Abstract
PURPOSE: To easily form successively the easily breakable parts on the straight outline of the sheet material, by employing the punch provided with a sharp apex in the oblique side.
CONSTITUTION: The polygonal punch 14a, provided with a sharp apex 12 in at least one end of the straight side 11 and the oblique side 13, is employed for forming the easily breakable part by blanking under the condition as follows; the straight side 11 is laid along the straight outline 3 between the blanking points 3a, 3b, in the straight outline 3 of the sheet material, and the apex 12 is placed a little distant from the blanking point 3a, and another end of the straight side 11 is contacted with the blanking point 3b. The punches respectively provided with the apex 12 facing to different direction are selectively employed for forming the blanked parts at desired positions in the straight outlines 3IW3IV mutually crossing perpendicularly. By beating the hedging part with the hammer, respective sheet-metal product is released from the parent metal. According to this method, the breakage, etc., of the material during the blanking work is prevented, and the product still maintaining the parent metal condition can be surely carried away from the punching press machine.
