To this end, the lifting means 440 may include a lifting cam 441 , a swing lever 442 , a transfer roller 443 , and a lifting bar 444 .

The lifting cam 441 is a pair of cams that are coupled to be spaced apart from the camshaft 200 and rotate together with the camshaft 200 .

And a swing lever 442 is horizontally provided so as to be adjacent to one side of each of the lifting cams 441 . Each of the swing levers 442 is hinged at the center so as to be swingable up and down. In other words, it works like a seesaw.

In addition, the primary molding die 540 is horizontally arranged on the lower side of the primary molding press 530 , that is, on one side of the transfer chain 430 .

The primary forming die 540 is formed with a triangular prism groove 541 in the shape of a 'V' groove having an isosceles triangular cross section on the upper surface as shown.

Therefore, when the primary molding press 530 descends and presses in a state where the material n is located in the triangular column groove 541, the end of the material n becomes a triangular prism shape having an isosceles triangle in cross section.

Next, the secondary pressing unit will be described with reference to FIG. 6 together. 6 is a side view showing the secondary pressing unit of the present invention shown in FIG.

The secondary pressing unit 600 is for secondary processing of the end of the material, the crankshaft 610, the secondary forming rod 620, the secondary forming press 630, the secondary forming die 640. It can be implemented including

As shown in the figure, the secondary forming die 640 has a triangular pyramidal groove 641 having a triangular pyramid shape on its upper surface.

Accordingly, when the secondary forming press 630 descends and presses the material n having a triangular prism shape through the primary processing in the triangular pyramid groove 641, the end of the material becomes a triangular pyramid shape and a sharp needle The ends are molded, and burrs are formed at both ends. These burrs can be removed later by grinding.

It is drawn in and mounted in the material groove 381 located on one side of the supply wheel 380 intermittently rotating one by one from the material n located at the bottom of the input and stacked material.

As the supply wheel 380 rotates intermittently, the material n mounted on the material groove 381 is rotated.

When the mounted material n rotates and reaches the other side of the supply wheel 380 , the transfer chain 430 of the material transfer unit 400 receives the material n as shown in FIG. 8A .

At the same time, the transfer chain 430 moves forward to position the material at the next pitch.

Of course, at this time, since the primary molding press of the primary pressing unit 500 and the secondary molding press of the secondary pressing unit 600 rise, they do not collide with the material.

When the material is transferred, the lifting means 440 lowers the support frame 100 again, and the next material n is seated on the primary forming die 540 and the secondary forming die 640, respectively. The primary pressing unit 500 and the secondary pressing unit 600 perform molding at the same time.
