Problems solved by technology

For the S-shaped profile with a large height (greater than 140mm), it cannot be rolled and formed as a whole. At the same time, due to the small thickness of the part material, it cannot be formed with ordinary stretch bending equipment. Therefore, the part must be divided into the above parts during part production. The edge strip and the lower edge strip are formed separately, and finally riveted with the connecting plate as a whole ( figure 1 )
The manufacturing process of this kind of parts is cumbersome, the number of tooling required is large, the manufacturing cycle is long, and the weight of the parts is increased

Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings.

[0015] The forming process equipment includes two parts: a bending die and a bending chuck:

[0016] 1. The bending die consists of an upper die 1, a backing plate 2, a lower die 3, and a serpentine block assembly 4. The upper die 1 and the backing plate 2 are arc-shaped parts, and the lower die 3 is a cuboid. The length of the lower die 3 is the same as that of the upper die. 1. The chord length of the backing plate 2 is the same, and the upper die 1, the backing plate 2 and the lower die 3 are connected as a whole with screws 5 around, and fixed with pins 6 evenly along the arc length of the upper die 1. The profile 14 has the same cross-sectional dimensions, and the radian along the length direction is consistent with the radian of the S-shaped profile 14 .

[0017] 2. The serpentine block assembly 4 is composed of a plurality of core blocks. Each core block 7 is c...

Abstract

The invention belongs to a sheet metal part molding art and relates to S-shaped section molding process equipment. The molding process equipment comprises a bending mold and a bending clamp, wherein the bending mold comprises an upper mold, a base plate, a lower mold and an S-shaped block assembly; and the bending clamp comprises a left clamp and a right clamp. In the invention, the bending mold is adopted and is matched with the bending clamp to implement an S-shaped section integral bending and molding art, thereby providing a solution for optimizing the structure of a product, lightening the weight of the product, enhancing the manufacturability of the product, reducing the number of the process equipment in the production engineering of the product, shortening the manufacturing period of the product, simplifying the assembling flow of the product, enhancing the production efficiency of the product and lowering the production cost of the product.

Description

technical field [0001] The invention belongs to sheet metal parts forming technology, and relates to an S-shaped profile forming process equipment. technical background [0002] The S-profile is a profile part that connects the skin and the long stringer on the aircraft. The common cross-sectional shape of the part is ( figure 2 ), for the forming of S-shaped profile parts with small height and size, the process method of roll bending is generally used at present. For S-shaped profiles with large height dimensions (greater than 140mm), they cannot be rolled as a whole. At the same time, due to the small thickness of the part material, the parts cannot be formed by ordinary stretch-bending process equipment. Therefore, the parts must be divided into upper parts during production. The two parts of the edge strip and the lower edge strip are formed separately, and finally riveted with the connecting plate as a whole ( figure 1 ). This kind of part manufacturing process is c...
