[0001] The invention relates to the technical field of electric power equipment manufacturing, in particular to a manufacturing device for a power cable terminal head. Background Art

[0002] With the increase of urban buildings and population density, power cables have gradually been used in large cities and rural areas. As the application of urban distribution network cable lines has gradually replaced the previous distribution overhead lines, the large-scale application of branch boxes, ring network cabinets and box transformers has made the large-scale production of cable terminal heads a reality.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

The stability of this structure and the high efficiency of the operating mechanism greatly shorten the production time of the cable head.

[0018] 3. When in use, the electric push rod is started to shrink, thereby pulling the reinforcing plate downward and driving the elastic plate downward at the same time. Since the elastic plate can slide flexibly inside the movable opening, the clamped cable can be placed between the elastic plate and the limit plate, so that the cable can be raised to prevent the cable from being at the bottom of the cutting surface of the cutting blade during cutting. During the cutting process, the electric push rod is extended, thereby driving the elastic plate to retract until the limit plate is received into the inner groove, wherein the positioning block has a position limiting function for the elastic plate, and can enable the elastic plate to slide while being parallel to the fixed back plate.

[0023] like Figure 1 As shown, the bracket 1 includes two frame frames, and a fixing plate 101 is fixedly connected between the outer surfaces of the two frame frames. The support frame assembled by the frame frames and the fixing plates 101 has the advantage of high stability and can effectively prevent the cable from tipping over and falling off during clamping and cutting.

[0024] like Figure 1As shown, the control mechanism 2 includes a programmable logic controller and a user interface connected thereto, which is used to provide human-computer interaction and realize precise control of the clamping mechanism 3 and the cutting mechanism 4. The programmable logic controller receives the parameters and instructions input by the user, and precisely controls the power device 302 and the hydraulic device 402 through the internal program, so as to ensure that the clamping mechanism 3 can accurately clamp cables of different diameters, and the cutting mechanism 4 can accurately cut the cables at a predetermined position. The user interface provides a platform for the operator to interact with the device, and can monitor and adjust the clamping and cutting parameters in real time, thereby ensuring the accuracy and controllability of the entire production process.

[0025] like Figure 2 As shown, the power device 302 is configured as a servo motor, which controls the clamping force through encoder feedback to adapt to cables of different thicknesses and materials to avoid damage to the cables. The power device 302 can adjust the clamping force in real time according to preset parameters and actual conditions to ensure that the cable is subjected to uniform and stable force during the clamping process, thereby avoiding damage or deformation of the cable due to excessive or insufficient clamping force.

[0026] like Figure 2 As shown, a sensor is provided inside the arc-shaped groove 306 of the clamping plate 305 for detecting the presence of the cable and confirming whether it is correctly clamped, thereby automatically adjusting the clamping force through the control mechanism 2. The sensor is used to detect the presence of the cable and confirm whether it is correctly clamped, thereby automatically adjusting the clamping force through the control mechanism 2. When the cable is placed in the arc-shaped groove 306 of the clamping plate 305, the sensor can detect the presence of the cable and send a signal to the control mechanism 2. After receiving the signal, the control mechanism 2 can automatically adjust the clamping force according to the preset parameters and actual conditions to ensure that the cable is correctly clamped and avoid problems caused by insufficient or excessive clamping force.

[0027] like Figure 3 As shown, the hydraulic device 402 is equipped with a pressure feedback sensor for real-time monitoring of the cutting force, and adjusting it through the control mechanism 2 to ensure cutting accuracy and repeatability. The hydraulic device 402 will adjust the cutting force according to the signal of the pressure feedback sensor to ensure that the force applied during the cutting process is appropriate and achieve precise cutting.

[0028] like Figure 3 and Figure 4As shown, the hydraulic transmission rod 403 includes two fixed seats 4031, one end of the two fixed seats 4031 is rotatably connected to the first connecting rod 4032, one end of the two first connecting rods 4032 is rotatably connected to the second connecting rod 4034 through a rotating shaft, and a connecting rod 4033 is rotatably connected between one end of the two first connecting rods 4032 through a rotating shaft. The first connecting rod 4032 and the second connecting rod 4034 are rotatably connected to each other, so that the position of the cutting blade 404 can be adjusted, and the connecting rod 4033 connects the first connecting rod 4032 and the second connecting rod 4034, so that the first connecting rod 4032 and the second connecting rod 4034 can move at the same time.

[0029] like Figure 5-8 As shown, an inner groove 408 is formed on the outer surface of the force bearing seat 407, and a movable opening 409 is formed on the inner wall of the inner groove 408. The limiting plate 410 is received in the inner groove 408 and does not affect the cutting.

