Preferably, the side blow hole structure includes side blow fixed part, side blow nitrogen spring, drift fixed plate and drift, the fixed part of side blow is equipped with movable chamber, the slope bottom surface in activity chamber with between the drift fixed plate side blow nitrogen spring, install on the drift fixed plate with side blow edge matched with in the lower profile modeling main part the drift.

Preferably, a contact guide rail matched with the contact slide guide rail is arranged below the side punching fixing main body.

Compared with the prior art, the beneficial effects of the utility model are that:

owing to adopt foretell structural design, the utility model discloses not only intensity is high, the precision is high, is suitable for moreover at progressive die drawing piece fine punching all around and thick hard material blanking.
