Description

Technical Field

[0001] This invention relates to the field of wire and cable processing technology, specifically to an aviation wire and cable processing device. Background Technology

[0002] Currently, the treatment of waste wires and cables involves high-temperature melting to separate the cable sheath from the metal core. This method is relatively easy for ordinary wires and cables, but for high-temperature resistant or fire-resistant wires and cables, such as aviation wires and cables, melting the sheath is relatively difficult and causes greater environmental pollution. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an aviation wire and cable processing device to solve the aforementioned technical problems.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] An aviation wire and cable processing device includes a device body with an inlet on one side and an outlet on the other side, the inlet and outlet being coaxially arranged. A first cutting tube and a second cutting tube are disposed within the device body, coaxially arranged with the inlet. The second cutting tube is fixed within the device body. One end of the first cutting tube is rotatably connected to the device body, and the other end is rotatably connected to the second cutting tube. A first driving device for driving the first cutting tube to rotate is disposed within the device body. A spiral blade is disposed inside the first cutting tube, and a cutting blade is disposed on the inner wall of the second cutting tube parallel to its axial direction.

[0006] Preferably, there are multiple cutting blades arranged circumferentially inside the second cutting tube.

[0007] Preferably, the first driving device is a motor, which is connected to the first cutting tube via a belt.

[0008] Preferably, a first partition and a second partition are fixed between the second cutting tube and the outlet, with the first partition closer to the second cutting tube than the second partition; a first through hole is provided on the first partition, and a central tube is rotatably connected to the inner wall of the outlet, with one end of the central tube not connected to the outlet passing through the second partition and located within the first through hole; the second partition is rotatably connected to the central tube; a key is provided on the central tube at a position between the second and second partitions, and a disc is fitted onto the central tube, with a keyway corresponding to the key on the disc, the length of which is... The length is less than that of the key; a pair of first magnets are fixed on one side of the second partition corresponding to the first partition, and a pair of second magnets are arranged on the disk corresponding to the positions of the first magnets. The polarities of the two first magnets are opposite at one end of the first partition; the polarities of the two second magnets are opposite at one end of the second partition; the two first magnets are symmetrically arranged with the central tube as a reference; a plurality of steel needles are arranged circumferentially on the disk, and the steel needles are located between the first through hole and the central tube. A second driving device for driving the central tube to rotate is arranged on the side of the second partition facing the outlet inside the device body.

[0009] Preferably, the second drive device is a motor, which is connected to the central tube via a belt.

[0010] The aviation wire and cable processing equipment provided by this invention allows the wire or cable to enter through an inlet. As the wire or cable advances, it encounters rotating helical blades, which cut its outer sheath into a spiral shape. The wire or cable continues to advance with the assistance of the helical blades. When it encounters a cutting blade, the helical outer sheath is cut into segments, and finally, it is discharged through a second cutting tube. This structure eliminates the need for melting and removing the wire or cable sheath, making operation simpler and causing less or no environmental pollution. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] For examples, please refer to Figure 1 and Figure 2 This embodiment provides an aviation wire and cable processing device, including a device body 1. An inlet 2 is provided on one side of the device body, and an outlet 3 is provided on the other side. The inlet and outlet are coaxially arranged. A first cutting tube 4 and a second cutting tube 5 are disposed within the device body. The first and second cutting tubes are coaxially arranged with the inlet. The second cutting tube is fixed within the device body. One end of the first cutting tube is rotatably connected to the device body, and the other end is rotatably connected to the second cutting tube. A first driving device for driving the first cutting tube to rotate is disposed within the device body. In this embodiment, the first driving device is a motor 8, which is connected to the first cutting tube via a belt 9, or alternatively, a gear connection. A spiral blade 6 is disposed inside the first cutting tube. The spiral blade can be a single blade or multiple blades combined into one; no specific limitation is made here. Cutting blades 7 are disposed on the inner wall of the second cutting tube parallel to its axis. The cutting blades can be a single blade or multiple blades circumferentially disposed within the second cutting tube; further details are omitted here.

[0017] In operation, the aforementioned aviation cable processing equipment allows the cable to enter through the left-side inlet. As the cable advances, it encounters rotating helical blades, which cut the cable sheath into a spiral shape. The cable continues forward with the assistance of the helical blades, and upon encountering the cutting blades, the spiral sheath is cut into segments, ultimately exiting through the second cutting tube. This structure eliminates the need for melting and removing the cable sheath, resulting in simpler operation and minimal or no environmental pollution.

[0018] In actual manufacturing, the contact between the spiral blade and the cutting blade and the metal core is generally not particularly tight to prevent scratching the metal core or damaging the blade. Therefore, when cutting the outer skin, sometimes there are threads left after the outer skin is cut. To address this, the applicant has also made the following design: A first partition 10 and a second partition 11 are fixed between the second cutting tube and the outlet. The first partition is closer to the second cutting tube than the second partition. A first through hole is provided on the first partition. A central tube 12 is rotatably connected to the inner wall of the outlet. The end of the central tube not connected to the outlet passes through the second partition and is located in the first through hole. The second partition is rotatably connected to the central tube. A key 12-1 is provided on the central tube at a position between the second partition and the second partition. A disc 15 is sleeved on the central tube. A keyway 15-1 is provided corresponding to the key, and the length of the keyway is less than the length of the key; a pair of first magnets 13 are fixed on one side of the second partition corresponding to the first partition, and a pair of second magnets 14 are provided on the disk corresponding to the positions of the first magnets. The polarities of the two first magnets at one end of the first partition are opposite; the polarities of the two second magnets at one end of the second partition are opposite; the two first magnets are symmetrically arranged with the central tube as a reference; a plurality of steel needles 16 are arranged circumferentially on the disk, and the steel needles are located between the first through hole and the central tube. A second driving device for driving the central tube to rotate is provided on the side of the second partition facing the outlet inside the device body. In this embodiment, the second driving device can also be a motor, which is connected to the central tube via a belt or via gears.

[0019] In use, this structure drives the disk to rotate via a second drive device, preferably a stepper motor or a servo motor. Figure 1 As shown, every time the disc rotates 180°, the first and second magnets change from a repulsive state to an attractive state, and the disc moves back and forth. When the cable moves to the right end of the second cutting tube, the disc drives the steel needle to insert into the cable sheath to the left, and rotates after inserting into the sheath to break the threaded part. Then it drives the sheath to move to the right. When the sheath encounters the edge of the central tube and the first through hole, it is blocked and falls off. This operation is repeated to prevent the sheath from being threaded and falling off.
