Six inspection methods for automobile stamping parts

1. Touch inspection

Wipe the surface of the outer cover clean with a clean gauze. The inspector needs to wear touch gloves to touch the surface of the stamping part along the longitudinal direction of the stamping part.

2. Oiling inspection

Wipe the surface of the outer cover clean with a clean gauze. Then use a clean brush to apply oil evenly to the entire outer surface of the stamping in the same direction. Put the oiled stamping parts under strong light for inspection. It is recommended to erect the stamping parts on the body position.

3. Grinding of flexible gauze

Wipe the surface of the outer cover clean with a clean gauze. Use a flexible sand mesh to close to the surface of the stamping part and grind it to the entire surface in the longitudinal direction, and any pitting and indentation will be easily found.

4. Whetstone grinding

First wipe the surface of the outer cover with a clean gauze, and then use a whetstone (20×20×100mm or larger) for polishing, and use a relatively small whetstone for places with arcs and hard-to-reach places (Example: 8×100mm semi-circular whetstone)

5. Visual inspection

Visual inspection is mainly used to find abnormal appearance and macroscopic defects of stamping parts

6. Inspection tool

Put the stamping parts into the inspection tool, and test the stamping parts of Nanpi according to the operation requirements of the inspection tool manual.
