DETAILED DESCRIPTION

[0017] The special-shaped cabin forming process provided by the present application will be explained and described in detail below in conjunction with the accompanying drawings of the specification.

[0018] At present, composite cabins are usually processed and formed by a vacuum negative pressure adsorption integrated forming process, but in special-shaped cabins, there are more cabin plate shapes and quantities involved. The vacuum negative pressure adsorption integrated forming process needs to use too much adhesive in the forming process, especially the adhesive is poured between the two adjacent parts, which will cause the final formed cabin to exceed the weight standard, and integrated forming is not conducive to precise control of local angles, sizes, etc.

[0019] Based on this, the present application provides a special-shaped cabin forming process, which uses a split forming process to form each part of the cabin, and then assembles on an assembly tool, so that glueing and bonding can only be performed at the connection between each part, and the use of adhesive can be reduced. During assembly, the angles, gaps, etc. of each part can be adjusted on the assembly tool, and the parts are connected after the parameters meet the standard. The weight of the cabin formed by the present application can be controlled, the shape size, especially the angle of the key parts, can be guaranteed, and the quality of the cabin can be improved. The present application will be described in detail below in conjunction with specific embodiments: In some embodiments, the present application provides a special-shaped cabin forming process, which is composed of a composite material, and includes cabin plates and special-shaped segments.

Optionally, during the forming process of each part of the cabin, according to the structure form, appearance after forming, and weight requirements of each part, each part is formed by a split forming mold. Among them, the special-shaped segment needs to be smooth on the inside and outside, and the single-sided mold is optimized to a mold pair, i.e. a male and female mold, to improve the smoothness of the inside and outside of the formed product.
