Principle of Plate Rollers
The principle behind the operation of a plate bending machine is rooted in hydraulic mechanics and precision engineering. In a symmetrical plate rolling machine, the upper roller moves vertically at the midpoint between two lower rollers, driven by hydraulic pressure exerted on the piston within the cylinder. This hydraulic force, facilitated by hydraulic oil, is regulated to control the movement of the upper roller.
As the upper roller descends, the main reducer’s final reduction gear drives the two lower rollers into rotary motion, generating torque essential for rolling the metal plate. The metal sheet, in a flattened state, is fed between the three work rolls—comprising two lower rollers and one upper roll. Through a combination of the upper roller’s pressing force and the lower rollers’ rotational movement, continuous bending occurs.
This bending process induces plastic deformation within the metal sheet, characterized by compression deformation on the inner layer, retention of the middle layer’s shape, and stretch deformation on the outer layer. As a result, the metal sheet gradually transforms into the desired shape, whether it be a cylinder, cone, or other forms required for various applications.
Despite its efficiency, the hydraulic three-roller bending machine has limitations, particularly regarding the pre-bending of the plate’s end, which often necessitates additional equipment for assistance.
Plate rolling machines excel in handling large-scale bending tasks, especially those involving thick plates of 50mm or more. To enhance precision and overall machine performance, some models feature a row of fixed rollers added to the bottom part of the lower roller. This addition serves to reduce the span between the two rollers, thereby improving the accuracy of the resulting workpiece.
How To Choose A Proper Plate Rolling Machine
Determine your Application Requirements
Begin by clearly outlining your application requirements when selecting a plate rolling machine. Here are some crucial factors to consider:
Plate Thickness and Width:
Start by determining the maximum and minimum plate thickness and width typically involved in your projects. This data will guide you in determining the necessary capacity and size specifications of the machine.
Material Type
Identify the primary types of materials you work with, such as steel, aluminum, or stainless steel. Different plate rolling machines may excel in handling specific material types more effectively than others.
Bending Radii and Shapes:
Evaluate the range of bending radii and shapes required for your projects. Determine whether the machine needs to handle simple curves or complex profiles. This assessment will impact the machine’s capabilities, including the number of rolls and their configurations.
Evaluate Machine Types
There are different types of plate rolling machines available, each with its advantages and limitations. Evaluate the following options to determine which one suits your needs:
- Three-Roll Plate Bending Machine: This traditional machine features three rolls, with the top roll providing the primary force for bending. It is suitable for simpler bending applications and is relatively cost-effective.
- Four-Roll Plate Bending Machine: The four-roll machine incorporates an additional pinch roll, offering enhanced precision and control during the bending process. It is ideal for complex bending operations and provides superior accuracy.
- Variable Geometry Plate Rolling Machine: These machines have the capability to adjust the distance between the top and bottom rolls, enabling the bending of conical or variable curvature shapes. They are suitable for specialized applications requiring high flexibility.
Consider Machine Specifications
Once you have determined the machine type, evaluate the following specifications to ensure they align with your application requirements:
- Capacity: Consider the maximum plate thickness and width the machine can handle. Ensure that it can accommodate your typical project sizes while leaving room for future expansion.
- Roll Diameter: The roll diameter determines the machine’s bending capacity. Larger roll diameters allow for bending thicker plates and achieving tighter radii. Assess whether the machine’s roll diameter meets your bending requirements.
- Drive System: Evaluate the machine’s drive system, which powers the rolls’ rotation. Opt for machines with reliable and efficient drive systems that ensure smooth and synchronized movement.
- Control System: Consider the control features and capabilities of the machine. Advanced control systems allow for precise adjustment of parameters such as roll pressure, speed, and material positioning, enabling better accuracy and repeatability.
Assess Machine Build Quality and Durability
Investing in a plate rolling machine is a significant decision, so it is crucial to assess the machine’s build quality and durability. Look for machines constructed with robust materials, such as high-quality steel, to ensure long-term reliability and stability. Consider the reputation and track record of the manufacturer to ensure they have a history of producing reliable and durable machines.
Evaluate Safety Features and Support Services
Safety should always be a top priority in any manufacturing environment. Assess the machine’s safety features, such as emergency stop buttons, safety interlocks, and guards, to ensure they meet or exceed industry standards. Additionally, consider the availability of technical support, training, and after-sales services provided by the manufacturer or supplier.
