A production method of printed steel plate positive semi-cylindrical

Abstract

The invention discloses a production method of a positive semi-cylindrical printed steel plate. The production method comprises the following steps: S1, shearing the plate: cutting the plate by means of tower punching and shearing; S2, processing the keel: cutting the transverse U-shaped groove Weld with the skeleton of the vertical U-shaped groove to form a keel; S3, bending: use two bending machines to perform bending operations on the plate, and use a round die to bend the plate multiple times, according to each bending The arc length between the points is used to control the radius of the arc; S4, assembly and reinforcement: use the assembly table to control the semicircle position, place the bent plate on the assembly table, place the welded keel on the back of the plate, and fix it; S5, Composite: use gypsum board to composite the vertical keel to the keel. The operation steps of the invention are relatively simple, and the final formed product has better quality and higher aesthetics, and after forming, all surfaces do not need to be painted, the board surface has no color difference, and the dirt is easy to clean.

Description

technical field [0001] The invention belongs to the technical field of printed steel plates, and in particular relates to a production method of a positive half cylinder of printed steel plates. Background technique [0002] Printed steel plate is a kind of product that prints and rolls the surface of the galvanized substrate after the coating process to obtain various patterns and patterns. This kind of product has the characteristics of light weight, beautiful appearance and good anti-corrosion performance. The printing can play a decorative role, and the steel substrate can play a fireproof role. [0003] The half-cylindrical decoration is a kind of decoration. The traditional half-cylindrical decoration usually has complicated operation steps in the production and processing process, and the final product quality is poor and the aesthetic effect is poor. Contents of the invention [0004] The invention overcomes the deficiencies of the prior art, and provides a produc...
