    • A manufacturing system is described for sequentially bending a plurality of planar spring elements extending from a regularly perforated bar or fret, then adjusting the resiliency of each element to provide a precise load when deflected to a particular position, and finally shearing only those elements meeting the desired deflection load criteria from the fret. A microprocessor obtains necessary processing data while controlling the several stations at which the spring elements are measured, formed (bent), thermally adjusted and sheared from the fret. A walking beam transport system also controlled by the microprocesser incremently transports the frets of spring elements between and through each station. An oven can be incorporated into the walking beam transport system between the forming and thermal adjust stations for stress relieving the spring elements before adjustment.Particular features of the system include a translating shuttle mechanism with a plurality of parallel rails for loading frets onto the walking beam transport system, linear cam actuators for moving load cells into engagement with a load arm extending from each spring element, a resilient deflecting guard mechanism protecting the sensor head of the load cells, and a precision bending mechanism in which a pair of pivotably mounted and orthogonally related linear bearing races support carriages translated by a pair of orthogonally related linear actuators for rolling a bending element around a cylindrical mandrel.The invented system and apparatus has particular utility for manufacture of the precision load arms which support flying read/write heads of disk drive data storage systems.
    • 描述了一种制造系统,用于顺序地弯曲从规则穿孔的杆或支架延伸的多个平面弹簧元件,然后调节每个元件的弹性以在偏转到特定位置时提供精确的载荷,并且最后仅剪切满足 理想的偏转载荷标准。 微处理器获得必要的处理数据,同时控制测量弹簧元件的几个站,形成(弯曲),热调节和剪切。 还由微处理器控制的步进光束传输系统在每个工位之间逐渐传输弹簧元件的弹簧。 可以在成型和热调节站之间的步进梁输送系统中并入一个烤箱,以便在调节之前应力消除弹簧元件。 该系统的特殊特征包括:具有多个平行轨道的平移轨道机构,用于将货物装载到步进梁输送系统上;线性凸轮致动器,用于将负载传感器与从每个弹簧元件延伸的负载臂相接合;弹性偏转保护机构 保护测力传感器的传感器头,以及精密弯曲机构,其中一对可枢转地安装的和正交相关的线性轴承座圈支撑由一对正交相关的线性致动器平移的滑架,用于将弯曲元件围绕圆柱形心轴滚动。 本发明的系统和装置具有用于制造支持磁盘驱动器数据存储系统的飞行读/写磁头的精密负载臂的特殊用途。
