Method and apparatus for cutting flat tube |
摘要 |
<p>A continuously-fed flat tube is cut into sub tubes each having a given length. The flat tube has multiple ports therein. A pair of roller cutters are enabled to follow the flat tube at a zero relative speed between the roller cutters and the flat tube. The roller cutters 28 are moved across portions of the flat tube respectively to cut the flat tube while the roller cutters are enabled to follow the flat tube at the zero relative speed. At least one of the roller cutters enters the flat tube by a depth equal to or greater than a half of a distance between outer flat surfaces of the flat tube while the roller cutters are moved across the portions of the flat tube. <IMAGE></p> |
