Description

Technical Field

[0001] The present application relates to the technical field of wire crimping technology, and in particular to a wire crimping device and a crimping method. Background Art

[0002] Overhead transmission lines are a crucial component of power grid systems, and their construction quality is directly linked to their safe operation. Failures can cause significant losses to the grid. Wire crimping is a crucial step in the tension stringing process of transmission line construction, and its quality is crucial to its safe operation.

[0003] In the related art, in order to improve the efficiency of crimping wires, wire crimping equipment is often used. The wire crimping equipment includes a crimping platform, a crimping mechanism and a translation mechanism; its working principle is roughly as follows: first, the stranded wire is passed through the aluminum tube, and then the stranded wire passed through the aluminum tube is stripped, and the stripped stranded wire is inserted into the mounting hole of the steel anchor, and the translation mechanism is started, and the translation mechanism drives the crimping mechanism to move, and the crimping mechanism moves to the crimping position of the stranded wire and the steel anchor, and the crimping mechanism crimps the stranded wire and the steel anchor to fix, and then the translation mechanism is started again, and the translation mechanism drives the crimping mechanism to move, and the crimping mechanism moves to the crimping position of the stranded wire and the aluminum tube, and the crimping mechanism crimps the stranded wire and the aluminum tube, thereby realizing the processing of the wire.

[0004] The inventor believes that the above technology has the following defects: when the steel anchor and the stranded wire are crimped by the crimping mechanism (or when the aluminum tube and the stranded wire are crimped), the machine program failure may occur during the crimping process, and the crimping mechanism may skip steps or be manually paused for adjustment. When the crimping is performed again later, there is a certain difference in the position of the crimping mechanism and the crimping mechanism before the failure, which may cause the wire to be crimped loosely, thereby affecting the crimping quality of the wire. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present application provides a wire crimping device and a crimping method.

[0006] In a first aspect, the present application provides a wire crimping device, which adopts the following technical solution:

[0008] By adopting the above technical solution, the clamping mechanism is adjusted, the clamping mechanism fixes one end of the steel anchor, the stranded wire is passed through the aluminum tube, and one end of the stranded wire is extended into the mounting hole at the unfixed end of the steel anchor, and the crimping space of the crimping mechanism is adjusted to be at the same horizontal line with the steel anchor and the stranded wire, and the driving component is started, and the driving component drives the translation plate to move, and the translation plate moves on the crimping platform, and the movement of the translation plate drives the crimping mechanism to move, and the crimping mechanism moves to the crimping position of the stranded wire and the steel anchor, and the crimping oil cylinder is turned on, and the crimping oil cylinder drives the lower pressure block to approach the upper pressure block, and the lower pressure block approaches the upper pressure block to realize the crimping of the steel anchor and the stranded wire; the driving component is started again, and the driving component drives the translation plate to move, and the translation plate moves on the crimping platform. The crimping platform moves, and the movement of the translation plate drives the crimping mechanism to move. The crimping mechanism moves to the crimping position of the stranded wire and the aluminum tube, and the crimping cylinder is turned on. The crimping cylinder drives the lower pressure block to approach the upper pressure block, and the lower pressure block to approach the upper pressure block to achieve crimping between the aluminum tube and the stranded wire. If during the crimping process, the set infrared ranging sensor detects that the machine may have a tendency to malfunction and skip steps (the distance of each movement of the translation plate is inconsistent), the infrared ranging sensor sends a signal to the limit mechanism, and the limit mechanism limits and fixes the translation plate to ensure that the movement distance of the translation plate is within the specification, thereby making the crimping distance of the crimping mechanism within the specification, which helps to improve the crimping quality of the wire.

[0009] Optionally, the limit mechanism includes a limit slide, a sliding block, a clamping block, a fixing piece and a power piece; the limit slide is arranged on the supporting plate and is located between the translation plate and the supporting plate, wherein the axial direction of the limit slide is the same as the movement direction of the translation plate; the sliding block is slidably connected to the limit slide; the fixing piece is used to fix the sliding block to the limit slide; the clamping block is hinged on the side of the sliding block away from the limit slide, and the side of the translation plate close to the supporting plate is provided with a limit groove corresponding to the clamping block; the power piece is arranged on the sliding block, and the power piece is used to drive the clamping block to extend into the limit groove, so that the clamping block limits the movement of the translation plate.

