Description

Technical Field

[0001] The present invention relates to the technical field of cable outer sheath shaping, and in particular to a torsion-resistant cable and shaping equipment for charging and discharging of new energy vehicles. Background Art

[0002] In the prior art, the outer sheath layer of the cable is generally formed by melt extrusion, and the outer sheath layer is extruded onto the outer layer of the cable and then passed through a cooling water tank for cooling and shaping. However, due to the effect of gravity, the outer sheath layer is prone to small-scale migration during the cooling and shaping process, resulting in uneven thickness of the outer sheath layer and the inner layer, posing a safety hazard.

[0003] Therefore, as CN202010735557.5 discloses a cooling and shaping device for manufacturing insulation sheaths of communication cables, the high speed and high pressure at the left end can be used to press the surface of the insulation sheath through the shaping wheel and rotate it quickly before the insulation sheath is completely shaped, so as to repair the marks or deformation on the surface generated in the previous cooling process. At the same time, combined with the air cooling of the annular air cavity installed on the left side of the shaping outer cylinder, it can be further cooled and shaped in time during the repair process;

[0004] However, the existing shaping component that rotates circumferentially around the cable will move relative to the cable. On the one hand, it will generate a force in the opposite direction of the cable movement. On the other hand, it will also generate a force in the tangential direction of the cable and the shaping component that is opposite to the rotation direction of the shaping component. When the force acts on the cable surface, it will further cause the cable surface to deform. Therefore, it is necessary to avoid generating forces in the above two directions and only provide a force perpendicular to the axial direction of the cable so that the outer sheath can be evenly fitted on the outer surface of the cable.

DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] like Fig.13 As shown, a torsion-resistant cable for charging and discharging of new energy vehicles includes a cable core 64 and a mica tape sheath 63, a braided shielding layer 62, an inner sheath 61 and an outer sheath 60 which are sequentially wrapped around the outside of the cable core 64. An anti-torsion layer 59 is arranged between the inner sheath 61 and the outer sheath 60. The anti-torsion layer 59 includes a positioning ring, a filling sleeve and an anti-torsion spring. The positioning rings are evenly arranged along the axial direction of the inner sheath 61, and the filling sleeve and the anti-torsion spring are respectively located between the positioning rings, and the filling sleeve and the anti-torsion spring are arranged at intervals.

[0038] When the outer sheath 60 is extruded and coated on the anti-torsion layer 59 by extrusion, compared with the flat extrusion surface, the anti-torsion cable involved in the present application is provided with multiple positioning rings, and anti-torsion springs and filling sleeves are fixed between the positioning rings. During extrusion, on the one hand, it cannot be guaranteed that a single extrusion can make the outer sheath 60 tightly combined with the anti-torsion spring, the positioning ring and the filling sleeve, and the anti-torsion spring is easy to deform during the extrusion process. After extrusion, the anti-torsion spring is reset or gravity causes the outer sheath 60 layer to migrate. After extrusion, the outer sheath 60 is easy to migrate under the action of gravity when it is not completely cooled and shaped, and the degree of migration is different at different positions, which eventually leads to uneven thickness of the outer sheath 60 of the cable 2 in the length direction. Therefore, when the cable 2 is pulled into the cooling water trough 3 after extrusion, a shaping device needs to be set in the cooling water trough 3 to shape the outer sheath 60 of the cable 2.

[0039] Therefore, the present application proposes an anti-torsion cable shaping device, which shapes the outer sheath 60 during the cooling process by setting a shaping device in the cooling water trough 3 so that the thickness of the outer sheath 60 is uniform everywhere, so as to avoid the uneven thickness problem caused by the migration of the outer sheath 60 during the cooling process under the influence of gravity, and the problem of tight combination of the outer sheath 60 with the anti-torsion spring, positioning ring, and filling sleeve.

[0040] Furthermore, an anti-torsion cable shaping device includes a frame 1, a cooling water trough 3 is arranged on the frame 1, a plurality of shaping devices are arranged in the cooling water trough 3, and the cable 2 passes horizontally through the shaping devices in the cooling water trough 3.

[0042] Furthermore, the cooling water trough 3 is composed of return water troughs at both ends and a cooling trough in the middle. The shaping equipment is located in the cooling trough. The return water trough returns the water overflowing from the cooling trough to the water storage tank 11 through the return water pipe 14. The water storage tank 11 is pumped back into the cooling trough through a water pump (arranged inside the water storage tank, not shown in the accompanying drawings) to form circulating cooling water.

