[0002] The relay iron core is an important component of a relay and is mainly used for enhancing a magnetic field generated by a coil, so that the magnetic force is more concentrated and stronger, thereby better attracting an armature and a contact. The iron core is usually made of iron or steel material, and the function of the iron core is to enhance the magnetism of an electromagnet, so that the magnetic field of the energized solenoid and the magnetic field of the iron core are superimposed on each other, thereby significantly enhancing the magnetism of the solenoid. The existing iron core is composed of multiple pieces, and this mode makes the iron core processing more complex and is not conducive to improving the processing efficiency. However, the iron core stamping is difficult to complete one-time forming operation and needs to be processed multiple times.
