Claims (1)

[Scope of utility model registration request] a feed device that feeds a plurality of pipes simultaneously in parallel; a stopper portion that blocks the tips of the plurality of pipes fed from the feed device;
a clamp device that clamps one end of each pipe stopped by the stopper portion; a cutter portion that cuts each pipe clamped by the clamp device;
In a pipe bending machine equipped with a bending unit section that simultaneously bends the end portions of each pipe cut by the cutter section and protruding from the clamp device into a U-pipe, the clamp device separates each pipe end portion. The stopper device is composed of a plurality of clamp dies to be clamped and a plurality of push drive bodies connected to these clamp dies, and the stopper device stops each pipe separately and separately sends a drive signal to each push drive body of the clamp device. The pipe bending machine is characterized in that the feed device continues feeding until the clamp device finishes clamping all the pipes.
