How to use a Hydraulic 4-Roll Plate roller

Using a hydraulic 4-roll plate roller with pre-bend involves several steps:

  1. Preparing the machine: Before using the machine, ensure that it is properly installed and securely anchored to the floor or foundation. Check that all components are in good working condition and that the rollers are clean and free from debris.

  2. Setting the pre-bend: Adjust the position of the top and bottom rollers to create the desired pre-bend. This involves adjusting the distance between the rollers and the pressure applied by the hydraulic cylinders.

  3. Loading the plate: Position the metal plate between the bottom rollers with the pre-bend section at the appropriate location.

  4. Starting the machine: Power on the machine and activate the hydraulic cylinders to start the rolling process. The plate will begin to bend around the rollers.

  5. Adjusting the rollers: Make any necessary adjustments to the position and pressure of the top and bottom rollers to ensure a smooth and consistent bend. This may involve slowing down or stopping the machine to make adjustments.

  6. Repeating the process: Continue rolling the plate until the desired shape is achieved. This may involve several passes through the machine, adjusting the pre-bend and roller positions as necessary.

  7. Unloading the plate: Once the plate has been fully rolled, remove it from the machine and inspect it for any defects or imperfections.

It is important to follow all safety guidelines and wear appropriate personal protective equipment (PPE) when using a hydraulic 4-roll plate roller with pre-bend, as the process can involve high levels of force and pressure.
