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.

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. Abstract in the present study a method is proposed which generates bending sequences of a sheet metal part handled by a robot. Anyone have thoughts on how to accomplish this.

Inventor 2009 windows xp 32 bit excel 2000. The operator holds and supports the weight of the blank. Sheet bend design 4 machining set up planning 5 and three roll bending 6. 1 the machine is then commanded to close the gap between the punch and die.

For bending the upper ram moves down into the lower die. 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. This is shown in figure 11.

This combination allows the. Sheet metal bend sequence planning is a complex combinatorial problem. Ie identify the order in which the piece should be bent. What i need to do is show the sequence for bending.

Bending sequence during the bending sequence the blank is positioned outside the machine. Collinear bends can be performed in a single operation. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address. In the sheet metal industry skilled operators perform bending of sheet metal parts.

Tools and tool stages can be reused in a sequence depending on length of tool stage. If parts are handled by a robot the best grasping positions for each bending and the number of repositions must be indicated in advance. 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. Both sides of the part move up and leave the plane.
