Die basics 101 starts with eight basic components - The Fabricator
WEBAug 8, 2006 · 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 used to secure them—spools ...
Gas tungsten arc welding fundamentals: Understanding GTAW

Bending Basics: The fundamentals of how to bend metal
WEBJan 2, 2014 · 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 ...
Bending Basics: The hows and whys of springback and springforward
WEBJul 9, 2014 · 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 to conform to the die angle.
K-factors, Y-factors, and press brake bending precision - The …
WEBMar 7, 2018 · 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.
5 steps for proper weld preparation - The Fabricator
WEBNov 25, 2020 · Enter the grinding stroke on a pull rather than on a push to help control the aggression of the grinding wheel. Grind in line with the material using smooth, even strokes rather than short, choppy strokes. This provides effective results with coated abrasives and bonded abrasives. • Avoid arm grinding.
Tube bending basics: How to bend tubing and metal pipe - The …
WEBFeb 24, 2014 · Specialty tube bending processes abound, some old and some new. Most tubes, though, are bent one of four ways: ram-type bending, roll bending, compression bending, or rotary draw bendin g. Figure 1.

Bending aluminum 101: How to bend 6061-T6 aluminum - The …
WEBAug 17, 2018 · Detune the acetylene torch and coat the area to be bent with soot. Turn back the O2 and set your rosebud tip to an ordinary flame. Heat the part uniformly until the black soot goes away. This should anneal the 6061-T6 (or other “T”) into a T-0 material. This makes the aluminum about as bendable as it can get.
Die Basics 101: Forming operations - The Fabricator
WEBJun 14, 2005 · Bending and Forming. Figure 1. Embossing. All forming operations deform sheet material by exposing it to tension, compression, or both. Most part defects, such as splits and wrinkles, occur in forming operations. Successful sheet metal forming relies heavily on the metal's mechanical properties. The …
6 steps to successful brazing - The Fabricator
WEBMar 7, 2006 · Step 1: Ensure good fit and proper clearances. Brazing uses capillary action to distribute molten filler metal between the surfaces of the base metals. So when you're brazing, maintain a clearance between the base metals to allow capillary action to work most effectively. In almost all cases, this means a close clearance.
