General Purpose 90° Forming Punches and Dies - scroll down this page
Commonly used for forming 90° bends. Forming bends greater than 90° is also practical by air bending. The press brake ram is adjusted to limit the depth of punch travel into the die to obtain the desired bend angle.

Click for General Purpose 30° Forming Punches and Dies
Acute Dies are the most universal type of press brake dies. Recommended as a starter set. Make air-form bends from 30° to shallow bends, and also for first operation set in hemming.

A combination of the Number 1 Punch and the Number 2 Die is the most commonly used in industry for forming 90° bends. Forming bends greater than 90° is also practical by air bending. The press brake ram is adjusted to limit the depth of punch travel into the die to obtain the desired angle. Number 1A - 14 Gauge Punch

Relief on sides of Number 1A Punch permits closer back gauge clearance and longer returns than are possible with a Number 1 Punch. Load is on punch shoulders, not on ram slot as in dies without shoulders. This punch is useful for forming up to 14 gauge with Number 2 Dies of 1/4" through 5/8" openings.

A Number 3 Punch and a Number 4 Die are used to produce 90° bends in heavy gauge metals or plate. Most forming in this category is performed by air bending, in order to keep press brake tonnage capacities to a minimum and to prevent material fracture. The inside radius of the resulting bends will be equal to, or greater than the material thivkness indicated with the different dies.
