Technical Field

[0002] The wire crimping device for electric power construction is an important tool for the power industry to carry out wire crimping during line infrastructure construction and line maintenance.

[0003] In the known prior art, during crimping, workers need to insert the steel core at one end of the two wires into the steel casing, and put the aluminum casing on the outside of the stranded wire of one wire. Two workers each hold a wire so that one end of the two wires overlap and remain horizontal. The hydraulic crimping machine is operated to drive the pressing die (usually hexagonal) on the hydraulic pliers to crimp the steel casing and the aluminum casing in turn, firmly pressing the casing and the wire together to form a connection between the two coils of wire.

[0004] However, a hydraulic crimping machine can only place one type of die at a time, and the sizes of steel casing and aluminum casing are different, so two different dies are needed. Each time after the steel casing is crimped, the steel casing die needs to be replaced with the aluminum casing die, which has low work efficiency. In addition, during the replacement process, the wire needs to be moved significantly, which may easily cause the wire straightness not to meet the standard requirements and the crimping stacking die to be uneven. In addition, adjacent crimped areas need to overlap, and manual movement may easily cause uneven length of the overlapping area, resulting in poor quality of the finished product after crimping.

The first upper pressing die 43 and the first lower pressing die 44 are adapted to the steel sleeve 18, and the second upper pressing die 45 and the second lower pressing die 46 are adapted to the aluminum sleeve 19.

[0043] The hydraulic control device 5 is used to control the use order of the steel sleeve 18 pressing mold and the aluminum sleeve 19 pressing mold. The pressing mold device 4 is placed above the hydraulic control device 5. The hydraulic control device 5 includes: a box body 51, and the box body 51 is provided with a first chamber 52, a second chamber 53, and a third chamber 54. The third chamber 54 is connected to the hydraulic press 11. The third chamber 54 is provided with two liquid inlet holes 57.

[0044] When the inclination angle of the slide groove 58 is 30°, compared with the vertical plane, the inclination degree of the slide groove 58 is small, the distance between the bottom outlet of the slide groove 58 and the floor is large, the liquid is not easy to flow out of the slide groove 58, and the vertical downward component of the slide groove 58 is large, which facilitates the sealing plate 59 to reset to the slide groove 58.

[0046] When crimping the steel sleeve 18 , the bottom of the first lower die 44 is always located above the second lower die 46 . When preparing to crimp the aluminum sleeve 19 , the bottom of the second lower die 46 is always located above the first lower die 44 .

[0047] When the same side of the middle of the steel sleeve 18 or the same side of the middle of the aluminum sleeve 19 is crimped, the length of the overlap of the indentations in two adjacent crimping processes is 5-10 mm.

[0049] When the overlapping length of the indentations of two adjacent crimping processes is 10 mm, the overlapping area is large, the workpiece after crimping is denser, the crimping effect is good, and the two wires are more closely connected.

