Hardware stamping knowledge which the metal stamping parts and castings, forgings, compared with a thin, uniform, the characteristics of light and strong.
Metal stamping parts stamping can make other methods are difficult to manufacture with reinforcing rib, rib 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.
Hardware stamping parts 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 hundreds of pieces per minute.
Metal stamping parts 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.
Forming process is designed to make sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece.
In the actual production, is often a variety of process integrated applied to an artifact.
Cutting, bending, shear, deep drawing, bulging, spinning, correction is several main stamping process.
Metal stamping parts stamping sheet surface and internal performance of stamping has great influence on the quality of the finished product, 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;
Low strain hardening.
In the actual production, commonly used to approximate the manufacturability of stamping process test, such as deep drawing performance test, bulging performance test and other test materials stamping performance, to ensure the quality of the finished product and high qualified rate.
Metal stamping parts are widely used in every aspect of our lives, including electronics, auto parts, decorative materials, and so on.
We usually say that the stamping is generally refers to the cold stamping parts, for example, a piece of iron plate, want to turn it into a fast food dish, then have to design a set of mold, the mold of the working face is the shape of the plate, with the iron mould pressure, they became plate you want, this is the cold stamping, is directly used mold for stamping metal materials.
