Hot Forming Sheet Metal

With this method parts are formed in their soft state at elevated temperatures and then quenched in the tool.

Hot forming sheet metal. The hot forming process consists of the following steps. Depending on the product being formed those working directly with the product will determine the proper temperature. Certain grades of stainless steel. 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.

Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects. 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. High temperature alloys ideally suited for hot forming include. Hot forming is a range of processes developed specifically for the forming of high temperature alloys.

Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component. Autoform s software enables you to simulate thermal effects in sheet metal forming. Conference on hot sheet metal forming of high performance steel chs kassel germany june 13 16 2011. 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.

In most cases a certain amount of elastic deformation leads to springback which occurs after forming is complete. Sheet metal forming is used for industrial manufacturing in many sectors from car door to tin can. In sheet metal forming the final shape of a part is made from a flat metal sheet. Hot forming has become increasingly important for the automotive industry in meeting specific requirements for lower overall weight and higher crash safety.

Transfer from furnace to press and drawing tool. Temperatures range from 600 c to 980 c depending on customer specifications and the material used. The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. Heat treatment in furnace.

Hot forming is similar to cold forming but involves heating the tool used to handle the metal as well as the metal itself. The desired shape is achieved through plastic deformation without undergoing any machining like milling. The part is then held under pressure for a period of time to finalize formation.
