Problems solved by technology
[0006] At present, the level of wire feeding devices is mostly manual wire feeding by the operator, which not only increases the labor intensity of the operator, but also the wire feeding parameters are unstable during the movement, and it is impossible to ensure that the metal and the light spot are focused on one point during the wire feeding process. , directly affects the efficiency and quality of spraying
For the problem that the laser spot of the wire feeding device and the metal wire are focused on one point, the determination of the wire feeding parameters has not yet been well resolved.

Embodiment Construction
[0026] like figure 1 shown. The working process of the wire feeding device for laser spraying:
[0027] (1) Wire filling preparation; install the wire reel 3 on the wire feeder shaft 2; fix the position of the laser head 12 and the wire reel 3, the laser head 12 is fixed above the workbench 17, and the wire reel 3 is located at the laser system 11 On both sides; the metal wire 7 is manually drawn from the wire reel 3 through the gap between the wire feed roller 8 and the pressure roller 4, and the compression degree is adjusted through the adjustable preload pressure lever 6 above the pressure roller 4 to ensure Compression of wire 7. The stepper motor 1 drives the wire feeding roller 3 to rotate after being powered on, and the metal wire 7 is exported and inserted into the copper pipe 9 manually.
[0028] (2) Positioning and clamping; After the metal wire 7 is led out from the copper tube 9 and passed through the wire feed nozzle 14, the gas nozzle 21 is installed on the l...

The invention relates to a synchronous wire feeding device for laser spraying. The device comprises a wire plate, a wire feeding driving device, a wire feeding control device, a steel pipe, a wire feeding port, a connecting element and an air channel system. The wire feeding device is simple to operate, short in adjusting time, and convenient to use; when in spraying, a metal wire and a laser spot can be focused to one point during the wire feeding process, so that the spraying effect is good, and the material utilization rate is high.
Description
technical field [0001] The invention relates to a synchronous wire feeding device and a wire feeding method for laser spraying, in particular to a new laser processing auxiliary equipment integrating control, drive and synchronous wire feeding. Background technique [0002] Laser spraying is a new type of material surface modification and remanufacturing technology that has emerged with the development of high-power lasers. By adding alloy materials on the surface of the substrate, the high-energy-density laser beam is irradiated to the coating material, which is instantly heated to a molten state. , and then the molten part is granulated by the jetted high-pressure gas, which is accelerated to spray onto the surface of the substrate to form a coating, thereby improving its surface hardness, wear resistance, corrosion resistance and oxidation resistance, etc., which can greatly improve the corrosion resistance of the substrate. performance and longevity. Laser spraying tech...