[0010] By adopting the above technical solution, when the translation plate needs to be limited, the infrared ranging sensor sends a signal to the power part, the power part moves, and the power part drives the clamping block to extend into the limiting groove to achieve the limitation of the translation plate; when processing different wires (different wires have different crimping lengths), the sliding block is moved, and the sliding block moves on the limiting slide bar. When the sliding block moves to the appropriate distance, the fixing part is adjusted, and the fixing part fixes the sliding block and the limiting slide bar. In this way, by changing the distance between adjacent limiting mechanisms, the crimping mechanism can be limited and fixed at a fixed interval, thereby making it possible to crimp different wires. At the same time, it also helps to prevent the crimping mechanism from skipping steps, thereby improving the crimping quality of the wires.

[0011] Optionally, the driving assembly includes a driving rack, a driving gear and a driving motor; the driving rack is arranged on the supporting plate, located between the translation plate and the supporting plate, and the length direction of the driving rack is the same as the axial direction of the limiting slide rod; the driving gear is rotatably connected to the translation plate, and the driving gear is engaged with the driving gear; the driving motor is used to drive the driving gear to rotate.

[0012] By adopting the above technical solution, the driving motor is turned on, the driving motor drives the driving gear to rotate, the driving gear rotates on the driving rack, and the rotation of the driving gear drives the translation plate to move, thereby achieving the purpose of driving the translation plate to move on the supporting plate, so that the purpose of translation of the crimping mechanism on the crimping platform can be achieved.

[0014] By adopting the above technical solution, the lifting motor is turned on, the lifting motor drives the lifting screw to rotate, the rotation of the lifting screw drives the load-bearing plate to move, the load-bearing plate moves on the lifting slide rod, the lifting movement of the load-bearing plate drives the lifting movement of the translation plate, and the lifting movement of the translation plate drives the lifting movement of the crimping mechanism, which helps to adjust the stranded wire and the steel anchor to the same horizontal line, ensure the concentricity of the stranded wire and the steel anchor, and thus improve the crimping quality of the wire.

[0015] Optionally, the clamping mechanism includes a clamping screw, a clamping slide, a fixed block and multiple clamping blocks; the fixed block is connected to the crimping platform; the clamping screw is passed through the fixed block and is rotatably connected to the fixed block, wherein the clamping screw has a positive thread section and a negative thread section, part of the clamping blocks are arranged on the positive thread section, part of the clamping blocks are arranged on the negative thread section, and the relatively arranged clamping blocks form a clamping space; the clamping slide is arranged on the fixed block, the axial direction of the clamping slide is the same as the axial direction of the clamping screw, and the clamping block is slidably connected to the clamping slide.

[0016] By adopting the above technical solution, when clamping and fixing the stranded wire or steel anchor, the stranded wire or steel anchor is placed in the clamping space, and the clamping screw is rotated. The clamping screw drives the relatively arranged clamping blocks to approach each other. When the clamping blocks come into contact with the stranded wire or steel anchor, the stranded wire or steel anchor is clamped and fixed.

[0017] Optionally, the clamping mechanism also includes a limit member; the limit member includes a limit block, a tightening rod and a rotating rod; the limit block is arranged on the side of the fixed block away from the clamping block, and the limit block has a clamping groove, part of the clamping screw is located in the clamping groove, and the space of the clamping groove is variable; the tightening rod passes through the clamping groove and is fixedly connected to the limit block; the rotating rod is rotatably connected to the end of the tightening rod, and the rotating rod moves to drive the tightening rod to move, so as to realize the change of the clamping groove space.

