Sewing machine

It is composed of frame, motor driving part, three roll rolling part, plate positioning and electric control system. Complete the cylinder rolling process; JH21-45 cylindrical table press and buckle die.
Brief Introduction of JH21-45 Cylindrical Workbench Press:
Brief introduction of structural performance of condyle
JH21-45 cylindrical table press is one of the new generation general press for sheet metal processing developed by Jiangsu Yangli Group Co., Ltd. in 1990s with advanced technology from Japan AIDA Company. It is suitable for punching and riveting of hub parts. Its structural characteristics are as follows:
The fuselage is welded with integral steel plate and has high stiffness. The angular deformation of fuselage is less than 2 corners.
The crankshaft is longitudinally placed with short fulcrum distance and good crankshaft stiffness.
The transmission system is enclosed in the fuselage and the gears are lubricated with oil.
Using the combined rigid chain dry pneumatic friction clutch - brake, the overall performance and various indicators of the clutch have reached the level of international advanced products, manifested in greater transfer torque, small follower inertia, easy installation and maintenance.
The slider is a casting box structure. The high-pressure cylinder in the slider is equipped with imported high-pressure oil seals. The imported hydraulic overload protector is used. The action is sensitive and reliable. After overloading, the slider can be automatically reset, the downtime can be reduced, and the utilization rate of the press can be improved.
The height of the slider is manually adjusted, and the height of the slider is displayed by the sign.
The hexahedral rectangular lengthened guide rail has high guiding accuracy and good accuracy retention.
The pneumatic balance device is used to balance the weight of the slider and the upper die to improve the dynamic accuracy of the press.
Gt; adopt double safety solenoid valve imported from Japan to ensure the accurate execution of clutch instructions.
Electrical control uses Omron PLC for centralized control, which improves the reliability of the whole machine.
Electronic cam is used to reliably realize synchronous detection and monitoring. JH21 series press is manufactured strictly in accordance with JB/T6580-93 "Accuracy of Open Press" and JB/T6580.1-1998 "Technical Conditions of Open Press". The safety of the whole press meets the requirements of GB17120-1997 "Technical Conditions for Safety of Forging Machinery" and JB3350-93 "Technical Conditions for Safety of Mechanical Press".
The plate positioning device is composed of supporting plate and two side guide plate, which is used to guide the plate when it enters the roll. The guide plate is made of tungsten steel with hardness over HRC60. It can prevent long-term frictional damage on the edge of the plate. The guide plate is fixed on one side and manually adjustable on the other side to meet the requirements of products with different widths.
