Multifunctional extrusion die structure and method

Abstract

The invention discloses a multifunctional extrusion die structure and a method. The multifunctional extrusion die structure and the method solve the problem that volume distribution and interface performance cannot be adjusted and controlled in the prior art, and the structure and the method have the beneficial effect of being capable of flexibly adjusting and controlling material volume distribution, solid-state welding-on conditions, section shapes of extrusion products and other technical parameters and can be used for manufacturing multiple composite rods, plates and hollow profiles. According to the scheme of the multifunctional extrusion die structure and the method, the die structure comprises a porous disc, material containers, extrusion rods, a first die, a second die, a third dieand a die core; holes used for containing the material containers are formed in the porous disc; a cavity is formed in each material container, and the bottom of each cavity is arranged in a hollow manner; the extrusion rods are used for extruding raw materials in the material containers; the first die is arranged below the porous disc; the second die is arranged below the first die in a height adjustable manner, and the first die and the second die are arranged in a hollow manner; the third die is arranged below the second die, and a work band is arranged in the third die; and the die core is arranged at the centers of the three dies and comprises a forming module used for forming a hollow profile.

Description

technical field [0001] The invention relates to a multifunctional extrusion die used for extrusion forming of light alloy profiles, in particular to a multifunctional extrusion die structure and method. Background technique [0002] Composite components learn from each other in terms of performance and can give full play to the advantages of various materials, becoming the focus of modern industry. At present, solid-state welding technologies such as friction stir welding, linear friction welding, diffusion welding, and ultrasonic welding have become the most popular welding technologies for the manufacture of composite materials (such as aluminum-lithium alloys, aluminum alloys, magnesium alloys, copper alloys, etc.) , Hollow member) is an important method. In the process of manufacturing composite components by solid-state welding technology, the mechanical properties of welded joints are often reduced due to the presence of pollutants or oxides on the surfaces to be weld...
