For up to 800mm carbon fiber shaft, the heat transfer more difficult, but we have overcome many difficulties, and finally completed a set of automatic transfer machine.
1) carbon fiber material: Carbon fiber is made from organic fibers by carbonization and graphitization treatment obtained microcrystalline graphite materials. Similar to the microstructure of carbon fiber artificial graphite is turbostratic graphite structure. A mechanical performance of new materials, steel accounted for less than 1 / 4, the tensile strength of carbon fiber resin composite materials are generally in 3500Mpa above, is 7-9 times that of steel, tensile elastic modulus of 230 ~ 430Gpa also high in steel. Therefore, the specific strength of CFRP material intensity and the ratio of the density can be achieved 2000Mpa / (g/cm3) above, the specific strength of A3 steel only 59Mpa / (g/cm3) about a specific modulus than steel. Higher than the strength of the material, the smaller the component weight, higher than the modulus, the greater is the stiffness, in this sense indicates that the carbon fiber has broad application prospects in engineering. Carbon fiber is a carbon content higher than 90% of the inorganic polymer fibers. In which the carbon content higher than 99% of said graphite fibers. Carbon fiber axial strength and high modulus, non-creep, fatigue resistance, good heat and electrical conductivity between the metallic and metal between the thermal expansion coefficient, good corrosion resistance, low density of fibers, X-ray transparent too good. But its poor impact resistance, easy to damage, under the action of the acid oxidation, and metal composite occurs when the metal carbide, cementite and electrochemical corrosion. Therefore, before use of carbon fiber surface treatment. Carbon fiber shaft with the use of its excellent fatigue resistance. Through the experiment, as long as the transfer film adhesive layer to make the necessary improvements, the transfer of carbon fiber can achieve good results.
2) transportation; trough the use of the usual storage device can be placed about 150 shaft. As the inherent speed of thermal transfer, automatic transfer machine speed can reach 1200 per hour, higher speed depends on the overall structure of the machine, but given the long shaft, high speed could mean the loss of stability .
3) fixtures; double-stick-type structure, which is slender cylinder for the structure of commonly used products.
