Description
Technical Field
[0001] This invention relates to the field of cable repair equipment technology, specifically to an auxiliary device for the inspection and installation of power equipment. Background Technology
[0002] Power equipment refers to the general term for all kinds of machines, devices and facilities involved in the entire process of power production, transmission, distribution, conversion and consumption. Cables are commonly used equipment in power systems. They are the channels and carriers for transmitting electrical energy from one point to another. They are often used in power distribution systems, facilities and other power distribution switch control equipment. When high-voltage cables malfunction and are repaired, cutters, strippers, hydraulic pliers, high-voltage cutters, insulating tape and heat shrink tubing are usually used to cut, strip and crimp the cables to complete the cable repair and connection.
[0003] When connecting high-voltage cable conductors, hydraulic crimping pliers are often used to crimp the terminals. The common crimping shape is usually hexagonal. However, when the hydraulic crimping pliers use a dynamic crimping die to crimp the terminals, the terminal material is prone to plastic deformation under great pressure. It may become tightly embedded in the corner of the static crimping die, making it difficult to separate the terminal from the static crimping die. It may be necessary to pry it forcibly to separate the terminal from the static crimping die, which affects the crimping efficiency. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides an auxiliary device for the maintenance and installation of power equipment, including a hydraulic clamp body, and a rotating frame rotatably connected to the top of the hydraulic clamp body; A crimping mechanism is fixedly installed on the side wall of the rotating frame and is used to crimp terminals. The locking mechanism is slidably disposed on the inner wall of the crimping mechanism to reduce the adhesion between the terminal and the crimping mechanism; A separation mechanism is fixedly installed on the side wall of the crimping mechanism and is used to push the terminal to separate from the crimping mechanism; In use, the crimping mechanism is placed on the outer wall of the terminal. Then, the crimping mechanism is moved by the hydraulic clamp body to squeeze the terminal. During the squeezing process, the adhesion of the terminal is reduced by the locking mechanism. Finally, the terminal is moved by the separating mechanism.
[0005] Preferably, the crimping mechanism includes: The extrusion assembly is fixedly mounted on the side wall of the rotating frame by fasteners; The fasteners include a static pressure mold fixedly connected to the side wall of the rotating frame, and a dynamic pressure mold slidably connected to the inner wall of the hydraulic clamp body; A rotating assembly is rotatably mounted on the inner wall of the static pressure mold; During the crimping of terminals, pressing the hydraulic clamp body pushes the crimping component to move, causing the dynamic die to move towards the static die and crimp the terminals.
[0006] Preferably, the locking mechanism includes: The bonding component is slidably disposed on the inner wall of the static pressure mold; A blocking component is slidably disposed on the inner wall of the dynamic pressure mold; When the extrusion component moves, it drives the rotation component to rotate, which in turn drives the bonding component to move and bond with the terminal. Then, the blocking component reduces the flash at the joint of the dynamic and static molds.
[0007] Preferably, the separation mechanism includes: Steering assembly, which is fixedly installed on the outer wall of the static pressure mold; A reset assembly is fixedly installed on the outer wall of the dynamic pressure mold. In this process, after the dynamic die moves to press the terminal, when the dynamic die needs to return to its original position and separate from the terminal, the terminal will be pushed to separate from the static die by the steering component and the reset component.
[0008] Preferably, the extrusion assembly includes a positioning rod slidably connected to the inner wall of the hydraulic clamp body, and the outer wall of the positioning rod is slidably connected to the inner wall of the rotating frame; The construction workers remove the positioning rod from the hydraulic clamp body and the rotating frame. Then, they rotate the rotating frame to move the static mold and the dynamic mold away from each other. After the rotating frame is in place, they move the hydraulic clamp body to bring the dynamic mold closer to the terminal block. After it is in place, they rotate the rotating frame again to reset it, so that the static mold moves closer to the dynamic mold. After it is in place, they insert the positioning rod back into the rotating frame and the hydraulic clamp body to fix them. Then, they press the hydraulic clamp body repeatedly to move the dynamic mold towards the static mold.
