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[0061] After the high-temperature parts are withdrawn, the upper and lower folding mechanisms operate at the same time, and the upper and lower skins are b...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[0065] After the high-temperature parts are withdrawn, the upper and lower folding mechanisms operate simultaneously, and the upper and lower skins are bo...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...
