[Solenoid Application Example] Office machines and equipment - Electric stapler

Here is an example of applying the SDC type solenoid to an electric stapler.

Generally, a stapler that is manually operated is equipped with a solenoid to make it electric, and this diagram shows the state without excitation. By exciting the solenoid, the punch metal and needle case are pushed down, and the tip of the needle case comes into contact with the receiving metal and stops. The punch metal is further pushed down, and the punch section pushes out the needle to complete the punching. By deactivating the excitation, the punch metal and needle case are pushed back by the force of the return spring and plate spring, and the hinge lever returns to its original position, completing the operation. In this usage method, since the stroke length is relatively long, care should be taken to make the connection between the movable iron core and the hinge lever a long hole, ensuring that the movable iron core operates smoothly. *For more details, please refer to the PDF materials or feel free to contact us.*
