Problems solved by technology

However, since the material is still hot when the mold is opened, the upper and lower skins tend to open up again, causing the edge closure to fail
[0008] In short, the edge closure of plastic honeycomb sandwich panels is still a technical problem in the industry

Embodiment 1

[0059] First prepare the plastic honeycomb sandwich panel with glass fiber reinforced PP on the upper and lower skins and PP honeycomb in the middle, and cut to Figure 4 The range shown by the solid line. The dotted line is the outline of the product, the solid line is the outline of the plate, and the area between the solid line and the dotted line is the edge banding area of ​​the product. The width of the edge banding area is set to 7mm.

[0060] After the plate is positioned and fixed on the tooling, a high-temperature component with a thickness of 13mm and a temperature of 220°C is inserted on the side of the plate. After the high-temperature component is inserted in place, if Figure 5 As shown, the honeycomb outside the outline of the product is completely melted, and the upper and lower skins are also softened.

[0061] After the high-temperature parts are withdrawn, the upper and lower folding mechanisms operate at the same time, and the upper and lower skins are b...

Embodiment 2

[0063] First prepare the plastic honeycomb sandwich panel with glass fiber reinforced PP on the upper and lower skins and PP honeycomb in the middle, and cut to Figure 4 The range shown by the solid line. The dotted line is the outline of the product, the solid line is the outline of the plate, and the area between the solid line and the dotted line is the edge banding area of ​​the product. The width of the edge banding area is set to 20mm.

[0064] After the plate is positioned and fixed on the tooling, a high-temperature component with a thickness of 13mm and a temperature of 300°C is inserted on the side of the plate. After the high-temperature component is inserted in place, if Figure 7 As shown, the honeycomb outside the outline of the product is completely melted, and the upper and lower skins are also softened.

[0065] After the high-temperature parts are withdrawn, the upper and lower folding mechanisms operate simultaneously, and the upper and lower skins are bo...

Embodiment 3

[0067] First prepare the plastic honeycomb sandwich panel with glass fiber reinforced PP on the upper and lower skins and PP honeycomb in the middle, and cut to Figure 4 The range shown by the solid line. The dotted line is the outline of the product, the solid line is the outline of the plate, and the area between the solid line and the dotted line is the edge banding area of ​​the product. The width of the edge banding area is 14mm.

[0068] After the plate is positioned and fixed on the tooling, a high-temperature component with a thickness of 13mm and a temperature of 300°C is inserted on the side of the plate. After the high-temperature component is inserted in place, if Figure 7 As shown, the honeycomb outside the outline of the product is completely melted, and the upper and lower skins are also softened.

[0069] After the high-temperature parts are withdrawn, the lower skin turning mechanism acts to stick the lower skin to the side wall of the plastic honeycomb; t...

Abstract

The invention relates to a method for sealing an edge of a plastic cellular sandwich board and an apparatus thereof. According to the invention, an edge sealing zone is arranged outside the contour of a product, in the edge sealing zone, a high-temperature part is inserted between an upper skin and a lower skin of the edge, honeycomb is removed through fusing, the upper skin and the lower skin are softened, and then the upper skin and the lower skin are turned to a center, so that edge sealing of the product is realized. According to the edge sealing method, the product edge is full and firm, the product edge intensity is enhanced, the problem of edge enclosing of a PPHC material is solved, and an application of the PPHC material on a spare wheel cover plate is promoted.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an edge sealing method for a plastic honeycomb sandwich panel. Background technique [0002] The honeycomb sandwich structure has the characteristics of light weight and high strength due to its hollow structure, and is widely used in automobile spare tire covers. [0003] The common honeycomb sandwich spare tire cover has two materials, one is PHC board (abbreviation of Paper HoneyComb, polyurethane spraying process), the core material is honeycomb paper, the skin is glass fiber reinforced polyurethane foam, and the other is plastic honeycomb Sandwich panel, the skin is glass fiber reinforced plastic, and the core material is plastic honeycomb. Among the plastic honeycomb sandwich panels, the typical one is PP honeycomb sandwich panel, referred to as PPHC board (abbreviation of PolyPropylene HoneyComb, dry process), the core material is PP honeycomb, and the skin is...
