Automatic film plating process of metal plate material

Abstract

The invention discloses an automatic film plating process of a metal plate material. A thin film and a metal plate are automatically conveyed between upper and lower combined rollers at the same time through heat combination equipment; and a high temperature of 250 DEG C of the upper and lower combined rollers is generated by heat supply of a heating system of the heat combination equipment so that the thin film and the metal plate are hotly fused together under the high temperature and the pressure of the upper and lower combined rollers. A separation layer is additionally arranged on the surface of the metal plate material so that the anti-scratching and anti-pressure capabilities of metal are improved, the conveying safety of the metal plate material is improved, and the production cost and the rejection rate are reduced; and the automation degree of a film covering process is high, labor force is saved and the production efficiency is improved.

Description

[0001] technical field [0002] The invention belongs to a film covering process, in particular to an automatic film covering process for sheet metal materials. [0003] Background technique [0004] Sheet metal materials over 0.3 mm will have cracks when they are directly cut or punched, and dust particles will adhere to the surface of metal materials after long-term storage, resulting in white spots during reprocessing. In order to overcome these problems, the existing technology is generally to thicken the drawing oil, but this method can only ensure that the material has less cracks during processing, and the processed material is more dusty, and white spots are more likely to occur during storage. However, the method of adopting a double-layer film has high cost, and it is easy to cause fracture cracks in the material during processing. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects existing in the prior art field, the ...
