Electrical silicon steel sheets are commonly known as silicon steel sheets or silicon steel sheets. It is a soft magnetic alloy of silicon iron with extremely low carbon content, generally with a silicon content of 0.5-4.5%, made by heating and cold rolling. Generally, the thickness is below 1mm, so it is called thin plate. Adding silicon can improve the electrical resistivity and magnetic permeability of iron, reduce coercivity, iron core loss (iron loss), and magnetic aging. Mainly used to manufacture iron cores for various transformers, motors, and generators. The world's production of silicon steel sheets accounts for about 1% of the total steel production (see fine alloys). Generally speaking, silicon steel sheets belong to the category of sheet metal and are an independent branch due to their special applications. The following are the processing methods for silicon steel sheets:

1. Install the silicon steel sheet on the indexing spindle and press it tightly with a pressing head;

2. Punching molds for stator and rotor blades, and adjusting their orientation;

3. Every time the orientation of the dividing box is moved, the swing cylinder is activated to punch the slot holes of the stator and rotor of the silicon steel sheet one by one;

4. By adjusting the rolling screw, modify the spacing between the indexing spindle, the fixed core disk, and the punching die;

5. Drive the swing cylinder, rotate the double crank shaft 180 degrees, and reverse the orientation of the two inner sliders up and down. The present invention relates to a silicon steel sheet punching machine, which realizes the one-time installation of stator and rotor sheets of silicon steel sheets on the punching machine. The slot holes on the stator and rotor sheets are punched separately, saving auxiliary time, improving productivity, reducing investment, and lowering costs.
