The conductor bar 1 and the insulating shell 2 are molded in the first molding die 5, and are pressed by the pressing device 6 and then molded again in the second molding die 7.

[0030] In this embodiment, as a specific solution, the conductor strip pay-off device 3 includes a pay-off frame 31 and a detachable bobbin 32 arranged on the pay-off frame 31; more specifically, a pair of H-shaped slots 311 can be set on the pay-off frame 31, and both ends of the bobbin 32 are placed in the H-shaped slots 311. When the conductor strip wire roll needs to be placed, one end of the bobbin 32 can be lifted from the H-shaped slot 311.

[0031] In this embodiment, as a specific solution, a limit ring 33 is provided at both ends of the spool 32, and a first adjustment bolt 34 is provided on the limit ring 33; when placing the conductor wire roll, the limit ring 33 at one end is removed, and after placing the conductor wire roll, the limit ring 33 at both ends is adjusted to clamp the conductor wire roll, which can prevent the conductor wire roll from shaking during the unwinding process.

[0032] In this embodiment, as a specific solution, the conductor strip tension control device 9 includes a tension control frame 91 and a traction frame 92 which are sequentially arranged on the insulating shell extrusion device 4, and the tension control frame 91 is provided with a first traction roller 93 and a second traction roller 94, and the front end of the first traction roller 93 is provided with a pair of limiting columns 95, and the front end of the second traction roller 94 is provided with a limiting grid 96; the traction frame 92 is provided with a third traction wheel 97 and a fourth traction wheel 98, and the front end or rear end of the third traction wheel 97 and the fourth traction wheel 98 are also provided with a limiting grid 96 respectively; the limiting columns 95 can limit the multiple conductor strips 1 to prevent the conductor strips 1 from scattering during the pay-off process, and the limiting grid 96 can separate the multiple conductor strips 1 one by one, so that each conductor strip 1 does not interfere with each other.

[0033] In this embodiment, as a specific solution, the pressing device 6 includes a set of side plates 61, a support roller 62 and a pressing roller 63 arranged between the set of side plates 61, and the pressing roller 63 has pressing teeth 64 matching the conductor bar 1; after the combination of the conductor bar 1 and the insulating shell 2 passes through the first forming mold 5, the pressing roller 63 presses the conductor bar 1 in the insulating shell 2, which can improve the tightness of the combination of the conductor bar 1 and the insulating shell 2.

[0034] In this embodiment, as a more specific solution, a second adjusting bolt 65 for adjusting the height of the pressing roller 63 is further provided on the side plate 61; the pressing force can be adjusted by adjusting the height of the pressing roller 63 so that the conductor bar 1 and the insulating shell 2 can be tightly combined.

[0038] The working principle of this utility model is as follows:

[0039] The conductor bar 1 is paid out from the conductor bar pay-off device 3, and is combined with the insulating shell 2 extruded by the insulating shell extrusion device 4 after passing through the conductor bar tension control device 9. After the combination is formed by the first forming die 5, the conductor bar 1 is pressed by the pressing device 6 to make the combination tighter, and then formed by the second forming die 7 and then enters the water cooling device 8 for cooling.

[0040] The utility model combines the extrusion of the insulating shell and the installation of the conductor bar into one, which can improve the processing efficiency and ensure the tightness of the connection between the conductor bar 1 and the insulating shell 2; the conductor bar tension control device 9 is concentrated on the insulating shell extrusion device 4, which has a compact structure and can save workshop space.
