This method of metal forming enables the designing of expansive metal sheets as well as extrusions into intricate designs. Complex shapes can be designed in a single cycle which makes it ideal for the production of large pieces. Stretch-forming is a method of forcing metal parts such as, steel shapes, aluminum extrusions and sheet metal, into permanently curved shapes of predetermined contour. A simple explanation of the process; a straight piece .Stretch Forming is a process of elongating aluminum sheet and extrusions into complex structural configurations using various shape dies. Ducommun possesses some of the largest and most unique stretch forming presses in the .In sheet stretch forming, a large sheet metal blank is placed atop the die or stretch form block. The blank is held in place by gripping jaws which hold the edges of the sheet metal. During the cycle, the stretch form block (die) moves upward and pushes against the sheet until it forms into a contoured shape. Features like oscillating carriages .

Aluminum stretch forming is the process of forming extrusions and brake metal by the combined application of tensile and bending forces. Stretch forming keeps the extrusion under constant tension while wrapping it around a form, or die, to make parts into simple or . Sheet Metal Stretch Forming Sheet Presses are used to form large size sheet stock into contoured shapes. They are typically used in the Aerospace Industry to form the parts that make up an aircraft's skin but are not limited to this industry. The basic Sheet Press has a Die Table located at the centerline of the press and hydraulic cylinders toStretch 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 principle and characteristics of sheet metal flexible stretch forming technology was introduced, structural composition and working principle of the multi-point stretch forming die and .
The Stretch Forming Process. Stretch-forming is a method of forcing metal parts such as, steel shapes, aluminum extrusions and sheet metal, into permanently curved shapes of predetermined contour.. A simple explanation of the process; a straight piece of aluminum is gripped at each end by a pair of Collet Jaws then stretched into a state of tension.Stretch forming provides better shape control, structural integrity and surface quality than other types of metal forming. LMI has the proper equipment and expertise to stretch large sheets of metal and form thousands of complex parts, from clips and brackets to .At Stretch Forming Corporation, we understand that every project is unique. That's why we offer a range of metal forming options, providing you with the flexibility to choose the method that best suits your requirements. . SHEET METAL FORMING 750 ton Sheridan Hufford Model 46 Sheridan Gray 60 ton CNC Erco 300 ton Hufford A14 Swing arm .
In its simplest form, stretch-forming involves applying biaxial tension on a metal sheet [], as indicated in Figure 1.The material must be stretched in the axial direction as a die pushes, in a perpendicular direction, drawing the metal sheet into the desired shape [2,3,4].This process gradually produces severe plastic deformation (SPD) due to the increased stress; .Stretch Forming involves placing an extrusion along a rounded, fixed bending die which is secured with clamps on each end. The machine will then rotate the clamped ends together, bending the extrusion to angles up to 180°.

Many will say material “grows” or “stretches” as it is bent in a press brake. Technically, the metal does neither, but instead elongates. It does this because the neutral axis shifts closer to the inside surface of the material. The neutral axis is an area within the bend where the material goes through no physical change during forming . • In stretch forming, the sheet metal is clamped along its edges and then stretched over a male die (form block or form punch). • The die moves upward, downward, or sideways, depending on the particular design of the machine • Stretch forming is used primarily to make aircraft wing- skin panels, fuselages, and boat hulls. .
