WHAT IS PROFILE BENDING MACHINE?

HOW TO CHOOSE THE RIGHT PROFILE BENDING MACHINE


To determine the proper profile bending machine, it is critical that yield strength, thickness, and diameter (or radius) of the profiles are all considered because for example, a higher yield or tighter diameter will require more pressure to form.

When determining which section bending machine is best suited for the task one has at hand, it is important to research what each profile bending machine is designed to do, and to understand the materials that one will be working with. Manufacturers can usually provide detailed information about their machines, such as capacity and yield.

Compare the manufacturer’s information about how much force a machine can produce and what kind of metals (sheet, roll, etc.) it is designed to handle, and compare this to your site’s mill certificates or other relevant information to see which section bending machine best fits your needs.

Overview

Section bending machines are very common machines in environments where metal profiles need to be formed to a specific radius or diameter. Angle iron, solid square, solid rectangle, round tubing, and pipe are the most common type of profiles used with this type of equipment.

Because of the wide variety of metals needing to be shaped, and the even wider variety of tasks requiring shaped metal, the fabrication market is full of different varieties of profile bending machines, each with its own strengths, weaknesses, and particular uses.

To determine the proper profile bending machine, it is critical that yield strength, thickness, and diameter (or radius) of the profiles are all considered because for example, a higher yield or tighter diameter will require more pressure to form.

On the application side, you will need to know the minimum diameter of the profiles to be formed.

You also need to know whether to bend H & I-beam and horizontal bend channel or pipe, because this will determine the correct type , size  and mold of the profile bending machine.

One of the key decision-making factors you should consider is not only what type of plate bender will meet your current needs, but which could also satisfy future business needs.

3-roll or 4-roll?

Choosing from Hamlet is already a difficult problem.
But to choose between a 3-roller and a 4-roller profile bending machine, I recommend choosing a three-roller.

  1. For machines with the same section modulus bending capacity, the bending capacity of the four-roller is significantly lower than that of the three-roller
  2. The four-roll machine will increase the complexity of the operation
  3. When the mold of the three-roll machine is very precise, the bending accuracy is the same for both.
  4. The price of four rollers is also expensive

Pyramidal machines vs Single pinch machines vs Double-pinch machines

For the choice between these three, please read here:Pre-bending and bending process

Production cost: The double-pinch section bending machine is the most expensive structure because there are more movable parts and, therefore, more components. The pyramidal type and the single-pinch type have roughly the same production cost.

Flexibility: Double double-pinch profile bending machines are the most flexible. During operation, the position of the profile can be kept stable on the loading side of the machine, and the profile can be bent using rolls only on the opposite side. It can also be operated in this way in a single-pinch section bending machine, but cannot be operated in a pyramid section bending machine.

Therefore, although the pyramid type and single pinch type are cost-effective, they are more labor intensive than modern similar products in the production environment.

Different bending capacity of section

The types of metal an section bending machine can process largely depends on its bending capacity, we use the section modulus to evaluate the capabilities of the machine.

Capacity is one of the most notable differences between these machines, each section bending machine has a section modulus rating.

Make a list of the materials and the size of the metal profile you work with on a regular basis and consult an expert to figure out what type of machine is best for you.

When determining which angle rolling machine is best suited for the task one has at hand, it is important to research what each a section bending machine is designed to do, and to understand the materials that one will be working with.

We provided detailed information about the section bending machines, such as capacity and yield.

YIELD STRENGTH

Regarding the yield strength of the machine, BIT machines are uniformly calculated based on the yield value of Q245, have a yield strength of between 36,000 and 38,000 pounds per square inch (PSI).

If you have special requirements, please indicate the yield strength of the metal material in the inquiry.

The yield value of Q245: refers to the yield value of this material, around 245MPa (34,075 psi).

After reading this, I think you will make the right decision.
