I. What is plate rolling machine calibration?

Plate rolling machine calibration is a critical process designed to adjust and verify the various components of the plate rolling machine to ensure its accuracy and consistency during the metal processing process. Specifically, this calibration work involves inspecting, adjusting and calibrating the various mechanical, electronic and hydraulic systems of the plate bending machine to ensure that they work as expected and meet specific technical specifications and safety standards.

During the calibration process of the plate rolling machine, the following aspects are usually involved:

Mechanical component adjustment:

This involves adjusting the position and spacing of the rollers to ensure that the sheet metal is bent correctly during the curling process. Additionally, it may involve calibrating the position and pressure of the press and side rollers to ensure that the sheet is properly supported and pressed.

Electronic system calibration:

Modern plate rolling machines are usually equipped with electronic control systems to monitor and adjust various parameters during the plate rolling process. During the calibration process, these electronic systems need to be inspected and calibrated to ensure their accuracy and reliability.

Hydraulic system adjustment:

The hydraulic system plays an important role in the operation of the plate rolling machine, controlling the movement of the rollers and the application of pressure. Calibrating a hydraulic system involves checking hydraulic pressure, flow, and leaks to ensure the system is working properly.

Safety function inspection:

In addition to the calibration of mechanical and electronic systems, the safety functions of the plate rolling machine, such as emergency stop buttons, safety shields, etc., also need to be checked to ensure the safety of operators and equipment.

II. Why is it necessary to calibrate the plate rolling machine?

The accuracy of the plate rolling machine directly affects the quality and precision of the final product. An uncalibrated plate bending machine can cause product size inconsistencies, shape deviations or production interruptions, impacting production efficiency and customer satisfaction. Here is a more detailed explanation:

Ensure product quality and accuracy:

The accuracy of the plate rolling machine directly affects the quality and accuracy of the final product. By regularly calibrating the plate rolling machine, you can ensure that the metal sheets produced have the correct size, shape and surface quality, thereby avoiding product defects caused by dimensional deviations or irregular shapes.

Ensure production consistency:

Calibrated plate rolling machines produce consistent processing results, whether in batches or single-piece production. This consistency is critical to meeting customer requirements, maintaining brand reputation, and increasing productivity.

Reduce scrap rates and costs:

An uncalibrated plate bending machine may cause product size inconsistencies or shape deviations, which in turn increases scrap rates and rework costs. By ensuring the accuracy and stability of your plate rolling machine, you can reduce scrap rates and reduce costs associated with substandard products.

Increased productivity:

Calibrated plate rolling machines are often able to operate at higher speeds and efficiency because they are able to perform machining tasks more accurately, reducing the need for interruptions and adjustments, thereby increasing productivity.