[0043] Specifically, Figure 2 , Fig.11 As shown, a water tank 11 is also provided on one side of the frame 1, and a water inlet 13, a water level gauge 12 and a drain outlet are provided on the water tank 11; the water in the cooling trough continuously flows into the left return water trough from the cable outlet of the left water baffle plate, and flows into the right return water trough from the cable outlet on the right water baffle plate, and the water in the left return water trough and the right return water trough flows into the water tank 11 through the return pipe 14 and the action of gravity. A water pump is provided in the water tank 11, and the water pump pumps the water in the water tank 11 to the water supply pipe 16 at the upper part of the cooling water trough 3 through a pipeline. The water supply pipe 16 is connected to a water distribution pipe 6 arranged along the length direction of the cooling trough, and a plurality of dripping heads 17 are installed on the water distribution pipe 6. By adjusting the position of the dripping head 17 to be directly above the cable 2, water can be continuously supplied to the cooling trough and the cable 2 can be continuously cooled by water. The dripping head 17 is composed of an angle-adjustable bellows and a water outlet head at the end.

[0044] Furthermore, an air cooling component is also provided in the return water tank, and the air cooling component is composed of a spiral coil 4 with one end closed and the other end open to air. The cable passes through the central axis of the spiral coil 4, and the spiral coil 4 has a plurality of air outlet holes 47 on the side facing the cable 2.

[0045] Specifically, Figure 1-Figure 2 , Fig.12 As shown, the cable 2 passes horizontally into the cooling trough above the left return water trough, and then passes horizontally out after passing above the right return water trough, wherein air cooling components are also arranged in the left return water trough and the right return water trough, and the air cooling components have the same structure and are both spiral coils 4, and the front end of the spiral coil 4 is provided with an air inlet end 52 connected to the air outlet of the blower equipment, and the end is closed, and the coil is provided with a plurality of air outlet holes 47 on the side facing the axis, and the air cooling component is fixed to the cooling water trough 3 by a clamping part.

[0046] Specifically, the clamping member includes a front clamping plate 46 and a rear clamping plate 49. The front side of the front clamping plate 46 is rotatably connected to a front screw 50 so that the front screw 50 can rotate freely without being separated from the front clamping plate 46. The front screw 50 is connected to the front side plate by a thread. The rear side of the rear clamping plate 49 is rotatably connected to a rear screw 48 so that the rear screw 48 can rotate freely without being separated from the rear clamping plate 49. The rear screw 48 is connected to the rear side plate by a thread. The front clamping plate 46 is moved closer to or away from the spiral by rotating the front screw 50. The coil 4 is clamped by rotating the rear screw 48 to make the rear clamping plate 49 approach or move away from the spiral coil 4. When the front clamping plate 46 and the rear clamping plate 49 are close to the spiral coil 4 and in close contact with the side wall of the spiral coil 4, the spiral coil 4 is clamped. When the front clamping plate 46 and the rear clamping plate 49 are away from the spiral coil 4, the spiral coil 4 can be released. The clamping of the air-cooled component can also be fixed by any other detachable structure. The above-mentioned clamping mechanism is only a preferred structure in the present application.

[0047] Furthermore, a hydrophobic brush is provided in the return water trough at the end of the cooling water trough 3, and the hydrophobic brush is arranged in contact with the cable surface so that water droplets on the cable surface converge and drip. Preferably, a water guide bucket 51 is also provided in the return water trough at the end of the cooling water trough 3, and the water guide bucket 51 is fixed to the front end of the spiral coil 4 in the return water trough. The water guide bucket 51 is composed of a large circular hole, a small circular hole and a conical wall, and a brush is provided in the small circular hole. It can be foreseen that the above is only a preferred structure in this embodiment, and the hydrophobic brush can also be provided in other shapes, such as a circular ring shape, and a brush is provided on the inner side of the circular ring. In addition to being installed at the front end of the spiral coil 4, the fixed position can also be installed on the side wall of the return water trough or the lifting platform 7, as long as it is located before the terminal air cooling component to drain the moisture on the cable surface.

