Thermal spraying treatment system and thermal spraying treatment method

Abstract

The invention belongs to the technical field of thermal spraying, and particularly relates to a thermal spraying treatment system and a thermal spraying treatment method.In the thermal spraying treatment system, a spraying mechanism can adjust the position and the angle of a spraying head, so that the extension line of the spraying head is tangent to the surface of a workpiece, and the spraying head is fixed to the surface of the workpiece; irregular splashing when paint sprayed by the spray head makes contact with the surface of the workpiece is avoided, meanwhile, the paint is blocked through a material blocking plate, and paint splashing is further avoided; the position of a workpiece is adjusted through a positioning block, the axis of the workpiece, the axis of a first horizontal column and the axis of a second horizontal column are kept in a coincident state, the workpiece abuts against the second horizontal column through a pressing ring, and meanwhile the end face of the workpiece is tightly sucked to the end face of the pressing ring through the air pressure effect; therefore, it is guaranteed that the first horizontal column and the second horizontal column can drive the workpiece to rotate at a constant speed when rotating, the axis does not deviate when the workpiece rotates, and the surface coating thickness of the workpiece is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of thermal spraying, and in particular relates to a thermal spraying treatment system and a thermal spraying treatment method. Background technique [0002] Thermal spraying refers to heating and melting the coating material, atomizing it into extremely fine particles with high-speed airflow, and spraying it onto the surface of the workpiece at a high speed to form a coating; different coating materials can be selected according to the needs to obtain wear-resistant One or several properties in terms of damage, corrosion resistance, oxidation resistance, heat resistance, etc. CN208604189U discloses a hydraulic support column multi-station automatic thermal spraying device, comprising a base plate, a connecting seat, a moving wheel, a lateral moving frame, a moving box, a lifting frame, a spraying head, a connecting box, a control panel, auxiliary wheels, a casing, and a battery , switch, cooling cylinder st...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned thermal spraying device and the existing thermal spraying treatment system also have the following problems in the actual use process: (1) the incident angle of the coating material sprayed on the workpiece surface through the nozzle is relatively large, and the coating material will contact the workpiece surface after contacting the workpiece surface. There will be a large impact force between them, resulting in irregular splashing of the coating material, which is likely to cause injury to the operator; (2) During the process of spraying the surface of the workpiece, ensure that the axis of the workpiece is easily shifted when the workpiece is rotated, causing the surface of the workpiece to be coated.
