Product Description

JH21 Series C-frame Fixed Bolster Press

Details:
1.The JH21 C-frame single crank press own high rigidity, high-precision body, high precision operation, long life! The frame adopts welding structure,do the tempering treatment and shoot blasting to remove oxide skin, further eliminate the internal stress; Adapts world advanced PAMA machining center, one-time clamping processing to ensure the dimensional accuracy. 
2.The clutch warranty period is three years. Adopt imported sealing element to get the thermal stability
3.The three connecting rod structure, which can reduce the cost of maintenance and replacement.
4.The whole system adopts hydraulic overload protection device,overload emergency stop automatically, imported safe double valve, and can effectively protect the press and mould.
5. Can be customized according to user needs, equipped with light curtain, frequency control of motor speed, air cushion device, automatic feeding the output shaft, etc., can matches various kinds of automation equipment.

Applications:
---Widely used in stretching, bending, engraving, flattening and trimming processes.

Features:
A. High -quality steel plate welded body, all processed by tempering and shot blasting, with good rigidity and stable precision;
B. Longitudinally set bent axle, with compact structure, and the bent axle is processed by rolling ,with good smoothness and flexible rotation; rectangle six-face lengthened guide rail, the guide surface is bronze panel and with high guiding precision.
C. Air-operated double -balanced cylinder, the balance sliding block and 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.
D. 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;
E. The key parts such as 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;
F. 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.
