Description

{Folded Tube Manufacturing Apparatus}

The present invention relates to a corrugated pipe manufacturing apparatus, and more particularly to a corrugated pipe manufacturing apparatus in which a corrugation is formed by supplying hydraulic pressure to a gas pipe.

The corrugated pipe is generally used for supplying gas and fluid to the places where the gas and fluid are needed as the main material, such as metal material, polyvinyl chloride (PVC) material, rubber material, etc., and is widely used for drainage and water supply. Because it is widened to prevent leakage, it is installed in two drainage facilities with different discharge capacity or different elasticity, so that it is mainly used for exposure piping.

Although there are various shapes of the corrugated tube, the corrugated tube having the corrugated corrugation of the "d" type has a problem in that the flow portion of the fluid is not smooth and the foreign material is caught in the corrugated portion during long- A spiral-shaped corrugated tube which can smoothly discharge the fluid, which comes into contact with the corrugated tube, along the spiral groove to improve the drainage function is mainly used.

Korean Registered Utility Model No. 20-0309809 (Mar. 26, 2003) is a rubber material which has excellent elasticity and watertightness but also maintains fluid flow smoothly by improving durability against elongation fatigue and is easy to install and repair. Described in relation to the corrugated tube is a body portion having rubber as a main component and having a corrugated tube shape; And a core portion integrally formed with the main body portion at both ends of the main body portion and having a cylindrical shape, a main portion including a steel wire and a fibrous material, and a core portion inserted into the main body portion and the connection portion while being spirally wound. According to the described technology, while improving the durability and resilience against the elongation fatigue while taking advantage of the rubber material having excellent elasticity and watertightness, it is easy to install and repair work in the drain pipe because the connection and detachment are easy and the connection is made robust.

Korean Registered Patent No. 10-0420675 (Feb. 18, 2004) has a function to reduce the fluid resistance of the spiral corrugated tube and to withstand the warpage, and at the same time, it can also be used for fastening the annular corrugated pipe or the straight pipe. A method of forming a corrugated pipe for piping that can be easily, quickly, and at low cost. According to the disclosed technology, in constructing the pipe for transporting fluids, the annular wrinkle portion and the spiral wrinkle portion are simultaneously formed on one pipe pipe to cut at least one protruded cut portion of the annular wrinkle portion, Thereby facilitating fastening.

The conventional wrinkle pipe manufacturing apparatus as described above has a problem that some cracks may be generated in the process of repeatedly bending the pipe due to unevenness in thickness along the corrugation of the pipe by using the compression bonding method.

The conventional wrinkle pipe manufacturing apparatus has a disadvantage that a thin pipe can be easily torn or twisted when a thin pipe is squeezed due to the use of the compression molding forming method and the thick pipe must be used after being compressed.
