EVERYTHING YOU NEED TO KNOW ABOUT press brake dies/tooling
Sterling Machinery Carries New and Used Press Brake Tooling for all types of Hydraulic Press Brakes, Mechanical Press Brake and CNC Press Brakes, Standard and European Tooling Available.
Press brakes are used to form different shapes out of sheet metal. Sheet metal is less than 1/10” thick and is usually not hardened material.
Types of Press Brake Tooling:
90 Degree Forming Dies- Most commonly used in the industry for forming 90 degree bends. A greater than 90 degree bend is practical by air forming.
30-60 Degree Box Forming Dies- Popular dies can form from 30 – 60 Degrees bends
90 Degree Box Forming Dies- Popular dies can form 90 Degrees bends.
Gooseneck- For forming special shapes where a 90 degree punch would interfere, or channel forming in two strokes, gooseneck punches are ideal. The width of face and the length of the return flange are shown. If longer return flanges are required, the punches can be cut back beyond the center line, but the work capacity of the punch is reduced. They are used with 90 degree female dies.
30 Degree Forming Dies- These Dies are the most universal type of press brake dies and are especially recommended as a starter set.
Angles Greater than 30 degrees are made by air forming*. They are also used for the first operation in hemming. Female dies can be finished with flat tops.
Flattening Dies- Used to close a previously formed acute angle to a given degree of opening or to complete a hem.
Offset Dies- Offset dies form two 90 degree bends in one stroke. Dimensions show amount of offset from inside to outside of metal thickness. Sizes shown are suitable for mild steel to 18 gauge. Often, metals and heavier gauges of mild steel can be formed depending on size of offset and press brake capacity available.
European Tooling- European tooling has special tangs that hold the die in the die holders. Usually more precise tooling for more precision jobs.
Shallow Offset- Offsets can be many different sizes and angles. They are typically used for long runs and use 4 – 20% more tonnage to perform the operation.
Fourway Bottom Dies- A four way die can be made to have 4 different die openings creating a quick tool change without having to remove the lower dies from the machine.
Radius Forming- Outside flange on a radius bend can be formed in one stroke using die set
Rib Forming- Used to make radius rib channels and v ribs.
Curling- Curl the metal around the round dies or a round bar.
Channel- Different channel dies can form flat bottomed channels in one simple operation.
Standing Seam Double Flange- Form Double Flanged Seams.
Hemming- Used for forming hems into flat sheet metal.
Rocker and Wiping- Allow for difficult clearances when forming. These can be used to rock the two dies together for special forming.
