Interests: SUS base plate part Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts. Stretch forming is performed on a stretch press, in which a piece of sheet metal is securely gripped along its edges by gripping jaws. The gripping jaws are each attached to a carriage that is pulled by pneumatic or hydraulic force to stretch the sheet. The tooling used in this process is a stretch form block, called a form die, which is a solid contoured piece against which the sheet metal will be pressed. The most common stretch presses are oriented vertically, in which the form die rests on a press table that can be raised into the sheet by a hydraulic ram. As the form die is driven into the sheet, which is gripped tightly at its edges, the tensile forces increase and the sheet plastically deforms into a new shape. Horizontal stretch presses mount the form die sideways on a stationary press table, while the gripping jaws pull the sheet horizontally around the form die. Using a platen device, a part or all of the stainless steel sheet material is drawn into the concave mold cavity by the punching force of the punch to form the bottomed container. The processing of the side wall of the container in parallel with the stretching direction is a simple drawing process, and the drawing processing of a conical (or pyramidal) shaped container, a hemispherical container, a parabolic surface container, etc., further includes a stretching process.
