Description

Technical Field

[0001] The utility model belongs to the technical field of hardware processing, and in particular relates to a hardware electroplating pretreatment device. Background Art

[0002] Hardware refers to various metal devices made by physical processing such as forging, rolling and cutting of metals such as iron, steel and aluminum, such as hardware tools, hardware parts, daily hardware, construction hardware and security products. Hardware is widely used in the production and manufacturing of various industries. At present, hardware is generally electroplated after production and processing.

[0003] Electroplating is a very commonly used surface treatment process. It uses the principle of electrolysis to plate a thin layer of metal or alloy on certain metal surfaces. It prevents corrosion and improves the wear resistance, conductivity and reflectivity of hardware, while also enhancing its appearance.

[0004] Before electroplating, the surface of the hardware needs to be treated to remove the oxide scale, residue and dirt on the surface of the workpiece. In the existing sandblasting device, the workpiece is usually fixed at a certain installation position during the sandblasting process. If double-sided sandblasting is required, especially for sheet-shaped hardware, the workpiece needs to be removed from the sandblasting room, readjusted and sent into the sandblasting room for further processing. This method not only has low work efficiency, but also the workpiece is prone to bring out a lot of dust after being removed from the sandblasting room, affecting the health of the staff.
