１のウエブ１９を挟持する。 The apparatus is shown in FIG. A support base 5 having a protruding stopper 4 is attached thereto. 6 is a cam member attached to the other side of the base plate 3 so as to be slidable toward the base plate 3, facing the support base 5; A die 7 facing the die 4 is provided in a protruding manner. 8 is a cushion spring interposed between the back surface of the die 7 and the cam member 6.
Further, reference numeral 9 denotes a connecting protrusion screwed onto the back surface of the cam member 6, and this connecting protrusion 9 is connected to the drive device 11 via the connecting fitting 10. Therefore, the cam member 6 is The drive device 11 causes it to slide toward the stopper 4. Moreover, the die 7 slides together with the cam member 6, and between the cam member 6 and the stopper 4, both flanges 2,
At the same time, the back side of the web 19 of the channel steel 1 is pressed against the stopper 4, thereby causing the web 19 of the channel steel 1 to to hold.

る。 On both upper and lower sides of the stopper 4, which is the outer side of the flanges 2, 2 of the channel steel 1 held in this way, there are punches 12 that can move forward and backward toward the outer surfaces of the flanges 2, 2 of the channel steel 1. , 13 are attached, and by sliding these punches 12, 13 toward the flanges 2, 2 of the channel steel 1 and pressing them against the flanges 2, 2, a first punch is attached to the flanges 2, 2. A drawing process is performed as shown in the figure. Return springs 14, 14 are interposed between the upper and lower punches 12, 13 on both sides of the stopper 4, and bias the punches 12, 13 away from the outer surfaces of the flanges 2, 2. Also, 15 is
This is a presser foot fixed on the support stand 5 to prevent the upper punch 12 from coming off.The right and left sides of the presser foot 15 protrude inward and then further downward to prevent the upper punch 12 from sliding. A guide 18 is formed.

の如く窪ませるものである。 Next, on the opposite side of the flanges 2, 2 of the punches 12, 13, there are inclined surfaces 12a, 13 that are inclined with respect to the advance/retreat direction of the punches 12, 13.
a is formed, and these inclined surfaces 12a, 13a
are inclined in opposite directions. On the other hand, the cam member 6 disposed on the sides of both punches 12 and 13 is provided with a pair of cam-shaped protrusions 16 and 17 that protrude toward the punches 12 and 13. , 17, the punch 12,
A pair of inclined surfaces 16c and 17a are formed which are inclined in the same direction as the thirteen inclined surfaces 12a and 13a. Therefore, the cam member 6 is
When the cam member 6 is advanced in a direction perpendicular to the advancing and retracting direction and toward the punches 12 and 13, the inclined surfaces 16a and 17a of the cam member 6 move against the punches 12 and 13.
Both punches 12, 1 slide along the inclined surfaces 12a, 13a of 13, and due to the cam action
3 to the stopper 4, that is, the flanges 2, 2 side of the channel steel 1, and press it against the flanges 2, 2, thereby making both the flanges 2, 2 depressed as shown in Fig. 1. It is something.
