The thread rolling machine body is cast in one piece of HT250 steel, while the fixed roller base (fixed head) and movable roller base (movable head) are both cast in one piece of QT450 steel. After machining the mounting surfaces, assembly is performed to ensure the overall rigidity of the equipment meets production requirements. The transmission system utilizes large-module spur and helical gears to ensure sufficient torque.
The transmission system should utilize large-module spur and helical gears to ensure sufficient torque.
III. Hydraulic System
1. The hydraulically driven rolling force is stable and capable of continuous operation.
2. The rolling cylinder ensures sufficient hydraulic pressure to complete the thread rolling of the product.
3. The rolling cylinder utilizes two sets of hydraulic cylinders arranged in parallel along the axial direction of the rolling axis. This ensures that during radial rolling, the active and passive rolling axes remain parallel under load.
Multiple sets of hydraulic cylinders ensure synchronized advance and retraction during operation.
4. The rolling cylinder stroke is adjustable and features a mechanical position lock.
5. The hydraulic system is equipped with a radiator with sufficient heat exchange capacity.
IV. Rolling Functions
1. The equipment provides both axial and radial rolling functions.
2. The equipment features roller angle adjustment to meet the requirements of axially rolling long screws. A corresponding rotary plate angle indicator scale is provided to facilitate angle observation and recording during adjustment. 3. The equipment features roller zero-angle adjustment for easy roller adjustment and prevents thread rot.
V. Lubrication System
1. The guide rails are equipped with a manual pump oil lubrication system.
2. The thread rolling wheel is equipped with a lubrication and cooling system.
VI. Operational Functions
1. Automatic, manual, and foot-operated programs are available.
2. The spindle speed has high and low speed selectable functions.
3. The spindle has forward and reverse rotation functions.
4. The spindle has an independent stop function.
5. The rolling system has working feed timing and rear position dwell timer functions.
6. The hydraulic system and cooling system should be able to be started and stopped independently.
7. The electrical control system has an emergency stop function.
