Description

Technical Field

[0001] This invention relates to the field of cable manufacturing and processing, and more specifically to a wire cutting device for live conductors. Background Technology

[0002] With the rapid development of industries such as power and communications, wires and cables, as an important component of infrastructure, are widely used in various high and low voltage power transmission, communication lines, control systems, and other fields. In the production and maintenance of cables, binding wire (i.e., metal wire used to bind and reinforce the cable structure) plays a crucial role. The cutting process of the binding wire is critical to the overall structural stability of the cable and subsequent processing. Traditional cutting devices have shortcomings in cutting speed, precision, and adaptability to binding wire materials. Therefore, developing a device capable of safely, efficiently, and accurately cutting the binding wire of live conductors is of significant practical importance for improving the efficiency of cable production and maintenance, ensuring operator safety, and reducing the technical difficulty of the cutting process. Summary of the Invention

[0003] The purpose of this invention is to provide a wire-binding cutting device for live conductors. In view of the shortcomings of the prior art, this invention provides a wire-binding cutting device for live conductors. Through innovative design, it can effectively solve the problems of safety, accuracy and efficiency in the process of cutting wire-binding cables.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wire-binding cutting device for live conductors, comprising a wire-binding cutting assembly, a conductor clamping assembly, and a wire-binding loop removal assembly.

[0005] The wire clamp docking assembly includes a robotic arm connector, a connector fitting, a clamp guide rail mounting plate, a clamp guide rail, a clamp slider, a wire binding and loop removal assembly connecting plate, a wire binding and cutting assembly fixing tripod, a wire binding and cutting assembly mounting plate, a clamp drive motor fixing housing, a clamp drive motor, a single diaphragm coupling, a wire binding and loop removal assembly mounting base, a lead screw locking nut, a clamp drive lead screw, and a clamp drive lead screw nut.

[0006] The wire cutting assembly includes a left-side cutting mechanism and a right-side cutting structure. The right-side cutting structure is the same as the left-side cutting structure and is symmetrically mounted on the wire cutting assembly mounting plate.

[0007] The left-side cutting mechanism includes a cutter drive motor mounting housing, a cutter drive motor, a cutter drive motor output flange, a lower right gripper, a cutter mounting bracket, a cutter, a cutter drive slider, a cutter drive screw nut, a cutter drive screw nut seat, a cutter drive guide rail, a cutter drive screw, and a cutter drive screw support seat.

[0008] The wire binding and de-looping assembly includes a de-looping drive motor output flange, a de-looping drive motor, a de-looping drive motor mounting housing, a single diaphragm coupling, an upper left gripper, a de-looping pusher preload spring, a de-looping pusher fixing frame, an auxiliary roller, a de-looping pusher, a de-looping drive screw, a de-looping auxiliary optical shaft, an annular gear, a single bearing seat, an upper right gripper, a pusher slider, a pusher guide rail, a preload spring upper fixing seat, a de-looping drive screw nut seat, a de-looping drive screw nut, a wire binding and de-looping assembly mounting plate, and a double bearing seat.

[0009] One end of the robotic arm connector is fixedly connected to the end of the external robotic arm, and the other end is connected to the connector connector. The connector connector is connected to the wire binding and loop removal assembly mounting base. The clamp drive screw nut is fixed on the wire binding and loop removal assembly mounting base. Therefore, when the clamp drive motor rotates and drives the clamp drive screw to rotate, the clamp drive screw nut is the fixed end. The clamp drive motor and the connected wire binding and cutting assembly move up and down to clamp the wire and fix the wire in the upper and lower pairs of clamping claw slots.

[0010] The de-ring drive motor transmits power to the de-ring drive screw, causing the de-ring pusher to move horizontally. The de-ring pusher has an arc-shaped blade to prevent the pusher from separating from the wire due to horizontal bending, which would prevent it from pushing the cut wire loop. The de-ring pusher pre-compression spring provides pre-pressure to the pusher, ensuring it is in close contact with the upper surface of the wire, preventing the pusher from separating from the wire due to vertical bending, which would prevent it from pushing the cut wire loop. The de-ring drive screw rotates, causing the de-ring pusher to move horizontally and push the cut wire loop onto the ring teeth on the right side.

[0011] The cutter drive motor transmits power to the cutter drive screw, causing the cutters on both sides to move horizontally. The clamp drive motor rotates, driving the wire cutting assembly to move upward, clamping the wire in the jaw slots on both sides. The cutter fixing frame has slots to facilitate the adjustment of the cutter height, so that the upper surface of the cutter is tangent to the lower part of the wire while the wire is clamped. The wire is cut when the horizontal distance between the blades on both sides is zero.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The cutting device of the present invention has wide adaptability and can handle cable binding wires of different specifications and types, including copper wire, aluminum wire and other metal materials. It can efficiently cut high-voltage cables, low-voltage cables and communication cables, avoiding the problem of poor cutting effect caused by poor adaptability in traditional equipment.

[0013] 2. The device of the present invention is simple in design and suitable for operators with different skill levels. The device supports automated operation, reduces the complexity and error of manual operation, and improves work efficiency.

[0014] 3. By improving cutting speed and precision, this invention significantly enhances the processing efficiency of live wires. Traditional wire cutting methods often require long downtime or manual intervention, while the device of this invention can perform cutting operations continuously and efficiently, reducing downtime during production and significantly improving production efficiency. In addition, the high stability and durability of the device reduce equipment failure rate and maintenance costs. Attached Figure Description

[0032] The clamp drive screw 1-14 is a trapezoidal screw, and the clamp drive screw 1-14 self-locks when the clamp drive motor 1-10 stops.
