Bending Machine Plate Replacement and Adjustment Methods
Introduction and Background
A bending machine is a widely used equipment in the metal processing industry for bending and shaping various metal sheets. During the processing, frequent plate replacements are often required based on different material, size, and shape requirements. To ensure bending quality and production efficiency, it is crucial to correctly adjust the bending machine parameters during plate replacement. This article will provide you with detailed technical answers regarding the structure, working principle, and plate replacement adjustment methods of bending machines.
Basic Structure and Principle of Bending Machines
Before delving into the plate replacement adjustment methods of bending machines, it is necessary to have a certain understanding of their structure and working principle:
1. Worktable and bending die: The worktable is the main area for placing the sheet, and the bending die applies pressure through the slide system to bend and deform the sheet.
2. Slide system: The slide is the upper moving component that drives the upper die to press down on the sheet through hydraulic or mechanical power.
3. Control system: Modern bending machines are generally equipped with CNC systems, allowing precise adjustment of bending angles, pressure, and slide stroke.
4. Hydraulic system: It provides pressure power to the slide and other moving components.
Key Steps for Plate Replacement Adjustment in Bending Machines
During operation, plate replacement and adjustment require technical expertise. The following are the adjustment steps:
1. Select suitable dies: Before replacing the plate, choose appropriate dies based on the material and thickness of the sheet, ensuring that the width of the lower die opening and the shape of the upper die match the sheet.
2. Adjust slide stroke: Adjust the length of the slide stroke according to the dimensions, thickness, and desired bending angle of the sheet, ensuring that the slide reaches the correct depth when applying pressure.
3. Adjust bending angle: Utilize the CNC system or manually adjust the angle parameters of the slide to set the correct bending angle.
4. Adjust material stop device: Adjust the position of the material stop device according to the dimensions of the sheet, ensuring precise positioning of the sheet.
5. Trial pressure calibration: Before starting the actual bending process, perform trial pressure calibration to check the accuracy of the adjustments and make necessary parameter fine-tuning.
Technical Precautions
1. Safety operation: Ensure that the bending machine is turned off and the slide is in a stopped state during plate replacement and adjustment to prevent accidental damage.
2. Hydraulic system inspection: Regularly check the oil level and quality of the hydraulic system to ensure stable operation.
3. Die maintenance: The die is a core component of the bending process. Regular cleaning and lubrication are necessary to maintain its accuracy and lifespan.
4. CNC system backup: For CNC bending machines, regularly back up bending programs and parameter settings to prevent accidental loss.
Conclusion
Plate replacement adjustment in bending machines is a technical operation that requires operators to have rich experience and technical knowledge. By following a scientific operating procedure and employing the correct technical methods, not only can production efficiency be improved, but the quality of bent products can also be significantly enhanced. Through this detailed technical guide, operators can obtain practical advice on plate replacement adjustment in bending machines, ensuring stable and efficient equipment operation.
