Description

Background

The quenching deformation control of the sheet metal part is a problem which is generally accepted and difficult to solve in the industry, and the quenching deformation control problem of the clamping area of the large-size sheet metal part is always an important problem which hinders the improvement of the production efficiency and the processing precision of parts.

The project takes a 5-meter melon petal of a carrier rocket as a research object. The melon lamella of 5 meters is the important sheet metal component of carrier rocket. The product profile structure is complicated, the product quality requirement is high, the product raw material plate width is 4000 x 2100mm, the material specification is mostly concentrated in 6 to 7mm, and the product belongs to a typical large-size sheet metal part.

Solution treatment (commonly referred to as quenching treatment) includes two processes of solution strengthening (high temperature phase) and rapid cooling (quenching). Solution treatment, commonly referred to as quenching, is an essential process to obtain a supersaturated solid solution, whereas supersaturated solid solution desolventization is the basis for heat treatment of a heat-treatable aluminum alloy for strengthening heat treatment (quenching and aging). The heat treatment method in which the quenched aluminum alloy part is kept warm at room temperature (natural aging) or at a higher temperature (artificial aging) and then air-cooled is called aging treatment, and the object is to precipitate a strengthening phase from a supersaturated solid solution.

The 5-meter scale melon petals are subjected to single-furnace single-piece inclined quenching treatment. When quenching treatment is carried out, in order to ensure that the jaw part of the product has small deformation, a bow-shaped clamp is adopted for clamping.

The melon lamella of 5 meters level is because melon lamella slope quenching in the quenching process, receives heating deformation and the dual influence of income water impact deformation, and the quenching deformation is great, and maximum deflection is about 350mm, can't satisfy in the follow-up clamping requirement 50 mm.

The quenching of the 5-meter-level melon petals adopts single-furnace single-piece quenching, and the time of the quenching procedure is about 3h per piece (including charging and discharging). Because the heat treatment deformation is large and the final drawing clamping requirement cannot be met, the subsequent final drawing process can be carried out only after the shape correction is needed, and the time for correcting single pieces is about 0.5 h/piece. Seriously affecting the whole production efficiency of the melon petals.
