Quality problems often encountered in the production of stamping parts

by:Fortuna     2021-03-07
Stamping parts manufacturers often encounter some quality problems when producing stamping parts. Quality problems are not terrible, but they should be discovered and controlled in time, and the problems should be controlled internally as much as possible, and they should not be passed to customers. Today, Precision will introduce some quality problems often encountered in the daily production of stamping parts. 1. Adhesion and scratches: due to the friction between the raw material and the mold base or cavity, there are problems in the parts or mold functions; 2. Burrs: the key is generated in the cutting die and blanking die, and the gap between the knife edges will fluctuate Burrs appear; 3. Line deviation: When the stamping part is formed, the part that starts to touch the mold is extruded and a line is formed; 4. Concave and concave: Dirty (iron pin, rubber, dust) penetrates into the uncoiling line Causes convexities and concaves; 5. Bending: due to uneven stress, poor drawing bead pairing or poor press slider operation, bending and strain at the R-angle or embossing part of the part are caused; 6. Wrinkles: because Inadequate adjustment of the press slider, low press precision, large punching needles or large r-parts cause wrinkles at the edges or r-parts.
