Abstract
PURPOSE: To manufacture a reinforced spanner from a thin steel plate by cold working specified slots in predetermined position of the head of spanner blank material and forming a swelled out part by broadening the slot.
CONSTITUTION: Using a steel plate III thinner than conventional one, a spanner material II that has a predetermined heat part 5 smaller than the width of a completed spanner I is taken out by stamping. This is roughly worked to form external form of a spanner. Holes 7 are made near the center of predetermined heat parts 5 on both sides of the spanner blank material II. and slots 6 that make angle θ to the center line O and extend to outer periphery are made by cold working. These slots 6 are opened into V-shape by cold working. By this opeing operation, swelled parts that have partially jaw parts on both sides of predetermined head part 5 are formed. Then, by forming fitting groove 3 for bolt, a spanner I of the same strength is obtained using a thin steel plate.
