Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a crimping machine for power engineering. Background Technology

[0002] A crimping machine for power engineering, often simply called a crimping machine or hydraulic crimping tool, is a specialized tool used to apply immense pressure to power conductors and metal connecting cables, causing them to permanently deform and securely bond together. Its core purpose is to create a low-resistance, high-mechanical-strength electrical connection between conductors and cables, which is fundamental to the safe and stable operation of power lines.

[0003] Chinese Patent No. CN222301063U discloses a crimping machine for power engineering, including a processing box. The processing box has a crimping assembly inside, which includes a motor. The output shaft of the motor passes through the processing box and is fixedly connected to a turntable. A rotating rod is fixedly connected to the top right side of the turntable. Through-hole plates are slidably connected to both sides of the processing box's inner cavity, and the rotating rod is located within the through-hole plates. This invention, by setting up the crimping assembly, can crimp cables. The motor, turntable, and rotating rod drive the through-hole plates to move up and down, which in turn pushes the pressing rod and crimping head to move up and down. The crimping head moves downwards to complete the crimping process. The limiting component automatically positions the cable before crimping, preventing cable displacement during the process and ensuring a better crimping effect.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: After the crimping machine completes the crimping, it feeds the cable forward through the upper and lower rollers. Although this provides some protection for the cable, wear and tear still occurs. Furthermore, the use of rollers for forward feeding is slow, and the cable cannot be directly removed, which affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to prevent cable wear and speed up the removal of cables after they have been connected, and to propose a crimping machine for power engineering.

[0006] The technical solution of this utility model is: a crimping machine for power engineering, including a vertical plate; and further comprising;

[0007] The power mechanism is located on the side of the vertical plate. There are two vertical plates, each located at the end of the power mechanism. The power mechanism is used to provide power for the pressing operation.

[0008] The crimping mechanism is mounted on the power mechanism and is used to crimp the cable using the mold corresponding to the cable to be crimped.

[0009] The frame has a sliding groove on its inner side, and a lower mold is slidably mounted on the sliding groove. An upper mold is mounted above the lower mold. The side of the upper mold is slidably connected to the sliding groove. The opposite surfaces of the upper and lower molds are provided with slots. The two slots are joined together to form a pressing shape. The sides of the upper and lower modules are provided with notches, which facilitate the removal of the molds and control the sliding of the molds within the frame to replace different molds to fit the corresponding cables.

[0010] Preferably, it also includes a fixing component, which includes a locking frame and a locking ring; the locking frame is disposed on the top of the vertical plate, the locking ring is rotatably disposed on the top of the locking frame, the end of the locking ring away from the locking frame is threaded with a threaded rod, the top of the threaded rod is provided with a rotating ring, and rubber pads are provided on the inner sides of both the locking ring and the locking frame.

[0011] Preferably, the power mechanism includes a linear guide rail and a linear motor; the linear guide rail is disposed on the side of the vertical plate, the linear motor is slidably disposed on the linear guide rail, and a controller is disposed inside the linear motor, which starts simultaneously when the linear motor is turned on.

[0012] Preferably, the crimping mechanism includes a crimping component and a sealing component; the crimping component is mounted on the linear motor and is used to crimp the cable after it has been crimped; the sealing component is mounted on the top of the linear motor and is used to seal the top of the frame after the cable has been placed between the upper and lower molds.

[0013] Preferably, the crimping assembly includes a hydraulic cylinder, a piston rod, and crimping pliers; the hydraulic cylinder is located at the bottom of the linear motor, the output end of the hydraulic cylinder is provided with a piston rod, the top of the piston rod is provided with crimping pliers, the bottom of the frame is connected to the top of the linear motor, and the outer side of the crimping pliers is slidably connected to the inner side of the frame.

