Metal workpiece mark printing device

Abstract

The invention provides a metal workpiece mark printing device; a device base is pivotally provided with printing roller trains having a plurality of cases; all printing roller trains are sleeved on a support mandrel; each case is respectively driven by a drive source so as to change printing portion typefaces needing printing, thus greatly improving typeface changing efficiency, and greatly improving usage convenience; the printing device uses an impressing unit to form marks through an impressing mode, and the marks are clear and hard to erase, thus improving following construction accuracy and convenience.

Description

technical field [0001] The invention relates to a metal workpiece mark printing device, which is related to a device for printing on metal. Background technique [0002] With the development of technology and the diversification of needs, construction methods are no longer limited to traditional mud brick buildings, and steel structures with fast construction and sufficient building strength can be seen everywhere; and the main material of steel structures is through steel As the main building core, after the general steel is cut to the required size, identifiable markings must be made on the steel surface, so that the correct assembly can be carried out corresponding to the markings on the design drawings during the assembly process. [0003] However, the general way of marking on the surface of steel is to mark directly on the surface of steel with paint or ink. However, general steel needs to be galvanized and anti-rust on the surface before assembly, that is, the steel m...

Problems solved by technology

[0003] However, the general way of marking on the surface of steel is to mark directly on the surface of steel with paint or ink. However, general steel needs to be galvanized and anti-rust on the surface before assembly, that is, the steel must be degreased, acid The process of washing, cleaning agent and hot-dip galvanizing can ensure the anti-corrosion effect of the steel. After a series of anti-rust treatments, the markings made of paint or ink will produce a large amount of wear and tear, and make the markings become inconspicuous or indistinct. Accurate, which may cause misjudgment during assembly and construction, affecting subsequent construction

[0004] In addition, there are also operators who make markings on the surface of the steel by etching, but the depth of the markings made by etching is too shallow, so in the process of antirust treatment, the process of immersion plating will fill the plating layer in the etching. In the groove, it will also cause inconspicuous and unclea
