Features
- Fully automated operation
This impact testing machine configuration supports automatic specimen feeding, impact execution, pendulum lifting, and specimen removal, enabling a true fully automated workflow. - Heavy-duty base and frame
A high-strength carbon-steel base combined with a 300x300 H-beam steel frame delivers outstanding rigidity and structural stability. This architecture effectively absorbs impact-induced vibration. The specimen anvil is manufactured from 45# steel (forged and tempered), offering excellent strength and high measurement accuracy. - High-strength pendulum
Engineered for high axial and lateral stiffness, the pendulum ensures consistent and reliable energy transfer during each impact. The swinging pendulum assembly includes: Pendulum body, arm, hook, and striker. The pendulum arm is machined from 45# steel into an H-beam profile. The body and the arm are fully tempered for enhanced structural integrity. The striker is made from hardened tool steel, reaching a hardness of ~62 HRC, providing exceptional wear resistance. - Three impact energy levels
Multiple selectable energy levels can be achieved without changing the pendulum, offering greater convenience and improved test efficiency. - Automated specimen feeding and positioning system
A system designed for fast, precise, and safe specimen handling Workflow:
① Specimen placed on the feed table;
② Positioning cylinder sets specimen length;
③ Transfer cylinder moves the specimen to the pre-support zone;
④ Loading cylinder pushes the specimen into the final test position;
⑤ All cylinders automatically return to default positions - Robust specimen support assembly
A combined support-block and anvil structure provides high load-bearing capability. The anvil is produced from hardened Cr-Mn steel (58-62 HRC), ensuring stable support under high-energy impact conditions. - Siemens-based control platform
A Siemens S7-200 PLC provides reliable control logic, a high degree of automation, reduced operator workload, and improved productivity and operational safety.
