The Steel Hook Bending Tester Machine is designed to evaluate the bending resistance of steel hooks used in footwear reinforcement. The instrument applies a controlled 180° rotation to the hook around a standardized column, allowing objective assessment of bending performance and structural integrity. The tester is suitable for quality control in footwear manufacturing and materials testing laboratories.

Applications

(1)Testing steel shanks or hooks used in men’s shoes, women’s shoes, and children’s shoes for longitudinal and lateral bending resistance.

(2)Evaluation of reinforcement materials in safety footwear, including steel-toe and composite-toe shoes.

(3)Inspection of footwear prototypes to verify shank or hook performance before mass production.

(4)Quality control for athletic, casual, and formal shoes to ensure compliance with design and regulatory standards.

(5)Laboratory assessment of metal inserts or stiffeners used in shoe soles and heels.

Technical Parameters

Product Features

(1)Motor-driven mechanism ensures controlled and consistent bending of steel hooks.

(2)Rotates hooks 180° around a standard column (φ10 mm) for repeatable testing.

(3)Objective quality assessment through visual inspection for cracks or fractures.

(4)Compact and robust construction suitable for laboratory and production environments.

(5)Simple operation with minimal setup, suitable for routine quality control.

Test Procedures

(1)Secure the steel hook in the provided fixture.

(2)Align the hook with the center column (φ10 mm).

(3)Activate the motor to rotate the hook 180° around the column.

(4)After rotation, inspect the hook surface for cracks, fractures, or other deformation.

(5)Record results and compare against standard requirements.

Maintenance Information

(1)Keep the machine clean and free of metal debris.

(2)Inspect moving parts periodically for wear and lubrication needs.

(3)Verify motor operation and alignment of the bending column.

(4)Store in a dry environment to prevent corrosion.

(5)Check electrical connections regularly to ensure safe operation.
