Description
Technical Field
[0001] This application relates to the technical field of wire stripping equipment for cable production, specifically a high-efficiency wire stripping device for wire and cable production. Background Technology
[0002] As core basic materials in fields such as power transmission and information communication, wires and cables occupy an indispensable position in modern industry and daily life. With the accelerated advancement of global industrialization and the rapid development of intelligent and digital technologies, the demand for wires and cables in various industries is showing a continuous growth trend. During the production process of wires and cables, it is necessary to crimp terminals and tin the ends. When cutting the cables, it is necessary to strip the ends of the cut wires and cables, which requires a wire stripping device.
[0003] Existing wire stripping devices typically use flat-bladed wire strippers to strip the ends of cables, which cannot completely cut the wire insulation around the cable ends. The uncut insulation needs to be pulled off, resulting in uneven stripping cuts that affect subsequent work such as crimping terminals and soldering the cable ends. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this application provides a high-efficiency wire stripping device for wire and cable production. This device can completely cut and separate the wire insulation around the cable end without requiring dragging to break the insulation, resulting in a smoother stripping cut and improved quality. It solves the problem that existing stripping devices typically use a flat-bladed stripper to strip the cable end, which cannot completely cut the insulation around the cable end and requires dragging to break any uncut insulation, leading to an uneven stripping cut that affects subsequent crimping and soldering of the cable end.
[0005] To achieve the goal of completely cutting and separating the wire sheath around the cable end without using a dragging method to break the wire sheath, resulting in a smoother stripping cut at the cable end and improving the quality of cable stripping, this application provides the following technical solution: A high-efficiency wire stripping device for wire and cable production, comprising a frame, with two connecting plates arranged vertically on the inner side of the frame. The two connecting plates are respectively mounted on the top and bottom of the inner wall of the frame via two hydraulic rods. Each of the two connecting plates has a cutting blade on its opposite side, and two stripping blades are mounted at both ends of each side of the two connecting plates. The two corresponding stripping blades are located on both sides of the corresponding cutting blade. An arc-shaped groove is formed at the end of the stripping blade away from the corresponding connecting plate. The dimensions of the arc-shaped grooves of the two corresponding stripping blades are adapted to the dimensions of the cable when they are joined. Two traction mechanisms are mounted on one side of the inner wall in the middle of the frame via a fixing frame, and the two traction mechanisms are located on the outer sides of both ends of the connecting plates.
[0006] The above solution uses two corresponding wire strippers connected at the top and bottom to allow the two arc-shaped grooves of the two strippers to work together to completely cut and separate the wire sheath around the cable end, while avoiding damage to the cable core. This achieves complete cutting and separation of the wire sheath around the cable end without the need for dragging, which would break the wire sheath at the cable end. The resulting stripping cut at the cable end is relatively smooth, improving the quality of the wire stripping work.
[0007] Furthermore, the two tangent blades are staggered left and right, with the cutting edges of the two tangent blades located on opposite sides of each other, and the opposite sides of the two tangent blades sliding relative to each other.
[0008] The above scheme avoids collisions between the two cutting blades on their travel path by setting the two cutting blades to be staggered to the left and right. This allows the two cutting blades to overlap when they approach each other to cut the cable, enabling them to work together to completely cut the cable. At the same time, when the connecting plate moves continuously, it drives the two corresponding stripping blades to approach each other to strip the cable, avoiding interference from the two cutting blades. This allows the connecting plate to continue moving after the cutting blades have cut the cable, enabling the stripping blades to strip the cut ends of the cable.
[0009] Furthermore, each of the two connecting plates has two telescopic rods at both ends on opposite sides, and one end of the telescopic rod has a gripper, which is located outside the corresponding two wire strippers.
[0010] The above solution allows the cable to be clamped and fixed before stripping by using the clamps, so that the end of the cable can be accurately embedded into the arc groove. This allows the stripper to work with the arc groove to accurately strip the end of the cable.
[0011] Furthermore, multiple gripping balls are rotatably arranged on the inner wall of the inner side of the gripper.
[0012] The above scheme, by setting the clamping ball, allows the cable to move smoothly along the axial direction of the clamps after being clamped and positioned by the upper and lower clamps, so that the traction mechanism can smoothly drive the cable to move and adjust the stripping position of the cable end.
[0013] Furthermore, the telescopic rod is equipped with a spring inside, with one end of the spring located at one end of the inner wall of the telescopic outer tube and the other end of the spring located at one end of the telescopic inner rod.
