Abstract

The invention discloses an aluminum pipe extrusion die with rotary shearing force. The die comprises an upper die body. A die core is arranged in the center of the lower end face of the upper die body; a double-cone body is arranged in the middle of the die core; the double-cone body is divided into an upper cone body and a lower cone body; the upper cone body and the lower cone body are containedin a welding chamber; the lower die body is arranged right under the upper die body; and a cylindrical straight gear is arranged on the outer side of the lower die body. The die is simple in structure; die repairing and die changing are convenient; the gear of the lower die is engaged by an external gear and is driven to rotate; the surface of the upper cone body in the middle of the upper die core can achieve a flow guide effect, so that the aluminum material can rotate more sufficiently in the welding chamber formed by the lower die and the upper die; the aluminum material is sheared and deformed in the rotating process, so that grains of the aluminum material are further refined; and the aluminum material is welded after rotating, and the mechanical property of an extruded aluminum pipe is improved, so that the quality of the aluminum pipe is improved.

Description

technical field [0001] The invention relates to the technical field of alloy pipe manufacture, in particular to an aluminum pipe extrusion die with rotating shear force. Background technique [0002] The hot extrusion of aluminum pipe is based on the good plasticity of the material at the hot forging temperature, and it is extruded; different molds and different die cores will also change the mechanical properties and quality of the extruded pipe. [0003] Chinese patent 201820391033.7 discloses an aluminum pipe extrusion die. When the pipe extrusion die is extruding, the aluminum rod enters the shunt channel under the action of the press to balance the force in the middle of the metal, so that the abrasive The metal flow in the pipe is reasonably distributed to avoid the occurrence of extrusion dead ends, and finally the aluminum pipe is obtained after flowing out from the ring-shaped forming hole. This patent can distribute the metal evenly and bear the force in a balance...
