The busbar cutting machine in the use of the process may appear some faults, busbar cutting machine electrical fault analysis process is also the troubleshooting process, so some common troubleshooting methods of copper bus bar machinery electrical fault.

1、 Power supply of the busbar cutting machine.

The power supply is the energy source for the normal operation of the maintenance system and even the whole machine tool. If it fails or fails, the data will be lost and the machine will be shut down. If it is serious, it will destroy part or even all of the systems.

 

Due to the sufficient power and high quality of power grid in western countries, the power supply design of their electrical system is less considered, which is slightly insufficient for the power supply network with large fluctuation and high harmonic in China. In addition, some man-made factors will inevitably lead to faults caused by the power supply.

2、 CNC system position ring fault of busbar processor.

 

a.Position ring alarm. It may be that the position measurement circuit is an open circuit. the measuring element is damaged. the interface signal established by position control does not exist.

 

b.The coordinate axis moves without command. It may be that the drift is too large; the position loop or speed loop is connected with positive feedback; the feedback wiring is open; the measuring element is damaged.

 

c.The machine coordinate can not find the zero point. It may be that the zero direction is far away from the zero points; the encoder is damaged or the wiring is open; the grating zero marks are shifted; the zero return deceleration switch fails.

 

d.The dynamic characteristics of the machine tool become worse, and the machining quality of the workpiece decreases.

One of them may be caused by excessive clearance or even serious wear of mechanical transmission system or insufficient lubrication or even wear of guide rail.

For the electrical control system, it may be that the speed loop, position loop, and related parameters are not in the best matching state, so the optimal adjustment should be carried out again after the mechanical fault is basically eliminated.

e. Accidental shutdown failure

There are two possible scenarios.

One case is that the problems in the relevant software design as mentioned above cause the shutdown failure under some specific combination of operation and function operation. In general, the machine tool will disappear when it is powered on again after power off.

The other is caused by environmental conditions, such as strong interference (power grid or surrounding equipment), high temperature, excessive humidity, and so on. This kind of environmental factors is often ignored by people. For example, in southern China, machine tools are placed near ordinary workshops, or even close to open doors, electrical cabinets open for a long time. And there are a large number of equipment producing dust, metal chips or water mist.

The fault analysis process of copper bus bar machinery is also the troubleshooting process, which has the following points.

(1) CNC system position ring fault

  1. Position ring alarm. It may be that the position measurement circuit is open circuit. The measuring element is damaged; the interface signal established by position control does not exist.

 

  1. The axis moves without command. It may be that the drift is too large; the position loop or speed loop is connected with positive feedback. The feedback wiring is open, and the measuring element is damaged.

 

  • The power supply is the energy source for the normal operation of the maintenance system and even the whole machine tool. Severe damage will destroy part or even all of the systems.

 

  • Busbar cutting machine in the use of the process may appear some faults. Busbar cutting machine electrical fault analysis process is also the troubleshooting process. So some common troubleshooting methods of busbar cutting machine electrical fault.

(2)The power supply.

The power supply is the energy source for the normal operation of the maintenance system and even the whole machine tool. Severe damage will destroy part or even all of the systems. Therefore, in the design of the CNC system, we should try our best to.

 

An Independent distribution box shall be provided instead of being used in series with other equipment.

 

The area with poor power supply quality should be equipped with a three-phase AC voltage stabilizing device.

 

The starting end of the power supply is well-grounded.

 

Three-phase five-wire systems should be adopted for a three-phase power supply entering the CNC machine tool. And neutral line (n) and grounding (PE) should be strictly separated.

 

The layout of electrical components in the electrical cabinet. And the laying of AC and DC wires should be isolated from each other.

And more:

(3) The machine coordinate cannot find the zero point. It may be that the zero direction is far away from the zero points. The encoder is damaged or the wiring is open. the grating zero marks are shifted. the zero return deceleration switch fails.

 

(4) The dynamic characteristics of the machine tool become worse. And the machining quality of the workpiece decreases and even the machine tool vibrates at a certain speed. One of them may be caused by excessive clearance or even serious wear of the mechanical transmission system.

Or insufficient lubrication or even wear of guide rail. For the electrical control system, it may be that the speed ring. The position ring and relevant parameters are not in the best matching state. So the optimization adjustment should be carried out again after the mechanical failure is basically eliminated.

 

(5) Accidental shutdown failure. There are two possible scenarios:

 

  1. The problems in the design of related software result in the shutdown failure under some specific combination of operation and function. In general, when the machine tool is powered off and powered on again, it will disappear.

 

2. Caused by environmental conditions, such as strong interference, high temperature, humidity, etc. This kind of environmental factor is often ignored by people. For example, the machine tool is placed near the ordinary workshop or even near the open door in the southern region.

The electric cabinet is open for a long time, and there is a lot of equipment that produces dust, metal chips, or water mist nearby. These factors will not only cause failure but also damage the system and machine tool seriously. We must pay attention to improvement.

busbar cutting machine

Daily maintenance of the busbar cutting machine.

  1. The moving parts of the busbar cutting machine should be kept clean. And oil should be supplied several times a day to ensure the normal operation of each unit. Before starting the machine every day, check whether the oil level and the pipelines are abnormal. If there is any abnormality, please eliminate it in time and then work.
  2. The busbar cutting machine has not been used for a long time (more than two weeks). When it is started again, all moving parts should be cleaned and lubricated. After the machine is started, it needs to be idled for 5-10 minutes, and the machine can be operated after several times of normal operation.
  3. Check the level gauge in the oil tank regularly (every working day). When the oil is insufficient, please supplement it in time. The hydraulic oil must use the specified model (N46 in summer and N32 in winter).
  4. If the busbar cutting machine can not reach the service pressure after long-term use, please adjust the relief valve. When adjusting, loosen the lock nut and rotate the handwheel clockwise to boost the pressure, otherwise, it means to depressurize. Press the back button to the top dead center position and press continue to see if the pressure gauge pointer is about 25MPa (punching and shearing pressure is about 28Mpa, bending pressure is about 25MPa). When it can work normally, tighten the lock nut.

