Find here details of Automatic Stirrup Bender on our website. Today we would like to talk about what is the root cause of the vibration generated by the CNC bending machine.
The fundamental reason for the vibration is that the numerical control bending device itself and its surrounding medium are excited by the vibration source, and the excitation comes from two kinds of factors. One is the defect of the rotating part or the reciprocating piece.
The main drawbacks are shared by professional Stirrup Bender Manufacturer:
1. Imbalance, that is, the mass distribution with respect to the axis of rotation is uneven, and I generate sexual force during operation to constitute excitation.
2. The impact of the reciprocating member, such as the numerical control bending device with the principle of the plane linkage mechanism, the inertial force generated by the reciprocating motion of the connecting rod, the direction of which changes periodically, forming an impact effect. This is difficult to avoid structurally.
3. The rotor is bent and deformed, and the parts are lost. The mass distribution is uneven, and the centrifugal inertia force is generated during the rotation, resulting in vibration.
4. The manufacturing quality is not high, especially the positional accuracy of the parts or components is not high, which is one of the reasons for the quality imbalance.
5. Loose parts on the rotating body increase the uneven distribution of mass, and the gap between the shaft and the hole increases the imbalance due to the increased wear. The second is the structural factors of the CNC bending machine equipment.
This factor mainly includes:
1. Gear gears are not well meshed due to manufacturing errors, and the force between the teeth changes periodically in magnitude and direction. As the gear wear and pitting corrosion in operation become more and more serious, this periodic excitation is also getting worse.
2. Unreasonable structure of the coupling and clutch brings imbalance and impact.
3. Oil film whirl and oscillation of the sliding bearing.
4. Rolling element imbalance and radial clearance in rolling bearings.
5. The base is twisted.
6. Power supply excitation.
7. Pressure pulsation and so on.
