and layer of wire arranged compactly and devided equally at circumference with bundles of thin steel tapes. The tire with rectangular bead wire has an advantage in less tire weight,optimum bead structure,greater explosion power and longer mileage.
