Abstract

The invention provides a method and a device for gluing, pressurizing and curing a fluororubber plate. The method comprises the following steps of: adhering the fluororubber plate (2) on the respective adhering surfaces of a first part and a second part to be adhered by adopting an adhesive; the first pressing plate and the second pressing plate are arranged on the two sides of the fluororubber plate (2) respectively; auxiliary holes are pre-formed in the first pressing plate and the second pressing plate; auxiliary holes are drilled in the fluororubber plate (2), the first part and the second part in a matched mode according to preset auxiliary holes, and a spring clamp (4) is arranged in each pair of auxiliary holes; after the fluororubber plate is pressurized and cured, the spring clip (4) and the pressing plate are taken down; and the auxiliary hole is plugged by adopting an adhesive. By designing and manufacturing a pressing plate consistent with a bonded curved surface in curvature change, after the fluororubber plate is bonded, the pressing plate is fixed on the fluororubber plate, then a fabrication hole is formed, and a spring clip pressurizing and curing mode is adopted through the fabrication hole, so that the technical difficulty of pressurizing and curing in the gluing process of the fluororubber plate on a multi-curved-surface complex part with a cavity structure is solved.

Description

technical field [0001] The invention belongs to the technical field of non-metallic materials, and in particular relates to a method and a device for gluing, pressurizing and curing fluorine rubber plates. Background technique [0002] A product is mainly composed of outer components and middle components. The middle component usually includes multiple composite parts, and multiple composite parts are connected inside the outer component by room temperature curing adhesive, such as figure 1 As shown, the main function is to form a cavity with the outer component for the circulation of gas and liquid. [0003] After the composite parts are bonded, the gap between the parts is bonded with a fluorine rubber plate to prevent airflow from leaking out of the gap. According to the requirements of the fluorine rubber sheet bonding process specification, the fluorine rubber sheet needs to be cured under pressure after bonding. In the bonding process of fluorine rubber sheets, vacu...