[0050] In this example, see Figure 1 - Fig.12 When in use, determine the type and diameter of the steel sleeve 18 and the aluminum sleeve 19, find the first die and the second die that match them, put the first lower die 44 and the first upper die 43 into the space between the two wall panels 61 along the first positioning plate 41 in turn, and put the second lower die 46 and the second upper die 45 into the space between the two wall panels 61 along the second positioning plate 42 in turn. The first die includes the first lower die 44 and the first upper die 43, and the second die includes the second lower die 46 and the second upper die 45. The first die and the second die are arranged in parallel, and the central axis of the first die coincides with the first standard line, and the central axis of the second die coincides with the second standard line. First, place the steel sleeve 18 in the pressing groove 432 of the first die, pull the sealing plate 59 so that the sealing plate 59 no longer seals the channel 26 between the third chamber 54 and the first chamber 52, start the hydraulic press 11, and the liquid of the hydraulic press 11 passes through the liquid inlet pipe 12, the liquid inlet head 71, and the third The liquid in the first chamber 52 increases, and the pressure on the floating plate 55 increases. The floating plate 55 moves upward against the shifting plate 63 and the first lower die 44 through the shifting rod 56, and the distance between the first upper die 43 and the first lower die 44 decreases. The pressure on the steel sleeve 18 from the first upper die 43 and the first lower die 44 gradually increases, and the stressed part of the steel sleeve 18 is pressed tightly. After one crimping is completed, the hydraulic press 11 is closed, and the first chamber 5 2 flows back into the hydraulic press 11, and the first upper die 43 and the first lower die 44 move away from each other. When one side of the center position of the steel sleeve 18 is completely crimped, the stepper motor 21 rotates in the opposite direction, and the rotating end of the stepper motor 21 moves the first die and the steel sleeve 18 to the starting position through the screw rod 22. At this time, the central axis of the steel sleeve 18 coincides with the first standard line, and the hydraulic press 11 is started. The stepper motor 21 continues to reverse to complete the crimping of the other side of the steel sleeve 18. After the steel sleeve 18 is crimped, the sealing plate 59 is inserted to seal the first chamber 52 and the third chamber 54, and the other sealing plate 59 is pulled to open the channel 26 of the second chamber 53 and the third chamber 54. The aluminum sleeve 19 is rotated in the direction of the stranded wire 16 so that the central axis of the aluminum sleeve 19 is colinear with the central axis of the steel sleeve 18, and the central axis of the aluminum sleeve 19 coincides with the central axis of the second die, thereby completing the crimping on both sides of the center of the aluminum sleeve 19.

[0054] The fixing device 3 is used to fix and support the two wires to be crimped, and the bottom of the fixing device 3 is connected to the upper surface of the translation device 2.

[0055] When switching from the same side of the middle of the steel sleeve 18 to the other side of the middle of the steel sleeve 18 for crimping, the screw rod 22 brings the first die back to the starting position, and the central axis of the first die at the starting position coincides with the first standard line. When switching from the same side of the middle of the aluminum to the other side of the middle of the steel sleeve 18 for crimping, the screw rod 22 brings the first die back to the starting position, and the central axis of the second die at the starting position coincides with the second standard line. The distance between the first standard line and the second standard line is the same as the distance between the first die and the second die.

[0056] The first pressing die and the second pressing die are positioned respectively by the first standard line and the second standard line to ensure the accuracy of the starting point of the crimping.

[0057] In this example, see Figure 1 - Fig.12 When in use, the aluminum sleeve 19 is screwed in according to the direction of the stranded wire 16 of one conductor, so that the steel sleeve 18 passes through the pressing groove 432 of the first pressing die and the central axis of the steel sleeve 18 coincides with the first standard line, and the steel cores 17 of the two conductors are fully inserted from both ends of the same steel sleeve 18.

The distance that the stepper motor 21 moves each time can be controlled by a relay. When crimping the same side at the center of the steel sleeve 18 and the same side at the center of the aluminum sleeve 19, the length of each crimping and the length of the overlapping area are determined according to the length of the tube and the requirements of the crimping quality, thereby determining the distance that the stepper motor 21 moves each time. With precise control, the quality of the finished product after crimping is high, and the probability of defective rate is reduced. Regardless of the steel sleeve 18 or the aluminum sleeve 19, both sides of the center need to be crimped. Therefore, after the crimping on the same side is completed, the tube to be crimped needs to be returned to the original position and positioned. The first standard line and the second standard line can be used as a basis for judgment to ensure the accuracy of subsequent processes. The entire die is moved by the translation device 2 without dragging the wire, thus avoiding the problem that the wire torque is not released before crimping and the wire clamp tube is twisted during crimping due to the movement of the wire. The modules move at the same distance, and the crimped finished products are of high quality and beautiful. The die device 4 can hold two sets of die molds at the same time, without the need to replace the molds after the first crimping, thus simplifying the crimping procedure, avoiding large-scale movement of the wire, and improving production efficiency. The hydraulic control device 5 is matched with the die, and controls the operation of the two sets of die molds in turn through hydraulics. It has a simple structure and is easy to operate and control. The fixing device 3, the translation device 2, and the die device 4 can be assembled with each other, and occupy a small volume after disassembly, making it easy to carry and use.
