Professional testing instrument offering both manual and automatic working modes for flexible material impact testing of non-metallic materials.
Application
The Drop-hammer testing machine is specifically engineered for impact performance testing of non-metallic material products. This professional testing instrument evaluates impact resistance of non-metallic materials, providing reliable basis for assessing and verifying material quality. Both standard test method and gradient test method are applicable, enabling flexible adaptation to diverse testing requirements.
Key Features
Dual manual and automatic operation modes for convenient, simple operation
Single-chip microcomputer control system with automatic hammer clamping, lifting, height calibration and real-time display
Automatic zero-line calibration for test samples ensuring accurate positioning
Secondary impact prevention device avoids interference from redundant impacts
Integrated automatic protection and real-time prompt functions enhance safety
Electric adjustment capability in lower space improves positioning accuracy and reduces operator labor
Structure & Working Principle
The testing machine consists of workbench, anti-secondary impact mechanism, support tube, guide tube, hammer body, V-shaped anvil, automatic drop hammer mechanism, reducer, electric control cabinet and main frame.
Working principle: A hammer clamping assembly inside the guide tube lifts the hammer body automatically to preset height via motor and reducer. The release switch actuates to allow free fall along the guide tube, impacting the test specimen. Impact energy is calculated based on hammer mass and drop height.
After specimen impact, the anti-secondary impact mechanism controlled by photoelectric signal quickly locks rebounding hammer body to prevent repeated impact.
V-shaped anvil fitting below workbench features lead screws on both sides, with handwheel-driven lifting and lowering mechanism.
