Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a stripping device for power cables. Background Technology

[0002] With the development of power technology, power cables are now an important component for power transmission. Power cables can be used to connect power equipment to ensure stable power transmission. Power cables are cables used to transmit and distribute high-power electrical energy. They consist of a core, insulation layer, shielding layer, and protective layer, and are mainly laid in urban underground power grids, power plant lead-out lines, and other scenarios.

[0003] Currently, when using power cables, since connectors need to be installed at the ends of the power cables, it is necessary to strip the power cables. The current stripping of cables is all done manually, which is inefficient and can easily damage the wire core. Some semi-automatic stripping equipment is cumbersome to operate and has low accuracy in stripping length.

[0004] Based on this, the present invention designs a wire stripping device for power cables to solve the above problems. Summary of the Invention

The sliding jaws are slidably connected to the T-shaped cylinder. A rectangular notch is provided on the T-shaped cylinder for the cross-cutting head to pass through.

[0014] Furthermore, the pressing mechanism includes four movable sliders that are slidably connected to the inner wall of the mounting frame. The inner walls of each pair of movable sliders are rotatably connected to both ends of the pressing roller. Both ends of the pressing roller are provided with dampers. The movable sliders are connected to the inner wall of the mounting frame through compression springs. It also includes two movable triangular blocks that are fixedly installed on the lead screw slider and cooperate with both ends of the pressing roller.

[0015] Furthermore, the tool setting mechanism includes a connecting column connected to an external moving drive. A moving frame is fixedly installed on the surface of the connecting column, and a fixed ring block is fixedly installed on the surface of the moving frame. A rotating ring plate is rotatably installed on the inner wall of the moving frame. The rotating ring plate is connected to an external rotating drive. The fixed ring block and the rotating ring plate cooperate with the linkage rod through U-shaped grooves and arc-shaped grooves opened on their surfaces, respectively. A linkage slider is fixedly installed on the surface of the linkage rod, and the linkage slider is slidably connected to the surface of the fixed ring block. A connecting frame is fixedly installed on the surface of the linkage rod, and the connecting frame is connected to two electromagnets through two limiting springs. Each electromagnet is connected to the cross-cutting head.

[0016] Furthermore, the rotating mechanism includes a movable column head fixedly mounted on a fixed ring block, and a sliding groove rotating cylinder rotatably connected to the inner wall of the mounting frame. The inner wall of the sliding groove rotating cylinder is provided with a lower straight groove, a spiral groove, and an upper straight groove that are sequentially and smoothly connected and cooperate with the movable column head.

[0017] Furthermore, the moving mechanism includes two moving motors fixedly installed on the inner wall of the mounting frame. Each moving motor has a moving lead screw fixedly installed at its output end. The moving lead screw and the lead screw slide form a helical pair transmission.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a moving mechanism to drive the rotary cutting head to rotate and feed into the cable during cutting. Since the cable is wrapped with a winding tape inside, when the rotary cutting head cuts to the position of the winding tape, the feedback action of the moving mechanism causes the rotary cutting head to stop feeding. At this time, the cutting is completed when the horizontal cutting head cuts to the vertical position of the rotary cutting head, thereby achieving the purpose of automatic and rapid cutting of the cable.

[0021] 2. This invention uses the electromagnetic action of the cutting mechanism to separate the two adjacent cross-cutting heads, thereby lifting the plastic sheath of the cable being cut. The cable pulling mechanism no longer fixes one end of the cable, and the cable is pulled out by the external gripping device. The plastic sheath is separated from the wire core by the blocking action of the rotary cutting head, thereby achieving the purpose of stable stripping. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0035] like Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, in one embodiment, a wire stripping device for power cables is provided, the device comprising:

[0036] Wire stripping box 1: It is equipped with a mounting frame 101;

[0037] The wire stripping mechanism 2 includes four transverse cutting heads 201 mounted on the mounting frame 101 for transverse cutting of the cable, and two rotary cutting heads 202 mounted on the mounting frame 101 for circumferential cutting of the cable.

