Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting devices, and more particularly to a longitudinal cutting device for wire and cable insulation. Background Technology
[0002] Wires and cables are wire products used to transmit electrical energy, electrical signals, and realize electromagnetic energy conversion. They are widely used in many fields such as power, communication, and construction. The conductor is the part of the wire or cable that conducts current, while the insulation layer wraps around the conductor to isolate it from the external environment and prevent current leakage and short circuits. The longitudinal cutting device is a device used to cut the insulation layer of the wire or cable along the axial direction. For example, a mechanical blade cutting device usually consists of a blade, a feeding mechanism, and a positioning mechanism. The blade is generally made of high-strength, sharp alloy steel. The feeding mechanism controls the movement of the blade along the cable axis to achieve longitudinal cutting of the insulation layer. The positioning mechanism is used to ensure the accurate position of the cable during the cutting process and prevent cutting deviation.
[0003] Existing cutting devices mostly use unidirectional limiting for cables. Since the diameter of cables varies, if the limiting structure of the device is not easy to adjust, the cable may be inaccurately positioned during the cutting process, resulting in shaking or displacement. This causes the cutting position to deviate from the preset path, resulting in a non-straight cut and affecting the accuracy of subsequent processing or installation.
[0004] Therefore, since most existing cutting devices use unidirectional limiting for cables, which may lead to inaccurate positioning of the cable during the cutting process, causing the cutting position to deviate from the preset path and affecting subsequent processing or installation, a longitudinal cutting device for wire and cable insulation can be designed, which adopts an adjustable limiting structure to improve the accuracy of cable cutting. Utility Model Content
[0005] To overcome the problem that existing cutting devices mostly use unidirectional limiting for cables, which may lead to inaccurate positioning of the cable during the cutting process, causing the cutting position to deviate from the preset path and affecting subsequent processing or installation.
[0006] The technical solution of this utility model is as follows: a longitudinal cutting device for wire and cable insulation, including an operating table, a U-shaped frame, a limiting ring, and a rectangular slide rail; a U-shaped frame is fixedly installed at the middle of the upper end of the operating table, and three sets of limiting rings are arranged laterally on one side of the U-shaped frame for adjusting and fixing according to the cable diameter. A rectangular slide rail for pulling the cable is arranged on the side of the U-shaped frame away from the limiting rings, corresponding to the limiting rings. Four sets of arc-shaped telescopic sleeves are arranged around the middle of the inner side of the limiting rings. An arc-shaped telescopic plate is sleeved and connected between every two sets of arc-shaped telescopic sleeves. Multiple sets of circular telescopic columns are longitudinally installed at intervals on the middle of the outer side of the arc-shaped telescopic sleeves. Circular telescopic sleeves are sleeved on the outside of the circular telescopic columns, and the circular telescopic sleeves pass through the limiting rings and are fixedly connected to them.
[0007] Furthermore, an operation panel is installed on one side of the U-shaped frame, and three sets of rectangular telescopic sleeves are installed horizontally in the middle of the U-shaped frame, with the first cylinder installed at the upper end of the rectangular telescopic sleeves.
[0008] Furthermore, a rectangular telescopic column is fitted inside the rectangular telescopic sleeve, and a cutter is installed at the lower end of the rectangular telescopic column.
[0009] Furthermore, a base that is fixedly connected to the operating table is installed at the lower end of the limit ring.
[0010] Furthermore, an arc-shaped rubber pad is installed on the inner side of the arc-shaped telescopic sleeve, and a second cylinder is installed on the end of the circular telescopic sleeve away from the circular telescopic column.
[0011] Furthermore, a rectangular groove is provided above the rectangular slide rail, and a threaded rod is longitudinally inserted through the inner side of the rectangular groove of the rectangular slide rail, with a rotating motor installed at one end of the threaded rod.
[0012] Furthermore, a rectangular threaded sleeve is fitted around the outside of the threaded rod. Two sets of grippers are rotatably mounted on the side end of the rectangular threaded sleeve. A drive motor is installed on the side end of the rectangular threaded sleeve, and the output shaft of the drive motor is fixed to the rotating shaft of the grippers.
[0013] The beneficial effects of this utility model are as follows: the specially designed limiting ring and the gripper on the rectangular slide rail work together to provide multiple stable fixing methods for the cable. The cable passes through the limiting ring and is clamped by the gripper. Then, the arc-shaped telescopic sleeve and arc-shaped telescopic plate inside the limiting ring are used to finely adjust the limiting according to the cable diameter, ensuring that the cable remains stable before, during and after cutting, and preventing slippage or displacement, thus creating conditions for precise cutting.
[0014] The adjustable limiting structure is the core innovation of the device. This structure can be precisely adjusted according to the different sizes and specifications of wires and cables. It can not only firmly fix the cable position, but also accurately control the cutting force. As a result, the cutting device can be used for various cables, whether it is a thin-diameter electronic cable or a thick-diameter power cable. With just a simple adjustment of the spacing of the fixing structure, the cutter can accurately cut along the longitudinal center line of the cable, ensuring that the cut is flat and straight, greatly improving the cutting accuracy, meeting the needs of high-precision processing, effectively improving the quality of cable cutting, reducing the scrap rate, saving costs for cable processing companies, and enhancing their market competitiveness.
