A gravity casting machine completes multiple tilting cycles every day, with mold weight and tilting torque repeatedly acting on the tilting mechanism. Whether the equipment still maintains its initial tilt accuracy after one or two years of use depends on the design and manufacturing level of the tilting shaft system and support structure. As a source manufacturer of foundry equipment, ZMZO Intelligent Equipment pays attention to long-term accuracy retention in the tilting mechanism of its gravity casting machines.
Matching the Tilting Main Shaft with Bearing Span
The tilting main shaft bears the full weight of the mold and the tilting torque. If the shaft diameter is too small or the bearing span is unreasonable, the main shaft may develop slight bending over long-term use, leading to tilt angle deviation. ZMZO's gravity casting machines use a larger-diameter tilting main shaft combined with a reasonable bearing span design to reduce elastic deformation during tilting. This structure helps maintain good angular repeatability even after several years of equipment use.Centralized Lubrication Reduces Wear on Moving Pairs
The lubrication condition of the tilting shaft and bearings directly affects wear rate. When lubrication is insufficient, metal surfaces contact directly, wear accelerates, clearance gradually increases, and vibration may occur at the start of tilting. ZMZO's gravity casting machines use centralized lubrication, supplying oil to each lubrication point at set intervals. Operators only need to periodically check the grease reserve rather than manually greasing each point.Encoder Feedback Maintains Angular Accuracy
Precise control of the tilt angle requires real-time monitoring of the actual position and comparison with the set value. ZMZO'sgravity casting machines are equipped with an encoder on the tilting shaft that continuously feeds back angle signals. The control system automatically adjusts the drive output based on feedback, maintaining tilt angle accuracy through closed-loop control even if mechanical components experience slight wear.Conclusion
Maintaining tilt accuracy in gravity casting machines depends on the rationality of the main shaft and bearing design, the reliability of the lubrication system, and the application of closed-loop control.
