Description

Technical Field

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as the name during assembly.

[0003] Sheet metal parts are thin plate hardware parts, that is, parts that can be processed by stamping, bending, stretching and other means. A general definition is parts whose thickness does not change during the processing process. The corresponding parts are castings, forgings, machined parts, etc. For example, the outer iron shell of a car is a sheet metal part, and some cabinets made of stainless steel are also sheet metal parts. The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it can prevent parts from rusting and beautify the appearance of the product.

[0004] In the prior art, such as the application number 202323132263.1, the authorization announcement number CN221270656U, and the name of a sheet metal surface treatment device, the above patent discloses a sheet metal surface treatment device, including a work box, a box door is installed at the front end of the work box, a fan is installed on the top of the work box, and two parallel sides of the work box are provided with a conveying port, and two rollers are symmetrically installed on the inner side of the conveying port. A control switch is installed on one side of the work box, and the control switch is located above the conveying port. Two grinding plates are installed inside the work box, and a dust collection bin is installed on one side of the grinding plate. The bottom of the dust collection bin is in contact with the sheet metal plate. In the above patent, the dust diffusion generated during the grinding and polishing of the sheet metal surface is reduced, and the air quality in the operation room is improved.

[0005] Another example is the Chinese patent with application number 201921004340.6, authorization announcement number CN210788340U, and name CN, a sheet metal surface treatment device. The above patent discloses a sheet metal surface treatment device, including a box, a cleaning chamber, a drying chamber and a spraying chamber. The box consists of a cleaning chamber, a drying chamber and a spraying chamber. The drying chamber is located between the cleaning chamber and the spraying chamber. A water tank is embedded in the upper part of the cleaning chamber. A high-pressure pump is provided on the bottom side of the water tank. A rotating nozzle is installed on the upper side of the cleaning chamber. The high-pressure pump and the rotating nozzle are connected to each other. A sprayer is installed on one side of the outside of the cleaning chamber, and a nozzle is installed on the inside of the cleaning chamber. In the above patent, by providing a high-pressure pump, a rotating nozzle, a sprayer and a nozzle, the surface of the sheet metal is effectively cleaned, and the oil stains on the surface of the sheet metal are effectively removed.

However, during the production and processing of sheet metal parts, there are cases where the surface is uneven. Therefore, in order to ensure the needs of subsequent processing, the surface of the sheet metal parts usually needs to be polished.
