A Press tool is a particular type of tool that is attached to a press brake and is used to produce a high volume of components. These types of tools are predominantly used in mechanical, pneumatic and hydraulic presses to achieve their goals. There is a large number of press tools that can be used with a press brake and they all have their own unique features and perks. This guide is designed to help you understand what each of the different press tools does and what they’re suited for.
A blanking tool is able to cut the entire outer profile of a sheet of metal in a single stroke with one punch and die. The process of blanking is when you cut a flat shape out of a sheet of metal. The leftover scraps are generally chalked up to wastage or can be recycled/repurposed for another use.
When using a piercing tool, you will end up with a clean-cut hole in your sheet metal with a scrap slug. Flat holes can also be produced with a piercing tool by using a shearing action.
Cut off tool
As the name suggests, a cut off tool is used to cut off a strip of sheet metal. The dimensions of the strip are entirely up to you and what you need it for and the operation is completed in a single motion. The strips may be used for things such as further bending with other tools. There is no wastage when using the cut off tool.
Parting off tool
The parting off tool is very similar to the cut off tool. The main difference between these two is that a cut off tool uses one motion to cut off a piece and can then be fitted perfectly on the sheet. Whereas with a parting off tool, you must cut along two paths at the same time. The result is that there is some wastage and the cut off piece cannot be nestled precisely.
Using plastic deformation, the drawing tool is used to turn flat pieces of sheet metal into shapes such as cups and shells.
This press brake tool is designed to regulate the irregular waviness that is left in the sheet metal’s side after cups and shells are cut out of it.
A shaving tool’s primary use is to shave a small amount of material off the side of a hole or shape that has already been cut into sheet metal. By shaving off the small amount of material, the sides are made smoother.
This is a fairly straight-forward press tool. It is able to bend metal stampings. The bending tool is only able to apply simple bends however, meaning only straight bends can be applied. Multiple bends can be applied to a single stamping.
Coming from the same family as the bending tool, the forming tool is able to apply more complicated bends to stampings such as those that curve.
A progressive tool is any press tool that reaches its goal via multiple stages – with each stage progressing the shaping of the metal further and further until the final stage is reached. The final stage tends to just be when the shape is cut off.
With a compound tool, the blanking and piercing stages fused into one and the tool itself is inverted. There is no piercing die as the role is replaced by the blanking punch.
Combination tools are able to perform two operations simultaneously. So, an operation such as forming or drawing may be combined with a cutting operation – such as piercing, blanking and cut off. Essentially a cutting and non-cutting operation may be performed simultaneously – but two cutting operations cannot be performed at the same time.