[0048] Specifically, Fig.12 As shown, a conical water guide scoop 51 is also provided at the front end of the spiral coil 4 of the right water return trough, and the water guide scoop 51 is composed of a large circular hole, a small circular hole and a conical wall, wherein the cable 2 passes through the large circular hole and the small circular hole in sequence, wherein a brush is provided in the small circular hole, and when the cable 2 passes through, the brush sweeps the circumferential surface of the cable 2 to gather the water on the circumferential surface of the cable 2 and then guides it to the water guide scoop 51, and the water guide scoop 51 guides the gathered water flow into the right water return trough, so as to cooperate with the air cooling component to recover and clean the water droplets on the surface of the cable 2.

[0049] Furthermore, the cooling trough is provided with a plurality of shaping devices which move back and forth along the length direction of the cooling trough. When the shaping devices move with the cable 2, there is no relative displacement between the shaping devices and the cable 2. When the shaping devices and the cable 2 move in opposite directions, the shaping devices are reset and after reset, they are fitted with the next section of the unshaped cable 2.

[0050] Specifically, Figure 1-Figure 3 As shown, preferably, a screw slide 5 is installed on the upper part of the cooling trough, and the screw slide 5 is arranged along the length direction of the cooling trough. A plurality of sliding seats 8 are arranged on the screw slide 5, and a shaping device is installed on the sliding seat 8. The screw slide 5 is driven by a first motor 9. When the first motor 9 rotates clockwise or counterclockwise, the screw of the screw slide 5 is driven to rotate clockwise or counterclockwise. The clockwise or counterclockwise rotation of the screw can drive the sliding seat 8 to reciprocate along the screw slide 5. The above is only a preferred case in the present application, and other structures can also be used to make the shaping device move synchronously or reset with the cable 2, such as an electric cylinder and a slide combination, a synchronous belt and a slide combination, etc.

[0051] Specifically, Figure 4 , Fig.10 As shown, a left connecting rod 19 and a right connecting rod 18 are fixed to the side of the sliding seat 8, and a shaping device is installed between the left connecting rod 19 and the right connecting rod 18. A driven gear ring 21 is fixed on the shaping device, and the driven gear ring 21 is meshed with a driving gear 20. The driving gear 20 is slidably installed on the driving shaft 15. The driving shaft 15 is provided with a limit strip along the length direction, and the driving gear 20 is provided with a corresponding limit groove, so that when the driving shaft 15 rotates, the driving gear 20 can be driven to rotate without affecting the reciprocating movement of the driving gear 20 along the length direction of the driving shaft 15. Sliding, the above is only a preferred case in the present application, and other structures can also be used to circumferentially limit the driving gear 20 and the driving shaft 15. For example, a limiting strip can be set inside the driving gear 20, and a bar-shaped limiting groove can be opened on the driving shaft 15. When the driving gear 20 is sleeved on the driving shaft 15, the limiting strip of the driving gear 20 extends into the limiting groove of the driving shaft 15 so that when the driving shaft 15 rotates, it will drive the driving gear 20 to rotate synchronously, and the driving gear 20 can move back and forth along the length direction of the driving shaft 15.

[0052] Preferably, annular extensions are provided on both sides of the driven gear ring 21, and both sides of the driving gear 20 extend into the annular extensions of the driven gear ring 21, so that when the shaping equipment moves synchronously with the sliding seat 8, it will drive the driving gear 20 to move synchronously together. It can be foreseen that in addition to the above structure, other limiting structures can also be used to enable the driving gear 20 to move synchronously with the driven gear ring 21 and the sliding seat 8. For example, a limiting rod can be provided on the side of the sliding seat 8, and the limiting rod is located on both sides of the driving gear 20, so that when the sliding seat 8 moves, it can drive the driving gear 20 to move synchronously.

[0053] Furthermore, the shaping equipment includes a ring sleeve, on the outside of which a plurality of cross bars 23 parallel to the cable 2 are rotatably mounted through bearings, the cross bar 23 is provided with a telescopic bracket facing the cable 2, and a shaping roller 22 is rotatably mounted on the movable end of the telescopic bracket, and a ratchet mechanism is also provided outside the ring sleeve, and a shift rack is provided on the rotating part of the ratchet mechanism, when the cross bar 23 rotates forward, the shaping roller 22 conforms to the surface of the cable 2 and rotates, the shift rod shifts the shift rack and the rotating part to rotate forward together, when the cross bar 23 rotates reversely, the rotating part is stuck, and the shift rod drives the movable end of the telescopic bracket and the shaping roller 22 to move along the shift rack in a direction away from the ring sleeve, and the shaping roller 22 is separated from the surface of the cable 2.

