Bending Sheet Metal With A Lateral Curl

There is a difference between a curled edge and a tear shaped hem.

Bending sheet metal with a lateral curl.

Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends. 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. The most defined curls are made with our cl3 design. In curling the initial edge is rolled into the formed circle whereas in the tear shaped hem the initial edge is still exposed.

This set consists of two tool sets and two strokes to. Market leader for sheet metal fabrication solutions and metalworking machinery such as sheet metal shear press brake and hydraulic press. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the. 3d cad files are created using a host of different cad packages and then converted into.

Avoid large sheet metal parts with small bent flanges. The curled edge provides strength to the edge and makes it safe for handling. Mechanical torque system makes sure the synchronization of cylinders. Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube.

The maximum inside diameter is 500 and the maximum material thickness is 075. Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. Steel plate welded structure hydraulic transmission accumulator return holistic processed vibrating toeliminate stress high strength and good rigidity. Bends specified as angles may be toleranced at plus or minus one half degree at a location adjacent to the bends.

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. Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. The whole structure of hydraulic cnc press brake tandem press brake 1.

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.
