4.Performance Description

◆The main frame and base are both made of cast structure, with high overall rigidity and stability. The energy absorbed by the body is small, and the measurement results are closer to the actual absorbed work of the sample.

◆The main machine adopts high-rigidity design, and each force-bearing component has been analyzed and designed by finite element, and has been precision processed and tested;

◆The machining center processes the front and rear bearing holes and anvil mounting positions at one time to ensure that the front and rear bearing holes are symmetrical and the distance from the balance axis axis to the striking point is accurate;

◆The pendulum main shaft is supported by front and rear double bearings, with reasonable load distribution, which reduces the lateral vibration of the pendulum during impact;

◆The forces on the front and rear bearings of the balance shaft are balanced, which reduces friction and reduces impact damage to the bearings;

◆Imported high-precision bearings with low friction, impact resistance and long life;

◆The swing rod is a thick-walled seamless tube with high stiffness and no deformation, which reduces energy absorption;

◆The round body of the pendulum is precisely designed with three-dimensional software and has an accurate center of gravity; its circular structure effectively reduces air resistance energy loss during impact;

◆The impact blade is made of special materials, with high hardness, small deformation and impact resistance;

◆It can be equipped with two specifications of impact blades, 2mm and 8mm (choose one), and the impact blade is fixed by screw compression, making replacement simple and convenient;

◆The sample anvil (sample support jaw) is processed with special materials and special technology to ensure that the edge is strong and rounded, the plane and arc tangent transitions are impact-resistant and wear-resistant;

◆Using the electromagnetic clutch produced by introducing advanced foreign technology, it can engage and separate quickly without slipping;

◆Operation control is carried out through the PLC system, which automatically controls the entire test process of raising the pendulum, hanging the pendulum, impacting, and placing the pendulum. The operation is reliable and the electrical failure rate is greatly reduced;

◆The pendulum is controlled by PLC at a preset angle, with accurate positioning and never changes, ensuring constant initial impact energy;

◆The pendulum hanging device adopts a buffer mechanism, and the hanging pendulum is stable and vibration-free, avoiding impact and damage to the hanging pendulum mechanism;

◆The electric drive gets rid of the impact cleanly, ensuring that the initial impact energy and initial speed are not affected;

◆After the impact is completed, the remaining energy is used to automatically hang the pendulum again to prepare for the next impact and improve work efficiency;

◆The initial energy level can be adjusted by replacing the pendulum and the range of use can be expanded;

◆Can be operated through microcomputer interface or manual control box;

◆Through the high-precision photoelectric encoder to accurately test the angle, the computer calculates the impact absorption energy, which greatly improves the testing accuracy of impact energy;

◆Two energy display methods: dial and microcomputer display, the results can be compared with each other;

◆The software is designed with automatic calibration function, which can test friction energy loss and air resistance energy loss;

◆Equipped with automatic sample output mechanism. After the impact is completed, based on the preset criteria, the measurement and control system can automatically determine whether it is qualified and automatically pick them out separately;

◆Independent electrical control cabinet, complete isolation of strong and weak electricity to reduce interference;

◆Equipped with a safety pin, the safety pin pops up automatically after the pendulum rises to the predetermined position to prevent accidents caused by the pendulum falling accidentally;

◆The whole machine is equipped with a split combined openable fully enclosed protective cover and an aluminum alloy tempered glass structure, which is safe and beautiful; it is equipped with an access control switch, and the impact can only be carried out when the door is closed, which plays a safety role;

5. Operation control system and measurement display system

(1) Operation control system:

The operation is controlled by Siemens PLC, and the hammer is lifted through a two-stage reducer and electromagnetic clutch. During the test, first click to take out the pendulum through the microcomputer interface or touch screen. The PLC instructs the clutch to engage and the reduction motor to start, driving the pendulum to rotate counterclockwise and rise. When it reaches the predetermined angle, the PLC instructs the motor to stop, the clutch to disengage, and the pendulum to hang up. The pendulum device catches the pendulum hook, and the safety pin automatically extends, ready for impact. When the sample is placed, click the unpin first to retract the safety pin, and then click the impact. The traction electromagnet quickly pushes the hook to disengage, and the pendulum falls freely clockwise to impact the sample.

After the sample is broken, when the pendulum uses the remaining energy to return to the highest point in the forward direction, the PLC instructs the electromagnetic clutch to engage and the motor to start, and then drives the pendulum up counterclockwise. When it reaches the predetermined angle, the PLC instructs the motor to stop and the clutch to disengage. , the pendulum hanging device hangs the pendulum hook, and the safety pin automatically extends, which completes one impact cycle and is ready for the next impact. After the sample impact is completed, the broken sample falls on the recovery belt, and the qualified or unqualified samples are transported to different recovery devices according to the preset criteria.

The system has strong anti-interference ability, stable operation, safe and reliable.​
