Description
Technical field
The present invention relates to a kind of production method of electric fusion joint, more particularly to a kind of producer of polyethylene electric-melting connector
Method.
Background technology
Polyethylene electric-melting connector is used for the connection between Gas Pipe Gas Pipe and Gas Pipe Gas Pipe at present, it includes connection
Pipe, heating wire, binding post and observation column；The production method of present polyethylene electric-melting connector is, as shown in Figure 1, first by heating wire 1
Appearance coats a round polyethylene layer 2, then will be coated with the heating wire 1 of round polyethylene layer 2 around the home as shown in Figure 2 and Figure 3
Onto the core rod 3 of production polyethylene electric-melting connector, make the heating wire 1 in finished product electric fusion joint both ends heating welding position close
It is adjacent, then the core rod 3 is placed into the mould 4 of production polyethylene electric-melting connector and is put into binding post 5 in mould 4, finally
Polyethylene material is injected into mould 4 by the injection hole 6 of mould 4 polyethylene electric-melting connector is made, due to 1 appearance of heating wire
A round polyethylene layer 2 is coated, by the heating wire 1 around the home to rear adjacent electric heating on the core rod 3 of production polyethylene electric-melting connector
A gap 7 is had between silk 1 and core rod 3, can be right when injecting polyethylene material since injection hole 6 is the middle part against core rod 3
The heating wire 1 at the middle part of core rod 3 produces impact, due to having a gap 7 between the adjacent heating wire 1 and core rod 3 at the middle part of core rod 3
Presence, be subject to inject polyethylene material impact under, heating wire 1 is easily subject to upward thrust from gap 7 at this so that
Spacing in manufactured finished product electric fusion joint between the heating wire of the position is inconsistent, and thus the finished product electric fusion joint was using
Heating-up temperature in journey at the position can not achieve uniformity, influence stability of the finished product electric fusion joint in electric fusion welding,
The final welding quality for influencing electric fusion joint.
The content of the invention
For disadvantage mentioned above, it is an object of the invention to provide one kind to make heating wire in polyethylene electric-melting connector production process
In do not shift and ensure the stability that finished product electric fusion joint uses polyethylene electric-melting connector production method.
The technology contents of the present invention are that a kind of production method of polyethylene electric-melting connector, it includes the following steps：
（1）, first by heating wire appearance coat a square polyethylene layer, be equipped with a groove in the side of square polyethylene layer, with
The opposite side of the corresponding square polyethylene layer of groove is equipped with a convex block；
（2）, by the above-mentioned heating wire for being coated with square polyethylene layer around the home to production polyethylene electric-melting connector core rod on, make place
Heating wire in finished product electric fusion joint both ends heating welding position is closely adjacent, wherein the square polyethylene layer of adjacent heating wire
Groove be mutually twisted with convex block；
（3）, by step（2）In be wound with heating wire core rod be placed into production polyethylene electric-melting connector mould in and in a mold
Binding post is put into, polyethylene material is then injected into mould by the injection hole of mould and polyethylene electric-melting connector is made.
The possessed compared with prior art advantage of the present invention is：Heating wire appearance is coated a square polyethylene by the present invention
Layer, so its around the home to produce polyethylene electric-melting connector core rod on after, will not have gap between adjacent heating wire and core rod
Produce, simultaneously because the groove of the square polyethylene layer of adjacent heating wire can be mutually twisted with convex block, can be further ensured that mould
Adjacent heating wire is subject to that under the impact of injection polyethylene material movement will not be produced in the middle part of core, so as to ensure that finished product electric-fusion
Stability of the head in electric fusion welding, so as to ensure that the stability of welding quality.

Embodiment
A kind of production method of polyethylene electric-melting connector, it includes the following steps：
（1）, as shown in figure 4, first by 8 appearance of heating wire cladding, one square polyethylene layer 9, the one of square polyethylene layer 9
Side is equipped with a groove 9.1, and a convex block 9.2 is equipped with the opposite side of square polyethylene layer 9 corresponding with groove 9.1；
（2）, as shown in figs. 5 and 6, by the above-mentioned heating wire 8 for being coated with square polyethylene layer 9 around the home arrive production polyethylene electric-melting
On the core rod 10 of connector, make the heating wire 8 in finished product electric fusion joint both ends heating welding position closely adjacent, wherein adjacent
The groove 9.1 of the square polyethylene layer of heating wire 8 is mutually twisted with convex block 9.2；
（3）, by step（2）In be wound with heating wire 8 core rod 10 be placed into production polyethylene electric-melting connector mould 11 in and
Binding post 12 is put into mould 11, then injected by the injection hole 13 of mould 11 into mould 11 polyethylene material i.e. be made it is poly-
Ethene electric fusion joint.
