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.

What i need to do is show the sequence for bending. This combination allows the. The operator holds and supports the weight of the blank. Ie identify the order in which the piece should be bent.

Tools and tool stages can be reused in a sequence depending on length of tool stage. Sheet bend design 4 machining set up planning 5 and three roll bending 6. Examples of sheet metal components. On a sheetmetal drawing with numerous bends use bend notes to show the direction angle and bend radius of each bend.

Bending is one of the vital operations to obtain a three dimensional 3d shape in a sheet metal component. A linear ram movement results in the bend angle. 1 the machine is then commanded to close the gap between the punch and die. 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.

This is shown in figure 11. Anyone have thoughts on how to accomplish this. Inventor 2009 windows xp 32 bit excel 2000. Abstract in the present study a method is proposed which generates bending sequences of a sheet metal part handled by a robot.

Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address. Bending sequence during the bending sequence the blank is positioned outside the machine. Sheet metal bend sequence planning is a complex combinatorial problem. Both sides of the part move up and leave the plane.

If parts are handled by a robot the best grasping positions for each bending and the number of repositions must be indicated in advance. For bending the upper ram moves down into the lower die. While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. In the sheet metal industry skilled operators perform bending of sheet metal parts.
