Purpose 90° Forming Punches and Dies
Note: Using wider dies than necessary can decrease the tonnage required
to make a bend.

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 Click to Request Quote |
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. |

 No. 1B - 20 Gauge Click to Request a Quote A combination of the Number 1B Punch and any Number 2A Die make an economical die set for light-gauge sheet metal forming, particularly for short flanges. Not recommended for high production or where punch is in short sections. |

| 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. | ||||
