Elliptical cutting and flanging machine
Elliptical cutting and flanging is a metalworking operation, applied on round sheet metal parts such as caps, pots and pans. Elliptical cutting and flanging machine is a special metalworking machine used to cut and bend the edges of round parts made from sheet metal. The machine is capable of flanging (bending the edges in a hollow round shape inside or outside the part) round metal parts such as cookware, kitchenware, pots, pans, canisters, cans, kettles, teapots and etc. The elliptical cutting and flanging machine can curl the edges of sheet metal starting from 0.5 mm up to 10 mm in thickness. The principle of work of the machine is similar to the edge cutting and trimming machine. The parts in shape of cylinder tubes are put on the mold of the machine, then the upper mold is fixed from the top with the help of the pneumatic cylinder and after the part is fixed, the downside mold starts to rotate the part. Meanwhile the bending tool starts to move to the part direction and when the curling tool touches the edge of the part, the tool starts to curl it. The curl here is a hollow round geometry, made by the edge of the round sheet metal part. The cycle takes no more than 8 seconds and the upper molds move up and the part is ready to be taken. During the elliptical cutting operation, there comes out no chips or burrs.
