The client is a professional enterprise engaged in the research, development, and production of automotive injection molds, engineering machinery parts, and forgings. Its products have long been used as supporting components for multiple domestic automobile brands such as BYD, Ideal, Geely, and Leap. With the continuous improvement of OEMs' requirements for part quality, the client needs to conduct rigorous impact toughness testing on the mold steel and forgings it uses to ensure the safety and reliability of its products during use.
Inspection point:
1. Low efficiency of manual operation: Traditional impact testing relies on manual sample loading, pendulum swinging, and data reading, which results in low efficiency during batch testing, and human errors are difficult to avoid.
2. Insufficient accuracy in low-temperature testing: For components that need to operate in a low-temperature environment, old equipment exhibits unstable temperature control during sample transfer, affecting the accuracy of test results.
3. Weakness in sample preparation: The precision of notch machining for impact test samples directly determines the test results, and the notches machined by the original manual broaching machine exhibit poor consistency.
4. Data management is lagging behind: The experimental results rely on manual recording, which is not conducive to quality traceability and report issuance.
Core advantages:
1. Fully automatic closed-loop control, one-click completion: Utilizing PC microcomputer control, it achieves full automation of the entire process from swinging → positioning → impacting → measuring → calculating → displaying results → printing. After impacting the sample, the remaining energy can be used to automatically swing, preparing for the next test, making it particularly suitable for continuous batch testing.
2. Multiple impact energies available: It offers a range of impact energy specifications, including 150J, 300J, 450J, and 750J, catering to the impact toughness testing needs of materials ranging from conventional die steel to high-strength alloy steel. The pendulum has a pre-swing angle of 150° and an impact speed of 5.2m/s, suitable for standard Charpy V-notch or U-notch specimens.
3. High-precision measurement and control, reliable data: Equipped with a high-precision angle encoder and measurement and control system, the test results are precise, reliable, and have good repeatability.
4. Scalable cryogenic module: The equipment can be equipped with a cryogenic device, utilizing cascade compressor refrigeration technology, covering a temperature range from room temperature to -100℃ with a temperature control accuracy of ±1.5℃. Equipped with a dedicated automatic sample feeding device, it ensures that the time from sample egress to impact is no more than 2 seconds, fully meeting the requirements of the metal Charpy impact test method at low temperatures. The sample box has a capacity for 20 samples, enabling continuous unattended testing.
5. Multiple safety protections: Equipped with multiple safety measures such as overload protection, overcurrent protection, limit protection, and emergency stop buttons, ensuring the safety of operators.
6. Intelligent software system: The measurement and control software operates on the Chinese Windows platform, displaying test data in real-time, automatically calculating impact absorption energy, and capable of generating test reports compliant with GB/T229 standards with a single click. It supports exporting in various formats such as Word, Excel, and PDF.
