A second motor 562 is fixedly provided on one side of this vertical plate 56. The output end of the second motor 562 is fixedly connected with the axis of the driving wheel 561 to control the rotation of the driving wheel 561.

[0060] A V-shaped block 57 is rotatably arranged above the driving wheel 561 on the vertical plate 56. One end of the V-shaped block 57 is fixedly connected with a sliding shaft 58, and the other end is fixedly connected with a pressing roller 59. The sliding shaft 58 is located above the pressing roller 59. The sliding shaft 58 moves under the action of an external force, driving the V-shaped block 57 to rotate, thereby controlling the pressing roller 59 to move downward.

[0061] As shown Figures 5 - 8 in the figure, the cutting part 3 is fixedly installed on the machine table 1, and the cutting part 3 is fixedly connected to the side wall of a molding machine 2. A T-shaped seat 31 is fixedly installed inside the cutting part 3. A wire groove 32 is formed on the T-shaped seat 31. Support seats 33 are fixedly arranged on both sides of the wire groove 32 on the T-shaped seat 31. A clamping groove is formed on the support seat 33 for supporting and fixing the pressure roller 59.

[0069] When the swing rod 501 on the wire member 5 drives the round shaft 502 to move, the steering rod 54 rotates, moving the connecting wire on the vertical plate 56 into the housing 21. The connecting wire extending from the wire member 5 is clamped and fixed by the first pneumatic clamp 25. Then, the second pneumatic clamp 222 moves away from the material guiding seat 213 in a translation manner, and then clamps and moves the cut insulating sleeve on the material guiding seat 213, so that the insulating sleeve moves and is inserted into the end of the connecting wire, and the end of the connecting wire with the inserted insulating sleeve is clamped by the third pneumatic clamp 24.

[0072] When the jaw 241 moves into the opening groove 216, the ejector pin 217 pushes the slide bar 27, moving the moving plate 271 out of the moving groove 244, so that the blocking bar 272 is located below the connecting wire already fitted with the insulating sleeve. Then, the cylinder two 28 drives the pressing rod 29 to move downward. The groove 291 is clamped with the end of the connecting wire. By pressing the connecting wire with the pressing rod 29, the end of the connecting wire abuts against the blocking bar 272. With the cooperation of the blocking bar 272 and the pressing rod 29, the end of the connecting wire is bent. After the pressing rod 29 moves downward, it can move into the through groove 219 to accommodate the bent end of the connecting wire and the pressing rod 29. At the same time, the through groove 219 accommodates the pressing rod 29, which can ensure the machining accuracy of the pressing rod 29.

The output end of the motor six 470 is fixedly connected with one end of the supporting rod 48. The motor six 470 drives the supporting rod 48 to rotate, so that the other end of the supporting rod 48 is clamped into the other end of the U-shaped block 47. After the supporting rod 48 is in a horizontal state, it can support the connecting wire.

[0076] The U-shaped block 47 is translated by the lead screw 445, and the supporting rod 48 is translated to fix one end of the connecting wire after being formed and processed below the arc-shaped block 443, straightening the connecting wire, avoiding the connecting wire from sagging and bending, and at the same time preventing the connecting wire from interfering with the normal processing operation. The pneumatic clamp four 442 clamps the unprocessed end of the connecting wire and sends the unprocessed end of the connecting wire into another forming machine 2 for the same installation of the insulating sleeve and bending processing of the connecting wire.

[0077] On the side of the drive shaft 42 away from the cutting member 3, a third cylinder 46 is fixedly provided. The output end of the third cylinder 46 is fixedly connected to a right-angle block 49. An inclined slot 491 is provided on the right-angle block 49. The right-angle block 49 is located below the horizontal shaft 45. The horizontal shaft 45 slides within the inclined slot 491. By driving the third cylinder 46, the right-angle block 49 is controlled to move upward. By moving the right-angle block 49 upward, the horizontal shaft 45 is moved, causing the moving rod 44 to move away from the cutting member 3. At this time, the third spring 444 is in a compressed state. Conversely, when the right-angle block 49 moves downward, the third spring 444 releases its elastic force, causing the moving rod 44 to move in the reverse direction.

[0078] In this embodiment, the models of the first pneumatic clamp 25, the second pneumatic clamp 222, and the third pneumatic clamp 24 all adopt DESTACO two-finger pneumatic grippers, and the models of the first slide 55 and the second slide 22 both adopt FSL80 dust-proof and waterproof ball screw linear modules.

[0079] A method for preparing the connecting wire of a high and low voltage switch cabinet, the preparation method includes the following steps:

[0080] S1. The wire feeder 6 is used to convey the raw material of the connecting wire, and the connecting wire is output from the wire conduit 52 and the wire output holes on the vertical plate 56.

[0081] S2. The connecting wire is input onto the T-shaped seat 31, and the connecting wire is skinned by the wire stripping knife 35. Then, the steering rod 54 is rotated to move the connecting wire into a forming machine 2 for covering with an insulating sleeve and end bending operations.

[0082] S3. The steering rod 54 is reset, and the bent connecting wire is conveyed to the wire moving member 4. The fourth pneumatic clamp 442 on the wire moving member 4 clamps and fixes the connecting wire, and the wire stripping knife 35 is used to cut the connecting wire.

[0083] S4. The wire moving member 4 is used to send the just-cut end of the connecting wire into another forming machine 2 for covering with an insulating sleeve and end bending operations.

[0084] S5. After the wire moving member 4 moves the connecting wire out of the forming machine 2, the fourth pneumatic clamp 442 releases the connecting wire, and the formed connecting wire of the high and low voltage switch cabinet automatically falls, completing the blanking.

[0085] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
