ずれたりしないようにしている。 Reference numeral 15 denotes a presser foot, which is attached to the presser foot 14 via a compression spring 16, and as the presser foot 14 moves downward, the steel bar R is moved onto the supporter base 14.
This prevents the steel bar R from rotating or shifting laterally during cutting.
次に、上記実施例装置よる補強筋の製造方法に
ついて説明する。 Next, a method for manufacturing reinforcing bars using the apparatus of the above embodiment will be explained.
まず加工すべき棒鋼材Ｒを第１図に示すように
支持台４と押え台１５の間に挟んだ状態でセツト
し、ダボを形成させたい箇所を上下の切断刃３，
１３の間に位置させる。 First, the steel bar R to be processed is set between the support stand 4 and the presser stand 15 as shown in Fig. 1, and the upper and lower cutting blades 3,
It is located between 13 and 13.

側面は下側切断刃３の尖端部３ｂに突き当たり、
棒鋼材Ｒは上下の切断刃３，１３の尖端部３ｂ，
１３ｂに挟まれた状態になる。 Next, when the press base 14 is pushed down, the upper cutting blade 13 is lowered and its pointed end 13b is lowered.
hits the upper side of the steel bar R and pushes the steel bar R down a little. When the steel bar R is pushed down, its lower surface hits the tip 3b of the lower cutting blade 3,
The steel bar R has the pointed ends 3b of the upper and lower cutting blades 3, 13,
13b.

される。第６図から明らかなようにこの状態では
支持台４はベース板２に当設し、また押え台１５
も押圧台１４に当接している。 When the press base 14, that is, the upper cutting blade 13 is further pushed down in this state, the pointed ends 3b, 13b bite into the steel bar R. (See FIG. 5 and FIG. 5A) Meanwhile, while the upper cutting blade 13 is being pressed down,
The presser foot 15 presses the steel bar R downward via the compression spring 16, and the support base 4 supporting the steel bar R is configured to be elastically retractable by the elastic member 10. As the upper cutting blade 13 is pushed down, the entire bar R also descends. (5th
(See figure) When the pressing base 14, that is, the upper cutting blade 13 is pressed down with the pointed ends 3b and 13b biting in, the upper and lower cutting blades 13 work to generate a shearing force along the central longitudinal section r of the steel bar R. As a result, the steel bar R is divided as shown in FIGS. 6 and 6A, and the divided portion is pushed outward by the upper and lower cutting blades 3 and 13, resulting in a dowel D that protrudes upward and downward. It is formed. As is clear from FIG. 6, in this state, the support stand 4 is in contact with the base plate 2, and the presser stand 15 is in contact with the base plate 2.
is also in contact with the press base 14.
尚、押圧台１４の押圧力を解くと、弾性材１０
の反発力により支持台４が上方へ復帰して棒鋼材
Ｒを押し上げ作業を終了する。 Note that when the pressing force of the pressing table 14 is released, the elastic material 10
The support platform 4 returns upward due to the repulsive force of , pushes up the steel bar R, and ends the work.
上記実施例の装置は、下側切断刃１３が下降す

性的に押え付けるように構成してあるが、押え台
１５は押圧台１４に固定して設けても良い。 In the device of the above embodiment, the lower cutting blade 13 is lowered, but it is also possible to raise the lower cutting blade 3 or to move the upper and lower cutting blades 3 and 13 up and down at the same time. . Furthermore, the above embodiment device has the following features:
The presser stand 15 is attached to the presser stand 14 via a compression spring 16 to elastically press down the steel bar R set on the supporter stand 4, but the presser stand 15 is fixed to the presser stand 14. It may also be provided.
尚、上下の切断刃３，１３にはその中央部に尖
端部３ｂ，１３ｂを形成してあるが、該尖端部３
ｂ，１３ｂの位置は左右にずらせても良く、また
複数個設けても良い。 Incidentally, the upper and lower cutting blades 3 and 13 are formed with pointed portions 3b and 13b at their central portions;
The positions of b and 13b may be shifted left and right, or a plurality of them may be provided.
また、一方の切断刃に尖端部を形成せず、その
尖端面を平面に形成しておくと、ダボＤが一方向
にのみ形成される。 Furthermore, if one of the cutting blades does not have a pointed end and its pointed end surface is formed into a flat surface, the dowel D will be formed only in one direction.