Some details

With the development of science and technology, different types of busbar processor have come out, of course, the fault phenomenon is also strange. A busbar processor is composed of many components. If one of the components fails, it will cause the abnormal phenomenon of the busbar machine. How many components does a busbar processing machine consist of? Maybe no one can count it.

Busbar processing machine failure, do not always complain busbar processor quality is not good, often bad. First of all, to check their own safety operation and maintenance procedures are correct. Keep the busbar processor clean, regular inspection and maintenance. Regular maintenance and maintenance can increase the service life of the busbar processor, avoid unnecessary trouble in the process of use.

In order to improve the service life of CNC equipment, it is generally required to avoid direct sunlight and other thermal radiation. And to avoid places with too much moisture, dust or corrosive gas. The corrosive gas is easy to cause the electronic components to be corroded and deteriorated.

Resulting in poor contact or short circuit between components, which affects the normal operation of the equipment. The precision numerical control equipment should be far away from the equipment with large vibration, such as punch, forging equipment, etc.

In order to avoid the influence of large power fluctuation (more than ± 10%) and possible instantaneous interference signal. CNC equipment generally adopts special line power supply (such as separate one way from low-voltage distribution room for CNC machine tool) or adding voltage stabilizing device. Which can reduce the influence of power supply quality and electrical interference?

The operation procedure.

The operation procedure is one of the important measures to ensure the safe operation of CNC machine tools. The operator must operate according to the operation rules. When the machine tool breaks down, the operator should pay attention to keep the scene and explain the situation before and after the fault to the maintenance personnel. So as to analyze and diagnose the cause of the fault and eliminate it in time.

In addition, CNC machine tools should not be stored for a long time. After purchasing CNC machine tools, they should be fully utilized, especially in the first year when they are put into use. So that the weak links that are prone to failure are exposed as soon as possible and can be eliminated within the warranty period. When there is no processing task, the CNC machine tool should also be powered on regularly.

It is better to power on 1-2 times a week and run for about 1 hour each time. So as to reduce the humidity in the machine by using the heat output of the machine itself, so that the electronic components will not be affected by moisture. And at the same time, it can timely detect whether there is a battery alarm, so as to prevent the loss of system software and parameters.

Also

The busbar processor has moving parts of punching, shearing, and bending units. A lubricating oil should be applied before the shift, each shift. Before off duty, the worktable and each unit are required to be oiled for maintenance. The punching die needs to be smeared with lubricating oil once every 50 times. The shearing mold needs to be smeared with lubricating oil once every 50 times. The bending mold needs to be smeared with lubricating oil once every 50 times.

Pay attention to whether the fixed bolts of each unit and the bolts at the bottom of the oil cylinder are tightened. Check the oil tank every 3 months to see whether the oil quantity is needed Oil injection. Hydraulic oil should be added when the liquid level is lower than or reaches the red line of oil standard. The characteristics of 46 anti-wear hydraulic oil will change every 6 months or after using for 5000-20000 hours. And tend to solidify (thicken). Generally, the oil should be changed when it is used for 5000 hours or the color of the oil turns brown and black.

In addition to environmental factors, the maintenance and maintenance of the busbar processor are also very important. Reasonable maintenance and maintenance is not only more smooth when using. But also can increase the service life of multi-functional busbar processing.

Improve the service life

In order to improve the service life of the busbar processor, the operating environment of the busbar processor requires avoiding direct sunlight and other thermal radiation. Avoiding places with too much moisture, dust or corrosive gas, and away from equipment with large vibration, such as punch, forging and pressing equipment, etc. in order to avoid the influence of large fluctuation of the power source and possible instantaneous interference signal.

Busbar processing machine generally adopts a special line Power supply. Or additional voltage stabilizing device can reduce the influence of power supply quality and electrical interference.

The busbar processor has not been used for a long time (more than two weeks). When it is started again, all moving parts should be cleaned and lubricated. After the machine is started, it needs to be idled for 5-10 minutes. After several times of operation, the machine can be operated again.

Some of the points

If the pressure can not be reached after long-term use, please adjust the relief valve. When adjusting, loosen the lock nut and turn the bolt clockwise to pressurize, otherwise, it means to depressurize. Press the back button to the top dead center position, press continuously. See that the pressure gauge pointer is about 25MPa (punching and shearing pressure is 28MPa, the bending pressure is adjusted to 16-20 MPa according to the back row). Can the test reach the normal working position and tighten the locking nut.

The moving parts of the busbar processor should be coated with lubricating oil before the shift, each time. Before work, the worktable and each unit are required to be oiled for maintenance. The punching, shearing, bending and other molds shall be coated with lubricating oil once every 50 times. And attention shall be paid to whether the fixed bolts of each unit and the bolts at the bottom of the oil cylinder are tightened. the oil tank shall be inspected regularly to observe the quantity of oil. when the liquid level is lower than or reaches the red line of the oil mark.

Hydraulic oil shall be added; generally, when the busbar processor is used for 5000 hours or more, the oil shall be applied When the color of the oil turns brown-black. The characteristics of the anti-wear hydraulic oil will change and tend to solidify (thicken). At this time, the hydraulic oil should be replaced in time.
