  • Patent number: 5911806
    Abstract: A groove stamping machine stamps the required grooves successively into a disk-shaped blank particularly for manufacturing stator and rotor plates for electric machines. The groove stamping machine has a stationary bench which, on the end side, carries a spacing apparatus for receiving the blank. A stamping device disposed on the bench is adjustable with respect to the spacing apparatus. The distance between the spacing apparatus and the stamping device can be adjusted by a ball thread spindle which acts between the spacing apparatus and the stamping device. The fixing of an adjusted distance takes place by the blocking of the ball thread spindle, preferably by way of a disk brake. The stamping device is disposed via a combined roller slide bearing on the bench which permits a low-friction displacement of the stamping device which also supporting the latter in a stiff manner.
