Bending Sheet Metal With A Lateral Curl

In curling the initial edge is rolled into the formed circle whereas in the tear shaped hem the initial edge is still exposed.

Bending sheet metal with a lateral curl.

Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. The stroke of slider and back gauge is adjusted automatically by double servo motors. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger. Curling is the process of forming a circular ring at the edge of the metal sheet to make it safer for handling.

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. The maximum inside diameter is 500 and the maximum material thickness is 075. Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the.

Bends specified as angles may be toleranced at plus or minus one half degree at a location adjacent to the bends. Accurl cnc machine tools anhui co ltd is an influential producer of cnc machine tools and sheet metal processing equipment based in china. 3d cad files are created using a host of different cad packages and then converted into. The whole structure of hydraulic cnc press brake tandem press brake 1.

The most defined curls are made with our cl3 design. Steel plate welded structure hydraulic transmission accumulator return holistic processed vibrating toeliminate stress high strength and good rigidity. Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed. Avoid large sheet metal parts with small bent flanges.

Market leader for sheet metal fabrication solutions and metalworking machinery such as sheet metal shear press brake and hydraulic press. This set consists of two tool sets and two strokes to. Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends. In sheet metal fabrication parts are formed from metal sheets by punching cutting stamping and bending.

Avoid large sheet metal parts with small bent flanges. Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger.