[0009] Preferably, the rotating assembly includes an arc-shaped block rotatably connected to the inner wall of the static pressure mold, an arc-shaped spring rod fixedly connected to the inner wall of the static pressure mold, and the outer wall of the arc-shaped spring rod slidably connected to the inner wall of the arc-shaped block. During the movement of the dynamic pressure mold, the dynamic pressure mold will come into contact with the arc-shaped block, push the arc-shaped block to rotate, squeeze the arc-shaped spring rod, and cause the arc-shaped spring rod to accumulate rebound force.
[0010] Preferably, the bonding component includes six separation grooves formed in the inner wall of the static pressure mold, and bonding blocks are slidably connected to the inner walls of the six separation grooves; Each of the six bonding blocks is fixedly connected to a spring return rod on its side wall, and the outer wall of each of the six spring return rods is slidably connected to the inner wall of the static pressure mold. When the arc-shaped block rotates, the inclined surface of the arc-shaped block will press against the arc surface of the spring return rod, pushing the spring return rod and the bonding block to move. This causes the spring return rod to be compressed and accumulate rebound force. When the inclined surface of the arc-shaped block separates from the spring return rod, the spring return rod and the bonding block will stop moving. At this time, the bonding block will be in contact with the side wall of the static pressure mold.
[0011] Preferably, the blocking component includes an annular groove formed on the inner wall of the dynamic mold and the static mold, and four sliding grooves are formed on the inner wall of the dynamic mold; Four blocking blocks are fixedly connected to the side wall of the static pressure mold, and the outer walls of the four blocking blocks are slidably connected to the inner walls of the four sliding grooves. Among them, when the dynamic mold moves, the blocking block will also enter the sliding groove to block the mold closing point of the dynamic mold and the static mold; Afterwards, the dynamic die will press the terminal, making the terminal and wire fit tightly together. During the pressing process, the terminal will undergo plastic deformation. The deformed material will flow towards the part where the dynamic die and static die are not fully fitted. The material flowing outward is blocked by the blocking block. At the same time, since the dynamic die and static die have annular grooves inside, space is provided for the terminal material to flow. By blocking the terminal material from flowing outward, some material will flow into the annular groove, thus reducing the flash generated during crimping and reducing the adhesion at the part of the dynamic die and static die. After crimping is completed, the hydraulic clamp body moves the dynamic die away from the static die, which will separate the dynamic die and the arc block. At this time, the rebound force of the arc spring rod will be released, thus separating the arc spring rod from the spring return rod. The rebound force of the spring return rod will be released again, causing the spring return rod and the bonding block to return to their original positions, separating the bonding block from the corner of the terminal. By reducing the flash and adhesion between the dynamic and static molds at the joint, and simultaneously reducing the adhesion between the static mold corner and the terminal, the terminal can be quickly separated from the static mold. This effectively prevents the terminal from being too tightly attached to the static mold, making separation difficult and requiring prying forcible separation, which is time-consuming and labor-intensive. Since a high-voltage cable has multiple conductors that need to be connected, and a terminal needs to be crimped multiple times, the crimping process is faster and the crimping efficiency is increased.
[0012] Preferably, the steering assembly includes inclined blocks fixedly connected to the front and back of the static mold, and rotating plates rotatably connected to both the front and back of the dynamic mold. When the dynamic die moves toward the static die, it also drives the rotating plate to move. As the rotating plate continues to move, it comes into contact with the inclined surface of the inclined block, which causes the rotating plate to be squeezed and rotate.
