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 a cutting device of a steel cylinder for producing a prestressed steel cylinder concrete pipe, in particular to a novel anti-deformation device for steel cylinder cutting, andprovides a device capable of effectively preventing cutting deformation of the steel cylinder. The anti-deformation device comprises an inverted L-shaped supporting rod, wherein the supporting rod comprises a vertical rod and a cross rod, a plurality of air cylinders I distributed uniformly are arranged on the radial direction of the cross rod, and balls are arranged at the end heads of piston rods I of the air cylinders I; an air cylinder II is arranged in a groove, the bottom of the air cylinder II is fixed to the bottom of the groove, and a piston rod is fixed at the bottom of an upper rod; and a motor is arranged at the bottom of a lower rod, a connecting line of the motor sequentially penetrates through the lower rod, the upper rod and the cross rod and is connected with cylinder bodies of the air cylinders I. According to the anti-deformation device, manual repair and maintenance is not needed, and the cutting precision is greatly improved; and the anti-deformation device is suitable for steel cylinders with different sizes, and the using range is wide.

Description

technical field [0001] The invention relates to cutting equipment for producing steel cylinders for prestressed steel cylinder concrete pipes, in particular to a novel anti-deformation device for cutting 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 inaccurate cutting. Control, t...
