Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-5, the embodiment of the utility model discloses a forging device is hung to casing, including centre form 1 and external mold 2, centre form 1 includes the inner formword and sets up the inner mould chamber 11 in the inner formword, and external mold 2 includes the exterior sheathing and sets up the exterior mould chamber 21 in the exterior sheathing, and when centre form 1 entered into to the interior of exterior mould chamber 21 downwards completely by the opening part in the exterior mould chamber 21 of external mold 2, casing string forging K forges the shaping.

The shape of the inner mould cavity 11 matches the shape of the upper part of the casing hanger forging K. The inner model cavity 11 is provided with a draft angle, the upper part of the casing hanger forging K has a tiny inclination, and the inner model cavity 11 is provided with the draft angle so as to adapt to the casing hanger forging K.

The outer model cavity 21 is of a three-stage hole-shaped structure, the outer model cavity 21 comprises an upper hole cavity 211, a middle hole cavity 212 and a lower hole cavity 213, the diameters of the upper hole cavity 211, the middle hole cavity 212 and the lower hole cavity 213 are sequentially reduced from top to bottom, the shape of the upper hole cavity 211 is matched with the shape of the inner template, the shape of the middle hole cavity 212 is matched with the shape of the middle part of the casing hanger forging, and the shape of the lower hole cavity 213 is matched with the shape.
