Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0025] The purpose of the present invention is to provide a wire connecting tube threading and crimping integrated machine to solve the problems existing in the above-mentioned prior art. After the crimping operation, the connecting tube and the pressing die can be separated to avoid damage to the connecting tube.
[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] The wire connection and pipe threading technology known to the inventor is mainly operated manually, with 3-5 operators on the construction site. When connecting the wires, the wires on one side need to be inserted into the aluminum tube first, and then the steel core is broken up for double-end overlap and plug-in. It is difficult to ensure the straightness of the aluminum tube during on-site manual operation. When connecting the steel pipe, the steel pipe has a small diameter, the plug-in resistance is large, and the docking is difficult. There is no effective mechanized pipe threading and wire entry technical solution and on-site operation.
[0028] At present, the wire splicing crimping process is a system composed of special hydraulic crimping equipment such as a pump station, crimping pliers, and a die. The pump station provides high-pressure oil, and the crimping pliers are pushed by a hydraulic cylinder. The die can be clamped in the crimping pliers. When working, the crimped parts are placed in the die in the crimping pliers, and the bulky crimping pliers are manually moved to the required suitable crimping position. The hydraulic pump station is manually operated to provide hydraulic high-pressure oil to push the hydraulic pliers to work, thereby realizing the die crimping the splicing pipe, crimping section by section, and completing the crimping of the splicing pipe. The labor intensity is high, and quality control is difficult. Moreover, pipe threading and crimping need to be performed separately, and it is impossible to achieve integration of pipe threading and crimping. Based on this, the present invention provides a wire splicing pipe threading and crimping all-in-one machine, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, it includes a base frame 3, a demoulding movable frame 5, and a wire movable frame 6.

The servo electric cylinder 1 has the advantages of small size, large thrust, and easy control. The control displacement accuracy is 0.05mm, and the matching displacement sensor can reach 0.02mm, and the thrust is precisely controlled, and the thrust accuracy is 5%. The pressure sensor is added to achieve 1% precision control speed, high and low speed performance, and the thrust can be maintained at any position.
[0030] In order to realize the automatic pipe threading operation of the wire, the present embodiment is provided with a slider at the bottom of the wire moving frame 6, and a slide rail is provided on the frame. The slider is slidably arranged on the slide rail. The frame is provided with a horizontal driving device 9. The horizontal driving device 9 can drive the wire moving frame 6 to move horizontally. When the pipe threading operation is performed, the wire fastener 7 fastens and fixes the wire, and then the horizontal driving device 9 drives the wire to move horizontally until one end of the wire is inserted into the connecting pipe at the die 14. In one embodiment, the horizontal driving device 9 adopts a gear rack structure, including a rack fixed on the frame, the rack is meshed and connected with a gear, the gear is fixed on the output shaft of the driving motor 8, the driving motor 8 is fixedly connected to one side of the wire moving frame 6, the driving motor 8 is connected to an external power supply through the drag chain 15, the power supply is started, the driving motor 8 drives the gear to rotate, so that the gear drives the driving motor 8 to move horizontally along the rack, and since the driving motor 8 is fixed on the wire moving frame 6, the wire moving frame 6 moves synchronously with the driving motor 8.

The die 14 of this embodiment includes an upper die 20 and a lower die 21 arranged symmetrically up and down, and the upper die 20 is fixed on the upper part of the crimping pliers, and the crimping pliers can drive the lower die to move up and down, so as to realize the crimping of the butt joint pipe. In order to better realize the integrated design of crimping and pipe threading, the present embodiment also provides a connecting pipe fastener 13, which can be detachably arranged between the upper die 20 and the lower die 21, and the upper die 20 and the lower die 21 can fix and clamp the connecting pipe fastener 13. The connecting pipe fastener 13 is an aluminum connecting pipe fastener or a steel connecting pipe fastener, which can respectively fasten the aluminum connecting pipe or the steel connecting pipe, so as to cooperate with the wire fastener 7 to realize the pipe threading operation. The setting of the connecting pipe fastener 13 avoids the problem of being unable to thread the pipe smoothly due to the die 14 crimping the connecting pipe during the pipe threading operation. After the pipe threading is completed, the connecting pipe fastener 13 is removed, and the die 14 can be used to crimp the connecting pipe on the wire.
[0032] When the present invention is working, the driving motor 8 drives the gear to move along the rack, and then drives the conductor moving frame 6 to move to complete the work of threading the connecting tube; the servo electric cylinder 1 will move up and down according to the working state, and drive the demoulding moving frame 5 to move up and down to adjust the center position of the conductor. When threading the connecting tube, the servo electric cylinder 1 moves to keep the center of the conductor aligned with the center of the connecting tube. When crimping, the servo electric cylinder 1 will drive the demoulding moving frame 5 to move upward with the lower die 21 of the crimping pliers to ensure that the center of the conductor coincides with the mold line when the mold is closed. The motor in the electric control box 10 drives the screw to drive the crimping pliers to move left and right to complete the crimping work. When demolding, the servo electric cylinder will drive the demoulding moving frame 5 to move downward with the lower die 21 to ensure that the connecting tube and the upper and lower dies 21 are separated.