[0013] Preferably, the reset assembly includes a fixed plate fixedly connected to the front and back of the dynamic pressure mold, and a reset spring is fixedly connected to the side wall of each of the two fixed plates. The bottom of each of the two reset springs is fixedly connected to the top of the two rotating plates. During the rotation of the plate, the return spring is compressed, allowing it to accumulate restoring force. As the plate continues to rotate, two situations occur: when the terminal is in contact with the static mold but not with the dynamic mold, the plate will contact the terminal, pushing it towards the dynamic mold; when the terminal is in contact with the dynamic mold and is in contact with the static mold, the plate will not contact the terminal and can rotate smoothly. As the plate continues to rotate, it will move to the bottom of the inclined block, at which point it will stop rotating. When the dynamic mold and the static mold are in contact, the rotating plate is in a state of separation from the terminal. When the dynamic mold returns to its original position, it will drive the rotating plate to return to its original position. At this time, the rotating plate will be blocked by the bottom of the inclined block. As the rotating plate continues to move, the rotating plate will come into contact with the terminal. Since the dynamic mold has already separated from the terminal by a certain distance when it returns to its original position, it will also cause the arc block to return to its original position by a certain distance. The inclined surface of the arc block will come into contact with the spring return rod again, causing the spring return rod to return to its original position by a certain distance, so that the corner of the bonding block and the terminal are separated.
[0014] The present invention has the following beneficial effects: (1) When using this invention, the construction personnel bring the static pressure mold and the dynamic pressure mold close to the terminal block. After moving them into place, the dynamic pressure mold moves towards the static pressure mold by repeatedly pressing the hydraulic clamp body. During the movement of the dynamic pressure mold, the blocking component will block the mold closing point of the dynamic pressure mold and the static pressure mold. Then, the dynamic pressure mold will squeeze the terminal and press the terminal and the wire tightly together. After the pressing is completed, the hydraulic clamp body will move the dynamic pressure mold away from the static pressure mold. The bonding component will separate the bonding block from the corner of the terminal. By reducing the flash generated at the mold closing point of the dynamic pressure mold and the static pressure mold and the adhesion between the two, and at the same time reducing the adhesion between the corner of the static pressure mold and the terminal, the terminal and the static pressure mold can be separated quickly. This effectively prevents the terminal and the static pressure mold from being too tightly attached and difficult to separate, requiring prying to force separation, which is time-consuming and labor-intensive. Since there are multiple wires in a high-voltage cable that need to be connected and a terminal needs to be pressed multiple times, the pressing is faster and the pressing efficiency is accelerated.
[0015] (2) When the dynamic pressing mold moves towards the static pressing mold, it will also drive the rotating plate to move. As the rotating plate continues to move, it will contact the inclined surface of the inclined block, thereby squeezing the rotating plate and causing it to rotate. This causes the rotating plate to squeeze the return spring, allowing the return spring to accumulate rebound force. As the rotating plate continues to rotate, it will move to the bottom of the inclined block. When the dynamic pressing mold returns to its original position, it will drive the rotating plate to return to its original position. The rotating plate will then push the terminal to move, causing the terminal to separate from the static pressing mold. This achieves automatic separation of relatively loose terminals, effectively preventing the corner of the terminal from separating from the static pressing mold. Other positions still have a certain adhesion to the terminal, which may require the construction personnel to shake the hydraulic clamp body multiple times to fully separate the static pressing mold from the terminal. This reduces the number of shaking operations, allowing the construction personnel to directly move the hydraulic clamp body to the next crimping point, further accelerating the crimping efficiency.
[0016] (3) When the terminal is crimped, the sliding groove blocks the flash at the mold closing point from flowing outward, and the annular groove provides space for the material of the terminal to flow, so that the flash at the mold closing point of the dynamic and static pressing molds is smaller, which makes the construction personnel grind the flash of the terminal faster and reduces the grinding time. This effectively prevents the need for multiple wires to be connected inside the high-voltage cable and the need for multiple crimping of the terminals of each connecting wire. By reducing the flash, the construction personnel can speed up the removal time, thereby speeding up the connection of wires in the cable and speeding up the overall construction efficiency.
