Deep Drawing Sheet Metal

Meaning of deep drawing.

Deep drawing sheet metal.

Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. This is achieved by redrawing the part through a series of dies. The metal deep drawing process is a effective method of manufacturing of cups cans and other similar deep drawing products. Deep drawing is a sheet metal forming process used industrially to produce cup shaped box shaped and other complex curved hollow shaped sheet parts.

Metal deep drawing process. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. The press is then activated to force the punch against the die with up to 400 tons of force.

The key to deep drawing aluminum is to avoid stretching it. The process is repeated until the component achieves the desired size and shape. Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it.

You also can obtain severe deep draws by forcing the metal to flow into the female draw cavity. The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro. How is this done. 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.

Deep drawing is a sheet metal forming process that involves complex material flow and force distributions. When first stage drawing a blank shape metal is made up of cup and that formed cup is drawn again and again and then finally reaches the require shape of cup or other similar product. It is thus a shape transformation process with material retention. Unlike a stretch drawing operation the metal is displaced into a geometry that contains nearly the same surface area as the starting blank.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. It is thus a shape transformation process with material retention.

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. The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions. The deep drawings having two main categories. As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.

The process involves a punch with a round comer and a die with a large radius. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. The sheet metal or metal blank is placed on the die and secured.
