Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber tube production curing furnaces, and particularly relates to a curing furnace with uniform heating. Background Art

[0002] The carbon fiber tube, also known as the carbon fiber tube and carbon tube, is made by pre-impregnating carbon fiber materials into styrene and polyester resin and then heating and curing by pultrusion. The carbon fiber coiled tube has the advantages of high strength, long life, corrosion resistance, light weight, low density, etc. It is widely used in roll shafts for industrial machinery, aerospace, medical, PC equipment rotating shafts and other mechanical equipment. The forming technology of the carbon fiber coiled tube has the following steps: material preparation → cutting → cloth attachment → coiling → winding → curing → demolding → tape removal → grinding → cutting → painting. Therefore, curing operation is required during the production of carbon fiber tubes, and the commonly used one in production is the curing furnace. Most common curing furnaces are heated by a single heat source inlet to raise the temperature inside the curing furnace, and then heat and cure the carbon fiber tube mold assembly. This results in a relatively higher temperature near the heat source outlet compared to other areas, causing uneven heating of the carbon fiber tube mold assembly during heating, making the curing quality of the carbon fiber tube mold assembly at different positions inconsistent and affecting the quality of the final carbon fiber tube product.
