The Modular Automatic Feeding System for Presses is a key infrastructure for achieving "unmanned
processing" and "flexible manufacturing" in smart factories by 2026. Against the backdrop of the stam
ping industry's transformation from traditional mechanical drives to high-precision automation, linear
modules (such as ball screw modules, synchronous belt modules, and linear motor modules) have
become the core link connecting decoiling equipment, leveling machines, and presses.
The following is a detailed technical introduction and industry analysis of the application of modules in
automatic feeding systems for presses.
I. System Composition and Technical Principles
Automatic feeding modules for presses typically adopt a Cartesian coordinate system structure, using
single-axis or multi-axis combinations to accurately feed sheet metal or strip material into the stamping
die.
Power and Transmission Core:
Servo Drive: The mainstream solutions in 2026 all use high-inertia AC servo motors (such as the Inovance
SV680 series), achieving micron-level position closed-loop control through high-resolution encoders.
Transmission Form: For high-precision requirements, precision ball screw modules are used; for long
-stroke, high-speed (above 3 m/s) requirements, synchronous belt modules or linear motor modules are
preferred.
Clamping and Actuating Mechanism:
The front end of the module is equipped with pneumatic grippers, vacuum suction cups, or electromag
netic suction cups. The actuating mechanism can be quickly replaced for different materials (aluminum
alloy, high-strength steel, silicon steel sheets), enabling flexible gripping.
Control System (Brain):
A motion control card or PLC (such as the Inovance AM series) is used to achieve "cam synchronization"
between the feeding module and the press slide movement through bus communication (EtherCAT).
II. Core Advantages of Modular Feeding
1. Extremely High Stepping Accuracy
Traditional mechanical roller feeding is prone to slippage due to material thickness and surface oil conta
mination. Servo module feeding, however, uses programmed step settings, achieving positioning accura
cy of approximately ±0.02mm. This is crucial for the high-density, multi-station progressive dies that will
be popular in 2026, effectively preventing die collision accidents caused by feeding deviations.
2. Excellent Flexibility and Adjustment
In a "small batch, multi-variety" production model, the modular feeding system offers significant advanta
ges. Operators only need to input the material length, feeding cycles, and speed curve on the HMI touch
screen to complete a product changeover, eliminating the need for manual adjustment of mechanical
eccentric wheels as required by traditional feeding machines.
3. Deep Integration with Punch Presses
By 2026, the technology will enable electronic cam (E-Cam) synchronization between the module and
the punch press. The module can automatically find the optimal feeding window (i.e., the moment the
mold opens) based on the rotation angle of the punch press crankshaft, minimizing cycle time and incre
asing strokes per minute (SPM).
4. Secondary Development and Scalability
The modular design means the system can be customized according to the factory layout. For example,
it can be configured as a "three-axis linkage system," not only responsible for feeding but also handling
scrap removal and finished product stacking, achieving "multi-functional operation."
III. Typical Application Scenarios
New Energy Vehicle Structural Components: When processing automotive longitudinal beams and batte
ry casings, the modular feeding system is responsible for feeding high-strength steel plates into large-
scale progressive die presses. Its high-rigidity structure can withstand the enormous vibrations generated
during stamping.
Motor Stator and Rotor Cores (Silicon Steel Sheets): On high-speed punch presses, the modular feeding
system, in conjunction with Inovance high-speed drives, achieves precise feeding hundreds of times per
minute, ensuring the alignment of the notches in the silicon steel sheet laminations.
Precision Electronic Lead Frames: Utilizing ultra-small linear motor modules, it provides extremely high
acceleration in thin-plate stamping, meeting the precision processing requirements of 5G/6G communic
ation components.
IV. Technological Evolution Trends in 2026
AI Vision Error Prevention and Compensation:
The latest modular feeding system integrates 3D vision sensors. When deformation or deviation from
the centerline of the material strip is detected, the module will automatically adjust the X-Y axis coordina
tes in real time for compensation, eliminating the need for manual adjustment and downtime.
Digital Twin Monitoring:
Through a digital twin platform, companies can remotely monitor the screw wear status and motor torq
ue fluctuations of each feeding module. Before a failure occurs, the system will provide early warnings
based on big data, enabling a shift from "emergency repair" to "preventive maintenance."
Carbon Neutrality and Energy Recovery:
By 2026, servo control technology will widely adopt energy feedback mechanisms. The electrical energy
generated during the rapid deceleration of the module can be fed back to the power grid or common
DC bus, for use by the press, significantly reducing overall energy consumption.
V. Conclusion
The modular automatic feeding system for stamping presses is no longer merely an auxiliary device, but
a core component in the digital transformation of stamping workshops. Through high-precision linear
motion control, it solves the contradiction between efficiency, precision, and flexibility. With further
breakthroughs in the performance of domestically produced servo motors and high-precision transmiss
ion components by 2026, the modular automatic feeding system is helping the Chinese stamping indus
try steadily move towards the top of the global industrial chain.
