A bend pipe forging die with spring material device

Abstract

A bend pipe forging die with a springing device comprises a fixed die body and a movable die body, wherein the movable die body is arranged below the fixed die body; a convex die body is arranged on a forging surface of the fixed die body; a concave die body which is matched with the convex die body is arranged on a forging surface of the movable die body; the convex die body is matched with the concave die body to form a forging cavity of which the shape is matched with that of a bend pipe; the springing device is arranged in the movable die body; a downward blind hole is formed in the forging surface of the movable die body; the springing device comprises a first spring arranged at the bottom of the blind hole and a pressure lever arranged on the first spring; the upper end of the pressure lever extends out of the blind hole; the upper part of the pressure lever is a wedge-shaped surface; a through hole is formed in a position, which corresponds to the forging cavity, of the wedge-shaped surface; a push rod which is matched with the wedge-shaped surface of the pressure lever is arranged in the through hole; and a resetting spring is arranged on the push rod. The springing device is arranged in the movable die body, so that a finished bend pipe can be unloaded from the die when stripped from the die; the labor intensity of workers is reduced; and the forging efficiency of the bend pipe is improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of forging dies, and in particular relates to an elbow forging die with an elastic material device. Background technique [0002] The forging mold refers to heating the metal first to become a liquid or softened state, then putting it into the mold, and forming it at one time by closing the upper and lower molds of the mold. The advantage of forging and casting is that casting is to pour heated molten metal directly into the mold, while die forging also needs to be closed by the upper and lower molds. The closing of the upper and lower molds makes the product subject to extrusion force during the molding process, and its structure and mechanical properties have been enhanced. [0003] The die used for forging the bent pipe has a cavity designed in the shape of the bent pipe. The existing forging die for the bent pipe usually has a slow demoulding speed and low work efficiency. The utility model patent with...
