Abstract

PURPOSE: To manufacture the anchor bar at a low price by cold processing, by providing two steps upsetting part formed at the one end of deformed bar on tapered part of support apparatus and carrying out compression deformation of the upsetting part in two steps.
CONSTITUTION: The upsetting part 9 composed of the perfect circle large diameter part 9a and small diameter part 9b, is formed by rolling so as to be contracted the above part at the one end side of the deformed bar 2 cut in a required size. Next, the bar 2 is put in the support apparatus 14 providing the tapered part outer die 17 on the one tip end after heightning the rectilinear property of the bar 2 by publicly known aparatus, if necessary, the part 9 is arranged at the part 17. Then, the part 9b is inserted into the sliding hole 20 of the beating apparatus 18 and is made not to deform and then, compression deformation of the part 9a only is carried out striking the part 9b by the piston 19 of the apparatus 18 strongly. Next, the heading device 22 is connected with the apparatus 18 and the part 9b is deformed to expand by pressing the heading pin 23 against the center of tip face of the part 9b and then, tapered part is formed plugging the part 17 with the part 9.
