For more information, please visit our website.

The JH21-250 is a 250-ton C-frame press designed specifically for the stamping of auto parts. This versatile eccentric press is well-suited for a variety of stamping parts production. It can be integrated with a servo roller feeder and decoiler system to function as an automatic stamping press line. The press offers multiple operational modes, including inching, single strokes, and continuous strokes. The motorized slide adjustment system and digital shut height indicator make it easy to align the die accurately.

Features of the 250 Ton C Frame Press Machine

Our 250 Ton C Frame Press Machine comes equipped with a robust transmission system that includes a flywheel, dry clutch brake, and gear shaft. The main components include the crankshaft, connecting rod, hydraulic overload protection (HOLP), balancer, adjusting nut, and the frame. The main motor and bolster round out the primary setup, providing excellent power and stability. The hydraulic overload protection ensures the machine's longevity and the operator's safety.

The press also features a convenient slider with a mechanical shockproof foot system, making it highly efficient and reliable for high-volume production runs. The electrical slider adjustment devices, along with digital die height indicators, offer enhanced operational precision. This ensures minimized deflection and high accuracy, resulting in longer tool life.

Benefits of the 250 Ton C Frame Press Machine

The frame of the press is constructed from high-strength steel, significantly reducing deformation during operation. The slide rails employ high-frequency quenching technology, achieving a hardness of HRC45 or above, providing excellent wear resistance. The gear shaft is crafted from high-strength alloy, which undergoes medium-frequency treatment for durability and precision. The crankshaft is made of 42CrMo alloy material, offering 1.3 times the strength of traditional 45 steel.

Additionally, the ball seat is constructed from Japanese-grade TM-3 sintered copper alloy, which results in a lower failure rate and increased operational lifespan. This combination of high-quality materials ensures that the machine operates smoothly, quietly, and efficiently over long periods, making it a valuable asset for any stamping operation.
