DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the invention, and these aspects of the present invention can be realized even without these specific details.

[0025] See also Figures 1 to 6 The present invention provides a high-voltage cable metal sheath corrugation device, and the technical solution is as follows:

[0026] The invention comprises a shell, wherein two mounting seats 1 are symmetrically arranged inside the shell, and the two mounting seats 1 are arranged opposite to each other, each mounting seat 1 is provided with a mounting plate 2, and a protective shell 3 is provided between the two mounting plates 2, and a chip removal groove 4 is provided at the bottom of the protective shell 3, and a through hole is provided on the two mounting seats 1, and the left end of the left mounting seat 1 is a feed port 5, and the right end of the right mounting seat 1 is a discharge port 6, a driving unit 7 is provided in the right mounting seat 1, and a rotating shaft 1 8 is provided on the right mounting plate 2, and a rotating shaft 2 11 is provided on the left mounting plate 2, and a connecting ring 1 9 is provided on the rotating shaft 1 8, and a connecting ring 1 9 is symmetrically provided with Two extension plates 10, a connecting ring 2 12 is provided on the rotating shaft 2 11, and two extension plates 2 13 are symmetrically provided on the connecting ring 2 12, the diameter of the connecting ring 1 9 is larger than the connecting ring 2 12, a guillotine seat 14 is provided at the center of the protective shell 3, the guillotine seat 14 is annular, and a plurality of corrugating cutter heads 15 are evenly arranged in the guillotine seat 14, the extension plates 10 and 13 on the same side are arranged in an overlapping manner up and down, and are connected to the guillotine seat 14 through a screw, an adjusting component for synchronously adjusting the feeding depth of a plurality of corrugating cutter heads 15 is provided in the guillotine seat 14, and fixing components are provided at the feed port 5 and the discharge port 6.

[0027] During the preparation of high-voltage cables, the cables are wrapped with metal sheaths, and then the metal sheaths need to be corrugated by corrugating equipment. Corrugation can form the metal sheath into regular corrugations, which can provide a certain amount of expansion and contraction space, increase the degree of freedom of bending, improve the bending performance of the cable, and reduce the bending stress and the risk of damage caused by bending. In addition, corrugation can increase the surface area of ​​the metal sheath, and the contact area with the surrounding air or other media increases accordingly, thereby improving the heat dissipation efficiency.

[0028] The existing corrugating device generally corrugates the rotating cable by fixing the corrugating cutter head 15, and corrugates the cable by rotating multiple corrugating cutter heads 15, so that multiple corrugations can be completed at one time. Compared with the rotating cable method in which only one position of the cable can be corrugated each time, the corrugating time is reduced and the production efficiency is improved; and when the corrugating cutter seat 14 is rotated, the contact position and pressure between the corrugator and the cable metal sheath are easier to control and maintain stable, which can make the corrugation depth, width and other parameters more uniform and consistent, and avoid the situation of uneven corrugation depth; when the cable is rotated, the cable may shake easily during the rotation process, resulting in uneven corrugation;

[0029] The cable is put in from the feed port 5 and then extended from the discharge port 6. The cable is fixed by two fixing components. The fixing components can fix the cable in the vertical direction. The cable is moved by an external driving force and will not be affected by the fixing components. The multiple corrugating cutter heads 15 are adjusted to a suitable feeding depth by the adjusting component, and then the driving unit 7 is started. The rotating shaft 11 is driven to rotate by the rotating shaft 1 8, and the corrugating cutter seat 14 is driven to rotate by the extension plate 10 and the extension plate 2 13. At the same time, the external driving device drives the cable to continue passing through the corrugating cutter seat 14, and the cable is corrugated. During the corrugating operation, the metal outer skin contacts the multiple corrugating cutter heads 15, and the generated debris falls into the protective shell 3. The protective shell 3 is cylindrical, and a chip discharge groove 4 is opened at the lower end. The debris is discharged from the chip discharge groove 4 to the outside of the protective shell 3.

[0030] The adjustment assembly includes an operating hole 16 provided on the outer circumferential wall of the guillotine seat 14, a cavity is provided in the guillotine seat 14, and a gear ring 17 is provided in the cavity, the inner ring of the gear ring 17 is provided with inner ring teeth, and the outer ring is provided with outer ring teeth, and a worm 18 meshing with the outer ring teeth is provided outside the gear ring 17, three tooth columns 19 are evenly provided in the gear ring 17, and each tooth column 19 is meshed with the inner ring teeth of the gear ring 17, three slide grooves are provided in the inner ring of the guillotine seat 14, and a rack 20 is provided in each slide groove, and each of the racks 20 is connected to a corrugating cutter head 15 at one end close to the center of the gear ring 17, and each rack 20 is meshed with the corresponding tooth column 19.

[0031] The tool is inserted into the operating hole 16 and engaged with the operating groove at the top of the worm 18. The worm 18 drives the gear ring 17 to rotate, thereby driving the three gear columns 19 to rotate synchronously. The gear column 19 is meshed with the rack 20, thereby driving the three racks 20 to be adjusted synchronously in the corresponding slide grooves. Cables of different diameters can be adjusted conveniently, which greatly improves the adaptability of the embossing cutter seat 14 and is easy to operate. The three corrugating cutter heads 15 can be adjusted by one operating worm 18. Compared with the existing corrugating cutter heads 15 that need to be adjusted one by one, the convenience is improved.

