ンボルト成形装置。[Scope of Claim for Utility Model Registration] 1. The process of cutting the steel inner bar material into predetermined dimensions, and swaging the cut material and reducing the shaft portion to the required diameter d1 , leaving a portion that will become the head. The ampulla heading process is performed in a tension bolt heading machine which comprises a preliminary process and an ampulla heading process of forging an ampulla with an outer diameter d 2 larger than the shaft diameter d 1 at the tip of the shaft after forming the head. The device used for this purpose includes: (1) a die block 11 that is supported elastically within the die case 10 and moves forward and backward, and has a conical opening 11a that widens forward at the front end; (2) further pressure is applied to the die block; A mold hole 12 of the same shape for molding the ampullae
(3) A die member 12 having a diameter of a, (3) is fitted into the conical opening 11a of the die block 11 in a state where the die member 12 is abutted immediately before the die member 12, and when the punch is driven, the diameter of the die member 12 is reduced as it is pushed toward the die member side, and the material is (4) A conical split die 13 consisting of a split member that operates to grip the shaft of the die member 12 and the split die 13; (5) A center support rod 14 having a protrusion 14a that fits into the center hole of the end face of the enlarged part of the material and holds the material in a suspended form; A tension bolt forming apparatus in a multi-stage former, characterized in that a punch member 20 is provided with a center pin 21 that elastically moves in and out so as to hold a recess 20a for holding the parts together. 2. The above-mentioned utility model registration in which the die member 2 in the ampulla pre-heading step is provided with a support rod 4 having a pointed protrusion 4a that supports so as to form a center hole in the end face of the ampulla by punching during pre-heading of the ampulla. A tension bolt forming apparatus in a multi-stage former according to claim 1. 3. Projection 14a at the tip of the center support rod 14
2. The tension bolt forming device for a multi-stage former according to claim 1, wherein said utility model is a conical pointed protrusion.