[0017] (4) By controlling the size of the crimping flash, the present invention effectively prevents the large gap that may exist at the joint of the dynamic and static molds during the process of the dynamic mold approaching the static mold. Under the action of the extrusion force, the terminal will deform and the deformed material will flow outward from the gap, resulting in a large flash. This causes a lot of material to be squeezed out at this position of the terminal. After subsequent grinding and repair of the flash, it is easy to make the local area thinner. The thinner area is easily broken down by the flowing current, which will reduce the service life of the cable joint. This makes the thickness of the crimped terminal more uniform at each position.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1, please refer to Figures 1-5 The present invention is an auxiliary device for the maintenance and installation of power equipment, including a hydraulic clamp body 13, and a rotating frame 14 rotatably connected to the top of the hydraulic clamp body 13. The crimping mechanism 1 is fixedly installed on the side wall of the rotating frame 14 and is used to crimp the terminals. The locking mechanism 2 is slidably disposed on the inner wall of the crimping mechanism 1 to reduce the adhesion between the terminal and the crimping mechanism 1. Separation mechanism 3 is fixedly installed on the side wall of crimping mechanism 1 and is used to push the terminal to separate from crimping mechanism 1; In use, the crimping mechanism 1 is placed on the outer wall of the terminal. Then, the crimping mechanism 1 is pushed to move by the hydraulic clamp body 13 to squeeze the terminal. During the squeezing process, the adhesion of the terminal is reduced by the locking mechanism 2. Finally, the terminal is pushed to move by the separating mechanism 3.
[0023] The crimping mechanism 1 includes: The extrusion assembly 11 is fixedly mounted on the side wall of the rotating frame 14 by a fastener; The fasteners include a static pressure mold 112 fixedly connected to the side wall of the rotating frame 14, and a dynamic pressure mold 111 slidably connected to the inner wall of the hydraulic clamp body 13. Rotating assembly 12 is rotatably disposed on the inner wall of static pressure mold 112; During the crimping of the terminal, the hydraulic clamp body 13 is pressed to push the crimping assembly 11 to move, causing the dynamic crimping die 111 to move toward the static crimping die 112 to crimp the terminal.
[0024] Card-connecting mechanism 2 includes: The bonding component 21 is slidably disposed on the inner wall of the static pressure mold 112; The blocking component 22 is slidably disposed on the inner wall of the dynamic pressure mold 111; When the extrusion component 11 moves, it will push the rotation component 12 to rotate, push the bonding component 21 to move and bond with the terminal, and then reduce the flash at the mold closing point of the dynamic mold 111 and the static mold 112 by the blocking component 22.
[0025] Separation mechanism 3 includes: Steering assembly 31 is fixedly installed on the outer wall of static pressure mold 112; Reset component 32 is fixedly installed on the outer wall of dynamic pressure mold 111; When the dynamic pressure mold 111 moves to press the terminal and needs to return to its original position to separate from the terminal, the terminal will be pushed to separate from the static pressure mold 112 by the steering component 31 and the reset component 32.
[0026] Example 2, please refer to Figures 3-11 The present invention is an auxiliary device for the maintenance and installation of power equipment. Based on Example 1, the extrusion assembly 11 includes a positioning rod 113 that is slidably connected to the inner wall of the hydraulic clamp body 13, and the outer wall of the positioning rod 113 is slidably connected to the inner wall of the rotating frame 14. The construction workers remove the positioning rod 113 from the hydraulic clamp body 13 and the rotating frame 14. Then, they rotate the rotating frame 14 to move the static mold 112 and the dynamic mold 111 away from each other. After the rotating frame 14 is rotated into place, the hydraulic clamp body 13 is moved to bring the dynamic mold 111 closer to the terminal block. After it is moved into place, the rotating frame 14 is rotated back to its original position to move the static mold 112 closer to the dynamic mold 111. After it is rotated into place, the positioning rod 113 is inserted back into the rotating frame 14 and the hydraulic clamp body 13 to fix them. Then, by repeatedly pressing the hydraulic clamp body 13, the dynamic mold 111 is moved towards the static mold 112.
[0027] The rotating assembly 12 includes an arc-shaped block 121 rotatably connected to the inner wall of the static pressure mold 112, an arc-shaped spring rod 122 fixedly connected to the inner wall of the static pressure mold 112, and the outer wall of the arc-shaped spring rod 122 slidably connected to the inner wall of the arc-shaped block 121. During the movement of the dynamic pressure mold 111, the dynamic pressure mold 111 will contact the arc-shaped block 121, push the arc-shaped block 121 to rotate, squeeze the arc-shaped spring rod 122, and cause the arc-shaped spring rod 122 to accumulate rebound force.
