Bending Sequence Sheet Metal

A linear ram movement results in the bend angle.

Bending sequence sheet metal.

While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. Figure 279 shows a simple sequence used to produce a channel. On a sheetmetal drawing with numerous bends use bend notes to show the direction angle and bend radius of each bend. What i need to do is show the sequence for bending.

Taking the sheet metal in figure 8 as an example if the bending sequence is arranged without adhering to proper bending rules and two p type bends are performed before the ω type bend then interference will occur at the ninth bend operation. Collinear bends can be performed in a single operation. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same.

Sheet bend design 4 machining set up planning 5 and three roll bending 6. Sheet metal bend sequence planning is a complex combinatorial problem. This is shown in figure 11. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address.

Ie identify the order in which the piece should be bent. Examples of sheet metal components. This combination allows the. In the sheet metal industry skilled operators perform bending of sheet metal parts.

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. Bending is one of the vital operations to obtain a three dimensional 3d shape in a sheet metal component. For bending the upper ram moves down into the lower die. The operator holds and supports the weight of the blank.

Bending sequence during the bending sequence the blank is positioned outside the machine. Both sides of the part move up and leave the plane. Tools and tool stages can be reused in a sequence depending on length of tool stage. Anyone have thoughts on how to accomplish this.
