Deep Drawing Sheet Metal Ppt

Custom deep drawing metal parts sheet metal process deep metal drawing is the process of deforming a sheet metal material into a deep drawing metal parts cylindrical or box shaped part by a process of punching pulling a ring or a metal.

Deep drawing sheet metal ppt.

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. Softer metals such as aluminum are easily transformed with this technique. Deep drawing dd is one of the sheet metal forming processes widely used in automobile aerospace electronics and allied industries to produce the hollow parts.

Drawing ratio measurement of the amount of drawing performed on a sheet metal blank can be quantified with the drawing ratio higher the drawing ratio the more extreme the amount of deep drawing the drawing ratio is roughly calculated as dr db dp db diameter of the blank dp diameter of the punch 7. The edges of the metal blank are restrained by rings and the plug is drawn into a top die cavity to achieve the end shape that is desired. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.

Drawing expensive tooling no net thinning quick deep drawing shallow drawing stamping deep drawing blank holder helps prevent wrinkling and reduces springback blank holder not necessary if. Deep drawing metal stamping manufacturing technology is defined as the stretching of sheet metal stock commonly referred to as a blank around a plug. Expensive sheet metal slow very high formability technology a brief review forming speed 20 1000pts hr 7 13cycles hr 3 8pts hr 0 3 4pts hr. The process involves a punch with a round comer and a die with a large radius.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. The improvement in the deep. Punch forces a flat sheet metal into a deep die cavity cylindrical conical rectangular shaped components can be manufactured. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.

Deep drawing works great with sheet metal manufacturing methods that call for aluminum brass cold roll steel and stainless steel as well. The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn. Deep drawing by 2. Two main factors will cause the punch in deep drawing to draw the metal into the.
