      Structure and characteristics:

      The JH21A series open fixed table press is developed and produced by our company (formerly Shanghai Second Forging Machine Tool Factory) by introducing advanced technology from both domestic and foreign sources

      The universal single axis high-performance press machine has a more complete product structure and has become an increasing production and sales force

      The product is suitable for various stamping process lines such as automated wiring and peripheral product combination punching, material dropping, etc.

      Performance characteristics:

      1. The electrical system adopts a human-machine interface, controlled by the Japanese Omron programmable logic controller (PLC),

      Touchscreen is a leading domestic brand of "Weilun", and the machine tool operates with variable speed drives. The machine tool has emergency stop

      Inching, single and continuous, pre fabricated counting and peripheral equipment connection work operation modes; main

      All electrical components are from the French brand Schneider, with reliable performance.

      2. The clutch dual valve is selected from the Japanese brand "TACO", and the pneumatic two-piece is from the "Yadeke" brand,

      Reliable performance. 3. The body is made of high-quality steel plate CNC cutting and CO2 welded structure, with good overall rigidity and beautiful appearance;

      The body adopts trolley type electric furnace annealing or vibration aging methods to remove stress, with minimal deformation. The crankshaft is placed longitudinally,

      Short pivot distance, compact structure, and reasonable layout. The transmission gear operates immersed in oil in the gearbox, as indicated by the gear gauge

      Surface grinding treatment results in low noise and minimal wear during transmission operation.

      4. Pneumatic friction clutch brake, mechanical interlocking, safe and reliable, low noise, and friction plates are not easily worn; Choose domestic Shanghai "Dingjie" brand clutch or Italian "OMPI" brand clutch; And provide wet clutches according to the special needs of users.

      5. Select imported pneumatic external hydraulic overload pump, which has sensitive response, good stability, and easy maintenance.

      6. The slider guide rail adopts six sided guidance, with a long guide rail and high operating accuracy.

      7. The lubrication system adopts imported electric grease pump for automatic fixed-point lubrication, and is equipped with a progressive distributor for oil supply

      The time and fuel supply are controlled by the PLC system, and automatic alarm indication is given for oil circuit blockage.

      8. The slider mold height adjustment is convenient to use, and it is equipped with a digital mold height indicator with a display accuracy of+0.1mm.

      (Note: Manual adjustment for JH21B-60 and below, electric adjustment for JH21B-80 and above).
