Wiring technology of saddle type electric fusion pipe fitting

Abstract

The invention provides a wiring technology of a saddle type electric fusion pipe fitting. The wiring technology comprises the specific steps that two semicircular saddle type pipe fittings of the samespecification are combined to form a cylindrical pipe fitting, and the cylindrical pipe fitting is placed on a wiring machine fixture and is tightened and fixed; a wiring cutting tool is connected with a numerical control machine and is fixed by a limiting device; and a resistance wire penetrates through the wiring cutting tool and is pulled out by a certain distance, the height difference between the edge top end of the wiring cutting tool and the top end of the compressing part is adjusted to obtain the depth of a needed wiring groove, and the resistance wire and the wiring cutting tool arefixed by bolts. A conventional wiring machine and a specially designed wiring cutting tool are adopted, and therefore wiring of the saddle type electric fusion pipe fitting is successfully achieved.The method has the advantages that operation is simple, processing difficulty is little, product quality is stable, and production efficiency is high. The problem of saddle type electric fusion pipe fitting preparation is completely solved. The numerical control machine fixedly provided with the wiring cutting tool is adopted, a wiring track is set, and therefore the required wiring effect can beachieved.

Description

technical field [0001] The invention relates to the field of electric fusion pipe fittings, in particular to a saddle type electric fusion pipe fitting wiring process. Background technique [0002] Saddle-type electrofusion pipe fittings are in the shape of a saddle as a whole, and the inner wall is semicircular, such as figure 1 As shown, its wiring method is different from conventional straight-through electrofusion fittings. The inner wall of conventional straight-through electrofusion pipe fittings is a full circle, and its wiring track is as follows: figure 2 As shown, using the existing wiring machine, the wiring process can be easily realized through the rotation of the fixture and the advancement of the wiring knife transmission device. The wiring of saddle-type electrofusion pipe fittings needs to be wired between the two electrodes on the inner wall of the top, and the trajectory of the wiring knife during the wiring process is completely different from that of ...

Problems solved by technology

[0004] However, this process is relatively complicated and difficult to operate manually. At the same time, when the plastic plate is placed in the cavity of the injection molding machine, the side with the resistance wire needs to be bent outward, which can easily cause the resistance wire to come out of the wire groove. It will not only increase the difficulty of operation, but also cause a decline in production efficiency, and it is difficult to guarantee product quality.

In addition, it is difficult to ensure the roundness of the inner wall of the saddle-shaped pipe fittings prepared by injection molding. If the roundness of the inner wall is not adjusted later, the inner wall of the saddle-shaped electric fusion pipe fitting and the outer wall of the pipe will not fit closely, which will affect the final welding. Effect; if a lathe is used to adjust the roundness of the inner wall of the saddle-shaped electric fusion pipe fitting prepared above, the resistance wire may be cut off by the turning tool