[0054] Preferably, in the present application, the ratchet mechanism includes an inner ratchet, and the rotating member is an outer ratchet, the outer ratchet is nested outside the inner ratchet, a shift rack is fixed on the outer ratchet, and a shift rod cooperating therewith is provided at the movable end of the telescopic bracket, and when the shift rod and the shift rack move relative to each other, the shift rod approaches or moves away from the ring sleeve, a plurality of the cross bars 23 are arranged around the cable 2, a driven gear ring 21 is fixed outside the cross bar 23, the driven gear ring 21 is meshed with the driving gear 20, a limiting ring is provided between the driving gear 20 and the driven gear ring 21, so that the driven gear ring 21 reciprocates with the driving gear 20, the driving gear 20 is provided on the driving shaft 15, and the driving gear 20 is circumferentially limited with the driving shaft 15, the driving shaft 15 is driven by a motor to rotate forward or reversely, and when the driving shaft 15 rotates forwardly, the shift rod moves along the shift rack toward the ring sleeve, and The outer ratchet can slide relative to the inner ratchet so that the shaping roller 22 fits the surface of the cable 2, and the outer ratchet can rotate with the cross bar 23. When the drive shaft 15 rotates in the opposite direction, the lever moves in the direction away from the ring sleeve, and the outer ratchet and the inner ratchet are stuck and motionless, so that the shaping roller 22 is away from the surface of the cable 2. When the shaping device is shaping, the shaping roller 22 fits and rotates with the surface of the cable 2. When the shaping device is reset, the shaping roller 22 is away from the surface of the cable 2. It can be foreseen that in addition to the above-mentioned ratchet mechanism, other one-way transmission mechanisms can also be used to cooperate to achieve this, so that when the lever rotates forward, the lever and the frame move synchronously, so that the telescopic bracket is not subjected to the force of moving away from the ring sleeve, and when the lever rotates reversely, the one-way transmission mechanism is stuck so that the lever is acted on by the frame to provide the telescopic bracket with a force away from the ring sleeve, so that the shaping roller 22 is separated from the cable 2, such as a one-way bearing or other structure.

[0055] Furthermore, a gear ring is provided on the surface of the ring sleeve, and a gear is provided on the end of the shaping roller 22, so that when the shaping equipment is shaping, the shaping roller 22 is in contact with the surface of the cable 2 while the gear is meshing with the gear ring. When the cross bar 23 rotates circumferentially, the gear and the gear ring move relative to each other, so that the gear rotates. The self-rotation of the gear causes the shaping roller 22 to rotate. By setting the gear ratio of the gear and the gear ring and the gear ratio of the driving gear 20 and the driven gear ring 21, the self-rotation speed of the shaping roller 22 can be adapted to the circumferential rotation speed of the shaping roller 22, so that no friction force in the tangential direction is generated between the shaping roller 22 and the surface of the cable 2.

[0056] Specifically, the shaping device is symmetrically provided with a left ring sleeve 41 and a right ring sleeve 32, and the left bearing 40, the left inner ratchet and the left gear ring 37 are installed on the left ring sleeve 41 from left to right in sequence, and the right gear ring 34, the right inner ratchet 45 and the right bearing 42 are installed on the right ring sleeve 32 from left to right in sequence. It can be foreseen that the above is a preferred example in the present application, and in actual use, it can also be installed by only one ring sleeve.

