Description
Technical Field
[0001] This utility model relates to the field of crimping machine technology, and in particular to a crimping machine for power engineering. Background Technology
[0002] A "crimping machine for power engineering" is a type of mechanical equipment specifically used in power engineering construction. Its main function is to crimp cables, wires, and various conductors. The purpose of crimping is to securely and reliably connect conductors and connectors such as crimp terminals, connecting plates, and joints, ensuring the safe and stable operation of the power system.
[0003] Chinese patent publication: A crimping machine for power engineering, patent announcement number: CN218958237U. This patent "includes a crimping table, the surface of which has a sliding opening, a sliding block slidably connected to the inner wall of the sliding opening, and a sliding plate fixedly connected to one side of the sliding block. This utility model has a reasonable structure. By rotating the adjusting screw, it rotates within the adjusting screw hole, thereby bringing one end of the adjusting screw close to the limiting post. The DD direct drive motor drives the transmission gear to rotate via the transmission rod, and engages with the transmission gear plate to move downwards, thereby linking the sliding plate to slide within the sliding opening via the sliding block. At the same time, the sliding plate moves..."
[0004] While this equipment can protect cables by adjusting the length of the adjusting screw according to the cable diameter, the crimping machine lacks a dedicated clamping mechanism for positioning and securing the cable. This makes the cable prone to shaking or displacement during crimping, failing to ensure accurate alignment between the crimping component and the cable end. Consequently, crimping quality is affected, leading to issues such as weak crimping or uneven pressure. Furthermore, the unsecured cable may slip due to uneven force applied by the operator or external interference, increasing operational difficulty and safety risks. This hinders work efficiency and the stability of the construction site. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a crimping machine for power engineering, so as to solve the problem that the cable is prone to shaking or positional deviation during the crimping process, which makes it impossible to ensure accurate alignment between the crimping component and the cable end, thereby affecting the crimping quality and easily causing problems such as weak crimping or uneven pressure.
[0006] To achieve the above objectives, this utility model provides a crimping machine for power engineering, comprising a base plate, a support frame fixedly connected to the top of the base plate, a stabilizing rod fixedly connected between the top of the base plate and the bottom of the support frame, a lower pressing block slidably connected to the outer wall of the stabilizing rod, a hydraulic rod fixedly connected to the top of the support frame, the output end of the hydraulic rod penetrating the bottom of the support frame and fixedly connected to the top of the lower pressing block, a movable block slidably connected to the top of the base plate, a clamping mechanism for clamping and fixing cables provided on the top of the movable block, an installation block fixedly connected to the bottom of the lower pressing block, an upper pressing connector installed at the bottom of the installation block, a lower pressing connector installed at the top of the movable block, and replacement mechanisms for replacing the upper and lower pressing connectors provided on the top of the movable block and inside the installation block.
[0007] Preferably, the clamping mechanism includes two sliding plates slidably connected to the top of the base plate. The two sliding plates are fixedly connected to both sides of the moving block. Sleeves are fixedly connected to both sides of the pressing block. Rollers are rotatably connected to the bottom of the sleeves via connecting rods. The rollers are slidably connected in push grooves, which are inclined. A through groove is opened at the top of the moving block. Two clamping blocks are slidably connected inside the through groove. The two clamping blocks are arranged opposite each other, and the opposite sides of the two clamping blocks are arc-shaped. Guide rods are fixedly connected to the bottom of each clamping block. Two guide grooves are opened at the top of the base plate. The two guide grooves are Z-shaped. The guide rods at the bottom of the two clamping blocks slide inside the two guide grooves respectively.
[0008] Preferably, the replacement mechanism includes a groove formed at the bottom of the mounting block, with two opposing sliders slidably connected inside the groove. Springs are fixedly connected to the side walls of both sliders and fixedly connected to the inner wall of the groove. Opposing locking plates are fixedly connected to the bottom of both sliders.
[0009] Preferably, the top of the upper pressure connector has two engaging grooves, and the outer walls of the two engaging plates are respectively adapted to the inner walls of the two engaging grooves.
[0010] Preferably, a replacement push plate is slidably connected to the side wall of the mounting block, and one end of the replacement push plate is in contact with the opposite side of the two sliders.

The two sleeve rods are respectively distributed on both sides of the lower pressure block, and the sleeve blocks on both sides of the lower pressure block are respectively fitted onto the outer walls of the two sleeve rods.
[0012] Preferably, the opposite sides of the two sliders and the end of the replacement push plate near the inside of the groove are both arc-shaped.
