Automatic spraying production process for wind power bolt

Abstract

The invention belongs to the technical field of wind power bolt machining, and relates to an automatic spraying production process for a wind power bolt. The automatic spraying production process for the wind power bolt comprises the steps of preheating of the wind power bolt, spraying of a paint layer of the wind power bolt, paint film sintering, cooling of an operation unit, re-spraying of the operation unit, repeated paint film sintering after re-spraying and cooling of the operation unit; a film thickness detection device is arranged on a displacement translation mechanism, and when the thickness of the paint layer on the wind power bolt does not meet the preset requirement, the re-spraying operation of the operation unit is repeated; and when the thickness of the paint layer on the wind power bolt meets the requirement, the displacement translation mechanism stops working, and the operation unit performs blanking. According to the automatic spraying production process for the wind power bolt provided by the invention, automatic circulating production of the wind power bolt from preheating, spraying, sintering, cooling and re-spraying is achieved, the production process is simple, the surface of the paint layer is evenly coated, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of wind power bolt processing, and in particular relates to an automatic spraying production process for wind power bolts. Background technique [0002] As my country adjusts its energy structure and accelerates the implementation of the energy development strategy of developing renewable energy and improving the environment, wind power is widely used as a clean energy. my country's wind power industry, especially large-capacity megawatt-level large-scale wind turbines, has developed rapidly. High-strength fasteners used in wind power equipment are required to have strong stability due to long-term field service, harsh environment, and poor maintenance conditions. Among them, the most commonly used fasteners are wind power bolts. With the increase of installed capacity, in order to meet its performance requirements, the size of wind power bolts is also getting larger and larger, and its length can reach 4 to...

Problems solved by technology

[0003] In the prior art, a coating layer is added to the surface treatment of the wind power bolts, and the wind power bolts are protected by the coating layer. The grid tooling equipped with the wind power bolts is usually manually carried and transferred into the spraying area, and the labor cost is high; Moreover, the quality of the coating layer sprayed on the surface of wind power bolts is different, and the problem of peeling off of the protective layer is prone to occur.
