Embodiment approach 1
[0042] 1) First, tape the image 3 Protect the area 1 in order to verify the thinning of the metal bottom layer before and after the removal of the ceramic layer, and clamp the blade in the fixture;
[0043] 2) Install a nozzle with a diameter of 0.3mm in the spray gun;
[0044] 3) In the case of soft limit control, slowly move the spray gun with the nozzle to the corresponding blade surface, and set the target distance to 30mm;
[0045] 4) Set the pulse water pressure of the vortex pulse water jet to remove the ceramic layer to 40MPa, the nozzle moving speed to 0.02m / s, and the incident angle to 45°, turn on the vortex pulse water jet switch, and make the nozzle along the figure 1 The direction of the white arrow in figure 1 Change the line in the direction of the black arrow in to achieve the effect of continuous and layer-by-layer peeling of the ceramic layer.
[0046] 5) After the leaf basin of the blade is removed, the 180° rotation of the blade is realized through the...
Embodiment approach 2
[0054] 1) First, clamp the two blades in the fixture;
[0055] 2) Install a nozzle with a diameter of 0.5mm in the spray gun;
[0056] 3) In the case of soft limit control, slowly move the spray gun with the nozzle to the corresponding blade surface, and set the target distance to 50mm;
[0057] 4) Set the pulse water pressure of the vortex pulse water jet to remove the ceramic layer to 60MPa, the nozzle moving speed to 0.05m / s, and the incident angle to 60°, turn on the vortex pulse water jet switch, and make the nozzle along the figure 1 reciprocate in the direction of the white arrow in ; at the same time, along the figure 1 Change the line in the direction of the black arrow in to achieve the effect of continuous and layer-by-layer peeling of the ceramic layer.
[0058] 5) After one side of the blade is removed, the 180° rotation of the blade is realized through the rotating shaft on the fixture;
[0059] 6) Utilize steps 3) and 4) to complete the removal of the ceramic...
