Description

Technical Field

[0001] The invention relates to the technical field related to data cable production, in particular to a die-cutting machine for data cable production. Background Art

[0002] As is known, a data cable is a cable that connects electronic devices and transmits data or power. According to different functions and interface types, there are many classifications and specifications of data cables, such as USB data cables, HDMI data cables, Lightning data cables, network cables, and audio cables.

[0003] In the production process of data cables, it is necessary to cut a longer roll of wire into multiple fixed-length wires. For example, the patent with announcement number CN217451930U and announcement date September 20, 2022, titled "A die-cutting machine for data cable production", includes a workbench, and support plates are provided on the left and right directions of the rear upper end of the workbench. The same work box is provided on the two support plates, and a track is provided at the bottom of the work box. A fixed rod is provided in the track, and the upper end of the fixed rod is fixedly connected to the bottom of the threaded block, and a No. 1 telescopic rod is provided at the lower end of the fixed rod. A limit block is provided at the lower end of the No. 1 telescopic rod, and die-cutting knives are provided at both ends of the limit block. The die-cutting work is achieved through the limit block, the die-cutting knife and the No. 1 telescopic rod. The rotation of the semi-finished data cable is achieved through the No. 1 wheel, the No. 2 gear, the No. 1 motor and the swivel ring to make the die-cutting area larger. The straightening and fixing of the semi-finished data cable is achieved through the No. 2 telescopic rod, the connecting rod and the plastic clamp ring. The No. 1 telescopic rod can move left and right through the No. 2 motor, the threaded rod, the threaded block and the track, thereby improving the efficiency of die-cutting.

[0004] The shortcoming of the existing technology is that it is difficult to complete the die-cutting removal of the insulation at the end of the wire after cutting to a fixed length and the removal of the insulation of multiple inner wires at one time. It requires at least two steps to complete, which seriously affects the production efficiency of the data cable and the production cost of the data cable will also be high. Summary of the invention

[0005] The purpose of the present invention is to provide a die-cutting machine for data cable production to solve the technical problems in the related art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A die-cutting machine for data cable production comprises a driving assembly and two sets of wire-rubbing plates; each set of wire-rubbing plates is provided with a corresponding set of die-cutting knives, and a transmission assembly is provided between the two sets; removing the insulation skin at the end of the wire comprises two strokes: in the first stroke, the two sets of wire-rubbing plates rub the wire to rotate simultaneously based on the driving action of the driving assembly, and each set of die-cutting knives die-cuts the outer insulation skin of the wire based on the power of the corresponding set of wire-rubbing plates; in the second stroke, the wire is pulled so that its two ends are close to each other, and the die-cutting knives prevent the insulation skin at the end of the wire from moving with the wire after die-cutting, and after the two sets of wire-rubbing plates contact multiple wires inside the wire, the multiple wires are flattened based on the driving action of the driving assembly, and then the two sets of wire-rubbing plates rub the multiple wires to rotate, and each set of die-cutting knives die-cuts the inner insulation skin of the wire based on the power of the corresponding set of wire-rubbing plates.

[0008] As mentioned above, a wire rolling roller is provided on the surface of the wire rolling plate in contact with the wire material, and the axial direction of the wire rolling roller is perpendicular to the length direction of the wire material.

[0009] The above also includes two groups of pressing plates, and each group of die-cutting knives is arranged between a corresponding group of wire-rubbing plates and a group of pressing plates, and the two groups of pressing plates press the two ends of the wire based on the driving force of the driving assembly; the corresponding group of wire-rubbing plates and a group of pressing plates are connected by a first elastic member, and the position of each group of pressing plates is fixed. In the process of the two groups of die-cutting knives die-cutting the inner insulation skin of the wire based on the power of the two groups of wire-rubbing plates, the two groups of wire-rubbing plates move with the wire, and after the inner insulation skin is cut off, the two groups of wire-rubbing plates are reset based on the rebound force of the corresponding first elastic member.

