Make what conditions need metal stampings
(2013/11/29)
By applying a force to the punch and die plates, strips , tubes and profiles , etc., so that the plastic deformation or separation, thereby forming method to obtain the shape and size of the work required to get the workpiece is stampings. Stamping presses and dies is by applying for plates, strips , tubes and profiles and other external forces , so that the plastic deformation or separation , to obtain the desired shape and size of the workpiece ( stamping ) forming processing methods. Stamping and forging belong plastic processing (or pressure processing ) , collectively known as forging . Stamping blanks are mainly hot-rolled and cold rolled steel sheet and strip
Compared with stampings castings, forgings, with a thin , uniform, light and strong features. Punching the workpiece can be made with ribs , ribs , undulating or otherwise difficult to manufacture the flange to increase its rigidity . As a result of precision molds, precision parts up to the micron level, and high repeat accuracy , consistency specifications, you can punch out holes nest , bosses, and so on.
Cold stamping generally no longer after cutting, or need only a small amount of cutting. Hot stamping accuracy and surface state below the cold stamping , but still better than castings, forgings, machining less.
Stamping is a highly efficient production methods , the use of composite modulus , especially multi-position progressive die , stamping process to be completed multi-channel on a press, implemented by strip uncoiling , flattening, punching to forming, finishing a full automated production . High production efficiency, good working conditions, low production costs, general produce hundreds per minute.
Stamping parts processing , including punching , bending , deep drawing, forming, finishing and other processes. Refers to the so-called sheet molding plates, thin-walled tubes, thin profiles, etc. as raw material for processing plastic molding method referred to as sheet metal forming , this time, the direction of plate deformation is generally not important consideration .
PHP Series Portable Superficial Rockwell hardness tester is suitable for testing the hardness of these stampings . Alloy metal stamping parts processing, machinery manufacturing the most commonly used parts. Stamping mold making process is the use of a metal plate with a separation occurs or forming processing methods. Very broad range of applications . Hardness testing of metal stamping parts Rockwell hardness. Small, stamping parts with complex shapes can be used to test the plane is very small, can not be detected on a normal desktop Rockwell hardness .
Hardness testing stamping materials , its main purpose is to determine the extent of annealed sheet metal stamping parts purchased are suitable for subsequent processing to be carried out , different kinds of stamping parts processing, require different levels of hardness plate . Aluminum alloy plate for stamping parts available Webster hardness testing, the material thickness greater than 13mm can switch bar hardness , pure aluminum or aluminum alloy plate should be used for low hardness Pap hardness.
