THERE IS PROVIDED A TAB TERMINAL MANUFACTURING APPARATUS THAT CAN MANUFACTURE A TAB TERMINAL, IN WHICH THERE IS NO BURR IN A FLATLY PRESSED PART OF AN ALUMINUM HEAD AND THE FLATLY PRESSED PART HAS A UNIFORM THICKNESS AND HAS FOUR CORNERS IN A ROUNDED FORM. THE TAB TERMINAL MANUFACTURING APPARATUS INCLUDES A CUTTING BLADE (13) FOR PARTIAL CUTTING AND A CUTTING BLADE (14) FOR CUTTING-OFF. A PUNCH (3) FOR PRESSING AN ALUMINUM HEAD FLAT (B) IS BUTTED AGAINST THE ALUMINUM HEAD AND SQUASHES THE ALUMINUM HEAD FLAT (B) TO GIVE A PREDETERMINED ALUMINUM HEAD THICKNESS. AT THAT TIME, A PART OF THE ALUMINUM HEAD (B) IS FORCED OUT FROM THE PUNCH (3). THE CUTTING BLADE (13) FOR PARTIAL CUTTING IS MOVED IN A GOING DIRECTION, PARTIALLY CUTS THE FORCED-OUT PORTION OF THE PRESSED ALUMINUM HEAD (B) TO FORM A CUTTING LINE IN THE FORCED-OUT PORTION, AND IS THEN REVERSED IN ITS MOVING DIRECTION TO BE MOVED IN A RETURNING DIRECTION. THE CUTTING BLADE (14) FOR CUTTING-OFF IS MOVED IN A DIRECTION OPPOSITE TO THE GOING DIRECTION OF THE CUTTING BLADE (13) FOR PARTIAL CUTTING TO CUT OFF THE FORCED-OUT PORTION OF THE ALUMINUM HEAD (B) ALONG THE CUTTING LINE. THE CUTTING BLADE (13) FOR PARTIAL CUTTING HAS A NOTCH (P) IN ITS EDGE PORTION. |
