Plate Rolling Machine China

We are a professional plate rolling machine manufacturer with over 10 years of industry experience. Today, we would like to introduce the classification of three roll plate rolling machines:

A plate rolling machine (also known as a circular rolling machine) is a machine tool used for continuous point bending of metal sheets. According to its structure, it can be divided into two roll plate rolling machine, three roll plate rolling machine, and four roll plate rolling machine. Today, we will mainly introduce the classification of three roll plate rolling machines.

The three roll plate rolling machine is divided into mechanical and hydraulic types.

1, Mechanical three roll plate rolling machines can be divided into symmetrical and asymmetrical types.

(1)Mechanical three roll symmetrical type

Performance characteristics:

The structural form of the mechanical three roll symmetrical plate rolling machine is a three roll symmetrical layout. The upper roller is located at the center symmetrical position of the two lower rollers, and the vertical lifting motion is achieved through the transmission of a screw, a nut, and a worm. The two lower rollers are meshed with the lower roller gear through a reducer to perform rotational motion, providing the required torque for the sheet rolling process.

limitations:

The drawback of this type of rolling machine is that the pre bending operation at the end of the sheet cannot be completed by the equipment itself, and other auxiliary equipment needs to be used for implementation.

(2) Mechanical three-roll asymmetric type

Structure and working principle:

Mechanical three-roll asymmetric type plate rolling machine adopts three-roll asymmetric structure layout. Among them, the upper roller assumes the main drive function. The lower roller has vertical lifting function, which is aimed at firmly clamping the plate to be processed, and the lower roller meshes with the upper roller gears through its gears, which together with the upper roller constitutes the main transmission system. The side rolls have an inclined lifting movement, which gives the machine the dual function of pre-bending the sheet and rolling a round shape.

Advantageous features:

The structure of this type of plate rolling machine is compact, outstanding in operation convenience and maintenance simplicity, which can effectively reduce the operator's work intensity, shorten the maintenance cycle, and improve the overall production efficiency.

2, Hydraulic

The core structure of hydraulic three-roller symmetric plate rolling machine is that the upper roller has the function of vertical lifting and lowering, and this lifting and lowering action is realized by the hydraulic transmission system. Specifically, the hydraulic oil in the hydraulic cylinder exerts force on the piston rod, driving the upper roller to complete the vertical displacement. The lower roller assumes the task of rotary drive and provides the necessary torque for the plate rolling process by means of the meshing transmission of the output gears of the speed reducer. The lower roll is equipped with adjustable rollers, which are used to support the plates and ensure the stability of the rolling process. In addition, the upper roll adopts a drum-shaped design, and this special shape can effectively improve the straightness of rolled products, which is especially suitable for the manufacturing of ultra-long sizes and tanks with various cross-sectional shapes.

The coiler is of upward symmetrical construction and is capable of accurately rolling sheet metal into round, curved and tapered workpieces within a certain taper range. In terms of the operating mechanism, the two lower rolls are responsible for providing the main driving force as the active rolls, while the upper rolls work in tandem as the driven rolls. The application areas are extremely wide and cover a number of important industries such as shipbuilding, boiler manufacturing, aviation industry, hydroelectric engineering, chemical production, metal structure processing and machinery manufacturing.

This machine is mainly used to realize the bending and deformation processing of metal plates, which can not only efficiently roll round and curved workpieces, but also complete the production of conical workpieces within a certain process range. At the same time, this model has the function of plate end pre-bending, which greatly improves the convenience and accuracy of processing. In the structural design, the two lower rollers as the active roller can move horizontally, while the upper roller as the driven roller can move up and down, the movement is divided into mechanical and hydraulic two kinds, and the drive shafts are connected with universal couplings to ensure the smoothness and efficiency of the transmission process, to adapt to the complexity and diversity of the processing needs.
