FIELD: technological processes.
SUBSTANCE: invention relates to hot-forming tooling. Puncheon is composed of a body, a front working part in the form of a fungus with a conical hollow stem having an internal thread, and a bolt. Fungus foot is arranged in conical cavity formed from front end face of housing, and is open to through cavity of smaller diameter. Bolt is installed in the through cavity of the body, and its head is made with a front conical end face and is placed in the cavity of a larger diameter with a conical bottom formed from the back end of the body. Front conical end of bolt head is thrust against conical bottom, and rear end is recessed relative to rear end of housing. Bolt is threaded on its front part is connected with internal thread of hollow stem of fungus, spaced by rear end from front end of housing.
EFFECT: result is reduced consumption of high-quality tool steel for production of puncheon, possibility of its repair.
