Semi-solid molding equipment and process for non-ferrous metal particles

Abstract

The invention discloses a non-ferrous metal granule semi-solid forming equipment, comprising: a section horizontal feeding mechanism, the said one section horizontal feeding mechanism is used to realize metal particle transportation, melting, mixing, storage, into the molding cavity; the one-section horizontal feeding mechanism is equipped with: a barrel device arranged horizontally, a segmental gradient heating system set outside the barrel device, and a shear opening structure with the barrel device The docked material storage device and the drying system arranged outside the material storage device; the two-section vertical forming mechanism, the two-section vertical forming mechanism is used to realize die forging and die-casting; the one-section horizontal feeding mechanism The working direction of the two-section vertical forming mechanism is perpendicular to that of the two-section vertical forming mechanism, and the first-section horizontal feeding mechanism is internally connected with the second-section vertical forming mechanism, and the horizontal feeding is realized through a smooth-type discharge port. , vertically shaped. Also disclosed is a non-ferrous metal particle semi-solid molding process.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal particles semi-solid forming process and equipment, in particular to a non-ferrous metal particle semi-solid forming process and equipment. Background technique [0002] The existing aluminum-magnesium-zinc non-ferrous metal particle semi-solid die-casting molding equipment is the most novel and cutting-edge metal material molding process equipment after the liquid metal die-casting molding process equipment. The semi-solid forming process equipment die-casts various thin-walled parts with excellent quality In liquid die-casting, good compactness. All aspects of mechanical properties are better than liquid metal die-casting parts. For example, the tensile strength of the aluminum-magnesium-zinc alloy is significantly increased by more than 20-25% after semi-solid forming. But at present domestic and foreign vertical or bedroom semi-solid die-casting molding equipment all adopt axial mo...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a semi-solid forming equipment for non-ferrous metal particles such as aluminum, magnesium and zinc, which breaks through the bottleneck of the existing metal semi-solid forming equipment, that is, solves the problem that the existing forming equipment can only form small specifications, light weight, and thick walls. Parts products with less drop, it is difficult to form super large, super thick and heavy large parts and prefabricate various large blanks, and solve the existing horizontal and vertical semi-solid forming equipment for aluminum, magnesium and zinc metals, using axial feeding , molten material, high-pressure and high-speed unidirectional injection molding process, which greatly restricts the application scope of existing aluminum, magnesium, and zinc metal semi-solid equipment.
