Production process of guide board

Abstract

The invention relates to a production process of a guide board. The production process comprises the following steps that S01, cutting is performed, particularly, an aluminum alloy plate is selected and cut according to the design size, and a bottom plate is obtained; S02, cleaning is performed, and particularly the bottom plate is cleaned; S03, surface treatment is carried out, and particularly,the bottom plate treated in the step S02 is soaked in an alkaline cleaning agent to be cleaned, then is washed with clear water, and is dried by hot air blowing or infrared rays; S04, a reflective film is pasted, and particularly the reflective film is pasted to the surface of the bottom plate treated in the step S03; S05, character engraving is carried out, particularly, patterns and characters are arranged through a computer, and characters and patterns are directly engraved on the reflective film through a computer engraving machine; and S06, pressing is carried out, and particularly the characters and patterns on the reflective film are scraped and pressed through a rubber plate. The production process has the advantages that the manufacturing process is simple and reasonable, and theobtained guide board is good in quality.

Description

technical field [0001] The invention relates to the technical field of traffic engineering, in particular to a production process of street signs. Background technique [0002] Road signs are important indicators of road traffic, used to mark geographical location, lanes and other information. [0003] The invention patent with the publication number CN106875833A discloses a production method of a steel plate identification plate, which uses plastic spraying and then stamping, so that all stretched and compressed positions are covered by plastic powder after molding, and the plastic powder has good tensile and compressive properties, which can Eliminate the defect of cracking caused by the lack of stretchability of the traditional production method, and then stamping after silk screen printing, the surface stability of the silk screen position after stamping increases, and the wear resistance increases. This invention replaces the traditional production process with silk scr...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the steel plate in this invention is sprayed directly after blanking without cleaning, and impurities or debris generated during the blanking process of the steel plate are easy to adhere to the surface. Spraying under the condition of spraying is prone to impurities and debris blocking the spraying position, resulting in problems such as uneven spraying and poor effect
