Plastic transition temperature drop hammer impact test machine
Plastic transition temperature drop hammer impact test machine
Product Description:
This test machine is suitable for conducting non-plastic transition temperature test of ferrite steel. The non-plastic transition (NDT) temperature refers to the temperature at which the standard sample breaks when tested according to ASTM E208-2006 and GB/T 6803-1986. It characterizes the temperature at which the steel containing cracks undergoes brittle breaking under dynamic loading yield stress.
It consists of a frame, lift, hammer, anvil, safety protection and control system. The machine uses the method of adjusting the amount of counterweight thallium and adjusting the impact height to adjust the impact energy, and has the functions of preventing secondary strikes and automatic sample delivery. The sample is accurately and fast, the energy range is steplessly adjustable, and it has an energy automatic display function.
The test machine can adjust the impact energy by configuring different hammer weights and changing the lifting height. The impact energy can be preset and the lifting height can be controlled.
The test machine is equipped with manual and electric automatic sample delivery and positioning mechanism. The span of the sample support table can be adjusted to meet the span requirements of different samples.
The test machine is provided with a device to prevent secondary impact of the hammer. A safety insurance mechanism and safety protection device are provided.
The test machine can be equipped with a low-temperature device of 40℃~-100℃.
