Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation materials, in particular to a composite device with uniform force. Background Art

[0002] Thermal insulation materials are divided into three categories: porous materials, heat-reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of air or inert gas in the pores is very low, such as foam materials, fiber materials, etc.; heat-reflective materials have a high reflectivity and can reflect heat, such as gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials use the internal vacuum of the material to block convection to insulate heat. The aerospace industry has strict requirements on the weight and volume of the thermal insulation materials used, and often requires it to have sound insulation, vibration reduction, corrosion resistance and other properties. The needs of various aircraft for thermal insulation materials are different. Foam plastics, ultra-fine glass wool, high silica wool, and vacuum insulation panels are often used for insulation in aircraft cabins and cockpits. For example, composite insulation floors need to be pressed and shaped during the production process.

[0003] Prior art publication number: CN210705229U, provides a technical solution: a pressing device for producing composite heat-insulating floor, including a base, the top of which is fixedly connected to a pressing table. The pressing device for producing composite heat-insulating floor, through the use of a slide rail, has a slide groove inside the slide rail, and the slide groove matches the slide rod inside the movable frame, so that the movable frame can slide inside the slide rail, and through the use of a motor, the motor can drive the cleaning device to rotate quickly inside the movable frame, when it is necessary to clean the inside of the pressing table, the push rod is pushed by hand to make the movable frame flip 180 degrees inside the slide rail, and the movable frame can enter the inside of the pressing table under the action of its own gravity, and then the motor is turned on to make the sanding block on the cleaning device rotate quickly, and the residue inside the pressing table that is difficult to clean is quickly cleaned, thereby achieving the purpose of automatic cleaning, improving work efficiency, and facilitating use.

[0004] but:

[0005] When this solution is used, the first shock-absorbing plate, the shock-absorbing block and the second shock-absorbing plate are used in conjunction with each other. The hydraulic cylinder drives the pressing block to move downward for pressing. The pressing block is prone to deviation during the pressing process due to the lack of limit on the material at the bottom, resulting in uneven force during pressing and quality defects.
