JB-W Series Computer-Controlled Impact Testing Machine
The JB-W Series Impact Testing Machine is designed to determine the impact resistance performance of metallic materials under dynamic loads, enabling the evaluation of material properties under dynamic conditions. Developed in accordance with the national standard GB/T3808-2018 "Verification of Pendulum Impact Testing Machines" and GB/T229-2020 "Metallic Materials - Charpy Pendulum Impact Test Method", the machine tests standard specimens with a cross-section of 10×10mm. With substantial impact energy capacity, it is primarily used for testing ferrous metals with high impact toughness, such as steel and its alloys.
Product Details
The JB-W model is a computer-controlled pendulum impact testing machine that utilizes PC computer systems and highly reliable PLC controllers to manage the testing process. It features electric pendulum lifting and impact mechanisms, with computer-based measurement, calculation, screen display of results, and printing capabilities, ensuring high efficiency and precision. After impacting the specimen, the machine automatically lifts the pendulum using residual energy, preparing for the next impact test. This makes it particularly suitable for laboratories requiring continuous impact testing such as metallurgy and machinery manufacturing that conduct large-scale impact tests. The system can display material impact absorption energy, impact toughness, pendulum angle, and average test values, while generating test reports. Additionally, it supports remote data transmission based on user requirements.
Main Features
Software and Operating System Advantages:
Simultaneous display on computer and dial with synchronized data, featuring dual operating systems that allow operation either through computer mouse or control panel buttons without interference, ensuring flexible operation and high efficiency.
Capable of continuous testing of hundreds of specimens with minimal manual intervention - operators only need to place specimens and press action buttons, while all other operations are automated, significantly reducing labor intensity and eliminating manual data recording errors.
pendulum impact testing software automatically records test results in a database for storage and retrieval. The software runs on Windows 7 system with Chinese window interface consistent with Windows style. All test operations including pendulum lifting, pin withdrawal, impact, and pendulum release can be completed via mouse input or clicks on the computer screen.
Electrical Control Advantages:
Uses imported PLC controllers as the core of the electrical control system, with high-precision photoelectric encoders as angle acquisition sensors.
Integrated circuit board design simplifies maintenance and repair.
Brush clutch replaces traditional clutches, enabling automatic pendulum positioning during testing, effectively protecting the clutch system and extending service life.
Safety Advantages:
Semi-enclosed protective cover made of high-toughness material encloses the entire pendulum trajectory, preventing injury from flying specimen fragments and ensuring operator safety.
