Embodiment Construction

[0032] Such as image 3 , 4 As shown, a forming device for "I"-shaped parts includes a "Ji"-shaped tooling body 8, a positioning block 7, and a non-metallic pressure pad 6. The tooling main body 8 is placed on the bottom layer, and a "C"-shaped structure 2 of the "I"-shaped part is laid on the surface of the tooling main body 8; positioning holes are provided at the corresponding positions of the ears on both sides of the tooling main body 8 and the positioning stopper 7, and the positioning stopper The block 7 is fixed on the ears on both sides of the main body 8 of the tooling, and is used for paving and positioning the upper edge surface 1 and the lower edge surface 5 of the "I"-shaped part; the non-metallic pressure pad 6 is placed on the other "I"-shaped part In the groove of the C”-shaped structure 2, it is used to compress parts and transmit pressure evenly.

[0033] Take the manufacture of "I" shaped long trusses as an example, such as Figure 1-4 As shown, the spec...

Abstract

The invention provides a forming device and a forming method of an I-shaped part. The forming device comprises a tooling main body shaped like the Chinese character ji, a locating stop block and a non-metal pressure pad, wherein the tooling main body is placed at the bottom layer. The forming method comprises the steps of firstly, paving one C-shaped structure part of the I-shaped part on the surface of the tooling main body; then, fixing the locating stop block to two side lugs of the tooling main body for paving and locating the upper and lower edge surfaces of the I-shaped part; and finally, putting the non-metal pressure pad in a groove of another C-shaped structure of the I-shaped part for tightly pressing the part and uniformly transferring pressure. According to the forming device and the forming method, the structure of a tooling is simple, the manufacturing cost of the part is low, the same tooling is utilized in the paving and curing processes, after curing, the demolding is convenient, and the part is not damaged due to demolding.

Description

technical field [0001] The invention relates to the field of composite material manufacturing, in particular to a forming device and method for "I"-shaped parts in aviation vehicles. Background technique [0002] Due to the characteristics of high specific strength and specific modulus, light weight and good corrosion resistance, composite parts have been widely used in aviation, aerospace, shipbuilding, automobile manufacturing and other fields in recent years. [0003] Thanks to its excellent comprehensive mechanical properties, "I"-shaped parts are relatively common structural forms of composite parts in the field of aviation aircraft, including "I"-shaped reinforced wall panels, "I"-shaped long trusses, "I" shaped beams, "I" shaped ribs, "I" shaped ribs, etc. "I"-shaped parts can generally be subdivided into 6 components (such as figure 1 ), including 2 "C" shaped sections, the lower edge face, the upper edge face and 2 R-zone fillers. In the part manufacturing proces...
