Commonly used detection methods for metal stamping parts + 15 years of craftsmanship focusing on metal stamping dies

Metal stamping parts are sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the use of sheet materials, thin-walled tubes, thin profiles, etc. as raw materials for stamping processing. So what are the inspection methods? Xiaoshuo sorted out several inspection methods for you, and I will share with you below: 1. Inspection method: 1. 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 metal stamping part along the longitudinal direction of the metal 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. 2. Whetstone polishing 2.1. First, wipe the surface of the outer cover with a clean gauze, and then use oilstone (20×20×100mm or larger) for polishing. Use relatively small areas for arcs and hard to reach Whetstone polishing (for example: 8×100mm semi-circular oilstone) 2.2. The choice of oilstone particle size depends on the surface condition (such as roughness, galvanizing, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone polishing is basically along the longitudinal direction, and it fits well on the surface of the metal stamping parts. Some special places can also be supplemented with horizontal polishing. 3. Polishing of the flexible gauze Wipe the surface of the outer cover with a clean gauze. Use a flexible sand net to close the surface of the metal stamping part and polish it to the entire surface in the longitudinal direction. Any pitting or indentation will be easily found.
