Deep Drawing Sheet Metal Forming

Metal deep drawing process.

Deep drawing sheet metal forming. Smaller values for deeper forming. Excessive blank holder pressure forces the aluminum to stretch. Use just enough pressure to keep the aluminum from wrinkling or use stand offs to control the gap between the die face and the blank holder surface. 315 tons four column deep drawing hydraulic press by ce safety standards yl27series four column single movement hydraulic press for sheet metal drawing com.

The deep drawings having two main categories. It is thus a shape transformation process with material retention. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. The process is considered deep drawing when the depth of the drawn part exceeds its diameter.

Keeping friction to a minimum while controlling metal flow is the key to successful deep drawing. Sheet metal forming in a low. The metal deep drawing process is a effective method of manufacturing of cups cans and other similar deep drawing products. Metal deep drawing process of sheet metal forming.

Deep drawing shallow drawing stamping deep drawing blank holder helps prevent wrinkling and reduces springback blank holder not necessary if blank diameter blank thickness is less than 25 40. A flat sheet metal blank is formed into a hollow body open on one side or a hollow body is formed into a hollow body with a smaller cross section. Deep drawing is a sheet metal forming process used industrially to produce cup shaped box shaped and other complex curved hollow shaped sheet parts. A flat sheet metal blank is formed over a single rigid shape defning tool half by a flexible rubber diaphragm under uniform hydrostatic pressure.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. Deep drawing is a process in sheet metal forming by the mechanical action of a punch. Micro cups micro boxes may be produced with similar process configurations figure 7 for micro housing applications such as for the packaging of micro sensors and micro actuators.
