It relates to a pipe forming apparatus, which the pipe is fitted stably clamp, and a plurality of punches installed in a position apart by a predetermined distance from the clamp, which is installed at a position away by conveying part, a distance from the transfer part to which the punch is moved sequentially guide part, fixing part, striking the punch by providing the parts of blow striking the punches by a link provided between the guide portion and the fixing portion forming a pipe at a high speed is fixed at a position apart by a predetermined distance from the guide portion can and, it is possible to blow a large number of punch at a faster rate, can reduce the forming time of the pipe, it is possible to blow link during one round trip of the link driving means reciprocates twice, to strike a punch with a strong impact force and, it is possible to obtain an effect that the pipe forming apparatus can be miniaturized.
