The equipment mainly consists of a main frame, jaw device, pendulum device, hanging pendulum device, transmission system, brake device, sample recovery device, safety protection device, electrical control system, safety pin device and other parts
Each part has the following advantages:
Host rack:Adopting gray iron integral casting, it has high strength, good rigidity, and can effectively absorb the vibration generated by the impact sample, making the equipment run more smoothly. After the casting is completed, it is clamped and processed in one go on the CNC machining center to avoid cumulative processing errors caused by multiple clamping, with high accuracy, low equipment energy loss, and accurate measurement results.
Jaw device:The parallelogram structure strictly meets the standard requirements for key dimensions and comes with a calibration certificate. It can be used repeatedly four times by changing the orientation, with a long service life and unchanged span. Fixed with three screws, easy to disassemble and assemble, high stability, and high testing accuracy. MTS Metes E22.152 Pendulum Impact Tester
Pendulum device:3D software design and specialized software analysis accurately ensure the torque and impact center position of the pendulum, providing strict guarantees for the accuracy of detection data. The side of the pendulum is designed with a sloping surface corresponding to the shape of the anvil, greatly reducing the probability of sample jamming.
Hanging device:Cylinder driven, stable action, low noise, with self-locking function, can maintain the hanging state even if the power is cut off. Equipped with a buffer to avoid the impact of the hanging process on the host, the action is smooth and the noise is low.
Transmission system:Special precision bearings for pendulum, high precision, low energy loss, specially customized tooth embedded clutch, optimized tooth profile design, smooth separation and coupling process, long service life. Adopting imported two-stage reducers and motors, the operation is smoother and more stable. MTS Metes E22.152 Pendulum Impact Tester
Braking device:Disc brake has the advantages of fast braking speed, no axial force, and low noise. It is designed with normally closed control and automatically brakes after power failure, ensuring safe operation of the equipment.
Sample recycling device: A high-quality rubber belt driven by a rotating motor is used as the sample recycling device. The testing machine is equipped with a fully enclosed protective net. After the sample impact is completed, the broken sample falls onto the recycling belt. The recycling device will automatically operate after the impact is completed, taking the waste sample out of the testing machine to prevent testing personnel from entering the testing machine to recycle the waste sample. This not only improves work efficiency but also enhances the safety of testing personnel.
Safety protection device:New exterior design, fully enclosed aluminum alloy structure, more beautiful appearance, equipped with access control switch. When the protective cover is not completely closed, the equipment will not move, effectively protecting the safety of the operator and improving the safety of the equipment. The protective cover is equipped with a door closing impact function, which can reduce operating steps and improve testing efficiency.
Electrical system: A stable performance PLC is used as the control core, combined with a 7-inch touch screen as the display and operation terminal, relying on high-precision encoders to obtain real-time position of the pendulum. The electrical system runs stably and the data is reliable and accurate.
Safety pin device:Equipped with an induction switch, the device does not perform any action when the safety pin is extended. Effectively improve the safety protection of debugging in the hanging state
