I. Rational Workpiece Layout to Avoid Local Overload
1. Even Load Distribution: Welding workpieces should be rotated and placed in different areas of the workbench to avoid long-term concentration on one side or in the center.
2. Controlling Single-Point Stress: Heavy workpieces require distributed support, using multiple support points to prevent excessive local pressure that could cause platform sinking or deformation.
3. Symmetrical Fixture Arrangement: Clamping force should be applied as symmetrically as possible to reduce stress concentration and minor displacement caused by uneven force distribution.
It is recommended to establish a "zone rotation system," dividing the workbench into several zones and changing the main operating zone for each operation to achieve load distribution.
II. Standardizing Operating Procedures to Prevent Human-Induced Damage
1. Prohibit Direct Impact on the Workbench Surface: It is strictly forbidden to use hammers or other hard objects to strike the workbench surface and positioning components to avoid localized dents or hole deformation.
2. Apply Anti-Spatter Liquid Before Welding: Effectively prevents weld slag adhesion, reduces scratch damage during cleaning, and protects the accuracy of the workbench surface.
3. Do not ignite or arc on the platform: Ensure proper grounding to prevent current from flowing through the platform body and causing localized high-temperature damage.
III. Regular Inspection and Accuracy Calibration
1. Conduct accuracy inspection every 3-6 months: Use a level, laser interferometer, or coordinate measuring machine to check flatness and promptly detect minor deformations.
2. Adjust support points to maintain level: Adjust the platform's bottom supports to distribute the load evenly across all support points, preventing uneven loading due to uneven ground.
3. Protective measures are required for long-term inactivity: Cover with dustproof cloth and apply rust-preventive oil to the platform surface, especially easily corroded areas such as T-slots and positioning holes.
IV. Environmental and Load Management
1. Keep away from vibration sources and humid environments: The platform should be installed in a stable, dry location free from strong vibrations to prevent external factors from interfering with accuracy.
2. Control actual load within the rated range: It is recommended that the load not exceed 80% of the platform's rated load, leaving a safety margin for dynamic loads.
3. High-temperature workpieces require the addition of heat insulation pads: to prevent local thermal expansion caused by heat conduction, which could damage the overall structural stability.
