Description

A kind of timeliness tooling

Technical field

The utility model relates to mechanical technology equipment technology fields, more specifically to a kind of timeliness tooling.

Background technique

It is generally known that heat treatment can reinforced aluminium alloy material is obtained by solution hardening and timeliness needed for tissue and property Can, articles made of aluminium alloy needs Putting into water rapidly to quench after high temperature solid solution, will lead to product because product inhomogeneous cooling is even in quenching and produces Raw quenching distortion.

For super-huge aluminum alloy ring forging needed for heavy launcher, material is that 2219 heat treatments can reinforced aluminum conjunction Gold, ring outer diameter 9500mm~φ 9620mm, about 10m.It is deformed after 10m aluminium alloy rings solution hardening very greatly, therefore, 10m aluminium There are biggish deviation from circular froms, such as the maximum out-of-roundness that can reach 50mm after alloy rings quenching, before timeliness.

How the deformation of ring is reduced, and there is no preferable modes in the prior art.After usual workpiece quenching, directly carry out Aging sequence carries out aging strengthening model that is, directly aluminium alloy rings are placed in material frame or material frame, and ring does not need additional appoint What tooling, ring in ag(e)ing process in no restrained condition, the geomery of ring before timeliness, it is almost the same after timeliness, Therefore, the deviation from circular from of ring is still larger after timeliness.

In order to realize the accurate control shape in ag(e)ing process, creep age forming is gradually developed.Its cardinal principle is benefit Slow deformation is synchronized by creep rig in ag(e)ing process with material, after completion of prescription, product also completes final forming. However, country's creep age forming technology is proved still in development phase, the design of the aluminium alloy large-sized creep ageing furnace of 10m at present Work is also not yet carried out, moreover, carrying out large-scale creep ageing furnace design, manufacture research, research and development and manufacturing expense are very high, cost Greatly.

It is current art technology in conclusion how to provide a kind of timeliness tooling that can have both school circle shaping feature Personnel's urgent problem to be solved.
