High-precision machine tool design: The mechanical structure of the Dual-Machine Linkage Hydraulic Sheet Bending Machine is one of the keys to determining the processing accuracy. The machine body, worktable, slider and other key components are usually made of high-strength and high-precision materials. The rigidity of the whole machine is ensured through reasonable layout and stable connection. This rigid design can effectively avoid vibration and deformation during the processing process, thereby ensuring the accuracy of the workpiece.
Precision guide rails: The slider and guide rails use high-precision linear guide rails to ensure the stability and accuracy of the slider during movement. The use of precision guide rails can reduce the friction resistance of the slider and improve the accuracy of mechanical transmission.
Servo control system:
The servo control system is the core part of the Dual-Machine Linkage Hydraulic Sheet Bending Machine, and its accuracy directly affects the processing accuracy of the whole machine. The fluctuation of the servo motor when there is no load and the speed is zero should be strictly controlled within a certain range (such as not more than 0.1%) to ensure stability during the processing.
The closed-loop control system can achieve precise angle control, and its accuracy requirement is usually not less than 0.1 degrees per degree, so as to ensure the accuracy of the bending angle.
2. Operation process
Parameter adjustment:
Before using the Dual-Machine Linkage Hydraulic Sheet Bending Machine, it is necessary to determine the appropriate parameters according to the material, thickness and required bending angle of the sheet to be processed. The main adjustment parameters include bending torque, distance between upper and lower molds, bending speed, etc. Reasonable parameter adjustment can ensure stability and accuracy during the processing.
For example, adjust the bending torque according to the material and thickness of the sheet to ensure stability and accuracy during the bending process; adjust the distance between the upper and lower molds according to the thickness of the sheet to ensure that the sheet can pass smoothly and avoid distortion caused by excessive bending.
Operating skills:
During the processing, the operator's proficiency and operating skills will also affect the accuracy. The operator needs to ensure that the plate is flat and without deformation before processing, and arrange the clamping points reasonably to ensure the stability of the plate during processing.
Controlling the operating force is also the key to avoid bending deviation caused by excessive or insufficient operating force.
3. Maintenance
Regular cleaning and lubrication:
Regularly clean the working table, mold and transmission parts of the bending machine to avoid the influence of dust and waste on precision control.
Lubricate the lubrication parts regularly according to the equipment manual to ensure the flexibility and stability of the equipment.
Check fasteners:
Regularly check and tighten the fasteners of each component to ensure the stability and accuracy of the equipment. Loose fasteners may cause vibration and deviation during processing, thereby affecting the accuracy of the workpiece.
4. Other factors
Choice of plate and mold:
The material, thickness of the plate and the shape, size, gap, etc. of the mold will affect the processing accuracy. Therefore, when selecting plates and molds, it is necessary to reasonably match them according to specific processing requirements and conditions.
Quality inspection and feedback:
After processing, the workpiece needs to be inspected for quality, including size, shape, angle and other aspects. Qualified inspection results are an important criterion for ensuring the accuracy of the workpiece. At the same time, feedback and adjustment of processing parameters and operating procedures are made according to the inspection results to continuously optimize the processing accuracy.
In summary, the measures to ensure the accuracy of the workpiece during the processing of the Dual-Machine Linkage Hydraulic Sheet Bending Machine involve structural design, operating procedures, maintenance, and the selection of plates and molds. By comprehensively applying these measures, it can be ensured that the Dual-Machine Linkage Hydraulic Sheet Bending Machine can meet the high-precision requirements during the processing.