[0014] The above solution utilizes a spring to apply a thrust to the telescopic rod, allowing the upper and lower grippers to work together to clamp the cable. The movement of the connecting plate then causes the telescopic rod to retract. Simultaneously, the spring's thrust ensures the telescopic rod and grippers stably clamp the cable, preventing the connecting plate's movement from being affected by the telescopic rod and grippers. This allows the grippers to pre-position the cable before the wire cutter and stripper contact it, enabling the wire cutter and stripper to precisely and stably process the cable.
[0015] Furthermore, a positioning frame is provided on one side of the inner wall of the frame via a fixing bracket. The inner wall of the middle part of the positioning frame is fitted onto the outer surface of the middle part of the positioning rod, and one end of the positioning rod is located on the side of the positioning plate away from the gripper.
[0016] The above solution allows the positioning plate's angle to be fixed by sliding the outer surface of the middle part of the positioning rod within the inner wall of the middle part of the positioning frame, thereby improving the stability of the positioning plate during movement.
[0017] Furthermore, one side of the outer surface of the middle part of the two corresponding telescopic rods is hinged to a swing rod by a hinge frame. The two corresponding swing rods are arranged symmetrically, and one end of the two corresponding swing rods is hinged to the two ends of the same positioning plate by two hinge frames.
[0018] The above scheme uses two symmetrically arranged swing rods in conjunction with a positioning plate to control the two telescopic rods to extend and retract at the same distance, so that the two grippers can always move symmetrically in the center, thereby enabling the two grippers to cooperate with each other to stably clamp the cable in the center.
[0019] Furthermore, the cutting blade is made of high-carbon steel.
[0020] The above solution, by using high-carbon steel for the tangent blade, ensures that the tangent blade maintains excellent hardness during long-term, high-frequency use, making the cutting edge less prone to wear and deformation, and thus improving the service life of the tangent blade.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This high-efficiency wire stripping device for wire and cable production uses two corresponding stripping blades that are connected to each other. The two arc-shaped grooves of the two stripping blades work together to completely cut and separate the wire sheath around the cable end, avoiding damage to the cable core. It can completely cut and separate the wire sheath around the cable end without using a dragging method to break the wire sheath at the cable end, resulting in a smoother stripping cut at the cable end and improving the quality of wire stripping work.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] Please see Figure 1 , Figure 2 and Figure 5This embodiment of a high-efficiency wire stripping device for wire and cable production includes a frame 1. Two connecting plates 2 are provided on the inner side of the frame 1, which are arranged vertically. The two connecting plates 2 are respectively set at the top and bottom of the inner wall of the frame 1 by two hydraulic rods 3. A wire cutting knife 4 is provided on the opposite side of the two connecting plates 2. Two wire stripping knives 5 are provided at both ends of one side of the two connecting plates 2. The two corresponding wire stripping knives 5 are located on both sides of the corresponding wire cutting knife 4. An arc-shaped groove 6 is opened at the end of the wire stripping knife 5 away from the corresponding connecting plate 2. The size of the arc-shaped grooves 6 of the two corresponding wire stripping knives 5 when they are connected is adapted to the size of the cable. Two traction mechanisms 15 are provided on one side of the inner wall in the middle of the frame 1 by a fixing frame. The two traction mechanisms 15 are located on the outer side of both ends of the connecting plates 2.
[0032] Please see Figure 1 and Figure 2 The two cutting blades 4 are staggered left and right, with their cutting edges positioned on opposite sides. These opposite sides slide against each other. This staggered arrangement prevents the two cutting blades 4 from interfering with each other on their path, allowing their cutting edges to overlap when cutting the cable. This enables the two cutting blades 4 to work together to completely cut the cable. Simultaneously, the connecting plate 2 continuously moves, causing the corresponding stripping blades 5 to move closer together to strip the cable. This avoids interference from the two cutting blades 4, allowing the connecting plate 2 to continue moving after the cutting blades 4 have cut the cable, enabling the stripping blades 5 to continue stripping the cut ends of the cable.
[0033] Please see Figure 1 , Figure 2 and Figure 4 Two telescopic rods 7 are provided at both ends of the opposite side of the two connecting plates 2. One end of the telescopic rod 7 is provided with a clamp 8. The clamp 8 is located on the outside of the corresponding two wire strippers 5. The clamp 8 can clamp and fix the cable in advance before stripping, so that the end of the cable can be accurately embedded into the arc groove 6. Thus, the wire stripper 5 can accurately strip the end of the cable in conjunction with the arc groove 6.