[0032] The fixing assembly includes a three-jaw chuck 21 respectively arranged at the feed port 5 and the discharge port 6, each of the three-jaw chuck 21 is provided with three movable jaws 22, and each movable jaw 22 is provided with a limiting plate 23 at one end close to the center of the three-jaw chuck 21, each of the limiting plates 23 is an arc plate, and the three arc plates cooperate with each other, each of the arc plates is provided with a plurality of balls 24, and each ball 24 can rotate on its own.

[0033] The three curved plates cooperate with each other to better fit the cable surface. When the three curved plates fit the outer surface of the cable, they can apply uniform pressure to the cable at three different positions to form a stable three-point support structure to stabilize the cable, effectively preventing the cable from shaking or shifting during processing or use, ensuring that the cable is in the correct position and ensuring the accuracy and stability during the corrugation process;

[0034] A plurality of self-rotating balls 24 are provided on each curved plate. While the three-jaw chuck 21 can provide radial stability for the cable, the plurality of balls 24 reduce the axial friction between the cable and the curved plate. The presence of the balls 24 converts the sliding friction between the curved plate and the outer surface of the cable into rolling friction, so that the cable can move continuously and stably, thus ensuring the subsequent corrugation effect of the cable.

[0035] Each of the mounting plates 2 is provided with an annular groove 25, and an arc-shaped protective cover 26 is provided in the two annular grooves 25. A handle 27 is provided on the outer circumference of the protective cover 26. An interception plate 28 is provided at the lower end between the two mounting plates 2. The mounting plates 2 are provided with an anti-mistaken touch component that cooperates with the protective cover 26; the annular groove 25 on the protective shell 3 can be closely matched with the protective cover 26 to form an effective sealing structure, which can prevent debris, dust, etc. from entering the working area of ​​the milling cutter seat 14, avoid foreign matter from interfering with the normal operation of the milling cutter seat 14, and ensure the normal operation of the milling cutter seat 14. The embossing work can be smoothly carried out; at the same time, the debris generated by the embossing is also intercepted by the protective cover 26 in the protective shell 3 to prevent the debris from flying around randomly and preventing it from being difficult to handle after the embossing; during the embossing operation, the embossing cutter runs at a high speed, which is very dangerous; the anti-mistouch component ensures that the embossing operation can only be started after the protective cover 26 is closed in place to form an effective protective barrier, thereby preventing the operator or other personnel from accidentally touching the embossing cutter when the protective cover 26 is not closed, preventing serious cuts or injuries to the hands, body and other parts, and ensuring the physical safety of the personnel to the greatest extent.

[0036] The anti-mistouch component includes a groove 29 opened at the lower end of the right mounting plate 2, and a contact member 30 is arranged in the groove 29. The contact member 30 can be a contact switch. The contact member 30 is electrically connected to the drive unit 7. A connecting plate 31 is provided on the protective cover 26. An elastic member 32 is provided on the connecting plate 31. The elastic member 32 can be a telescopic rod. A spring is provided inside the telescopic rod, and the elastic member 32 cooperates with the contact member 30.

[0037] After completing the preparatory actions before the cable corrugation operation, the protective cover 26 is slid downward in the annular groove 25 through the handle 27 until it contacts the interception plate 28, that is, the protective cover 26 is closed. During the process, the elastic member 32 moves with the protective cover 26 until the elastic member 32 enters the groove 29 and contacts the contact member 30, and the electrical signal is transmitted to the drive unit 7 through the wire, and then the drive unit 7 can be turned on to avoid accidental touch and cause injury to personnel.

[0038] The protective shell 3 is provided with an inclined platform 33 at the lower end, and the inclined platform 33 is located directly below the chip groove 4; the inclined platform 33 has a downward guiding function, and the debris falls from the chip groove 4 onto the inclined platform 33, and the debris is then moved to the outside of the protective shell 3 through the inclined platform 33, which is convenient for the staff to clean and collect the debris, thereby improving convenience.

[0039] Workflow: the staff puts the high-voltage cable to be corrugated into the feed port 5, and then extends it out from the discharge port 6, and then radially fixes the cable with the three movable claws 22 on each three-claw chuck 21 at a time, and penetrates into the operating hole 16 through the tool, and combines with the operating groove at the top of the worm 18, and drives the gear ring 17 to rotate through the worm 18, and drives the three gear columns 19 to rotate synchronously, and the gear column 19 is engaged with the rack 20, so that the three racks 20 can be driven to adjust synchronously in the corresponding slide groove, and the three corrugating cutter heads 15 are adjusted to the appropriate feed depth and then stopped. At this time, the preliminary preparation for the cable corrugation operation is completed, and then the cable is connected to the external drive device, and the protective cover 26 is closed by the handle 27. During the process, the elastic member 32 enters the groove 29 and contacts the contact member 30, giving the drive unit 7 an electrical signal, and then starting the drive unit 7, and the cutter seat 14 is driven to rotate through the rotating shaft 1 8, the rotating shaft 1 8 and the extension plate 10, and the extension plate 2 13 to perform corrugation operations on the cable.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
