Drop Hammer Test Equipment Offering Versatility in Testing Various Sample Sizes and Shapes Under Controlled Conditions
Product Description:
The Drop Hammer Impact Tester / Drop Weight Tear Tester is specifically engineered to conduct impact testing on plastic pipes, sheet metals, and their finished products. Its core purpose is to accurately evaluate and determine the impact resistance properties of these materials, providing reliable data support for material quality control and product performance validation.
The control system of the tester adopts advanced digital control technology, enabling precise parameter setting, automatic zero adjustment, and automated hammer lifting and dropping. Notably, it is equipped with a built-in anti-secondary impact mechanism, which effectively prevents unintended secondary impacts during the test process—ensuring the accuracy of test results and enhancing operational safety.
Product Structure and Working Principle:
Core Component Composition:
The tester consists primarily of a workbench, secondary impact prevention mechanism, support tube, guide tube, hammer body, V-block assembly, automatic drop hammer mechanism, reducer, electric control box, support bracket, and other key structural components.
Operating Principle:
A hammer holder is mounted inside the guide tube. Driven by a motor and reducer, the holder hoists the hammer body to the preset test height. Activating the drop trigger switch releases the hammer body to fall freely within the guide tube and strike the test specimen, thereby fulfilling the impact test objectives.
Impact Energy Calculation & Secondary Impact Prevention:
The impact energy is precisely calculable based on the hammer body’s weight and preset drop height. Upon striking the test specimen, the device prevents the hammer body from rebounding and causing secondary impact. Equipped with photoelectric sensing control technology, the system detects the rebounding hammer body in real time and triggers the secondary impact prevention mechanism to rapidly clamp the hammer. This design effectively eliminates the risk of secondary impact, ensuring the accuracy and reliability of test results.
V-block Assembly Adjustment Mechanism:
The V-block assembly is mounted beneath the workbench, with two guide rods installed on its both sides. Rotation of the handwheel drives the vertical elevation of the V-block assembly, enabling precise positioning of test specimens of different sizes and shapes.
