Abstract

The invention discloses a mould quick replacing system of an FET 1200 type skin stretching former, and relates to the technical field of aircraft skin fabrication. The mould quick replacing system comprises a mould replacing rail device and two movable workbenches; the two movable workbenches are movably arranged on a mould replacing rail; the mould replacing rail device comprises a working area rail device and two preparation area rail devices; the two preparation area rail devices are correspondingly connected with the two ends of the working area rail device; the working area rail device and the movable workbenches are overlooked to be word-king-shaped; and the sizes of word-king-shaped gaps of the working area rail device and the movable workbenches are adaptive. The mould quick replacing system is high in automation degree, moulds are quick and convenient to replace, and the machining accuracy of skin parts is ensured more easily.

Description

technical field [0001] The invention relates to the technical field of aircraft skin manufacturing, in particular to a quick mold replacement system for a FET1200 type skin stretching machine. Background technique [0002] Aircraft skin refers to the three-dimensional component that surrounds the frame structure of the aircraft and is fixed on the frame with adhesives or rivets to form the aerodynamic shape of the aircraft. When making aircraft skins, skin parts are usually made according to the outline of each part of the aircraft frame structure, and then riveted on the aircraft frame to form a complete component. Therefore, the skin parts have complex shapes, many types of products, and small production batches. . [0003] At present, the stretch forming process is usually used to make aircraft skin parts. The FET1200 skin stretch forming machine produced by French ACB company is a kind of equipment used for transverse stretch forming of skin parts. It mainly includes fr...
