Tube bending basics: How to bend tubing and metal pipe - The …
Feb 24, 2014 · 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.

Sheet metal bending calculation basics - The Fabricator
Nov 9, 2012 · 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)
Die Basics 101: Intro to stamping - The Fabricator
Apr 11, 2005 · Blanking—A dual-purpose cutting operation usually performed on a larger scale, blanking is used in operations in which the slug is saved for further pressworking.It also is used to cut finished piece parts free from the sheet metal. The profiled sheet metal slug removed from the sheet by this process is called the blank, or starting piece of …
Die Basics 101: Forming operations - The Fabricator
Jun 14, 2005 · Solid Form/Dead Hit Dies. Solid form/dead hit dies—also called crash forming dies—deform the metal using only a punch and cavity. These dies do not control metal flow and cannot prevent the metal from wrinkling or buckling.
Guidelines for tungsten electrode and color types - The Fabricator
Mar 7, 2006 · Editor's note: To read an update regarding tungsten electrodes guidelines, click here. Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
Bending Basics: The fundamentals of how to bend metal
Jan 2, 2014 · 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.
Die basics 101 starts with eight basic components - The Fabricator
Aug 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 ...
Metal Grades: Designations for grading sheet metals - The Fabricator
Sep 12, 2016 · Martensitic stainless steels (also part of the 4XX series) have more carbon than the ferritic grades. They are capable of being heat-treated to a variety of useful hardness and strength levels. However, they are not as corrosion-resistant as austenitic or ferritic grades.
