Embodiment Construction

[0040] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0041] Such as Figure 1-2 As shown, a thermal diaphragm preforming device for a composite material shell includes a workbench 7, a diaphragm device 12, an insulating door 6, a heating chamber 5, a mold I3, a mold II14, an exhaust system 11 and a control system.

[0042] The workbench 7 is placed on the base, and two identical molds are placed on the workbench 7. The workbench 7 is provided with three stations for feeding, unloading and preforming. The cylinder pushes the workbench 7 along the Move left and right along the longitudinal track, so that the two molds on the workbench 7 are in the "loading + preforming" station or "unloading + preforming" station, that is, two alternate working position states;

[0043] The diaphragm device 12 is installed on the top of the heating chamber 5 and clamps the heat-resista...

Abstract

The invention discloses a composite material box thermal diaphragm pre-forming device and a working method thereof. The device comprises a working table, a diaphragm apparatus, a thermal insulation door, a heating chamber, a mold I, a mold II, an exhaust system and a control system. Compared with traditional thermal diaphragm pre-forming process steps, the working table has the characteristic of double molds and three stations, a preparation link, a machining link and a discharging link are performed at the same time, the whole process steps are optimized, the complexity of the process flow islowered, the pre-forming production efficiency is improved, and the machining period is five minutes per piece. Compared with a mold structure of a traditional thermal diaphragm pre-forming process,a plurality of vacuum pipelines are disposed in the molds, the whole course communicates with a vacuum source, a diaphragm can be completely attached to all R angles, occurrence of failure forms suchas R-angle surface bridging, fiber in-plane buckling and out-of-plane folding is avoided, and the forming quality of the R angles of a box type structure can be improved without change of the processflow.

Description

technical field [0001] The invention belongs to the technical field of composite material preforming, and in particular relates to a thermal diaphragm preforming device for a composite material shell and a working method thereof. Background technique [0002] In the field of equipment manufacturing industry, composite materials have replaced most metal materials with their ultra-high comprehensive characteristics. stacking method. In order to continuously improve the quality of finished products, preforming has become a key link in the entire forming process. Through preforming technology, L-shaped, C-shaped and Ω-shaped composite material preformed products can be obtained; and shells with more complex structures can be prepared. However, it is difficult to realize the preforming technology that can not only guarantee the quality of preforming, but also ensure the production efficiency of body products. [0003] At present, in the preforming process of complex shapes such...
