Working principle of JB-30A impact tester

Jinan Hengsi Shanda Instrument Co., Ltd. is a manufacturerImpact testing machineThe following is an important manufacturer of JB-30A impact test machine using the pendulum type impact test principle to conduct impact test on the sample. The swing, swing, impact, and braking processes are mechanical and electrically controlled and are semi-automatically operated.Testing machine. The button box of the JB-30A type impact test machine is equipped with three buttons: "swing arm drop", "impact" and "pendulum clamp". Press the "Impact" button, the solenoid is energized, the magnet core moves and drives the connecting rod, so that the lever swings back and leaves the hook, and the pendulum is the free fall of the impact sample. When swinging, press the "Swing Arm Down" button, the motor is powered on, and the transmission system drags the raised arm down. When the limit switch on the raised arm touches the swing rod, the electromagnet is powered off. Under the action of spring force, the pin pops out of the pin seat and extends into the hook on the swing rod. At the same time, the motor reverses and the arm lifts to driveImpact testing machinethe pendulum rises.
