Embodiment 1

[0036] The spiral corrugated pipe in the flexible socket connection process of the spiral corrugated pipe includes a pipe body 1 and a joint 2 , the joint 2 is fixedly connected to the end of the pipe body 1 , and the outer end of the joint 2 is a connecting end 21 . Take a spiral corrugated pipe with joints 2 at both ends as an example, such as figure 1 As shown, the connection end 21 of the joint 2 fixedly connected to one end of the pipe body 1 is a male interface, and the connection end 21 of the joint 2 fixedly connected to the other end of the pipe body 1 is a female interface. When the pipeline of the spiral corrugated pipeline is laid, two adjacent spiral corrugated pipelines are connected through the joints 2 at both ends of the pipe body 1 . In order to fixedly connect the joint 2 to the pipe body 1, the inner end of the joint 2 is a fixed end 22, and the fixed end 22 includes a cylindrical reference part 221 and an insertion part 222, and the outer diameter of the i...

Embodiment 2

[0052] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1. The difference is that in this embodiment, in step c, the outer wall of the pipe body 1 is processed by a turning tool, and the pipe body 1 is rotated during the processing. The knife is fed at a constant speed to remove the crest 11 on the outer surface of the tube body 1 . Through the turning tool processing, only the turning tool needs to be fixed, and the tube body 1 is rotated to make the turning tool move relative to the tube body 1 to cut the material at the wave peak 11 .

Embodiment 3

[0054] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, in step c, a file or sandpaper is used to smooth the wave crest 11 on the outer circular surface of the end of the tube body 1 . The advantage of this method of manually removing the material of the peak 11 is that the production cost is relatively low.

Abstract

The invention provides a helical corrugated pipeline flexible socket type connecting technique and belongs to the technical field of machinery. The invention aims at solving the problems that an existing helical corrugated pipeline is difficult to connect during construction and leakage can be easily caused. In the helical corrugated pipeline flexible socket type connecting technique, a fixed end used for fixing a joint with a pipe body is arranged on a male joint and a female joint respectively, each fixed end comprises a benchmark part and an inserting part which are tubular respectively, the outer diameter of the inserting part is smaller than that of the benchmark part, and the inserting part is inserted into the pipe body by virtue of interference fit. The helical corrugated pipeline flexible socket type connecting technique concretely comprises the following steps: a, loading the pipe body; b, loading the joints; c, processing the outer wall of the pipe body; d, preheating the helical corrugated pipeline; e, coating hot melt glue; f, cooling the helical corrugated pipeline; and g, blanking the helical corrugated pipeline. The technique provided by the invention realizes pre-connection between the pipe body of the helical corrugated pipeline and the joint, so that the helical corrugated pipeline is flexibly connected in a socket manner directly during the construction, the construction difficulty is reduced, and the problem that water seepage appears at the joint is avoided.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a flexible socket connection technology for spiral corrugated pipes. Background technique [0002] The spiral corrugated pipe is a pipe with a spiral corrugated outer surface. Spiral corrugated pipes used in drainage, sewage and other facilities are usually made of non-metallic materials such as plastics and rubber. In order to increase the strength, metal structures are also added to some spiral corrugated pipes, for example, steel belt corrugated pipes, through the composite processing of metal materials and non-metallic materials, the spiral corrugated pipes can be greatly improved without increasing the cost. strength. The spiral corrugated pipe has the advantages of light weight, high pressure resistance, good toughness, fast construction and long service life. [0003] During construction, the connection methods of two adjacent spiral corrugated pipes mainly include: ele...
