Description

TECHNICAL FIELD

[0001] The application relates to a fixing device, in particular to a fixing device for water-cooled plate powder spraying processing in the field of spraying devices. BACKGROUND

[0002] In a powder coating process, a water-cooled plate workpiece is usually clamped and positioned by using a frame type clamp structure. The design scheme realizes maximum effective coating area by reducing the contact surface of the non-coating area. However, in the actual production process, the open frame structure has significant process defects. Powder coating is prone to form non-uniform adhesion in the corner area of the clamp structure under the action of a high-voltage electrostatic field, especially in the shadow corner part formed by the intersection of three-dimensional space. The geometric characteristics lead to an exponential increase in the difficulty of cleaning the deposited powder. In the long-term operation process, the coating residues that are not completely removed will solidify and block under the synergistic action of mechanical stress and electrochemical corrosion, not only causing surface quality defects (such as scratches and orange peel) of the coating, but also accelerating the corrosion failure process of the clamp base material, significantly shortening the service life of the fixture and increasing the process maintenance cost.

[0003] The existing patent with the publication number CN219187385U discloses a water-cooled plate powder spraying hanger applied in the field of hanger technology.
