The Machine of Whole structure and Characteristics
1. JH21 Series High Precision Presses is for cutting, punching, blanking, bending and light stretching work.
2.C-Type Steel-welded frame, high rigidity and less deformation Compact,wide body frame eliminating vibration for improved ide life and machine.
3. Rigid construction guarantees exact die mating,Six-side long rectangle guides of the slide with high moving precision and high accuracy, extending the service life of the die.
4. Highly advanced, rigidly supported gears, operate in oil bath without any noise saves space, reduces, shaft deflection, increases gear life.
5. High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.
Transmission control and brake systems:
1. The Press adopts the low inertia combined dry pneumatic friction clutch and brake from OMPI, Italy, Smoother press performance, easier maintenance, to ensure reliable safety and flexible action,Iow noise, long service life.
2. Driving gear is installed into the frame and gear is immersed in oil reservoir. Customer could choose Electromagnetic governor. which is stepless speed regulation within a certain range and enlarge the area of craf.
3. The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.
4.PLC from Omron electrical control system allows various auto-equipment reprogrammed accord-lng to different requirements and perform various functions,to ensure high reliability and high adaptability,
5. Use adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.
6. Machine is with both hands button and foot switch to achieve continuous, single and inching practices.
7. Auto grease lubrication system,easy stroke adjustment mechanism increases press versatility tremendously.
8. Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;
9. The press adopts cam controller which be combined with proximity switch (Schneider) which will realize the synchronous detection and monitoring reliably.
Application
1. Suitable for blanking, punching, forming, bending,stretching and other achieve shallow cold stamping process.
2. Widely used in electrical appliances, vehicles, tractors, agricultural machinery, mining machinery, hardware tools, machinery manufacturing and other industrial fields.
Structure
1. Welded steel fuselage, good stiffness, more stable accuracy.
2. Crankshaft longitudinal discharge, compact structure, beautiful appearance.
3. Die height realize electrically adjustable, digital display to adjust the height.
4. Slider rectangular hexahedron longer rails, with bronze liner, high guiding precision.
5. Combined pneumatic friction clutch brake, smooth engagement, sensitive action.
6. Press down type safety device, ensure the machine overload safety.
7. The slide block is provided with lifting balance cylinder, to achieve the balance block linkage.
Features
1. Using electronic fuel pump, reliable lubrication, digital clarity.
2. The slide block can jog, stop motion emergency, operation more safety.
3. Gas circuit adopts double valve control, sensitive action, press the safety standard.