[0014] Preferably, the closure assembly includes a closure disc, a handle, and a threaded rod II; the top of the frame has an annular notch, and the inner side of the annular notch has a slot. Two slots are symmetrically arranged about the annular notch. The closure disc is engaged with the inner side of the annular notch. The handle is located on the top of the closure disc. The threaded rod II is threaded onto the inner side of the handle. The top of the threaded rod II has a rotating ring II. The bottom of the threaded rod II has a rotatable connecting block. The side of the connecting block has a rotatable connecting rod. The end of the connecting rod away from the connecting block has a rotatable insert block. Two connecting rods are symmetrically arranged about the connecting block. When the threaded rod II moves, it drives the two connecting rods to move synchronously. The outer side of the insert block and the inner side of the closure disc are slidably connected.

[0015] Compared with the prior art, this utility model has the following beneficial technical effects: By setting up a crimping mechanism and a power mechanism, the sealing disc is clamped on the top of the frame. After being clamped, the threaded rod II is rotated to drive the insert block into the slot to complete the fixation. After the hydraulic cylinder crimps the cable at one point, it returns to its original position. The linear motor drives the crimping mechanism to move to the next position to continue crimping. After the entire cable crimping is completed, the threaded rod II is rotated in the opposite direction to remove the cable. This can directly expose the crimping area, and workers do not need to repeatedly move the cable or equipment, shortening the single operation time and significantly compressing the overall construction period. At the same time, it can avoid cable damage or equipment tipping caused by pulling, allowing the cable to detach naturally, reducing human intervention and lowering the probability of accidents such as cuts and pinches.

[0021] Example 1, as Figures 1-3 As shown, the present invention proposes a crimping machine for power engineering, which includes a vertical plate 1, a power mechanism, a crimping mechanism, and a frame 401.

[0022] The power mechanism is located on the side of the vertical plate 1. There are two vertical plates 1, each located at the end of the power mechanism. The power mechanism is used to provide power for the pressing operation.

[0023] The crimping mechanism is mounted on the power mechanism and is used to crimp the cable using the mold corresponding to the cable to be crimped.

[0024] The inner side of the frame 401 is provided with a sliding groove 411, and a lower mold 402 is slidably mounted on the sliding groove 411. An upper mold 403 is provided above the lower mold 402. The side of the upper mold 403 is slidably connected to the sliding groove 411. The opposite surfaces of the upper mold 403 and the lower mold 402 are provided with slots. The two slots are joined together to form a pressing shape. The sides of the upper module and the lower module are provided with notches. The notches facilitate the removal of the molds and control the molds to slide within the frame 401 so as to replace different molds to adapt to the corresponding cables.

[0025] The fixing assembly includes a locking frame 201 and a locking ring 202. The locking frame 201 is located on the top of the vertical plate 1, and the locking ring 202 is rotatably located on the top of the locking frame 201. The end of the locking ring 202 away from the locking frame 201 is threaded with a threaded rod 203. A rotating ring 204 is located on the top of the threaded rod 203. Rubber pads are provided on the inner sides of both the locking ring 202 and the locking frame 201 to prevent the cable from being worn during the crimping process. After opening the locking ring 202, the cable is placed on the top of the locking frame 201. Then, the locking ring 202 is rotated to press the cable down, and the rotating ring 204 drives the threaded rod 203 to rotate, so that the locking ring 202 and the locking frame 201 are connected together, thereby fixing the cable.

[0026] The power mechanism includes a linear guide rail 301 and a linear motor 302. The linear guide rail 301 is located on the side of the vertical plate 1, and the linear motor 302 is slidably mounted on the linear guide rail 301. The linear motor 302 has a controller inside. When the linear motor 302 is turned on, the controller starts simultaneously and controls the linear motor 302 to turn on intermittently, so that after crimping one section of the cable, it automatically moves to the next section, thereby completing the overall automatic crimping work.

[0027] Example 2, as Figures 1-2 As shown, this utility model proposes a crimping machine for power engineering. Compared with Embodiment 1, this embodiment details the structure of the crimping mechanism.

