There are bending apps or tables that will help us choose the correct V. They all start by asking the material type and thickness and they give back an ideal V opening with some options. Each option implies a series of consequences to radius, force …

Die V-Width Selection. V-opening is determined by the work thickness:t as well as bending tonnage, product's inner radius (iR) and minimum flange length.

May 4, 2004 · The actual inside radius produced is based on a percentage of the V-die width, regardless of the sharp–radius relationship. Selecting the correct die width can be confusing because of the different methods and the different bend types—sharp, radius, and profound.

Sheet Metal Bending Guide – Bend Tables To make designing parts easier, we have summarised our suggested IR for the sheet thicknesses we offer in the following tables. These tables give the necessary information to ensure that part can be fabricated.

Use this Air Bending Force Chart to help you select the correct V opening in your die to get the bend that you want and ensure your tool selection is safe.

When air bending on a press brake, the size of the V-opening in the die basically determines the product radius formed in the bend. But which size should you choose and what consequences does this have for bending force, flat pattern, minimum leg length and markings on the product?

Jul 24, 2003 · The table below shows the correct percentage to compute the inside radius for some common material types. The 20 percent rule percentages for other materials can be estimated by comparing the tensile strengths of the material with any sheet metal supplier's material characteristics sheet.

Rolla-V dies are the best solution for parts with short flanges, tapered cuts or slots near the bending area. These dies reduce marking on sheet-metal and can offer custom solutions for impossible deep box parts

Aug 4, 2024 · A typical press brake die set consists of several key components: Upper Die (Punch): The top portion of the die set that applies downward force to the material. Lower Die (Matrix or V-die): The bottom portion that supports the material and provides the forming cavity. Guide Rails: Ensure proper alignment and positioning of the dies during ...

Nov 21, 2024 · Our air bending force chart, based on the experience data of customers from various industries worldwide, provides an authoritative guide to help you easily determine the minimum bending pressure, minimum flange length, and bending radius corresponding to different V openings when bending mild steel and stainless steel.
