Neutral Line Sheet Metal

This is not only our largest facility which includes a store and more than a football field sized warehouse full of product and processing capabilities as well as the company s corporate.

Neutral line sheet metal. Figure 2 after bending the bend area is 10 to 15 percent thinner than before bending. Neutral axis an imaginary line that has the same length after bending as it had before bending. The neutral axis position depends on the bend angle inside bend radius and method of forming. Notice how the sheet has thinned at the bend.

Look closely a figure 1. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The neutral axis s behavior is the main reason the flat part needs to be smaller than the total of the formed piece s outside dimensions. Industrial metal supply sun valley ca is conveniently off the 5 freeway in the greater los angeles area just minutes north of burbank california.

It is the area where the material neither stretches nor compresses in the bend. The location of the neutral axis varies and is based on the material s physical properties and its thickness. The line where the transition from compression to stretching occurs is called the neutral axis. If the material did not stretch at all then the neutral line would be at 50 of the material.

The neutral line also called the neutral axis is an imaginary line that can be drawn through a cross section of the workpiece that represents the locus where no tensile nor compressive stresses are present on the work. Neutral axis the location in the sheet that is neither stretched nor compressed and therefore remains at a constant length. Its location in the material is a function of the forces used to form the part and the material yield and tensile strengths. K factor the location of the neutral axis in the material calculated as the ratio of the distance of the neutral axis t to the material thickness t.
