Problems solved by technology

[0003] At present, a coiler is commonly used for coiling. For example, a coiler disclosed in CN204454054U uses a rotating shaft to perform coiling, but it has the following disadvantages: first, it is inconvenient to disassemble the coil; length cannot be adjusted
In the production of coils, the efficiency of coils is low, and the quality of coils is poor

Embodiment 1

[0027] according to figure 1 , figure 2 As shown, a coil machine includes a bracket 1, a rotating shaft 11 is arranged on the bracket 1, and the rotating shaft 11 is sequentially provided with: a fixed disk 2 fixed on the rotating shaft 11, and a utility model composed of two half-discs assembled together. The inner chuck 3 for adjusting the size of the inner ring and the movable disc 4 sleeved on the rotating shaft 11 and slides along the rotating shaft 11 to adjust the distance from the fixed disc 2 .

[0028] Through the rotation of the rotating shaft 11, the steel pipe is wound on the inner chuck 3 to complete the bending, the distance between the movable disk 4 and the fixed disk 2 can be controlled, and the length of the coil pipe and the diameter of the inner chuck 3 can be easily loaded and unloaded.

[0029] The inner chuck 3 comprises a first chuck 31, a second chuck 32 and a diameter adjusting device 33, and the first chuck 31 and the second chuck 32 are hinged ne...

Embodiment 2

[0036] The difference from the above-mentioned embodiment 1 is that, according to image 3 As shown, the outer peripheral surface of the inner chuck 3 and the surface of the fixed plate 2 and the moving plate 4 close to the inner chuck 3 are provided with a buffer layer 6 to protect the steel pipe.

Embodiment 3

[0038] The difference from the first embodiment above is that a slide rail 14 is provided at the bottom of the support 1, which slides axially on the rotating shaft 11 to make the coil more uniform.

Abstract

The invention relates to pipe fitting machining machinery, in particular to a pipe coiling machine. The pipe coiling machine comprises a bracket, wherein a rotating shaft is arranged on the bracket; a fixed disk fixed on the rotating shaft, an inner chuck which consists of two spliced half disks and is used for adjusting the size of an inner circle, and a movable disk which is arranged on the rotating shaft in a sleeving manner and slides along the rotating shaft to adjust a distance between the movable disk and the fixed disk are arranged on the rotating shaft in sequence; the inner chuck comprises a first chuck, a second chuck and a diameter adjustment device; and the position, close to the edge of the inner chuck, of the first chuck is hinged to the second chuck, so that the first chuck can rotate relatively to the second chuck. The pipe coiling machine disclosed by the invention is simple in structure and can be used for manufacturing coil pipes with different lengths; by the adoption of the pipe coiling machine, steel pipes are convenient to load and unload, and the operating speed is increased; and therefore, the production efficiency of the coil pipes is improved.

Description

technical field [0001] The invention relates to a pipe fitting processing machine, in particular to a pipe coil machine. Background technique [0002] Steel pipe is a widely used metal material. Most of the steel pipes on the market are in the form of straight pipes. Compared with straight pipes, the length of coiled pipes can reach more than 1000 meters, which is far longer than that of ordinary straight pipes. During the installation process, the use of ferrules and pipe joints is greatly reduced, which simplifies the entire installation process and reduces the overall cost. At the same time reduce maintenance costs. The use of coils in hydraulic systems can reduce the risk of instrument leakage, especially when installed vertically. Due to the large reduction in the use of ferrules and pipe joints, the integrity of the entire system is improved, thereby improving safety during operation. In the process of sea transportation, the length of steel pipes generally does not ...
