JH21-25 Gap Frame Automatic Punching Press Machine
Product Description
The JH21-25 is a high-performance open-gap frame punching press machine engineered for precision stamping applications, delivering a rated force of 250kN. Designed for efficiency and safety, it is extensively utilized in the production of small metal components, including punching, blanking, bending, and shallow drawing operations.
Advantages:
One year warranty, free parts within warranty
International standards electric elements
Shipment assembly easy for installation
CE safety ceritificate for European markets, conform to NR12 standards for Brazil market.
More than two-decades manufacturing experience in this type of pneumatic presses
Key Features:
1. Automated Operation:
Equipped with three selectable working modes—Jog (for precise positioning), Single Cycle (for individual part processing), and Continuous Cycle (for high-volume production)—ensuring versatility across diverse manufacturing scenarios.
2. Advanced Control System:
Features a wet-type pneumatic clutch and brake mechanism, meticulously controlled by a dual-safety solenoid valve. This design guarantees rapid response times (≤0.3s) and enhanced operational reliability, minimizing downtime.
3. Safety Compliance:
Meets stringent industry standards (e.g., CE, GB/T 27678-2011) with integrated safety measures, including dual-hand control buttons, photoelectric safeguards, and overload protection systems, ensuring a secure working environment.
4. Precision Engineering:
Boasts a rigid gap-frame structure with high resistance to deflection, complemented by a pneumatic counterbalance system to reduce vibration and improve part accuracy.
