Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power installation, in particular to a wire nose pressing device. Background Art
[0002] When connecting cables to electrical cabinets or equipment, it is necessary to install a wire lug at the end of the wire core to facilitate the connection. In the prior art, hydraulic crimping pliers are generally used to install wire lugs. Two pressure blocks are placed in the clamp head of the hydraulic crimping pliers. When the two pressure blocks are put together, a regular hexagonal pressure shape is formed in the middle, thereby crimping the wire lug to the outside of the wire core. Figure 6 As shown, since the two pressing blocks are gradually brought together from both sides, when the two pressing blocks are about to be brought together, a part of the wire nose will emerge from both sides of the pressing. When the two pressing blocks continue to approach, the protruding part will be squeezed into a fin 1. Sometimes the fin 1 will be much higher than the surface of the wire nose, which is very unsightly. Moreover, when the fin 1 is too large, it will affect the connection between the cable and the electrical control cabinet or equipment. Utility Model Content

DETAILED DESCRIPTION
[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Specific implementation method: Figure 1-5As shown, a wire nose pressing device includes a frame 2, an upper die 5 is provided on the top of the frame 2, a lower die 4 slidably connected to the frame 2 is provided directly below the upper die 5, a jack 3 capable of driving the lower die 4 to rise is provided in the frame 2, a first plane 522 is provided on the upper die 5, a first slider 53 and a third slider 56 are also slidably connected to the upper die 5, the first slider 53 is slidably connected to the eighth plane 564 on the third slider 56, and the angle between the eighth plane 564 and the first plane 522 is 120°, A sixth plane 562 is provided on one side of the third slider 56, and the sixth plane 562 is parallel to the first plane 522. A second plane 531 is provided on one side of the first slider 53, and the angle between the second plane 531 and the first plane 522 is 120°. The lower mold 4 and the upper mold 5 have the same structure and are oriented in opposite directions in height and width, that is, the lower mold 4 faces upward and the upper mold 5 faces downward. If the third slider 56 on the upper mold 5 is on the left side of the first slider 53, then the third slider 56 on the lower mold 4 is on the right side of the first slider 53. When the lower mold 4 rises, the sixth flat surface 562 on it aligns with the first flat surface 522 on the upper mold 5. Simultaneously, the sixth flat surface 562 on the upper mold 5 also aligns with the first flat surface 522 on the lower mold 4. At this point, the two first flat surfaces 522, the two second flat surfaces 531, and the two eighth flat surfaces 564 enclose a regular hexagon on the vertical plane. The side length of the regular hexagon decreases as the lower mold 4 continues to rise, thereby pressing the wire nose against the wire core. When the regular hexagon is at its maximum side length, the diameter of the wire nose is smaller than the diameter of the inscribed circle of the regular hexagon, ensuring that the regular hexagon remains closed after compression begins, thus preventing the formation of flying wings 1. The assembly also includes a reset mechanism that resets the first and third sliders 53, 56. After the lower mold 4 descends, the first and third sliders 53, 56 are reset by the reset mechanism to allow for the next compression operation. A limit mechanism is also included to prevent the third slider 56 from falling. The eighth plane 564 is parallel to the moving direction of the lower mold 4 .
[0018] In this embodiment, the upper mold 5 includes a bottom plate 51, a forming plate 52 and a guide plate 54 are provided on the bottom plate 51, and a second slider 55 is slidably connected between the two. The second slider 55 is preferably in the shape of a rectangular parallelepiped, and a first spring is provided between the second slider 55 and the bottom plate 51. The end of the second slider 55 away from the first spring is slidably connected to the seventh plane 563 on the third slider 56, and the seventh plane 563 is perpendicular to the eighth plane 564. A fourth plane 541 is provided on the side of the guide plate 54 close to the forming plate 52, and the fifth plane 561 on the third slider 56 is connected to the fourth plane The first flat surface 522 is slidably connected to the guide plate 54 on the forming plate 52. The angle between the fifth flat surface 561 and the seventh flat surface 563 is 120°. The first flat surface 522 is provided on the side of the forming plate 52 close to the guide plate 54. The forming plate 52 is provided with a guide groove 521. The first slider 53 is slidably connected to the guide groove 521, with a second spring disposed therebetween. A third flat surface 532 is provided on the end of the first slider 53 remote from the second spring. The third flat surface 532 is slidably connected to the eighth flat surface 564 on the third slider 56. The sixth flat surface 562 is provided on the side of the third slider 56 remote from the base plate 51. When the lower mold 4 falls, the second spring can reset the first slider 53. The first spring and the second slider 55, as well as the second spring and the first slider 53, can reset the third slider 56.
[0019] In this embodiment, clamping plates 57 are provided on both sides of the forming plate 52 and the guide plate 54. The first slider 53, the second slider 55 and the third slider 56 are located between the two clamping plates 57. Both sides of the three sliders are respectively in contact with the two clamping plates 57 and can slide relative to each other. The clamping plates 57 can prevent the three sliders from falling from both sides.
[0020] In this embodiment, limiting columns 565 are provided on both sides of the third slider 56, and a limiting hole 571 is provided on the clamping plate 57. The limiting columns 565 are located in the limiting holes 571 and can move in the limiting holes 571. When the limiting columns 565 contact the side of the limiting hole 571 away from the bottom plate 51, they cannot continue to move so that the third slider 56 will not fall. This structure forms a limiting device, which can prevent the third slider 56 from falling.
[0021] Working principle: After the wire nose is put on the end of the wire core, it is placed in the groove formed by the first plane 522, the second plane 531 and the eighth plane 564 on the lower mold 4, and then the jack 3 is operated to make the lower mold 4 rise. When the lower mold 4 and the upper mold 5 are in Figure 4When the lower mold 4 is in the middle state, the two first planes 522, the two second planes 531 and the two eighth planes 564 surround a regular hexagon on the vertical plane. At this time, the wire nose is in the state of being inserted into the regular hexagon. The lower mold 4 continues to rise, and the third slide block 56 on the upper mold 5 slides obliquely upward along the fourth plane 541. The first slide block 53 on the upper mold 5 slides obliquely upward along the guide groove 521. The third slide block 56 on the lower mold 4 slides obliquely downward along the fourth plane 541 and relative to the fourth plane 541 (actually rising relative to the frame 2 and the lower mold 4). The first slider 53 on the lower die 4 slides along the guide groove 521 and obliquely downward relative to the guide groove 521 (actually it rises relative to the frame 2 and moves in the direction of the second spring on the lower die 4), so that the side length of the regular hexagon is shortened. When the six sides of the regular hexagon are in contact with the outer diameter of the wire nose, the lower die 4 continues to rise, and the wire nose can be pressed tightly against the wire core without flying fins 1. When the diameter of the wire nose is within a certain range, there is no need to replace pressure blocks of different specifications to adapt to wire noses of different diameters like hydraulic crimping pliers.
[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
