ABOUT US

Some customers think of bending machine tooling as a secondary accessory in sheet metal bending, but the opposite is true. Although bending machines have developed into multi-axis, high-precision machines with self-stabilisation, it is the tooling that actually touches the workpiece during the bending process, and this requires HARSLE tooling that is both high-precision and high-quality. Customers can choose different dies to suit their needs before sectioning, and a wide range of clamps and related accessories are available.

PRESS BRAKE TOOLING

Feature Blogs & Articles

HARSLE is a press brake toolings manufacturer and we will share useful knowledge about bending tooling every week. Because HARSLE has a professional engineering team, we will offer more various press brake tooling tips and knowledge to our users.

Tooling

Arrow Punch

This type of mold is generally vertical with a relatively thin thickness, which is suitable for products to be bent from both sides.

Gooseneck Punch

This type of mold is generally used for folding groove type or products with greater depth requirements for the center of the upper mold.

Sash Punch

The elbow part of this type of mold is very narrow and is usually used for processing facades or door frames.

4V Die

The appropriate V-shaped opening width can be selected according to the bending thickness, and it can also be used with semi-circular notches.

Single-V die

The notch angle is generally between 30 degrees and 90 degrees. Compared with the multi-V die, the workpiece has more free space during the bending process.

Double-V die

Because the double-V lower mold is directly installed on the guide rail, there is no screw fixation, so the notch can be quickly switched.

Questions And Answers

What is the press brake tooling?

Press brake tools are used in conjunction with a press brake, which operates are heavy boom or press in order to shape and bend sheet metal. The press uses a punch to force the metal sheet into the die, creating a permanent crease and reshaping the metal. Press brakes and their accompanying tools operate without an external heating device; the heat and friction from the press' tools are enough to reshape the material. Press brake tools are usually steel, but other materials such as urethane do exist.

How do you choose press brake tooling?

Many people believe that the press brake tools are some insignificant accessory in metal processing, where it is quite the opposite. Despite press brakes becoming multi-axial machine with high precision, it is the tools that come into contact with the metal during bending (see the image above).
The differences among the tools of RFA, Eueopean, American and new type of grip are being slowly vanishing. Many functions that are needed for high effective bending are now implemented into the various types of tools. Whatever style of tooling and grip you might choose, make sure it meets the minimum requirements listed below.

What is press brake tooling made from?

HCHCr steel is widely used in cold forming molds, press tools, and die making industries, primarily due to excellent wear resistance, high compressive strength, greater dimensional stability, and high hardness.
Generally, the materials of press brake die including T8 steel, T10 steel, 42CrMo, and Cr12MoV. Cr12MoV is also good material.

What is a press brake punch?

Press brake punches come in a wide variety of shapes and sizes, which one you choose for any given job, will depend on the job itself. There is a vast range available, although they can be generally classified into three unique types, Goose Neck Punch, Swan Neck Punch and Acute Angle Punch. There are of course sub-divisions of these three types,with different radius on the nose to suit different material thicknesses and some can even be made specifically by us at Selmach for the more bespoke and unique tasks such as joggle and curl tooling. Knowing which type is best for which application can and will pay dividends.

What is a press brake dies?

Press brake dies is a tool used by the press brake to form a sheet metal. This tooling consists of various parts, and the different toolings are made up of different parts. It mainly realizes the processing of the shape of the parts by changing the physical state of the formed material.They are also strong, typically crafted from materials such as T8 steel, T10 steel, and the more expensive Cr12MoV or 42CrMo for high strength, superior durability and the best possible resistance to wear and tear.

What are the types of dies?

Dies also come in a wide range of types, from single Vee designs up to four, five and even six Vee versions as well as U bend and Z bend variants. Which you choose will depend on your fabrication needs but you also need to bear in mind the parameters of your Press Brake.
Types of dies include:

V-dies—the most common type of die. The bottom dies can be made with different-sized die openings to handle a variety of materials and bend angles.
Rotary bending dies—a cylindrical shape with an 88-degree V-notch cut along its axis is seated in the "saddle" of the punch. The die is an anvil over which the rocker bends the sheet.
90 degree dies—largely used for bottoming operations. The die opening dimension depends on material thickness.
Acute angle (air-bending) dies—used in air bending, these can actually be used to produce acute, 90 degree, and obtuse angles by varying how deeply the punch enters the die by adjusting the ram.
Gooseneck (return-flanging) dies—The punch is designed to allow for clearance of already formed flanges
Offset dies—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.
Seaming dies—There are a number of ways to build dies to produce seams in sheets and tubes.
Radius dies—A radiussed 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.
Beading dies—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.
Curling dies—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.
Channel-forming dies—A punch can be pressed into a die to form two angles at the bottom of the sheet, forming an angular channel.
U-bend dies—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.
Box-forming dies—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.
Corrugating dies—Such dies have a wavy surface and may involve spring-loaded punch elements.
Multiple-bend dies—A die set may be built in the shape of the desired profile and form several bends on a single stroke of the press.
Rocker-type dies—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.
