630T Four Column Hydraulic Press for Deep Drawing Rotovator Chain Cover

Complete Technical Data

Capacity

• Nominal Force: 630 Tons (6300 kN) of downward ram pressure to form medium-to-thick structural steel plates.
• Blank Holder Cushion Force: 250 Tons of adjustable bottom cushion pressure to securely control material flow and eliminate wrinkling during deep channel drawing.

Structural Design

• High-Rigidity Four-Pillar Layout: Employs four solid, precision-ground columns that distribute structural loads evenly and maintain tight alignment tolerances.
• Heavy Slider Guidance System: Long guide bushings slide smoothly along the pillars, counteracting severe off-center forces caused by asymmetrical die profiles.

Frame Type

• Four-Column Open Architecture: Provides a highly flexible 360-degree operational envelope, enabling unrestricted loading for heavy steel blanks and automated parts handling.
• Stress-Relieved Welded Construction: The top crown, moving slide, and bottom bed are fabricated from thick-plate steel, thermal-stress relieved to guarantee geometric stability.

Hydraulic System

• High-Performance Cartridge Block System: Features a top-mounted hydraulic power pack with low-noise axial piston pumps for responsive, leak-free pressure management.
• Dual-Pump Flow Regulation: Utilizes split-flow pump configurations to independently power the main drawing ram and the blank-holding cushion circuits.

Main Ram Stroke

• Maximum Travel: Standard stroke length up to 700mm–900mm, offering ample depth for stepping profiles and long vertical agricultural housings.
• Digital Position Feedback: Uses linear transducers to track ram displacement continuously, maintaining tight control over bottom-dead-center positioning.

Working Hydraulic Pressure

• Max Operating Pressure: Rated at 25 MPa (250 bar) for dependable, continuous execution of high-tonnage stamping operations.
• Step-less Pressure Adjustment: Digital pressure valves communicate with the PLC to scale hydraulic force dynamically during different stroke phases.

Daylight Gap

• Maximum Open Height: Generous vertical clearance (typically 1100mm–1400mm) allowing for deep punch tools, extraction heights, and thick lower cushion pin plates.
• Shut Height Limits: Tailored to easily fit deep-profile multi-stage drawing, sizing, and piercing die blocks.

Approach Speed

• Fast Downward Velocity: High-speed approach (up to 140–180 mm/s) to sweep through the open daylight gap quickly, optimizing total cycle times.
• Soft-Touch Slowdown: Automated valve throttling smoothly decreases velocity right before blank contact, preventing tool impact damage.

Pressing / Drawing Speed

• Regulated Deep Draw Velocity: Slow, constant pressing speed (typically 4–10 mm/s) engineered to match the plastic deformation thresholds of structural steel.
• Coordinated Cushion Displacement: The lower cushion yields precisely under punch force, maintaining constant resistance to control wall thickness uniformity.

Return Speed

• Rapid Retract Velocity: Fast upward stroke (up to 110–140 mm/s) to quickly extract the drawing punch and clear the working area for the next cycle.
• Hydraulic Decompression Logic: Standard slow initial decompression cycle prevents hydraulic shocks and extends pipe and weld lifetimes.

Bed / Platen Size

• Bolster Plate Dimensions: Large working table area (e.g., 1500mm x 1300 mm) sized to match long, narrow tractor rotovator chain cover dies.
• Standard T-Slot Arrangement: Machined with precise T-slots and custom cushion pin layouts for rapid and highly secure die clamping.

Columns

• Hardened Alloy Steel Pillars: Fabricated from high-tensile 45# forged steel, induction-hardened, and finished with thick hard chrome plating.
• Precision Wear Seals: Heavy-duty dust and oil seals on guide bushes preserve structural tolerances and prevent environmental contamination from factory grit.

Working Envelope

• Pillar Clearance Windows: Maximized space between the columns supports front-to-back manual part feeding or side-to-side inline conveyor layouts.
• Ergonomic Bed Height: Bolster face height optimized for high-capacity industrial lifting, positioning, and comfortable die maintenance access.

Control System

• Central Microprocessor PLC: Managed by an industrial-grade PLC (e.g., Siemens or Mitsubishi) for robust, interference-free sequential processing logic.
• Touch-Screen Operator Interface: Color HMI screen displaying live tonnage monitoring, real-time error logs, cycle counters, and electronic recipe configuration.

Main Motor Power

• Heavy-Duty Electric Drive: Powered by a high-efficiency induction motor (typically 37kW–55kW) built to handle severe continuous operating loops.
• Energy Management Modes: Standard intelligent shutdown/idle loops decrease motor load when the press is waiting for material loading.

Valves & Hydraulics

• Logic Integrated Manifolds: Multi-valve blocks minimize piping layout complexity, cutting the danger of pressure drops and fluid leakage.
• Premium Global Vendor Standard: Equipped with premium valves (Rexroth, Yuken, or equivalent) ensuring international parts swapping capability.

Automation

• Feeder & Robot Connectivity: Pre-wired electronic I/O terminals and digital bus protocols support ready integration with automatic sheet destackers.
• Automated Lubrication System: Central motorized pump automatically supplies metered lubricants to columns and high-wear sliding points.

Safety Features

• Safety Light Curtains: Category 4 optical safety guards across loading faces instantly kill hydraulic flow if the light grid is broken.
• Two-Hand Control Console: Requires simultaneous dual palm-button engagement from the operator to cycle the press, keeping hands clear of moving parts.
• Anti-Fall Locking Assembly: Equipped with dual hydraulic safety valves and a mechanical slide catch bar to securely lock the ram during die setup.
