[0046] In this embodiment, two sets of third elastic assemblies 37 are installed, and the two sets of third elastic assemblies 37 are respectively located at both ends of the upper surface of the second wire-passing block 361.

During the corner cutting process, the inner wall of the inner ring 3421 presses the pressure head 371, which pushes the third floating block 363 so that the pressure post 372 moves toward the copper wire. The third floating block 363 presses against the copper wire, thereby achieving the purpose of the pressure post 372 fixing the copper wire. The inner wall of the inner ring 3421 has a path that protrudes outward along the radial direction of its center. When the corner cutting operation is completed, the rotating driven gear 342 moves the pressure head 371 into a path that protrudes outward from the inner ring 3421. Under the action of the second spring 373, the pressure post 372 moves away from the copper wire. The third floating block 363 no longer presses against the copper wire, allowing the copper wire to continue feeding and then perform the corner cutting operation at the next location.

The moving assembly 83 includes a third mounting plate 838 fixed to the fifth table 81 via a bolt, a second motor 8310 fixed to the third mounting plate 838 via a bolt, two fourth standing plates 837 installed on both sides of the second motor 8310, a second swing rod 832 connected to the fourth standing plate 837 via a bearing and a drive connecting rod 8312, and a second swing rod 832 connected to one end of the swing rod. the fourth upright plate 837 is fixed to a third mounting plate 838 with bolts; an axis rod 8311 is installed on one side of the second motor 8310 and is rotatably connected to the fourth upright plate 837; the axis rod 8311 is connected to the output shaft of the second motor 8310 and a drive connecting rod 8312 with a timing belt; and a fifth cylinder 839 located on the fifth table 81 is connected to the bottom of the storage block 835 with a bolt; Two second swing rods 832 are symmetrically installed, A sixth sliding rail is fixed to the opposing side of the fourth upright plate 837 via bolts, and a connecting slider 831 is slidably connected to the sixth sliding rail. The two connecting sliders 831 are slidably connected to the first lifting rod 834 and the second lifting rod 836 vertically. The accumulation assembly 82 includes a second fixed base 821 fixed to the fifth table 81 via a bolt, a second rotating disk 822 rotatably connected to the second fixed base 821, a third motor 825 connected to the center of the bottom of the second rotating disk 822, and two sets of clamping rods 824 fixed to the second rotating disk 822 via a bolt, each set of clamping rods 824 being divided into two pairs on the left and right, and a gap is left between each pair of frame rods for placing an I-shaped copper wire; A receiving block 823 is installed between the two pairs of clamping rods 824, and a U-shaped groove is opened on the side of the receiving block 823. The U-shaped groove of the receiving block 823 is slidably connected to the clamping rods 824, so that the receiving block 823 can slide vertically along the clamping rods 824. A sixth cylinder 826 abuts against the receiving block 823, and when the second turntable 822 rotates, the upper end of the sixth cylinder 826 is located below the second turntable 822. The third motor 825 is fixed to the second fixed base 821 via a bolt, When the I-shaped copper wires of the first lifting rod 834 and the second lifting rod 836 enter between the two clamping rods 824, the first lifting rod 834 and the second lifting rod 836 do not come into contact with the I-shaped copper wires inserted between the two clamping rods 824 when they move downward; In use, the second swing rod 832 rotates, causing the connecting slider 831 to slide away from the collecting assembly 82, so that the I-shaped copper wire at the upper end of the first lifting rod 834 and the second lifting rod 836 falls into the gap between one pair of clamping rods 824, and the other I-shaped copper wire is placed on the storage block 835. When the connecting slider 831 slides to the end of the sliding rail, the end of the first lifting rod 834 is located below the copper wire in the storage block 835, and the rear ends of the first lifting rod 834 and the second lifting rod 836 receive the I-shaped copper wire transported by the moving plate. The second swing rod 832 continues to rotate, transporting the copper wire back into the collecting assembly 82. When the I-shaped copper wire is first received, the sixth cylinder 826 pushes the receiving block 823 up to the upper end of the clamping rod 824 so that the I-shaped copper wire falls onto the receiving block 823. As the copper wire increases, the sixth cylinder 826 slowly contracts, causing the receiving block 823 to slowly move downward. When one set of clamping rods 824 cannot continue to collect the I-shaped copper wire, the third motor 825 rotates the second turntable 822, so that the set of clamping rods 824 that is not collecting the I-shaped copper wire continues to collect the copper wire. When the copper wire in the clamping rods 824 needs to be transferred, the sixth cylinder 826 pushes the receiving block 823 up, pushing the copper wire out of the clamping rods 824. When the second turntable 822 needs to rotate, the fifth cylinder 839 in the moving assembly 83 pulls the storage block 835 downward, and the connecting slider 831 also slides away from the collecting assembly 82, thus preventing the collected copper wires from being unable to rotate smoothly.
