Stainless steel production increased in most countries during 2014
Stamping properties of stainless steel bars
Performance of the corresponding material for bulging formability, flanging formability, reaming forming properties and bending properties. To understand the stamping formability must first understand the stamping process. The basic stainless steel wire stainless steel wire and stainless steel rod stamping forming process are: drawing process, bulging, flanging process (including the reaming), bending process.
1) deep drawing process
Drawing is a kind of method of stamping process of hollow piece of flat blank by using special mold blanking or cut will be made after the opening of the.
Its characteristic is the blank in the punch driven, can flow to the concave mold, namely liquidity rely on materials and extension rate forming.
2) forming process of bulging
Bulging is forced using mold blank thickness thinning and increased surface area, stamping processing methods to get the geometry of the parts.
The characteristics of the edge pressing ring blank was crushed to death, can not flow to the concave mold, depends entirely on the extension of the material itself forming.
3) flanging forming process
Flanging is the use of the mold blank on the hole edge or rim turned into stamping processing method of vertical edge.
In the middle stage of hole flanging process, namely the punch below the material has not been fully transferred to the side before, if you stop the deformation, will be shown on the right of the forming, the forming mode called reaming, production and application are also common.
4) bending process
Bending is the plate, bar, pipe material or profile bent into certain shape and angle method of forming parts.
