Sheet metal process design should select the most effective type ofīending process based on the nature of the desired bend and the work material. Also important is the size of theīend, bend radius, angle of bend, curvature of bend and location of bend in the When deciding on a type of metal bending process. Work piece material, size and thickness are important factors Bending Processesīending processes differ in the methods they use to plastically deform the Is also widely performed in modern manufacturing. Of differently shaped metal pieces, such as for cabinet handles. Some bending operations are specifically designed for the bending References to sheet metal work pieces may often However, many of the processes covered can also beĪpplied to plate metal as well. Sheet metal is referenced with regard to the work piece when bending processesĪre discussed in this section. Punch and die operations to create a single bend.
#Accurate tube bending series#
Sometimes it will take a series of different Punch and die action will usually be provided by a press. Range of punch-die materials varies from hardwood to carbides. Bending die materialsĪre typically gray iron, or carbon steel, but depending on the work piece, the Specific to a bending process and a desired angle of bend. There are many different punch die geometries, setups and fixtures. Most sheet metal bending operations involve a punch die type setup, although not always. Heated, to either warm or hot working temperature. Usually sheet metal bending is performed cold but sometimes the work may be The conditions of manufacture will be a factor in sheet metal process design. The effect that material properties will have in response to Important to understanding sheet metal bending and are discussed in the fundamentals of Principles of metals, particularly with regard to elastic and plastic deformation, are Metal bending enacts both tension and compression within the material. Of inertia, for cosmetic appearance and to eliminate sharp edges. In addition to creating a desired geometric form, bending isĪlso used to impart strength and stiffness to sheet metal, to change a part's moment However, bending will produce essentially no change in the thickness In some casesīending may produce a small change in sheet thickness. Of the work piece, while the volume of material will remain the same. Similar to other metal forming processes, bending changes the shape Sheet metal bending is the plastic deformation of the work over an axis, PROCESSES Metal Casting Metal Forming Metal Rolling Metal Forging Metal Extrusion Metal Drawing Powder Processesīending of sheet metal is a common and vital process in manufacturing industry.
