Abstract

The invention belongs to the technical field of technological equipment designing and manufacturing, and particularly relates to a skin stretch forming die and a manufacturing method thereof. The skinstretch forming die comprises a wooden structure frame, an epoxy resin-talcum powder surface and an epoxy resin-glass bead filling body; and the wooden structure frame is arranged at the periphery and the bottom face of the skin stretch forming die, the epoxy resin-talcum powder surface is arranged on the top face of the skin stretch forming die, the wooden structure frame and the epoxy resin-talcum powder surface form a hollow space, and the hollow space is filled with the epoxy resin-glass bead filling body. According to the skin stretch forming die and a manufacturing method thereof, the technological operation processes are simple, filling material sources are wide, the relative cost is low, the relative weight is low, and machining and using are convenient in the skin part stretch forming process.

Description

technical field [0001] The invention belongs to the technical field of process equipment design and manufacture, and in particular relates to a skin stretch forming mold and a manufacturing method thereof. Background technique [0002] The design and manufacture of skin stretch forming die is one of the key technologies in aviation process equipment. At present, epoxy sand (epoxy resin + quartz sand) is usually used as the carcass material in the manufacture of aircraft skin stretch forming molds. The weight of the stretch mold after it is filled is too large, and the production cost increases. Transportation, storage and storage bring a series of difficulties. Therefore, it is of great theoretical significance and practical value to develop a skin stretch forming die made of a new material with good strength and rigidity, low cost and light weight. Contents of the invention [0003] The purpose of the present invention is to provide a skin stretching mold made of a new ...
