What factors affect the dimensional accuracy of precision stamping parts?

by:Fortuna     2021-03-06
The dimensional accuracy of precision stamping parts refers to the difference between the actual size of the finished stamping part and the standard size. The smaller the difference, the higher the dimensional accuracy of the stamping part. The dimensional accuracy of precision stamping parts is very important. Sometimes a little error will affect the use of the entire product. Therefore, some customers in the precision application industry have strict requirements on the dimensional accuracy of stamping parts. For metal precision stamping plants, the dimensional accuracy of the precision stamping parts produced is particularly important. So what factors will affect the dimensional accuracy of precision metal stamping parts? The precise author tells you. 1. Stamping die accuracy: Precision stamping parts are formed by stamping dies, so the accuracy of the stamping die will have a direct impact on the dimensional accuracy of the finished precision stamping parts. The higher the accuracy of the mold, the higher the dimensional accuracy of the produced stamping parts. 2. Concave and convex mold gap: When the convex and concave mold gap is too large, the drawing effect of the material during the stamping process will be greater, and the drawing deformation of the product will be greater, so dimensional errors will also occur. 3. The nature and thickness of the material: The dimensional accuracy of precision stamping parts is also directly related to the nature of the material used. The nature of the material determines the elastic deformation of the sheet during the stamping process. When using softer materials, the amount of elastic deformation is small, and the amount of elastic recovery after punching is also small; when using harder materials, the amount of elastic deformation is large, and the amount of elastic recovery after punching is also larger.