[0038] Cable pulling mechanism 3: Used to fix the cut end of the cable;

[0039] Wire clamping mechanism 4: Straightens the cable by cooperating with wire pulling mechanism 3;

[0040] Tool setting mechanism 5: used to drive the cross-cutting head 201 to move laterally;

[0041] Rotation mechanism 6: It drives the rotary cutting head 202 to rotate by cooperating with the tool setting mechanism 5 and the moving mechanism 7.

[0042] In practical applications, when performing wire stripping operations, as in the embodiments of the present invention... Figure 5 As shown, at this time, one end of the cable is inserted into the cable pulling mechanism 3 by an external gripping device. The cable pulling mechanism 3 fixes one end of the cable, and then pulls the cable into the mounting frame 101. Figure 1 As shown, the cable is guided by the wire pressing mechanism 4, and the resistance of the wire pressing mechanism 4 straightens the cable between the wire pressing mechanism 4 and the wire pulling mechanism 3, ensuring the quality of subsequent stripping. When the cable is pulled by the wire pulling mechanism 3 and passes under the rotary cutter head 202, the distance measurement begins. When the set distance is reached, the wire pulling mechanism 3 stops pulling the cable input. Figure 10 As shown, the cutting depth of the cross-cutting head 201 is adjusted by the action of the tool setting mechanism 5, such as... Figure 7 and Figure 9 As shown, the moving mechanism 7 simultaneously drives the rotary cutting head 202 to press against the cable. After completion, the cutting mechanism 5 drives the horizontal cutting head 201 to perform a horizontal cut on the cable. While the horizontal cutting head 201 is cutting the cable horizontally, the working mechanism 5 and the rotating mechanism 6 drive the rotary cutting head 202 to rotate. Simultaneously, the moving mechanism 7 drives the rotary cutting head 202 to feed into the cable as it rotates and cuts. Since the cable is wrapped with a winding tape, when the rotary cutting head 202 cuts to the winding tape position, the feedback from the moving mechanism 7 stops the rotary cutting head 202 from feeding further. The cutting is completed when the horizontal cutting head 201 reaches the vertical position of the rotary cutting head 202, thus achieving automatic and rapid cable cutting. When the horizontal cutting head 201 stops at the position of the rotary cutting head 202, as... Figure 10 As shown, at this time, the electromagnetic action of the cutting mechanism 5 separates the two adjacent cross-cutting heads 201, thereby lifting the plastic sheath of the cable being cut. The cable pulling mechanism 3 no longer fixes one end of the cable, and the cable is pulled out by the external gripping device. The plastic sheath is separated from the wire core by the blocking action of the rotary cutting head 202, thereby achieving the purpose of stable stripping.

[0043] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the wire pulling mechanism 3 includes two drive motors 308 fixedly mounted on the mounting frame 101. Each drive motor 308 has a drive screw 307 fixedly mounted at its output end. The drive screw 307 and the screw slider 306 form a helical transmission pair. The screw slider 306 is slidably connected to the surface of the mounting frame 101. The surfaces of the two screw sliders 306 are fixedly connected to the wire pulling rod 301. A T-shaped cylinder 302 is fixedly mounted on the surface of the wire pulling rod 301. A clamping motor 303 is fixedly mounted on the surface of the T-shaped cylinder 302. The output end of the clamping motor 303 passes through the T-shaped cylinder 302 and is rotatably connected to the T-shaped cylinder 302. A clamping screw 304 is fixedly mounted on the output end of the clamping motor 303. The clamping screw 304 and two sliding jaws 305 form opposite helical transmission pairs. The sliding jaws 305 are slidably connected to the T-shaped cylinder 302. A rectangular notch is provided on the T-shaped cylinder 302 for the cross-cutting head 201 to pass through.

[0044] In practical application, when stripping cables, one end of the cable is inserted into the T-shaped cylinder 302 using an external gripping device. The clamping motor 303 drives the clamping screw 304 to rotate, which in turn drives two sliding jaws 305 to move towards each other via a helical transmission, thereby fixing one end of the cable. After fixing, as... Figure 1As shown, at this time, the operation of the drive motor 308 drives the drive screw 307 to rotate, and then drives the screw slider 306 to move horizontally to the end away from the drive motor 308 through the screw pair transmission. The movement of the screw slider 306 drives the cable to move into the mounting frame 101 through the pull rod 301, thereby achieving the purpose of automatically pulling the cable horizontally.

