Bending Sequence Sheet Metal

Process planning and tolerance reasoning for sheet metal forming are critical to reduce manufacturing time and to address.

Bending sequence sheet metal.

In the sheet metal industry skilled operators perform bending of sheet metal parts. 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. The operator holds and supports the weight of the blank.

This is shown in figure 11. On a sheetmetal drawing with numerous bends use bend notes to show the direction angle and bend radius of each bend. Both sides of the part move up and leave the plane. While planning for its manufacture it is important to select proper tools tool stages and sequence for collision free bending at every stage.

Bending sequence during the bending sequence the blank is positioned outside the machine. 1 the machine is then commanded to close the gap between the punch and die. Bending is one of the vital operations to obtain a three dimensional 3d shape in a sheet metal component. Collinear bends can be performed in a single operation.

Using the proposed method feasible bending sequences with grasping positions are obtained and the sequences are sorted in the. A linear ram movement results in the bend angle. For bending the upper ram moves down into the lower die. Ie identify the order in which the piece should be bent.

Anyone have thoughts on how to accomplish this. 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. Inventor 2009 windows xp 32 bit excel 2000. If parts are handled by a robot the best grasping positions for each bending and the number of repositions must be indicated in advance.

Examples of sheet metal components. This combination allows the. 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 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.