[0013] The beneficial effects of this utility model are:
[0014] 1. This power engineering crimping machine, through the coordinated operation of sliding plates, clamping blocks, guide rods, and guide grooves in its clamping mechanism, achieves automatic clamping and positioning of cables, effectively solving the problem of traditional crimping machines failing to secure cables. Two sliding plates are connected to both sides of the moving block, sliding in inclined grooves with the help of rollers. This causes the moving block to slide on top of the base plate, thereby bringing the two clamping blocks in the groove closer together to clamp the cable. Guide rods are located at the bottom of the clamping blocks, slidingly connected to two Z-shaped guide grooves, providing guidance control during movement. This ensures accurate alignment and stable approach of the two clamping blocks. Furthermore, the opposing surfaces of the clamping blocks are designed with an arc shape, increasing the contact area with the cable's outer wall, enhancing clamping stability, preventing cable swaying or displacement, providing a reliable positioning basis for subsequent crimping operations, and improving crimping accuracy and safety.
[0015] 2. This power engineering crimping machine features a quick-change structure consisting of a replaceable push plate, slider, spring, locking plate, and locking groove. This allows for convenient disassembly and assembly of upper or lower crimping joints, avoiding the cumbersome and time-consuming operation of traditional crimping machines when changing crimping molds. The arc-shaped end of the push plate mates with the arc-shaped surface of the slider, pushing the slider to compress the spring and disengage the locking plate from the locking groove, thus quickly releasing the mold. During installation, the locking plate automatically engages with the locking groove under the restoring force of the spring, completing the self-locking positioning of the mold. This improves the efficiency and ease of use of the equipment, ensuring the safety and connection stability during the replacement process. Attached Figure Description

[0025] like Figures 1 to 4 As shown, a crimping machine for power engineering includes a base plate 1, a support frame 2 fixedly connected to the top of the base plate 1, a stabilizing rod 3 fixedly connected between the top of the base plate 1 and the bottom of the support frame 2, a lower pressing block 4 slidably connected to the outer wall of the stabilizing rod 3, a hydraulic rod 5 fixedly connected to the top of the support frame 2, the output end of the hydraulic rod 5 passing through the bottom of the support frame 2 and fixedly connected to the top of the lower pressing block 4, a movable block 6 slidably connected to the top of the base plate 1, a clamping mechanism for clamping and fixing cables provided on the top of the movable block 6, an mounting block 7 fixedly connected to the bottom of the lower pressing block 4, an upper pressing connector 8 installed at the bottom of the mounting block 7, a lower pressing connector 9 installed on the top of the movable block 6, and replacement mechanisms for replacing the upper pressing connector 8 and the lower pressing connector 9 provided on the top of the movable block 6 and inside the mounting block 7.
[0026] Further, see attached document. Figures 1 to 3As shown, the clamping mechanism includes two sliding plates 10, which are slidably connected to the top of the base plate 1. The two sliding plates 10 are fixedly connected to both sides of the moving block 6. Both sides of the pressing block 4 are fixedly connected to sleeve blocks 17. The bottom of the sleeve blocks 17 is rotatably connected to rollers 12 via connecting rods. The rollers 12 are slidably connected in the push groove 11. The top of the moving block 6 has a through groove 13. Two clamping blocks 14 are slidably connected inside the through groove 13. The two clamping blocks 14 are arranged opposite each other. The opposite side of the two clamping blocks 14 is arc-shaped. The bottom of the two clamping blocks 14 is fixedly connected to guide rods 15. The top of the base plate 1 has two guide grooves 16. The two guide grooves 16 are Z-shaped. The guide rods 15 at the bottom of the two clamping blocks 14 slide inside the two guide grooves 16 respectively.
[0027] When using the clamping mechanism, first place the cable in the middle of the moving block 6, then place the crimp terminal on the top of the lower crimp connector 9. After the power is turned on, start the hydraulic rod 5. The output end of the hydraulic rod 5 drives the lower crimp block 4 to move downward. During the downward movement of the lower crimp block 4, it drives the sleeve blocks 17 at both ends to move downward synchronously. The bottom of the sleeve block 17 is rotatably connected to the roller 12 through the connecting rod. As the lower crimp block 4 moves, the roller 12 slides in the inclined push groove 11, thereby pushing the sliding plate 10 to slide along the top of the base plate 1.
[0028] As the sliding plate 10 slides, it drives the moving blocks 6 connected to its two sides to move horizontally on the base plate 1. The movement of the moving blocks 6 drives the two clamping blocks 14 set in the top through groove 13 to move closer to the center. Since the bottom of the clamping block 14 is connected to the guide rod 15, and the guide rod 15 is slidably connected in the guide groove 16 arranged in a Z shape on the top of the base plate 1, the clamping blocks 14 achieve controlled guided movement in the guide groove 16, so that the two clamping blocks 14 gradually move inward and clamp the cable. The opposite surfaces of the clamping blocks 14 have an arc structure, which effectively increases their contact area with the cable and improves clamping stability. After clamping is completed, the cable is pushed to the bottom of the upper pressure connector 8. At this time, the upper pressure connector 8 moves downward under the drive of the lower pressure block 4, contacts the crimping terminal on the top of the lower pressure connector 9 and completes the crimping operation, thereby realizing a stable connection between the terminal and the cable. Through the above structure, a continuous operation process of automatic cable alignment, stable clamping and precise crimping is realized.
