Embodiment 1
[0036] Please also refer to figure 1 and figure 2 , the method for manufacturing the insulating rod provided by the present invention will now be described. The manufacturing method of the insulating rod comprises the following steps:
[0037] S1, mandrel forming, adding insulating material into the extruder 2, extruding the mandrel 1 through the extruder 2, and pulling the mandrel 1 through the traction mechanism 21, so that the mandrel 1 can be continuously pulled out and formed long mandrel 1;
[0038] S2, soaking the fiber felt in the foaming resin, so that the foaming resin fills the inside and both sides of the fiber felt, wherein, the resin content after soaking the foaming resin is 30% to 50%, and then wrapping it on the outside of the mandrel 1 , as fiber felt layer 11;
[0039] S3, covering the fiber dry yarn, wrapping the fiber dry yarn on the outside of the fiber mat according to the layup design to form a mandrel 1, a fiber mat layer 11 and a fiber layup 12 t...
Embodiment 2
[0054] Please also refer to figure 1 and figure 2 , the manufacturing device of the insulating rod provided by the present invention will now be described. The manufacturing device of the insulating rod includes an extruder 2 for extruding the mandrel 1, a fiber mat covering machine 3 for covering the fiber mat on the outside of the mandrel 1, and a fiber mat covering machine 3 for covering the mandrel 1. There is a heating mold 6 for heating and curing the mandrel 1 of the fiber felt; one end of the extruder 2 is provided with a traction mechanism 21 for pulling the mandrel 1; one side of the fiber mat coating machine 3 is provided with The first dipping box 31 for dipping the fiber mat; the fiber mat coating machine 3 and the heating mold 6 are located between the extruder 2 and the traction mechanism 21 .
[0055] Specifically, the extruder 2 and the traction mechanism 21 can be the conventional extruder 2 and the traction mechanism 21 in the prior art, and there is a ce...
Embodiment 3
[0063] Please also refer to figure 1 and figure 2 , the insulating rod provided by the present invention is now described. The insulating rod is formed by using the device disclosed in Example 2 according to the method disclosed in Example 1, which includes a mandrel 1, a fiber mat layer 11 covering the outside of the mandrel 1, and covering the The fiber layup 12 outside the fiber mat layer 11, the mandrel 1, the fiber felt layer 11 and the fiber layup 12 are filled with foaming resin. Specifically, the fiber felt layer 11 is filled with foamed resin, and the foamed resin is heated and foamed during curing and molding, so that the connection between the fiber felt layer 11 and the mandrel 1 can be realized after foaming the foamed resin, and the foamed resin Squeeze the inner mandrel 1 during foaming and expansion to form a good seal, reduce the possibility of moisture ingress, and ensure that the electrical performance of the insulating rod is not affected by wet weather....
