The standard press brake tools Types
Press Brake Tools Types include press brake punch, acute punch, bottom tools. This Press brake dies have a segmented and standard length for the bending process. V-dies are the most common type of die. The bottom dies for die openings can handle a variety of materials and bend angles.
Rolla V bending dies
Rolla V Dies have a cylindrical shape with an 88-degree V-notch cut. The die is an anvil over which the rocker bends the sheet.
90 degree dies
It is widely used for bottoming operations. The die opening dimension depends on material thickness.
Acute angle dies for air-bending
They can be used to produce acute, 90-degree bending angles by matched punch and die.
Gooseneckdies for return-flanging
The punch is designed to allow for clearance of already formed flanges.
a combination punch and die set that bends two angles in one stroke to produce a Z shape.
Hemming dies. Two-stage dies combining an acute angle die with a flattening tool.
There are many ways to build dies to produce seams in sheets and tubes.
A radiused bend can be produced by a rounded punch. The bottom die may be a V-die or may include a spring pad or rubber pad to form the bottom of the die.
A bead or a “stopped rib” may be a feature that stiffens the resulting part. The punch has a rounded head with flat shoulders on each side of the bead. The bottom die is the inverse of the punch.
The die forms a curled or coiled edge on the sheet.
Tube- and pipe-forming dies
a first operation bends the edges of the sheet to make the piece roll-up. Then a die similar to a curling die causes the tube to be formed. Larger tubes are formed over a mandrel.
Four-way die blocks
A single die block may have a V machined into each of four sides for ease of changeover of small jobs.
A punch can be pressed into a die to form two angles at the bottom of the sheet, forming an annular channel.
Similar to channel forming, but with a rounded bottom. Spring back may be a problem and a means may need to be provided for countering it.
While a box may be formed by simple angle bends on each side, the different side lengths of a rectangular box must be accommodated by building the punch in sections. The punch also needs to be high enough to accommodate the height of the resulting box’s sides.
Such dies have a wavy surface and may involve spring-loaded punch elements.
A die set may be built in the shape of the desired profile and form several bends on a single stroke of the press.
A rocker insert in the punch may allow for some side-to-side motion, in addition to the up-and-down motion of the press.
The Press Brake Tools types selections are based on different profiles. the Press brake Tooling tolerances should be checked before punch and die are used. the operator’s responsibility should ensure the tooling fits the specifications. as well as making adjustments when necessary.
