Preparation facilities of bell and spigot of plastics tubular product

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of production equipment of plastic pipes, in particular to a device for manufacturing a bell and spigot of a plastic pipe.

[ background of the utility model ]

Heavy-calibre plastics add muscle winding bellows and two resistance to compression spiral winding pipes are the novel product of this company's research and development, and it has had the dual characteristic of outer pressure-bearing and interior pressure-bearing concurrently, and combined type structural design has overcome the bottleneck that traditional plastics supplied water tubular product made heavy-calibre tubular product under the circumstances of guaranteeing water delivery pressure, has not only reduced the cost, makes the plastics supply water pipe also can realize higher outside pressure-bearing moreover, realizes burying deeply. Can be used for laying various drainage pipes and conveying water pipes.

Along with the bright phase of tubular product on the market, the service face of this tubular product also expands gradually, plans to replace original plastics thick-walled pipe with this tubular product for municipal water supply and drainage and the gas convulsions of mine and miner's pipeline of fleing. When the pipe ends of the original thick-wall plastic pipe in the water supply field are connected, the butt welding mode is usually adopted because the pipe wall is thick, but the butt welding connection mode is obviously not applicable because the pipe is a thin-wall pipe. The heat shrinkable sleeve is generally used for hot melting connection of large-diameter pipelines with the diameter of more than 1200mm in the drainage field, but the pipes are easy to sink in different ranges under the condition of soft geological soil, so that the joints of the pipes are torn and water leakage occurs.

The company previously developed a Chinese patent No. ZL 201510512265.4 entitled Z-shaped socket electrothermal welding connected large-caliber plastic pipe, and disclosed a Z-shaped socket electrothermal welding connected large-caliber plastic pipe, which comprises a pipe body, a female end and a female end, wherein the female end is arranged at one end of the pipe body, and the female end is arranged at the other end of the pipe body; the socket end comprises a first ring surface and a second ring surface, the diameter of the second ring surface is larger than that of the first ring surface, and a conical transition section is arranged between the first ring surface and the second ring surface; the bell end comprises a third ring surface and a fourth ring surface, the diameter of the fourth ring surface is larger than that of the third ring surface, and a funnel-shaped transition section is arranged between the third ring surface and the fourth ring surface; an electrical heating element mounted at the female end and/or the female end. The joint of the plastic pipe is a Z-shaped plastic pipe, compared with butt fusion and parallel socket electrothermal fusion: the welding surface is not arranged on one cross section, and the welding surface is extended to the x direction and the y direction, so that the welding strength is greatly increased, the pulling performance of a pipeline system is improved, and the ground settlement resistance of the pipeline is enhanced. However, while the welding strength of the welding surface is increased, the structures of the female end and the male end are necessarily complicated, and how to realize reliable connection between the female end and the male end and both ends of the pipe body is also a new research subject.