[0010] As mentioned above, a pressing roller is provided on the surface of the pressing plate in contact with the wire, and the axial direction of the pressing roller is parallel to the length direction of the wire.

[0011] As mentioned above, the transmission assembly includes multiple first support rods, each wire-rubbing board is connected to a corresponding first support rod, each first support rod is slidably connected to the corresponding die-cutting knife seat, and a second elastic member is provided between the two, and a pressure plate is provided on the knife seat of each die-cutting knife, and each of the wire-rubbing boards is provided with an extrusion block. In the process of each group of wire-rubbing boards rubbing the wire, the extrusion block on each wire-rubbing board squeezes the pressure plate at the corresponding position to drive the die-cutting knife to cut the insulation skin.

[0012] As mentioned above, the pressure plate is divided into an inclined section and a horizontal section. When the die-cutting knife is driven to die-cut the insulation skin, the extrusion block moves from the low end to the high end of the inclined section, and the high end of the inclined section is connected to the horizontal section. The height difference dimension of the inclined section is the same as the thickness dimension of the outer insulation skin of the wire.

[0013] As mentioned above, the blade of the die-cutting knife is in the shape of comb teeth, and the portion between two adjacent comb teeth is semicircular, and the radial dimension is consistent with the radial dimension of the metal core material of the wire.

[0014] As mentioned above, the number of the semicircular parts between two adjacent comb teeth is greater than the number of the conductors in the wire.

[0015] As mentioned above, a second support rod is provided on the pressing plate for sliding along the pressing direction, and a third elastic member is provided between the second support rod and the pressing plate in the sliding direction. The pressing plate transmits the power of the second support rod based on the third elastic member to press the end of the wire.

[0016] As mentioned above, the wire rubbing plate must also be provided with a slider, and in the sliding direction, a fourth elastic member is provided between the slider and the wire rubbing plate, and the wire rubbing roller is provided on the slider at the corresponding position. When the rubbing wire rotates, the sliding of the slider on the corresponding wire rubbing plate in the direction away from the wire is restricted. When the conductor inside the rubbing wire rotates, the sliding of the slider on the corresponding wire rubbing plate in the direction away from the wire is also restricted.

[0017] The beneficial effect of the present invention is that through the cooperation of two sets of wire rubbing plates and two sets of die-cutting knives, the insulation of multiple inner wires can be die-cut and removed during the process of removing the outer insulation of the wire after die-cutting, so the removal process of the inner and outer insulation layers of the wire ends is reduced, which can not only effectively improve the production efficiency of the data cable, but also save production costs.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 5 The present invention is further described in detail.

[0027] An embodiment of the present invention provides a die-cutting machine for data cable production, including a drive assembly 2 and two groups of wire-rubbing plates 3; each group of wire-rubbing plates 3 is correspondingly provided with a group of die-cutting knives 4, and a transmission component is provided between the two; removing the insulation skin 10 at the end of the wire 1 includes two strokes: in the first stroke, the two groups of wire-rubbing plates 3 simultaneously rub the wire 1 to rotate based on the driving action of the drive assembly 2, and each group of die-cutting knives 4 die-cuts the outer insulation skin 10 of the wire 1 based on the power of the corresponding group of wire-rubbing plates 3; in the second stroke, the wire 1 is pulled so that its two ends are close to each other, and the die-cutting knife 4 prevents the insulation skin 10 at the end of the wire 1 from moving with the wire 1 after die-cutting. After the two groups of wire-rubbing plates 3 contact multiple wires inside the wire 1, the multiple wires are flattened based on the driving action of the drive assembly 2, and then the two groups of wire-rubbing plates 3 rub the multiple wires to rotate, and each group of die-cutting knives 4 die-cuts the inner insulation skin 10 of the wire 1 based on the power of the corresponding group of wire-rubbing plates 3.

[0028] Specifically, the data cable as a whole includes a fixed-length wire 1 and interfaces provided at both ends of the wire 1, wherein before the wire 1 is connected to the interface, it is necessary to remove the outer insulating skin 10 of the end of the wire 1 and the insulating skin 10 of the multiple internal wires, and then weld the metal core material 11 leaking from the end of the wire 1 to the interface, while in the prior art, it is difficult to complete the die-cutting removal of the insulating skin 10 at the end of the wire 1 after fixed-length cutting and the removal of the insulating skin 10 of the multiple inner wires at one time, and at least two processes are required to complete, which seriously affects the production efficiency of the data cable, and the production cost of the data cable will also be high.

[0029] In this embodiment, the die-cutting machine used can solve the above problem, that is, the wire-rubbing board 3 is a long plate-shaped structure, and the length dimension is much larger than the circumference dimension of the outer insulating skin 10 of the wire 1. There are two wire-rubbing boards 3 in each group, and the two groups of wire-rubbing boards 3 are placed at both ends of the wire 1. Each group of wire-rubbing boards 3 is symmetrically arranged up and down at the end of the die-cut wire 1, which can support the die-cut wire 1. Each group of two wire-rubbing boards 3 can realize the rubbing of the wire 1 through relative movement, that is, the driving assembly 2 can drive the two wire-rubbing boards 3 to move relative to each other along their respective length directions (that is, the horizontal direction). In this way, the driving assembly 2 can include a screw transmission mechanism, and each wire-rubbing board 3 is correspondingly connected to a screw transmission mechanism , and the wire rubbing plate 3 needs to contact the wire 1 before it can be rubbed. In this way, the driving assembly 2 also includes a power mechanism that drives each group of two wire rubbing plates 3 to approach each other in the vertical direction. The power mechanism can also select a screw transmission mechanism, so that the two wire rubbing plates 3 can be driven vertically to approach each other and contact the wire 1, and then the two wire rubbing plates 3 are driven horizontally to move relative to each other to rub the wire 1. In addition, the number of die-cutting knives 4 in each group is also two, and each die-cutting knife 4 corresponds to a wire rubbing plate 3, and a transmission component is provided between the two, that is, when the wire rubbing plate 3 is rubbing the wire 1, the transmission component can transmit power to the die-cutting knife 4, so that the die-cutting knife 4 can die-cut the insulating skin 10 of the wire 1.

[0030] During operation, the insulating skin 10 of the outer layer of the wire 1 must be removed first, that is, the driving assembly 2 first drives each group of two rubbing plates 3 to approach each other vertically to compress the wire 1, and then the driving assembly 2 drives each group of two rubbing plates 3 to move relatively in the horizontal direction to rub the wire 1, so that the wire 1 rotates. In this process, each rubbing plate 3 transmits power to the corresponding die-cutting knife 4 through the transmission mechanism, so that the blade of the die-cutting knife 4 gradually cuts the insulating skin 10 of the outer layer of the wire 1 until the insulating skin 10 is cut off, and then the rubbing plate 3 stops rubbing the wire 1, and pulls the wire 1 through external force to move the end of the wire 1 in the direction of separating from the rubbing plate 3. In this process, since the position of the die-cutting knife 4 remains unchanged, the insulating skin 10 after the end of the wire 1 is cut off is hindered, so that the cut insulating skin 10 is gradually Separated from the wire 1, when the multiple wires inside the wire 1 are aligned with the wire rubbing board 3 up and down, the driving assembly 2 drives each group of two wire rubbing boards 3 to continue to approach vertically to press the bundled multiple wires, so that the multiple wires are gradually flattened, and then the driving assembly 2 drives each group of two wire rubbing boards 3 to move relatively in the horizontal direction to rub the multiple wires. At this time, the wire 1 continues to be driven away from the wire rubbing board 3, so that the die-cutter 4 not only die-cuts the insulation skin 10 of multiple wires based on the power of the corresponding wire rubbing board 3, but also generates a thrust for the insulation skin 10 to be cut off. After the insulation skin 10 of each wire is cut off, the wire rubbing board 3 stops, the die-cutter 4 keeps its position unchanged, and the wire 1 continues to move, then the insulation skin 10 of the outer layer of the wire 1 and the insulation skin 10 of each inner wire will be driven off.

[0031] The beneficial effect of this embodiment is that through the cooperation of two sets of wire rolling plates 3 and two sets of die-cutting knives 4, the insulation skins 10 of multiple inner wires can be die-cut and removed during the process of removing the outer insulation skin 10 of the wire 1 after die-cutting, so the removal process of the inner and outer insulation skins 10 at the end of the wire 1 is reduced, which can not only effectively improve the production efficiency of the data cable, but also save production costs.

[0032] Preferably, a wire rolling roller 30 is provided on the surface of the wire rolling board 3 in contact with the wire 1, and the axial direction of the wire rolling roller 30 is perpendicular to the length direction of the wire 1; specifically, in the process of the wire 1 being driven by an external force to move in a direction away from the wire rolling board 3, there is friction resistance between the wire rolling board 3 and the outer insulating skin 10 of the wire 1, which can easily cause pulling damage to the wire 1. Therefore, a wire rolling roller 30 is provided on the surface of the wire rolling board 3 in contact with the wire 1. The arrangement of the wire rolling roller 30 can provide friction for the rotation of the wire 1, and can reduce the friction resistance for the wire 1 to move away from the wire rolling board 3.

[0033] In the subsequent description, the rubbing of the wire 1, the conductor and the metal core material 11 by the wire rubbing board 3 is that the wire rubbing board 3 drives the wire rubbing roller 30 arranged thereon to contact the wire 1, the conductor and the metal core material 11. For the convenience of description and understanding, the subsequent description is mainly based on the rubbing of the wire 1, the conductor and the metal core material 11 by the wire rubbing board 3.

[0034] Furthermore, it also includes two groups of pressing plates 5, and each group of die-cutting knives 4 is arranged between a corresponding group of wire-rubbing plates 3 and a group of pressing plates 5, and the two groups of pressing plates 5 press the two ends of the wire 1 based on the driving force of the driving assembly 2; the corresponding group of wire-rubbing plates 3 and a group of pressing plates 5 are connected by a first elastic member, and the position of each group of pressing plates 5 is fixed. In the process of the two groups of die-cutting knives 4 die-cutting the inner insulating skin 10 of the wire 1 based on the power of the two groups of wire-rubbing plates 3, the two groups of wire-rubbing plates 3 move with the wire 1, and after the inner insulating skin 10 is cut off, the two groups of wire-rubbing plates 3 are reset based on the rebound force of the corresponding first elastic member.

[0035] Specifically, in the aforementioned embodiment, the outer insulating skin 10 of the wire 1 is removed by the obstruction of the die cutter 4. When the die cutter 4 is cutting the insulating skin 10 on the inner conductor of the wire 1, the wire 1 is moving as a whole, and the die cutter 4 does not move with it, which will cause the insulating skin 10 to not be completely cut off, and part of it will be scraped off. The friction between the insulating skin 10 and the metal core material 11 is relatively large. If the insulating skin 10 is not completely cut off, it will be subjected to tension. The metal core material 11 of the conductor is composed of multiple thin wires, which can easily cause the metal core material 11 inside the conductor to break.

[0036] Therefore, in this embodiment, in order to solve the above-mentioned problem, two groups of pressing plates 5 are further provided. The number of each group of pressing plates 5 is two, and they are block-shaped structures. Each pressing plate 5 corresponds to a wire-rubbing plate 3. The corresponding pressing plate 5, wire-rubbing plate 3 and die-cutting knife 4 have a positional relationship in which the pressing plate 5 is closer to the end of the wire 1, and the die-cutting knife 4 is located between the pressing plate 5 and the wire-rubbing plate 3. The two groups of pressing plates 5 press the two ends of the wire 1 respectively through the drive assembly 2, that is, a wire rod transmission mechanism can be separately provided, wherein the positions of the two groups of pressing plates 5 can be fixed on the workbench, and the positions of the two groups of wire-rubbing plates 3 and the two groups of die-cutting knives 4 are moved together, that is, each group of wire-rubbing plates 3 and the corresponding group of die-cutting knives 4 are synchronized when moving. The wire 1 is pressed by the two groups of pressing plates 5, and the two groups of pressing plates 5 are pressed by the two groups of pressing plates 5. In order to rub the wire 1 to rotate, a pressing roller 50 is provided on the contact surface of the pressing plate 5 with the wire 1, and the axial direction of the pressing roller 50 is parallel to the length direction of the wire 1, that is, the two groups of pressing plates 5 press the two ends of the wire 1, and the wire 1 can be rubbed normally by the two groups of wire-rubbing plates 3, and when the wire 1 is pulled to move in a direction away from the wire-rubbing plates 3, the two ends of the wire 1 are restricted by the two groups of pressing plates 5. Therefore, after the outer insulating sheath 10 of the wire 1 is die-cut and cut off, the wire 1 is pulled by external force to move in a direction away from the wire-rubbing plates 3 (that is, away from the wire-rubbing plates 3 in its own length direction). Since the outer insulating sheaths 10 at the two ends of the wire 1 are pressed by the two groups of pressing plates 5, the cut insulating sheaths 10 gradually separate from the wire 1 as the wire 1 moves, and in this process During the process, as the cut insulation 10 gradually separates from the wire 1, multiple wires inside the wire 1 will also be exposed. When the multiple wires are aligned with the wire rolling plates 3, the drive assembly 2 drives the two sets of wire rolling plates 3 again to press the multiple wires at the corresponding positions, so that the bundled multiple wires are gradually flattened. At the same time, the two sets of pressing plates 5 continue to press the cut insulation 10 (at this time the insulation 10 has not completely separated from the wire 1). After the multiple wires are flattened, the two sets of wire rolling plates 3 begin to rub the multiple wires at the corresponding positions to rotate, and each set of die-cutters 4 can also die-cut the insulation 10 on the surface of the wire. When the blade of the die-cutter 4 cuts into the insulation 10 of the wire, since the wire is moving, the insulation 10 of the wire is based on a pulling force of the die-cutter 4.The die cutter 4 moves along with the wire (that is, along with the wire 1). During this process, the elastic force of the first elastic member gradually increases. When the wire insulation 10 is cut, the tension given to the die cutter 4 by the wire is not enough to overcome the elastic force of the first elastic member. Therefore, under the action of the rebound force of the first elastic member, the die cutter 4 moves in the direction opposite to the moving direction of the wire 1 and gradually pushes the cut insulation 10 away from the wire. How can we avoid the problem that the insulation 10 is not completely cut off and is subjected to tension, causing the metal core 11 inside the wire to break?

[0037] During the process of die-cutting the wire insulation 10 by the die-cutting knife 4, the insulation 10 cut off from the outer layer of the wire 1 has not completely separated from the end of the wire. Therefore, when the bundled wires are flattened by a group of wire rolling plates 3 at the corresponding positions, the two sides of the flattening position are still concentrated in the bundle. This can avoid the situation where multiple bundled wires are scattered and offset when they are flattened, so that when the die-cutting knife 4 die-cuts later, the die-cut lengths of the insulation 10 of multiple wires can be basically kept consistent.

[0038] Preferably, the transmission assembly includes a plurality of first support rods 6, each wire-rubbing board 3 is connected to a corresponding first support rod 6, each first support rod 6 is slidably connected to the corresponding tool holder of the die-cutting knife 4, and a second elastic member is provided between the two, and a pressure plate 7 is provided on the tool holder of each die-cutting knife 4, and each of the wire-rubbing boards 3 is provided with an extrusion block. In the process of each group of wire-rubbing boards 3 rubbing the wire 1, the extrusion block on each wire-rubbing board 3 squeezes the pressure plate 7 at the corresponding position to drive the die-cutting knife 4 to die-cut the insulating skin 10.

[0039] Specifically, the sliding direction between the die-cutting knife 4 and the corresponding first support rod 6 is parallel to the vertical direction. In the process of each group of wire-rubbing plates 3 being driven to approach each other vertically to compress the wire 1, the first support rod 6 moves together with the corresponding wire-rubbing plates 3, and the first support rod 6 will transmit power to the corresponding die-cutting knife 4 through the second elastic member. In this way, in the process of each group of wire-rubbing plates 3 compressing the wire 1, the corresponding group of die-cutting knives 4 will gradually approach the wire 1. When each group of wire-rubbing plates 3 rubs the wire 1 (or multiple wires) to rotate, the movement of the wire-rubbing plates 3 will drive the extrusion block to squeeze the pressure plate 7 at the corresponding position, so that the pressure plate 7 drives the die-cutting knife 4 to gradually cut into the insulating skin 10. The depth of the die-cutting knife 4 cutting into the insulating skin 10 should also be controlled to avoid The wire insulation 10 inside the cutter, therefore, in a further embodiment, the pressure plate 7 is divided into an inclined section 70 and a horizontal section 71. In the process of the die-cutting knife 4 being driven to die-cut the insulation 10, the extrusion block moves from the low end to the high end of the inclined section 70, and the high end of the inclined section 70 is connected to the horizontal section 71. The height difference dimension of the inclined section 70 is the same as the thickness dimension of the outer insulation 10 of the wire 1. In this way, in the process of the extrusion block moving from the low end to the high end along the inclined section 70, the corresponding die-cutting knife 4 can gradually cut into the outer insulation 10 of the wire 1. After the extrusion block reaches the horizontal section 71, the cutting depth of the die-cutting knife 4 no longer changes. At this time, the extrusion block continues to move in the horizontal section 71, and the outer insulation 10 of the wire 1 will also be completely cut off.

[0040] Similarly, when die-cutting the wire insulation 10 inside the wire 1, the cutting depth of the die-cutting knife 4 should also be ensured to avoid cutting the metal core 11. In a further embodiment, the blade of the die-cutting knife 4 is in the shape of comb teeth, and the part between two adjacent comb teeth is semicircular, and the radial dimension is consistent with the radial dimension of the metal core 11 of the wire 1. That is, in the process of each group of wire-rubbing plates 3 flattening the bundled multiple wires and rubbing the multiple wires to rotate, as the extrusion block moves in the inclined section 70, each group of die-cutting knives 4 also cuts into the insulation 10 of the wire. When the blades of the two die-cutting knives 4 in each group are in contact, the corresponding semicircular parts at the blades of the two die-cutting knives 4 form a complete corresponding gap. The die-cutting knife 4 is a full circle, and the radial dimension of the circle is the same as the radial dimension of the metal core material 11. The cutting depth of each group of two die-cutting knives 4 is limited to avoid cutting the metal core material 11 while cutting the insulating skin 10 of the wire. The comb-shaped die-cutting knife 4 can also play a combing role when contacting multiple wires at corresponding positions, so that the multiple wires that have been flattened are separated by a certain distance between two adjacent wires, so that the insulating skin 10 is cut off without affecting each other, and the separation distance can be matched according to the thickness of the distance between the two adjacent wires when the metal core material 11 is welded to the interface, so that a process can be omitted.

[0041] Preferably, the number of semicircular parts between two adjacent comb teeth is greater than the number of conductors in the wire 1; specifically, in the process of the die-cutting knife 4 contacting the multiple flattened conductors, the comb-tooth-shaped blade of the die-cutting knife 4 also has an extrusion effect on the multiple conductors in the horizontal direction. If the number of semicircular parts is equal to the number of conductors, it is easy for the conductor at the edge to be unable to be stuck by the semicircular part of the die-cutting knife 4. In this way, the insulating skin 10 of the conductor cannot be die-cut. Therefore, the number of semicircular parts on the blade of the die-cutting knife 4 should be greater than the number of conductors.

[0042] Preferably, a second support rod 51 is provided on the pressing plate 5 for sliding along the pressing direction, and a third elastic member is provided between the second support rod 51 and the pressing plate 5 in the sliding direction, and the pressing plate 5 transmits power of the second support rod 51 based on the third elastic member to press the end of the wire 1.

[0043] Specifically, in the aforementioned embodiment, the movement of each group of pressing plates 5 can be achieved by a separately arranged screw transmission mechanism. The present embodiment also provides a passive movement method, that is, the pressing plate 5 and the corresponding wire rubbing plate 3 can be powered by a transmission rod. During the vertical movement of the wire rubbing plate 3, the transmission rod can drive the corresponding pressing plate 5 to move synchronously vertically. During the process of the wire rubbing plate 3 and the pressing plate 5 moving away from each other in the length direction of the wire 1, the transmission rod does not transmit power, that is, the connection method between the transmission rod and the wire rubbing plate 3 is a sliding arrangement along the length direction of the wire 1, and the transmission rod The connection method with the corresponding pressing plate 5 is also a sliding arrangement along the length direction of the wire 1. When the transmission rod transmits the power of the vertical movement of the wire rubbing plate 3, it drives the second support rod 51 to move, and the second support rod 51 drives the pressing plate 5 to move through the third elastic member. When each group of pressing plates 5 presses the end of the wire 1, the third elastic member has a large elastic force. In the process of the outer insulating skin 10 of the wire 1 gradually separating from the wire 1, under the elastic force of the third elastic member, each group of pressing plates 5 can flatten the cut insulating skin 10 so that the insulating skin 10 can be smoothly separated from the end of the wire 1.

[0044] Furthermore, a slider 31 is provided on the wire rubbing plate 3, and a fourth elastic member is provided between the slider 31 and the wire rubbing plate 3 in the sliding direction, and the wire rubbing roller 30 is provided on the slider 31 at the corresponding position. When the rubbing wire 1 rotates, the sliding of the slider 31 on the corresponding wire rubbing plate 3 in the direction away from the wire 1 is restricted. When the conductor inside the rubbing wire 1 rotates, the sliding of the slider 31 on the corresponding wire rubbing plate 3 in the direction away from the wire 1 is also restricted.

[0045] Specifically, since the metal core material 11 inside the wire is composed of multiple thin guide wires, after the insulating skin 10 is removed, the multiple thin guide wires are scattered, and a separate process is required, that is, the scattered multiple thin guide wires are twisted into strands to facilitate welding in the next process. Therefore, in this embodiment, the wire rolling roller 30 arranged on the wire rolling board 3 is arranged for sliding through the slider 31, and a fourth elastic member is provided between the slider 31 and the wire rolling board 3. In order to ensure that the pressing force applied by the wire rolling roller 30 to the wire 1 or multiple wires remains unchanged when the wire 1 or multiple wires are rotated, the sliding of the slider 31 on the wire rolling board 3 is restricted, that is, if the slider 31 is not hindered by the wire 1, it can continue to slide in the direction away from the wire rolling board 3, otherwise the sliding will be restricted, and in the insulation of multiple wires. During the process of the insulating skin 10 being cut off and grasped and separated, when the wire 1 moves, it will drive the leaked multiple thin guide wires to gradually align with the wire rolling roller 30 up and down, and because the die-cutting knife 4 has combed the multiple wires, the multiple thin guide wires corresponding to the two wires at adjacent positions can basically not affect each other. In this way, after the wire rolling roller 30 is aligned with the multiple thin guide wires, because there is no obstruction from the insulating skin 10, under the elastic force of the fourth elastic member, the upper and lower corresponding wire rolling rollers 30 press the multiple thin guide wires, and at this time each group of wire rolling plates 3 can move in the opposite direction, that is, drive the corresponding group of die-cutting knives 4 to move away from each other in the vertical direction. After the die-cutting knife 4 pushes the cut insulating skin out of the wire, the wire rolling roller 30 is still in contact with the metal core material, and the two upper and lower corresponding wire rolling rollers 30 will rub the multiple thin guide wires gradually into a strand.
