Sheet metal bending calculation basics - The Fabricator
2012年11月9日 · Sheet Metal Bending Calculation. Bend Allowance (BA)BA = [ (0.017453 × Inside radius) + (0.0078 × Material thickness)] × Bend angle, which is always complementary. The length of the neutral axis is calculated as a bend allowance, taken at 50 percent of the material thickness. In Machinery’s Handbook, the K-factor for mild cold-rolled steel ...
Bending Basics: The fundamentals of how to bend metal
2014年1月2日 · Bending and Forming. Figure 1: A plate’s grains run parallel to the rolling direction. While sheet metal gauges run from 0.005 to 0.249 inch thick, aluminum and steel plate thicknesses start at 0.250 in. and go all the way up to 13 in. or even more. Likewise, plate steel varies in strengths from mild varieties to some very high-strength ...
The formula for successful punching - The Fabricator
2006年8月8日 · The Stripper. The stripper performs two vital functions during the punching process. The most obvious is to hold the workpiece material against the die as the punch approaches, penetrates, and retracts. The second and less obvious function is to hold the punch tip rigid as it punches the hole in the workpiece. The Die.
K-factors, Y-factors, and press brake bending precision - The …
2018年3月7日 · Calculating K-factors. The K-factor is defined mathematically as t/Mt, where t is the neutral axis location and Mt is the material thickness. Because of the specific properties of any given metal, there is no easy way to calculate that value perfectly, hence the chart in Figure 2.
Die basics 101 starts with eight basic components - The Fabricator
2006年8月8日 · A stamping die is a special, one-of-a-kind precision tool that cuts and forms sheet metal into a desired shape or profile. Most dies are constructed of several basic components, including die plates, shoes, die sets, guide pins, bushings, heel blocks, heel plates, screws, dowels, and keys. Dies also need stripper, pressure, and drawing pads, as well as the devices …
Die Science: Stamping 101 - Die basics - The Fabricator
2008年1月15日 · A stamping die is a special, one-of-a-kind precision tool that cuts and forms sheet metal into a desired shape or profile as the sheet metal is pressed, or stamped, between two mating components (see Figure 1). A die gets the force it needs from a press. The part produced by stamping the sheet metal between the dies in the press is called the ...
Bending Basics: The hows and whys of springback and springforward
2014年7月9日 · Figure 3 Coining, bottom bending, and air forming affect stressstrain properties differently. The curved line in the air forming zone shows how springback changes at different bend angles. In bottoming and coining, bending methods that usually produce 90-degree bend angles, the line curves to the right of the vertical axis, showing how the metal springs forward …
Identifying the right welding and cutting torch tips
2003年10月9日 · The tip of a welding or cutting torch is where the action is (see Figure 1). Welding tips usually produce positive pressure (higher than 1 pound per square inch [PSI]) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle equipped with a mixer that mixes the fuel with the ...
5 steps for proper weld preparation - The Fabricator
2020年11月25日 · 3. Prep, Clean the Surface. Once the material is cut and beveled, it’s time to prepare the surface for the initial welding pass. Removing any mill scale, chemicals, contaminants, and coatings from the base material helps ensure proper weld penetration and eliminate impurities, porosity, and inclusions.
