Hot Forming Sheet Metal

Transfer from furnace to press and drawing tool.

Hot forming sheet metal. High temperature alloys ideally suited for hot forming include. Depending on the product being formed those working directly with the product will determine the proper temperature. Sheet metal forming is used for industrial manufacturing in many sectors from car door to tin can. Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects.

Certain grades of stainless steel. The hot forming process consists of the following steps. In sheet metal forming the final shape of a part is made from a flat metal sheet. 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.

Heat treatment in furnace. Conference on hot sheet metal forming of high performance steel chs kassel germany june 13 16 2011. Autoform s software enables you to simulate thermal effects in sheet metal forming. Hot forming has become increasingly important for the automotive industry in meeting specific requirements for lower overall weight and higher crash safety.

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. Temperatures range from 600 c to 980 c depending on customer specifications and the material used. 645 naganathan a et al including altan t progress on fe simulation of the hot stamping process 3rd int.

The desired shape is achieved through plastic deformation without undergoing any machining like milling. With this method parts are formed in their soft state at elevated temperatures and then quenched in the tool. Hot forming is similar to cold forming but involves heating the tool used to handle the metal as well as the metal itself. 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. In essence hot forming is a matched metal tool forming process that relies on time temperature and pressure. The part is then held under pressure for a period of time to finalize formation.
