Overview

Metal material drop hammer impact testing machine No.: Brand: Shanghai Lingye Instrument Specification: Type: Drop hammer (ball) impact testing machine Introduction: This drop hammer impact testing machine is mainly used to determine the non plastic transition temperature of ferritic steel (including plates, profiles, cast steel, and forged steel). The non plastic transition temperature characterizes the highest temperature at which steel containing small cracks undergoes brittle fracture under dynamic loading yield stress. This impact testing machine integrates mechanical, electrical, and automatic control technologies, achieving a fully automated process of feeding, lifting, impact, sampling, and grabbing the hammer. In addition, the testing machine is equipped with multiple protective measures, greatly improving the safety of operators and equipment use. This machine is a commonly used testing instrument in various large and small steel mills, steel research institutes, and other enterprises and scientific research units.

IIMetal drop hammer impact testing machineMain features:

1. It has automatic sample delivery and positioning functions, easy operation, and high work efficiency.
2. The rack adopts a frame structure, with 4 columns connecting the bottom plate and top plate. The bottom plate is made of solid steel plate processing, fully ensuring the stability of the testing machine during impact.
3. The hammer body is made of high-strength integral steel plate, which has high impact resistance.
4. The self-locking device of the grab and release hammer immediately locks itself after grabbing the hammer, which will not cause accidents under the action of gravity and will not open in case of accidental power failure, ensuring high safety.
5. It has a fully enclosed protective net and multiple safety protection devices to fully ensure the safety of the test personnel.
6. A dedicated anvil replacement tool that is easy and convenient to replace.
7. Intelligent control system that alerts for faults; If the sample is not in place, the hammer head is not self-locking, the protective device is not closed, and the hammer head is not lifted properly.
8. Equipped with Siemens programmable controller and touch screen control, it has high reliability, strong anti-interference ability, strong universality, adaptability, scalability, and low maintenance workload.
