How to choose the right plate rolling machine for your needs

 

Although it is one of the most complicated fabrication processes, plate rolling is essential if you want to provide your customers with more bending options. However, unlike a press brake, which delivers a single bend in one direction of inertia, a plate rolling machine features multiple forces and different courses when the plate rolling process is taking place.

Plate rolling is an art, which needs an experienced operator who understands how to control all the intricacies of this sophisticated piece of equipment and the reaction the material he is working with will have. But besides having a skilled operator, it is also crucial that you match the right machinery to a particular job. This article provides some insightful tips on how to select the best plate roll for your plate rolling project.

For you to know which plate roller best fits your projects, you need to answer these questions:

Which types of materials will you be working with?

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.

What’s the minimum diameter?

Taking the thickest material you will be working 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.

Are you rolling only round objects or are you rolling out-of-round?

Any plate roll can produce the required round cylinders but when special shapes are required it takes a machine equipped with a CNC control to manipulate the rolls position in conjunction with the desired speed that the rolls are turning. Whether you’re rolling ovals such as fuel tanker trailer skins or some oyster non-round shape a CNC control will take all the guesswork out of roll speed and roll positions.

How large a diameter are you producing?

The larger the diameter rolled the more the need for additional supports around the plate roll. Most manufacturer’s offer side supports as an option to support the sheet being fed into the rolling process. However your application may also call for an 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.

How much are You producing?

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. The three and four roll 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 machines that are known for their versatility and affordability, or the four roll machines, which are swift, accurate, and precise.

plate rolling machine structure

How the internal structure of the sheet metal rolling machine is designed?

How the internal structure of the sheet metal rolling machine is designed?

 

Do you know how the internal structure of the sheet metal rolling machine is designed? There are many types of rolling machines, how many parts do they have in their internal structure, and how are these parts designed?

One

Take symmetrically adjusted three-roll sheet metal rolling machine as an example. The two lower rollers are active rollers with fixed positions, and the upper roller is a movable roller that can move up and down. With the help of the clutch, the upper roller can be adjusted to the parallel or inclined position with respect to the lower roller to meet the needs of rolling round or conical workpieces. Three rollers are installed on the left and right frames to form the main body of the machine. The transmission system is all arranged on the right side of the right frame, and the frame and the transmission part are arranged on the integral welded base to form the main body of the machine. The electric control console is located in front of the machine. In order to indicate the up-and-down displacement of the upper roller, pointers and scales are set on the right frame and the bearing. In order to facilitate the removal of the cylindrical workpiece from the upper roller, a turning bearing is provided at the left end of the upper roller, and a tilting adjustment structure is provided at the right end.

 

The positive and negative rotation of the lower roller, the lifting, tilting, and leveling of the upper roller are controlled by electrical appliances, the disengagement and closing of the flip bearing of the discharge, the position adjustment of the tilting adjustment mechanism, and the clutch clutch are all manually operated.

Therefore, the three-roller sheet metal rolling machine with this structure, because the position of the two lower rollers is fixed and is always symmetrical to the upper roller, the remaining straight side of the end of the workpiece that is directly rolled by it is long, so you need to use special tools or Other equipment pre-bends the end to make up for this deficiency.

Because of its simple structure, reliable work, and easy maintenance, it is widely used in other production of medium plate tubes.

Two

The two lower rollers of the sheet metal rolling machine are the driving rollers, which are transmitted by the main motor through the three-stage transmission pair of the arc gear reducer with a ratio of 62.2 to the first-stage open gear pair supported by the lower roller, so that the lower roller The design rotation speed is obtained and constitutes the main transmission system of the machine. There is a brake in the main drive system to achieve rapid braking.

The lifting movement of the upper roller is decelerated by the auxiliary motor through the secondary transmission pair of the auxiliary circular arc gear reducer with a ratio of 12, which drives the worm gear pair installed in the frame to rotate, and the wire sleeve embedded in the wheel rotates to force the connection to the upper roller.The lifting screw rod moves linearly, forming the auxiliary system of the machine. The adjustment of the relative position of the two ends of the upper roller with respect to the lower roller is realized by separately lifting the lifting screw Hodder at the left end after disengaging the clutch on the worm shaft.

The upper roller of the sheet metal rolling machine is the active roller. The main motor drives the upper roller to work through the main reducer and coupling. The function of the lower roller is to provide a certain upward force to clamp the rolled steel plate together with the upper roller to make Sufficient friction is generated between the upper roller and the coiled steel plate, which can drive the steel plate to move when the upper roller rotates. The two side rollers are used to form the required curvature of the roll, so that the sheet can achieve the required purpose.

Three

In the four-roller sheet metal rolling machine we designed, we used the main motor through the main reducer and coupling to drive the upper roll to rotate. For the movement of the lower roller, we put a hydraulic cylinder on each end of the lower roller, and the hydraulic oil in the hydraulic cylinder acts on the piston so that the lower roller can move up and down, so that the steel plate can be clamped and controlled by the hydraulic system. The lifting of the roller and the two hydraulic cylinders keep rising synchronously during the ascending process. There are two side rollers on both sides of the lower roller. The two side rollers are respectively driven by two motors through two single-stage reducers and couplings; the two motors can be controlled separately or simultaneously. The two side rollers It can be tilted along the guide rails of the frame and driven by a worm gear and a screw nut.
