The hardness test of metal stamping parts adopts Rockwell hardness
tester. Small, complex-shaped stampings can be used to test small planes
that cannot be tested on ordinary benchtop Rockwell hardness testers.
The
processing of stamping parts includes blanking, bending, deep drawing,
forming, finishing and other processes. The materials for stamping parts
are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet
and strip materials, such as carbon steel sheets, alloy steel sheets,
spring steel sheets, galvanized sheets, tin-plated sheets, stainless
steel sheets, copper and copper alloys Plate, aluminum and aluminum
alloy plate, etc.
The PHP series of portable surface Rockwell
hardness testers are ideal for testing the hardness of these stampings.
Alloy stamping parts are the most commonly used parts in the fields of
metal processing and machinery manufacturing. Stamping processing is a
processing method that uses a mold to separate or form a metal sheet.
Its application range is very broad.
The main purpose of the
hardness testing of stamping materials is to determine whether the
annealing degree of the purchased metal sheet is suitable for the
subsequent stamping processing. Different types of stamping processing
techniques require sheets of different hardness levels. The aluminum
alloy plate used for stamping parts can be tested with a Webster
hardness tester. When the material thickness is greater than 13mm, a
Barcol hardness tester can be used instead, and a barcol hardness tester
should be used for pure aluminum plates or low-hardness aluminum alloy
plates.
In the stamping industry, stamping is sometimes called
sheet forming, but it is slightly different. The so-called plate forming
refers to the forming method of plastic working with plate, thin-walled
tube, thin profile, etc. as raw materials, which is collectively
referred to as plate forming.
