Large-scale double-curve-surface structure manufacturing multipurpose tooling

Abstract

The invention discloses a large-scale double-curve-surface structure manufacturing multipurpose tooling, which comprises main structure plates, wherein each main structure plate comprises a left side main structure plate, a middle main structure plate and a right side main structure plate in parallel arrangement, the left side main structure plate and the right side main structure plate are respectively welded with the middle main structure plate through a plurality of transverse bars, vertical bars and inclined bars, a bottom plane is processed in the bottom of each main structure plate, the upper end of each main structure plate is in an arc shape, one side is provided with a vertical end plane, the vertical end plane and the bottom plate are mutually vertical, the two sides of the upper end arc-shaped surface of each main structure plate are respectively provided with a semicircular notch, a plurality of weight reducing holes are respectively distributed in each main structure plate, and a middle plane curving line is curved on other outline surfaces of each main structure plate except for the bottom plane. The large-scale double-curve-surface structure manufacturing multipurpose tooling has the advantages that the manufacturing precision of the domestic first large-scale magnetic confinement nuclear fusion vacuum chamber double-curve surface structure can be improved, the cost is reduced, and the workload is reduced.

Description

technical field [0001] The present invention mainly relates to the field of manufacturing nuclear fusion devices, in particular to a multi-purpose tooling for the manufacture of large-scale hyperboloid structures, in particular, in the manufacturing process of the first large-scale hyperboloid structure components of magnetic confinement nuclear fusion vacuum chambers in China. Multi-purpose tooling for pressure forming accuracy measurement, assembly positioning before welding, welding shrinkage and deformation control, heat treatment deformation control, final machining positioning and deformation control. Background technique [0002] Nuclear fusion devices are developing in the direction of large-scale and precision. The hyperboloid structural component of the first large-scale magnetic confinement nuclear fusion vacuum chamber in China has the characteristics of complex structure, high profile requirements, and difficult manufacturing. It is made of multiple pressure-for...

Problems solved by technology

If the control measures are not enough and the profile is out of tolerance, the product may be scrapped

In the manufacture of similar structures in the fields of shipbuilding, aerospace and nuclear industries, the usual practice is to design tooling, fixtures and molds separately in the above-mentioned links, but this will lead to cumulative errors, which is not good for controlling deformation and will increase costs. and workload
