Method for prolonging service life of twist drill based on heat pipe phase changes
InactiveCN103537737AHigh heat transfer efficiencyReduce cutting temperatureTransportation and packagingTwist drillsHeat transfer efficiencyEngineering
The invention discloses an environment-friendly method for prolonging the service life of a twist drill based on heat pipe phase changes, so durability of a standard twist drill with a straight shank can be remarkably improved under a drilling especial for high-speed drilling machining condition. According to the method, a heat pipe theory and technology are brought in, heat pipe phase change heat transfer characteristics are made use of, cutting fluid is not adopted, and the cutting temperature of the main cutting edge and the cutting temperature of the chisel edge part of the twist drill are rapidly lowered with the help of a heat pipe to reduce the abrasion rate of the main cutting edge and the chisel edge part of the twist drill so that the purpose of prolonging the service life of the twist drill is achieved. Heat pipe phase change heat transferring is adopted in the method, so the heat pipe is higher than cutting fluid in heat transfer efficiency; the heat pipe technology is adopted, so the heat pipe is more environment-friendly than cutting fluid, and personal injuries to operation staff do not exist. In addition, the heat pipe adopted in the method is cheaper than the cutting fluid in market price, and therefore manufacturing cost of products of enterprises can be reduced.
