Embodiment Construction

[0012] The parts of the work of the present invention are composed of a vacuum box, a rubber sealing ring and a model plate engraved with a pattern shape that needs to be cut, and need to be used in conjunction with a vacuum pump. The vacuum box is made of 8mm acrylic board, which is a sealed container without a cover, such as figure 1 Shown, have the hole that is used for pumping on the case wall of vacuum box 2, install the suction pipe connector on the hole, use leather tube to be connected with the vacuum pump on the suction pipe connector on the vacuum box. The model plate is also made of 8mm acrylic plate, and the surface of the model plate is engraved with a 1mm deep and 0.2mm wide tool groove along the pattern outline with a two-dimensional engraving machine. Excess air from the acrylic model plate. The gap between the model plate and the vacuum box is sealed tightly with a sealing ring. The sealing ring is sprinkled with water to improve the sealing effect. A closed...

Abstract

The invention provides a high-accuracy flexible thin film shape preservation cutting device which mainly solves the problems that a thin film is easily wrinkled and deformed due to stretches in the machining process. According to the technical scheme, the high-accuracy flexible thin film shape preservation cutting device is characterized in that low pressure is generated through a vacuum pump, so that a thin film is attached to a flat model board and is then cut. Thus, the thin film can be tightly attached to the flat board, it is guaranteed that the thin film is not moved and is flat all the time in the thin film cutting process, the tension degrees of all positions of the whole thin film are uniform and identical, and the thin film is prevented from being irrecoverably deformed by stretches. The cutting device is simple in shape and convenient to machine and a finished device product is already completed in a laboratory. In addition, the cutting device is high in flexibility and capable of being used for manual cutting operation and used in cooperation with a numerical control machine tool, the shape accuracy of the thin film can be effectively guaranteed, a small number of complex shapes can be machined, the advantages of the device are more remarkable when the device is used for batch production, and production efficiency can be effectively improved while cutting accuracy is guaranteed.

Description

Technical field: [0001] The invention relates to a high-precision cutting device, which is used for cutting complex shapes of flexible film materials. It belongs to the field of film material cutting. It can complete the cutting of complex shapes with high precision, and can effectively avoid wrinkles and bubbles in the film. During mass production, it can ensure that the tension of each finished film is consistent. Background technique: [0002] In the research and production process of orthopter and fixed-wing aircraft models, it is inevitable to need a large number of cutting film products for the flapping wings of orthopters and the skin of fixed-wing aircraft models. Especially for the orthopter, which is a small, light, maneuverable micro-aircraft, the precision, tension, and wrinkles of the film flapping wing will not only affect its appearance, but also have a fatal impact on the aerodynamic performance of the orthopter. Impact. The loss of long-term flapping win...
