What is the process of plate rolling machine?

In the modern metal processing industry, plate rolling machine process, as an important molding method, is widely used in the manufacture of industrial containers, tanks, pipes and pressure equipment. As the core equipment, plate rolling machine, through a series of precise process, will be flat metal plate molded into cylinders, cones or other curved shapes. In this article, we will introduce the process of plate rolling machine and its key points in detail, to help you better understand this mechanical product.

1. Overview of the process of plate rolling machine

(1) Preparatory work: before the operation of the rolled plate, you need to check whether the equipment of the rolled plate machine is running normally. At the same time, you also need to check the quality and size of the sheet metal to meet the requirements.

(2) Upper clamping material: Place the metal sheet to be rolled on the plate rolling machine and clamp it using the upper clamping device on the plate rolling machine. Make sure the material is firmly fixed on the plate rolling machine. Prevent loosening or falling off during operation.

(3) Setting parameters: Set the parameters of the plate rolling machine according to the requirements of the rolled product. These parameters include coiling speed, tension control, coiling diameter, and so on. Ensure that these parameters are set to meet the requirements of the product, and to ensure the safe operation of the plate rolling machine.

(4) pre-bend: at the beginning of the rolled plate, due to the two edges of the plate can not fully contact the upper roll of the plate rolling machine, so there will be a remaining straight edge. The purpose of pre-bending is to bend this part of the remaining straight edge to the required radius of curvature first, in preparation for the subsequent rounding.

(5) centering: in order to ensure the accuracy and stability of the rolled plate process, it is necessary to center the plate before the roll bending operation. That is, adjust the position of the plate, so that its center line and the roll axis of the plate rolling machine to maintain parallel, so as to avoid the phenomenon of distortion in the process of bending.

(6) roll round: when the plate after pre-bending and centering, you can start the roll round operation. In this process, the upper roll of the plate rolling machine will be continuously pressed down and rotated, so that the plate is gradually bent into a round or other predetermined shape.

(7) Rounding: After the rounding is completed, in order to further improve the quality and precision of the product, it is usually necessary to carry out the rounding operation. This step is mainly through the adjustment of the roller position and pressure of the plate rolling machine, the plate for subtle correction and adjustment, so that its curvature is more uniform and consistent.

(8) Coiling the finished product: when the coil reaches the required diameter or length, the plate rolling machine will automatically stop. At this time, the coiled metal sheet will be removed from the plate rolling machine and inspected. For the unqualified quality of the coiled product, it needs to be reprocessed or discarded.

(9) Cleaning and maintenance: During the shutdown period of the plate rolling machine, the plate rolling machine needs to be cleaned and maintained. Cleanup work includes cleaning up the surface of the plate rolling machine waste, keep the equipment clean. Maintenance work includes lubrication lubrication parts, check the wear and tear of the equipment.

2. Analysis of the process principle of plate rolling machine

The core of the process of plate rolling machine is the “three points into a circle” principle. The upper roller and the two lower rollers form a three-point force, through the relative position of the roller adjustment and pressure, so that the metal plate in a controlled state gradually produce plastic bending.

-When the roller spacing and pressure change, the bending radius of the plate is also adjusted.

-Through continuous rolling, the plate can form a smooth and regular curved surface structure.

During the operation of the rolling machine, the parameter settings and operation sequence of each step need to be strictly controlled to ensure that the final product can meet the predetermined quality requirements.

The process of rolling machine is interlocked, each step is directly related to the quality of the final product. With the continuous upgrading of technology, plate rolling machine not only in the molding accuracy greatly improved, but also in the automation and intelligence to show great advantages. In the future, the plate rolling machine process will play an important role in more high-end equipment manufacturing and emerging industries, and continue to be an indispensable key link in the field of metal processing.
