Spraying system and method

Abstract

The invention provides a spraying system and method. The spraying system involves an oil spraying device and a stamping device, wherein the stamping device comprises an upper die and a lower die arranged below the upper die, and the lower die is used for placing a workpiece to be flanged; and the oil spraying device comprises an oil storage tank, an air supply source, a spraying gun and a pressure reducing valve, the air supply source is connected with the pressure reducing valve through an air pipe, the oil storage tank is connected with the pressure reducing valve through an oil pipe, the pressure reducing valve is further connected with the spraying gun through an oil-air mixing pipe, and the spraying gun and the lower die are arranged at a first preset distance. According to the spraying system, automatic oil spraying can be achieved by controlling opening and closing of the air supply source, and automatic oil spraying can be achieved by controlling opening or closing of the spraying gun; due to the fact that oil is coated by adopting an atomized oil mode, the amount of sprayed oil is small and uniform, the oil spraying amount is easy to control, and poor quality such as oil marks cannot occur on a workpiece; and the spraying system has the advantages that automatic oil spraying can be achieved, and the oil amount is easy to control. The above workpiece to be flanged can be an aluminum plate.

Description

technical field [0001] The invention relates to the field of fuel injection systems, in particular to a spraying system and method. Background technique [0002] In the existing automobile industry, realizing the lightweight of automobiles has always been the goal of automobile OEMs. Because the aluminum plate has the advantages of low density and light weight, the steel plate of the car cover is gradually replaced by the aluminum plate without affecting the quality of the car. However, it is difficult to achieve stable and high-quality production of aluminum plates. For example, compared with iron plates, aluminum plates are more likely to have poor quality in the flanging process. The main problems are plate strain, mold flanging surface strain, and aluminum powder produced by plate and mold strain floating to the mold. profile, causing indentations on the panel. The measures taken in the prior art are to apply butter to the parts of the aluminum plate that are easy to ...
