How Do I Calculate Tonnage In Progressive Stamping

Forging is the process in which metal cold or heated is shaped into a component geometry through the use of multiple blows with a drop hammer or through the application of pressure with a hydraulic press.

. C E Megharaj P M Nagaraj and K Jeelan Pasha. A precision forging die of an asymmetric spur gear was designed and the design criteria were presented. There are infinite combinations of various factors possible such as properties of material being forged type of forging process the tool design die manufacturing methods etc.

Determines the optimum intereference to withstand internal pressure in a two ring and a three ring die assembly. Following are some recommended forging design principles. Calculation of the required forces for the closed-die forging processes is not simple like in the open-die forging processes.

Forging die design and Forging defects NPTEL. Of the forming process are used to find out whethei the analyzed die would sustain the forging load or not This metal flow simulation and die design piocess has been applied to two closed die forging examples one in plane-stiam condition and the othei m axisymmetric condition The results were encomaging and in close agieement with the. Also referred to as the free forging.

The most common practice is decreasing the height of the metal billet and increasing the diameter of that billet. Where the length of unsupported bar stock is more than three times its diameter and the diameter of the upset is not more than one and one-half times the diameter of the stock the bar can be upset in one blow provided the amount of unsupported stock beyond the face of the die is not greater than one and one-half times the diameter of the stock as shown in 4. 5 - Forging and Casting - 1970 p14 for a steel such as 4340 Slide 2.
