Mold

The alliance mold (fully quenched) uses 42CrMo (42 chromium-molybdenum) as the high-quality mold material. It undergoes comprehensive heat treatment processes (full quenching, laser quenching, nitriding treatment) to ensure the mold's load-bearing capacity and service life. High-end precision machine tools are used to ensure the mold's high precision.

Mechanical Deflection Compensation Workbench

To ensure the good machining accuracy of the workpiece, the Alliance LRMR mechanical lower workbench compensation mechanism is adopted. The multi-point mechanical deflection compensation device can form an ideal position convex curve. When machining parts of different thicknesses or lengths, the CNC system can automatically control the precise protrusion of the device, thus ensuring good accuracy during the machining process. This compensation device not only has CNC lateral automatic compensation functions but also manual longitudinal compensation.

Motor

The main servo motor adopts the first-tier brand Inovance servo motor.

High Precision: The Inovance servo motor is equipped with an encoder in its electronic control system, which can accurately obtain position signals and control positioning errors to a minimal level, ensuring high-precision motion control.
Quick Response: The Inovance servo motor has a very fast response speed, capable of responding to control signals within microseconds, achieving rapid and accurate dynamic control.
Strong Control Performance: The controller of the Inovance servo motor can control various parameters of the motor, including speed, position, and acceleration. It can also monitor changes in various parameters in real-time to meet different control requirements.
Good Stability: The Inovance servo motor has an automatic adjustment function that can automatically recognize load changes and make timely adjustments.

German Rexroth Hydraulic System

The German REXROTH company's specialized hydraulic system for bending machines (electro-hydraulic proportional servo synchronous control system) is used. This system is a closed-loop position control system that dynamically detects the synchronous error of the slider through a grating ruler. The electro-hydraulic servo valve of the CNC system corrects the synchronous error of the slider, ensuring that the slider remains parallel to the workbench even under complete eccentric loading. The slider synchronization accuracy is ≤ ±0.02mm.

Mechanical Design

Finite element analysis (FEA) of the entire machine is performed. Professional analysts use Ansys software to conduct FEA on each device's frame, slider, workbench, and upright plates, ensuring the strength and rigidity of the entire machine and guaranteeing its service life.

Heat Treatment

The frame adopts an all-steel welded structure. Stress relief for the machine body and critical welding points is achieved through normalizing and high-frequency vibration. This ensures the overall precision of the machine, excellent rigidity, and superior resistance to torsion and tilt. These measures guarantee the long-term stability of the machine during prolonged use.

Frame Welding

The welds are free from defects such as undercuts, porosity, and cracks. The external surface welds are ground smooth with no splatter. The overall equipment surface is flat, smooth, and free from bumps or depressions.

Integral Machining

The frame and slider are machined in one go using large-scale CNC floor-type boring and milling machines, ensuring the perpendicularity and parallelism of all mounting surfaces. Detailed work instructions and experienced technicians guarantee precise alignment at every stage. The production is divided into functional areas and carried out in a streamlined process.