[0045] like Figure 1 As shown, in another preferred embodiment of the present invention, the pressing mechanism 4 includes four movable sliders 403 that are slidably connected to the inner wall of the mounting frame 101. The inner walls of each pair of movable sliders 403 are rotatably connected to both ends of the pressing roller 402, and dampers are provided at both ends of the pressing roller 402. The movable sliders 403 are connected to the inner wall of the mounting frame 101 through compression springs 404. It also includes two movable triangular blocks 401 that are fixedly installed on the screw slider 306 and cooperate with both ends of the pressing roller 402. Rubber rings 405 are fixedly installed on the surface of the pressing roller 402.

[0046] In practical applications, the embodiments of the present invention, such as Figure 1 As shown, when the pull rod 301 pulls the cable to move horizontally, the lead screw slider 306 drives the moving triangular block 401 to move horizontally away from the drive motor 308. Through the cooperation of the moving triangular block 401 and the pressure roller 402, the pressure roller 402 squeezes the cable under the action of the compression spring 404. At the same time, the damper on the pressure roller 402 increases the resistance to the cable, thereby straightening the cable through the pulling force of the pull mechanism 3, achieving the purpose of precise cutting of the cable.

[0047] like Figure 10 As shown, in another preferred embodiment of the present invention, the tool setting mechanism 5 includes a connecting column 501 connected to an external moving drive. A moving frame 502 is fixedly installed on the surface of the connecting column 501. A fixed ring block 503 is fixedly installed on the surface of the moving frame 502. A rotating ring plate 504 is rotatably installed on the inner wall of the moving frame 502. The rotating ring plate 504 is connected to an external rotating drive. The fixed ring block 503 and the rotating ring plate 504 respectively cooperate with the linkage rod 505 through U-shaped grooves and arc-shaped grooves opened on their surfaces. A linkage slider 506 is fixedly installed on the surface of the linkage rod 505. The linkage slider 506 is slidably connected to the surface of the fixed ring block 503. A connecting frame 507 is fixedly installed on the surface of the linkage rod 505. The connecting frame 507 is connected to two electromagnets 509 through two limiting springs 508. Each electromagnet 509 is connected to the cross-cutting head 201.

[0048] In practical applications, when the cable is pulled to the set cutting distance by the cable pulling mechanism 3, as in the embodiments of the present invention... Figure 10As shown, at this time, the rotating ring plate 504 is driven to rotate by an external rotation drive. The rotation of the rotating ring plate 504, through the combined action of the arc groove on it and the U-shaped groove on the fixed ring block 503, drives the linkage rod 505 to move towards the central axis of the fixed ring block 503. Then, through the connecting frame 507 and the electromagnet 509, the cross-cutting head 201 moves towards the central axis of the fixed ring block 503. When the cross-cutting head 201 moves to the cutting position, the rotating ring plate 504 stops rotating. At this time, the connecting column 501 is driven to move horizontally by an external movement drive. Then, through the blade setting mechanism 5, the cross-cutting head 201 moves horizontally. At this time, the cross-cutting head 201 cuts the cable horizontally, thereby achieving the purpose of automatically cutting the cable horizontally. After the cable has completed horizontal cutting and ring cutting, the current direction of one of the two electromagnets 509 that are in contact with each other changes, causing the two electromagnets 509 to move in opposite directions. This causes the two cross-cutting heads 201 to separate from each other, lifting up the plastic sheath of the cable, thereby improving the stability of stripping.

[0049] like Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the rotating mechanism 6 includes a movable column head 601 fixedly installed on the fixed ring block 503, and a sliding groove rotating cylinder 602 rotatably connected to the inner wall of the mounting frame 101. The inner wall of the sliding groove rotating cylinder 602 is provided with a lower straight groove 603, a spiral groove 604 and an upper straight groove 605 that are sequentially and smoothly connected and cooperate with the movable column head 601.