[0034] Please see Figure 1 and Figure 4 Multiple clamping balls 10 are rotatably arranged on the inner wall of the inner side of the clamping claw 8. The clamping balls 10 enable the cable to move smoothly along the axial direction of the clamping claw 8 after it is clamped and positioned by the upper and lower clamping claws 8, so that the traction mechanism 15 can smoothly drive the cable to move and adjust the stripping position of the cable end.
[0035] Please see Figure 4The telescopic rod 7 is equipped with a spring 9 inside. One end of the spring 9 is located on one end of the inner wall of the telescopic outer tube of the telescopic rod 7, and the other end of the spring 9 is located on one end of the telescopic inner rod of the telescopic rod 7. The spring 9 can apply a pushing force to the telescopic rod 7, so that the upper and lower clamps 8 cooperate to clamp the cable. After the connecting plate 2 moves, the telescopic rod 7 can retract. At the same time, the pushing force of the spring 9 can make the telescopic rod 7 and the clamps 8 stably clamp the cable, so that the movement of the connecting plate 2 can be avoided by the telescopic rod 7 and the clamps 8. The clamps 8 can clamp and position the cable in advance before the wire cutter 4 and the wire stripper 5 come into contact with the cable, so that the wire cutter 4 and the wire stripper 5 can process the cable accurately and stably.
[0036] Please see Figure 1 , Figure 3 and Figure 4 A positioning frame 14 is provided on one side of the inner wall of the frame 1 via a fixed frame. The inner wall of the middle part of the positioning frame 14 is fitted onto the outer surface of the middle part of the positioning rod 13. One end of the positioning rod 13 is located on the side of the positioning plate 12 away from the gripper 8. The angle of the positioning plate 12 when it moves can be fixed by sliding the outer surface of the middle part of the positioning rod 13 within the inner wall of the middle part of the positioning frame 14, thereby improving the stability of the positioning plate 12 when it moves.
[0037] Please see Figure 1 , Figure 3 and Figure 4 Each of the two corresponding telescopic rods 7 has a swing rod 11 hinged to one side of the outer surface of the middle part of the telescopic inner rod through a hinge frame. The two corresponding swing rods 11 are symmetrically arranged vertically. One end of the two corresponding swing rods 11 is hinged to both ends of the same positioning plate 12 through two hinge frames. By using the two symmetrically arranged swing rods 11 in conjunction with the positioning plate 12, the two telescopic rods 7 can be controlled to extend and retract at the same distance, so that the two grippers 8 can always move symmetrically in the center, thereby enabling the two grippers 8 to cooperate with each other to stably clamp the cable in the center.
[0038] Please see Figure 1 , Figure 2 and Figure 3 The cutting blade 4 is made of high-carbon steel. The use of high-carbon steel in the cutting blade 4 ensures that it maintains excellent hardness during long-term, high-frequency use, making the cutting edge of the cutting blade 4 less prone to wear and deformation, thus improving the service life of the cutting blade 4.
[0039] This embodiment of a high-efficiency wire stripping device for wire and cable production uses two corresponding upper and lower stripping blades 5 to connect, so that the two arc-shaped grooves 6 of the two stripping blades 5 cooperate to completely cut and separate the wire sheath around the cable end, and avoid damage to the cable core. It can completely cut and separate the wire sheath around the cable end without using the dragging method to break the wire sheath at the cable end, and the stripping cut at the cable end is relatively flat, which improves the work quality of stripping the wire end of the cable.
[0040] The working principle of the above embodiment is as follows: Two traction mechanisms 15 work together to pull the cable to be cut between the upper and lower cutting blades 4. Two hydraulic rods 3 operate, causing the two connecting plates 2 to move relative to each other, bringing them closer together. The connecting plates 2 then move the two upper and lower telescopic rods 7 in opposite directions, causing the two corresponding grippers 8 to move closer together, thus clamping and positioning the cable. The continuous movement of the connecting plates 2 causes the upper and lower cutting blades 4 to move closer together, allowing them to cut the cable. Simultaneously, the continuous movement of the two connecting plates 2 causes the telescopic rods 7 to move closer together. Rod 7 retracts, compressing spring 9. Two traction mechanisms 15 pull the cut cable, drawing the end of the cable to be stripped between the two corresponding stripping blades 5. The two connecting plates 2 continuously move closer to each other, causing the two corresponding stripping blades 5 to move closer together and align. The two arc-shaped grooves 6 on the two corresponding stripping blades 5 work together to completely cut the insulation around the cable end, completely separating the insulation from the cable end. The traction mechanism 15 then pulls the cable, causing the cut insulation at the cable end to separate from the cable through the obstruction of the stripping blades 5, thus completing the stripping of the cable end.
