Bending Sequence Sheet Metal

If parts are handled by a robot the best grasping positions for each bending and the number of repositions must be indicated in advance.

Bending sequence sheet metal.

On a sheetmetal drawing with numerous bends use bend notes to show the direction angle and bend radius of each bend. 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 is one of the vital operations to obtain a three dimensional 3d shape in a sheet metal component. 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. Sheet bend design 4 machining set up planning 5 and three roll bending 6. This combination allows the. Bending sequence during the bending sequence the blank is positioned outside the machine.

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

While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address. Using the proposed method feasible bending sequences with grasping positions are obtained and the sequences are sorted in the. This is shown in figure 11.

Examples of sheet metal components. For bending the upper ram moves down into the lower die. 1 the machine is then commanded to close the gap between the punch and die. Anyone have thoughts on how to accomplish this.

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. Inventor 2009 windows xp 32 bit excel 2000.
