Abstract

PURPOSE:To improve the efficiency of a blanking work by forming a projecting part on an opposite feed side from a blanking part of a stock at the time of blanking of a product, engaging the blanked product by the projecting part and transferring it simultaneously with the stock. CONSTITUTION:On the upper die 27 of a compound die, an upper die stripper 32 with a spring 31 is provided, and also, in addition to a die hole 29a, two pieces of louvering die holes 29b are installed. On the lower die 28, two pieces of louvering punches 36 are provided. In this state, a hoop material 23 is fed in, a blanking plate 37 is blanked, and also, simultaneously a projecting piece 38 is formed in the hoop material 23 in cooperation with the punch 36 and the die hole 29b. When the lower die 28 ascends, the blanking plate 37 is drawn out of the hole 29a, and in this state, when the hoop material 23 is fed, the blanking plate 37 is also caught by the projecting piece 38 and transferred to the outside of a press. Since an adjusting work for returning the blanking plate 37 to the hole becomes unnecessary, the efficiency of blanking work is improved.

When the hoop material 23 is fed one pitch in the direction of arrow A by a feeding device (not shown), the ram of the press machine is lowered. As a result, the upper die stripper 31 presses and fixes the hoop 23 onto the lower die punch 33 and the lower die stripper 35 by the spring force of the compression coil spring 32. In this state, the punching die hole 29a of the upper die 29 and the lower die punch 33 work together to punch out the rotor core punching plate 37, and the die hole 33a of the inner diameter punch 30 and the lower die punch 33 are punched out. A center hole 37a is punched out in the punching plate 37 by the cooperative action of the two.

When the punching plate 37 is punched out in this manner and the protruding piece 38 is cut and raised in the hoop material 23, the upper die 27 is raised. As a result, the hoop +A23 is pulled out from the lower die punch 33 by the lower die stripper 35, and the punching plate 37 is removed from the punching die hole 2 by the upper die stripper 32.
Extracted from 9a. At this time, the spring force of the compression coil spring 31 of the upper mold stripper 32 is applied to the punching die hole 29
Since the punching plate 37 can be pulled out from a,
The punched groove 37 is almost never press-fitted into the hole 39 created in the hoop material 23 by punching out the punched groove 37,
It is simply placed on the hoop material 23.

In this state, the hoop material 23 is fed one pitch in the direction of arrow A in order to punch out the next punched board. The hoop material 23 is latched, that is, hooked, and transported together with the hoop material 23, and then transported to the outside of the press machine 21. Then, the punched board 37 transferred to the outside of the press machine 21 together with the hoop material 23 is transferred to the chute 24 by the hoop material 23 entering the lower side of the chute 24, and slides down the chute 24 into the stock case 25. Stocked. Incidentally, in order to prevent the protruding piece 38 from adversely affecting the dimensional accuracy of the wiping material 37, it is preferable to form the protruding piece 38 at a position approximately 5 mm apart from the hole 39. In order to securely lock and transport the punching board 37, as shown in FIG. It is preferable to provide the Further, by crushing the protruding piece 38 after transferring the punching plate 37, the hoop material 23 can be inserted below the chute 24 without the protruding piece 38 getting caught on the chute 24.

As described above, according to the present embodiment, the punching plate 37 can be transported by the protruding piece 38 formed on the hoop material 23 as the hoop material 23 is fed. Therefore, the punched plate 37 can be transferred without any trouble without being press-fitted into the hole 39 of the hoop material 23. Therefore, in order to press-fit the blanked plate 37 into the hole 39 by about half the thickness of the plate, both compression coil springs 31 And the spring force of 34 is 1=l! There is no need to go through the troublesome task of writing one verse.
