The JL-3000 Drop Hammer Ball Stud Bending Impact Test Machine developed and manufactured by Liangong is suitable for the ball stud shaft impact bending test in the global industry standard of the automobile industry. It is composed of frame part, lifting system, hammer body, single row ball stud mounting support, safety protection system and control system.

  The machine can adjust the impact energy by adjusting the number of weights and adjusting the impact height. The sample is accurate and fast to centering, and the energy range is steplessly adjustable, and the energy automatic display function is available. High degree of automation, multi-channel safety protection mechanism, safe and reliable.

The 3000J drop hammer impact tester mainly includes the following parts:

The machine is designed with a complete and reliable safety protection system, including: protective net, hook in place detection, power failure protection, upper limit protection.

1. Protective net: A protective net is provided in the four directions of the main anvil to prevent the flying object from injuring people.

2. Detection of hook in place: The self-locking hook of the machine has high self-locking property from the structural principle. In order to further improve its safety, the machine is equipped with a detection device beside the lock cylinder for judging whether the hook is in place. If the hook is not in place, the lift motor will not move in the direction of the lift hammer.

3 Power-off protection: When a certain part of the host fails or needs to be disassembled, once the protective net is open, the electrical control system of the machine will be in a stop state and will not accept any instructions.

4. The upper limit safety system is composed of photoelectric encoder and mechanical limit switch. The lifting stroke of the machine is large. In order to avoid the “crash” phenomenon caused by inadvertent operation, the machine has a travel switch at the maximum stroke. The extreme position will automatically stop.
