Main Structure
Automatic Adjustable v opening dies
10 seconds to adjust the opening degree from 0 to 100 mm.
- High-quality mold steel, overall heat treatment process, and tempering to eliminate internal stress
- Key parts adopt laser quenching, which ensures the high strength and long service life of the mold.
- It can be installed on bending machines of all brands, and the mold control system is compatible with the bending machine controller system
- High-quality branded servo motors, high-precision reducers, and precision ball screws are adopted to ensure the fast and accurate adjustment of the mold opening size.
- Dust-proof cloth is provided to protect the mold from dust and debris, thus preventing any impact on the mold's normal operation.
Upper Die Base / Lower Die Base
Basic Support Module: Serves as the load-bearing and installation foundation
- It is made of high-strength alloy steel (e.g., 42CrMo), featuring extremely high rigidity and deformation resistance.
- The upper die base is used to fix the cutting edge of the upper die.
- The lower die base integrates an opening adjustment mechanism.
Die Core / Cutting Edge
Opening Adjustment Drive Module: Enables changes in opening size
- The working components that come into direct contact with the plate are made of high-hardness tool steel (e.g., Cr12MoV) through heat treatment, ensuring wear resistance and bending accuracy
- The lower die core is designed as a detachable or slidable structure to match the opening adjustment.
Drive Unit:Servo Motor + Ball Screw
Opening Adjustment Drive Module: Enables changes in opening size
- The servo motor provides precise rotational speed and torque control
- while the ball screw converts rotational motion into linear motion
- enabling high precision (typically up to 0.01 mm) for opening adjustment.
- Hydraulic drive is also used for large-scale molds to provide greater thrust.
Adjustment Component
Opening Adjustment Drive Module: Enables changes in opening size
- Movable Die Insert, Synchronous Gear / Rack
- The movable die insert is mounted on the lower die base and driven by a lead screw or rack, moving synchronously left and right along the guide rail to change the opening size of the lower die.
- The synchronous gears/racks ensure that the inserts on both sides move at a consistent speed, preventing opening deviation.
Guide Rail
Guiding and Positioning Module: Ensures adjustment accuracy and bending stability.
- Usually linear guides or precision pin-bushing structures, mounted between lower die base and movable inserts to ensure horizontal movement only, no vertical/front-back play.
Positioning Detection Unit
Guiding and Positioning Module: Ensures adjustment accuracy and bending stability.
- It integrates a linear scale or encoder to detect the position of the movable insert in real time, and feeds the data back to the control system to form a closed-loop control, preventing the accumulation of adjustment errors.
Locking Mechanism
Guiding and Positioning Module: Ensures adjustment accuracy and bending stability.
- After adjustment to the correct position, the movable insert is locked via an electromagnetic lock or hydraulic clamping device to prevent changes in the opening size caused by force application during the bending process.
Control Unit
Automated Control Module: Enables "fully automated" operation
- It is built with a PLC or a dedicated controller, which receives instructions from the bending machine host (such as parameters of sheet thickness and bending angle), automatically calculates the required opening size, and sends driving signals to the servo motor.
Human-Machine Interface (HMI)
Guiding and Positioning Module: Ensures adjustment accuracy and bending stability.
- Through the operation panel of the bending machine, you can manually input the opening size parameters or call the preset process parameter library. Meanwhile, information such as the current opening size and adjustment progress is displayed in real time.
