Drop hammer impact testing machine - Determination of impact resistance of pipe and sheet products

The main structure and principle of the testing machine

1) The testing machine mainly consists of a workbench, a secondary impact prevention mechanism, a guide tube, a hammer body, a hammer body lifting and automatic falling mechanism, a motor, a reducer, an electrical control box, a machine base, etc.

2) Working principle of testing machine:

On the lifting mechanism of the testing machine that can be raised and lowered, there is an electromagnet installed to control the falling hammer and impact the specimen to achieve the testing purpose. The impact energy can be calculated based on the mass of the hammer and the impact height. When the hammer impacts the sample and the sample does not break, causing the hammer to rebound, the photoelectric signal controls the hammer holding mechanism to quickly catch the rebound hammer, achieving the goal of preventing secondary impact.

Installation of testing machine

After disassembling the testing machine, place it on the foundation with the foot screws and adjust the bottom surface of the machine base to achieve the lead hammer degree of the guide tube1/1000Tighten the anchor screws and adjust the gap between the hammer body and the guide pipe, ensuring that the hammer's forward, backward, left, and right swing within the guide pipe is less than ±2.0Mm. Inject lithium based grease into the gearbox. Connect the cables between the control box and the host, and connect the power supply.

Main technical parameters

1. Usage temperature:10℃～35℃；

2. Center deviation of impact point ≤2.5mm；

3. There are no large vibration sources or strong electromagnetic fields nearby;

4. There is no corrosive medium in the environment, and attention should be paid to ensuring good ventilation in the electrical control box;

5. Power supply: AC220V±10％5A 50Hz；

6. Hammer mass: see attached table

7. Applicable pipe diameter:20mm～450㎜；

8. Hammer head:SR5TheSR10TheSR30TheD25TheD90

9. Impact height:50～2000㎜；

10. Height positioning error: ±2㎜；

11. Dimensions: Host (length x width x height)760㎜×700㎜× 3800㎜Whole machine weight: approximately550㎏。

This testing machine can preset the impact height, automatically lift the hammer, automatically drop the hammer, and automatically prevent secondary impact. The whole machine has a good structure, high rigidity, and high precision and reliability.
