Problems solved by technology

[0005] However, the disadvantages of the above design method are: (1) The processing method of the mold has not changed, and it is still obtained by mechanical processing, so it is difficult to ensure and improve the accuracy of the mold surface
(2) The mold surface compensation method is the mold surface compensation amount and compensation equation calculated under the assumption of a uniform temperature field, which is somewhat different from the actual temperature field of the mold, and it is difficult to directly apply it to engineering

Abstract

The invention discloses a design device and a design method of an adjustable composite-material mold. The device mainly comprises a mold profile, an adjusting device, an adjusting tool, a mold supporting back frame and an angle sheet, wherein the adjusting device is arranged on one side of the mold profile and equipped with a linear displacement feeding function; and the mold profile is connected to the adjusting tool by the adjusting device, a datum point on the adjusting tool is used to measure accuracy of the mold profile in order to obtain a normal displacement deviation of the adjusting device, the adjusting device adjusts the mold profile according to the normal displacement deviation, and the mold supporting back support is connected to the mold profile by the angle sheet after adjustment of the mold profile. The design device and the design method of the adjustable composite-material mold provided by the invention realize the high accuracy of the mold profile through the profile adjustment. The method can be used in research and manufacture of a high-accuracy reflector in a remote sensing satellite and a communication satellite, can also applied in research and manufacture of a ground high-accuracy reflector, and satisfies demands of a high-accuracy reflector antenna mold with a low thermal expansion coefficient.

Description

technical field [0001] The invention relates to a mold design device and design method, in particular to an adjustable composite material mold design device and design method, which are used for the design of high-precision composite material molds and belong to the field of satellite antennas. Background technique [0002] The reflector antenna mold is a production tool for reflector antennas with certain shape, size and precision requirements. According to different mold materials, the antenna reflector antenna mold can be divided into metal mold and composite material mold. Metal molds include aluminum molds, cast iron molds and Invar molds; composite molds include carbon fiber composite molds and graphite molds. [0003] During the curing and molding process of the reflector antenna, the reflector is solidified and molded close to the mold surface, so the mold surface precision (RMS) is an important factor affecting the processing accuracy of the reflector surface. Sin...
