Metal stamping basics
Jul 15, 2016

Hardware: hardware, refers to using gold, silver, copper, iron, Tin and other metal products, casting to get artifacts, used to fixing things, processing things, decoration and so on.

Stamping: stamping is most commonly used as a hardware, it is through the punch and die plate, strip, tube and profiles such as force, to produce plastic deformation or separation, so as to obtain the required shape and size of workpiece machining methods, are artifacts is the stamping.

Stamping is by press and mold plates, strips, tubes and profiles, and other pushes, to produce plastic deformation or separation, so as to obtain the desired shape and size of the workpiece (stampings) processing method. Stamping and forging are plastic processing (or processing), collectively known as the forge. Stamping blanks are mainly of hot-rolled and cold-rolled steel sheet and strip.

The basics of stamping:

Steel in the world, 60~70% is a plate, most of which was rushed into production. Car's bodywork, chassis, fuel tanks, radiators, boiler steam drum, the shell of the container, motor, electrical iron core silicon steel sheet stamping process. Instruments, household appliances, bicycles, Office machines, containers and other products, there are a large number of stampings.

Stampings and castings, forgings, compared with a thin, uniform, light and strong features. Stamping out other methods is more difficult to make with ribs, rib, rolling or flanging of the workpiece, to increase its rigidity. As a result of precision molds, workpiece precision can reach micron level, and high repeat accuracy, specifications, Wo can punch out holes, bosses, etc.

Cold stamping is no longer subject to machining, or only require a small amount of machining. Precision stamping and cold surfaces below the stampings, but still better than casting, forging, machining less.

Stamping is efficient production methods, using composite mode, especially multi-position progressive die, can be completed in a press multi punching process, achieved by uncoiling-leveling, punching to forming and finishing the product automatically. High efficiency, good working conditions, low production costs, producing hundreds of items per minute.

Stamping is mainly classified by process and separation process and forming process can be divided into two broad categories. Separation process also known as punch, the purpose of which is to make the stamping along contour lines must be separated from the sheet, while guaranteeing the separation section of quality requirements. Forming process is designed to enable the sheet without breaking slab of plastic deformation, made into the desired shape and size of the workpiece. In practice, are often a variety of integrated processes applied to a workpiece. Blanking, bending, cutting, deep drawing, hydroforming, spinning, corrections are some of the major stamping process.
