Abstract

The invention relates to an auxiliary heating device for the post-curing of a die assembly for wind turbine blade production, comprising an air heater arranged at the root end of a web plate; the air heater is connected with a first heating pipe, a second heating pipe and a third heating pipe; the first heating pipe, the second heating pipe and the third heating pipe pass through an opening of a root end baffle arranged at the root end of the web plate; the first heating pipe is arranged at the rear of the root end of the web plate, and the front end of the first heating pipe is 0.9-1.1m away from the root end of the web plate; the second heating pipe is arranged above the root end of the web plate, and the front end of the second heating pipe is 5-7m away from the root end of the web plate; and the third heating pipe is arranged below the root end of the web plate, and the front end of the third heating pipe is 2-3m away from the root end of the web plate. The auxiliary heating device has the beneficial effects that a curing effect can still be achieved within shorter time under the condition that the die temperature is not changed, and the post-curing time can be shortened from 8.5h at present to 7.5h.

Description

technical field [0001] The invention relates to a heating device, in particular to an auxiliary heating device for curing after mold closing for the production of wind power blades. Background technique [0002] At present, most blade designs use glass fiber reinforced epoxy resin as their main material, and epoxy adhesive is used for bonding. The post-curing quality of epoxy resin and adhesive has a decisive impact on product quality. [0003] When the adhesive reaches the basic curing performance, the Tg (glass transition temperature) should be above 65°C. The Tg of the existing adhesive has reached the requirement after 4 hours of post-curing at 70°C. As time increases, the Tg value becomes larger and larger. [0004] But following the post-cure process of existing blades, it can be seen that the Tg of the product is far from meeting the requirements until the end of the heating program. [0005] Check the reason, mainly because the temperature in the blade is not enou...
