Field of the Invention The present invention relates to a device for removing punching scraps in a paper punching device, and more specifically, it inserts a pre-punched material sheet between a pair of upper and lower dies and projects it from one die. The present invention relates to a device for punching out a punching line of a material sheet with the projections and removing the punching scraps.

In the previous step, for example, as shown in FIG. 17, the punching line L around the punching product 2 which is a finished product is cut from the material sheet 1 on which the punching line L is formed by performing the required punching.
Various devices are provided for removing the punching scraps 3 partitioned by. As shown in FIG. 18, the punching line L that is die-cut in the above-described pre-process has a so-called perforation shape, and a seam (hereinafter, referred to as a residual portion 4) is formed at a cut portion with a required interval. It is formed in the state where it remains.

外脱させている。As an external device for removing the die-cut material sheet 1, for example, a device shown in FIGS. 19A and 19B is conventionally provided. In the apparatus, the substrate 6 of the upper mold 5
In addition, the punching material 7 is projected downward along the outside with a slight gap from the punching line L, while the lower die 8 holds the substrate 9 having a size slightly smaller than the outer shape of the punched product. Then, the upper die 5 is lowered, and the punching scraps 3 are pushed down by the projections 7 so that the residual portion 4 is separated and the punching scraps 3 are released.

め、上記したように、打抜材７は打抜ラインＬより隙間
をあけて配置している。As described above, in the external removal device, the surface of the portion which becomes the punching scrap 3 is pushed downward by the punching material 7 and the material sheet 1 is bent along the punching line L. The residual part 4 connected to the part of the product 2 supported by the substrate 9 is, so to speak, cut apart. As described above, when the punching-out material 7 is bent to separate the portion that becomes the punching dust 3 by the punching-out material 7 during the external action, the punching-out material 7 is positioned just above the punching line L. Since it is preferable to position it slightly outward, the punching material 7 is arranged with a gap from the punching line L as described above.

がスムーズに折り曲げられない場合が生じる。When the width W1 of the punching waste 3 is wide, it is necessary to apply a large load to separate the residual portion 4 to surely remove the punching waste 3, but the conventional punching material 7 Since the width W1 of the punching waste 3 is wide and the thickness of the punching material 7 is thin in comparison with that, since the vertical width is uniform, the load is applied only to the portion along the punching line. A sufficient load cannot be applied at a position distant from the punching line, and therefore the punching scrap 3
May not be bent smoothly.

せず、残留部４での切り離しがより困難となっている。On the contrary, when the width W1 of the punching waste 3 is small, a large load cannot be applied to the punching material 7 and the residual portion 4 may not be cut off. That is, the external removal device makes it easy to bend the punching scrap 3 along the punching line L and prevents the punching material 7 from colliding with the substrate 9 of the lower die 8, as described above. The outer edge of is punched out from the punching line L and released to the inside. Therefore, the portion of the punching scrap 3 refracted by the punching material 7 easily enters the inner gap and is inclined toward the substrate 9 side. Thus, when inclined, the contact area with the punching material 7 decreases,
The load of the punching material 7 does not sufficiently act on the portion that becomes the punching scrap 3, and the separation at the residual portion 4 becomes more difficult.

た外脱装置を提供している。In order to solve the above-mentioned problems, the applicant of the present invention previously disclosed in Japanese Patent Application No. 5-82149 that a first punching portion and a second punching portion were formed in a punching material with a step formed therebetween. A material is provided, and the first punching portion is arranged outside with a required gap from the punching line, contacts the surface of the punching dust and presses it, and refracts the punching dust with the residual portion as a fulcrum. , The second punching section is disposed closer to the punching line than the first punching section, is retracted from the first punching section, is bent by the first punching section, and is bent by the first punching section to be displaced in the horizontal direction from the vertical direction. Provided is an external removal device configured to be brought into contact with and to be pushed down.
【０００８】上記のように打抜材を改良した場合にも、

題が残っている。Even when the punching material is improved as described above,
When the load of the first punching portion that first contacts the punching scrap is small, there remains a problem that the punching scrap cannot be smoothly bent.

In the punching material 13 of the example, a step portion 28 protruding toward the punching line L is formed on the vertical axis portion 25 at a position above the lower end by a predetermined dimension, and a cross section V is formed on the lower surface of the step portion 28. A convex portion 29 having a V shape is formed. The width W2 of the stepped portion 28 is such that when the cut portion 19 or the residual portion 20 of the material sheet 10 is bent and the cut surfaces 19a, 20a are displaced upward in the horizontal direction,
The projection 29 is in contact with the cut surfaces 19a and 20a, and the lower side surface of the horizontal shaft portion 26 is set to have a size in contact with the surface of the punching scrap 17 outside the punching line L. Therefore, the step 28
The width W2 becomes large when the thickness T of the material sheet 10 is large, and becomes small when the thickness T is small and the material sheet 10 is thin.

At this time, since the convex portion 29 has a V-shaped cross section, the cut surfaces 20a and 19a are easily locked, and are hard to come off after being locked. the above
In the state shown in (D), by further lowering the convex portion 29, the cut surfaces 20a, 19a are pushed down by the convex portion 29, and as shown in (E), the residual portion 20 is surely pushed off and punched. The product 18 and the punching waste 17 can be separated. During the operation from (D) to (E), the bent punching dust 17 is sandwiched between the projecting portion 33 and the pressing portion 31 and is held substantially vertically without tilting. Cutting surface 20
A and 19a are pushed down by the convex portion 29, and as a result, the residual portion 20 can be reliably cut off.

に外脱できる。Further, when the horizontal shaft portion is projected at the tip of the vertical axis portion and the outer surface of the horizontal shaft portion serves as the contact surface, and the contact surface is large, the punching material is brought into contact with the punch dust. When the width is wide, a large pressing force can be applied to the punching waste without increasing the weight of the punching material, and in particular, the wide punching waste can be reliably released.

ることが出来る。On the other hand, when the width of the punching waste is narrow, if a punching material having a stepped portion on the vertical axis is used, it is bent by the pressing portion to expose the cut surface in the horizontal direction and then this cutting is performed. Since the stepped portion is brought into contact with the surface and pushed down, the residual portion can be reliably cut off, and the punching waste can be separated from the punched product and released.
