    摘要： Dimpling of a workpiece by rebounding of a magnetic repulsion punch mechanism, when operated at high punching rates, is avoided by application of a damping pulse at a point at or subsequent to a mid-point of a return stroke of the punch from the workpiece and preferably within the last 10% of the return stroke. This damping pulse is preferably a fraction of the pulse width and of approximately the same amplitude as a driving pulse applying kinetic energy to the punch for causing punching of the workpiece. At high punching rates the kinetic energy of the return portion of a punching stroke is substantially determined by elastic rebounding of the punch from a guide bushing. The removal of kinetic energy during the return portion of the stroke allows the return of the punch to a position close to a rest position during a very short interval with small overshoot under control of mechanical damping. Since dynamic damping may be substituted for much of the mechanical damping in the punching arrangement, high quality punching may be accomplished at much increased punching rates. A preferred form of monitoring punch position employs RF reflected inductance and may be used to form a time expanded image of punch movement.

    摘要翻译： 通过在高冲压速度下操作时通过弹性冲击机构的回弹来对工件进行刨削，通过在来自工件的冲头的返回行程的中点处或之后的点处施加阻尼脉冲来避免， 最好在返程行程的最后10％内。 该阻尼脉冲优选地是脉冲宽度的一小部分，并且与向冲头施加动能以对工件进行冲压的驱动脉冲大致相同的幅度。 在高冲击速率下，冲压行程的返回部分的动能基本上由冲头从导向衬套的弹性回弹确定。 在行程返回部分期间移动动能允许在非常短的间隔期间将冲头返回到靠近静止位置的位置，在机械阻尼的控制下具有小的过冲。 由于动态阻尼可以代替冲孔装置中的大部分机械阻尼，所以可以以更高的冲压速率实现​​高质量的冲压。 监测冲击位置的优选形式使用RF反射电感，并且可以用于形成打孔移动的时间扩展图像。

    摘要： A magneto repulsion electrical tape wound coil has been developed with improved current distribution and improved heat transfer. The coil is easy and is expensive to manufacture and simple to mount. The coil comprises a conductive strip (e.g., a copper strip) with rectangular openings stamped in it with a standard metal stamp. The single row of openings are at regular intervals and arranged so that the width of the openings and the spacing of the openings is such that when the coil is wound there is an overlap of the openings, forming radial passages extending from the outer periphery of the coil to its central core electrode. Cooling fluid may be supplied from a hollow inner electrode so that the cooling fluid flows radially, outwardly. Since the openings overlap to form radial passages, a cross-flow path for the cooling fluid may be established where fluid enters the passages on one side of the coil and exits from the other side of the coil.
