The conventional method of forming a locking head on the end of a reinforcement is to grasp the vicinity of the end of the reinforcement with a chuck attached to the equipment frame of the upsetter, and then position the end laterally. The header of the reinforcing cylinder is pushed toward the end, and electricity is applied to the vicinity of the head of the reinforcing material through the header and chuck, and the end heated by resistance heat is upset and forged. A locking head is formed between the end and the side end of the chuck, and the size of the locking head is determined according to the wire diameter of the reinforcing material. Depending on the locking head to be used, the mounting position of the header attached to the upsetting piston of the upsetting cylinder can be adjusted in and out by rotating the adjustment nut, and the chuck can be adjusted in the state before upsetting. The distance between the end of the pushing head and the side end of the bar is adjusted to a predetermined value to correspond to the wire diameter of the reinforcement.

Since this invention is as described in detail in the above-mentioned embodiment, the locking head d, which should be formed according to the diameter of the reinforcement M, is formed at the tip protrusion m of the chuck C. The tip protrusion m is determined by the distance between the end face of the chuck C and the position of the header 10 before approaching for the transfer operation. Therefore, the distance n between the end face of the chuck pieces 5, 7 and the guide pin holes 12, 12 is set in advance according to the diameter of each reinforcing material M. By selecting 7 and fixing it to each mounting side, the chuck C can be mounted extremely easily and quickly, and the troublesome work of adjusting the mounting position of the header 10, which is conventional, can be omitted. In addition to improving workability, the chuck pieces 5 and 7 can be interchanged with each other, and the service life of the chuck pieces 5 and 7 can be greatly extended and improved, contributing to cost reduction.
