Embodiment Construction

[0036] The flexible mold for profile stretch bending according to the present invention will be further described in detail below in conjunction with the accompanying drawings. A flexible mold for profile stretch bending, such as figure 1 and figure 2 As shown, it includes an X-direction positioning assembly 1, a Z-direction adjustment assembly 2 and a punch assembly 3. The X-direction positioning assembly 1 can adjust the position of the Z-direction adjustment assembly 2 in the X direction, that is, adjust the Z-direction adjustment assembly 2 in the X direction. figure 2 The position in the horizontal direction, the punch assembly 3 contains a plurality of height-adjustable punches 33, and the Z-direction adjustment assembly 2 can adjust the position of each punch 33 in the punch assembly 3 in the Z direction, that is, adjust the punch assembly 3 in each punch 33 in figure 2 position in the vertical direction.

[0037] The X-direction positioning assembly 1 includes a ...

Abstract

The invention provides a flexible mold used for profile stretch bending. The flexible mold comprises an X-direction positioning assembly (1), a Z-direction adjustment assembly (2) and a punch assembly (3), the X-direction positioning assembly (1) can adjust the position of the Z-direction adjustment assembly (2) in the X direction, the punch assembly (3) comprises a plurality of punches (33), and the Z-direction adjustment assembly (2) can adjust the position of each punch (33) in the punch assembly (3) in the Z direction. The flexible mold can meet production requirements of small-batch stretch bending of airplane profiles with a plurality of types, the mold design and manufacturing cycle is shortened, the number of molds is reduced, and the airplane development speed is increased. The flexible mold used for profile stretch bending can also be used for stretch bending production work of airplane profiles differing in specification and curvature.

Description

technical field [0001] The invention relates to the technical field of skin stretching, in particular to a flexible mold for profile stretching and bending. Background technique [0002] Aircraft skin parts are important covering parts of aircraft, and are widely used in the wings and fuselage of aircraft. They have complex and diverse shapes, large structural sizes, and various types. The number of single machine parts accounts for about 30% of the entire sheet metal parts. Skin drawing is the main forming method of aircraft skin parts, and its advanced degree is an important symbol to measure a country's aircraft manufacturing capability and level. [0003] Aircraft profile parts are the key components of the aircraft, and are important components of beams and ribs. They are widely used in the wings and fuselages of aircraft. High precision is required, and it is mostly manufactured by stretch forming (abbreviated as stretch) method, which is the main process of aircraft ...
