Problems solved by technology

[0002] The guardrail is mainly used for the protection and isolation of the site, equipment, etc. It is a common isolation mechanism with multiple uses and is widely used. The guardrail is generally made by processing and assembling steel pipes. When the guardrail is processed, it needs Forming, surface treatment and coating, the existing guardrail processing process is complicated, the processing cycle is long, and the performance of the guardrail after treatment needs to be improved, and a lot of cleaning and maintenance work is required during use, and the guardrail will be easily affected if it is not handled properly. appearance and service life

Embodiment 1

[0024] 1) Steel pipe forming:

[0025] Truncating: Select pipes of suitable specifications for processing, and inspect the raw materials before processing, and cut off the pipes according to the required length by the cutting machine to ensure the smoothness of the section;

[0026] Bending: Process the pipe that needs to be bent by a pipe bender, and bend it into a pipe of the required specification to avoid scratches on the pipe during bending;

[0027] Punching: Place the cut and bent pipe fittings on a punching machine for punching, including insertion holes and bolt holes, which are convenient for subsequent assembly and connection;

[0028] 2) Grinding treatment: first grind the surface and section of the pipe fitting to remove the burrs on the surface and section of the pipe fitting, and then carry out shot blasting treatment on the surface of the pipe fitting to remove the scum and rust on the surface of the pipe fitting. For shot blasting, choose 25 mesh steel shot o...

Abstract

The invention discloses a production process for on-line treatment of the surface of a new type of guardrail, which comprises the following steps: forming a steel pipe: selecting a pipe of a suitable specification for processing, testing raw materials before processing, and cutting the pipe according to the required length by a cutting machine , to ensure the flatness of the section. The production process of the new type of guardrail surface on-line treatment is simple. The process is simple. First, the steel pipe is formed, and the steel pipe is formed by cutting, bending and punching, which is convenient for subsequent assembly into a guardrail. Grinding to remove the scum and burrs on the surface of the pipe fittings, and then the surface treatment of the pipe fittings is carried out through water washing and mixed washing to completely remove the stains on the surface of the pipe fittings, which is convenient for the subsequent coating of the pipe fittings. Avoid oxidation, reduce the workload of subsequent maintenance, and then carry out passivation and wax penetration treatment to ensure the rigidity and gloss of the guardrail and improve the quality of the product.

Description

technical field [0001] The invention relates to the field of production of guardrails, in particular to a production process for on-line treatment of the surface of a novel guardrail. Background technique [0002] The guardrail is mainly used for the protection and isolation of the site, equipment, etc. It is a common isolation mechanism with a variety of purposes and is very commonly used. The guardrail is generally processed and assembled by steel pipes. For forming, surface treatment and painting, the existing guardrail processing technology is complex and the processing cycle is long. At the same time, the performance of the guardrail after treatment needs to be improved. A lot of cleaning and maintenance work is required during the use process. Improper handling will easily affect the guardrail. appearance and service life. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a n...
