Sheet Metal Rolling Machine

A sheet metal rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape. It can be also called a “roll bending machine”, “plate bending machine”, " plate rolling machine" or “rolling machine”.

Manufacturing companies use the metal rolling machine to create different finished metals for commercial applications. Having the right equipment in the machine shop to perform metal forming and metal fabrication is essential for manufacturing high-quality products. Plate rolls transform flat sheets of metal into finished products while angle rolls (also known as profile rolls) bend bar stock and angle iron into round forms. As a professional rolling machine manufacturer and rolling machine supplier in China, Boslaser is ideally positioned to supply this market segment with the utmost in productive and sophisticated sheet metal rolling machinery available today.  

Boslaser provides plate rolling machines, which are the perfect companions for sheet metal industries. These sheet metal roller for sale are available in different models with exclusive specifications developed to meet different industrial workshop requirements and the concerned load of work materials. As a top 10 rolling machine manufacturer in China, Boslaser's plate rolling machine for sale has a strong structure that withstands bending operations when higher work material load is fed. The components of plate rolling machine are made of heavy-duty fabricated steel, the fabrication supports for longer performance and durability without much need for maintenance and also to withstand strain at the time of overloads.

As the name suggests, sheet metal rolling equipment is used for rolling sheets and strips in the metal fabrication industry. These machines come in three roller or four roller designs, depending on how you want to roll, bend, and cut the metal sheet. 


3 roller sheet metal rolling machine

3 roller bending machine work by pinching the metal between two rolls and curving it as it comes in contact with a back forming roll.  When rotation of the rollers is activated, the sheet exits at a given radius. When a cylinder is completely rolled, the sheet is extracted from the top roll. This curves the metal workpiece into a cylindrical form, where it is welded together to produce a cylinder. 

In most applications, these sheet metal roller machines require removal and reinsertion of the sheet to prebend both ends. Machines generally are equipped with some type of top roll release mechanism that allows for the cylinder’s extraction. This extraction is accomplished with the help of a forward-tilting or forward-releasing top roll or a removable end yoke. The third roll (the forming roll) can adjustable. With a manually opened or hydraulically moved to drop hinge, the end of the top shaft is opened to allow removal of the finished workpiece, especially a completed tube shape. 


4 roller sheet metal rolling machine

4 roller bending machine has an additional roller underneath the top roll, which constantly pinches the plate during rolling. 4 roller bending machine has a slight advantage in cycle time because they permit the pre-bending of the leading edge, rolling the cylinder body, and finishing off the trailing prebend, all while rolling in the same direction. 4 roller plate rolling machine generally is the only equipment with NCs or CNCs because the fourth roll provides constant pinching action, minimizing the chance for slippage. Automatic controls use an encoder to track the movement of the plate through the machine. If the plate slips, the bending roll movements will be out of synch with the rolling movement.


Main parts of sheet metal rolling machine


1. Working rollers: roughcast roller--- forging--- annealing--- peeled--- flaw detection--- rough machining--- quenching and tempering treatment--- flaw detection again--- semi-finish machining--- finish machining

2. Large forgings: cylinder body, gear

gear shaft: roughcast-forging-surface inspection-roughing-flaw detection-heart treatment-semi-finishing-finishing

3. Welding structure: racks, base, gearbox cover: eliminating internal stress treatment.

4. The electric control parts: the bending speed of the main transmission part is 5.5m/min, controlled by gearbox and brake through the electric motor

The advantages of sheet metal rolling machine


1. This sheet metal rolling machine can roll form metal roofing sheet. After roll formed by this roll forming machine, the surface will be very smooth and beautiful without any scratch on the surface.

2.Rollforming process: uncoiler, roll forming, forming step effect, cut to length.

3. High strength gears for long durability.

4. Comfortable excentric clamp system and easy operation.

5. Precision ground cast iron roller


The operation and maintenance procedures


1. According to the stipulations in the machine lubrication diagram, refuel the lubrication and artificial lubrication points of each oil cup as required.

2. According to the parameters specified by the coiling machine, the thickness of the coil is 20mm, the maximum length is 2500mm, and the yield limit of the coiled material is less than 250Mpa.

3. After the power is turned on, perform the upward and downward movements of the lower roller in both directions and the upper roller, and check whether there is an abnormal stuck phenomenon in each movement.

4. strictly according to the coil plate processing procedures and operating methods to operate, in the upper roller up and down to the limit position, we must pay great attention to the safe operation of the equipment.

5. When the main drive is stopped, the lifting and lowering of the upper roller can be performed, and the tilting of the bearing and the lifting of the upper roller can be reversed.

6. In the course of operation, if irregular noises, impacts or other abnormal phenomena are found, check the machine immediately.

7. All personnel in the operation should coordinate with each other and obey the conductor's command. There is no password and it is forbidden to start the machine.

8. When the coiling operation is carried out, the hand must be pressed against the steel plate and rolled together with the steel plate.

9. Take care not to collide with the machine when lifting the steel plate or reel with a crane.


After the coil board is finished, it is necessary to clear the site after the completion of the work, and do a good job of maintenance of the equipment, and turn off the power in time.