[0030] like Figure 5-8 As shown, a positioning block 417 is fixedly connected to the outer surface of the fixed back plate 411, a positioning hole 418 is opened on the top of the positioning block 417, and an elastic plate 412 is slidably connected to the inner wall of the positioning hole 418. A reserved groove 416 is opened at the bottom of the elastic plate 412, and the bottom of the elastic plate 412 is fixedly connected to the limiting plate 410. The outer surface of the elastic plate 412 is slidably connected to the inner wall of the movable opening 409, and the elastic plate 412 moves downward. Since the elastic plate 412 can slide flexibly inside the movable opening 409, the clamped cable can be placed in a position between the elastic plate 412 and the limiting plate 410, so that the cable can be lifted to prevent the cable from being at the bottom of the cutting surface of the cutting blade 404 during cutting.

[0031] like Figure 5-8 As shown, the top of the elastic plate 412 is fixedly connected to a reinforcing plate 413, and electric push rods 414 are arranged at the bottom of the reinforcing plate 413 near both ends. The bottom ends of the two electric push rods 414 are fixedly connected to mounting blocks 415, and the two mounting blocks 415 are respectively fixedly installed on both sides of the cutting base 405. By starting the electric push rod 414, the electric push rod 414 is contracted, thereby pulling the reinforcing plate 413 downward.

[0032] The use method and working principle of the device are as follows: First, the power device 302 drives the outer transmission rod 303 and the inner transmission rod 304 to rotate and open or close the clamping plate 305. According to the diameter of the cable to be clamped, the arc groove 306 on the clamping plate 305 is adjusted to achieve stable clamping of the cable. The control mechanism 2 controls the hydraulic device 402 to push the hydraulic transmission rod 403 and the pressure rod 406 to move the cutting blade 404 to the predetermined cutting position of the cable, so as to achieve accurate and smooth cutting of the clamped cable. The programmable logic controller receives the parameters and instructions input by the user, and accurately controls the power device 302 and the hydraulic device 402 through the internal program to ensure that the clamping mechanism 3 can accurately clamp cables of different diameters, and the cutting mechanism 4 The cable can be precisely cut at a predetermined position. The user interface provides a platform for the operator to interact with the device. The clamping and cutting parameters can be monitored and adjusted in real time, ensuring the accuracy and controllability of the entire production process. The power device 302 controls the clamping force through encoder feedback to adapt to cables of different thicknesses and materials and avoid damage to the cables. The power device 302 can adjust the clamping force in real time according to preset parameters and actual conditions to ensure that the cable is subjected to uniform and stable force during the clamping process, thereby avoiding damage or deformation to the cable caused by excessive or insufficient clamping force. The sensor is used to detect the presence of the cable and confirm whether it is clamped correctly, thereby automatically adjusting the clamping force through the control mechanism 2. When the cable is placed on the clamping plate 30 5, the sensor can detect the presence of the cable and send a signal to the control mechanism 2. After receiving the signal, the control mechanism 2 can automatically adjust the clamping force according to the preset parameters and actual conditions to ensure that the cable is correctly clamped and avoid problems caused by insufficient or excessive clamping force. The pressure feedback sensor is used to monitor the cutting force in real time and adjust it through the control mechanism 2 to ensure cutting accuracy and repeatability. The hydraulic device 402 will adjust the cutting force according to the signal of the pressure feedback sensor to ensure that the force applied during the cutting process is appropriate and achieve accurate cutting. The control mechanism 2 will adjust the hydraulic device 402 in real time to ensure the stability and consistency of the cutting force. The cutting blade 404 is designed to be a quickly replaceable structure for convenience. In order to quickly replace blades of different types or sizes according to different cutting requirements, the operator only needs to loosen the fixing screws, remove the original blade, install the new blade and tighten the screws. This design improves cutting efficiency and flexibility, while reducing maintenance costs and downtime, and improving production efficiency and economy. By starting the electric push rod 414, the electric push rod 414 is contracted, thereby pulling the reinforcement plate 413 downward and driving the elastic plate 412 to move downward. Since the elastic plate 412 can slide flexibly inside the movable opening 409, the clamped and fixed cable can be placed in the position between the elastic plate 412 and the limit plate 410, so that the cable can be raised to avoid the cable being at the bottom of the cutting surface of the cutting blade 404 during cutting.During the cutting process, the electric push rod 414 extends, thereby driving the elastic plate 412 to retract until the limiting plate 410 is received in the inner groove 408, wherein the positioning block 417 has a position limiting function for the elastic plate 412, and can make the elastic plate 412 slide while being parallel to the fixed back plate 411.

The model is selected according to the actual use, so the control method and wiring layout of the control mechanism 2, power device 302, hydraulic device 402 and electric push rod 414 will not be explained in detail.
