Embodiment Construction

[0006] The present invention will be further described below in conjunction with specific embodiments.

[0007] Select the hot-rolled steel strip with a thickness of 4mm, install the steel strip on the uncoiler for uncoiling production by using the feeder, trim the edge according to the size requirements of the highway guardrail, and then use the edge processing device to cut the right-angled edge of the steel plate, and cut the obtuse angle 135°, then punch holes, then use 25-mesh steel shot to clean the surface of the steel plate, remove the scale, rust, welding slag, oil stains, etc. on the surface, the rust removal level is Sa2. The bending forming process and the shearing process, that is, the corrugated metal surface with a good surface treatment is obtained, which directly enters the coating process.

Abstract

The invention relates to a novel integrative treating and producing technology of a metal face, comprising the following technical processes of decoiling a steel strip; trimming; treating corners; punching; shot blasting; chemically treating; cold bending and forming; cutting; and coating. The novel integrative treating and producing technology of the metal face integrates a forming technology and a surface treating technology of a metal panel into a whole, shortens a production line, increases production efficiency and ensures product quality.

Description

technical field [0001] The invention relates to a metal surface treatment process, in particular to a novel metal surface integrated treatment production process. Background technique [0002] In recent years, my country's expressways have developed rapidly, and the production and processing industry of metal panels has continued to expand. The traditional production of metal panels is to first produce metal panels with steel strips, after surface treatment, and finally hot-dip galvanizing or composite coating coating Anti-corrosion, that is, three independent operating processes of cold-formed metal panels, surface pretreatment and coating, which not only lengthens the process line, the production process cannot be effectively integrated, and greatly affects production efficiency. Contents of the invention [0003] In order to solve the problem of independent processes in the metal panel production process and the long production line affecting production efficiency, the p...
