Bottoming Sheet Metal

The optimum width of the v opening is 6 t t stands for material thickness for sheets about 3 mm thick up to about 12 t for 12 mm thick sheets.

Bottoming sheet metal.

With bottoming the inner radius of the angled sheet depends on the die s radius. For pricing and availability. By accurate we mean a more consistent bend angle. U shaped openings cannot be used.

Space is left between the sheet and the bottom of the v opening. Simply sandwich the sheet metal between two pieces of wood and clamp everything down on a table or workbench. Satin nick elliptical aluminum sheet model 57010 18 98 18 98. In air bending the sheet takes on a natural bend radius that s determined by thickness hardness and other material properties.

Set your store to see local availability add to cart. The wooden bread layers of the sandwich keep the sheet metal flat and prevent the drill bit from wandering as it bores through the sheet metal. In fact with bottoming the metal experiences what s referred to as springback which is what happens when it relaxes to a wider angle after being bent. Bottoming does two things for us.

Part of the fundamental manufacturing processes video series this program examines two of the oldest manufacturing processes. M d 24 in x 3 ft aluminum sheet metal. 22 gauge metal sheet model 801447 8 98 8 98. Free delivery with 45 order.

As the name bottom pressing suggests the punch presses the metal sheet onto the surface of the die so the die s angle determines the final angle of the workpiece. In bottoming the sheet is forced against the v opening in the bottom tool. It results in a tighter corner radius even equal to the sheet material thickness and it s more accurate. Bottom bending is often confused with air bending and leads operators to ask themselves why there is a difference in radius when bending a 90 and 80 angle.

This is because when bending the 80 the punch tip is not pressed into the sheet metal in the way bottom bending is. Hillman 24 in x 24 in cold rolled steel solid sheet metal. Bottoming bottoming is also known as bottom pressing or bottom striking. Free delivery with 45 order.
