Bending Sequence Sheet Metal

Anyone have thoughts on how to accomplish this.

Bending sequence sheet metal.

1 the machine is then commanded to close the gap between the punch and die. Tools and tool stages can be reused in a sequence depending on length of tool stage. Figure 279 shows a simple sequence used to produce a channel. In order to carry out the bending operations a sheet of metal is placed on a die up against a backgage to locate the part precisely as shown in fig.

In the present study the optimum bend and set up sequence in sheet metal forming is determined by combining the tolerance anal ysis with fuzzy reasc ning. What i need to do is show the sequence for bending. Sheet bend design 4 machining set up planning 5 and three roll bending 6. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same.

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. Ie identify the order in which the piece should be bent. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address. Inventor 2009 windows xp 32 bit excel 2000.

In the sheet metal industry skilled operators perform bending of sheet metal parts. Sheet metal bend sequence planning is a complex combinatorial problem. This combination allows the. While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage.

Examples of sheet metal components. Bending sequence during the bending sequence the blank is positioned outside the machine. For bending the upper ram moves down into the lower die. 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.

This is shown in figure 11. Both sides of the part move up and leave the plane. Collinear bends can be performed in a single operation. A linear ram movement results in the bend angle.
