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 sheet metal that will be cut or …
K-factors, Y-factors, and press brake bending precision - The …
Mar 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.
Analyzing the k-factor in sheet metal bending - The Fabricator
Sep 12, 2018 · “However, the neutral axis does move toward the inside surface by a percentage, that percentage being the k-factor. This relocating or shifting of the neutral axis—from 50 percent of the material thickness to a new location equal to or less than 50 percent of the material thickness—is the reason why the part elongates during forming.
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 …

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.