[0028] The crimping mechanism includes a crimping assembly and a sealing assembly. The crimping assembly is mounted on the linear motor 302 and is used to crimp the cable after it has been assembled. The sealing assembly is located on top of the linear motor 302 and is used to seal the top of the frame 401 after the cable is placed between the upper mold 403 and the lower mold 402. The crimping assembly includes a hydraulic cylinder 303, a piston rod 304, and crimping pliers 305. The hydraulic cylinder 303 is located at the bottom of the linear motor 302, and the piston rod 304 is located at the output end of the hydraulic cylinder 303. The crimping pliers 305 are located at the top of the piston rod 304. The bottom of the frame 401 is connected to the top of the linear motor 302, and the outer side of the crimping pliers 305 is slidably connected to the inner side of the frame 401. When the hydraulic cylinder 303 is activated, it moves the piston rod 304, which in turn moves the crimping pliers 305. When the crimping pliers 305 moves upward, it squeezes the lower mold 402 and the upper mold 403, thereby crimping the cable interface. The closure assembly includes a closure disc 404, a handle 405, and a threaded rod 406. The top of the frame 401 has an annular notch, and the inner side of the annular notch has two slots symmetrically arranged about the annular notch. The closure disc 404 is engaged with the inner side of the annular notch. The handle 405 is located on the top of the closure disc 404. The threaded rod 406 is threaded onto the inner side of the handle 405. The top of the threaded rod 406 has a rotating ring 407. The bottom of the threaded rod 406 has a rotatable connecting block 408. The side of the connecting block 408 has a rotatable connecting rod 409. The end of the connecting rod 409 away from the connecting block 408 has a rotatable insert 410. There are two connecting rods 409 symmetrically arranged about the connecting block 408. When the threaded rod 406 moves, it drives the two connecting rods 409. 09. The outer side of the insert 410 and the inner side of the closed disc 404 are slidably connected. The threaded rod 406 is rotated by a rotating ring. Since the threaded rod 406 is threadedly connected to the handle 405, it moves when it rotates. When the threaded rod 406 moves, it drives the connecting block 408 to move. The connecting block 408 drives the insert 410 to move through the connecting rod 409. When the threaded rod 406 moves upward, it drives the two inserts 410 to move inward synchronously through the two connecting rods 409, thereby disengaging from the slot on the frame 401. This allows the closed disc 404 to be disengaged from the frame 401. When the closed disc 404 is installed, the threaded rod 406 moves downward, causing the insert 410 to snap into the slot and fix the closed disc 404, thus sealing the top of the frame 401.

[0029] In summary, when using this utility model, the lower mold 402, the cable, and the upper mold 403 are sequentially inserted into the sliding groove 411 on the frame 401. Then, the locking ring 202 is opened, the cable is placed on top of the locking frame 201, and the locking ring 202 is rotated to press down the cable. The rotating ring 204 drives the threaded rod 203 to rotate, connecting the locking ring 202 and the locking frame 201 together, thus fixing the cable. After fixing, the sealing disc 404 is inserted into the annular notch in the frame 401. Then, the rotating ring rotates the threaded rod 406. The threaded rod 406 moves during rotation, thereby driving the connecting block 408 to move. The connecting block 408 drives the insert block 410 to move through the connecting rod 409. The threaded rod 406 moves downward, causing the insert block 410 to engage in the slot and fix the sealing disc 404, thus sealing the top of the frame 401. After sealing, the hydraulic cylinder 303 and the linear motor are activated. 302. The hydraulic cylinder 303 drives the piston rod 304 to move, and the piston rod 304 drives the crimping pliers 305 to move. When the crimping pliers 305 moves upward, it squeezes the lower mold 402 and the upper mold 403, thereby completing the crimping at the cable interface. Then, the hydraulic cylinder 303 drives the crimping pliers 305 to return to the original position. At this time, the upper mold 403 and the lower mold 402 separate from the cable. The upper mold 403 and the lower mold 402 move to the next position with the linear motor 302. The cable remains in the same position due to the restriction of the locking ring 202, so the next crimping is performed. After the overall crimping is completed, the threaded rod 206 and the threaded rod 203 are rotated in the opposite direction. After the threaded rod 203 disengages from the locking frame 201, it releases both sides of the cable. The threaded rod 206 causes the plug 410 to disengage from the slot. The closed plate 404 is taken out of the frame 401. Then, the upper mold 403, the cable and the lower mold 402 are taken out in sequence, and the next cable is crimped.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
