Punch, its anterior and described chamber matches, and is used for extruding stock；
Wherein, described die cushion block front end embeds die lower surface, and the edge at die cushion block is provided with blind hole, is provided with horizontal channel at described female bottom, and described horizontal channel is connected with blind hole.
Preferably, also include:
Extruding inner core, it is arranged on the inwall of described chamber, for protecting the inwall of die chamber.
Preferably, also include:
Lead, it is arranged on counterdie, and front end is stretched in guiding column sleeve；
Guiding column sleeve, it is arranged on described die, for coordinating with described lead, it is prevented that produce dislocation between counterdie and die.
Preferably, described die and counterdie are detachably connected by bolt.
Preferably, also include:
