Description

Technical Field

[0001] The present application relates to the technical field of steel core aluminum stranded wire detection experiments, and in particular to a steel core aluminum stranded wire processing device and method. Background Art

[0002] Steel core aluminum stranded wire refers to a reinforced conductor with single or multiple layers of aluminum strands twisted around a galvanized steel core wire. It has a steel "core" inside and aluminum wires twisted around the steel core outside; the steel core mainly serves to increase strength, while the aluminum stranded wire mainly serves to transmit electrical energy; steel core aluminum stranded wire has the characteristics of simple structure, convenient installation and maintenance, low line cost, large transmission capacity, and is convenient for laying across rivers and valleys and other special geographical conditions. It has good electrical conductivity and sufficient mechanical strength, high tensile strength, and can be enlarged in tower distance. It is widely used in overhead power transmission and distribution lines of various voltage levels. Therefore, ensuring the quality of steel core aluminum stranded wire and conducting necessary quality inspections on steel core aluminum stranded wire are of great significance to ensuring the safety of national power transmission. Quality inspections include: (1) diameter inspection of aluminum stranded wire and steel core; (2) inspection of the number of aluminum stranded wires and steel cores in each layer; (3) inspection of the pitch-diameter ratio of each layer of aluminum stranded wire; (4) surface quality inspection of aluminum stranded wire; and (5) winding inspection experiments. Before carrying out the above test items, it is necessary to untwist the wound steel core aluminum stranded wire, split the steel core aluminum stranded wire, cut multiple test samples, and then carry out subsequent testing. The processed steel core aluminum stranded wire is tightly wound and difficult to untwist.

[0003] The Chinese utility model patent with application number 2017211072110 discloses a steel core aluminum stranded wire disassembling and separation machine, which can realize automatic disassembly and separation of steel core aluminum stranded wire through the first wire reel, the second wire reel and the third wire reel, greatly reducing the human participation in the work. However, when using the disassembly and separation machine, the aluminum stranded wire needs to be manually peeled off and fixed to the first wire reel and the second wire reel. This working mode is suitable for the disassembly and separation of single-layer aluminum stranded wire. When disassembling and separating multi-layer steel core aluminum stranded wire, it is necessary to manually peel off the aluminum stranded wire multiple times and fix the aluminum stranded wire to the first wire reel and the second wire reel. The convenience of use needs to be improved. At the same time, in the detection test, the experimenter also needs to cut multiple sections of aluminum stranded wire for detection, which will greatly increase the fixing work of the aluminum stranded wire and reduce the detection efficiency. Summary of the invention

[0004] In view of the problem mentioned in the background technology that aluminum strands need to be manually stripped, the ease of use needs to be improved, and the detection efficiency is low, the present application provides a steel core aluminum stranded wire processing device and method.

DETAILED DESCRIPTION

[0068] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0069] In a first aspect, the present invention provides a steel core aluminum stranded wire processing device, which can be referred to in conjunction with Figure 1 to Figure 3The steel core aluminum stranded wire processing device includes a feeding and feeding mechanism 100, a first clamping mechanism 200, a second clamping mechanism 300, a counting mechanism 400 and a cutting mechanism 500; the device as a whole belongs to a wire processing device, so the steel core aluminum stranded wire can pass through the feeding and feeding mechanism 100, the first clamping mechanism 200, the second clamping mechanism 300, the counting mechanism 400 and the cutting mechanism 500 at the same time; the feeding and feeding mechanism 100 is used to transport the steel core aluminum stranded wire, and its function is to drive the steel core aluminum stranded wire to move forward or backward so that the steel core aluminum stranded wire passes through the first clamping mechanism 200, the second clamping mechanism 300, the counting mechanism 400 or the cutting mechanism 500; the first clamping mechanism 200 is arranged at intervals with the feeding and feeding mechanism 100; the second clamping mechanism 300 is arranged at intervals with the first clamping mechanism 200 and has a rotatable clamping end, wherein the clamping end is used to form a clamping effect on the steel core aluminum stranded wire; the counting mechanism The mechanism 400 is arranged at intervals with the second clamping mechanism 300 and is used to detect the number of untwisted aluminum strands; the truncation mechanism 500 is arranged at intervals with the second clamping mechanism 300, and includes a top-opening cone sleeve 501, a clamping assembly 502 and a wire-management assembly 503. The top-opening cone sleeve 501 is provided with an avoidance hole for the untwisted aluminum strands to pass through. The clamping assembly 502 is arranged adjacent to the top-opening cone sleeve 501 to clamp the top-opened aluminum strands. The wire-management assembly 503 includes a first wire-management semi-ring 5031 and a second wire-management semi-ring 5032. The first wire-management semi-ring 5031 and the second wire-management semi-ring 5032 are respectively connected to the clamping assembly 502 through a displacement drive assembly. The first wire-management semi-ring 5031 and the second wire-management semi-ring 5032 are spliced ​​into a ring driven by the displacement drive assembly to set the untwisted aluminum strands therein and move linearly along the length direction of the aluminum strands to limit the untwisted aluminum strands to an expected maximum opening diameter.

[0070] The untwisting process is as follows: first, the feeding and feeding mechanism 100 drives the steel core aluminum stranded wire forward so that the end of the steel core aluminum stranded wire passes through the first clamping mechanism 200 and is located in the second clamping mechanism 300, so that the first clamping mechanism 200 clamps the steel core aluminum stranded wire, and the clamping end on the second clamping mechanism 300 clamps the end of the steel core aluminum stranded wire, and the clamping end rotates to drive the steel core aluminum stranded wire to twist. Since the rotation directions of the two adjacent layers of aluminum stranded wire of the steel core aluminum stranded wire are opposite, the outermost layer of aluminum stranded wire is untwisted, while the inner layer of aluminum stranded wire is not affected. After the untwisting degree of the aluminum stranded wire reaches the expected level, the clamping end stops rotating and the connection is completed. The clamping end releases the clamping of the steel-core aluminum stranded wire, and the untwisted aluminum stranded wire separates from the inner layer aluminum stranded wire under the elastic force of its own elastic deformation. The second clamping mechanism 300 provides sufficient passing space for the steel-core aluminum stranded wire to prevent the untwisted aluminum stranded wire from interfering with the second clamping mechanism 300. The steel-core aluminum stranded wire is then driven forward by the feeding and feeding mechanism 100, and the number of untwisted aluminum stranded wires is detected and counted by the counting mechanism 400. During the advancement of the steel-core aluminum stranded wire, the untwisted aluminum stranded wire will be located at the small diameter end of the top-opening cone sleeve 501. As the steel-core aluminum stranded wire continues to advance, the top-opening cone sleeve 501 will push the untwisted aluminum stranded wire to the top The wire management component 503 is used to limit the untwisted aluminum strands to a preset maximum opening diameter to prevent individual aluminum strands from being pushed open and transitioning. When the steel-core aluminum strand continues to move forward, the end of the untwisted aluminum strand reaches the clamping component 502, and the clamping component 502 clamps the end of the aluminum strand. The steel-core aluminum strand is driven to retreat through the feeding and feeding mechanism 100, and the untwisted aluminum strand can be straightened. The straightened aluminum strand is evenly distributed in the circumferential direction. At this time, the aluminum strand is cut off. The cutting method can be manual cutting, or a shearing tool that can rotate circumferentially can be set to cut the aluminum strand. For example, the counting mechanism 400 counts the number of aluminum strands and detects the position of each aluminum strand at the same time, and the shearing tool cuts the aluminum strand at different positions on the circumference according to the position of each aluminum strand, and the steel core aluminum strand is driven by the feeding mechanism 100 to retreat until the end of the steel core aluminum strand reaches the second clamping mechanism 300 to untwist the inner layer aluminum strand. The specific process is the same as the above process and will not be repeated here; when the aluminum strands of each layer of a section of steel core aluminum strand are untwisted, the cut-off point is used as the end of the steel core aluminum strand, and the above content is repeated to untwist and cut the next section of the steel core aluminum strand.

[0071] When a shearing tool is used for automatic cutting, the shearing tool and the circumferential driving mechanism may be connected via a linear module so that the shearing tool can approach the aluminum strand in the radial direction.

[0072] Compared with the existing steel core aluminum stranded wire disassembly and separation device, the steel core aluminum stranded wire processing device provided by the present application does not need to manually peel off the aluminum strands of the steel core aluminum stranded wire. The present application utilizes the characteristic that the adjacent layers of aluminum strands in the multi-layer steel core aluminum stranded wire have opposite rotation directions to directly twist the steel core aluminum stranded wire to achieve the untwisting of the aluminum strands. After the untwisted aluminum strands are clamped by the clamping assembly 502, they can be straightened in conjunction with the feeding and feeding mechanism 100, so that the aluminum strands can be conveniently cut. The cut steel core aluminum stranded wire can return to the second clamping mechanism 300 under the drive of the feeding and feeding mechanism 100 to untwist another layer of aluminum stranded wire / untwist another segment of aluminum stranded wire. During the whole process, the staff does not need to repeatedly peel off the aluminum stranded wire, and does not need to fix the aluminum stranded wire, which is beneficial to improving the overall efficiency of the detection test.

[0073] In some optional embodiments, see Figure 4 The feeding and feeding mechanism 100 includes a flexible wheel group 101 and a guide wheel group 102; the flexible wheel group 101 has two flexible wheels, which are arranged adjacent to each other, and a wire pressing gap is formed between the two flexible wheels. The steel-core aluminum stranded wire passes through the wire pressing gap between the two flexible wheels. The two flexible wheels can form pressure on the steel-core aluminum stranded wire. When one of the flexible wheels is driven to rotate, the steel-core aluminum stranded wire can be driven forward or backward. That is to say, in the flexible wheel group 101, at least one flexible wheel is configured with a motor (not shown in the figure); the guide wheel group 102 has two guide wheels, which are arranged adjacent to each other, and a guide gap is formed between the two guide wheels. After the steel-core aluminum stranded wire passes through the guide gap, the two guide wheels can limit the steel-core aluminum stranded wire to ensure the stability of the posture of the steel-core aluminum stranded wire and avoid bending of the steel-core aluminum stranded wire. That is to say, the guide wheel group 102 can straighten the steel-core aluminum stranded wire. In actual implementation, the guide wheel is a wheel body structure with an arc groove on the outer side of the wheel.

[0074] In some optional embodiments, the flexible wheel set 101 is provided in plurality, and the plurality of flexible wheel sets 101 are arranged linearly. The plurality of flexible wheel sets 101 can play a better driving role on the steel-core aluminum stranded wire. For example, when the steel-core aluminum stranded wire slips with one of the flexible wheel sets 101, the steel-core aluminum stranded wire can still be driven by other flexible wheel sets 101. In actual implementation, in order to ensure the rotation synchronization of the flexible wheels in the plurality of flexible wheel sets 101, each flexible wheel set 101 shares a motor. For example, bevel gears are arranged on the flexible wheels in each flexible wheel set 101, and a driving shaft is connected to the motor output shaft. The driving shaft is provided with a plurality of bevel gears that cooperate with the flexible wheel transmission, so that a plurality of flexible wheels can be driven to rotate synchronously by one motor.

[0075] In some optional embodiments, the guide wheel group 102 is provided in plurality, and the plurality of guide wheel groups 102 are arranged linearly with the flexible wheel group 101. The plurality of guide wheel groups 102 can achieve a better guiding and straightening effect, and the steel core aluminum stranded wire has more time to release stress when passing through the plurality of guide wheel groups 102, thereby ensuring that the steel core aluminum stranded wire has good straightness.

[0076] In some optional embodiments, a plurality of guide wheel groups 102 may also be provided between the second clamping mechanism 300 and the cutting mechanism 500, and these guide wheel groups 102 are used to guide and support the untwisted steel-core aluminum stranded wire; since the diameter of the steel-core aluminum stranded wire will become smaller after being untwisted layer by layer, the guide wheels in these guide wheel groups 102 are all provided with elastic parts to make the two guide wheel groups 102 close to each other, thereby ensuring that the two guide wheels can contact the steel-core aluminum stranded wires with different diameters.

[0077] In some optional embodiments, see Figure 5The first clamping mechanism 200 includes a first mounting disc 201, a clamping block 202, a ratchet ring 203 and a clamping motor (not shown in the figure); the first mounting disc 201 can be mounted on the ground or other artificially constructed support platforms through a bracket, and the first mounting disc 201 is coaxially provided with a first threading hole, and the first threading hole is used for the steel core aluminum stranded wire to pass through, and the first mounting disc 201 is radially provided with three sliding holes connected with the first threading hole, which means that the axis of each sliding hole coincides with the radial direction of the first mounting disc 201, and the three sliding holes are evenly distributed along the circumference of the first mounting disc 201, and the outer wall of the first mounting disc 201 is coaxially provided with an annular groove, and the annular groove is connected with the first threading hole through the sliding hole, which is equivalent to opening a sliding hole from the bottom of the annular groove along the radial direction of the first mounting disc 201 until the sliding hole is connected with the first threading hole; three clamping blocks 202 are slidably arranged in the sliding holes, and the clamping blocks 202 can The clamping block 202 is configured as a circular rod, and an elastic member is arranged between each clamping block 202 and the hole wall of the corresponding sliding hole so that the clamping block 202 has a sliding tendency to slide away from the first threading hole. The elastic member can be configured as a spiral spring to ensure that the direction of the elastic force on the clamping block 202 is stable. Part of the structure of the clamping block 202 is located in the annular groove, which means that under the elastic force of the elastic member, the end of the clamping block 202 is maintained at a position higher than the bottom of the annular groove; the ratchet ring 203 is coaxially arranged in the annular groove and slidably connected to the groove wall of the annular groove so that the ratchet ring 203 can rotate freely in the annular groove. For example, sliding rods are respectively arranged on the two side walls of the ratchet ring 203, and an annular sliding groove adapted to the sliding rod is opened on the groove wall of the annular groove. The ratchet in the ratchet ring 203 contacts the clamping block 202, and the outer side of the ratchet ring 203 is configured with gear teeth; the clamping motor is connected to the ratchet ring 203 through gear transmission to drive the ratchet ring 203 to rotate. Start the clamping motor, and the clamping motor drives the ratchet ring 203 to rotate. Due to the ratchet structural characteristics on the ratchet ring 203, the ratchet and the end of the clamp block 202 slide, and the ratchet will continue to press the clamp block 202. Driven by the ratchet ring 203, the three clamp blocks 202 synchronously enter the first threading hole, thereby achieving the centering clamping of the steel-core aluminum stranded wire, ensuring the centering of the steel-core aluminum stranded wire, and avoiding eccentric torsion when the clamping end drives the steel-core aluminum stranded wire to rotate; the ratchet ring 203 is driven by the clamping motor to rotate in the opposite direction, and each clamp block 202 withdraws from the first threading hole under the elastic force of the elastic member, thereby allowing the first clamping mechanism 200 to release the clamping effect on the steel-core aluminum stranded wire.

[0078] In some optional embodiments, see Figure 6The second clamping mechanism 300 includes a second mounting disc 301, a three-jaw chuck 302 and a rotating motor (not shown in the figure); the second clamping mechanism 300 is coaxially provided with a second threading hole, and the second threading hole is used for the untwisted steel-core aluminum stranded wire to pass through. The untwisted aluminum stranded wire will open to a certain extent and requires a larger passing space. Therefore, the diameter of the second threading hole is much larger than the diameter of the first threading hole. For example, the diameter of the second threading hole is set to 5 times, 6 times, 7 times, 8 times, 9 times or 10 times the diameter of the second threading hole, which can be determined according to the untwisting length; the three-jaw chuck 302 is rotatably connected to the second mounting disc 301, which means that the three-jaw chuck 302 can rotate freely on the second mounting disc 301; the rotating motor is transmission-connected to the three-jaw chuck 302 to drive the three-jaw chuck 302 to rotate on the second mounting disc 301. The three-jaw chuck 302 as the clamping end of the second clamping mechanism 300 can realize the centering clamping of the steel core aluminum stranded wire, thereby ensuring the coaxiality of the two clamped parts on the steel core aluminum stranded wire and avoiding eccentric torsion of the steel core aluminum stranded wire when the three-jaw chuck 302 rotates.

[0079] In some optional embodiments, the first clamping mechanism 200 is configured with a sliding track 600 so as to move closer to or away from the second clamping mechanism 300 driven by the sliding track 600 . After the feeding-in and feeding-out mechanism 100 drives the steel-core aluminum stranded wire to pass through the first clamping mechanism 200, due to the spacing between the first clamping mechanism 200 and the second clamping mechanism 300, the steel-core aluminum stranded wire may be slightly bent during the continuous forward movement, resulting in the end of the steel-core aluminum stranded wire not being able to be located in the clamping area of ​​the three-jaw chuck 302. After the sliding track 600 is set, the end of the steel-core aluminum stranded wire only needs to pass through the first clamping mechanism 200 for a short distance, and the steel-core aluminum stranded wire is clamped by the first clamping mechanism 200 and driven to move by the sliding track 600, and finally the end of the steel-core aluminum stranded wire is brought into the second clamping mechanism 300. Since the spacing between the end of the steel-core aluminum stranded wire and the first clamping mechanism 200 is short, the coaxiality of this section of the steel-core aluminum stranded wire is high, and the steel-core aluminum stranded wire can be successfully clamped by the three-jaw chuck 302 in the middle position of the second clamping mechanism 300.

[0080] In some optional embodiments, please refer to Figure 2 , Figure 3 , Figure 7 and Figure 8, the clamping assembly 502 includes a clamping disc 5021, a clamping block 5022 and a clamping power source 5023; the clamping disc 5021 can also be set as a disc, and the clamping disc 5021 can be installed on the ground or other supporting platforms through a bracket. The clamping disc 5021 is coaxially provided with a third threading hole, and the function of the third threading hole is to avoid the untwisted steel-core aluminum stranded wire. The clamping disc 5021 is also provided with three clamping grooves, which are arc-shaped grooves, and the center of curvature corresponding to the clamping groove is located on the axis of the clamping disc 5021, and the three clamping grooves are evenly distributed along the circumference of the third threading hole; the clamping block 5022 is located in the clamping groove and can slide in the clamping groove along the radial direction of the third threading hole. The shape of the clamping block 5022 is similar to that of the clamping groove. One side of 5022 close to the third threading hole is set as an arcuate surface, which is adapted to the side wall shape of the clamping groove close to the third threading hole; the clamping power source 5023 is connected to the clamping block 5022 to drive the clamping block 5022 to slide in the clamping groove, and the clamping power source 5023 can be set to a cylinder, and the sliding direction of the clamping block 5022 is along the radial direction of the third threading hole, so that the arcuate surface on the clamping block 5022 is away from or close to the groove wall of the clamping groove close to the third threading hole; wherein, the large diameter end of the top opening cone sleeve 501 is connected to the clamping disk 5021, and the edge of the large diameter end of the top opening cone sleeve 501 coincides with the inner groove edge of the three clamping grooves, where the inner groove edge refers to the groove edge on the clamping groove close to the third threading hole, and the avoidance hole is connected to the third threading hole. After the outer layer of aluminum strands is untwisted, it will open to a certain extent, which means that the end of the aluminum strand will leave the inner layer of untwisted steel-core aluminum strands. However, for a single aluminum strand, due to the small elastic modulus of the aluminum strand, the aluminum strand will not be in a straight line after the second clamping mechanism 300 releases the clamp, and the end position of each aluminum strand is not fixed. At this time, the end of the aluminum strand cannot be clamped directly; the untwisted steel-core aluminum strand is driven by the feeding mechanism 100 to approach the cutting mechanism 50 0. The untwisted steel-core aluminum stranded wire enters the inner hole of the top-open cone sleeve 501. During the forward movement of the steel-core aluminum stranded wire, each aluminum stranded wire will gradually contact the side of the top-open cone sleeve 501. When the steel-core aluminum stranded wire continues to move forward, the top-open cone sleeve 501 is equivalent to pushing the aluminum stranded wire open, and the ends of each aluminum stranded wire move away from each other. Under the guidance of the side of the top-open cone sleeve 501, the ends of each aluminum stranded wire enter the clamping groove, and the clamping power source 5023 drives the clamping block 5022 to move to clamp the ends of the aluminum stranded wire. In the process of pushing open the aluminum strands by the cone sleeve 501, there are some individual aluminum strands whose angles are too large, which will cause some of the aluminum strands to be unable to enter the clamping groove. At this time, it is necessary to form a limiting ring structure by combining the first wire management half ring 5031 and the second wire management half ring 5032 in the wire management component 503 to limit all the aluminum strands, ensuring that the individual aluminum strands with too large angles are at the desired maximum opening diameter, and the aluminum strands can enter the clamping groove at the maximum opening diameter.

[0081] Of course, the untwisted aluminum strands are in an open state, and each aluminum strand can be separated from each other, and the number of aluminum strands can be detected at this time. The counting mechanism 400 may include a slip ring, a sliding mechanism and a counting sensor. The slip ring is located between the cut-off mechanism 500 and the second clamping mechanism 300. The slip ring can be installed on the ground or other supporting platforms through a bracket. The slip ring has an inner diameter sufficient for the untwisted steel-core aluminum strand to pass through. The counting sensor is connected to the inner side of the slip ring through the sliding mechanism. The sliding mechanism may specifically include a slip ring and a sliding motor. The slip ring is coaxially sleeved on the inner side of the slip ring. The slip ring is slidably connected to the slip ring. For example, a sliding rod is arranged on the slip ring, and an annular sliding groove adapted to the sliding rod is arranged on the inner side wall of the slip ring. The counting sensor is connected to the inner wall of the slip ring. A transmission tooth is constructed on the side wall of the slip ring. The slip ring is connected to the sliding motor through the transmission tooth. Therefore, after the sliding motor is driven to rotate, the counting sensor can make a circular motion, and the counting sensor can count the aluminum strands.

[0082] In some optional embodiments, see Figure 2 , Figure 3 and Figure 8The displacement drive assembly includes a first linear module 5033 and a second linear module 5034; the first linear module 5033 is connected to the clamping disk 5021, and its moving end has a moving direction along the axial direction of the avoidance hole; the second linear module 5034 is connected to the moving end of the first linear module 5033, and the moving end of the second linear module 5034 is connected to the first wire-manipulating semi-ring 5031 / the second wire-manipulating semi-ring 5032 and has a moving direction along the radial direction of the avoidance hole; wherein the first wire-manipulating semi-ring 5031 and the second wire-manipulating semi-ring 5032 are evenly distributed with a plurality of wire-manipulating teeth along the circumferential direction on the inner side, and the inner side segments of the plurality of wire-manipulating teeth are located in a circle The circumferential diameter is larger than the small diameter end of the top open cone sleeve 501 and smaller than the large diameter end of the top open cone sleeve 501, that is, after the first wire management semi-ring 5031 and the second wire management semi-ring 5032 are combined into a circular ring, the small diameter end of the top open cone sleeve 501 can be sleeved on the side of the top open cone sleeve 501, and the spacing between two adjacent wire management teeth is larger than the diameter of a single aluminum stranded wire and smaller than twice the diameter of a single aluminum stranded wire, that is, two adjacent wire management teeth can only accommodate one aluminum stranded wire, which is beneficial to the separation of the aluminum stranded wires. In actual implementation, the end of the wire management tooth is constructed as a conical surface, which is beneficial to make the two adjacent aluminum stranded wires located in the gap between two adjacent teeth. The first wire-managing half ring 5031 and the second wire-managing half ring 5032 move along the length direction of the steel-core aluminum stranded wire under the drive of the respectively connected first linear modules 5033 until the first wire-managing half ring 5031 and the second wire-managing half ring 5032 correspond to the position where the outer layer of the steel-core aluminum stranded wire has not been untwisted in the length direction of the steel-core aluminum stranded wire, and the first wire-managing half ring 5031 and the second wire-managing half ring 5032 approach each other and combine into a circular ring under the drive of the respectively connected second linear modules 5034. At this time, the steel-core aluminum stranded wire is sleeved in the circular ring, and the circular ring approaches the top-opening cone sleeve 501 under the drive of the first linear module 5033. During the approaching process, the circular ring will interfere with the untwisted aluminum stranded wire, forcing the aluminum stranded wire to bend so that the end of the aluminum stranded wire approaches the top-opening cone sleeve 501, thereby allowing the end of the aluminum stranded wire to enter the clamping groove.

[0083] In some optional embodiments, the three clamping grooves are not continuous, and there is a solid structure between two adjacent clamping grooves. If the end of the aluminum stranded wire corresponds to the position of the solid structure, the aluminum stranded wire cannot be successfully clamped. Therefore, the first wire-management semi-ring 5031 and the second wire-management semi-ring 5032 are also provided with separation teeth, the width of the separation teeth in the circumferential direction is equal to the width of the aforementioned solid structure, and the end of the separation teeth is a conical structure. Of course, the separation teeth may guide the two aluminum stranded wires to the gap between the adjacent wire-management teeth on one side, but this does not affect the clamping function of the clamping assembly 502 on the aluminum stranded wire.

[0084] In some optional embodiments, the cut-off mechanism 500 also cooperates with the slider rail, and the cut-off mechanism 500 is driven by the hydraulic cylinder 700 to slide on the slider rail, thereby moving away from the second clamping mechanism 300 to achieve straightening of the aluminum stranded wire. This structure is suitable for occasions where the aluminum stranded wire has a large diameter and relatively large rigidity. During the straightening process, the steel core aluminum stranded wire is clamped by the second clamping mechanism 300, and the end of the aluminum stranded wire is clamped by the clamping assembly 502. The hydraulic cylinder 700 drives the cut-off mechanism 500 away from the second clamping mechanism 300 to achieve the straightening operation of the aluminum stranded wire.

[0085] The straightened and cut aluminum strands are arranged evenly. If there are a large number of single-layer aluminum strands, since the aluminum strands at the cut-off position are in an open state, when the steel-core aluminum strands are retracted and clamped by the second clamping mechanism 300, multiple aluminum strands may overlap, which will be detrimental to the untwisting of the layer of aluminum strands. Therefore, based on the three-jaw chuck 302, the Fig. 9 and Fig.10 The guide piece 3022 can be connected to the claw 3021 of the three-jaw chuck 302. The overall shape of the guide piece 3022 is an arc-shaped plate structure. The guide pieces 3022 on the three claws 3021 can be spliced ​​into a circular disc structure. The radial inner side of the guide piece 3022 is chamfered so that after the three guide pieces 3022 are combined, a conical guide hole is formed in the middle. An elastic piece is connected between the guide piece 3022 and the claw 3021 so that the guide piece 3022 has a tendency to move toward the axis of the three-jaw chuck 302. In other words, when the three guide pieces 3022 contact each other, the claw 302 1 can also move toward the axis without being limited by the guide member 3022. A limited guide groove 30221 is provided on the chamfered surface. When the guide members 3022 are combined to form a guide hole in the middle, the two ends of the limited guide groove 30221 are respectively located at the large diameter end and the small diameter end of the guide hole. The plurality of limited guide grooves 30221 are evenly distributed around the circumference, and the angular positions of the two ends of each limited guide groove 30221 in the circumferential direction do not overlap, which means that the angles traveled from a point in the circumferential direction to the two ends of the limited guide groove 30221 are not equal, and the depth of the small diameter end of the limited guide groove 30221 is less than the depth of the large diameter end. When the cut-off position on the steel-core aluminum stranded wire enters the guide hole, the aluminum stranded wire can be located in the limiting guide groove 30221. At this time, the steel-core aluminum stranded wire can be clamped by the first clamping mechanism 200, and the clamping end is rotated so that the guide member 3022 forms a winding effect on the aluminum stranded wire, thereby reducing the opening effect of the aluminum stranded wire end. While the clamping end rotates, the sliding guide rail drives the first clamping mechanism 200 to move. Since the depths at both ends of the limiting guide groove 30221 are different, each limiting guide groove 30221 can also form a gathering effect on the aluminum stranded wire, thereby facilitating the second clamping mechanism 300 to clamp the steel-core aluminum stranded wire and avoid overlapping of certain aluminum stranded wires when clamped.

[0086] It should be noted that the maximum distance between the first clamping mechanism 200 and the second clamping mechanism 300 is usually no more than 1m. In actual detection tests, the sampling length of the aluminum stranded wire is generally 1m. Therefore, the maximum spacing between the first clamping mechanism 200 and the second clamping mechanism 300 is less than 1m, thereby ensuring the untwisting effect of the aluminum stranded wire, ensuring that the ends of the aluminum stranded wire can be lifted up and away from the inner layer of aluminum stranded wire after being untwisted, and during the untwisting process, the middle section of the untwisted aluminum stranded wire will not be bent again. In other words, the steel core aluminum stranded wire processing device provided in the present application is particularly suitable for aluminum stranded wire detection occasions.

[0087] In a second aspect, the present application provides a steel core aluminum stranded wire processing method, which is implemented based on the steel core aluminum stranded wire processing device of the first aspect, and includes the following contents:

[0088] S1. The feeding-in and feeding-out mechanism 100 is operated to drive the steel core aluminum stranded wire to move forward. Driven by the feeding-in and feeding-out mechanism 100, the steel core aluminum stranded wire can enter the first clamping mechanism 200 and pass through the first clamping mechanism 200.

[0089] S2. After the end of the steel core aluminum stranded wire passes through the expected length of the first clamping mechanism 200, the first clamping mechanism 200 clamps the steel core aluminum stranded wire and drives the first clamping mechanism 200 to move forward through the sliding guide rail. During the forward movement of the first clamping mechanism 200, the feeding and feeding mechanism 100 continues to drive the steel core aluminum stranded wire, which means that the steel core aluminum stranded wire and the first clamping mechanism 200 move forward synchronously, and the forward speeds of the two are the same, so as to avoid slipping of the steel core aluminum stranded wire and the flexible wheel group 101.

[0090] S3. After the end of the steel core aluminum stranded wire reaches the second clamping mechanism 300, the second clamping mechanism 300 clamps the end of the steel core aluminum stranded wire, releases the clamping of the steel core aluminum stranded wire by the first clamping mechanism 200, and drives the first clamping mechanism 200 to move backward through the sliding guide rail, that is, when the second clamping mechanism 300 clamps the end of the steel core aluminum stranded wire, the sliding guide rail drives the first clamping mechanism 200 to return to the initial position. During this process, the feeding and discharging mechanism 100 stops working.

[0091] S4. The first clamping mechanism 200 clamps the steel core aluminum stranded wire, and drives the clamping end of the second clamping mechanism 300 to rotate to achieve untwisting of the steel core aluminum stranded wire.

[0092] S5. Release the clamping of the second clamping mechanism 300 on the end of the steel core aluminum stranded wire, so that the feeding and feeding mechanism 100 works to drive the steel core aluminum stranded wire to move forward. During this process, the first clamping mechanism 200 can move forward synchronously with the steel core aluminum stranded wire under the drive of the sliding guide rail, and the first clamping mechanism 200 can also release its clamping of the steel core aluminum stranded wire.

[0093] S6. Detect the number of untwisted aluminum strands through the counting mechanism 400, that is, the counting sensor rotates one circle to detect and count the number of aluminum strands. During this process, the feeding mechanism 100 can be stopped, so that the rotation speed of the counting sensor can be relatively slow and the detection result is more accurate.

[0094] S7. The untwisted aluminum stranded wire is pushed open by the opening cone sleeve 501, and the opened aluminum stranded wire is limited to the expected maximum opening diameter by the wire management component 503. During this process, there is no need to stop the feeding and feeding mechanism 100, and the movement speed of the wire management component 503 can be set to be greater than the forward speed of the steel core aluminum stranded wire.

[0095] S8. The feeding-in and feeding-out mechanism 100 is operated to drive the steel-core aluminum stranded wire to move forward, and the untwisted aluminum stranded wire is clamped by the clamping assembly 502.

[0096] S9. The feeding and feeding mechanism 100 is operated to drive the steel-core aluminum stranded wire to move backward so that the aluminum stranded wire is straightened. This method is suitable for occasions where the aluminum stranded wire has a relatively low stiffness. For occasions where the aluminum stranded wire has a relatively high stiffness, the hydraulic cylinder 700 can be used to drive the cutting mechanism 500 to slide on the sliding guide rail to achieve straightening of the aluminum stranded wire. At this time, the steel-core aluminum stranded wire needs to be clamped by the first clamping mechanism 200.

[0097] S10, cut off the aluminum stranded wire;

[0098] S11. The feeding-in and feeding-out mechanism 100 is operated to drive the steel-core aluminum stranded wire to move backward until the end of the steel-core aluminum stranded wire is located at the second clamping mechanism 300, and the end of the steel-core aluminum stranded wire is clamped by the second clamping mechanism 300. During this process, when the end of the aluminum stranded wire is close to the clamping claw 3021, the clamping claw 3021 is driven to gather so that the guide member 3022 on the clamping claw 3021 forms a circular ring sheet. When the steel-core aluminum stranded wire retreats, the slightly opened aluminum stranded wire on it will enter the limiting guide groove 30221, and the three-jaw chuck 302 is driven to rotate so that the guide member 3022 winds the aluminum stranded wire. During the rotation of the three-jaw chuck 302, the feeding-in and feeding-out mechanism 100 continues to work, and the aluminum stranded wire can be wound and gathered on the inner layer of aluminum stranded wire, which will be beneficial for the clamping claw 3021 to clamp the steel-core aluminum stranded wire and avoid overlapping of multiple aluminum stranded wires after being clamped.

[0099] S12, repeating steps S4 to S11 until the last layer of aluminum stranded wires of the steel core aluminum stranded wire is cut off.

[0100] S13, the feeding-in and feeding-out mechanism 100 is operated to drive the steel-core aluminum stranded wire to move backward until the untwisted aluminum stranded wire end is located at the second clamping mechanism 300.

[0101] S14, repeating steps S12 to S13 until the aluminum strands of the steel-core aluminum stranded wire with the expected length are cut.

[0102] From the above content, it can be seen that during the processing of steel core aluminum stranded wire, there is no need to manually strip the aluminum stranded wire or fix the end of the aluminum stranded wire manually. The labor intensity of the experimenters is greatly reduced, which is conducive to the experimenters to take multiple and multi-segment samples of the aluminum stranded wire, and is conducive to improving the overall efficiency of the detection experiment.
