Problems solved by technology

[0004] The inventors found that the thermal spraying and rolling process of the surface coating of the plate are independent of each other, and the long time interval between the processes leads to cooling of the coating, reduced fluidity, and reduced rolling effect, and the secondary clamping of parts leads to low production efficiency
At the same time, the path synchronization control and interference problems of rolling and spraying devices need to be solved

Abstract

The invention relates to an online coating rolling device and a control method thereof, and belongs to the technical field of thermal spraying. A thermal spraying process and a rolling process are combined, a prepared high-temperature coating is rolled online, meanwhile, double rolling cutters are symmetrically arranged at the two sides of a spray gun, the motion trails of the double rolling cutters are synchronous with the spray gun, interference between the rolling cutters and the spray gun is avoided, and the online rolling device comprises a clamp, a ball screw module, a double rolling unit, the spray gun and a robot mechanical arm. Secondary clamping can be avoided, twice rolling of a single-pass coating in a single stroke of the spray gun is realized, and the production efficiency and the rolling quality are improved.

Description

technical field [0001] The invention belongs to the technical field of thermal spraying, and in particular relates to an online coating rolling device and a control method thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Thermal spraying is a kind of additive manufacturing technology. The heat source directly acts on the sprayed powder, which has the advantages of small thermal influence on the substrate, small thermal stress damage, fast droplet deposition speed, and high preparation efficiency. It can be used to prepare surface functional coatings or realize Dimensional restoration, especially suitable for spraying on the surface of the board. However, compared...