[0050] In practical application, when the moving frame 502 drives the cross-cutting head 201 to move horizontally, the fixed ring block 503 drives the moving column head 601 to move horizontally. Due to the action of the moving mechanism 7, the rotary cutting head 202 is pressed against the cable. Figure 6 As shown, at this time, the sliding drum 602 is driven to rotate by the cooperation between the movable column head 601 and the spiral groove 604, as... Figure 7 As shown, the rotation of the chute drum 602 drives the moving mechanism 7 to rotate synchronously, which in turn drives the rotary cutting head 202 to rotate. At this time, in conjunction with the feed motion of the moving mechanism 7, the rotary cutting head 202 performs a circular cut on the cable, thereby achieving the purpose of completing the circular cut on the cable while performing horizontal cutting, thus increasing the cutting efficiency.

[0051] like Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, in another preferred embodiment of the present invention, the moving mechanism 7 includes two moving motors 701 fixedly installed on the inner wall of the mounting frame 101. Each moving motor 701 has a moving lead screw 702 fixedly installed at its output end. The moving lead screw 702 and the lead screw slide 703 form a helical transmission pair. A linkage slide 704 is rotatably installed on the surface of the lead screw slide 703. The linkage slide 704 is rotatably connected to the slide groove rotating cylinder 602. Two slide groove columns 705 are fixedly installed on the inner wall of the linkage slide 704. A pressure rotating cylinder 706 is rotatably installed on the surface of the slide groove rotating cylinder 602. The surface of the pressure rotating cylinder 706 has... An arc-shaped slide 707 that mates with the slide column head 705; two proximal sliders 708 fixedly installed on the inner wall of the pressure cylinder 706; a connecting sleeve 711 penetrating the surface of the slide cylinder 602 and slidably connected to the connecting sleeve 711; a pressure-bearing column 709 that mates with the proximal slider 708 slidably installed on the inner wall of the connecting sleeve 711; the pressure-bearing column 709 and the connecting sleeve 711 are connected by a connecting spring 710; an upper contact 712 and a lower contact 713 that mate with each other are fixedly installed on the surface of the pressure-bearing column 709 and the inner wall of the connecting sleeve 711, respectively; and a rotary cutting head 202 fixedly installed on the surface of the connecting sleeve 711.

[0052] In practical applications, when adjusting the cutting distance of the cross-cutting head 201, as in the embodiments of the present invention... Figure 3 As shown, at this time, the moving motor 701 starts running. The movement of the moving motor 701 drives the moving lead screw 702 to rotate, which in turn drives the lead screw slide 703 to move horizontally away from the moving motor 701 through the screw pair transmission. At this time, the lead screw slide 703 pushes the linkage slide 704 to move horizontally away from the moving motor 701, as shown. Figure 7 and Figure 9 As shown, the linkage slide cylinder 704 drives the slide column head 705 to move in the arc-shaped slide groove 707, which in turn drives the pressure rotary cylinder 706 to rotate. The rotation of the pressure rotary cylinder 706 drives the near-center slider 708 to rotate synchronously. Through the cooperation of the near-center slider 708 and the pressure column 709, the pressure column 709 is driven to move vertically downward. The pressure column 709 drives the connecting sleeve 711 to move vertically downward synchronously, thereby causing the rotary cutting head 202 to press against the cable surface. When the connecting spring 710 is compressed, the upper contact 712 and the lower contact 712 are pressed together. After contact 713 makes contact, the moving motor 701 stops running. When the chute drum 602 rotates and drives the connecting sleeve 711 to rotate synchronously, the moving motor 701 starts running, driving the rotary cutter head 202 to feed into the cable. When it cuts to the position of the inner winding tape of the cable, due to the low rigidity of the winding tape, the rotary cutter head 202 will move downward instantly, causing the upper contact 712 to disengage from the lower contact 713. At this time, the moving motor 701 stops running, thereby achieving the purpose of automatically and accurately circumferentially cutting the cable.

[0053] like Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the mating ends of the sliding column head 705 and the arc-shaped sliding groove 707 are provided with rotating balls, the mating ends of the pressure column 709 and the near-center slider 708 are also provided with rotating balls, and the mating ends of the moving column head 601 and the lower straight groove 603, the spiral groove 604 and the upper straight groove 605 are also provided with rotating balls.

[0054] In practical applications, the rotating ball in this invention increases the stability of motion and converts sliding friction into rolling friction, thereby improving the service life of parts.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
