Hydraulic Press Machine JH21
Product details
Hydraulic Press Machine
SPRING’s JH21 series of open type hydraulic presses are suitable for shearing, punching, dropping, bending and shallow drawing work.
MACHINE FEATURES
- The machine body is made of integral steel plate welded structure with high rigidity.
- High precision to meet JIS1 standard
- The crankshaft is placed longitudinally with short pivot distance and good crankshaft stiffness.
- Transmission system is closed inside the body, gears are lubricated by immersion oil.Transmission system is closed inside the body, gears are lubricated by immersion oil.
- Adopts a combination of rigid interlocking dry pneumatic friction clutch-brake, clutch its overall performance, the indicators have reached the level of international advanced products, performance in the transmission torque is greater, the slave inertia is very small, easy to install and maintain.
- Slider is a casting box structure, the high pressure cylinder in the slider is equipped with imported high pressure oil seal, the imported hydraulic overload protector, the action is sensitive and reliable, it can be automatically reset after overloading to reduce the downtime and improve the utilisation rate of the press.
- Slider mould loading height is automatically adjustable (except 25T,45T).
- Adopts hexahedral rectangular lengthening guide rail, high guiding precision, good precision retention.
- Adopts pneumatic balancing device to dynamically balance the weight of slider and upper mould to improve the dynamic accuracy of the press, and its seals are all adopted from Taiwan Hansheng Company.
- Adopts Japanese imported duplex safety solenoid valve to ensure the accurate execution of clutch command.
- Electrical control adopts PLC from OMRON for centralised control, which improves the reliability of the whole machine.
- Adopts cam controller consisting of proximity switches to reliably achieve synchronous detection and monitoring.
- Optional: output shaft, air cushion, slider hitting, automatic feeding and other devices
