摘要： An apparatus for straightening a U-shaped leaf spring wherein the spring includes a curved section having a concave side and a convex side and wherein the spring has a pair of elongated legs spaced-apart relationship with each other from the curved section of the spring and the curved section of the spring has a radius of curvature adjacent a side of the legs facing away from each other, the apparatus comprising a plurality of pivotal block members which simultaneously rotate counter to one another, each of the blocks having a channel disposed thereon adapted to receive one of the leaf spring legs therein and the channel having an outer wall facing toward the other block outer wall which extends away from the curved section of the leaf spring to a respective free end such that the combined lengths of the outer walls on both blocks are substantially the same length of the convex side of the curved section of the leaf spring; each block channel having a respective inner wall facing away from the inner wall of the opposite block and facing a concave side of the leaf spring legs and adapted to engage and provide support to the concave curved section of the leaf spring during the straightening process; a mechanism to rotate the blocks and straighten out the leaf spring; and a ram to support the curved section of the leaf spring.

摘要翻译： 一种用于矫直U形板簧的装置，其中弹簧包括具有凹面和凸面的弯曲部分，并且其中弹簧具有从弹簧的弯曲部分彼此间隔开的关系的一对细长腿， 弹簧的弯曲部分具有邻近腿部相对于彼此的一侧的曲率半径，该装置包括多个相互相对旋转的枢转块构件，每个块具有设置在其上的通道，其适于 以接收其中的一个板簧腿，并且该通道具有面向另一个块外壁的外壁，该外壁从板簧的弯曲部分延伸到相应的自由端，使得两者上的外壁的组合长度 块体的板簧的弯曲部分的凸侧的长度基本相同; 每个块通道具有相对的内壁，该内壁背离相对的块的内壁并且面对板簧腿的凹面，并且适于在矫直过程期间接合并提供对板簧的凹曲面部分的支撑; 用于旋转块体并拉直板簧的机构; 以及用于支撑板簧的弯曲部分的冲头。
