SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the utility model is to provide a punching machine reaches the scour protection pressure head dead purpose of card appears.

In order to achieve the purpose, the punching machine comprises a punching head, a fixing seat and a plurality of positioning pins, wherein a cavity is formed in the punching head, a water inlet and a water outlet are formed in the outer surface of the punching head respectively, the water inlet and the water outlet are communicated with the cavity, a plurality of herringbone grooves are formed in the outer surface of the punching head, and the herringbone grooves are arranged on the outer surface of the punching head in an array manner;

the discharge gate has been seted up on the fixing base, the discharge gate with the first mutually supported of punching press, the discharge gate is located the below of punching press head, the bellmouth of downward salient is seted up to the bottom of fixing base, the bellmouth with the discharge gate communicates each other, and is a plurality of the locating pin is all fixed to be set up on the fixing base.

Furthermore, the stamping head is manufactured by adopting a casting process.

Furthermore, the bottom of the stamping head adopts a fillet design.

Further, the number of the positioning pins is three.

Further, a heat insulation layer is coated on the outer surface of the stamping head.

Compared with the prior art, the utility model, its beneficial effect is:

the circulating water system enters from the water inlet and flows out from the water outlet, so that cold water circulation is formed, and circulating cold water is in the stamping cavity, so that the temperature of the stamping head can be effectively and uniformly reduced, and the condition that molten metal is generated in the discharging port of the stamping head is prevented;

even if molten metal is generated, the molten metal can flow into the herringbone groove on the stamping head to prevent the metal from aggregating at the discharge port, and when the molten metal is aggregated into metal particles at the discharge port, the metal particles can be scraped out by the herringbone groove;

the bell mouth is arranged, so that the processed finished product can smoothly flow out of the discharge hole;

to sum up, adopt this kind of punching machine can reach the dead purpose of card appears in the scour protection pressure head.
