Problems solved by technology

The radius R of the enamel circular arc plate produced according to the existing technology must be less than 3000mm. If the radius R of the enamel circular arc plate is greater than 3000mm, the required arc cannot be guaranteed. It must be manually shaped to meet the design requirements. In the process of plastic surgery, defects such as cracks and porcelain bursts are prone to occur

Abstract

The invention discloses a method for preparing an enamel arc plate with the radius r larger than 3000 mm. The method comprises the following steps of plate laser cutting; plate corner bending; plate corner full-welding; welding and grinding; surface treatment; glaze spraying; high-temperature sintering; surface coating; and aluminum honeycomb core pressure welding, and specifically, an arc plate is formed by mold pressing and the pressure welding of a galvanized steel plate is carried out, or, the pressure welding of the aluminum honeycomb core and the galvanized steel plate is carried out sequentially, the arc plate is formed by the mold pressing so as to prepare the enamel arc plate with the radius of greater than 3000 mm, and boxing and warehousing are carried out. According to the method for preparing the enamel arc plate with the radius r larger than the 3000 mm, the manufacturing of different radians can be realized, a product is high in first-passyield, the procedures of ring circle forming, rib welding, manual shaping and the like are eliminated, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to a method for preparing an enamel arc plate with a radius r>3000mm, and belongs to the technical field of architectural decoration. Background technique [0002] Enamel panels are widely used and very common in life. They are used more often like subway stations. Many brightly colored wall materials are made of enamel panels, as well as tunnel walls and architectural decorative walls. Facades, high-end commercial buildings, apartments, villas, schools, hotels and hospitals are also using enamel panels for walls. The enamel panels do not fade and have a long service life. Therefore, the demand for enamel panels is increasing. However, the preparation process of the enamel arc plate is complicated and the yield is low. How to improve the product quality and yield of the enamel arc plate has always been a technical problem studied by those skilled in the art. [0003] The current production process of the enamel arc plate is: laser bl...
