1、 Equipment name: Microcomputer controlled low-temperature fully automatic impacttesting machine

2、 Type number:JB-W300CYZ

3、 Performance Description:

This impact testing machine is used to test the resistance of metal materials to impact at low temperatures. It is an essential testing instrument for metallurgical, mechanical manufacturing, and other units, as well as an indispensable testing instrument for research institutions conducting new material research.

1. This machine adopts PLC control, and the swing, hanging, feeding, positioning, impact, and temperature adjustment settings are all electrically and mechanically controlled. Equipped with a dedicated feeding device for automatic feeding and automatic end face positioning of samples. The time from the sample being taken out of the furnace to impact shall not exceed 2 seconds, meeting the requirements of the low-temperature Charpy impact test method for metals. After impacting the sample, the remaining energy can be used to automatically swing and prepare for the next test, resulting in high work efficiency;

2. The host adopts a double support column, with a simply supported beam and hanging pendulum for the main shaft. The radial load distribution of the bearings is reasonable, effectively reducing the deformation of the main shaft and greatly reducing the energy loss caused by bearing friction;

3. Adopting a two-stage standard deceleration motor to lift the hammer, it runs smoothly;

4. The hanging device adopts hydraulic buffering, ensuring smooth hanging;

5. The precise design of the pendulum 3D software ensures accurate impact center and precise pendulum torque;

6. The impact knife is fixed with screws for easy replacement;

8. The host is equipped with safety protection pins and a safety net to ensure the safety of the test;