[0028] The bonding component 21 includes six separation grooves 211 formed on the inner wall of the static pressure mold 112, and bonding blocks 212 are slidably connected to the inner walls of the six separation grooves 211. Each of the six bonding blocks 212 has a spring return rod 213 fixedly connected to its side wall, and the outer wall of each of the six spring return rods 213 is slidably connected to the inner wall of the static pressure mold 112. When the arc-shaped block 121 rotates, its inclined surface presses against the arc surface of the spring return rod 213, pushing the spring return rod 213 and the mating block 212 to move. This causes the spring return rod 213 to be compressed and accumulate rebound force. When the inclined surface of the arc-shaped block 121 separates from the spring return rod 213, the spring return rod 213 and the mating block 212 will stop moving. At this time, the mating block 212 will be in contact with the side wall of the static pressure mold 112. Figure 7 As shown.
[0029] The blocking assembly 22 includes an annular groove 221 formed on the inner wall of the dynamic mold 111 and the static mold 112, and four sliding grooves 222 are formed on the inner wall of the dynamic mold 111. Four blocking blocks 223 are fixedly connected to the side wall of the static pressure mold 112, and the outer walls of the four blocking blocks 223 are slidably connected to the inner walls of the four sliding grooves 222. When the dynamic mold 111 moves, the blocking block 223 will also enter the sliding groove 222 to block the mold closing point of the dynamic mold 111 and the static mold 112. Subsequently, the dynamic die 111 presses the terminal, crimping the terminal tightly against the wire. During the pressing process, the terminal undergoes plastic deformation. The deformed material flows towards the part where the dynamic die 111 and the static die 112 are not fully joined. The blocking block 223 blocks the outward flow of material. At the same time, since the dynamic die 111 and the static die 112 have annular grooves 221 inside, they provide space for the terminal material to flow. By blocking the outward flow of terminal material, some material will flow into the annular grooves 221, thus generating during crimping. The smaller flash reduces the adhesion between the dynamic mold 111 and the static mold 112 at the mold joint. After pressing, the hydraulic clamp body 13 moves the dynamic mold 111 away from the static mold 112, causing the dynamic mold 111 and the arc block 121 to separate. At this time, the rebound force of the arc spring rod 122 is released, causing the arc spring rod 122 to separate from the spring return rod 213. The rebound force of the spring return rod 213 is then released again, causing the spring return rod 213 and the bonding block 212 to return to their original positions, separating the bonding block 212 from the corner of the terminal. By reducing the flash generated at the joint of the dynamic pressing mold 111 and the static pressing mold 112 and the adhesion between them, and at the same time reducing the adhesion between the corner of the static pressing mold 112 and the terminal, the terminal can be quickly separated from the static pressing mold 112. This effectively prevents the terminal from being too tightly attached to the static pressing mold 112 and difficult to separate, requiring prying to force separation, which is time-consuming and labor-intensive. Since there are multiple wires in a high-voltage cable that need to be connected, and a terminal needs to be crimped multiple times, the crimping is made faster and the crimping efficiency is increased.
[0030] The steering assembly 31 includes inclined blocks 311 fixedly connected to the front and back of the static mold 112, and rotating plates 312 rotatably connected to both the front and back of the dynamic mold 111. When the dynamic pressing mold 111 moves toward the static pressing mold 112, it also drives the rotating plate 312 to move. As the rotating plate 312 continues to move, it will come into contact with the inclined surface of the inclined stop block 311, thereby causing the rotating plate 312 to be squeezed and rotate.
