The servo-driven die press is an intelligent forging equipment that uses a servo motor as its power source
and a high-precision ball screw or electric cylinder to drive a slider for pressure forming. Its core lies in its
closed-loop control system, which provides real-time feedback and dynamic adjustment of pressure, displ
acement, and speed. This overcomes the rigid motion limitations of traditional mechanical or hydraulic
presses, enabling flexible programming of process parameters and full-process digital control.
Core Structure and Working Principle
The servo-driven die press consists of a servo motor, a reduction transmission mechanism, a high-precision
ball screw, position/pressure sensors, a programmable logic controller (PLC), and a human-machine interfa
ce. During operation, the servo motor receives control commands and, through precise control of the rotatio
n angle and torque, drives the screw to convert rotational motion into linear motion, driving the slider to
complete a five-stage process cycle: "rapid advance—detection—pressing—pressure holding—return." The
system incorporates pressure sensors and encoders to collect pressure-displacement curves in real time,
achieving micron-level precision control (repeatability up to ±0.01mm) and supporting online quality judg
ment and automatic rejection of defective products.
Key Technical Advantages:
High Precision: Pressure control accuracy ≤ ±1%FS, displacement repeatability up to 0.01mm, suitable for
precision assembly of tiny parts.
High Flexibility: Can store 100+ sets of press-fitting programs, allowing one-click switching between different
product processes, achieving "one machine for multiple uses".
Significant Energy Saving: Consumes power only during operation, with near-zero no-load energy consumpt
ion, saving 40%–80% energy compared to traditional hydraulic presses, resulting in annual electricity saving
s exceeding 50,000 RMB (based on a 200T machine).
Low Noise and Environmentally Friendly: Operating noise <65dB, no risk of hydraulic oil leakage, meeting
cleanroom standards.
Intelligent Interconnectivity: Supports industrial protocols such as Profinet and TCP/IP, can be integrated
into MES systems, enabling full lifecycle traceability of press-fitting data.
