| 简介 |
The present invention relates to a method for cutting a synthetic resin pipe which can cut a synthetic resin pipe (P) to a predetermined length. The method for cutting the synthetic resin pipe of the present invention comprises the steps of : heating a part (A) to be cut with an induction heater (41) or hot air of high temperature before cutting a synthetic resin pipe (P) sized after extrusion; and cutting the heated part (A) using a cutting blade or cutting means, such as a circular saw (43). The method for cutting the synthetic resin pipe according to the present invention can prevent a change in size of the outer diameter of the cut part (A) to thereby cut the synthetic resin pipe into a uniform size (outer diameter) because the part of the pipe to be cut is flash-heated and the heated part is cut, can produce synthetic resin pipes which are uniform in diameter and thickness after being cut because deformation in size of the outer diameter is prevented, and can enhance productivity because it does not need postprocess for correcting the size of the outer diameter of the synthetic resin pipe after cutting.(AA) TransferringCOPYRIGHT KIPO 2014 |
