The working principle of the invention is as follows:

feeding: the corrugated pipe 6 is conveyed into the feeding bin by the conveyor belt 5 in the conveying bin 1, and when the corrugated pipe 6 is sensed by the first sensor 7, the conveyor belt 5 stops conveying; when the corrugated pipe 6 is not sensed by the first sensor 7, the conveyor belt 5 continues to convey;

feeding: when the bending machine is in an initial state (a signal sensor at the lower end of a second air cylinder 15 is in a working state), the second sensor 8 senses the corrugated pipe 6, a first air cylinder 9 on the left side of the feeding bin drives a first push rod 10 and a feeder 12 to operate, the feeder 12 conveys the corrugated pipe 6 into the elbow mechanism 3, the latter corrugated pipe 6 is rolled onto a supporting plate 11, when the feeder 12 is retracted, the corrugated pipe 6 on the supporting plate 11 falls into the feeder 12 in a following manner, the filling of the feeder 12 is completed, and the feeding time is shortened;

bending: when the corrugated pipe 6 is fed above the movable clamping block 29 by the feeder 12, the third cylinder 27 operates to push the third push rod 28 to move the movable clamping block 29 upwards, the movable clamping block 29 and the fixed clamping block 32 clamp the corrugated pipe 6, then the fourth cylinder 30 operates to push the connecting block 31 on the fourth push rod 33 to move the fixed bottom plate 26 inwards, the movable clamping block 29 and the fixed clamping block 32 are pushed to the corrugated part of the corrugated pipe 6, the second cylinder 15 operates to push the second push rod 16 to move the sliding block 18 upwards, the sliding block 18 drives the transmission shaft 23 to move, and the transmission shaft 23 drives the connecting rod 24 and the movable plate 25 to move upwards, so that the corrugated pipe 6 is bent to a set angle;

resetting: when the sensor at the upper end of the second cylinder 15 judges that the corrugated pipe 6 does not rebound after being bent and formed within 0.2 second delay, the fourth cylinder 30 operates to withdraw the fourth push rod 33 and the connecting block 31, the third cylinder 27 operates to withdraw the third push rod 28 to drive the movable clamping block 29 to move downwards, the bent corrugated pipe 6 falls into the hopper 22 and then falls onto the packaging workbench 4 through the discharge port 21, the second cylinder 15 operates to withdraw the second push rod 16 to drive the sliding block 18 to move downwards, the sliding block 18 drives the transmission shaft 23 to move, the transmission shaft 23 drives the connecting rod 24 and the movable plate 25 to move downwards to an initial position (the signal sensor at the lower end of the second cylinder 15 is in a working state), and the corrugated pipe 6 is sequentially and circularly bent.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many variations or modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
