Description

Technical Field

[0001] This utility model relates to the field of wire EDM pipe cutting machine technology, specifically a pipe cutting support frame for wire EDM pipe cutting machine. Background Technology

[0002] Currently, in order to improve efficiency, wire EDM tube cutting processes aim to process as many tubes as possible at once. Since the tubes are relatively long, generally longer than 2 meters, the clamping part is relatively short during processing, but there are many tubes to process. As a result, the unclamped part will spread out and the shape will not be fixed. This will cause inconsistent feeding lengths during subsequent feeding, which will affect the accuracy of tube processing. Utility Model Content

The size of the prismatic cavity can be adjusted to clamp tubes 5 of different sizes and quantities. When the rollers 4 rotate, the rolling friction of the tubes 5 to be processed is very small, which greatly improves the feeding accuracy of the tubes 5 to be processed. The limiting screw 6 can adjust the size of the prismatic cavity formed by the multiple rollers 4. The clamping force of the tubes 5 to be processed is adjusted by the tension spring 9. During adjustment, the upper pressure plate 2, the fixed seats 3 and rollers 4 fixed on the upper pressure plate 2 can move up and down along the guide post 7 and guide sleeve 8.
