Multidirectional die-forging forming die and forming method of valve forge part with main flange

Abstract

The invention relates to a multidirectional die-forging forming die and forming method of a valve forge part with a main flange. The die comprises a lower die body; a left die body and a right die body are arranged on the upper portion of the lower die body; the left die body is connected with a left horizontal cylinder through a left horizontal connection rod; the right die body is connected with a right horizontal cylinder through a right horizontal connection rod; an upper die body is arranged above the left die body and the right die body and connected with an upper die upper cushion plate; the upper die upper cushion plate is connected with a moving beam; a through hole is formed in the middle of the upper die body; a center hole is formed in the middle of the upper die upper cushion plate; a vertical cylinder is arranged above the upper die upper cushion plate; the lower portion of the vertical cylinder is connected with an upper punch; the upper die body, the lower die body, the left die body, the right die body and the upper punch form a closed cavity. The multidirectional die-forging forming method of the valve forge part with the main flange can forge the main flange and a vertical hole at a time, reduce the weight of the forge part, improve the forging efficiency, improve the precision of the forge part, and reduce the production cost.

Description

technical field [0001] The invention relates to a forging method, in particular to a multidirectional die forging forming method of a valve body forging with a main flange. Background technique [0002] At present, two forming methods are used for valve body forgings, namely ordinary die forging and multi-directional die forging with horizontal split die. During ordinary die forging, there are flashes on the parting surface, and horizontal holes and vertical holes cannot be forged at the same time. The weight of the forging is large and there is a lot of material waste. Although the multi-directional die forging of the horizontal die forging method can forge horizontal holes and vertical holes, it cannot forge the main flange, resulting in heavy weight of the forged parts after machining and difficult installation. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a multi-directional die forging ...
