There is an inconvenience that 2 is destroyed. In order to solve this problem, as shown in FIG. 5, a bullet-shaped member 66 urged by the coil spring 64 is attached to the punching blade 22, or as shown in FIG.
An elastic body 68 of rubber or the like is inserted in the inside. for that reason,
At the moment when the material is punched, the member 66 and the elastic body 68 are pushed into the punching blade 22, and after the material is punched,
The punched chips are pushed out toward the product side, and the punched chips are not accumulated in the punching blade 22.

した。The inventor has installed a bullet-shaped member 66 urged by a coil spring 64 in the conventional punching blade 22, or an elastic body 68 such as rubber in the punching blade 22. In the method of inserting, in consideration of the fact that punching dust adheres to the product or remains between the punching dies, which causes extra processes and defective products, conversely consider taking punching dust into the punching blade. It was However, if the punching waste is simply taken into the punching blade, the punching blade will flatten. Therefore, the present invention has been completed on the idea that the punched chips are discharged from the rear end of the punching blade, and the discharged chips are sucked and discharged by the duct.

When it comes to, the punching waste is compressed and pushed into the punching blade when punching, so when the platen rises after punching, the punched dust that is compressed and accumulated in the punching blade bounces and overflows from the punching blade. There was another problem of getting out.

打抜き屑を分離する余分な工程を必要としない。As described above in detail, the punching device with the punching dust discharging device and the punching method thereof according to the present invention have the blade tip of a cylindrical punching blade projected on the surface and penetrated from the back surface to be fixed to the surface. The bottom of the punching blade fixed to the punching die, which is a stand having a punching die to which an elastic plate is adhered, the punching die being supported from the back and having a punching dust discharge duct inside, with an intake hole at one end and an exhaust hole at the other end. And a punching dust discharging device having a punching dust discharging hole communicating with the punching dust discharging hole.When the material is sandwiched between the punching die and the platen via a pressing plate and compressed, the material is punched together with the pressing plate. The plate punching waste is pushed into the punching blade, but even the punching dust of a thin sheet material that is elastically deformed and compressed during punching does not overflow from the punching blade because it is not pressed by the holding plate. Since the lower end of the blade communicates with the punching dust discharge duct and the punching dust discharge hole, the punching dust falls into the punching dust discharge duct, and the air in the punching dust discharge duct is exhausted from the exhaust hole, so that it is punched out with the air. The waste can be discharged. Therefore, the punching waste and the punched product can be completely separated, and an extra step of separating the punching waste in a later step is not required.