[0029] Through the coordinated operation of the sliding plate 10, clamping block 14, guide rod 15, and guide groove 16 in the clamping mechanism, automatic clamping and positioning of the cable is achieved, effectively solving the problem that traditional crimping machines cannot securely hold the cable. The two sliding plates 10 are respectively connected to both sides of the moving block 6 and slide in the inclined push groove 11 with the help of the roller 12, so that the moving block 6 slides on the top of the base plate 1, thereby driving the two clamping blocks 14 in the through groove 13 to move closer to each other to clamp the cable. The bottom of the clamping block 14 is provided with a guide rod 15, which is slidably connected in two Z-shaped guide grooves 16, so that the clamping block 14 can be guided and controlled during the movement, thereby ensuring that the two clamping blocks 14 can be accurately aligned and stably close together. Moreover, the opposite surface of the clamping block 14 is designed with an arc structure, which increases the contact area with the outer wall of the cable, enhances the clamping stability, prevents the cable from shaking or shifting, provides a reliable positioning basis for subsequent crimping operations, and improves crimping accuracy and safety.
[0030] Further, see attached document. Figure 4 As shown, the replacement mechanism includes a slide groove 18 at the bottom of the mounting block 7. Two opposing sliders 19 are slidably connected inside the slide groove 18. Springs 20 are fixedly connected to the side walls of the two sliders 19 and are fixedly connected to the inner wall of the slide groove 18. The bottoms of the two sliders 19 are fixedly connected to opposing locking plates 21. Two locking grooves 22 are opened at the top of the upper pressure connector 8. The outer walls of the two locking plates 21 are respectively adapted to the inner walls of the two locking grooves 22.
[0031] During the replacement process, the upper pressure connector 8 or the lower pressure connector 9 can be quickly replaced by pressing the replacement push plate 23. In specific operation, one end of the replacement push plate 23 has an arc-shaped structure, which matches the arc-shaped surface of one end of the two sliders 19. Under the action of the push plate 23, the two sliders 19 are forced to slide to both sides and compress the spring 20 located between them. When the sliders 19 move away from each other, they drive the locking plate 21 connected to the bottom to leave the inner wall of the locking groove 22 that was originally locked in, so that the upper pressure connector 8 is in the released state. The operator can directly take out the upper pressure connector 8 to realize the replacement of the pressing mold.
[0032] When installing a new upper pressure connector 8, simply align it with the slide groove 18 and apply downward pressure. The top of the upper pressure connector 8 will slide into the slide groove 18. As it continues to press down, the top structure of the locking groove 22 will force the locking plate 21 to shift to both sides and compress the spring 20. After the upper pressure connector 8 is fully inserted into the slide groove 18 and reaches the predetermined installation position, the locking groove 22 and the locking plate 21 are on the same horizontal plane. At this time, the compressed spring 20 releases its elastic force, pushing the locking plate 21 to spring back and insert into the inner wall of the locking groove 22, thereby realizing the automatic locking and fixing of the upper pressure connector 8. This structure not only improves the efficiency of replacing the crimping parts, but also ensures the accurate positioning and stable connection during its installation process.
[0033] By setting up a quick-change structure consisting of a changeable push plate 23, a slider 19, a spring 20, a locking plate 21, and a locking groove 22, convenient disassembly and assembly of the upper pressure connector 8 or the lower pressure connector 9 is achieved, avoiding the cumbersome and time-consuming operation of traditional crimping machines when changing crimping molds. The arc-shaped end of the changeable push plate 23 cooperates with the arc-shaped surface of the slider 19, pushing the slider 19 to compress the spring 20, causing the locking plate 21 to disengage from the locking groove 22, thus achieving rapid mold release. During installation, through the guiding action of the slide groove 18, the locking plate 21 can automatically lock into the locking groove 22 under the restoring force of the spring 20, completing the self-locking position of the mold, improving the replacement efficiency and ease of use of the equipment, and ensuring the safety and connection stability of the replacement process.
[0034] Further, see attached document. Figure 4 As shown, a replacement push plate 23 is slidably connected to the side wall of the mounting block 7. One end of the replacement push plate 23 contacts the opposite side of the two sliders 19. The opposite side of the two sliders 19 and the end of the replacement push plate 23 near the inside of the slide groove 18 are both arc-shaped. Since the side walls of the replacement push plate 23 and the sleeve rod 24 are both arc-shaped, the replacement push plate 23 can easily push the two sliders 19 away from each other, thereby causing the locking plate 21 to release the limiting relationship with the locking groove 22.
[0035] Further, see attached document. Figure 2 As shown, two sleeve rods 24 are fixedly connected between the top of the base plate 1 and the inner wall of the support frame 2. The two sleeve rods 24 are respectively distributed on both sides of the lower pressure block 4. The sleeve blocks 17 on both sides of the lower pressure block 4 are respectively sleeved on the outer walls of the two sleeve rods 24. The arrangement of the sleeve rods 24 increases the stability of the lower pressure block 4 moving up and down.
