[0022] A guide vertical rod 10 is fixedly connected to the lifting frame 2 , and the lifting frame 2 is slidably connected to the mounting seat 1 via the guide vertical rod 10 .
[0023] The driving member comprises a telescopic cylinder 9 , a cylinder body of the telescopic cylinder 9 is fixedly connected to the mounting seat 1 , and a telescopic end of the telescopic cylinder 9 is fixedly connected to the lifting frame 2 .
[0024] A fixed shaft 5 is fixedly connected to the inverted V-shaped slide rail 31, and an inner ring 51, a middle ring 52 and an outer ring 53 are rotatably connected to the circumferential side surface of the fixed shaft 5 in sequence. A first push rod 511 is fixedly connected to the inner ring 51, a second push rod 521 is fixedly connected to the middle ring 52, and an outer rod 531 is fixedly connected to the outer ring 53; the first push rod 511 and the second push rod 521 are distributed on both sides of the outer rod 531, a first spring 541 is arranged between the first push rod 511 and the outer rod 531, and a second spring 542 is arranged between the second push rod 521 and the outer rod 531; a magnetic ring 55 is fixedly connected to one end of the outer rod 531 away from the fixed shaft 5, and a magnetic block 56 is fixedly connected inside the slip ring 4; a fan-shaped groove 61 is opened on the fixed shaft 5, and a clamping strip 6 is fixedly connected to the outer rod 531, and one end of the clamping strip 6 extends into the fan-shaped groove 61.
[0025] In the above technical scheme, the present invention provides a wire crimping device for electric power construction. By starting the telescopic cylinder 9, under the guiding action of the guide vertical rod 10, the telescopic cylinder 9 drives the lifting frame 2 to move vertically downward through the telescopic end, and the lifting frame 2 drives the rotating shaft 21 inside it to move downward, and the rotating shaft 21 drives the cam 3 and the slip ring 4 to move downward, so that the slip ring 4 slides downward along the first vertical rail 311. Under the limiting action of the first vertical rail 311, the rotating shaft 21, the cam 3 and the slip ring 4 are self-locked (to prevent the rotating shaft 21 from rotating on the lifting frame 2), and the rotating shaft 21 drives the first upper mold 121 on the outside thereof to move vertically downward. The first upper mold 121 performs the first locking of the wire tube on the lower mold 11. After the first upper mold 121 is fitted with the lower mold 11, the telescopic cylinder 9 is controlled to drive the lifting frame 2 and the rotating shaft 21 to move vertically upward, and the rotating shaft 21 drives the cam 3 and the slip ring 4 to move upward, so that the slip ring 4 slides along the first vertical rail 311 to the inverted V-shaped slide rail 31. During the process of the slip ring 4 sliding upward along the first vertical rail 311 and the inverted V-shaped slide rail 31, the slip ring 4 pushes the outer rod 531 to rotate a certain angle around the axis of the fixed shaft 5 through one end of the second push rod 521, so that the outer rod 531 drives the outer card strip 6 to contact the other side wall of the fan-shaped groove 61, and the outer rod 531 drives the outer magnetic ring 55 to rotate around the fixed shaft 5 to the side of the inverted V-shaped slide rail 31 close to the second vertical rail 312 (such as Figure 6As shown in the figure, when the slip ring 4 slides to the top of the inverted V-shaped slide rail 31, the cam 3 drives the rotating shaft 21 to rotate positively by 90 degrees under the limiting action of the inverted V-shaped slide rail 31, and the lifting frame 2 and the rotating shaft 21 are driven to move downward by controlling the telescopic cylinder 9, and the rotating shaft 21 drives the cam 3 and the slip ring 4 to move downward. Under the magnetic force of the magnetic ring 55, the magnetic ring 55 attracts the magnetic block 56 to deviate a certain distance in the direction of the second vertical rail 312, so that the magnetic block 56 drives the slip ring 4 to slide downward along the inverted V-shaped slide rail 31 (a section connected to the second vertical rail 312). Under the limiting action of the inverted V-shaped slide rail 31 (a section connected to the second vertical rail 312), the cam 3 continues to drive the rotating shaft 21 to rotate positively by 90 degrees, passing through the rotating shaft 21. The first upper mold 121 is located on the upper side of the rotating shaft 21 and the second upper mold 122 is located on the lower side of the rotating shaft 21 through two positive rotations of ninety degrees. The rotating shaft 21 continues to drive the cam 3 and the slip ring 4 to move downward, so that the slip ring 4 slides downward along the second vertical rail 312 (self-locking the rotating shaft 21 again). The rotating shaft 21 drives the second upper mold 122 on its outer side to move vertically downward. The second upper mold 122 crimps the wire tube on the lower mold 11 again. Under the effect of the staggered arrangement of the first upper mold 121 and the second upper mold 122, the stacking mold crimping of the wire tube is completed. The stacking mold crimping of the wire tube is completed by the reciprocating lifting and lowering motion of the first upper mold 121 and the second upper mold 122 themselves, thereby reducing the use cost of the overall device.
