The present invention relates to a pipe bidirectional punching press machine and, more particularly, to a pipe bidirectional punching press machine in which regular through-holes can be formed in the pipe or vent holes of various shapes can be formed on one side surface. The present invention includes a mold portion including a first mold portion having a support rod portion protruding at a predetermined length on a lower end outer circumferential surface, having an elastic spring embedded in a central portion, and having a first pin portion for pipe punching at one side end of the elastic spring, a bottom mold portion inserted into and coupled with the support rod portion of the first mold portion, having a guide press portion having a pin hole corresponding to the first pin portion and an insertion groove portion corresponding to the support rod portion of the first mold portion in a central portion, having a supporting elastic member on an upper end outer circumferential surface, and having a second pin portion capable of punching the pipe in the central portion, and a second mold portion having a through-hole between the first mold portion and the bottom mold portion so that the support rod portion of the first mold portion can be inserted therethrough, having a receiving portion on an upper end outer circumferential side surface, and having roller portions in a central portion which are apart from each other and capable of transporting and supporting the pipe, a pin hole corresponding to the second pin portion of the bottom mold portion being formed between the roller portions, a power unit at an upper end of the first mold portion of the mold portion, which is moved upward and downward to transfer a pressing force to the first mold portion of the mold portion, and a base portion connected to and supporting a lower end of the bottom mold portion of the mold portion. |
