Hot Forming Sheet Metal

A sheet metal disc is rotated at high speeds while rollers press the sheet against a tool called a mandrel to form the shape of the desired part.

Hot forming sheet metal.

645 naganathan a et al including altan t progress on fe simulation of the hot stamping process 3rd int. In most cases a certain amount of elastic deformation leads to springback which occurs after forming is complete. Hot forming is similar to cold forming but involves heating the tool used to handle the metal as well as the metal itself. Certain grades of stainless steel.

Autoform s software enables you to simulate thermal effects in sheet metal forming. Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects. Heat treatment in furnace. Hot forming has become increasingly important for the automotive industry in meeting specific requirements for lower overall weight and higher crash safety.

In sheet metal forming the final shape of a part is made from a flat metal sheet. Temperatures range from 600 c to 980 c depending on customer specifications and the material used. The part is then held under pressure for a period of time to finalize formation. Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component.

Transfer from furnace to press and drawing tool. The desired shape is achieved through plastic deformation without undergoing any machining like milling. Spinning sometimes called spin forming is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side. It is performed by bringing the hot sheet metal into contact with the hot die while the hot punch descends into the die and shapes the part.

Hot forming hot forming is a temperature and time dependent process. In essence hot forming is a matched metal tool forming process that relies on time temperature and pressure. Conference on hot sheet metal forming of high performance steel chs kassel germany june 13 16 2011. Hot forming is a range of processes developed specifically for the forming of high temperature alloys.

The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. With this method parts are formed in their soft state at elevated temperatures and then quenched in the tool. Depending on the product being formed those working directly with the product will determine the proper temperature.
