Versatile Drop Hammer Test Equipment
Ideal for quality control and product development in manufacturing and engineering applications, this precision testing equipment delivers reliable impact performance evaluation.
Product Overview
The drop hammer impact tester, also known as drop weight tear test equipment, is specifically designed for impact performance testing of plastic pipes, sheets, and finished products. This equipment accurately verifies the anti-impact mechanical properties of various materials.
Key Features
- Digital control system for automated operation
- Automatic parameter setting, zero calibration, and hammer procedures
- Prevents secondary impact interference during testing
- Ensures standardized and accurate test results
Product Structure & Working Principle
This tester consists of a work platform, anti-secondary-impact assembly, support barrel, guide conduit, falling hammer mass, V-shaped fixture, auto drop-hammer actuator, speed reducer, electrical control cabinet, and support frame.
Operating principle: A hammer-holding fixture within the guide conduit lifts the hammer body to the predefined test height using a motor-reducer assembly. Upon triggering the release switch, the hammer falls freely along the conduit and strikes the test specimen to complete impact measurement.
Impact energy is computed from hammer mass and drop height. The anti-rebound mechanism, triggered by photoelectric sensing signals, captures the rebounding hammer to eliminate secondary-impact occurrences.
V-shaped iron fixtures beneath the work platform feature guide lead screws on lateral sides. Manual rotation of the handwheel actuates the V-shaped iron lifting unit for height adjustment.
