Problems solved by technology

[0005] However, it is difficult to realize the densification of large rings with the usual extrusion, forging, rolling and other technologies
On the one hand, it is limited by the tonnage of equipment, such as brake discs for high-speed trains The densification and pressing of aluminum-based composite material rings requires a press with a tonnage of more than 12,000 tons, and there is currently no equipment with this tonnage in China
On the other hand, if extrusion or die forging is used, it is limited by the size and performance of the die, such as for Ring parts, difficult mold preparation

Abstract

A method for compacting the large ring workpiece made up by spray deposition includes such steps as providing a wedge-shaped pressing head having an oblique surface and an oblique smooth transition surface, using an ordinal press to apply a pressure to the large ring workpiece in its mould, gradually pushing the large ring workpiece toward said oblique surface, and pressing whole workpiece. Its apparatus is also disclosed.

Description

Technical field [0001] The present invention relates to a densification processing method, in particular to a method for densification processing of large spray deposition rings. The invention also relates to a device for realizing the densification processing method. Background technique [0002] Aerospace, weapons, high-speed trains and other fields require some large and extra-large lightweight parts, mainly aluminum alloys, magnesium alloys and their composite materials. Such as the front frame of the spacecraft (rings, ), the space station frame ( ), skin (large-area high-performance aluminum alloy or titanium alloy sheet), launch vehicle fuel tank (large plate and frame structure), deep-water torpedo shell ( Reinforced pipes), high-speed train brake discs ( The aluminum-based composite ring). [0003] Among the many metal material preparation technologies, a new type of crucible mobile automatic control spray deposition technology and a series of devices proposed and in...
