Nanpi hardware stamping parts processing plant, the inspection method of stamping parts + understanding the following points is more practical

The technicians of Nanpi Metal Stamping Parts Processing Factory have introduced some inspection methods about stamping parts. What are the contents? The following Xiaoshuo sorted out some relevant information, and let everyone take a look: Touch inspection Wipe the surface of the outer cover 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. This inspection method depends on the inspector's experience. If necessary, oilstone can be used to polish the detected suspicious area and verify it, but this method can be regarded as an effective quick inspection method. Whetstone polishing 1. First, wipe the surface of the outer cover with a clean gauze, and then use a whetstone (20×20×100mm or larger) for polishing. Use relatively small oilstone for arcs and hard-to-reach places. Grinding (for example: 8×100mm semi-circular whetstone) 2. The choice of whetstone size depends on the surface condition (such as roughness, galvanizing, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone grinding is basically along the longitudinal direction, and it fits well on the surface of the stamping parts. Some special places can also be supplemented with horizontal grinding. Oiling inspection Wipe clean the surface of the outer cover 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 that the stamping parts be erected on the car body. This method can easily find tiny pits, pits, ripples, etc. on the stamping parts.
