After watching the program and reviewing this printed material, the viewer will gain a knowledge and understanding of the principles and machine methods of shearing and bending sheetmetal Experiments on sheet metal shearing. Emil Gustafsson. Division of Mechanics of Solid Materials. Department of Engineering Sciences and Mathematics. Lulea University of Technology ISBN: 978-91-7439-623-2 (pdf). ISSN. ISBN . Shearing is a process for mechanical straight cutting of sheet metal without chip formation Metal Forming. 26. Valery Marinov, Manufacturing Technology. 2.3 SHEET METALWORKING. Classification of Sheet Metalworking Processes. Basic sheet metalworking operations: (a) bending, (b) drawing, and (c) shearing; (1) as punch first contacts sheet and (2) after cutting. Force and relative motion are indicated by F SHEET METAL PROCESS. Typical shearing Operations. 1. Punching: shearing process using a die and punch where the interior portion of the sheared sheet is to be discarded. 2. Blanking: shearing process using a die and punch where the exterior portion of the shearing operation is to be discarded. 3. Perforating: 1. Cutting Operation. 2. Bending Operation. 3. Drawing. 4. Other Sheet-metal Forming. 5. Dies and Presses. 6. Sheet-metal Operation. 7. Bending of Tube Stock Cutting operation. – Plastic deformation. – Penetration (1/3 thickness). – Fracture. • Shearing using a machine called power shear or square shear. • Blanking 4. Parting: shearing the sheet into two or more pieces. 5. Notching: removing pieces from the edges. 6. Lancing: leaving a tab without removing any material. Fig. Shearing Operations: Punching, Blanking and Perforating. Forming Processes. • Bending: forming process causes the sheet metal to undergo the desired shape. Most of these products have metal casings that are made by cutting and bending sheet metal. We look at some the basic sheet metal cutting and forming processes. Shearing is similar to the process by which you cut a sheet of paper using scissors. However, the machinery used is a little different. Shearing of sheet metal between two cutting edges: (3) punch compresses and penetrates into work causing a smooth cut surface; (4) fracture is initiated at the opposing cutting edges which separates the sheet. Punching - sheet metal cutting operation where the cut piece is scrap. Sheet metal forming, also called stamping, involves operations such as cutting, Final shape is obtained by applying tensile, shear or combination of forces and stretching or shrinking the sheet metal blanks. Hydraulic or mechanical presses called stamping presses are used for the forming process.$
