The two support blocks are respectively slidably connected to the top and bottom of the track 612. A first stop block 618 is fixedly connected to the hinge block 66, and a second stop block 619 is fixedly connected to the side plate 68.The top of the second stop block 619 contacts the bottom of the first stop block 618.

[0026] Working principle: Place the copper bar on the placement seat 62 and the rotating plate 67. Start the first electric push rod 63. The first electric push rod 63 drives the pressing plate 64 to descend to fix one end of the copper bar. Then start the third electric push rod 616. Under the action of the first stop block 618 and the second stop block 619, the third electric push rod 616 drives the rotating disk 67 to move through the hinged rod 617, so that the rotation axis of the rotating disk 67 is directly below the position where the copper bar needs to be bent. Then start the second electric push rod 610 to drive the fixed roller 611 to descend to fix the other end of the copper bar. Start the driving motor 2 to drive the rotating rod 3 to rotate, thereby driving the gear 4 to rotate. The rotation of the gear 4 drives the internal gear disk 5 to rotate, thereby driving the copper bar on the placement seat 62 to rotate. When the placement seat 62 rotates, it drives the moving block 614 to descend under the action of the bending part 6121 of the track 612, thereby driving the bottom end of the hinged rod 617 to descend through the third electric push rod 616, and then driving the rotating plate 67 to rotate downward through the hinged rod 617, and bending the copper bar through the fixed roller 611. When the moving block 614 descends to the lowest end, the bending of the copper bar is completed. At this time, the moving block 614 enters the horizontal part 6122. During the movement of the moving block in the horizontal part 6122, the bent copper bar is fixed in terms of angle, making the bending of the copper bar more stable. At the same time, the rotation of the gear 4 drives the rotating block 75 to move in a circular motion, and drives the moving frame 74 to reciprocate under the action of the limiting rod 72 and the limiting frame 73, thereby driving the arc-shaped plate 76 to reciprocate, so that the elastic knocking block 77 on the arc-shaped plate 76 knocks on the base 61, thereby generating vibration. Through the vibration, the stress distribution generated by the bending of the copper bar is more uniform, improving the bending effect of the copper bar. When the moving block 614 moves to the hinge of the horizontal part 6122 and the recovery part 6123, the operator starts the first electric push rod 63 to drive the pressing plate 64 to rise, then removes the bolts of the top plate 69 and opens the top plate 69 to remove the bent copper bar. After removal, fix the top plate 69 with bolts again. When the moving block 614 moves into the recovery part 6123, the moving block 614 will rise, thereby driving the rotating plate 67 to turn upward through the hinged rod 617 until it is in a horizontal state.

[0027] Please refer to Figures 1-10, on the basis of the above embodiments, in another embodiment of the present invention, preferably, the drilling mechanism 8 includes a bracket 81 and a drilling machine 82. The bracket 81 is fixedly installed on the top of the machine body 1, and the drilling machine 82 is installed on the bracket 81. The drilling mechanism 8 further includes a drilling groove 83, a discharge groove 84, an annular groove 85, a push plate 86, a connection groove 87, and a collection box 88. The drilling groove 83 is opened on the top of the placement seat 62, the discharge groove 84 is opened on the top of the internal gear disk 5 and communicated with the bottom of the drilling groove 83, the annular groove 85 is fixedly connected to the top of the machine body 1, and the annular groove 85 is rotatably connected to the bottom of the internal gear disk 5. The push plate 86 is fixedly connected to the bottom of the internal gear disk 5 and slidably connected to the inner wall of the annular groove 85. The connection groove 87 is opened on the top of the machine body 1 and communicated with the bottom of the annular groove 85. The collection box 88 is arranged on the machine body 1. A cover plate 89 is fixedly sleeved on the outer wall of the bracket 81, and the cover plate 89 is located above the internal gear disk 5.

[0028] Working principle: When the placement seat 62 rotates to the lower part of the drilling machine 82, it stops rotating. At this time, the copper bar is drilled by the drilling machine 82. The waste chips generated by drilling enter the discharge groove 84 through the drilling groove 83, and then enter the annular groove 85 through the discharge groove 84. When the internal gear disk 5 moves later, it will drive the push plate 86 to move. The waste chips are pushed into the connection groove 87 by the push plate 86, and then slide into the collection box 88 through the connection groove 87 for collection.

[0029] It should be noted that after the driving motor 2 drives the internal gear disk 5 to rotate one-quarter of a circle, it will stop. At this time, the operator at the front station installs a new copper bar on the placement seat 62, the drilling machine 82 on the right drills the copper bar, and the operator at the left station removes the bent and drilled copper bar, so as to achieve continuous processing and improve work efficiency.

The above description is only the preferred embodiment of the present invention.

Each component not clearly defined in this embodiment can be implemented by existing technologies.
