Abstract
The utility model discloses a composite unequal-diameter elliptical punch mold for a boiler and pressure vessel, and aims to solve the problem that a large quantity of limitation and restriction exist in actual seal head production and production requirements cannot be met more due to the fact that besides rotary extrusion forming, a present frequently-used elliptical seal head of the boiler and pressure vessel is commonly obtained through compression forming by an integral elliptical punch mold or an elliptical punch mold composited by a spherical seal head with an equal diameter and an insert. The composite unequal-diameter elliptical punch mold consists of an integral spherical punch mold (1) and an unequal-diameter elliptical insert mold (2), wherein a spherical surface is formed at one end of the integral spherical punch mold; a concave surface matched with the spherical surface is formed at one end of the unequal-diameter elliptical insert mold; an elliptical convex surface is formed at the other end of the unequal-diameter elliptical insert mold; and the integral spherical punch mold and the unequal-diameter elliptical insert mold are connected. The composite unequal-diameter elliptical punch mold is used for mold compression.
