What are the inspection standards for metal stamping parts?3

Metal stamping parts are widely used in all aspects of our lives, and its requirements are getting higher and higher. It is necessary to have some inspection standards for metal stamping parts to ensure the quality and stability of stamping products. Next, the author will introduce you the inspection standards for metal stamping parts. 1. Part inspection guide (standard) book Simple metal stamping parts can be inspected by comparing the various dimensions marked in the drawings, followed by the use of various measuring instruments, such as tape measures, calipers, and stop gauges. In addition, pay attention to some important tolerances marked on the drawing, and whether the tolerance range is consistent with the drawing. For some high-precision products, tolerance requirements must be strict. 2. Samples of metal stamping parts For some parts without inspection tools, but with more complicated shapes that cannot be expressed by two-dimensional drawings. You can use a quadratic circle to check. The sign board is a very intuitive reference. It can be seen whether the structure is qualified, the surface treatment, and the batch front. 3. The superiority of metal stamping materials The adaptability of metal stamping materials to the stamping forming process becomes the stamping forming performance of the sheet metal, which includes: fracture resistance, moldability and shape. 1) Fracture resistance refers to the ability of stamping materials to resist rupture, which is generally measured by parameters such as forming limit; 2) Mouldability refers to the ability of sheet metal to achieve consistency with the shape of the mold during stamping; 3) Formability It refers to the ability of the part to maintain its existing shape in the mold after it is demolded. Obviously, the larger the forming limit, the better the fit and shapeability, the better the stamping performance of the material. 4. Special inspection tools for metal stamping parts The special inspection tools for metal stamping parts should be based on the actual conditions of the parts, and they need to be used skillfully. The above are the inspection standards for metal stamping parts. For products with extremely high requirements, Precision has specially developed automated visual inspection equipment for quality inspection. The automated visual inspection equipment can perform 100% inspection on the product, and the internal high-resolution dedicated camera can inspect the product from all dimensions to determine whether the product meets the standard. In this way, the goal of maximum inspection efficiency can be achieved while ensuring the quality of the parts is 100% reliable.
