3. Air-operated double–balanced cylinder, the balanced sliding block and the upper die weight can reduce the impact and noise, eliminate the gap between the connecting rod and the sliding block, reduce the impact and abrasion of loaded parts, and enhance and molding precision of the parts.
4. The whole machine has adopted imported PLC centralized control, and imported safety double value control is applied to the gas circuit, to realize inch, single and continuous punching;
5. The key parts such as the slider, guide rail, worktable plate, connecting rod and flywheel are cast with resin sand. Compared with common clay sand casting, the surface roughness and dimensional accuracy are improved effectively;
6. Electrical control is applied to die-filling height for JH21 products of 60 tons or above; high-quality configuration, and all the key components and parts such as pneumatic components, electrical apparatus elements, sealing elements, and buttons are imported.

Advantages of JH21 Series C-frame Fixed Bolster Press

High rigidity, high-precision body, high-precision operation, long life!

1. The body adopts computer 3 d design, after the finite element analysis make optimization, ensuring the rigidity of the body and angular stiffness of C shape
2. The body adopts a welding structure, the use of carbon dioxide gas shielded welding, after welding, check the weld inspection.
3. Make the gear drive box of weld do the oil seal experiments, and ensure the overall tightness of the gear drive box is well.
4. Do the tempering treatment after welding, the surface does shoot blasting to remove oxide skin after tempering (the company has a large space gas tempering furnace and blast room), further eliminating the internal stress; and improving the machining precision of the body.
5. The body adapts to advanced PAMA machining center, one-time clamping processing, ensures the dimensional accuracy, the accuracy of form and position in the processing of the body, and greatly improves the motive precision and the service life of press.

The world patent wet clutch, high performance, high efficiency, low maintenance cost.

1. First wet clutch in our country. Use Japanese advanced technology, high performance, high efficiency, low inertia, high torque, no dust, etc. It has been the great advantage of World products.
2. Adopt an imported sealing element, which has very well thermal stability, particles by normal abrasion of the friction plate can be carried out by regular oil, with no bad effect on products, to ensure that the overall clutch working performance is stable.
3. Adoptoilbath lubrication and form oil slick between friction plates, friction loss small, long service life and low maintenance cost, and adopt world advanced assembly technology, make the temperature in its work can be controlled to a minimum value, has reached the leading level in the industry.
4. World wet clutch warranty period is three years.
5. After completion of all the flywheel and clutch assembly must be carried out to the dynamic balance and static balance experiments, to guarantee stable operation.

The slider component

1. Three connecting rod structures, which can reduce the cost of maintenance and replacement, the connecting rod is made of high-quality ductile iron castings, and makes normalized processing, improving the strength of parts;
2. All screws adopt nitride treatment, increasing the screw surface strength, increasing the screw surface anti-seizure ability, and greatly reducing the risk of screw and killed.
3. JH21-60~400 products use the die height-adjusted motor, reducing the labor intensity of operation. Make the operation convenient, height of mode mechanical digital display.
4. Hydraulic overload protection device for the whole system.
5. Configuration of high-quality copper-bearing bush and turbine, reducing abrasion loss; and increasing the service life.

The power system and transmission components – high efficiency, high accuracy and stability.

1. The standard Siemens motor series (Bei), Vander-Waals forces (a domestic famous brand), has the characteristics of high efficiency, high protection, low energy consumption, and cost effectiveness.
2. The slider, guide rail, work table, connecting rod, female connector and other parts using lost foam cast, compared with the common clay sand casting, improves the dimensional accuracy level 2-3, makes the composite clearance tiny, greatly improves the service life of the die.
3. High quality 40Cr material, forging crankshaft, the rolling process after processing, make its surface hardness, finish degree further promote, to ensure long-term work wear resistance of the crankshaft.
4. The slider uses the side guide in the whole structure, a long guide rail, and guide surface bronze panels and guide precision is high.
5. Configuration of pneumatic double balance cylinder, balance weight of the slider and the upper die, reduce the impact, reduce noise, eliminate the clearance between the sliders and connecting rod, reduce loss; improve efficiency and service life of the press.
6. The flywheel and the clutch assembly adopted the excellent design of dynamic balance, the high-speed stamping to minimize the vibration and noise, and can extend the service life of mold.

The oil pipeline and airline – the layout is clear, safe, and reliable

1. The whole system adopts hydraulic overload protection device, overload emergency stop automatically, and can effectively protect the press and mould, the sliding block is not a burden to ensure the safety of the operation.
2. The use of electric pump thick oil forced lubrication system, oil alarm stop function, ensure the machine runs smoothly.
3. The gas path chooses import safe double valve, sensitive and reliable action; can realize point move, inching, single and continuous punching, ensure the safety of the press.

The fine configuration, more complete, more practical

1. The touchscreen interface, simple operation, all the parameters isclear.
2. Above 60t tonnage is adopted mould height byelectric regulating,easy to use, reduce the labor intensity
3. Can be customized according to user needs, equipped with light curtain, frequency control of motor speed, air cushion device, automatic feedingthe output shaft, etc., can matchesvarious kinds of automation equipment.
