Claims

[Scope of utility model registration request]

In the separate type, which shears and separates a workpiece that has a wall surface almost perpendicular to the top surface on the outer periphery,
A pair of rotating shafts perpendicular to the shearing surface are provided outside the wall surface to be sheared on the upper holder that is displaced perpendicular to the top surface, and the inner sides of the rotary blades reach the inner side of the wall surface, respectively, on these rotating shafts. A pair of rotary cut punches are rotatably mounted, and between the pair of rotary cut punches of the upper holder,
A separate type characterized in that a fixed cut punch having a fixed blade that reaches at least the inner side of the rotary blade of the rotary cut punch is fixedly installed.
