Introduction . operation, forces to be applied, etc. A Project Report On DESIGN AND FABRICATION OF SHEET METAL ROLLING MACHINE Submitted By HARSHDEEP SINGH INAYATULLAH FAROOQUI Under the guidance of Prof. ALVI Mr. H. Vishwakarma Submitted as a partial fulfillment of Bachelor of Engineering B.E. Shear spinning is a process related to conventional spinning and is also known as flow turning or spin forging. However, the term "shearing" by itself refers to a specific cutting process that produces straight line cuts to separate a piece of sheet metal. 9 Boothroyd, Dewhurst and Knight Viscous Shearing of Fluids v F h F/A v/h 1 m Newtonian Viscosity Generalization: Injection molding Typical shear rate for Polymer processes (sec)-1 Extrusion 102~103 Calendering 10~102 Injection molding 103~104 Comp. . Sheet Metal fabrication jobs usually start with design drawings including precise measurements as per customer or product specifications. Therefore the first step in any sheet metal process is to cut the correct shape and sized 'blank'from larger sheet. In sheet metal forming, the magnitude and distribution of friction affect metal flow, part defects, and quality, as well as tool wear and production costs. Press tool is of stampings including cutting operations like shearing, blanking, piercing etc. Punch and die / shearing blades are used to apply shearing force and cut the material. Types of Shearing. Sheet Metal • 10.1. This paper. Shearing machines or shearing devices cutting by blades pivoted on a single axis (on an axis parallel to the blade B23D 15/10; hand-held devices B23D 29/00) Definition statement This place covers: Metal sheets, metal plates and metal bars or rods shearing devices comprising at least one elongated, The slitter knives are mounted on two arbors together with spacers . For the home workshop you would more likely use powered hand-held metal shears or tin sheet metal cutting process Hydraulic The press is driven or powered by a hydraulic cylinder Servo (Driven / Control) The press or machine is Each process is used for specific purpose and the requisite shape of the final product. `frac{h}{d_{p}}geq 0.5` Shearing Parameters • Clearance, c, between the punch and die typically between 2% and 10% of sheet metal thickness • As clearance increases, sheared edge becomes rougher It leaves a lean edge on the piece of metal is sheared or cut. Simple shearingsheets of metal are sheared along a straight line Slitting- lengthwise shearing process that is used to cut coils of sheet metal into several rolls of narrower width. There is usually not much change in the thickness of the sheet metal. As the shearing process begins, the shear blade that is moving down pulls metal from the top surface of the sheet into the gap between the radii of the shear blades. Shearing is the process of separating the sheet metal into two or more pieces, normally by cutting along a line. The mechanical forming step includes using a Punching and Shearing o 10.9. The slitting process is schematically shown in Figure 1.6. The position of the pressure pad can also affect the flow of metal. Cutting: A process done by sawing, shearing, or chiseling with manual and power tools or torching with handheld plasma torches using computer numerical computer cutters like lasers Spinning o 1010. Slitting is a sheet metal cutting process with circular knives, which is used to split wide coiled sheet metal into narrower widths or for edge trimming of rolled sheet.
