[Embodiment] An embodiment of the fabric punching die structure of the present invention will be described below with reference to FIGS. 1 to 4. In these figures, the same components as those of the conventional components shown in FIGS. 5 to 8 are designated by the same reference numerals and the description thereof will be omitted.

The cloth punching die structure shown in FIGS.
The difference from the ones shown in FIGS.
In addition, the inner diameter stripper (stripper) 3 is held so as to be movable downward, flush with the die 2 or slightly lower than the die 2 against the biasing force of the coil spring (spring member). The point is that an elevating mechanism 20 is provided for elevating the inner diameter stripper 3 so as to project from the die 2 when separating.

That is, a cylinder portion 21 is formed on the fixed base 1, and a piston portion 22 is provided on the cylinder portion 21 so as to be vertically movable. A flange portion (first flange portion) 22a protruding in the radial direction is formed on the upper end portion of the piston portion 22. On the other hand, the inner diameter stripper 3 is formed with a hole portion 23 into which the flange portion 22a of the piston portion 22 is vertically slidably fitted. A flange portion (second flange portion) 23a protruding inward is formed on the peripheral edge portion of the opening of the hole portion 23, and the flange portion 22a has the flange 22a.
By engaging with, the piston portion 22 is prevented from being pulled out from the hole portion 23.

The length of the piston portion 22 is such that when the piston portion 22 is located at the lowest point, the flange portion 22a of the piston portion 22 is
And the flange portion 22a of the hole 23 are pressed against each other by the coil spring 4 so that the upper surface of the inner diameter stripper 3 is flush with the upper surface of the die 2 and the piston portion 22 is located at the uppermost point. The upper surface of the inner diameter stripper 3 is set to project from the upper surface of the die 2.

Further, the hole portion 23 of the inner diameter stripper 3 is formed to a depth such that a clearance is generated between the tip end surface of the piston portion 22 and the upper surface of the hole portion 23 when the piston portion 22 is located at the lowest point. However, this clearance is set to be slightly longer than the length by which the inner diameter stripper 3 is pressed by the punch 8 and moves downward when the cloth piece 6 is punched from the cloth body 6 by the punch 8.

Next, the operation of the fabric punching die structure having the above-described configuration will be described.

As shown in FIG. 1, when the piston portion 22 is retracted to the lowermost point, the inner diameter stripper 3 is moved downward against the biasing force of the coil spring 4 so that it is flush with the upper surface of the die 2. Become. Then, as shown in FIG.
The movable table 5 is lowered and the outer diameter strippers 10 and 10 press the fabric body 6 against the upper surface of the die 2 to restrain it.
As shown in the figure, the movable table 5 is lowered to punch the cloth piece 7 from the cloth body 6 with the punch 8. At this time, the inner diameter stripper 3 is pressed from above by the punch 8 and moves downward.

Thereafter, as shown in FIG. 4, the movable table 5 is raised while keeping the outer diameter stripper 10 restraining the cloth body 6 to raise the punch 8 and the piston portion 22 to the highest point. . Then, the inner diameter stripper 3 protrudes from the upper surface of the die 2 to tear off the thread connecting the cloth body 6 and the cloth piece 7 to completely separate them.

Next, as shown in FIG. 1, the movable table 5 is further raised to separate the outer diameter stripper 10 from the cloth body 6, and the piston portion 22 is lowered to the lowest point, so that the upper surface of the inner diameter stripper 3 is moved to the die 2 Be flush with the top surface of. Then, when the cloth body 6 is pulled to the right in this state, since the inner diameter stripper 3 does not project from the die 2, the cloth body 6 is smoothly fed without being caught by the inner diameter stripper 3.

Thus, according to the fabric punching die structure having the above-mentioned configuration,
An elevating mechanism 20 for elevating the inner diameter stripper 3 inside the die 2 is provided on the fixed base 1, a cloth piece 7 is punched from the cloth body 6 by the punch 8, and the inner diameter stripper 3 of the die 2 is moved by the piston portion 22 of the elevating mechanism 20. After the threads that connect the cloth body 6 and the cloth piece 7 are peeled off by completely protruding them from the upper surface, the piston portion 22 is lowered to the lowest point, and the upper surface of the inner diameter stripper 3 is die-cut. Since the cloth 6 is held flush with the upper surface of the cloth 2, the inner diameter stripper 3 does not protrude from the die 2 when the cloth 6 is fed, so that the cloth 6 does not get caught on the inner diameter stripper 3 smoothly. Since the feeding is performed, it is possible to eliminate the problem caused by the conventional cloth body 6 being caught by the inner diameter stripper 3.

[Advantage of Invention] Since the present invention is configured as described above, the stripper does not protrude from the die during feeding of the fabric body after the fabric body is punched out, so that the fabric body is Since it smoothly feeds without getting caught in the stripper, it is possible to solve the problem that the conventional work is obstructed by punching work and wrinkles of the fabric caused by being caught by the stripper. .

Further, since the lifting mechanism is provided across the fixed base and the stripper, that is, the lifting mechanism is provided inside the fixed base, the fabric punching die as a whole is compact, and the lifting mechanism is driven. However, since a piston-cylinder system with a long life is adopted without using a motor, the cost is not increased and maintenance inspection is easy.
