H1: J39 Series Closed Straight Side Press – Intelligent Solution for High-Precision Stamping
In automotive manufacturing, new energy equipment, and high-end component processing, closed straight side presses are core equipment for multi-station forming of complex workpieces due to their superior stability and precision. The J39 series integrates finite element optimization, high-strength welded frames, and intelligent transmission technology to deliver one-stop solutions for deep drawing, precision punching, and bending, empowering customers to achieve efficient production and quality enhancement.
H2: High-Strength Frame Design – The Foundation of Precision Stamping
H3: FEA Optimization + Welded Preloading – Industry-Leading Rigidity
Key components (beams, columns, base) of the J39 series undergo full-process finite element analysis (FEA), optimizing material stress distribution by 40%. Combined with welded structure tension bolt preloading, the overall rigidity reaches 1/8000+, with strength 30% higher than traditional cast frames. This design effectively suppresses stamping vibration (amplitude ≤0.05mm), providing stable support for progressive dies and eliminating workpiece dimensional deviations caused by frame deformation. As a premium straight side press, it ensures reliability in high-tolerance applications.
H3: Octagonal Right-Angle Guide Rails – Micron-Level Precision Control
The slider features an octagonal right-angle guide rail structure, with a contact area 50% larger than traditional four-sided guides. Combined with hydraulic preloading, guide rail clearance is controlled within 0.01mm. Test data shows the J39 series achieves a bottom dead center repeat positioning accuracy of ±0.01mm and slider straightness ≤0.02mm/m, making it an ideal straight side press for high-precision forming of automotive body panels and new energy battery cases.
H2: Innovative Transmission System – Breaking Through Process Bottlenecks
H3: Opposite Direction Transmission + High-Strength Gears – Low Load, High Smoothness
Using opposite direction transmission, lateral forces during gear meshing are canceled out, reducing slider lateral force by 60% compared to same-direction systems. Paired with high-speed herringbone gears (ISO 6 precision) and low-speed ground hard-tooth-surface spur gears, this straight side press achieves 98% transmission efficiency and noise ≤85dB. Even at 80 strokes/min, it maintains uniform pressure output, with material utilization exceeding 97%.
H3: Split Pneumatic Clutch & Brake – Fast and Reliable Response
Standard with a split pneumatic friction clutch/brake (optional imported wet type, response time ≤50ms), the J39 series ensures clutch-brake synchronization error <0.5°, critical for precise multi-station feeding and stamping coordination. For continuous drawing of new energy battery cases, this straight side press enables 0.1-second-level start/stop control to avoid workpiece cracking from action lag.
H2: Intelligent Control and Safety Protection – Efficient Production Assurance
H3: Dual-Loop Cam Control – Flexibility Meets Stability
Equipped with an electronic cam + mechanical cam dual-loop control system, this straight side press supports real-time programming of process parameters (e.g., station-specific pressure/speed adjustment) for flexible production of complex workpieces. The mechanical cam provides hardware redundancy, reducing system failure rates by 40% under extreme conditions.
H3: Full-Process Safety and Intelligent Lubrication
High-Sensitivity Overload Protection: Triggers shutdown and alarm within 0.1 seconds of overload, locking mold position to protect core components;
Automatic Heavy-Duty Oil Lubrication: Timed lubrication for 15 key components (gearboxes, guides, etc.), with optional temperature control (±2℃), extending maintenance cycles to 6 months and reducing wear by 50%;
Imported Safety Dual Solenoid Valves: ISO 13849-1 compliant, with ≤30ms response time, ensuring reliable emergency braking in this straight side press.
H2: Modular Configuration – Adaptable to Diverse Scenarios
H3: Flexible Optional Features – Customized for Your Needs
Air Cushion: Dynamically adjusts blank holder force (0-500 tons) to prevent deep-drawing wrinkles, ideal for complex curves in automotive fuel tanks and battery cases;
Ton-Meter & Vibration-Damping Pads: Real-time pressure monitoring and 90%+ vibration isolation, suitable for precision electronic component workshops;
Industrial IoT Interface: Supports Profinet/EtherCAT, enabling real-time data uploads to MES for full production traceability.
