Punching Force Sheet Metal

Cnc punching is generally suitable for punching low carbon steel electrolytic plate aluminum zinc plate aluminum plate copper plate with t 3 5 4mm or less and stainless steel plate with t 3mm or less.

Punching force sheet metal. A pure punching machine with an automatic conveyor system can process sheet sizes of 1250 x 2500 mm. The maximum sheet density is up to 4 mm. How to obtain tonnage required for punching round holes. Create a raised edge in sheet metal that locks into the rolled edge of another piece.

If you want to calculate hydraulic press tonnage you can use our hydraulic press tonnage calculator. The recommended sheet thickness for cnc punching is. Punching is a process of creating a hole over a sheet metal while blanking operation is a process of creating a blank out of the sheet metal. In metal construction and the building industry use punching to produce profiles in sheet metal.

This tends to equalize the sheet stretching of both halves. Punching force calculation how to calculate punching force in tons punching force 25 x land distance x material thickness x material factor x shear factor note. Shape a dimension ld land distance. The maximum dimensions of the punching process are of course related to the selected punching machine.

Punch force kn 80 x 3 x 0 3447 82 728 kn convert into tonnage. A true 6 false 41. 1kn 112 tons station size land distance the larger the perimeter of the cut hole the larger the tonnage required. The aluminum alloy plate and the copper plate are 0 8 0mm.

Also known as dimple dies. 1 ton 8 90 kn. Sheet metal hole flaring dies create flares around already cut holes in sheet metal up to 3 16 thick to make the edges stronger and more rigid. 82 728 kn 9 81 8 43 ton punching force calculator p s.

F 0 7 t l u t s displaystyle f 0 7tl uts where t is the sheet metal thickness l is the total length sheared perimeter of the shape and uts is the ultimate tensile strength of the material. Alternatively if a sheet has symmetrical hole patterns you may be able to punch half the sheet flip it over then punch the other half. 3 1416 x 2 000 x 250 x 25 39 26 tons. A true b false 42.

Once it contacts the sheet metal surface it senses the resistance and drives the punch downward with enough force to penetrate the material. It guarentees a clean distortion free contact with the sheet metal. The punch force required to punch a piece of sheet metal can be estimated from the following equation. The ram with guide rail and guide carriage or indexing slide is shuttling the punching punch to the sheet metal.
