Why Look for Metal Type in Press Brake Machine?

There are two primary types of metal type press brake machines: bottom bending and air forming. Both require different tonnages. The higher tonnage is suitable for bending thicker metals. The lower tonnage is suitable for bending thinner metals. Likewise, the bending length determines the thickness of the metal sheet that can be shaped with a press brake. Here are some tips to choose the right press brake for your needs:

What Size is Good in Press Brake Machine?

Before you begin shopping for a press brake machine, consider the type of metal you will be bending. For example, bending 1.5m of three-mm steel requires a press brake with a tonnage of eight tons per meter. The tonnage rating of your machine will determine how big your machine will need to be to accomplish the job. Tonnage is usually calculated by measuring the length and width of the die opening. More tonnage is needed for thicker materials than for thinner materials, and vice versa. Also consider what types of metals you will be bending, as soft materials need a smaller machine.

Sheet Metal Bending Machines – Rolling, Wiping, U-Bending, and Bottoming

When bending sheet metal, there are many things that you should take into consideration. There are four basic bending techniques: Rolling, Wiping, U-bending, and bottoming. Each one has its own set of advantages and disadvantages. In this article, we’ll explore all four methods and help you choose the best one for your needs. Read on to learn more! Hopefully, this article has provided you with useful information.

What is Rolling Technique in Sheet Metal Bending Machines?

A rolling method in a sheet metal bending machine should be performed with safety features. For example, the rear bending roll should be hydraulically operated and equipped with a safety trip cable. Ideally, the machine should be equipped with a safety stop button and a roll-tilting mechanism. These safety features help reduce the chance of worker injury. Additionally, the control panel should have an emergency stop button and key lock on/off power switch.

Three-roll bending machines have two fixed rolls and one adjustable roll. Two of the rolls pinch the sheet and a third one bends the metal. This makes it possible to form full tubes with little or no gap in the middle. Crowning occurs when the rolls have a slightly larger diameter in the middle than the rest of the metal. Crowning may be overcompensated with shim stock. Crowning can create a gap at the ends of thin metal. If necessary, the ends of the rolled part may be welded closed to create a tight cylinder.

How Wiping Method is done Using Sheet Metal Bending Machine?

A wipe method is used for forming bent edges on sheet metal. The sheet metal is pushed onto a wiping die and the wipe die determines the inner radius of the bend. The inner radius of the bend is also dependent on the slack between the wipe die and the punch. The inner radius of a bend should be equal to four times the thickness of the sheet, excluding any excess material.

The process of wiping is faster than folding, but it increases the risk of damaging the sheet, especially when a sharp edge is involved. Wiping is used for panel products with small profiles and is typically performed on press brakes. Wiping is one of four variations of bending, and there are many different types of bending machines. Air bending is another type of bending while bottoming and coining are two more. The machine lifts and hugs the sheet metal and bends it by pushing and pulling the die to a specified angle.

What is U-bending Method in Sheet Metal Bending Machines?

A sheet metal forming machine is a versatile tool that creates a variety of shapes from sheet metal. This process reduces the cost of making parts and improves strength while simplifying the assembly process. Its versatility makes it an ideal machine for a range of metal fabrication applications. Because of its ease of use, the U-bending sheet metal bending machine is an excellent choice for many manufacturing environments.

While operating a U-bending method, be sure to carefully align the machine to avoid warping or scratching your finished product. Before starting the bending process, clamp your sheet metal with a vice in the form blocks. Make sure to keep the bend line parallel to the guide angle of the forms. Alternatively, enlist a colleague or friend to stabilize the sheet metal. Once the sheet metal has been clamped, start tapping between the bend lines.

What is Bottoming Technique using Sheet Metal Bending Machines?

Compared to traditional bending processes, bottoming reduces spring back and improves accuracy. Typically, different bending angles and sheet thicknesses require different tools. Bottoming is done by reducing the force applied to the tool during the bending process. Below are three common examples of different bottoming techniques. Here’s a breakdown of the pros and cons of each one. The main difference between bottoming and standard bending is the process of determining the correct opening width.

During bottom bending, the punch and die are brought together so that the tip of the punch makes contact with the material. When the punch makes contact with the material, the metal is not fully bent, allowing for spring back. Because of this, it’s vital that operators understand the different bottoming methods. 

In Conclusion

Some typical sheet metal bending methods are shown above. For a variety of uses, these may be accomplished with sheet metal bending equipment. And in order to execute bends well, it is vital to comprehend these techniques.

What is CNC Bending Machine?

When you are selecting a CNC bending machine for a certain application, it’s important to understand the physics of how a CNC bends a given piece of metal. This machine has four times the deflection and fewer shims required. A smaller machine, on the other hand, requires less shim adjustment and can produce the same finished parts more quickly. One of the factors that affect bending machine deflection is the grade of the material. Stainless steel and soft aluminium, for example, require more load than low-carbon steel. The manufacturer of a CNC bending machine will have a tonnage table that will tell you the exact tonnage needed per foot of material.

Traditional bending machines require trial and error to set up the metal sheet. The operator must hold the sheet tightly so that it doesn’t shift up. Additionally, multiple bends in a single sheet require adjusting the gauge manually. Changing the opening is also a major safety concern, so be sure that the lower mould isn’t touching the material. Likewise, there should be no one working behind the bending machine while it’s operating.
