Product Introduction
Overview of Molds for Flexible Bending Centers
Molds for flexible bending centers are core process equipment in the bending of metal sheets. Compared with traditional bending machine molds, they feature higher versatility, rapid mold change capability, and process adaptability, and are mainly applied in flexible manufacturing scenarios involving multiple varieties and large batches of products. Their design must meet the automated operation requirements of bending centers while taking into account process parameters such as sheet material, thickness, and bending accuracy. They are key components for achieving efficient and precise bending processes.
I. Mold Structure Composition and Functional Features
1. Basic Structural Units
Upper Press Blade Assembly: Adopts a modular design, including segmented blade bodies (conventional segments and telescopic hinge blades) and a quick clamping mechanism. The blade material is mostly ultra-high-strength steel (e.g., 42CrMo). After heat treatment, the blade body hardness reaches HRC 48-52, and the cutting edge hardness is further increased to HRC 58-62 through laser treatment or nitriding, ensuring wear resistance and impact resistance. The clamping mechanism realizes quick connection with the bending center slider via eccentric locks or hydraulic/pneumatic clamping devices.
Lower Press Blade Assembly: Adopts an integral structure, including a mounting surface, mounting holes, and a cutting edge surface (the pressing surface matching the upper press blade). After heat treatment, its hardness reaches HRC 55-60, which also ensures wear resistance and impact resistance.
Upper and Lower Bending Blade Assemblies: Adopt an integral structure, including a mounting surface, mounting holes, and a ball-head bending part, enabling automated upper and lower bending.
Upper and Lower Auxiliary Blade Assemblies: Assist the upper and lower bending blades in the bending process.
Auxiliary Function Modules: Some molds are equipped with magnetic stripping devices, laser tool setting sensor interfaces, and stress monitoring chips, which can feed back the mold status in the bending process in real time to prevent sheet indentation or mold damage caused by overload.
2. Core Technical Features
Flexible Design: The upper press blade supports multi-segment splicing and combination (length can be steplessly adjusted from 50mm to 3000mm). The upper and lower bending blades realize automatic bending through programs, meeting the multi-process bending requirements of complex workpieces and reducing mold inventory by more than 50%.
High-Precision Adaptation: The overall mold precision reaches ≤0.02mm, and the working surface roughness is ≤Ra 0.8μm, avoiding scratches on the sheet surface.
Balance between Lightweight and High Strength: Finite element analysis is used to optimize the blade structure. Key stress-bearing parts (such as blade tips and ball heads) are treated to improve hardness or rounded, while non-stress-bearing areas adopt a hollow design. The overall weight is 15%-20% lower than that of traditional molds, reducing the driving load of the bending center.
3. Typical Application Fields
The main target markets and customer groups of the equipment are enterprises that need efficient and flexible production of sheet metal parts, such as:
-Chassis and Cabinet Industry: Network server cabinets, power distribution cabinets, etc.
-Elevator Industry: Elevator cabins and door panels.
-Kitchenware and Home Appliance Industry: Stainless steel kitchen cabinets, range hoods, etc.
-Special Vehicle Industry: Vehicle shells and internal structural parts.
-Other Sheet Metal Processing Plants: Processing enterprises undertaking orders of multiple varieties and small batches.
4. Main Product Features and Technical Advantages
True Full Automation
-Automatic Loading and Unloading: Usually equipped with a 6-axis robot to realize automatic grabbing and positioning of sheets.
-Automatic Mold Change: Equipped with a large-scale vertical tool magazine. During the processing, the upper mold (bending blade) can be automatically changed according to the program without manual intervention.
-Intelligent Lower Mold Avoidance: The segmented lower mold can automatically rise and fall according to the bending sequence, perfectly avoiding the already bent edges and realizing interference-free bending of complex sheet metal parts.
Intelligence and Usability
-Offline Programming Software: Usually equipped with a self-developed or integrated offline programming system. Users only need to import 3D models (e.g., STEP files), and the software can automatically generate bending plans, optimize the bending sequence, and calculate the configuration of bending blades and lower molds, greatly reducing the programming threshold and dependence on skilled technicians.
-"One-Click" Operation: From programming to processing, the automation level is high, aiming to realize foolproof operation.
High Precision and Efficiency
-High Rigidity Machine Body, Precision Servo Motor, and Grating Ruler Closed-Loop Control: These ensure the repeated positioning accuracy of bending angles and dimensions.
-Significant Efficiency Improvement: The time for traditional mold change, alignment, and test bending is reduced from several minutes/tens of minutes to seconds. The efficiency is significantly improved during continuous production.
Powerful Mold System
-Complete and Modular Upper Mold (Bending Blade) and Lower Mold System: It is highly compatible with their equipment, ensuring stability and precision.
