Introduction to the AAA batteries shrapnel

by:Fortuna     2021-02-02
AAA batteries shrapnel stamping compared with castings, forgings, has the characteristics of thin, uniform, light and strong. Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness. Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc. Cold stamping generally no longer by machining, or only need a small amount of machining. Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity. AAA batteries shrapnel stamping is efficient production methods, USES the compound die, especially the multi-station progressive die, it can be finished in a pressure on multichannel stamping process, realize the pick-up uncoiling, leveling, cutting to the forming and finishing of automatic production. High production efficiency, good working conditions, low production cost, general can produce thousands of pieces per minute. AAA batteries shrapnel stamping process for mainly according to classification, can be divided into separation process and forming process two kinds big. Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section. Stamping sheet surface and inner quality of stamping AAA batteries shrapnel performance influence is very big, request stamping material thickness precision, uniform; Smooth surface, no spots, no scar, no scratch, no surface crack, etc. ; Yield strength evenly, no obvious directivity; High uniform elongation; Showed low; Low strain hardening.
