Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of demolding equipment, and particularly relates to a composite material cylinder demolding machine. BACKGROUND

[0002] The fourth type of structural material, fiber-reinforced composite material, has been used in large-scale industrial applications for more than 60 years after metals, ceramics and polymers. Because fiber-reinforced composite material has the characteristics of light weight, high strength and corrosion resistance, carbon fiber winding forming has become one of the important forming processes in carbon fiber composite material forming. Then, the fiber winding product is cured and demolded to form a carbon fiber cylinder, a sphere or other rotary body product. However, it is difficult to separate the mold during demolding, mainly because the outer surface of the mold needs to be wrapped with a demolding cloth during the winding process of some rotary winding products. The outer surface of the demolding cloth is wrapped with a rubber part, and then the outer surface of the rubber part is wound with carbon fiber. Then, the fiber winding product is obtained after curing. However, the mold and the outer surface of the demolding cloth are separated from the fiber winding product during demolding. Because the friction between the demolding cloth and the rubber part is particularly large during demolding, it is very difficult to demold at this time.

[0003] The existing composite material cylinder demolding device cannot clamp the cylinder to ensure the integrity of the composite material cylinder during demolding, cannot ensure the coaxiality between the core mold and the demolding ring, needs to continuously adjust the positions of the device and the cylinder before formal demolding, and is complicated to operate. Because the telescopic rod drives the core mold to pull out the core mold from the composite material cylinder, the length of the entire demolding device is at least three times the length of the core mold, and the land area is large. Because the core mold is not fixed, the composite material cylinder is not convenient to fix, and the use of oil cylinders, motors and the like as power sources has high cost and complicated operation. In order to separate the core mold and the composite material cylinder, the demolding ring with a diameter smaller than that of the cylinder and larger than that of the core mold is used to separate the core mold and the composite material cylinder. Because the wall thickness of the composite material cylinder is only 2-3 mm, a large centering property is required between the baffle and the composite material cylinder, so that the cylinder and the core mold can be correctly separated.

[0004] Therefore, a composite material mold demolding device is needed to solve the problems in the actual production process. SUMMARY
