lIntegrated design of main machine and base, with overall casting and processing, high rigidity and good stability.
lDouble-support frame structure, with the pendulum spindle supported by a simply supported beam. The front and rear bearing holes are symmetrical to ensure the accurate distance from the pendulum axis to the striking point.
lThe pendulum rod is made of thick-walled seamless steel pipe, featuring high rigidity and no defor- mation.
lThe impact blade is made of special materials, having high hardness, small deformation and impact resistance.
lEquipped with two types of impact blades with specifications of 2mm and 8mm (optional), which are fixed by screw compression and easy to replace.
lA two-stage reduction motor is used as the power for lifting the hammer, with large torque, no slip- page and low noise.
lImported electromagnetic clutch is adopted, which engages and disengages quickly without slippage. Controlled by a microcomputer, it automatically measures and records, and automatically controls the entire experimental process of pendulum lifting, hanging and releasing.
lThe pendulum hanging is controlled by the system according to the preset angle, with accurate posi- tioning to ensure the constant initial impact energy.
lThe pendulum hanging device adopts a hydraulic buffer mechanism, which enables stable pendulum hanging without jitter, avoiding impact and damage to the pendulum hanging mechanism.
lThe software has an automatic calibration function, which can test the energy loss caused by friction and air resistance.
lSample recovery device (optional): after the impact is completed, the broken samples are transported to different recovery devices through a recovery belt.
lAutomatic feeding function (optional): samples are directly pushed to the appropriate position of the equipment, and subsequent experiments can be carried out directly.
lApplicable standards: GB/T 2611, JB/T 7406.1, GB/T 3808, GB/T 229, JJG 145, ISO 148, ASTM E23,
GB/T 18658, JB/T 6147
Product Application：
lDeformed steel bars for construction and structural steel for bridges: It is necessary to verify their fracture resistance under low temperature or sudden load.
lTest the impact toughness of steel used for automobile body frames and excavator buck- ets to ensure that the materials do not break easily during collision or heavy load impact. Conduct impact tests on titanium alloys used for aero-engine blades to ensure that they can withstand air flow impact without failure during high-altitude and high-speed opera- tion.
