Bending Sequence Sheet Metal

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.

Bending sequence sheet metal.

The operator holds and supports the weight of the blank. Ie identify the order in which the piece should be bent. 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.

Using the proposed method feasible bending sequences with grasping positions are obtained and the sequences are sorted in the. Tools and tool stages can be reused in a sequence depending on length of tool stage. 1 the machine is then commanded to close the gap between the punch and die. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address.

Examples of sheet metal components. 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. In the sheet metal industry skilled operators perform bending of sheet metal parts. Inventor 2009 windows xp 32 bit excel 2000.

Bending sequence during the bending sequence the blank is positioned outside the machine. Sheet metal bend sequence planning is a complex combinatorial problem. Collinear bends can be performed in a single operation. Anyone have thoughts on how to accomplish this.

This is shown in figure 11. While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. Abstract in the present study a method is proposed which generates bending sequences of a sheet metal part handled by a robot. 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. For bending the upper ram moves down into the lower die. A linear ram movement results in the bend angle. Both sides of the part move up and leave the plane.
