Bending sequence sheet metal.

Anyone have thoughts on how to accomplish this. This is shown in figure 11. The operator holds and supports the weight of the blank. Examples of sheet metal components.

While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. A linear ram movement results in the bend angle. Collinear bends can be performed in a single operation. 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. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. 1 the machine is then commanded to close the gap between the punch and die.

Figure 279 shows a simple sequence used to produce a channel. Tools and tool stages can be reused in a sequence depending on length of tool stage. Bending sequence during the bending sequence the blank is positioned outside the machine. Sheet metal bend sequence planning is a complex combinatorial problem.

For bending the upper ram moves down into the lower die. In the sheet metal industry skilled operators perform bending of sheet metal parts. 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. This combination allows the.

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. Inventor 2009 windows xp 32 bit excel 2000. Both sides of the part move up and leave the plane. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.
