In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a deep drawing stamping die, includes mould frame, guide bar, die and terrace die, its characterized in that: the male die and the male die outer cylinder body form an oil cylinder structure, and the male die can be pushed to move up and down along the guide rod through hydraulic pressure; a punch head capable of moving up and down is arranged in the male die.

Preferably, the male die outer cylinder body is welded or fixed with the die frame through a bolt.

Preferably, two pipe threaded holes are formed in the side face of the male die outer cylinder body up and down and respectively include an oil port I and an oil port II, the oil port I is used for feeding oil to push the male die and the punch to move upwards together, and the oil port II is used for feeding oil to push the male die and the punch to move downwards together.

Preferably, the effective length H of the external cylinder body of the male die protrudes below the male die, and the length is greater than the stroke H. Preferably, the bottom of the male die is provided with a threaded hole which can be fixedly connected with the oil cylinder.

Preferably, the lower part of the punch is provided with a threaded hole connected with a connecting block, and the connecting block is connected with the oil cylinder.

Preferably, when the male die is attached to the female die, the oil cylinder works to push the connecting block and the punch to move upwards to stretch the workpiece.

Preferably, the die top have the through-hole, can refuel, and the through-hole top is equipped with the material returned cylinder.

Compared with the prior art, the beneficial effects of the utility model are that: firstly, the drawing and stamping die is provided with an independent power source, and a punch does not need to be additionally arranged; secondly, the structure is simple, and the manufacturing cost is low; thirdly, the speed of the oil cylinder is adjustable, and the oil cylinder is provided with a material returning mechanism and a stretching oil hole, so that deep stretching can be performed.
