Sheet metal bending calculation basics - The Fabricator
2012年11月9日 · The second flat-blank-development example adds the two dimensions (from edge to the apex), and subtracts a bend deduction. In this case, the calculations use a complementary angle for the OSSB, and the dimensions are called from the edge to the apex—again, as specified in Figure 4.. Outside Setback (OSSB)
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 to conform to the die angle.
Bending Basics: The fundamentals of how to bend metal
2014年1月2日 · 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.
Tube bending basics: How to bend tubing and metal pipe - The …
2014年2月24日 · The pressure die (also called a pressure slide) supports the outside radius during bending. The pressure die can be stationary; it can follow the workpiece, sliding on rollers at the same rate the workpiece is being drawn into the bend; or it can be “boosted,” pushed with hydraulics or (more common today) electrical servomotors, further minimizing wall thinning.
Aluminum TIG welding settings: What you need to know - The …
2018年7月19日 · Manufacturing products with aluminum can help extend part life, reduce weight, and deliver greater integrity in cold temperatures, making the material well-suited for applications such as truck and trailer manufacturing, cryogenic piping, and boat components.
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 used to secure them—spools ...
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.
A guide to shielding gases for GMAW - The Fabricator
2019年7月24日 · Beyond quality issues, poor shielding gas performance can also drive up costs in the operation. A flow rate that is too high, for example, means you are wasting gas and spending more money on shielding gas than you need to.
Gas tungsten arc welding fundamentals: Understanding GTAW
2001年2月19日 · 2. Thoriated tungstenis the most common type of tungsten electrode for use on carbon and stainless steel.It can be purchased with 1 or 2 percent thorium. The thoriated tungsten starts readily and maintains a stable arc. It has a greater resistance to contamination and will maintain a sharp point and will not break down as readily as pure tungsten.
