Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece processing, in particular to a special hanger for electrostatic spraying of multiple layers of metal workpieces. Background Art

[0002] Metal spraying is a material protection technology that creates a coating by spraying a high-speed stream of molten metal particles onto the workpiece surface. This technology is commonly used to protect large steel structures.

[0003] A Chinese patent discloses a special hanger for electrostatic spraying of multiple layers of metal workpieces, with the publication number CN214021510U. It includes a cross-shaped main frame composed of a support column and a support connecting rod. The left and right ends of the horizontally arranged support column are respectively provided with a hook support base perpendicular to the support column. The ends of the two hook support bases, which are respectively provided on the left and right sides, are each provided with a hook support connecting the two ends, thereby forming a horizontal frame structure with the support column as the symmetry axis. For flat products, this hanger can be hung front and back to release the production capacity of the double-sided spray gun. For large products, the middle beam can continue to be hung to achieve four-sided spraying.
