Embodiment 1

[0024] 1) Steel pipe forming:

[0025] Cutting: select pipes of appropriate specifications for processing, inspect the raw materials before processing, and cut the pipes according to the required length by the cutting machine to ensure the flatness of the cross section;

[0026] Bending: The pipe fittings to be bent are processed by the pipe bender, and bent into the bend pipes of the required specifications, so as to avoid scratches on the pipe fittings during bending;

[0027] Punching: Put the truncated and bent pipe fittings on the punching machine to punch holes, including socket holes and bolt holes, to facilitate subsequent assembly and connection;

[0028] 2) Polishing treatment: firstly polish the surface and section of the pipe fittings to remove burrs on the surface and section of the pipe fittings, and then perform shot blasting treatment on the surface of the pipe fittings to remove scum and rust on the surface of the pipe fittings. During the shot blasting treatm...

Abstract

The invention discloses a novel guardrail surface on-line treatment production technology. The production technology comprises the following step that steel pipe forming is carried out, wherein pipeswith appropriate specifications are selected for machining, raw materials are detected before machining, the pipes are cut off according to the required length by using a cutting-off machine, and thesections of the pipes are guaranteed to be flat. According to the novel guardrail surface on-line treatment production technology, the technological process is simple, firstly, steel pipe forming machining is carried out, the steel pipes are formed through cutting-off, bending and punching so that the pipes can be conveniently assembled into a guardrail in the sequent process, then polishing and grinding are carried out so as to removal floating slag and burrs on the surfaces of the pipes, then the surface treatment of the pipes is carried out through water washing and mixed washing so that stains on the surfaces of the pipes can be completely removed, then subsequent coating can be conveniently carried out on the pipes, the pipes and the guardrail can be isolated from air during use through coating, oxidation is avoided, the subsequent maintenance workload is reduced, then passivation and wax permeation treatment are carried out in the sequent processes, then the rigidity and the glossiness of the guardrail are guaranteed, and the product quality is improved.
