1. High-Rigidity Machine Frame: Robust Architecture for Long-Term Dimensional Stability

The machine body is the core load-bearing structure of a pneumatic press; its rigidity and stability directly determine stamping precision and equipment lifespan. Zhenghao Youbang Heavy Industry adoptsAll-steel fully welded body technology, formed from a single piece of high-strength premium steelDual stress-relief process: High-temperature tempering + high-frequency vibrationEliminates internal welding stresses to ensure the frame remains deformation-free and dimensionally stable under prolonged high-load stamping conditions, guaranteeing consistent stamping accuracy from the source.

• Reinforced structural designThe machine body features a fully enclosed box-frame design with reinforced wall and work panels. Integrated stiffeners optimize load paths, improving impact and torsional resistance by 35% as validated through ANSYS finite element analysis. It withstands stamping loads from 16T to 160T, meeting the demands of high-strength sheet metal forming.

• Precision Machining ProcessThe machine base rail surfaces and worktable mounting surfaces are machined in a single setup on a CNC gantry milling machine, with flatness and parallelism controlled to ≤0.02mm. This ensures smooth slider movement, uniform load distribution, and consistent precision across mass-produced stamped parts.

• Unified WorkbenchThe worktable and machine body are precisely fitted. Constructed from high-strength steel plate with precision grinding, the surface roughness is Ra ≤ 1.6 μm. Equipped with standard T-slots for quick mold installation and positioning, it supports various mold specifications.

II. Pneumatic Clutch and Brake Technology: Dry Composite for Efficient, Smooth Power Control

The pneumatic clutch-brake is the core power control unit of a pneumatic press, directly impacting equipment efficiency, smoothness of start/stop operations, and safety. Independently developed by Zhenghao Youbang Heavy Industry.Dry-type Pneumatic Clutch and Brake TechnologyEquipped with high-wear-resistance friction pads and a precision sealing structure, combined with intelligent pneumatic control logic to achieveQuick engagement, smooth braking, low energy consumption, long service lifepower control effect.

• Core Structure DesignThe clutch-brake assembly is integrated within the flywheel, featuring a sealed unit with built-in high-precision bearings to reduce transmission resistance. Friction plates are made from imported, high-wear-resistant materials with high hardness and stable friction coefficients, extending service life to over 8 years and reducing maintenance costs by 40%.

• Pneumatic Control PrinciplesPrecisely controls compressed air flow via a solenoid valve. Pressing the foot switch directs air into the clutch cylinder, pushing the piston to engage and transmit flywheel power to the crankshaft. Releasing the switch vents the cylinder, allowing a spring to quickly reset the brake and stop the slider immediately. Start/stop response time is ≤ 0.1 seconds, eliminating double-stroke risks.

• Safety Interlock ProtectionThe clutch-brake assembly includes an overload protection device that automatically cuts power when stamping force exceeds the rated limit, safeguarding both equipment and dies. Its dual-seal design prevents dust ingress, ensuring reliable operation in harsh production environments.

3. Precision Transmission Technology: Crankshaft and Connecting Rod for Stable, High-Efficiency Power Delivery

The transmission system converts power into the slider's reciprocating motion; its precision and stability directly impact stamping accuracy and production efficiency. Zhenghao Youbang Heavy Industry adoptsHigh-precision crankshaft connecting rod transmission technologyCore components are precision-machined and heat-treated, with optimized transmission clearance to achieveLow noise, low vibration, high precisionpower transmission.

• High-strength crankshaftForged from premium alloy steel and treated with quenching + surface hardening, achieving a hardness of HRC52-58 for high bending strength and excellent wear resistance. The crankshaft journals are precision-ground to maintain roundness and cylindricity within ≤0.01mm, ensuring smooth operation with minimal clearance when paired with high-precision bearings.

• Precision Linkage Mechanism: The connecting rod is cast from steel and stress-relieved to minimize deformation. Its spherical head features an adjustable design paired with a precision screw, enabling accurate adjustment of the slider stroke with a tolerance of ±0.01mm to accommodate various stamping depths.

• Low-vibration operationThe transmission system is dynamically balanced and paired with machine body vibration-damping pads, ensuring operating noise ≤ 75 dB and vibration amplitude ≤ 0.03mm. This improves the production environment and extends the service life of both equipment and molds.

4. Intelligent Pneumatic and CNC Technology: Pneumatic Control + Digital Display for Convenient, Efficient, and Easy Operation
