Abstract

PURPOSE:To cut burrs at the same time as to straighten strain and bond of a work by providing a dedicated deburring broach blade operating in synchronization with the layer relative monitor of deburring dies to press-in dies to blank a work into a die. CONSTITUTION:The work is set on a deburring lower die 19, a main pressurizing cylinder 10 is lowered and halts temporarily as the work is held lightly by a press-down upper die 14. Burrs on the side are cut by side broache cutting edge 17 through the advance of a side cylinder 12, then, the broaches, etc., return to the initial positions. The lower cylinder 11 is elevated, the broach blades 8, 9 pass through the broach guide groove of the lower die 19 for burring and project upward, cut the burrs at the weir part and the shadow part of the projecting part of the work, then, return to the initial positions. The main pressurizing cylinder 10 is lowered again, the work is pressed down by the press-down upper die 14 and blanked by the cutting blades on the outer peripheral edge part of the lower die 19, the corner burrs are cut, then, the cutting blades return to the initial positions. The work is discharged outward through a shoot 21.
