Core Performance Characteristics of Stretch Hydraulic Presses

Today, Jianlong Hydraulic Technology will share the core performance characteristics of general-purpose stretch hydraulic presses for your reference!

1. Precise Speed and Pressure Control 

Stretch forming requires precise control of speed and pressure. Modern stretch hydraulic presses generally possess the following characteristics:

1.1 Three-Stage Speed Adjustment: The slide can achieve three-stage speed control: "rapid descent—slow working feed—rapid return." Idle speed can reach 100-150mm/s, ensuring production efficiency; working speed can be controlled at 5-15mm/s, ensuring uniform metal flow and preventing tearing.

1.2 Adjustable Pressure and Stroke: Pressure, stroke, and holding time can all be flexibly adjusted according to process requirements to meet the stretching requirements of different materials and product depths.

1.3 Constant Pressure/Constant Stroke Dual Mode: Supports two control modes: constant pressure pressing (stopping when pressure reaches the set value) and constant stroke pressing (stopping when the slide reaches the set position). Repeat positioning accuracy can reach ≤±0.1mm.

2. High-Efficiency Hydraulic System Design

2.1 Master-Slave Cylinder Hydraulic Circuit: Utilizing an advanced master-slave cylinder design, it features high speed, low energy consumption, and low noise, reducing power consumption during standby.

2.2 Cartridge Valve Integrated System: Employing two-way cartridge valves, the hydraulic system experiences fewer malfunctions, minimizes reversing impact, and ensures high reliability.

2.3 Oil Temperature Control: Optimized hydraulic circuit design prevents oil temperature from rising excessively, ensuring stability during long-term continuous operation.

3. Servo Energy-Saving Technology

3.1 Servo Motor + Pump Drive: Optional servo control system, which can save over 40% energy compared to traditional hydraulic presses and reduce noise by 10-30 decibels.

3.2 On-Demand Oil Supply: The servo system adjusts motor speed and pump output according to actual needs, avoiding energy waste.
