Abstract

PURPOSE:To work a notch groove of a pipe material having a smooth surface or a solid rod material, in a short time by a press, by moving two pieces of punches by a cam-shaped side wall of the inside of an upper die by an ascent of the upper die, and cutting the notch groove on an object to be worked. CONSTITUTION:An object 10 to be worked in inserted into a placing hole 7b of a punch holder and an upper die is made to descend by operating a press machine. Rollers 6a, 6b of the end face of a punch run along cam surfaces 2a, 2b of the upper die and punches 4, 5 pinch and attach an upper end 11a of the object 10 to be worked. Also, the upper die 1 descends and the rollers 6a, 6b run along the side wall and move forward to the center of the punch holder by being guided by a punch holder 7a, and cut the object to be worked. The upper die 1 further descends, the rollers 6a, 6b move along the side wall, the punches 4 and 5 move in the left direction and a notch groove is cut completely. When the cutting is completed and the upper die 1 ascends, the punches are opened mutually by a spring and reset to the original position.

(Problems to be Solved by the Invention) However, in the milling process, cutting takes time, and when machining stopper grooves for automobile parts, the time becomes unbalanced with other machining times, and the groove machining takes too much time. Also, during shaving, it is difficult to obtain a smooth sheared surface over the entire surface because the sheared layer is uneven.
Another problem is that the life of the punch is short due to problems such as punch welding and breakage of the punch tip.

(Means to solve the problem) The technical measures taken to solve the above technical problem are:
It looks like this: That is, in a mold consisting of an upper mold and a lower mold of a press, a cam-shaped side wall is provided to move a punch inside the upper mold to the right or left, and the punch having a roller at the end is guided by a punch holder. In a mold that is moved to the right or left from the hole and the punch holder is fixed to the lower mold, a hollow pipe or solid round bar is placed on the punch holder, and the upper mold is lowered to form a notch groove. It's a method.

(Operation) The above technical means operates as follows. That is, the upper die is lowered and the cam-shaped side wall contacts the roller at the end of the punch, and the two punches held in the punch holder compress the springs and slide through the guide holes of the punch holder one after another. The tip of the punch touches a part of the upper side of the bar held at a fixed position in the punch holder, and as the upper mold descends, the punch advances and cuts a part of the bar. , when the upper die further descends, the cam-shaped side wall inside the upper die
The notch is completely cut by moving the punch to the left or right side with the material held in place a distance approximately equivalent to the diameter of the bar.
