摘要： A punch for a punch press includes a punch holder which is installed on a punch installing portion of the punch press and a plurality of punch bodies so supported on the punch holder as to be independently movable in the vertical direction. Shearing blade portions are formed on the lower ends of the respective punch bodies. The shearing blade portions have elongated configurations, each extending in a different direction in the horizontal plane.

摘要： A blanking shear machine has a rotatable upper turret having a holder for an upper blade. The upper blade has two contiguous sides which form a right angle therebetween. A rotatably mounted lower turret has a holder for a lower blade which corresponds to the upper blade. Means for clamping and positioning a workpiece are provided between the upper and lower turrets. The turrets are rotated to position the blades to provide the desired cut. A plurality of strikers are provided above the upper turret at four positions above the upper blade at which the contiguous sides of the blade are aligned with the X-axis and Y-axis coordinates. Means for actuating the strikers are provided to lower the upper blade to engage the lower blade, shearing the workpiece between the two blades.

摘要： A method for shearing a plate-like workpiece using a punch press includes providing a punch having two adjacent blades disposed at a specified angle with respect to one another and a die having two blades corresponding to the blades of the punch. The punch and die are adjusted so that one of the blades on one of the punch and die will not mate with the corresponding blade on the other of the punch and die, and the other blade on one of the punch and die will mate with the corresponding blade of the other of the punch and die. The punch and die are brought together to shear the workpiece between the mating, corresponding blades of the punch and die. In one embodiment the blades of the punch are fixed on the base of the punch so as to be fixed with respect to one another. In a second embodiment, the punch is divided into two parts by a sliding surface which bisects the specified angle between the blades of the punch, so that the blades of the punch are longitudinally slidable with respect to one another.