[0031] The reset assembly 32 includes a fixed plate 321 fixedly connected to the front and back of the dynamic pressure mold 111. A reset spring 322 is fixedly connected to the side wall of each of the two fixed plates 321. The bottom of each of the two reset springs 322 is fixedly connected to the top of the two rotating plates 312. When the rotating plate 312 rotates, it compresses the return spring 322, allowing the return spring 322 to accumulate restoring force. As the rotating plate 312 continues to rotate, two situations occur: when the terminal is in contact with the static mold 112 but not with the dynamic mold 111, the rotating plate 312 will contact the terminal, pushing the terminal towards the dynamic mold 111. When the terminal is in contact with the dynamic mold 111 and in contact with the static mold 112, the rotating plate 312 will not contact the terminal and can rotate smoothly. Figure 9 As shown in the position of G, as the rotating plate 312 continues to rotate, the rotating plate 312 will move to the bottom of the inclined block 311, at which point the rotating plate 312 will stop rotating. When the dynamic mold 111 and the static mold 112 are in contact, the rotating plate 312 is in a state separated from the terminal, such as Figure 10 As shown, when the dynamic pressure mold 111 returns to its original position, it will drive the rotating plate 312 to return to its original position. At this time, the rotating plate 312 will be blocked by the bottom of the inclined stop block 311. As the rotating plate 312 continues to move, it will contact the terminal, as shown. Figure 11 As shown in the position of H, when the dynamic pressure mold 111 returns to its original position, it has already separated from the terminal by a certain distance, and the arc block 121 will also return to its original position by a certain distance. The inclined surface of the arc block 121 will contact the spring reset rod 213 again, causing the spring reset rod 213 to return to its original position by a certain distance, so that the bonding block 212 separates from the corner of the terminal.
[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.
[0033] A specific application of this embodiment is as follows: When using this invention, the construction worker removes the positioning rod 113 from the hydraulic clamp body 13 and the rotating frame 14. Then, the worker turns the rotating frame 14 to rotate, causing the static pressure mold 112 and the dynamic pressure mold 111 to move away from each other. After the rotating frame 14 is rotated into place, the worker moves the hydraulic clamp body 13 to move the dynamic pressure mold 111 closer to the terminal block. After it is moved into place, the worker turns the rotating frame 14 to reset, causing the static pressure mold 112 to move closer to the dynamic pressure mold 111. After it is rotated into place, the worker inserts the positioning rod 113 back into the rotating frame 14 and the hydraulic clamp body 13 to fix them. Then, by repeatedly pressing the hydraulic clamp body 13, the worker moves the dynamic pressure mold 111 towards the static pressure mold 112. During the movement of the dynamic pressure mold 111, the dynamic pressure mold 111 will contact the arc-shaped block 121, pushing the arc-shaped block 121 to rotate and compress the arc-shaped spring rod 122, causing the arc-shaped spring rod 122 to accumulate rebound force. When the arc-shaped block 121 rotates, the inclined surface of the arc-shaped block 121 will compress the arc surface of the spring return rod 213, pushing the spring return rod 213 and the fitting block 212 to move, causing the spring return rod 213 to be compressed and accumulate rebound force. When the inclined surface of the arc-shaped block 121 separates from the spring return rod 213, the spring return rod 213 and the fitting block 212 will stop moving. At this time, the fitting block 212 will be in contact with the side wall of the static pressure mold 112, such as Figure 7 As shown, at the same time, when the dynamic mold 111 moves, the blocking block 223 will also enter the sliding groove 222 to block the mold closing point of the dynamic mold 111 and the static mold 112. Subsequently, the dynamic die 111 presses the terminal, crimping the terminal tightly against the wire. During the pressing process, the terminal undergoes plastic deformation. The deformed material flows towards the part where the dynamic die 111 and the static die 112 are not fully joined. The blocking block 223 blocks the outward flow of material. At the same time, since the dynamic die 111 and the static die 112 have annular grooves 221 inside, they provide space for the terminal material to flow. By blocking the outward flow of terminal material, some material will flow into the annular grooves 221, thus generating during crimping. The smaller flash reduces the adhesion between the dynamic mold 111 and the static mold 112 at the mold joint. After pressing, the hydraulic clamp body 13 moves the dynamic mold 111 away from the static mold 112, causing the dynamic mold 111 and the arc block 121 to separate. At this time, the rebound force of the arc spring rod 122 is released, causing the arc spring rod 122 to separate from the spring return rod 213. The rebound force of the spring return rod 213 is then released again, causing the spring