[0018] By adopting the above technical solution, after the twisted wire or steel anchor is clamped and fixed, the rotating rod is adjusted, and the rotating rod drives the tightening rod to move. The movement of the tightening rod causes the space of the clamping groove to continue to shrink, and the side wall of the clamping groove is pressed against the clamping screw, thereby achieving the purpose of locking and limiting the clamping screw, effectively preventing the phenomenon that the clamping screw may be accidentally touched during the crimping process of the wire, resulting in the failure of clamping the twisted wire or steel anchor, affecting the crimping operation of the wire, and improving the working stability of the wire crimping equipment.

[0019] Optionally, the wire crimping device also includes a knocking mechanism; the knocking mechanism includes a semi-arc disk, a knocking rod, a clamping rod and a power assembly; the semi-arc disk is rotatably connected to the crimping shell, and the rotation axis of the semi-arc disk and the crimping shell is perpendicular to the crimping direction of the crimping mechanism; the knocking rod is connected to the upper part of the semi-arc disk, so that when the semi-arc disk is in the first state, the upper pressure block and the wire are separated under the action of the knocking rod; the clamping rod is connected to the lower part of the semi-arc disk, so that when the semi-arc disk is in the second state, the lower pressure block and the wire are separated under the action of the clamping rod; the power assembly is connected to the semi-arc disk, and is used to drive the semi-arc disk to move, so that the semi-arc disk is in the first state or the second state.

[0020] By adopting the above technical solution, when the twisted wire and the steel anchor are crimped, the power component is turned on, and the power component drives the semi-arc disk to move. In the first state, the semi-arc disk drives the knocking rod to move, and the knocking rod approaches the steel anchor, and the knocking rod knocks the steel anchor. Under the continuous action of the semi-arc disk, the knocking rod continuously knocks the steel anchor to achieve the purpose of separating the upper pressure block from the steel anchor. In the second state, the semi-arc disk moves, and the semi-arc disk drives the tightening rod to move. The tightening rod moves to the bottom of the steel anchor, and the crimping cylinder is turned on. The crimping cylinder drives the lower pressure block away from the upper pressure block. The movement of the lower pressure block drives the steel anchor to move. The steel anchor contacts the tightening rod, and under the action of the tightening rod, the lower pressure block and the steel anchor are separated. Similarly, when the twisted wire and the aluminum tube are crimped, the power assembly is turned on, and the power assembly drives the semi-arc disk to move. In the first state, the semi-arc disk drives the knocking rod to move, and the knocking rod approaches the aluminum tube, and the knocking rod knocks the aluminum tube. Under the continuous action of the semi-arc disk, the knocking rod continuously knocks the steel anchor to achieve the purpose of separating the upper pressure block from the aluminum tube. In the first state, the semi-arc disk moves, and the semi-arc disk drives the clamping rod to move. The clamping rod moves to the bottom of the aluminum tube, and the crimping cylinder is turned on. The crimping cylinder drives the lower pressure block away from the upper pressure block. The movement of the lower pressure block drives the aluminum tube to move. The aluminum tube contacts the clamping rod, and the separation between the lower pressure block and the aluminum tube is achieved under the action of the clamping rod. In this way, the purpose of automatic demoulding can be achieved, which helps to improve the efficiency of crimping the wires and facilitates the movement of the crimping mechanism to the next crimping position.

[0021] Optionally, the power assembly includes a power motor, a power gear, a semi-arc rack and at least two blocking blocks; the semi-arc rack is slidably connected to the semi-arc disk; the blocking block is arranged on the semi-arc disk to form a blocking space for the semi-arc rack; the power gear is rotatably connected to the crimping shell, and the power gear is engaged with the semi-arc rack; the power motor is used to drive the power gear to rotate.

[0022] By adopting the above technical solution, the power motor is turned on, the power motor drives the power gear to rotate, the rotation of the power gear drives the power rack to move, the power rack slides on the semi-arc disk, and the power rack contacts and collides with the blocking block, thereby achieving the purpose of driving the semi-arc disk to move.

[0023] Optionally, at least two knocking mechanisms are provided, and are symmetrically arranged with respect to the crimping direction of the crimping mechanism.

