Hydraulic three roll pyramid cone rolling machine manual

2025 06/23

Structural Diagram
Host Machine Structure:
Top Roll: Hydraulically driven, vertically adjustable (pre-bending function).
Bottom Rolls: Independently controlled by left/right hydraulic cylinders for asymmetric tilting.
Frame: High-strength welded construction with reinforcement ribs.
Hydraulic Power Unit:
Variable displacement pump, relief valve, synchronizing valve, oil cooler.
Electrical Control System:
PLC controller + HMI touchscreen (e.g., Siemens S7-1200).
Operation Procedures
Cone Rolling Steps
Parameter Setting:
Input cone parameters on HMI: Small-end diameter, Large-end diameter, Cone length, Plate thickness.
System auto-calculates bottom roll tilt angle:
Bottom Roll Tilting:
Raise left bottom roll (corresponds to small end).
Lower right bottom roll (corresponds to large end).
Plate Centering:
Activate centering device to align plate centerline with roll axis.
Edge Pre-bending:
Lower top roll;  roll plate ends by 1/3 revolution each to eliminate straight edges.
Continuous Cone Rolling:
Engage main drive;  top roll rotates plate while monitoring cone formation.
Precision Calibration:
Check curvature with cone template (accessory);  fine-tune bottom roll height.
