General conflict description:
Principle concept:
If traditional mechanical stamping is used to achieve high-precision microstructures, then manufacturing precision is improved, but production efficiency deteriorates due to long manufacturing times and continuous path modification
Why choose this principle:
The patent replaces traditional mechanical stamping systems with an electromagnetic stamping system. The electromagnetic device generates alternating magnetic fields that directly drive the stamping component, eliminating the need for complex mechanical transmission mechanisms. This substitution enables rapid stamping operations while maintaining high precision microstructure fabrication, thereby resolving the contradiction between manufacturing precision and production efficiency
Principle concept:
If traditional mechanical stamping is used to achieve high-precision microstructures, then manufacturing precision is improved, but production efficiency deteriorates due to long manufacturing times and continuous path modification
Why choose this principle:
The electromagnetic stamping device utilizes alternating current to generate periodic magnetic fields that drive the stamping component in a reciprocating motion. The stamping component moves between a first position (for stamping) and a second position (for separation) automatically with each AC cycle. This periodic action enables continuous high-speed stamping without requiring continuous mechanical path modification, thus improving production efficiency while maintaining precision

Abstract
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.