[0024] By adopting the above technical solution, at least two knocking mechanisms are set, and the two knocking mechanisms are symmetrically arranged about the crimping mechanism, so that the force is evenly distributed when the steel anchor or aluminum tube is demoulded, which can improve the efficiency of demoulding the steel anchor or aluminum tube, and thus help improve the efficiency of wire crimping.

[0025] In a second aspect, the present application provides a wire crimping method, comprising the following crimping steps:

[0026] S1: First, use the clamping mechanism to fix the steel anchor, then pass the stranded wire through the aluminum tube, and then extend the stranded wire through the aluminum tube into the installation hole of the steel anchor;

[0027] S2: Adjust the translation mechanism, the translation mechanism drives the crimping mechanism to move to the crimping position of the steel anchor and the stranded wire, start the crimping mechanism, and crimp the steel anchor and the stranded wire;

[0028] S3: Adjust the translation mechanism, the translation mechanism drives the crimping mechanism to the crimping position of the aluminum tube and the stranded wire, start the crimping mechanism, and the crimping mechanism crimps the aluminum tube and the stranded wire.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The infrared distance measuring sensor is set to detect the possibility of the machine skipping steps due to faults (the distance the translation plate moves each time is inconsistent). The infrared distance measuring sensor sends a signal to the limit mechanism, and the limit mechanism limits and fixes the translation plate to ensure that the distance the translation plate moves is within the specification, thereby ensuring that the crimping distance of the crimping mechanism is within the specification, which helps to improve the crimping quality of the wire.

[0031] 2. Send a signal to the power part through the infrared ranging sensor, the power part moves, and the power part drives the limit block to extend into the limit groove to realize the limitation of the translation plate; when processing different wires (different wires have different crimping lengths), move the sliding block, and the sliding block moves on the limit slide bar. When the sliding block moves to the appropriate distance, adjust the fixing part, and the fixing part fixes the sliding block and the limit slide bar. In this way, by changing the distance between adjacent limit mechanisms, the crimping mechanism can be limited and fixed at a fixed interval, so that different wires can be crimped. At the same time, it also helps to prevent the crimping mechanism from skipping steps and improve the crimping quality of the wires.

[0032] 3. By turning on the lifting motor, the lifting motor drives the lifting screw to rotate, and the rotation of the lifting screw drives the bearing plate to move. The bearing plate moves on the lifting slide bar. The lifting movement of the bearing plate drives the lifting movement of the translation plate. The lifting movement of the translation plate drives the lifting movement of the crimping mechanism, which helps to adjust the stranded wire and the steel anchor to the same horizontal line, ensure the concentricity of the stranded wire and the steel anchor, and thus improve the crimping quality of the wire.

[0033] 4. By adjusting the rotating rod, the rotating rod drives the tightening rod to move. The movement of the tightening rod makes the space of the clamping groove continuously smaller, and the side wall of the clamping groove is pressed against the clamping screw to achieve the purpose of locking and limiting the clamping screw, effectively preventing the phenomenon that the clamping screw may be accidentally touched during the crimping process of the wire, resulting in the failure of clamping the twisted wire or steel anchor, affecting the crimping operation of the wire, and improving the working stability of the wire crimping equipment.

[0058] Reference Figure 10Furthermore, in some embodiments of the present disclosure, the clamping mechanism 5 also includes a limit member 55; the limit member 55 includes a limit block 551, a tightening rod 552 and a rotating rod 553; the limit block 551 is installed on the side of the fixed block 53 away from the clamping block 54, and the limit block 551 has a clamping groove 5511, part of the clamping screw 51 is located in the clamping groove 5511, and the space of the clamping groove 5511 is variable; the tightening rod 552 passes through the clamping groove 5511 and is fixedly connected to the limit block 551; the rotating rod 553 is rotatably connected to the end of the tightening rod 552, wherein the rotation axis of the rotating rod 553 and the tightening rod 552 is perpendicular to the axis of the tightening rod 73, and the rotating rod 553 moves to drive the tightening rod 552 to move, so as to realize the change of the space of the clamping groove 5511.