[0015] In addition, during operation, all components of the cutting device work together. The gripper precisely pulls the cable to the cutting area, and the cutter, in conjunction with the traction action, performs the cutting. The entire process is efficient and smooth. Its stable fixing and cutting methods reduce rework and equipment wear caused by cutting deviations, improve production efficiency, and provide the wire and cable processing industry with an efficient, accurate, and highly adaptable cutting solution, thus promoting the industry's technological development.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Example 1
[0024] like Figures 1-5 As shown, the longitudinal cutting device for wire and cable insulation includes an operating platform 1, a U-shaped frame 2, a limiting ring 3, and a rectangular slide rail 4. The U-shaped frame 2 is fixedly installed at the upper center of the operating platform 1. Three sets of limiting rings 3 are arranged laterally on one side of the U-shaped frame 2 for adjusting and fixing according to the cable diameter. On the side of the U-shaped frame 2 away from the limiting rings 3, a rectangular slide rail 4 for pulling the cable is provided corresponding to the limiting rings 3. Four sets of arc-shaped telescopic sleeves 302 are arranged around the inner center of the limiting rings 3. An arc-shaped telescopic plate 303 is sleeved and connected between every two sets of arc-shaped telescopic sleeves 302. Multiple sets of circular telescopic columns 305 are longitudinally spaced on the outer center of the arc-shaped telescopic sleeves 302. Circular telescopic sleeves 306 are sleeved on the outside of the circular telescopic columns 305. The circular telescopic sleeves 306 pass through the limiting rings 3 and are fixedly connected to them.
[0025] An operation panel 201 is installed on one side of the U-shaped frame 2. Three sets of rectangular telescopic sleeves 202 are installed horizontally in the middle of the U-shaped frame 2. A first cylinder 205 is installed on the upper end of the rectangular telescopic sleeve 202. Driven by the first cylinder 205, the rectangular telescopic column 203 drives the cutter 204 to move downward along the rectangular telescopic sleeve 202.
[0026] A rectangular telescopic sleeve 202 is fitted inside a rectangular telescopic column 203. A cutter 204 is installed at the lower end of the rectangular telescopic column 203. The cutter 204 continuously approaches the cable insulation layer and cuts it.
[0027] The lower end of the limit ring 3 is fitted with a base 301 that is fixedly connected to the operating table 1.
[0028] An arc-shaped rubber pad 304 is installed on the inner side of the arc-shaped telescopic sleeve 302. A second cylinder 307 is installed on the end of the circular telescopic sleeve 306 away from the circular telescopic column 305. Driven by the second cylinder 307, the circular telescopic column 305 drives the arc-shaped telescopic sleeve 302 to move along the circular telescopic sleeve 306.
[0029] A rectangular slide rail 4 has a rectangular slide groove 401 on its upper part. A threaded rod 402 is longitudinally inserted through the rectangular slide groove 401 on the rectangular slide rail 4. A rotating motor 403 is installed at one end of the threaded rod 402. Driven by the rotating motor 403, the threaded rod 402 rotates, causing the rectangular threaded sleeve 404 to drive the gripper 405 to move laterally along the rectangular slide groove 401 on the rectangular slide rail 4.
[0030] A rectangular threaded sleeve 404 is fitted on the outside of the threaded rod 402. Two sets of grippers 405 are rotatably mounted on the side end of the rectangular threaded sleeve 404. A drive motor is installed on the side end of the rectangular threaded sleeve 404. The output shaft of the drive motor is fixed to the rotating shaft of the gripper 405. The gripper 405 pulls the cable and works with the cutter 204 to cut the cable longitudinally.
[0031] First, the cable is passed through the limiting ring 3. Then, driven by the drive motor, the gripper 405 clamps one end of the cable. Then, according to the cable diameter, driven by the second cylinder 307, the circular telescopic column 305 drives the arc-shaped telescopic sleeve 302 to move along the circular telescopic sleeve 306. At the same time, the arc-shaped telescopic plate 303 retracts and adjusts along the arc-shaped telescopic sleeve 302 until the arc-shaped rubber pad 304 comes close to the cable and limits it. After confirming that there is no problem, controlled by the operation panel 201, driven by the first cylinder 205, the rectangular telescopic column 203 drives the cutter 204 to move downward along the rectangular telescopic sleeve 202, so that the cutter 204 continuously approaches the cable insulation layer. Then, driven by the rotation motor 403, the threaded rod 402 rotates, so that the rectangular threaded sleeve 404 drives the gripper 405 to move laterally along the rectangular slide groove 401 on the rectangular slide rail 4, to pull the cable and, together with the cutter 204, to cut the cable longitudinally.
