Rotary heating type composite propeller curing oven

Abstract

The invention provides a rotary heating type composite propeller curing oven comprising an oven body, a heating mechanism and a mold holding mechanism. The first end of a rotary shaft is rotationally connected with the first side wall of the oven body. The second end of the rotary shaft penetrates through the geometric centers of a first installing ring and a second installing ring sequentially to be rotationally connected with the second side wall of the oven body. The inner side of the first installing ring is fixedly connected with the rotary shaft through a plurality of first connecting rods. The inner side of the second installing ring is fixedly connected with the rotary shaft through a plurality of second connecting rods. The first ends of a plurality of support shafts are all connected with the first installing ring, and the second ends of the multiple support shafts are all connected with the second installing ring. A plurality of mold holding frames are hinged to the multiple support shafts correspondingly. A first heating disc is located on the side, away from the second installing ring, of the first installing ring and is rotationally installed on the rotary shaft. The two ends of an air conduit are connected with the first heating disc and a second heating disc correspondingly. The rotary heating type composite propeller curing oven can meet the requirement for temperature in the forming process of a composite propeller, cost is low, and in-oven temperature is uniform.

Description

technical field [0001] The invention relates to a curing furnace, in particular to a rotary heating type composite material propeller curing furnace. Background technique [0002] The propeller is a key part of the power machinery in a helicopter or other small aircraft. Compared with traditional metal propellers, composite propellers have many advantages such as light weight, high rigidity, low vibration, strong weather resistance and flexible design. There is a large temperature difference inside the existing composite material propeller curing furnace, and the temperature difference between the upper, lower, left and right sides of the furnace is relatively large, especially after being placed in the propeller mold, there is a large temperature difference between the upper and lower molds of the mold, which seriously affects the composite material. The quality of the material propeller. Contents of the invention [0003] Based on the technical problems existing in the...