[0059] Specifically, when the clamping screw 51 needs to be limited and fixed, the rotating rod 553 is adjusted. The movement of the rotating rod 553 drives the clamping rod 73 to move, and the movement of the clamping rod 73 drives the limit block 551 to move. At this time, the space of the clamping groove 5511 shrinks, and the side wall of the clamping groove 5511 is pressed against the peripheral side of the clamping screw 51, thereby achieving the purpose of limiting and fixing the clamping screw 51.

[0060] Reference Figure 2 、 Figure 3 The knocking mechanism 7 includes a semi-arc disk 71, a knocking rod 72, a tightening rod 73 and a power assembly 74; the semi-arc disk 71 is rotatably connected to the crimping shell 15, and the rotation axis of the semi-arc disk 71 and the crimping shell 15 is perpendicular to the crimping direction of the crimping mechanism 1; the knocking rod 72 is connected to the upper part of the semi-arc disk 71, so that when the semi-arc disk 71 is in the first state, the upper pressure block 11 is separated from the wire under the action of the knocking rod 72; the tightening rod 73 is connected to the lower part of the semi-arc disk 71, so that when the semi-arc disk 71 is in the second state, the lower pressure block 12 is separated from the wire under the action of the tightening rod 73; the power assembly 74 is connected to the semi-arc disk 71, and is used to drive the semi-arc disk 71 to move, so as to realize that the semi-arc disk 71 is in the first state or the second state.

[0061] Specifically, the power assembly 74 is adjusted, and the power assembly 74 drives the semi-arc disk 71 to move, and the semi-arc disk 71 drives the knocking rod 72 to approach the steel anchor (or aluminum tube), and the pressing rod 73 is away from the steel anchor (or aluminum tube). At this time, the semi-arc disk 71 is in the first state, and thus, through the continuous movement of the power assembly 74, the steel anchor (or aluminum tube) and the crimping mechanism 1 can be demoulded; similarly, the power assembly 74 is adjusted, and the power assembly 74 drives the semi-arc disk 71 to move, and the semi-arc disk 71 drives the pressing rod 73 to be close to the bottom of the steel anchor (or aluminum tube), and the knocking rod 72 is away from the steel anchor (or aluminum tube).

[0062] Furthermore, in order to facilitate the crimping of wires of different specifications, in one embodiment, the clamping rod 73 has a folding structure. In this way, when processing wires with larger diameters, the clamping rod 73 can be folded in the first state. This can effectively prevent the interference between the clamping rod 73 and the wire, thereby improving the stability of the crimping equipment.

[0064] Reference Figure 2 、 Figure 3 In one embodiment of the present application, at least two knocking mechanisms 7 are provided, and are symmetrically arranged with respect to the crimping direction of the crimping mechanism 1. This can improve the demoulding efficiency of the wire, thereby helping to improve the crimping efficiency of the wire.

[0065] It is understandable that in the embodiment of the present disclosure, there is no limit on the number of knocking mechanisms 7 , as long as they are symmetrically arranged with respect to the crimping mechanism 1 .

[0066] In a second aspect, the present application provides a wire crimping method.

[0067] A wire crimping method includes the following crimping steps:

[0068] S1: First, use the clamping mechanism 5 to fix the steel anchor, then pass the stranded wire through the aluminum tube, and then extend the stranded wire through the aluminum tube into the installation hole of the steel anchor.

[0069] Specifically, the steel anchor is inserted into the clamping space, and the clamping screw 51 is rotated. The clamping screw 51 rotates, driving the oppositely arranged clamping blocks 54 to move toward each other. The clamping blocks 54 approach each other, and the clamping blocks 54 and the steel anchor are tightly pressed together, and the steel anchor is fixed between the clamping blocks 54. The stranded wire is then passed through the aluminum tube. At this time, the stranded wire and the aluminum tube both pass through the crimping space of the crimping mechanism 1. One end of the stranded wire is stripped and then inserted into the mounting hole of the steel anchor.

[0070] S2: Adjust the translation mechanism 3, the translation mechanism 3 drives the crimping mechanism 1 to move to the crimping position of the steel anchor and the stranded wire, start the crimping mechanism 1, and the crimping mechanism 1 crimps the steel anchor and the stranded wire.

