Reverse Draw Forming Process| Vacuum forming |Working|ENGINEERING STUDY MATERIALS It is a complex process in which flat, sheet steel is formed into simple or more complex components. A circle or disc of sheet metal is first blanked from the coiled stock in the first station of the die. Then the flat blank is cupped around the nose of a punch and pressed into a die to form a cup. During the drawing process, the metal is formed under pressure. Forces of tension (in the steel wall) and compression (in the shell flange) are induced as the steel is stretched by the “nose” of the punch into the die. These forces tend to thin the shell wall and thicken the shell flange. Depending on the length to diameter ratio, several draws may be required to create the basic shape of the part. In the drawing process several stepped diameters may also be created in the part. A wide variety of in-die stations can be developed to provide additional features. These may include coining, bottom piercing, multiple side piercing, extruding, embossing, marking, burnishing, ironing, chamfering, flange forming, shaped flange trimming, beading, reverse drawing, and rib forming. The deep drawn metal stamping process gives deep drawn parts numerous advantages over traditionally machined, cast, or moulded parts. It can reduce costs and waste, lower assembly costs and time, and improve metal structure to produce a stronger finished part. It also provides a net shape that minimises waste. This means your part uses the minimum amount of metal required to deep draw the part, and you aren’t wasting money on metal that’s tossed in the scrap bin. tags: Reverse draw forming,forming process,reverse drawing process,drawing process,forming process PPT,reverse draw forming process PPT,reverse draw forming ppt,deep drawing,metal forming,vacuum forming,vacuum forming process,vacuum forming plastic,vacuum forming process animation,vacuum forming in hindi,vacuum forming mold making,forming process in manufacturing,forming process animation,forming process in hindi,forming process nptel,formingReverse draw forming,forming process,reverse drawing process,drawing process,forming process PPT,reverse draw forming process PPT,reverse draw forming ppt,deep drawing,metal forming,vacuum forming,vacuum forming process,vacuum forming plastic,vacuum forming process animation,vacuum forming in hindi,vacuum forming mold making,forming process in manufacturing,forming process animation,forming process in hindi,forming process nptel,forming #Engineering_Study_Materials
