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 a radius r>3000mm, comprising the following steps: laser cutting of the plate; bending of the corner of the plate; full welding of the corner of the plate; welding and grinding; surface treatment; glaze spraying; high-temperature firing surface coating; crimping the aluminum honeycomb core, forming an arc plate by molding, and crimping the galvanized steel plate; or, sequentially crimping the aluminum honeycomb core and the galvanized steel plate, forming an arc plate by molding, and making a radius r > 3000mm The enamel arc plate is put into boxes and put into storage. The method for preparing the enamel circular arc plate with a radius r>3000mm of the present invention can realize the production of different arcs, the product has a high pass rate at one time, cancels circle forming, tendon welding, artificial shaping and other processes, and improves production efficiency.

Description

technical field [0001] The invention relates to a method for preparing an enamel arc plate with a radius r>3000mm, belonging to the technical field of architectural decoration. Background technique [0002] Enamel panels are widely used and are very common in life. They are used more often like subway stations. Many colorful wall materials are made of enamel panels. There are also walls like tunnels and architectural decorative walls. Surfaces, high-end commercial buildings, apartments, villas, schools, hotels, hospitals and other decoration fields are also using enamel panels as wall surfaces. 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 production process of t...