[0071] Specifically, the drive motor 333 is turned on, and the drive motor 333 drives the drive gear 332 to rotate, and the drive gear 332 moves on the drive rack 331. The rotation of the drive gear 332 drives the translation plate 31 to move, and the movement of the translation plate 31 drives the crimping mechanism 1 to move. The crimping mechanism 1 moves to the connection position between the stranded wire and the steel anchor, and the crimping cylinder 14 is turned on. The crimping cylinder 14 drives the lower pressure block 12 to move, and the lower pressure block 12 approaches the upper pressure block 11, and the stranded wire and the steel anchor are crimped.

[0072] Furthermore, before crimping the steel anchor and stranded wire, the lifting motor 63 can be turned on. This drives the lifting screw 61 to rotate, which in turn drives the supporting plate 32 to move. The supporting plate 32 moves on the lifting slide 62. The lifting and lowering movement of the supporting plate 32 drives the translation plate 31 to move upward and downward, which in turn drives the crimping mechanism 1 to move upward and downward, adjusting the stranded wire and the steel anchor to the same horizontal line. This ensures the concentricity of the stranded wire and the steel anchor, thereby improving the crimping quality of the wire.

[0073] When the gear 742 is in the locked state, the driving mechanism 742 is in the locked state, and the driving mechanism 742 is in the locked state, so that the driving mechanism 742 can be turned into the locked state, thereby effectively preventing the driving mechanism 742 from sliding into the locked state.

[0074] S3: Adjust the translation mechanism 3, the translation mechanism 3 drives the crimping mechanism 1 to the crimping position of the aluminum tube and the stranded wire, start the crimping mechanism 1, and the crimping mechanism 1 crimps the aluminum tube and the stranded wire.

[0075] Specifically, the drive motor 333 is turned on, and the drive motor 333 drives the drive gear 332 to rotate, and the drive gear 332 moves on the drive rack 331. The rotation of the drive gear 332 drives the translation plate 31 to move, and the movement of the translation plate 31 drives the crimping mechanism 1 to move. The crimping mechanism 1 moves to the position where the stranded wire and the aluminum tube are to be crimped, and the crimping cylinder 14 is turned on. The crimping cylinder 14 drives the lower pressure block 12 to move, and the lower pressure block 12 approaches the upper pressure block 11, thereby achieving the purpose of crimping the stranded wire and the steel anchor.

[0076] Furthermore, before crimping the steel anchor and the stranded wire, the lifting motor 63 is turned on, and the lifting motor 63 drives the lifting screw 61 to rotate, and the rotation of the lifting screw 61 drives the supporting plate 32 to move, and the supporting plate 32 moves on the lifting slide 62. The lifting movement of the supporting plate 32 drives the lifting movement of the translation plate 31, and the lifting movement of the translation plate 31 drives the crimping mechanism 1 to lift and lower, and the stranded wire and the aluminum tube are adjusted to the same horizontal line. In this way, the concentricity of the stranded wire and the aluminum tube can be ensured, thereby improving the crimping quality of the wire.

[0077] After the first state is complete, the half-arc disk 71 drives the knocking rod 72 to move, and the knocking rod 72 approaches the aluminum tube, and the knocking rod 72 knocks the aluminum tube. Under the continuous movement of the half-arc disk 71, the knocking rod 72 continuously knocks the steel anchor, and the upper pressing block 11 is separated from the aluminum tube. In the second state, the half-arc disk 71 moves, and the half-arc disk 71 drives the tightening rod 73 to move, and the tightening rod 73 moves to the bottom of the aluminum tube, and the crimping cylinder 14 is turned on. The crimping cylinder 14 drives the lower pressing block 12 away from the upper pressing block 11. The movement of the lower pressing block 12 drives the aluminum tube to move, and the aluminum tube contacts the tightening rod 73, and the separation between the lower pressing block 12 and the aluminum tube is achieved under the action of the tightening rod 73. In this way, the purpose of automatic demoulding can be achieved, which helps to improve the crimping efficiency of the wire and also facilitates the movement of the crimping mechanism 1 to the next crimping position.
