Automatic zinc plating system and zinc plating process

Abstract

The invention relates to an automatic plating system and a zinc plating process. The automatic plating system includes an automatic control system, a workbench, a zinc plating system, a rotary drive system, a workpiece transfer system, a workpiece degreasing and derusting system, and a heating system. Specifically, the workpiece transfer system is disposed at the front end of the workbench, the rotary drive system is arranged on the workbench, and the workpiece degreasing and derusting system, the heating system and the zinc plating system are arranged on a path over the workbench in order. The movement execution of each component is all controlled by the automatic control system. In the invention, the traditional hot dip galvanizing procedure us reformed, the automatic control system is introduced, and the required raw materials, the workpiece rotation speed, the nozzle discharge flow, the nozzle movement speed, and the surface temperature of the workpiece's coated area and other key indexes are calculated accurately, so that the production procedure can be more automated, the production process is greener, and the product quality control is leaner. Thus, the zinc plating system and the zinc plating process are in line with the transformation and upgrading trends of the traditional manufacturing industry.

Description

technical field [0001] The invention relates to an automatic galvanizing system and a galvanizing process. Background technique [0002] The galvanizing process is generally divided into two processes: cold galvanizing and hot galvanizing. Hot-dip galvanizing, also known as hot-dip galvanizing, is to degrease and derust steel workpieces to present a clean and wet surface, and immediately immerse them in a plating tank in which zinc has been heated and melted in advance to form a coating on the surface of the workpiece. The method of layer zinc coating. Cold galvanizing is to hang the workpiece that has also been degreased and derusted, showing no dirt and infiltration, on the cathode in a special electroplating tank, and zinc is used for the anode. The method of turning on the DC power supply, the zinc ions on the anode migrate to the cathode, and discharge on the cathode, so that the workpiece is coated with a zinc layer. The hot-dip galvanized coating is thicker, genera...

Problems solved by technology

[0003] The traditional hot-dip galvanizing process is to degrease and derust the steel workpiece to present a clean and wet surface, and immediately immerse it in the plating tank where the zinc has been heated and melted in advance for a period of time to see if a closed seal is formed. Whether the coating and the thickness of the coating are up to standard, the product quality control ability is poor, and the zinc in the coating tank is easy to turn into zinc oxide and lose its use value

[0004] In the lighting industry, because light poles and lamps are generally used in outdoor environments, the outdoor environmental conditions are harsh and the humidity is high. If the surface is not treated, it is easy to corrode and its service life is greatly reduced; therefore, it is often used in the lighting industry The surface of light poles and lamps is coated with a zinc layer with good anti-corrosion performance; however, due to the above-mentioned various problems, the following defects often exist: 1) The product stability is poor, and the quality cannot be effectively controlled, which often causes a batch of products to fail. Some of the quality is up to the standard, and some of the quality is defective; 2) Due to the immersion type, due to the influence of various factors such as hoisting and placement, the product may have a dead zone, resulting in a thin zinc layer, which is easy to use during use. Corroded, the service life is reduced; 3) Due to the immersion type, the zinc in the plating tank is easy to become zinc oxide and lose its use value, and if the zinc ions are discharged directly, it will cause serious pollution to the environment. cost, business burden increased
