Electric Hook Core Bending Resistance Tester: Key Specifications & Applications

The Electric Hook Core Bending Resistance Tester is designed to evaluate the flexibility and structural integrity of hook-shaped components under bending stress. This article details its compliance with industry standards, technical parameters, operating mechanism, and testing protocols.

Applicable Standards

The tester aligns with global benchmarks like ASTM F2083 (metallic hook testing), ISO 8821 (load-bearing fastener standards), and DIN 51221 (material fatigue testing). These standards define load limits, cycle requirements, and deformation thresholds for safety-critical components.

Main Parameters

Working Principle

The machine uses a servo-controlled hydraulic actuator to apply precise bending forces. A 3-point bending fixture clamps the hook core, while laser sensors monitor displacement in real time. The system integrates PLC control and data acquisition software to automate testing and generate compliance reports.

Test Principle

Sample Mounting: Secure the hook core in the fixture, aligning the bend axis with the specimen’s geometric center.

Force Application: Gradually increase the load to the target force/angle, simulating operational stress.

Failure Analysis: Track deformation, cracks, or breaks. Results are compared against standard thresholds to determine pass/fail.

This tester ensures components meet performance requirements in industries like construction, automotive, and aerospace, where hook integrity is critical for safety.