[0057] Specifically, Figure 4-Figure 6 As shown, the shaping device includes a left ring sleeve 41 fixedly connected to the left connecting rod 19, and a right ring sleeve 32 fixedly connected to the right connecting rod 18. A left bearing 40, a left inner ratchet and a left ring gear 37 are installed on the left ring sleeve 41 from left to right in sequence. A left mounting ring 39 is installed on the left bearing 40. A plurality of left mounting rods 44 are fixed on the outer wall of the left mounting ring 39. A left outer ratchet 38 is nested outside the left inner ratchet. A plurality of left shifting frames 27 are fixed on the outer wall of the left outer ratchet 38. A right ring gear 34, a right inner ratchet 45 and a right bearing 42 are installed on the right ring sleeve 32 from left to right in sequence. A right outer ratchet 33 is nested outside the right inner ratchet 45. The outer wall of the right outer ratchet 33 is fixed. There are multiple right shifting frames 29, a right mounting ring 31 is installed on the right bearing 42, multiple right mounting rods 43 are fixed on the outer wall of the right mounting ring 31, a cross bar 23 is fixed between the right mounting rod 43 and the left mounting rod 44, a left telescopic rod 24 and a right telescopic rod 25 facing the axial direction of the left ring sleeve 41 and the right ring sleeve 32 are fixed on the lower side of the cross bar 23, a shaping roller 22 is rotatably installed on the lower end of the left telescopic rod 24 and the right telescopic rod 25, a left gear 36 and a right gear 35 are respectively fixed on both ends of the rotating shaft of the shaping roller 22, when shaping, the left gear 36 is meshed with the left gear ring 37, and the right gear 35 is meshed with the right gear ring 34; and a driven gear ring 21 is fixed on the outside and inside of the cross bar 23.

[0058] like Figure 7As shown, the first right limiting ring 30 and the second right limiting ring 56 are arranged on both sides of the right inner ratchet 45, and the outer ratchet 57 is arranged on the outer side of the right inner ratchet 45, and the outer ratchet 57 is arranged between the first right limiting ring 30 and the second right limiting ring 56. The right outer ratchet 33 is nested on the outer side of the right inner ratchet 45, and the right outer ratchet 33 is located between the first right limiting ring 30 and the second right limiting ring 56. The inner side of the right outer ratchet 33 is provided with an inner ratchet 58, and the inner ratchet 58 cooperates with the outer ratchet 57. When the cable 2 is shaped, the inner ratchet 58 slides relative to the outer ratchet 57. At this time, the left outer ratchet 3 8. The right outer ratchet 33 rotates circumferentially together with the cross bar 23. When resetting is required, the cross bar 23 is driven by the second motor 10 to rotate in the opposite direction. The cross bar 23 rotates in the opposite direction, the inner ratchet 58 and the outer ratchet 57 engage with each other, the left outer ratchet 38, the right outer ratchet 33 and the left inner ratchet and the right inner ratchet 45 are stuck to each other, the left shift lever 26 and the left shift frame 27 move relative to each other, the right shift lever 28 and the right shift frame 29 move relative to each other, and the right shift lever 28 and the right shift frame 29 act simultaneously to lift the shaping roller 22 so that the shaping roller 22 is first separated from the cable 2, and then the shaping device is reset by the first motor 9.

[0059] Specifically, Figure 8 As shown, the inner bearing ring of the left bearing 40 is fixedly connected to the left ring sleeve 41, and the outer bearing ring of the left bearing 40 is fixedly connected to the left mounting ring 39, so that the left mounting ring 39 can rotate freely around the left ring sleeve 41, and four left mounting rods 44 are evenly fixed on the outer wall of the left mounting ring 39 at intervals, and the left mounting rods 44 are L-shaped. It can be foreseen that in addition to the above number, in actual production, multiple mounting rods can be set in the present application, such as two and symmetrically arranged, three and symmetrically arranged around the center of the ring sleeve, etc., so that each shaping roller 22 can operate stably during the circumferential rotation.

[0060] Specifically, Fig. 9 As shown, the fixed ends of the left telescopic rod 24 and the right telescopic rod 25 are fixed to one side of the ring sleeve at both ends of the cross bar 23, and the lower sides of the left telescopic rod 24 and the right telescopic rod 25 are connected with movable ends. The fixed ends and the movable ends of the left telescopic rod 24 and the right telescopic rod 25 are nested and connected, and springs are installed inside so that the movable ends of the left telescopic rod 24 and the right telescopic rod 25 can move upward or downward along the fixed ends.

