Abstract

See full text

An electromagnetic stamping apparatus includes a work platform configured to load a work piece. A stamping component is coupled to the work platform and has a first position and a second position. The stamping component includes a stamping rod and a stamping head. The stamping head stamps the work piece on the first position. An electromagnetic device is coupled to the stamping rod and generates a magnetic force according to an alternating current to push the stamping component to the first position to make the stamping component stamp the work piece. A compression spring pushes the stamping component to the second position according to the restoring force of the compression spring. Wherein, the magnetic force is greater than the restoring force of the compression spring to make the stamping component stamp the work piece twice in every waveform period of the alternating current.
