Abstract
PURPOSE: To easily produce a deformed bolt provided with a screw stem and a rectangular plate by forming a large diameter part and a small diameter part to a wire material, which is blank material, by means of dies and punches, forming a screw engraved part of a small diameter further to the end of the small diameter part and further working the large diameter part to a collar and a head part stem then forging the head part stem to a rectangular shape.
CONSTITUTION: A wire material, which is a blank material, is formed to a large diameter part 32 for forming a collar, and a small diameter part 30 by means of a die and a punch provided with a large diameter hole having a small diameter part and knock-out pin. Next, the engraved part of screw threads 33 is formed to the small diameter part 30 by means of a secondary working die provided with a small diameter hole. Further, the large diameter part 32 is deformed to a continuous shape of the 1st oblique cylinder, middle diameter part, the 2nd oblique cylinder and small diameter part by means of another working punch, whereby a collar 32 is formed. The large diameter part 30 deformed to the middle diameter part, side slope part, etc. is hammered on a working table by leaving the part of the flange 32, whereby a rectangular part 38 is forged. Finally, screw threads 33 are provided to the screw engraving part and holes 39 are opend in the rectangular part 38, whereby the deformed bolt is manufactured.
