Vacuum forming machine applied to airplane panel

Abstract

The invention discloses a vacuum forming machine applied to an airplane panel. The vacuum forming machine comprises a heating system, a vacuum compression system and a control system; the heating system can provide proper temperature for the vacuum film pressing process, the vacuum compression system can provide a proper vacuum degree for the vacuum forming film pressing process, vacuum film pressing is conducted on the airplane panel by means of a high temperature environment provided by the heating system, the control system comprises a PLC and an electric control cabinet, a power supply system, a temperature control system, a time control system and a vacuum degree control system are connected to the PLC respectively, program control is conducted on regulating operation of the heating system and the vacuum compression system, and the electric control cabinet is an installation carrier of the PLC, the power supply system, the temperature control system, the time control system and the vacuum degree control system. The vacuum forming machine is convenient to operate, safe and durable, control over conditions of the temperature, vacuum degree, time and the like in the film pressing process is easy and rapid, and manual control and automatic control can be switched conveniently according to needs.

Description

technical field [0001] The invention belongs to the field of aircraft manufacturing, and relates to a film coating device for aircraft panels, in particular to a vacuum forming machine applied to aircraft panels. Background technique [0002] There are a large number of panels in the aircraft cabin, including flat panels and three-dimensional curved panels, such as side wall panels, emergency window panels, ceilings, etc. The outer surfaces of these panels are covered with aircraft wallpaper. The molding of aircraft wallpaper includes manual molding and thermal vacuum molding. During the pasting and molding process of aircraft panel wallpaper, both the panel and the inner surface of the wallpaper are sprayed with glue, the wallpaper is covered on the panel, the wallpaper is evenly heated, and then pressure is applied above the wallpaper to soften and deform the wallpaper, and the wallpaper and side walls The glue between the boards relies on intermolecular force, mechanical ...

AI Technical Summary

Problems solved by technology

[0004] For the coating device of the aircraft panel, the heating device of the vacuum forming machine currently used mostly adopts imported 110V infrared lamps, which are not produced in China and are difficult to replace after damage, and are highly dependent on foreign supply; for the control system, its control Most of the methods use Continental instruments, which are not intuitive enough, complicated to operate, and difficult for beginners to master, which affects the molding efficiency of aircraft cabin panel wallpaper. During the process of laminating temperature, pressure and other data records, old paper tape printers are often used, and the operation is cumbersome. The change process of conditions such as temperature and pressure is not intuitive, and the heating time of the heating system from one temperature to another temperature cannot be controlled artificially, which will affect the quality and yield of the aircraft cabin panel wallpaper molding, and reduce the film covering efficiency; for the current For the vacuum forming machine used to process aircraft panels, the vacuum degree of the vacuum obtaining device drops slowly, and the vacuum level can only be adjusted manually, which is inefficient and difficult to operate; due to the lack of leakage protection function, the equipment damage rate is high and even causes Safety accidents, once damaged, affect the processing process and high repair costs
