DESC:FIELD OF INVENTION

The present invention relates to sheet metal dies. In particular, the present invention relates to joggle forming and flanging operation in the dies. More particularly, the present invention relates to special floating insert configured for overcoming the problem associated with the conventional flanging operation in sheet metal dies.

BACKGROUND OF THE INVENTION AND PRIOR ART

In the conventional flanging operation in the sheet metal dies, the panel should be held between two pads (lower and upper pad) for performing flanging operation. The panel shape is already formed during the drawing operation in a drawing die. As required, the panel needs to be flanged at one of the side thereof.

The method of performing a flanging operation in sheet metal dies (Figure 1) comprises of the following method steps:

- Panel (1) is kept on the lower pad (2) in the lower die.

- On starting the stroke, i.e. starting the downward movement of the press-ram, the upper pad (4) holds the panel (1).

- The flanging process starts with the upper inserts (5) on moving the upper pad (4) downwards.

DEFINITIONS

The metal forming or simply forming is a metalworking process to give different shapes to the metal parts and objects by subjecting them to mechanical deformation, e.g. plastic deformation. For example, sheet metal panels are is reshaped without adding or removing material and often its mass remains the same. During the plastic deformation process, the physical shape of metal sheet is permanently deformed to make sheet metal parts such as body panels.
There are many forming processes conducted on metal presses, which employ different types of dies, for example, embossing, coining, bending, flanging, drawing, extruding, joggle forming die etc.

FLANGING: This is a process of bending the edge of a metal sheet. The flanging operation uses a flanging die for wiping the metal between a punch and a lower die section. This process includes tension as well as compression of the sheet metal panel. In particular, the flanging operation is carried out for bending the metal sheet along a curve. The flanges could be either stretch flanges subjected to tensile stresses, or shrink flanges subjected to compressive hoop stresses. Normally, stretch flanges are prone to splitting, whereas shrink flanges are prone to wrinkling. The main advantages of flanging process are: repeatability and lesser skill.

JOGGLE-FORMING: This operation is also known as joggle bending, which involves offset bending process, whereby multiple bends in opposite directions, each less than 90° are produced, separated by a neutral web. Although, this is a cold-working process, some tougher alloys like Titanium may require heat addition. The main advantages of joggle-forming process are: reduced waste, faster output, lesser skill; minimum material thickness reduction as compared to conventional rolling and machining processes; and multiple forming steps can be combined, otherwise required in conventional forming processes.

Figure 1b shows a schematic layout of the upper pad 04 used in performing the conventional method of flanging and joggle forming operation in sheet metal dies. It includes an upper pad 04 and an upper insert 05. However, heavy wrinkles found here in panels after flanging operation.

Figure 2a shows a schematic layout of the lower pad 02 configured in accordance with the present invention for performing the flanging and joggle forming operation in sheet metal dies to obtain sheet metal panel which are wrinkle-free and have straight edges without waviness.

Figure 2b shows a schematic layout of the upper pad 04 configured in accordance with the present invention for performing the flanging and joggle forming operation in sheet metal dies to obtain high-quality sheet metal panel which are made right first time itself and require no reworking.

Figure 3a shows a schematic diagram of the lower pad 02 of Figure 2a incorporating a lower floating insert 9 for performing the improved flanging and joggle forming operation in sheet metal dies. A flange-insert 30 is used for flanging of outer flange and is mounted on the upper die. The flange-insert 30 is made of material M190, a flame-hardened insert normally used to trim steel, flanging and piercing dies. A lower floating insert 12 is used for forming and flanging operation by mounting it on the lower pad 02. A gas spring 16 (with gas spring locking block 14, substantially located between the lower sliding blocks 18) is also mounted on the lower pad 10 to lift lower floating insert 12.

Figure 3b shows a schematic diagram of the upper pad 04 of Figure 2b incorporating an upper floating insert 22 for performing the improved flanging and joggle forming operation in sheet metal dies. The upper floating insert 22 is also made of flame-hardened material M190 and mounted on upper pad 04. A bottom block 24, urethane 26 for holding the upper floating insert 22 under which the upper sliding block 28 is also shown here.

It includes a lower casting 10 mounted with a lower pad 02 and fitted on the press bolster 42, an upper casting 20 mounted with an upper pad 04 and fitted in the press ram 40 and a flange insert 30 fitted on the upper casting 20. The upper floating insert 12 and lower floating insert 22. The metal sheet 100 for making a body panel by flanging and joggle forming operations is initially loaded on the lower pad 02 and the lower insert 12 in its uppermost position also supporting the metal sheet 100(a).

Figure 4b shows a schematic layout of the arrangement after completion of the flanging operation of the metal sheet 100(a). It shows the press-ram 40 moved down along with the flange insert 30 down and the metal sheet 100(a) held between the upper insert 22 and lower insert 12, but not supported under the flange insert 30 is successfully flanged and a flanged metal sheet 100(b) is obtained at the end of this flanging operation.

Here, the press-ram 40 along with the upper pad 04 is moved down further to come first in contact with the upper inserts 22 and subsequently, the gas spring 16 is unlocked by the gas spring locking block 14. Now, the joggle forming operation starts, in which the flanged metal sheet 100(b) supported on the lower pad 02 remains as it is, but the continuous downward movement of the ram 40 along with upper pad 04 in contact with the upper floating insert 22 causes the lower floating insert 12 to move down to obtain the joggle formed metal sheet 100(c).
