The present invention provides an angle punching device comprising: a base; an angle seating stand wherein an L-shaped angle is seated and installed in the base; and a press positioned on the angle seating stand, punching a hole in the angle seated in the angle seating stand by the operation of a cylinder. The press comprises: a press body vertically moved by a power of the cylinder; at least one pin guide hole penetrating through in an underside of the press body; pins separately inserted into the pin guide holes and moved to the top surfaces of the pin guide holes by a downward movement of the press body while coming in contact with a surface of the angle seated in the angle seating stand; pin height limitation holes penetrating through a front surface of the press body, and connected to the upper parts of the pin guide holes to be perpendicular in a horizontal direction; and a pin height limiting member selectively inserted into the pin height limiting holes, and punching a hole in the surface of the angle coming in contact with the pin by limiting the pin moved to the top surface of the pin guide hole while coming in contact with the angle. The purpose of the present invention is to provide the angle punching device capable of punching holes in the angle by simply adjusting an interval between the holes. |
