Hydraulic Deep Drawing Press

Functional Mechanism of Hydraulic Deep Draw Press ?

Deep drawing can be defined as a process involved with sheet metal formation and shaping metal into different dimension where a metal sheet or tray is drawn radically into forming die with the help of a mechanical punch action. Therefore, it can also be defined as a shape transformation procedure which consists of material retention. This procedure is known as deep drawing when the drawn parts depth exceeds the diameter and this can be achieved by redrawing with the help of a large number of die series.

The sheet metal in the shoulder area of the die is also known as flange region and this portion generally experiences drawing stress along with a compressive tangential stress. This property is also known as material retention and the above mentioned stresses can also give a rise to flange wrinkles.

Hydraulic deep draw press is such a machine that is used for fulfilling such purposes. Moreover, with the help of blank holder one can easily prevent the wrinkles from taking place and the main function of this material is to control the flow of material into the radius of die..

The process of hydraulic deep draw press is also accomplished with other forming techniques, situated inside the press and some of those mentioned methods are Beading, bulging, curling, ironing or thinning of wall, notching, side piercing, marking or stamping, threading, trimming, rib forming, necking, extruding, coining, bottom piercing and the list is endless.
