Four rolls plate rolling machine operation steps

Four rolls plate rolling machine operation steps

The operating steps of the four roll plate rolling machine mainly include the preparation phase, aligning the plate head, tightening the plate, pre-bending the front plate head of the appropriate length, the coiling process, and checking that the rolled plate meets the requirements. 

Preparation : The operator needs to precisely align the plate head, which can be achieved by skillfully utilizing the front side rolls. Once the heads are aligned, the next step is to lift the lower roll to tighten the sheet and ensure that it remains stable during the rolling process.

Aligning the plate head: The operator needs to skillfully back the front plate head near the cut-off point of the upper and lower rolls, which requires an in-depth knowledge of the machine's performance and the characteristics of the plate.

Tightening the sheet: Lowering the front side rolls while raising the rear side rolls to the proper position is a series of movements that need to be precise and quick to ensure that the sheet does not shift during the coiling process.

Pre-bend the front plate head to the proper length: Drive the work rolls to start rotating and pre-bend the front plate head to the proper length. This step is a critical part of the coiling process and requires the operator to adjust the rotational speed and strength of the work rolls according to the thickness of the sheet, the material and the degree of bending required.

Rolling process: Lowering the rear side rolls while raising the front side rolls is to ensure that the sheet remains smooth throughout the rolling process. During this process, the operator needs to keep a close eye on the rolled sheet and adjust the position and speed of the rolls at any time.

Checking the rolled sheet: When the rear plate head rotates to the vicinity of the upper and lower roll cut points, it marks the completion of the rolling process. At this point, the operator needs to stop the rotation of the work rollers to check whether the rolled sheet meets the requirements.

The whole operation process requires the operator to have rich experience and exquisite skills to ensure the quality and efficiency of plate rolling. In addition, the safety operation procedures of the four-roll plate rolling machine include dedicated management, operators familiarizing themselves with the structural performance and use of the machine, and checking the safety devices before starting the machine to ensure the safety and efficiency of the operation.
