[0024] In some embodiments, the collection groove 722 can collect and discharge the debris generated during drilling and cutting in advance. At the same time, by rotating the screw rod 726 counterclockwise to push the screw rod 726 out of the plug-in state with the groove and the plug plate 724, the collection frame 725 can be pulled to the lower end, thereby removing the collection frame 725 from the discharge seat 721, so as to facilitate the discharge and cleaning of the collected debris.

[0025] In the present application, the stacking mechanism 75 includes a discharge frame 751, a positioning rod 752, a support block 753, a rotating shaft 754, a connecting rod 755, a steel ball 756, and a lifting mechanism 757. The discharge frame 751 is connected to the right end of the discharge pipe 74. The left and right sides of the discharge frame 751 are relatively provided with movable chambers. The inside of the movable chamber is provided with a connecting rod 755. The connecting rod 755 is rotatably connected to the middle part of the rotating shaft 754. The lower end of the discharge frame 751 is provided with a lifting mechanism 757. The rotating shaft 754 is provided with two The connecting rod 755 is provided with a supporting block 753 along the front and rear sides of the connecting rod 755, and the middle part of the rotating shaft 754 is provided with a supporting block 753, the supporting block 753 is in contact with the bottom of the steel ball 756, the connecting rod 755 and the positioning rod 752 are provided in parallel with each other, and the front and rear ends of the connecting rod 755 are fixed to the active cavity, the positioning rod 752, the supporting block 753, the rotating shaft 754, the connecting rod 755, and the steel ball 756 mutually constitute a supporting structure, and the supporting structure is provided with six groups, two by two in a row, and a total of three rows are provided, along the row The interior of the discharge frame 751 is evenly distributed, and each column of the supporting structure can support a steel ball 756. The lifting mechanism 757 includes an arc block 7571, a push rod 7572, a compression spring 7573, a limit plate 7574, a slide bar 7575, a connecting block 7576, and a push block 7577. The push rod 7572 is slidably matched with the lower end of the interior of the discharge frame 751, the arc block 7571 is fixed to the top of the push rod 7572, the push rod 7572 runs through the middle of the compression spring 7573, and the compression spring 7573 and the limit plate The top of 7574 is fixed, the top of the compression spring 7573 is fixed to the discharge frame 751, the middle part of the limit plate 7574 is fixed to the push rod 7572, and sliding rods 7575 are arranged on the left and right sides of the top of the arc block 7571. The limit plate 7574 is fixed to the rear end of the connecting block 7576, and the connecting block 7576 is fixed to the rear end of the push block 7577. The cross-section of the push block 7577 is an L-shaped structure, and the front end of the push block 7577 is provided with anti-slip grooves to facilitate pushing the push block 7577 upward.

[0026] In some embodiments, the push block 7577 is pushed upward so that the push block 7577 drives the push rod 7572 to move upward through the connecting block 7576. When the push rod 7572 moves, the limit plate 7574 cooperates with the discharge frame 751 to press the compression spring 7573 to produce deformation and contraction. The push rod 7572 drives the arc block 7571 to push the steel ball 756 discharged to the discharge frame 751 upward. When the steel ball 756 is pushed upward, the support block 753 will swing upward, and then the thrust on the push block 7577 is released. The elastic potential energy of the deformation is restored by the compression spring 7573, driving the arc block 7571 to move downward and return to its original position, so that the next steel ball 756 is discharged to the arc block 7571. The top of the push block 7577 pushes the next steel ball 756. When the previous steel ball 756 loses the lifting force, the previous steel ball 756 moves down and the rotating shaft 754 is reset. The support block 753 supports the bottom of the previous steel ball 756 to prevent the previous steel ball 756 from moving down. The positioning rod 752 serves to limit the support block 753 to prevent the support block 753 from swinging too much. The reciprocating pushing of the push block 7577 can make the steel balls 756 rise one by one. The steel ball 756 at the lower end can also push the steel ball 756 at the upper end. The operator only needs to take the top steel balls 756 one by one, thereby increasing the efficiency of taking the steel balls 756.

[0027] In summary, when in use, a steel ball 756 is placed in advance in the pipe that needs to be pulled out, and then the pipe is placed in the positioning seat 3. At this time, the cylinder 1 4 drives the moving seat 5 to move downward to clamp and position the placed pipe. At the same time, the cylinder 2 9 is extended to push the pushing seat 10 to move toward the support frame 2, so that the push rod 11 is embedded in the pipe. The steel ball 756 is supported by the left and right push rods 11, so that the steel ball 756 is at the pulling hole of the pipe; The screw module 66 drives the cutter head seat 64 to feed one position to the front end, at which time the suction roller 69 is flush with the drill hole, and then the cylinder 3 63 is extended to make the suction roller 69 and the steel ball 756 be adsorbed, and at the same time the positioning roller 68 positions the pipe, and the cylinder 3 63 is contracted to pull the steel ball 756 out of the drill hole, so that the drill hole is subjected to the hole extraction and flanging treatment; When the steel ball 756 is separated from the inside of the pipe, the adsorption roller 69 releases the adsorption of the steel ball 756, so that the steel ball 756 falls onto the guide seat 71 and is discharged through the discharge groove 73. Then, the steel ball 756 is guided through the discharge pipe 74 and discharged into the stacking mechanism 75 for collection. After the hole pulling and flanging are completed, the screw module 66 drives the cutter head seat 64 to feed one position to the front end again, so that the shaping roller 610 is flush with the hole pulling and flanging, and then the cylinder three 63 drives the shaping roller 610 to move to the right end, and the burrs on the hole pulling and flanging are cut and smoothed by the shaping roller 610, thus completing the whole set of hole pulling operations.
