The invention discloses an automatic fusing cutting machine for stainless steel woven polytetrafluoroethylene tubes. The machine comprises a wire feeding and pressing module, a belt wheel wire pressing module, a guiding wire pressing module and a fusing module in sequence from right to left. The fusing module comprises a left upper pressing block, a right upper pressing block, a left lower pressing block and a right lower pressing block, wherein the left upper pressing block and the right upper pressing block can slide vertically and move horizontally; the left lower pressing block and the right lower pressing block can move horizontally; the pipeline passing workstation positions among the left upper pressing block, the right upper pressing block, the left lower pressing block and the right lower pressing block are each provided with a dismountable fusing conductive copper knife installed vertically; a vertically installed saw blade is installed in front of the pipeline passing workstation position of the fusing module. For the characteristics of woven hoses, through the reasonable structural improvement, especially the design of combination of the pressing blocks and the saw blade, steel wire layers of the woven hoses are fused through the combination of the pressing blocks, then the saw blade cuts off tubes on the inner layers, the woven hoses are pulled broken when the combination of the pressing blocks is in a heating state, and therefore the steel wires do not explode without external force when fused, and it is ensured that the fracture surfaces after fusing are tidier and smoother.
