Description

Technical Field

[0001] The present invention relates to an integrated wire embedding cutter disc for processing reinforced polyethylene electric fusion pipe fittings, which belongs to the field of water supply and drainage technology, and in particular to a wire embedding cutter disc in which a resistance wire winding rod rotates to transport the resistance wire during the process of cutting grooves, extruding and embedding wires, and a guide wheel and an anti-wear wheel are used to reduce the resistance during the transmission of the resistance wire. The resistance wire has a short transmission distance, is subjected to small friction resistance, and is not easy to fall off or deviate from the groove under force during embedding. The wire embedding cutter disc integrates the functions of inner circle turning, groove cutting, wire embedding and wire feeding, and has high processing efficiency. Background Art

[0002] The pipe is usually made of PE material, which has the advantage of strong corrosion resistance, but its rigidity and strength are always important issues faced by R&D personnel. At present, the usual way to solve the material problem of the pipe is to start from material research and development, which has a long R&D cycle and high comprehensive cost.

[0003] In order to improve the above problems, the applicant filed a Chinese utility model patent application with publication number CN210153353U and patent name "Wire Wrapped Tube". The wrapped tube improves the structure of the row tube based on the physical level, including: an inner tube extruded by the first hot melt extrusion, an outer tube extruded by the second hot melt extrusion, and a steel wire layer sandwiched between the inner tube and the outer tube. The rigidity and strength of the tube body are enhanced by internal reinforcement ribs, so that the tube body is not easy to deform along the axial direction, greatly reducing the deflection of the tube body along the axial direction, and also has better shear resistance.

[0004] In actual use of pipes, multiple wire wrapped pipes need to be laid end to end in a groove to meet the drainage distance requirements. However, wire wrapped pipes cannot be directly hot-melt welded because of the steel wire wrapped inside the pipe wall. Therefore, polyethylene expansion hot-melt connection, polyethylene electric fusion pipe connection or rubber sealing ring connection are required for end to end connection. However, in the above connection methods, the connection part is made of pure polyethylene material and has a low pressure bearing capacity. The pressure bearing capacity of the connected wire wrapped pipe is lower than the pressure bearing capacity of the wire wrapped pipe itself. If the pressure bearing capacity of the wire wrapped pipe itself is used for water supply and drainage, it is easy to cause the connection to be subjected to excessive pressure and rupture. If the pressure bearing capacity of the connection is used for water supply and drainage, it will cause a waste of drainage capacity of a large section of wire wrapped pipe.

[0005] In order to improve the above problems, the applicant filed another Chinese invention patent application entitled "A Reinforced Polyethylene Electric Fusion Pipe Fitting and Its Processing Method", which uses a cutting knife to open a spiral groove on the inner wall of the reinforced polyethylene pipe section, and at the same time bury the resistance wire in the groove, and bury the resistance wire by extrusion to form a reinforced polyethylene electric fusion pipe fitting. Connecting multiple steel wire winding pipes through the reinforced polyethylene electric fusion pipe fitting can effectively improve the pressure bearing capacity of the connection and make it consistent with the steel wire winding pipe. However, in the processing method of cutting grooves and burying resistance wires, during the wire burying process, the resistance wire is transported to the cutting knife through a metal hose. The transportation distance is long, and the friction resistance of the resistance wire is large. It is easy to fall off or deviate from the groove due to tension, resulting in wire running, which affects the quality of the electric fusion pipe fitting. Summary of the invention

[0006] In order to improve the above situation, the present invention provides an integrated wire embedding cutter disc for processing reinforced polyethylene electric fusion pipe fittings, which provides a wire embedding cutter disc that winds the resistance wire on the resistance wire winding rod, and when the cutting knife cooperates with the extrusion block to embed the resistance wire into the inner wall of the reinforced polyethylene pipe section, the resistance wire winding rod rotates to transport the resistance wire, and at the same time reduces the resistance during the transmission of the resistance wire through the guide wheel and the anti-wear wheel. The resistance wire has a short transmission distance and is subject to small friction resistance, and is not easy to fall off or deviate from the cutting groove under force during embedding.
