Description

TECHNICAL FIELD

[0001] The integrated wire embedding cutter disc for processing reinforced polyethylene electrofusion pipe fittings relates to an integrated wire embedding cutter disc used in the processing of reinforced polyethylene electrofusion pipe fittings, belonging to the technical field of water supply and drainage, and particularly relates to an embedded wire cutter disc which, in the process of slot cutting and extrusion embedding, rotates and conveys resistance wires through resistance wire winding rods, reduces resistance in the resistance wire conveying process through guide wheels and wear-resistant wheels, has a short resistance wire conveying distance and small friction resistance, and is not easy to fall out of the slot or deviate during embedding. BACKGROUND

[0002] The pipe is usually made of PE material, which has the advantage of strong corrosion resistance, but the rigidity and strength are always important problems faced by researchers. Currently, the common solution to the material pipe is to start from material research and development, which has a long research and development cycle and high comprehensive cost.

[0003] In order to improve the above problems, the applicant proposes a Chinese utility model patent application for steel wire wrapped pipe with the patent name CN210153353U. The wrapped pipe improves the structure of the pipe on the physical level, which includes an inner layer pipe first hot-melt extruded, an outer layer pipe second hot-melt extruded, and a steel wire layer sandwiched between the inner layer pipe and the outer layer pipe. The rigidity and strength of the pipe body are enhanced by internal reinforcing ribs, so that the pipe body is not easy to deform along the axial direction, greatly reduces the deflection of the pipe body along the axial direction, and has better shear resistance.

[0004] In actual use, multiple steel wire wrapped pipes are connected end to end and laid in a trench to meet the drainage distance requirement. However, the steel wire wrapped pipe cannot be directly hot-melt butt welded due to the steel wire wrapped in the pipe wall, so it needs to be connected at the end by polyethylene flaring hot-melt connection, polyethylene electrofusion pipe fitting connection, or rubber sealing ring connection. However, the above connection methods use only polyethylene material at the connection, which has low pressure-bearing capacity. The pressure-bearing capacity of the connected steel wire wrapped pipe at the connection is lower than that of the steel wire wrapped pipe itself. If the steel wire wrapped pipe itself is used for drainage, the connection may be easily broken by excessive pressure. If the connection is used for drainage, it may cause waste of the drainage capacity of the long steel wire wrapped pipe.

[0005] In order to improve the above problems, the applicant has filed another patent application entitled "A reinforced polyethylene electrofusion pipe fitting and a processing method thereof", which forms a reinforced polyethylene electrofusion pipe fitting by cutting a spiral groove on the inner wall of the reinforced polyethylene pipe section with a cutter, embedding a resistance wire in the groove, and embedding the resistance wire by extrusion. The reinforced polyethylene electrofusion pipe fitting can effectively improve the pressure capacity of the connection and make it consistent with the steel wire wrapped pipe. However, the processing method of cutting and embedding the resistance wire has the problem that the resistance wire is transported to the cutter through a metal hose, the transportation distance is long, the resistance wire is subjected to a large frictional resistance, and the resistance wire is easily pulled out of the groove or deviated during embedding, resulting in wire running phenomenon and affecting the quality of the electrofusion pipe fitting.
