Core Technology Advantages: Exceptional Precision and Rigidity

Superior Structural Rigidity and Accuracy

• Achieves stringent JIS 1-grade accuracy standards for precision stamping and deep drawing.

• Features an integral welded steel frame construction with stress-relieving treatment, providing exceptional rigidity. The 1/10000 frame stiffness exceeds industry standards for deep drawing press machines, minimizing deformation and ensuring long-term operational stability.

Precision Guidance and Stable Transmission

• Incorporates an eight-sided high-precision long guide rail system for maximum slide stability and guiding accuracy, ensuring dimensional consistency during complex pressing drawing processes.

• Utilizes a high-rigidity eccentric shaft drive gear with an idler gear assembly. This double action deep drawing press machine design enhances transmission stability, increases connecting rod force span, and significantly improves resistance to eccentric loading - critical for deep drawing operations. The load-bearing component strength surpasses conventional crank presses, eliminating crankshaft deflection issues inherent to traditional designs.

Advanced Lubrication and Simplified Adjustment

• Employs an electric thin-oil circulation lubrication system for automatic, metered lubrication of critical friction points during intensive pressing drawing cycles, reducing wear and extending service life.

• Precision adjustment utilizes a single-sided method: left-side solid contact with right-side cylindrical pin locking, streamlining setup and enhancing accuracy retention.

Integrated Automation: Ensuring Efficiency and Stability

• Combines a three-in-one servo feeder, conveyor belt, and precision progressive die into a synchronized automation system for this aluminium case deep drawing press.

Frequently Asked Questions (FAQ)

Q1: What defines "JIS Grade 1 Accuracy" for this deep drawing press machine?
A1: JIS (Japanese Industrial Standard) Grade 1 represents the highest accuracy class for straight-side presses. It mandates stringent tolerances for slide parallelism, verticality, and table flatness, ensuring exceptional dimensional stability and part consistency during high-speed stamping and deep drawing operations, essential for precision battery covers.

Q2: How does 1/10000 frame stiffness benefit aluminium case deep drawing press operations?
A2: This high stiffness value indicates superior resistance to elastic deformation under load. Benefits include:

• Extended Die Life: Improved die alignment reduces uneven wear and galling during intensive pressing drawing.

• Enhanced Part Accuracy: Minimizes dimensional variation and improves cover flatness in deep drawing.

• Process Stability: Increased resistance to eccentric loading ensures reliability in multi-station stretching crucial for battery shell production.

Q3: Why is the HP2 configured as a double action deep drawing press machine?
A3: The double-action configuration (with independent blank holder and punch controls) provides precise control over material flow during deep drawing operations. This is essential for forming complex, high-precision aluminium battery covers without wrinkles or splits, especially with challenging materials and geometries.

Q4: What advantages do eight-sided guide rails offer for pressing drawing operations?
A4: Eight-sided guide rails provide greater contact area and constraint than typical designs. This delivers superior guiding accuracy and stability during deep drawing, critically minimizing slide tilt and vibration - essential for maintaining precise concentricity between punch and die throughout the drawing stroke.

Q5: What is the function of the three-in-one servo feeder in this aluminium case deep drawing press line?
A5: The three-in-one servo feeder integrates decoiling, leveling, and feeding functions. Its key roles are:

• Precision Feeding: Servo-driven control achieves high-accuracy material advancement (±0.03mm), critical for progressive deep drawing.

• Automated Efficiency: Enables continuous, synchronized material handling with the press for stable, high-volume production.

• Material Conditioning: Ensures flat, stress-free material enters the deep drawing press machine, preventing defects.

Q6: Why is the eccentric shaft drive with idler gear superior to a crankshaft for a double action deep drawing press machine?
A6: This design is fundamental to the HP2's performance in deep drawing:

• Eccentric Load Resistance: Increased connecting rod span significantly improves off-center load capacity, vital for multi-station drawing where forces are uneven.

• Minimized Deflection: The eccentric shaft assembly offers greater strength and reduced elastic deformation compared to crankshafts, maintaining precision alignment throughout the drawing stroke.

• Smoother Operation: The idler gear optimizes force transmission, resulting in quieter running and increased durability for demanding battery cover deep drawing cycles.