[0061] During shaping, the second motor 10 drives the driving shaft 15 to rotate, the driving shaft 15 drives the driving gear 20 to rotate, the driving gear 20 drives the driven gear ring 21 to rotate, and the driven gear ring 21 drives the cross bar 23 to rotate circumferentially around the axis of the cable 2. At this time, multiple shaping rollers 22 are pressed on the surface of the cable 2 so that the shaping rollers 22 also move circumferentially around the surface of the cable 2. At the same time, the left gears 36 at both ends of the shaping rollers 22 are meshed with the left gear ring 37 on the left ring sleeve 41, and the right gear 35 is meshed with the right gear ring on the right ring sleeve 32. 34 meshes, so the shaping roller 22 will rotate in the same direction as the cross bar 23, and by setting the gear ratio between the gear and the gear ring and the gear ratio of the driving gear 20 and the driven gear ring 21, the rotation speed of the shaping roller 22 is matched with the circumferential rotation speed of the shaping roller 22, that is, when the shaping roller 22 rotates circumferentially at any angle, the shaping path length of the cable 2 surface is equal to the rotation path length of the shaping roller 22. Therefore, the shaping roller 22 will not generate a tangential force on the surface of the cable 2 during its rotation.

[0062] Preferably, a left lever 26 is fixed to the left side of the movable end of the left telescopic rod 24, a right lever 28 is fixed to the right side of the movable end of the right telescopic rod 25, and the left lever frame 27 is composed of two mutually parallel first left vertical rods, a second left vertical rod and a left inclined rod connected between the two vertical rods, wherein one end of the left inclined rod is close to the left ring sleeve 41, and the other end is far away from the left ring sleeve 41, the left lever 26 is located between the first left vertical rod and the second left vertical rod, and is located on the upper side or the lower side of the left inclined rod. Similarly, the right lever frame 29 is composed of two mutually parallel first right vertical rods 53, a second right vertical rod 55 and a right inclined rod 54 connected between the two vertical rods, wherein one end of the right inclined rod 54 is close to the right ring sleeve 32, and the other end is far away from the right ring sleeve 32. The right lever 28 is located between the first right vertical rod 53 and the second right vertical rod 55, and is located on the upper side or the lower side of the right inclined rod 54. It is foreseeable that other lever frame structures that can realize this action can also be set, such as a plate body, a groove is provided on the plate, and the lever extends into the groove, one end of the groove is close to the ring sleeve and the other end is away from the ring sleeve, so that when the lever and the groove move relative to each other, they can be close to the groove or away from the groove, etc., through the relative action of the groove on the lever, the shaping roller 22 is attached to the cable 2 or separated from the cable 2, the gear is engaged with or separated from the gear ring, and the gear is engaged with or separated from the gear ring through the elastic force and the action of the telescopic rod, and the gear and the gear ring will not be stuck.

[0063] When the shaping device needs to be reset, the shaping roller 22 must first be separated from the surface of the cable 2 so that the shaping roller 22 does not slide and rub against the cable 2 during the resetting process of the shaping device. When separated, the cross bar 23 is first driven to rotate in the opposite direction by the second motor 10 and the drive shaft 15. When the cross bar 23 rotates in the opposite direction, the left lever 26 drives the left outer ratchet 38 to rotate in the opposite direction until the left outer ratchet 38 is stuck with the left inner ratchet, and the right lever 28 drives the right outer ratchet 33 to rotate in the opposite direction until the right outer ratchet 33 is stuck with the right inner ratchet 45, so that the left lever frame 27 and the right lever frame 29 do not rotate with the cross bar 23. Therefore, when the left lever 26 and the right lever 28 continue to rotate in the opposite direction with the cross bar 23, the left lever 26 and the left tilt rod are relatively displaced, and the left lever 26 moves to The left tilting rod moves away from one end of the left ring sleeve 41, and the movable end of the left telescopic rod 24 moves away from the left ring sleeve 41 together with the left lever 26, and the right lever 28 and the right tilting rod 54 are relatively displaced, and the right lever 28 moves toward the right tilting rod 54 away from one end of the right ring sleeve 32, so that the movable end of the right telescopic rod 25 moves away from the right ring sleeve 32 together with the right lever 28. At this time, the shaping roller 22 is away from the left ring sleeve 41 and the right ring sleeve 32 and separates from the outer surface of the cable 2, so that when the shaping device moves in the opposite direction to the cable 2 during the resetting process, the shaping roller 22 is separated from the surface of the cable 2, so as to avoid the shaping roller 22 generating friction force on the surface of the cable 2 along the axial direction when the shaping device moves in the opposite direction to the cable 2, so as to avoid the outer sheath 60 being deformed and migrated due to the friction force.
