Abstract
PURPOSE: To efficiently obtain hand tools such as cutting pliers by forming a pair of right and left tool blanks on the front and back of base metal through die forging in such a manner that the main body parts having axial center recesses and grooves and grip parts assume the specific positions and preforming blanking or the like.
CONSTITUTION: After the base metal is heated up to forging temperature, it is formed to a forged plate 3 formed with build-ups of a pair of right and left tool blank 2 shapes on the front and back by forging dies. At this time, an axial hole recess 5 is formed to the center of the build-up part 4a of one side and an axial fitting recessed groove 6 at the axial fitting build-up part 4b on the opposite side, after which a pair of the right and left tool blanks 2 are so positioned that the grip parts 7 are opposed to each other and the main body parts 8 are put on the opposite side. Thence, the tool blank 2 outside shapes are blanked and are machined, if necessary, whereby the finished product 9 is obtained. If working is done with the recess 5 as a reference, it is extremely efficient and the hand tools may be obtained rapidly and inexpensively without waste of materials.
