Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a metal thin-walled piece cloth tape winding mould. Background Art

[0002] Tape winding is a composite material molding process, which generally refers to using epoxy resin or phenolic resin as the matrix and glass fiber or carbon fiber as the reinforcement. The fiber tape pre-impregnated with resin is evenly wound on the surface of the external metal thin-walled part through a winding head in a flat or oblique winding manner under certain tension, temperature and humidity conditions.

[0003] At present, the cloth tape winding mold includes a metal thin-walled part and a winding mandrel. The metal thin-walled part is sleeved on the outer circumference of the winding mandrel. The driving device drives the winding mandrel and drives the metal thin-walled part to rotate synchronously. The cloth tape is wound on the metal thin-walled part and solidified as a whole with the shell. The tension of the cloth tape and the pressure formed by the shrinkage of the resin during the curing process will cause the metal thin-walled part to deform or even buckle. Utility Model Content
