Problems solved by technology
[0003] In actual use, it is found that due to the thinner steel cylinder during cutting, it is easy to deform when producing steel cylinders with a caliber above Φ1200, resulting in inaccurate cutting. control, that is to say, the case cannot solve the problem of machining accuracy when the steel cylinder itself is deformed under compression

Abstract
The invention relates to cutting equipment of a steel cylinder for producing a prestressed steel cylinder concrete pipe, in particular to a spiral welding steel cylinder diameter and cutting precisioncontrol device, and provides a spiral welding steel cylinder diameter and cutting precision control device capable of effectively avoiding cutting deformation of a cylinder barrel. The device comprises a conveying rack and a cutting trolley. The conveying rack is used for conveying the spiral welding steel cylinder. A smooth guide rail is arranged at the upper portion of the conveying rack. The cutting trolley is slidably connected to the smooth guide rail. The device further comprises a right-angled U-shaped supporting rod connected to the conveying rack. The end, connected to the conveyingrack, of the supporting rod is connected to the smooth guide rail through a sliding block. No artificial finishing is needed, and the cutting precision is greatly improved.
Description
technical field [0001] The invention relates to cutting equipment for producing steel cylinders for prestressed steel cylinder concrete pipes, in particular to a diameter and cutting precision control device for spiral welded steel cylinders. Background technique [0002] In order to prevent water seepage of the prestressed steel cylinder concrete pipe after installation and use, a thin steel cylinder layer needs to be added to the concrete during the production of the pipe core; the thin steel cylinder layer is generally made by spiral coil welding, and the thickness Generally 1.5mm. In the production process, spiral welding adopts the working mode of continuous coil welding and continuous cutting. At present, this kind of follow-up cutting method is a relatively mature technology. [0003] In actual use, it is found that due to the thinner steel cylinder during cutting, it is easy to deform when producing steel cylinders with a caliber above Φ1200, resulting in inaccurat...
