Metal drop hammer impact tester - edt2000 series
Function purpose:
It is mainly used for drop weight tear test of pipeline steel and medium thick steel plate ferritic steel, i.e. DWTT Test. The testing machine integrates machine, electricity and automatic control technology, and realizes the whole automatic process of feeding, lifting hammer, impact, fracture sample collection and grasping hammer. In addition, the tester is equipped with multi-channel protection measures, which greatly improves the safety of operators and equipment. This machine is a common testing instrument used by pipeline steel manufacturers, large steel mills, iron and steel research institutes and other enterprises and scientific research institutions
Functional features:
It adopts servo motor to lift the clock, with high control accuracy and accurate positioning. The acceleration and deceleration process of the servo motor can reduce the impact on the motor.

1. Adopt servo motor to lift hammer, with high control accuracy and accurate positioning. When the lifting hammer
and lifting hammer are in place, there is a process of acceleration and deceleration of the servo motor, which can
reduce the impact on the motor;
2. Siemens PLC equipped with Taiwan touch screen control has the advantages of high reliability, strong anti-
interference ability, versatility, adaptability, expansibility, small maintenance workload, etc;
3. It has the functions of automatic sample sending and positioning, easy operation and high working efficiency;
4. The main frame adopts the upper and lower split column structure, and there are four columns in total. The
bottom plate is made of the whole solid steel plate, which fully guarantees the stability of the testing machine
during the impact;
5. The hammer body is processed in a separate way, each of which is made of high-strength integral steel plate,
with high impact strength, so that it will not fracture due to casting defects;
6. The hammer body is lifted by the anchor chain. Compared with the ordinary steel wire rope, the elasticity of the
anchor chain is small, so that the height measurement is more accurate. Moreover, the anchor chain has high
strength, is not easy to wear, and is safer than the steel wire rope;
7. The hammer grabbing device of the testing machine is a specially designed self-locking device, which will lock
itself immediately after grabbing the hammer. Under the action of gravity, there will be no accident, and it will not
open when the power is cut off accidentally, so it has high safety;
8. The sample sending frame of the sample sending device is processed as a whole, without welding and with high
strength. Equipped with sample clamp block, the clamp block is quenched with high quality steel, with high
surface hardness and strong wear resistance. Dovetail groove is used between clamp block and clamp block seat
for convenient replacement;
9. Specially designed and customized buffer cylinder according to the characteristics of drop hammer tear impact,
with high buffer energy, high impact resistance speed and symmetrical arrangement, can effectively absorb the
remaining energy of drop hammer, reduce the impact on equipment and prolong the service life of equipment;
10. It has a sample recovery device, which can take the waste sample out of the testing machine and prevent the
tester from entering the inside of the testing machine to recover the waste sample, which not only improves the
working efficiency, but also improves the safety of the tester;
11. The drop hammer impact tester has a fully enclosed protective net and multiple safety protection devices, which
fully guarantees the safety of the tester;
12. The intelligent control system can alarm the following faults: the sample is not in place, the hammer is not self-
locking, the protective device is not in place, the hammer is not lifted in place, etc.
