1. Performance description:

JB C DW-Z300 C /500 C/750C microcomputer controlled automatic low temperature impact tester , used to test the resistance of metal materials to impact under dynamic load. It is a necessary testing instrument for metallurgical machinery manufacturing and other units as well as scientific research units of new materials research indispensable test instrument , the series of models on the market today is the most new impact tester.

    The machine is composed of an impact testing machine , a liquid nitrogen cooling device, and an automatic feeding and positioning device. It is used to accurately test and analyze the impact resistance of materials at low temperatures. The cryogenic device adopts liquid nitrogen tank for refrigeration, the cooling temperature can reach -190° C , the refrigeration speed is fast, the temperature is automatically controlled, and the alarm is automatically prompted. Pneumatic or electric feeding and positioning, fast speed and accurate positioning.

2. Technical characteristics of J B CD W -Z 300 C /500 C/750C microcomputer controlled impact testing machine:

1. The machine adopts fully automatic control .  The equipment for raising and hanging pendulum, feeding, positioning, impact and temperature adjustment are all electrical and mechanical control, equipped with a special feeding device for automatic feeding, and automatic section positioning of the sample. The time from the sample out of the furnace to the impact is no more than 2 seconds, which meets the requirements of the metal low-temperature Charpy impact test method. After impacting the sample, the remaining energy can be used to automatically swing the pendulum to prepare for the next test, and the work efficiency is high .

2.  J BCD W-Z 300C /500C/750C microcomputer-controlled impact testing machine has a single-support column structure, a cantilever hanging pendulum, and a U-shaped pendulum; the main frame base and the column are integrated design, integrated casting processing, good rigidity To improve the stability of the test;     

3. The  pendulum shaft is supported by simply supported beams, and the radial load distribution of the bearing is reasonable, which greatly reduces the energy loss caused by bearing friction .

4. The  impact knife is installed and fixed with screws, which is simple and convenient to replace;

5.  Sample simply supported beam support; fully enclosed protective net;

6. The  host of the J B CD W -Z 300 C /500 C/750C microcomputer-controlled impact testing machine is equipped with safety protection pins and a fully enclosed safety protection net;

7. The  J B D W -Z 300 C /500 C/750C microcomputer-controlled impact testing machine is semi-automatically controlled. The swing, hanging, impact, and placement are all electrically controlled, and the remaining energy after breaking the sample can be used The automatic pendulum is ready for the next experiment. It is especially suitable for laboratories that continuously do impact tests and metallurgy and machinery manufacturing departments that do a large number of impact tests; the testing machine complies with GB/T229-2007 "Charpy Pendulum Impact Test for Metallic Materials" Methods" GB/T3808-2002 "Inspection of Pendulum Impact Tester" and GB4158-84 "Metal Izod Impact Test Method" require the impact test of metallic materials.
