Problems solved by technology
[0002] Traditional electric poles generally have the disadvantages of bulkiness, perishability, corrosion or cracking, and short service life. Construction, transportation, operation and maintenance are difficult, and various safety hazards are prone to occur. With the development of new material technology and its preparation process, composite materials have been obtained In order to achieve rapid development, composite poles have the advantages of light weight, corrosion resistance, high strength, and longer life. They are low in maintenance costs and can withstand extreme weather conditions. They can be used in projects such as power transmission and distribution lines, communication lines, and communication towers. Great replacement for traditional wooden poles, reinforced concrete poles and iron towers
At present, composite material poles have been applied in transmission towers. However, there are still many key problems in the processing technology of composite tapered poles that have not been resolved, which may result in higher production costs, or lead to the strength and stiffness of the produced tapered poles. performance is not enough

Abstract
The invention discloses a machining method and system for a novel conical composite material electric pole. The method includes the steps that first, an electric pole mold core and necessary tool components are erected in a four-axis winding system, and glass fibers with an inner layer of adhesive and an outer layer of adhesive which are prepared according to a certain proportion and formulas are wound around the surface of the electric pole mold core; after being wound, the glass fibers are moved into an electric heating curing furnace together with the electric pole mold core to be cured and shaped; and after being shaped, the cured conical composite material electric pole product is moved into a cutting mold release machine together with the electric pole mold core, and with the ends cut off, the composite material electric pole is released from the electric pole mold core. The conical composite material electric pole manufactured through the method has the beneficial effects of being capable of achieving low-carbon environment protection, easy to transport and install due to the light weight, high in strength, long in service life, good in weather resistance, corrosion resistance and insulating performance, high in natural hazard resisting capacity and the like and can well replace traditional reinforced concrete electric poles and steel tube towers in the projects of power transmission and distribution lines, communication lines communication towers and the like.
