Abstract
The invention provides a multipoint hot forming device and method for a resin plank. The device comprises a hot-bugling device and a flexible mold device. The hot-bugling device is used for heating and pressurization of the resin plank. The flexible mold device is used for rapid formation of any three-dimensional curved surface resin plank forming mold. By the adoption of the device, organic integration of flexible shape adjustment, controllable temperature adjustment and uniform pressurization is achieved, and fast and flexible formation of the resin plank can be achieved. In addition, the invention provides the multipoint hot forming method for the resin plank. The multipoint hot forming method comprises six steps including shape adjustment through the flexible mold, plank material laying, heating, bulging, pressure maintaining and cooling. The high-quality, efficient and low-cost method is provided for formation of the resin plank through fast shape adjustment through the flexible mold and accurate control over the forming temperature and pressure.
Description
technical field [0001] The invention relates to the field of part processing, in particular to a device and method for multi-point thermoforming of resin plates. Background technique [0002] Resin materials have the characteristics of light weight, high strength, high modulus, fatigue resistance, corrosion resistance, designability, and good manufacturability. It is easy to manufacture large-scale overall structural parts, and has a wide range of applications in aviation, aerospace, automobiles, construction and other fields. . For example, in the field of aviation, resin materials have long been used in aircraft canopies and windshields, and are currently developing fully transparent resin material skinned aircraft; "Province" goal, requiring the mass of the payload to be increased from 40% to 70% of the mass of the aircraft. One of the measures is to use advanced resin-based composite materials instead of metal materials; in the automotive field, many brands of cars in t...