return rod 213 and the bonding block 212 to return to their original positions, separating the bonding block 212 from the corner of the terminal. By reducing the flash generated at the joint of the dynamic pressing mold 111 and the static pressing mold 112 and the adhesion between them, and at the same time reducing the adhesion between the corner of the static pressing mold 112 and the terminal, the terminal and the static pressing mold 112 can be separated quickly. This effectively prevents the terminal and the static pressing mold 112 from being too tightly attached and difficult to separate, requiring prying to force separation, which is time-consuming and labor-intensive. Since there are multiple wires in a high-voltage cable that need to be connected, and a terminal needs to be crimped multiple times, the crimping is made faster and the crimping efficiency is increased. Secondly, as the dynamic pressing mold 111 moves towards the static pressing mold 112, it also drives the rotating plate 312 to move. With the continuous movement of the rotating plate 312, it contacts the inclined surface of the inclined stop block 311, causing the rotating plate 312 to be compressed and rotate. This causes the rotating plate 312 to compress the return spring 322, allowing the return spring 322 to accumulate restoring force. As the rotating plate 312 continues to rotate, two situations occur: when the terminal contacts the static pressing mold 112 but not the dynamic pressing mold 111, the rotating plate 312 will contact the terminal, pushing the terminal towards the dynamic pressing mold 111; when the terminal contacts the dynamic pressing mold 111 and is in contact with the static pressing mold 112, the rotating plate 312 will not contact the terminal and can rotate smoothly. Figure 9 As shown in the position of G, as the rotating plate 312 continues to rotate, the rotating plate 312 will move to the bottom of the inclined block 311, at which point the rotating plate 312 will stop rotating. When the dynamic mold 111 and the static mold 112 are in contact, the rotating plate 312 is in a state separated from the terminal, such as Figure 10 As shown, when the dynamic pressure mold 111 returns to its original position, it will drive the rotating plate 312 to return to its original position. At this time, the rotating plate 312 will be blocked by the bottom of the inclined stop block 311. As the rotating plate 312 continues to move, it will contact the terminal, as shown. Figure 11 As shown in the position of H, when the dynamic pressure mold 111 returns to its original position, it has already separated from the terminal by a certain distance, and the arc block 121 will also return to its original position by a certain distance. The inclined surface of the arc block 121 will contact the spring reset rod 213 again, causing the spring reset rod 213 to return to its original position by a certain distance, so that the bonding block 212 separates from the corner of the terminal. At this time, the rotating plate 312 contacts the terminal. As the rotating plate 312 returns to its original position with the moving mold 111, it will push the terminal to move, causing the terminal to separate from the static mold 112. This achieves automatic separation of the relatively loose terminal, effectively preventing the corner of the terminal from separating from the static mold 112. Other positions may still have a certain adhesion to the terminal, which may require the construction personnel to shake the hydraulic clamp body 13 multiple times to fully separate the static mold 112 from the terminal. This reduces the number of shaking operations, allowing the construction personnel to directly move the hydraulic clamp body 13 to the next crimping point, further accelerating the crimping efficiency. Secondly, during terminal crimping, the sliding groove 222 blocks the outward flow of burrs at the mold closing point, and the annular groove 221 provides space for the flow of terminal material, making the burrs at the mold closing point of the dynamic mold 111 and the static mold 112 smaller. This allows construction workers to grind the burrs of the terminals faster and reduces the grinding time. It effectively prevents the need for multiple crimping of terminals in high-voltage cables where multiple conductors need to be connected and each conductor terminal needs to be crimped multiple times. By reducing the burrs, the cleaning time for construction workers can be accelerated, thereby speeding up the connection of conductors in the cable and improving the overall construction efficiency. Secondly, by controlling the size of the crimping flash, it effectively prevents a large gap from existing at the joint of the dynamic crimping die 111 and the static crimping die 112 during the process of the two dies closing. Under the action of extrusion pressure, the terminal will deform, and the deformed material will easily flow outward from this gap, resulting in a large flash. This causes more material to be squeezed out at this position of the terminal. After subsequent grinding and repair of the flash, it is easy for this area to become thinner. The thinner area is easily broken down by the flowing current, which will reduce the service life of the cable joint. This makes the thickness of the crimped terminal more uniform at all positions.