[0026] like Figure 6-7 As shown in the figure, as one of the embodiments of the present invention, during the process of the slip ring 4 sliding downward along the inverted V-shaped slide rail 31 (a section connected to the second vertical rail 312), under the blocking action of the clamping strip 6 and the fan-shaped groove 61, the outer rod 531 is restricted (preventing the outer rod 531 from rotating downward around the fixed shaft 5), and the slip ring 4 pushes the first push rod 511 to rotate downward around the fixed shaft 5 by a certain angle. After the slip ring 4 is separated from the first push rod 511, under the elastic action of the first spring 541 itself, the first spring 541 pulls the first push rod 511 to reset. During the process of the slip ring 4 sliding upward along the inverted V-shaped slide rail 31 (a section connected to the second vertical rail 312), the slip ring 4 passes The first push rod 511 pushes the outer rod 531 to rotate a certain angle around the fixed shaft 5, so that the magnetic ring 55 is located on the side of the inverted V-shaped slide rail 31 close to the first vertical rail 311. When the slip ring 4 moves to the top of the inverted V-shaped slide rail 31 again, the cam 3 drives the rotating shaft 21 to rotate ninety degrees in the opposite direction. Under the magnetic force of the magnetic ring 55, the slip ring 4 slides downward along the inverted V-shaped slide rail 31 (a section connected to the first vertical rail 311), so that the cam 3 drives the rotating shaft 21 to rotate ninety degrees in the opposite direction again. Through the two reverse rotations of the rotating shaft 21 by ninety degrees, the first upper mold 121 is located on the lower side of the rotating shaft 21 again, and the second upper mold 122 is located on the upper side of the rotating shaft 21 again.
[0027] like Figure 8As shown, in another embodiment provided by the present invention, it is also proposed that the locking assembly includes two symmetrically arranged locking units; each locking unit includes a squeeze block 72, which is slidably arranged on the mounting seat 1, and the bottom of the lifting frame 2 is fixedly connected with a push folding rod 71, the bottom of the push folding rod 71 is an inclined surface, one end of the squeeze block 72 is rotatably connected with a roller 73, and a second elastic member 74 is fixedly connected between the squeeze block 72 and the mounting seat 1; during the descent of the lifting frame 2, the two rollers 73 are squeezed by the inclined surfaces of the two push folding rods 71 to overcome the elastic force of the second elastic member 74 to move the two squeeze blocks 72 together. A rubber block 8 is fixedly connected to the side of the squeeze block 72 close to the wire.
[0028] The folding rod 71 of the lifting frame 2 is pushed upward by the lifting frame 2, so that the pushing folding rod 71 is separated from the roller 73, and the limit of the roller 73 is released. Under the elastic action of the second elastic member 74, the second elastic member 74 pulls the extrusion block 72 to slide to the outside of the mounting base 1, so that the extrusion block 72 drives the rubber block 8 to separate from the wire, so that the staff can take out the crimped wire conveniently.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
