Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece surface cleaning device, and particularly to a pulse foreign matter removing workpiece surface cleaning device. BACKGROUND

[0002] The purpose of surface treatment of workpieces is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of products. For metal castings, the commonly used surface treatment methods are mechanical polishing, chemical treatment, surface heat treatment and surface spraying, etc. Surface treatment is to clean, clean, deburr, degrease and remove oxide scale on the surface of workpieces.

[0003] In related technologies, when cleaning the surface of a workpiece, there are generally two methods. One is to generate pulse impact on the surface of the workpiece by high-pressure air, and the other is to complete the cleaning work of the surface of the workpiece by high-pressure jet impact.

[0004] However, although there are various cleaning devices for workpiece surfaces at present, there are still some problems, for example, in the air jet device for cleaning foreign matter on the surface of a product disclosed in Publication No. CN201880711U, although the foreign matter on the surface of the product can be effectively cleaned by air jetting on the surface of the product, eliminating the quality problems caused by foreign matter sticking to the appearance of the product, in the technical solution and most of the current technical solutions, high-pressure gas mostly needs to use external pressurizing equipment, such as an air compressor, to provide pressure, and the pressurizing equipment will stop pressurizing when the pressure reaches a certain value, and will continue the pressurizing operation when the pressure drops to a certain value. In this process, the air pressure slowly decreases from high to low, resulting in unstable cleaning air pressure, and the air pressure is likely to be insufficient in the later period, thereby failing to effectively clean the surface of the workpiece.
