Manufacturing method and product of foamed plate sheet, model aircraft wing

Abstract

The invention discloses a method for manufacturing a foam board sheet. The method comprises the following steps that 1) materials are prepared, and a foam board is divided to be in a preset shape; 2), the sheet is thinned, and the foam board is sliced to be the foam board sheet with the thickness of 0.1mm-1mm through a horizontal cutting machine; 3), the foam board sheet is manufactured into a model aircraft wing. A method for manufacturing the model aircraft wing comprises the following steps of 3.1) printing, 3.2) thermal forming and 3.3) cutting. The model aircraft wing comprises a wing body, the wing body is made of the foam board sheet, and the thickness of the foam board sheet is 0.1mm-1mm. According to the method for manufacturing the foam board sheet, the foam board sheet with the thickness of 0.1mm-1mm can me manufactured, and the performance of resisting bending and being light, elastic and easy to rest is achieved. The method for manufacturing the model aircraft wing is also provided, and the model aircraft wing adopting the foam board sheet is easy to produce in a batched mode. The model aircraft wing is light and thin, and the overall performance of a rubber string power aircraft model is greatly improved.

Description

technical field [0001] The invention relates to the production technology of the foamed plate sheet and the wing of the flying toy, in particular to the production method of the foamed plate sheet, the model aircraft wing and the model aircraft wing. Background technique [0002] Conventionally used foam boards are also commonly known as pearl boards, and most of them are coated on the surface of PS foam boards, which become commonly used KT boards. The foaming ratio of PS material can reach 50 times. At this time, its volume density is about 20kg / m3, and the common thickness is 2mm, 3mm, 5mm. Of course, there are also foam boards made of other polymer materials. However, the current thin foam board with a thickness of 2 mm or less is easy to break during foam molding, the cost of machinery and molds is high, and the product loss rate is high, making it difficult to mass produce. It is even more difficult to make thin foam boards with a thickness of 1mm or less using tradi...

AI Technical Summary

Problems solved by technology

When bending a high-expansion foamed board with a thickness of more than 2mm, the outer layer is broken due to the huge difference in stress between the inner and outer layers, which is easy to damage, and it is difficult to improve the radian shape of the wing.

Moreover, due to its excessive thickness, the air resistance is also relatively large during flight.

[0007] After several months of searching and testing, the inventor found that the above-mentioned problems could not be solved by using existing conventional materials and manufacturing techniques.
