Abstract

The invention provides a wind power blade male die with a heating system. The wind power blade male die with the heating system is composed of a regular part and an irregular part arranged on a chassis. The irregular part is formed by surrounding of a curved surface and a plane, and comprises a laminated board, a foam layer, a first heating pipe and a first sealing layer. The regular part is formed by surrounding of a plane, and comprises a sectioned board, a second heating pipe and a second sealing layer. The invention also provides a molding method of the wind power blade male die with the heating system. According to the wind power blade male die with the heating system, when a female mold is duplicated, epoxy resin, as the base material of the female mold, can be cured by the heating system, thereby avoiding the uneven heating due to the hot air blown by an air heater and the heating of a high-power electric appliance, and preventing the deformation due to the uneven curing in thecuring molding process of the female mold to cause the problem of quality defects.

Description

technical field [0001] The invention relates to a male mold, in particular to a wind power blade male mold with a heating system and a forming method thereof. Background technique [0002] With the development of new energy development, more and more attention has been paid to wind power generation. With the steady increase in the total number of wind power generating units, the demand for wind power blades is also gradually increasing. Wind turbine blades are one of the core components of wind turbines, and their formed structure directly affects the service life of wind turbine blades and the utilization rate of wind energy of wind turbines. [0003] The forming of wind turbine blades is usually made by turning the female mold, and the female mold is made by turning the male mold. It is extremely important to keep the shape and structure of the mold stable during the turning process. When the female mold is turned from the male mold, the base material resin of the female ...
