Bending Sequence Sheet Metal

Both sides of the part move up and leave the plane.

Bending sequence sheet metal.

Anyone have thoughts on how to accomplish this. 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. Using the proposed method feasible bending sequences with grasping positions are obtained and the sequences are sorted in the.

For bending the upper ram moves down into the lower die. Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address. Inventor 2009 windows xp 32 bit excel 2000. The operator holds and supports the weight of the blank.

1 the machine is then commanded to close the gap between the punch and die. Examples of sheet metal components. A linear ram movement results in the bend angle. Ie identify the order in which the piece should be bent.

This combination allows the. If parts are handled by a robot the best grasping positions for each bending and the number of repositions must be indicated in advance. On a sheetmetal drawing with numerous bends use bend notes to show the direction angle and bend radius of each bend. Sheet bend design 4 machining set up planning 5 and three roll bending 6.

Abstract in the present study a method is proposed which generates bending sequences of a sheet metal part handled by a robot. While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage. This is shown in figure 11. 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.

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. What i need to do is show the sequence for bending. 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.
