1mm Electric Metal Wire Repeated Bending Test Machine

Main Technical Specifications

Standard Configuration

Advantages

The test machine is mainly composed of two main parts of the host mechanical system and electrical measurement and control system. The two-stage reducer drive is used to apply the test torque to bend the specimen repeatedly, and the number of bending tests is detected by photoelectric switch. After the sample is broken, it automatically shut down, pendulum reset, digital display automatically display, automatically record the number of bending specimens.

KASON BT-1 Steel Wire Reverse Bend Testing Machine - Target Applications

1. Core Application Area (Strictly Defined by Specimen & Test Type):
* Quality Testing of Fine Steel Wires & Strands:
* Target Specimens: Steel wires (or similar metallic wires) with diameters ranging from 0.3 mm to 1.0 mm.
* Test Type: Reverse Bend Testing (Repeated bending through ±90°). Evaluates the wire's:
* Ductility and Flexibility: Ability to withstand repeated bending deformation without failure.
* Surface Quality & Fatigue Resistance: Resistance to cracking or breaking under cyclic bending stress, revealing surface defects and material fatigue limits.
* Adherence to Bending Life Standards: Measures the number of reverse bends until fracture.

2. Primary User Industries & Functions (Aligned with Specimen Size & Automation):
* Wire Drawing & Fine Wire Manufacturing:
* In-process & Final QC: Essential for production lines manufacturing ultra-fine to fine steel wires (e.g., tire bead wire, spring wire, surgical suture wire, fine cables, mesh wire, EDM wire) to ensure product ductility and resistance to fatigue failure during handling, coiling, or service.
* New Wire Grade/Process Development: Testing new alloys, coatings, or drawing processes for their impact on bend fatigue life.
* Spring Manufacturing (Especially Small Springs):
* Wire Incoming Inspection: Verifying the bend fatigue resistance of fine wire used for small springs (e.g., electronics, instruments, medical devices, watch springs) critical for their functional lifespan.
* Spring Performance Correlation: Data informs spring design and expected durability under cyclic loading.
* Medical Device Component Suppliers:
* Testing Fine Wire Components: Evaluating the bend fatigue life of wires used in guidewires, orthodontic archwires, surgical staples, or other implantable/medical devices where repeated flexing occurs.
* Electrical & Electronic Component Manufacturers:
* Testing Lead Wires & Connector Pins: Assessing the ability of fine wires used in connectors, relays, or internal wiring to withstand repeated bending during assembly, servicing, or operation.
* Quality Control Laboratories & Research Institutions:
* Material Research: Studying the fatigue behavior and failure mechanisms of fine metallic wires under reverse bending loads.
* Standards Compliance Testing: Performing bend tests according to relevant industry or international standards (e.g., ISO 7801, ASTM E290, or specific customer/internal specs).
* Supplier Qualification: Testing wire from potential suppliers.

3. Key Features Enabling Precision in Target Scenarios:
* Ultra-Fine Wire Focus: Specifically designed for the 0.3mm - 1.0mm diameter range, filling a critical niche for testing very thin wires where bend fatigue is a major failure mode.
* Automated Testing & Data Recording:
* Automatic Shutdown & Count Retention: Stops automatically upon specimen breakage and holds/preserves the bend count.
* Touch Screen Display & Automatic Counting: Provides clear readout and eliminates manual counting errors (detected by photoelectric switch).
* Controlled Reverse Bending: Precisely applies repeated ±90° bends at a set frequency (<60 rpm) to simulate service conditions reliably.
* High-Cycle Capability: Capacity for up to 99,999 bends accommodates testing high-ductility wires.
* Simple Operation & Data Output: Touch screen interface and automatic functions enable efficient testing with minimal training. (Video tutorial aids setup/operation).
* Robust Construction (~200kg): Suitable for industrial lab environments.
