摘要
The present invention discloses a forward and backward extrusion composite forming method using a mould having an open inner cavity, including the following steps: (1) the structural design and assembly of the forward and backward extrusion composite mould having the open inner cavity; (2) the preparation of the initial billet; and (3) forward and backward extrusion composite forming. The present invention can greatly improve the length-diameter ratio of the blind hole and is widely used in alloy steel, aluminum alloy, magnesium alloy, copper alloy and other components.
