Two kinds of gear punching molds: general and precision punching molds are described below respectively for reference.

Three commonly used gear punching processing methods: simple punching, precision punching and compound punching are described as follows, for reference.

The comparison of gear precision punching accuracy and ordinary punching accuracy in terms of minimum gear modulus, punching roughness, surface flatness, collapse, burrs, section taper angle and fillet radius are as follows, for reference and understanding.

Ordinary punching accuracy of gears: The quality of the shearing surface of the punching parts, the bending deformation of the punching parts, the tooth profile accuracy of the punching parts and the dimensional accuracy of the ordinary punching teeth are described below for reference.

The technical principles of gear fine blanking and ring gear press plate fine blanking are as follows, for reference and understanding.

The 4 stages of the gear punching deformation process: material compression deformation stage, material shearing stage, crack growth stage and material separation stage are explained as follows, for reference and understanding.
