Detection method of precision stamping parts

Precision stamping parts are widely used in people's daily life, but most people are not very clear about the purchase of precision stamping parts. Precision-More than 10 years of experience in customized processing of precision stamping parts. Next, let's introduce it to everyone. 1. Touch detection: Wipe the surface of the outer precision stamping parts with a clean sand cloth. The inspector should wear rubber gloves to touch the surface of the precision stamping part vertically. This type of inspection method depends on the inspector's work experience. When necessary, the anomalous areas to be explored can be polished with oilstone and certified in many ways, but this type of method is nothing more than a practical and rapid detection method. 2. Whetstone grinding and polishing: 1. First wipe the surface of the precision stamping parts with a clean sand cloth, and then polish and polish with oil stone (20×20×100 mm or larger), with curved areas and inaccessible areas Areas use relatively small oilstone for polishing (for example: 8×100 mm semicircular oilstone) 2. The choice of oilstone particle size distribution depends on the surface condition (such as surface roughness, hot-dip galvanizing, etc.). It is recommended to use coarse-grained oilstone. Most of the whetstone grinding and polishing position develops vertically, and it caters to the surface of precision stamping parts very well, and a part of the area can also fill the horizontal grinding and polishing. 3. Polish the soft diamond yarn, wipe the surface of the precision stamping parts with a neat sand cloth. Use a soft sand mesh close to the surface of the precision stamping part to be polished vertically to the entire surface, and all black spots and imprints will be easily detected. 4. Oil testing, wipe the surface of precision stamping parts with a clean sand cloth. Then use a neat soft brush to apply oil evenly to the entire outer surface of the stamping part in the same direction. Put the oiled stamping parts under strong light for inspection. It is proposed to erect the stamping parts on the car body. With this method, it is very easy to find the fine black spots, pits, and wave patterns on the stamping parts. 5. Look at the inspection: Look at the key to the inspection to detect abnormal appearance and macroeconomic shortcomings of precision stamping parts. 6. Tooling and fixture inspection: Put the stamping parts into the tooling and fixture, and carry out inspection on the stamping parts according to the actual operation regulations of the tooling and fixture instructions.
