Method of stretch forming an aluminum metal sheet and handling equipment for doing the same

摘要

A method of stretch forming an aluminum metal sheet that includes the steps of placing an aluminum metal sheet in a hot forming tool, forming a shaped part at an elevated temperature, removing the hot shaped part from the forming tool, and thereafter transferring the hot shaped part to a cooling fixture. The transfer and removal steps are performed at a speed that is variable based on a correlation of the temperature and strength of the aluminum metal sheet and the speed at which the hot shaped part may be transferred without distortion of its shape due to inertia.
