A feeding mechanism 1 is arranged on the frame 16, and a collecting mechanism 2 is arranged in front of the feeding mechanism 1. After the cylindrical tube is fed from the feeding mechanism 1, the feeding mechanism 1 enters the collecting mechanism 2, and the collecting mechanism 2 arranges and aligns the cylindrical tube. A positioning mechanism 5 is arranged on one side of the collecting mechanism 2, and a transfer mechanism 6 is arranged on the other side of the collecting mechanism 2. The positioning mechanism 5 can identify the cylindrical tube. The welding gap of the cylindrical tube is rotated by the material transfer mechanism 6 to avoid the welding gap in the bending direction. The bending mechanism 3 and the punching mechanism are sequentially arranged on the frame 2 17 in front of the collecting mechanism 2, and a transfer mechanism 7 for material transfer is arranged on one side of the frame 1 16 and the frame 2 17. The transfer mechanism 7 transfers the sorted cylindrical tube to the bending mechanism 3 for bending processing, and then transfers the bent cylindrical tube to the punching mechanism for punching, and then unloads the cylindrical tube with holes.

[0054] like Figures 2 to 4 As shown, the feeding mechanism 1 includes a material storage rack, which includes a relatively arranged fixed plate 105, on which a second support plate 106 is arranged, and the cylindrical tube is placed in the material storage rack and supported by the second support plate 106, and the second support plate 106 is arranged in an inclined shape, so that the cylindrical tube can naturally slide on the second support plate 106, and a conveyor belt 101 is arranged in front of the material storage rack, and a trough body 102 for placing the cylindrical tube is arranged on the conveyor belt 101, and the cylindrical tube naturally slides from the second support plate 106 into the trough body 102 and is transported by the conveyor belt 101, and a support plate 103 is arranged at the outlet end of the conveyor belt 101, and the support plate 103 is arranged in an inclined shape, and a stopper 104 is arranged on the support plate 103, and the cylindrical tube passes through the conveyor belt 101. The conveyor delivers the cylindrical pipe to the outlet end, and the cylindrical pipe naturally falls from the trough body 102 onto the support plate 103, and the blocking rod 104 blocks the cylindrical pipe to prevent it from continuing to slide down; a slide rail 107 is arranged on the frame 16, a slider 108 is arranged on the slide rail 107, a fixed plate 105 is arranged on the slider 108, and a driving component 109 for driving the fixed plates 105 to move closer to or away from each other is arranged on the frame 16. The driving component 109 drives the fixed plates 105 to move on the slide rail 107, so that the fixed plates 105 move closer to or away from each other. The driving component 109 is arranged as a hand wheel, and the distance between the fixed plates 105 can be increased or reduced by rotating the hand wheel to adapt to cylindrical pipes of different lengths.

[0055] like Figure 1 , Figures 4 to 7As shown, the material collecting mechanism 2 includes two relatively arranged fixed plates 201, a feeding carriage 202 and a driving component 203 for driving the feeding carriage 202 to move are arranged on the frame 16 between the two fixed plates 201, the driving component 203 makes the feeding carriage 202 move forward and backward, a pallet 3 204 and a pallet 4 205 are arranged above the feeding carriage 202, a connecting component is arranged between the pallet 3 204 and the pallet 4 205, the connecting component is arranged as a fixing rod, the fixing rod fixes the pallet 3 204 and the pallet 4 205, and a driving pallet 3 204 longitudinally drives the feeding carriage 202.

Since the pallet three 204 and the pallet four 205 are fixedly connected, when the driving component two 203 drives the feed slide plate 1 202 to move forward and backward, it will drive the pallet three 204 and the pallet four 205 to move synchronously at the same time. When the driving component three 206 drives the pallet three 204 to move longitudinally, it will drive the pallet four 205 to move longitudinally synchronously.

At this time, the groove four 212 is located below the pallet one 103, the groove five 213 is located below the groove one 207, and the groove six 214 is located below the groove two 208.

The groove four 212 lifts up the cylindrical tube on the pallet one 103, the groove five 213 lifts up the cylindrical tube on the groove one 207, and the groove six 214 lifts up the cylindrical tube on the groove two 208. Then the driving component two 203 and the driving component three 206 work respectively to put the cylindrical tubes on the groove four 212, the groove five 213 and the groove six 214 on the groove one 207, the groove two 208 and the groove three 209 respectively, so as to complete the collection by this reciprocating operation.

When the transverse slide 1 601 moves, the push plate 604 can push the cylindrical tube until the other end of the cylindrical tube contacts the baffle 502, so that the cylindrical tube on the groove 3 209 is neatly placed for easy transfer.

[0058] like Figure 1 , Fig.11 , Fig.13 and Fig.14 As shown, a clamp 2 8 for fixing the cylindrical pipe is arranged on the frame 16, and the clamp 2 8 includes an upper clamping die 3 801 and a lower clamping die 3 802 which are arranged opposite to each other. The upper clamping die 3 801 is driven by a driving component 13 803 and is clamped in cooperation with the lower clamping die 3 802.

[0059] The bending mechanism 3 is arranged in two groups and placed in a mirror-symmetrical manner. The two groups of bending mechanisms 3 placed in a mirror-symmetrical manner are named as an integral bending device one. In this way, the cylindrical tube can be bent symmetrically and the cylindrical tube can be bent into a U shape. When the length of the cylindrical tube is too long or too short, the driving component six 307 can simultaneously drive the two groups of bending mechanisms to move away from or closer to each other, so as to determine the bending position of the cylindrical tube, so as to adapt to cylindrical tubes of different lengths.

[0060] The bending mechanism 3 in the integral bending device 1 includes a transverse slide 2 301 arranged on the frame 2 17, and a driving component 6 307 for driving the transverse slide 2 301 is arranged on the frame 2 17.
