Description of the Related Art Today's punching metal is used as a ceiling material, a decorative handrail, a signboard, a certifying device, an exterior, etc. for interior and exterior construction, and various soundproofing / sound absorbing devices for sound / sound insulation / heat insulation, vehicles, railways, aircrafts, etc. Soundproofing equipment, etc., interior / exterior parts, radiator grills, air filters, etc. for automobiles, and acoustic equipment grills, mechanical covers, wall panels for air conditioning, etc. as various ventilation / sound-passing covers. -It is used in various fields such as strainers, templates for sorting and cleaning, various shelves and trays, corridors and floor materials, various screens, kitchens, partitions and separations. When a punching metal of this kind is conventionally manufactured, the metal plate material 3 is punched by a female die 1 having a punched hole 5 formed in a required shape and a male die 2 corresponding to the female die 1. However, when the metal plate material 3 is punched, the periphery of the hole is sagged downward by the punch pressure of the male die 1,
A so-called burr 4 that points downward is formed. Female type 1
The periphery of the hole on the top surface gradually wears out, resulting in inaccurate and uneven punched hole shapes, resulting in poor quality punching metal and increasing the amount of burrs 4 sagging. There is the complexity of having to do it. Punching metal is used for various purposes as described above, but depending on the purpose, it may be necessary to completely remove burrs, or there is a place where it is necessary to remove burrs only partially. For this reason, conventionally, as a means for removing burrs, a means has been adopted in which burrs are scraped off only at necessary portions or on the entire surface with a brush, a rotary grindstone, a grinder, or a zircon.

る。SUMMARY OF THE INVENTION The problem to be solved by the present invention is that, in the conventional punching metal manufacturing apparatus, a burr is always generated in the punching direction of the hole of the punching metal, and this burr causes the punching metal to be a building material or the like. There is a problem that it has to be scraped off because it will inevitably interfere depending on the purpose of use or the location of use, so it is necessary to prevent this burr from occurring in the manufacturing process of punching metal, that is, punching without burr. When manufacturing metal, further, in the conventional manufacturing equipment, the upper surface of the female mold is polished because the upper surface of the female mold becomes worn and the peripheral portion of the punching hole becomes worn, and it becomes impossible to accurately punch the punched hole of the required shape. There was the complexity of having to do it. From the above viewpoints, the present invention is to provide a burr-free punching metal manufacturing apparatus that prevents burr generation in the manufacturing process of punching metal and does not require the entire surface of the female die to be polished.

It is configured so that a proper gap 18 is formed between the gap 9 and 9. Next, the upper die stripper 10 is a scraper to be placed on the metal plate material 17, but punch holes 6, 6 are provided at positions corresponding to the punch holes 6 of the female die 7, that is, the punch holes 6'of the female punch sesame 11. It is a plate material having an appropriate thickness and having at least the same size punch hole 6 ″ as that of the ′ ′. Next, the male die 8 is formed into the punch hole 6 (and hence the punch holes 6 ′ and 6 ″). It goes without saying that the punch 21 is formed so as to project at the corresponding position. As described above, this device is
Female punch sesame fitting portion 12 is formed on the upper portion thereof at the same position as the punch hole 6 and the punch hole 6 ′ is formed in the fitting portion 12.
And a female punch sesame 11 having a deburring point 19 formed therein are slidably mounted, a spring 15 is placed in a spring holding hole 16, and a lower die stripper 9 is placed on the female die 7 via the spring 15. The apparatus is characterized in that the metal plate material 17 is placed on the stripper 9 and the upper die stripper 10 is further placed thereon so that the punch 21 of the male die 8 can punch the metal plate material 17.

２との間に適宜調整スペ−サ−を使用する。When the metal plate material 17 is punched out, a punch 21 is formed around the hole formed on the surface of the metal plate material 17.
Since the punching pressure is applied downward, it is slightly inclined downward, and the lower peripheral portion of the hole formed in the metal plate material causes a downward sag burr 4 due to the punch pressure in the conventional apparatus. Since the tip of the female punch sesame 11 is formed on the deburring point 19 and is inclined toward the outer peripheral surface of the punch sesame, the metal plate material 17 is lowered to some extent by the punching pressure and the weight of the upper die stripper 10. The generated burr 4 is scraped off by the tip 19, and the cut surface is formed as a surface having an angle corresponding to the inclined polishing angle of the deburring tip 19 to some extent. After punching, the lower die stripper 9 and the metal plate 17 and the upper die stripper 10 are lifted by the force of the spring 15 and returned to their original positions. A burr-free punching metal can be manufactured by continuously performing the above punching work. Since the height of the female punch sesame 11 is gradually lowered by polishing the deburring point 19 during use, the sesame 11 and the female punch sesame holder 2 are not shown.
A suitable adjusting spacer is used between the two.

使用することができるという利点もある。The punching metal according to the present invention has the effect that burrs are scraped off by the action of the female punch sesame in the manufacturing process thereof, so that it is easy to produce a so-called punching metal without burrs. There is an advantage that it can be used regardless of the front and back of the metal when using it. In the past, however, there were places where there was absolutely no burr depending on the place of use, and that part was deburred with a brush, rotary grindstone or grinder or geranium, but in the case of the present invention the entire surface was deburred. Since it is a burr-free punching metal, it has the advantage that deburring work is not required and the construction is extremely efficient. Further, conventionally, there is a drawback that the periphery of the punch hole on the surface of the female die 1 becomes rounded and the shape of the die-cutting hole becomes inaccurate, so that the burr 4 gradually becomes large. Therefore, the entire surface of the female die 1 is polished for a while. However, in the present invention, it suffices to polish only the deburring point of the female punch sesame 11 in the present invention.
It also has the effect that it is not necessary to polish the entire female mold. After using it for a long time, deburring cusp 19
When the height of the female punch sesame 11 becomes low due to polishing, the adjustment spacer may be used between the female punch sesame receiver 22 of the female punch sesame fitting portion 12 and the female punch sesame 11. Has the advantage that it can be used for a long time without replacement.
