Embodiment Construction

[0036] see Figure 1 to Figure 5 , a method for processing the shape of a composite material forming mold tire 1 thin plate 10 curved surfaces, the main steps are:

[0037] Step 1: Make the basic tire 9

[0038] 1-1 Process all the frame plates 2 and partitions 3 of the composite molding mold tire 1, and produce the overall frame 5 of the mold tire;

[0039] 1-2 Carry out numerical control machining on the upper surface of the overall frame 5, so that the shape of the upper surface of the overall frame 5 is consistent with the shape of the curved surface of the thin plate 10 to be processed;

[0040] 1-3 Equidistant peripheral frame plates 6 are arranged around the overall frame 5, and the upper surface shape of the frame surrounded by the outer frame plates 6 is basically consistent with the upper surface shape of the overall frame 5 of the mold tire 1;

[0041] 1-4 Fill the outer frame plate 6 and the cavity in the overall frame 5 with molding sand 8, and compact it to for...

Abstract

The invention provides a processing method for the sheet curve surface of a composite forming mold. The processing method adapts to manufacturing of various medium-large composite forming molds. The processing method mainly includes the first step of manufacturing of a basic mold, the second step of the first time of forming of the sheet curve surface, and the third step of the second time of forming of the sheet curve surface. By means of the method, refined processing on a curve surface sheet with the thickness being 6 mm or below of the large composite forming mold is achieved by utilizing the methods and principles of thermoplastic forming, hydraulic forming and secondary numerical control processing, and the method has the general applicability to processing and manufacturing of airplane composite forming molds.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing a molded tire made of composite materials, in particular to a method for processing the shape of a thin plate curved surface of a molded tire made of composite materials. Background technique [0002] The molding of the composite material needs to enter the autoclave, and the carbon fiber cloth and the adhesive are cured and formed at about 200 degrees. The thinner the tile steel plate or ordinary steel plate, the better the heat transfer efficiency and speed, and the thicker the support plate, the longer the curing time. [0003] Due to the large size and basically hyperboloid shape of aircraft composite parts, the size of the mold tire is very large and the length even reaches tens of meters. Therefore, the mold tire for composite material molding is generally composed of frame plates, partitions and shape support plates. Due to welding deformation, forming error and numeri...
