We covered the general guidelines and uses for the various types of plate bending machines, but when you purchase a new plate rolling machine you will need to have some important information about the plate bending machine, which will help guide you in finding a machine to fit your bending application needs:
What you need to know:
The type of material
The first thing you need to do before you start searching for the best plate roll bender is to determine the type of materials you will be using in your project. Here, you’ll have to consider things such as thickness, width, diameter, strength, and yield. These elements determine the amount of pressure you’ll need and the max and min diameter and width of the plate roller you’ll use.
The minimum diameter of the bending
Taking the thickest material you will be working on and the minimum diameter you will be rolling that material down to will help determine the plate roll size. Plate rolls generally use the 1.5 rule, meaning that a diameter rolled can be no less than 1.5X the top roll diameter. Knowing the minimum diameter you need along with the yield strength of the material is critical in selecting the right plate roll.
How large diameter are you producing?
The larger the diameter rolled the more the need for additional supports around the plate roll. Most manufacturers offer side supports as an option to support the sheet being fed into the rolling process. However, your application may also call for overhead support if a large radius is required and the rolled sheet is being sent high into the air. The combination of side and overhead supports can assist in supporting the sheet during the process and avoid any back bending caused by the unsupported weight of the material itself.
The width of the material
The machine rolling width capacity is very important. The Plate Rolling Machines are available in a range of widths but consider a plate roller with a width capacity that would suit 80% of your production. The wider you go in capacity the larger the top will be. Therefore, increasing the minimum bending diameter.
The overall rolling capacity is determined by the physical length of the rolls. When purchasing a plate roll make sure you are sizing the roll length for the maximum width of the material you will be rolling, understanding that the longer the rolls the larger the roll diameter has to be in order to maintain strength under rolling pressure. The adverse reflection of that is the larger the diameter you will need to be rolling.
What is the thickness of the material you want to bend?
It is important to consider but also remain realistic on the maximum thickness of the plate required. If you are unrealistic in your selection of sheet thickness you may end up with a plate bending machine that is too large for your core production as this would also affect you’re your minimum bending diameter capacity and rolling quality on thinner material.
What is the production quantity you require?
For you to get the best plate roller machine, you need to know the quantity of your output. This will help you determine the type of plate roll machine that will resonate with these needs.
If medium to large production required electric or hydraulic sheet bending rolls a digital display for roll positions could help speed up your production.
The CNC three and NC or CNC four roll bending machines are considered to be the best for massive projects, but they boast distinct operational complexity, accuracy levels, and features. You’ll have to choose whether you’ll prefer the three-roll bending machines which are known for their versatility and affordability, or the four-roll bending machines, which are swift, accurate, and precise.
These are the critical factors that have to be taken into consideration when you select a plate bending machine. If you have a plate bending job that requires a new plate roller then contact a BIT representative to help you find the bender that will meet your specifications, production demands, and budget.
