Preferably, the die is the back taper sleeve structure of back taper for the periphery, the inner circle of back taper sleeve structure is the die cavity of the microcephaly of shaping gate valve lid forging, the diameter of the inner circle of back taper sleeve structure and the diameter phase-match of the microcephaly of gate valve lid forging.
Further preferably, the upsetting die comprises a stepped hole-shaped cavity matched with the shape of the gate valve cover forging.
Further preferably, the forging device of the gate valve cover forging piece uses a hammer head to hammer the die to press one end of the blank.
Further preferably, the forging device of the gate valve cover forging piece adopts a hammer head to hammer the other end of the blank so that the blank is fully upset in the stepped hole-shaped cavity.
Preferably, the upper end of the upper hole of the stepped hole-shaped cavity is provided with a fillet, and the upper end of the lower hole of the stepped hole-shaped cavity is provided with a fillet.
Preferably, the die is clamped by a clamp to the bottom end of the blank during swaging of the small end of the gate cover forging.
Compared with the prior art, the invention has the advantages that:
1) the utility model provides a forging device of gate valve lid forging can directly forge gate valve lid forging shape out through the die with the full mould of upsetting for the fibre direction of forging distributes along with the shape, and product quality is reliable and stable, has anti high pressure and anticorrosive characteristic.
2) The utility model provides a forging device of gate valve lid forging can once only forge the shaping product, has saved the turning step among the prior art, has reduced the machining step, has reduced the blank dead weight, has shortened processing cycle for the comprehensive mechanical properties and the life of gate valve lid are improved.
3) Meanwhile, because the machining steps are reduced, the excess materials generated by machining are also reduced, and the manufacturing cost is reduced.
