Deep Drawing Process In Sheet Metal

The punch is the desired shape of the base of the part once drawn.

Deep drawing process in sheet metal.

This process involves four operations using tool and die to convert a sheet metal blank into formed sheet metal part. The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn. The deep drawings having two main categories. After these operations part finish operation such as trimming cutting cleaning or powder coating is done.

Deep drawing operation utilizes compressive and tensile forces to convert flat sheet metal blank into a hollow body. 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. The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro. The first stage of drawing cannot drawn normally in high degree of deformation.

The process is considered deep drawing when the depth of the drawn part exceeds its diameter. Many cylindrical parts like metal can pots container for food and beverages kitchen sinks automobile fuel tank etc. Deep drawing is a process of converting metal sheet into cylindrical or box shaped structure with or without changing its length and thickness. A flat sheet metal blank is formed over a single rigid shape defning tool half by a flexible rubber diaphragm under uniform hydrostatic pressure.

The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions. Deep drawing of sheet metal is performed with a punch and die. The die cavity matches the punch and is a little wider to allow for its passage as well as clearance. Meaning of deep drawing.

This is achieved by redrawing the part through a series of dies. Din 8584 deep drawing processes are divided into three types. Are deep drawing product. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.

Metal deep drawing process. Deep drawing with tools. The process involves a punch with a round comer and a die with a large radius. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it.

This setup is similar to sheet metal cutting operations. It is thus a shape transformation process with material retention. 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.
