Bending Sheet Metal With A Lateral Curl

Market leader for sheet metal fabrication solutions and metalworking machinery such as sheet metal shear press brake and hydraulic press.

Bending sheet metal with a lateral curl.

Curling is the process of forming a circular ring at the edge of the metal sheet to make it safer for handling. 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. Accurl cnc machine tools anhui co ltd is an influential producer of cnc machine tools and sheet metal processing equipment based in china. Avoid large sheet metal parts with small bent flanges.

Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. There is a difference between a curled edge and a tear shaped hem. Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube. This set consists of two tool sets and two strokes to.

Steel plate welded structure hydraulic transmission accumulator return holistic processed vibrating toeliminate stress high strength and good rigidity. 3d cad files are created using a host of different cad packages and then converted into. The stroke of slider and back gauge is adjusted automatically by double servo motors. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

The whole structure of hydraulic cnc press brake tandem press brake 1. Avoid large sheet metal parts with small bent flanges. In curling the initial edge is rolled into the formed circle whereas in the tear shaped hem the initial edge is still exposed. The curled edge provides strength to the edge and makes it safe for handling.

Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the. Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. 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. 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.

Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends. The maximum inside diameter is 500 and the maximum material thickness is 075. The most defined curls are made with our cl3 design.
