Metal Forming Methods - Term Paper Example

Stretch forming processThis method involves stretching the sheet metal and bending it simultaneously over a die to ensure that large countered parts are formed. It is usually performed on a stretch press with the piece of metal sheet secured along its edge using a grip jaw. The teeth jaws are usually attached to a carriage, which is usually subjected o a hydraulic or pneumatic force for e purpose of pulling. A stretch form block, which is referred to as a form die, is the tooling that is used during the process (Isik, Silva, Tekkaya & Martins, 2014).

It is also a solid form contour in which the sheet metal is pressed against. The orientation of the stretch press is usually vertical and a hydraulic ram is usually utilized during the process of lifting. The tensile force is increased when the die form is driven into the sheet. This action usually results in the plastic deformation f the sheet metal resulting in a new shape. When the horizontal stretches are used, the gripping jaws usually pull the sheet horizontally along the die form. The stretch forming equipment has the ability to produce different complex shapes.

Better shape control, as well as surface quality, is usually attained when the stretch forming equipment is used (Isik, Silva, Tekkaya & Martins, 2014). The process usually subjects the sheet metal into plastic as well as elastic deformation. The stretch forming process is used in various industries and different types of materials can also be developed. Stretch forming processThe stretch forming process is widely used for metal forming processes in different industries (Leotoing, Guines, Zidane & Ragneau, 2013).

This includes the automobile industry where the aluminum parts are produced through the process. In the aeronautic industry, stretch forming is applied in producing large wing edges. It is also applied in the process of developing the nose section and door panels for the aircraft. The application can be attributed to the low cost involved as well as the ability to use large sheets of metal. This process has the potential of stretching different types of metals that are used in the manufacture of aircraft (Sekar, 2014).
