Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, and more specifically, to a rust removal device for machining mechanical parts. Background Art

[0002] When mechanical parts are being processed, if anti-rust oil is not sprayed on the product in time, rust is likely to occur. At this time, a rust removal device is needed to sandblast and remove rust on the mechanical parts. The jet water flow in the existing sandblasting and rust removal device is generally a single stream or several streams arranged on a plane. When rusting the surface of the product, this sandblasting method can only remove rust on one plane of the product. When rusting multiple planes, the angle of the sandblasting tube can only be changed frequently, or the fixed position of the part can be changed, which is time-consuming and labor-intensive, and the rust removal efficiency is low; in addition, some rust removal devices have several sandblasting tubes arranged in different directions, which can simultaneously sandblast and remove rust on multiple sides of the mechanical parts, but the first and last end faces of the parts along the moving direction of the sandblasting tube are not easy to be rusted through the sandblasting tube.
