Abstract

The invention relates to a sample feeding apparatus, which comprises a frame, wherein a sample loading platform is arranged at the front portion in the frame, the middle portion in the frame is provided with a low temperature box, the sample loading platform is arranged in the low temperature box, a sample feeding mechanism is arranged above the frame and can complete actions such as sample feeding, sample grasping and sample placing, and the sample feeding apparatus further comprises a sample feeding driving mechanism capable of driving the sample feeding mechanism to move on the frame. The invention further discloses a drop hammer impact test machine. According to the present invention, the sample feeding apparatus capable of automatically completing low-temperature cooling, sample feeding and testing without manual operation and having characteristics of short test time and high test efficiency, and the drop hammer impact test machine thereof are provided.

Description

technical field [0001] The invention relates to the field of impact testing machines, in particular to a sample feeding device and a drop weight impact testing machine thereof. Background technique [0002] Drop-weight Tear Test (DWTT for short) is a method for testing the toughness of pipeline steel materials. The main purpose of the test is to establish the relationship between fracture morphology and temperature, so as to determine the brittle transition temperature of pipeline steel materials. , to ensure that the pipeline works in the ductile temperature zone and avoid brittle fracture accidents. The specimen fracture characteristics of this test are very similar to the fracture propagation fracture characteristics of the pipeline when it is physically damaged, so it is widely used in the toughness evaluation of pipeline steel and is used as one of the quality acceptance indicators of pipeline steel. [0003] The brittle transition temperature is the temperature range ...
