A centrifugal tooling and dip coating equipment

Abstract

The application discloses a centrifugal tool, which includes a rotating sleeve, which is used to cooperate with the rotating drive mechanism; a support plate, which is fixedly connected with the rotating sleeve, and several workpiece positioning parts are fixed on the support plate; The workpiece is used to constrain the movement of the workpiece, so that the workpiece rotates with the support plate under the drive of the support plate; the workpiece positioning member includes a first positioning structure and a second positioning structure; the workpiece is a hollow column, and the side of the hollow column is in contact with the support plate ;The first positioning structure is a U-shaped groove, and one end of the hollow column is located inside the U-shaped groove; the second positioning structure is used to cooperate with the first positioning structure, so that the hollow column is always in the U-shaped groove and the second positioning structure during the rotation process between. The present application also provides a dip coating device. The centrifugal tooling provided by this application can effectively avoid the accumulation between the workpieces to be processed, increase the contact between the dipping liquid and the workpiece, prevent the adhesion between the workpieces, optimize the coating effect, and make the coating thickness on the surface of the workpiece uniform.

Description

technical field [0001] The invention relates to the technical field of dacromet coating processing, in particular to a centrifugal tool and dip coating equipment. Background technique [0002] Dacromet is the transliteration and abbreviation of DACROMET, abbreviated as Dacromet, Dacromet, and Dickron. Domestically named zinc-chromium coating, it is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components. Compared with traditional metal surface anti-corrosion treatments such as electroplating and galvanizing, Dacromet anti-corrosion is a new technology and process for metal surface anti-corrosion that is environmentally friendly and can greatly improve anti-corrosion performance. [0003] Dacromet coating process can be roughly divided into dip coating, spray coating, hanging coating and other types, mainly dip coating. Dip coating is characterized by high production efficiency, simple operation, and le...

Problems solved by technology

This kind of centrifugal basket has the following problems in the working process: (1) Due to the action of gravity, the backlog of workpieces at the bottom of the centrifugal basket is relatively serious, resulting in uneven thickness of Dacromet coating on workpieces, and fluid accumulation in holes cannot be discharged or even blocked. (2) The dacromet coating itself has a certain viscosity, coupled with the centrifugal force and gravity, so that the backlog of workpieces stick together and cannot be completely separated. After curing and sintering, the workpieces stick together and Formation of lumps, high reject rate
