更可能である。 With reference to FIGS. 3 to 9, 10 is a material,
It has a cylindrical shape with a wall thickness and diameter corresponding to the dimensions of the firing file to be formed, and is a punching residue in the center obtained when cutting a wire rod or a cylindrical firing file by cold forging. You can also use materials. The material 10 is loaded into a die 11 and pressed in the axial direction with a punch 12 to form a concave central portion of the material 10 to form a bar-like projection 13 and an outer link 14. FIGS. 4 to 7 show this process, and the desired shape is formed through several processing steps. At the end of the process, the rod-shaped projection 13 is formed into a mounting shaft of a predetermined shape. In the illustrated embodiment, this process essentially involves leaving the center bar-shaped and indenting the periphery (Fig. 4), deepening the indentation further to extend the outer periphery in the axial direction, and The process of thinning the shaft part (Figs. 5 and 6), deepening the recess to a thickness corresponding to the wall thickness of the pyrotechnic file main body 1, and forming the shaft part into a mounting shaft of a predetermined shape. The process consists of three steps: forming the outer peripheral ring (Fig. 7). However, the number of steps and the molded shape in each step can be changed as necessary.

The material 10 is held by a punch 17 in a die 15 having a die hole 16 with a diameter larger than the diameter of the material 10.
is loaded. A stepped portion 18 having an axial length shorter than the length of the outer ring 14 is formed on the outer peripheral edge of the tip of the punch 17, and is pressed between the punch 17 and a knockout pin 19 having the same shape. Then, the outer circumferential link 14 is bent in the diametrical direction into an inverted U-shape to form the rotation collar 3. dice 15
Knurled lines extending in the axial direction are carved on the inner circumferential surface of the outer link 14, and when the outer circumferential link 14 is bent in the diametrical direction by being pinched by the punch 17 and the knockout pin 19 as described above, the bending occurs. The tip of the section, that is, the top of the U-shape, is pressed against the inner circumferential surface of the die 15, and the knurling lines are transferred to form the knurls 5. Since the knurling lines are carved in the axial direction of the die 15, there is no problem in extruding the material 10 in the axial direction with the knockout pin 19 after forming, and the formation of the knurls 5 is more reliable during extrusion. achieved.

This may be done at the stage of the raw material shown in FIGS. 3 and 10 before molding. Figures 15-17 show the method;
A lower reinforcement jig 20, which has a score 21 on the inner peripheral surface that matches the lower score 2a that is inclined with respect to the axial direction, is loaded into the die 22, and a punch 23 is used to load the material 10 into the lower reinforcement jig 20. (FIG. 15) and pinch it with the knockout pin 24. The material 10 expands in the diameter direction due to the clamping pressure, and the outer circumferential surface is pressed against the inner circumferential surface of the lower crease jig 20, and the creases 21 are transferred (FIG. 16).
After the transfer, the material 10 is rotated with the knockout pin 24 by the lead angle of the lower crease, and the lower crease jig 2 is rotated.
Push out from 0 (Figure 17). By this extrusion, lower lines 2a are formed on the outer peripheral surface of the material 10. The upper score 2b is formed after the molding is completed.

According to this invention, since the rotating collar and the mounting shaft are integrally formed in the file main body, there is no need for processing to fix the collar, which is required in the case of conventional collars that are separated, and manufacturing costs are reduced. It is possible to reduce the Furthermore, since there is no processing such as punching out the material, there is no risk of residual material being generated, and the material can be used effectively. Furthermore, it is possible to easily change the width of the collar, the diameter of the shank or the depth of the recess around the shank on both sides of the firing file for directional selection.
