Problems solved by technology

[0006] Although this paper discloses that the composite material and the groove of the tiled board are assisted by one-time vacuum forming or step-by-step auxiliary vacuum forming of the tough colloid, but for the composite material embedded board filled in the groove, because the metal frame has a certain large arc, its When the composite material also has a certain large arc with the metal frame (such as the shroud), it cannot use the vacuum-assisted forming process

Embodiment Construction

[0037] The auxiliary device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0038] see figure 1 , figure 2 and image 3 , shown is a metal frame 1 with a dovetail groove connection joint 2, which can be composed of one or more lattices, and the tightness of the welded seams on their end faces (exposed to the outside of the vacuum film coating) must meet the requirements of vacuum degree; metal The surface of the frame 1 should be flat, bright and free of impurities, to ensure that the tightness of the adhesive film 11 and the vacuum film 11 meet the requirements of vacuum degree;

[0039] Figure 4 and Figure 5 Shown is a grid block 3 made of a number of wooden strips 4 at a certain interval, its length and width are slightly smaller than the corresponding metal frame grid, and the thickness size is that after the grid is formed in the grid, the weight of the grid is not enough. ...

Abstract

The invention provides an auxiliary device for vacuum forming based on the connection of composite materials and metal frames, comprising a metal frame with dovetail grooves, the connection surface of the metal frame is provided with longitudinal and transverse concave dovetail grooves, and the dovetail grooves 1. Connected dovetail groove joints; a cavity is formed in the vertical and horizontal metal frame, and a supporting auxiliary device matching the metal frame is arranged in the cavity, and the arc surface of the supporting auxiliary device is adapted to the arc surface of the metal frame. The composite material shell plate and connecting tenon are vacuum formed as a whole, so that the cloth layer glue inside the fiber composite shell plate and connecting tenon is evenly distributed, compact, the proportion of glue content is small, the proportion of reinforcing fiber is large, the strength is high, the connection is reliable, and the fiber is greatly improved. The compression depth and quality of the composite material plate under water are stable, which greatly expands the application range of the combined structure of the fiber composite material shell plate and metal frame.

Description

technical field [0001] The invention relates to a fiber composite material shell plate and its connection with a metal frame, in particular to a composite material shell plate and an auxiliary device for connecting with the metal frame. Background technique [0002] Fiber composite materials have excellent properties such as high strength, light weight, good insulation, corrosion resistance, wave transmission, vibration damping, and easy molding, and are widely used in product shells; metal materials have good strength and stiffness, and can effectively control structural deformation, Generally used in product frame; fiber composite material and metal frame constitute the excellent characteristics of the structure, and its application is more and more extensive. The connection between the fiber composite material shell plate and the metal frame is generally fastened together by metal screws or fiber piles at a certain distance, which is a point connection, and the fiber comp...
