Problems solved by technology

The traditional connection method is to butt two corrugated pipes, and then bind the two butted corrugated pipes with hot melt tape. It is extremely inconvenient when melting the ribbon
Later, in order to overcome the above-mentioned defects, people connected joints at both ends of the bellows and connected the joints to realize the connection of the bellows. However, the existing joints are all welded by butt welding, and cracks are prone to occur at the butt joints. Phenomenon, thus affecting the life of the entire bellows system, not up to the national use standard, therefore, it has become necessary to provide a joint with a higher connection strength with the bellows

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1 to Figure 4 As shown, the special fixture includes a fixed disk 1 , an axial through hole 101 is opened at the central axis of the fixed disk 1 , and a mounting hole 102 is provided on the fixed disk 1 . A flange plate 2 is installed at the through hole 101 on the rear end surface of the fixed plate 1 . A guide column 3 extending toward the rear end of the fixed plate is fixed on the flange plate 2 by bolts, and the guide column 3 is a hollow structure. A guide shaft 4 passing through the through hole 101 is fixed on the guide column 3 , and a thread 401 is provided at the front end of the guide shaft 4 . The guide shaft 4 is covered with a tapered sleeve 5, the front end of the tapered sleeve 5 is connected with a cylindrical sleeve 6, the tapered sleeve 5 and the cylindrical sleeve 6 are integrally formed,...

Abstract

The invention discloses a production method of a corrugated pipe joint, which comprises the following steps of: (1) mounting a special fixture on a chuck of a lathe; (2) mounting a corrugated pipe joint blank on the special fixture; (3) starting the lathe, and turning the outside diameter of one end of the corrugated pipe joint blank; (4) stopping the lathe, turning around and mounting the corrugated pipe joint blank processed in the step (3) on the special fixture; (5) starting the lathe, and turning a helical step on the outside diameter on the other end of the corrugated pipe joint blank; and (6) stopping the lathe and detaching the threaded pipe joined processed in the step (5) to finish the one-time production of the corrugated pipe joint. The production method is suitable to be usedfor producing corrugated pipe joint blanks with different pipe diameters, and the corrugated pipe joint blank is stably mounted in the production process, so that the production safety is good.

Description

technical field [0001] The invention relates to a production method of a corrugated pipe joint, especially a municipal corrugated pipe joint. Background technique [0002] Bellows are widely used because of their ability to withstand large radial loads, light weight, and high manufacturing efficiency. In the use of the existing corrugated pipes, due to various factors such as transportation and terrain, it is necessary to connect the corrugated pipes on site. The traditional connection method is to butt two corrugated pipes, and then bind the two butted corrugated pipes with hot melt tape. It is extremely inconvenient when melting the ribbon. Later, in order to overcome the above-mentioned defects, people connected joints at both ends of the bellows and connected the joints to realize the connection of the bellows. However, the existing joints are all welded by butt welding, and cracks are prone to occur at the butt joints. Phenomenon, thereby affecting the service life o...
