Claims

[Scope of utility model registration request]

A cutting device is installed at the back end of the material insertion section of a crank press that has a roughly C-shaped main body frame. The cutting device sequentially cuts the material waste after punching the product by operating the upper blade later than the punch by a lifting rod provided between the shank supporting the punch and the column of the main body frame. Like that, a crank press.
