How to use plate rolling machine?
The working principle of the plate rolling machine involves the movement of the work rolls through external forces such as hydraulic pressure and mechanical force, which allows the sheet to be pressed or rolled into shape.
Through the rotation movement and positional changes of work rolls with different shapes, it’s possible to produce oval parts, arc parts, cylindrical parts, and other shapes. Let’s take a closer look at the steps involved in using the roll bending machine.
Preparation before using the roll bending machine
Each part of the machine must be inspected and found to be in proper working condition, with no loose fastening screws. The brake must be functioning properly and securely.
The distance between the rollers must be adjusted precisely based on the thickness of the plate, and the machine must not be operated beyond its capacity. Workpieces with mechanical properties that exceed the specified limit cannot be rolled.
Precautions in operation of plate rolling machine
The workpiece should be placed securely, and the start-up operation should be performed once, with clear signals and specified commands.
Do not place your hand on the rolled steel plate and avoid using the inspection model. The inspection model should only be used for rounding after shutting down.
When the workpiece reaches the end of the steel plate, leave a sufficient margin to prevent the workpiece from falling and causing injury.
It is prohibited to stand on the workpiece or check the roundness of the rolled cylinder during the operation of the rolling machine.
When rolling thick and large diameter cylinders or workpieces with high material strength, reduce the number of moving rolls and perform multiple rolls.
When rolling narrow cylinders, they should be rolled in the center of the rolls.
Once the workpiece enters the rolls, prevent hands and clothing from getting caught in the rolls.
Precautions for shutdown of plate rolling machine
If any abnormal noise is detected during the operation of the machine, immediately stop the machine and inspect it for adjustments and repairs.
Turn off the switch and disconnect the power.
After shutting down, place the workpiece in the designated location.
These are the steps for using the roll bending machine.
During the use of the machine, it is important to follow these steps to prevent problems during operation.
Tips for using plate rolling machine
The following are tips to keep in mind while using the plate rolling machine:
Regularly lubricate the machine as outlined in the lubrication diagram, adding oil to each oil cup and manual lubrication point as needed.
If you hear any irregular noises or experience any abnormal impacts during operation, immediately shut down the machine for inspection.
Before turning on the power, check the positive and negative directions of the lower roll and the lifting movement of the upper roll for any abnormal blockages.
Follow the plate bending machine’s processing procedures and operating methods strictly during operation, and be cautious when the upper roll rises and falls to a certain position.
All personnel must coordinate and follow the command of the rolling supervisor, and it is forbidden to start the machine without a password.
When the main drive is shut down, the upper roll can be lifted, and the tilting reset of the overturning bearing and upper roll can be tilted.
Take care to prevent your hands from getting trapped between the steel plate and roller during the rolling operation of large pipes.
When using a crane to lift the steel plate or drum, be careful not to collide with the machine.
These are the precautions to keep in mind when using a roll bending machine.
Maintenance of plate rolling machine
Fill all oil cup lubrication and manual lubrication points as required according to the provisions in the machine’s lubrication diagram.
The plate is rolled according to the parameters specified by the rolling machine, with a thickness of 20mm and a length of 2500mm, and a yield limit of less than 250 MPa.
Upon turning on the power, check that the lower roller moves forward and backward smoothly and that the upper roller moves up and down without any abnormal jamming.
Strictly follow the plate processing procedures and operation methods. Pay close attention to the equipment’s operation when the upper roll is lifted to the limit position.
Once the main drive stops, the upper roll can be lifted, the turning bearing can be reset, and the upper roll can be tilted.
If any irregular noise or impact is noticed during the operation of the bending machine, stop the inspection immediately.
During operation, all personnel should coordinate and follow the command of the roll panel supervisor. It is forbidden to start the machine without a proper password.
Be cautious to prevent your hands from getting pressed by the steel plates during the plate bending machine operation and avoid rolling the steel plates with your hands.
When lifting steel plates or drums with a crane, take care to not collide with the machine. After rolling, clean the finished materials, maintain the equipment, and turn off the power promptly.
