Deep Drawing Sheet Metal

You also can obtain severe deep draws by forcing the metal to flow into the female draw cavity.

Deep drawing sheet metal. The process involves a punch with a round comer and a die with a large radius. 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. How is this done. The sheet metal or metal blank is placed on the die and secured.

It is thus a shape transformation process with material retention. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. 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 press is then activated to force the punch against the die with up to 400 tons of force.

The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing. It is thus a shape transformation process with material retention. This is achieved by redrawing the part through a series of dies. The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. Meaning of deep drawing. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. Din 8584 deep drawing processes are divided into three types.

The process is repeated until the component achieves the desired size and shape. Unlike a stretch drawing operation the metal is displaced into a geometry that contains nearly the same surface area as the starting blank. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions. 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.

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. As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. The deep drawings having two main categories. 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.

The metal deep drawing process is a effective method of manufacturing of cups cans and other similar deep drawing products. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn. The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions.

Metal deep drawing process. Deep drawing is a sheet metal forming process used industrially to produce cup shaped box shaped and other complex curved hollow shaped sheet parts. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it.
