What is the reason that there are sparks and smells in the operation of the steel bar straightening

Sparks, be careful of short circuits, smelly because sparks hit out of the ozone possible.

Switched to non-original carbon brushes; The carbon brush is hard or the grade does not meet the requirements; Solution: Replace the original carbon brushes. 2. The spring pressure on the carbon brush of the motor is uneven; Workaround:

Adjust the spring pressure appropriately so that the pressure of each carbon brush is equalized. 3. The brush grip is loose; Solution: Tighten the brush grip bolt so that the brush grip is parallel to the surface of the commutator.

4. The distance between the brush grip and the surface of the commutator is too large; Solution: Adjust the distance from the brush grip to the commutator, generally 1 3mm. 5. Poor contact between the carbon brush and the commutator; Workaround:

The carbon brushes may be worn out too shortly, grinding the carbon brush contact surface or replacing the carbon brushes with new ones. 6. Improper coordination between the carbon brush and the brush grip; Solution: not too tight or too loose, to ensure that the brush can slide freely in the brush grip when it is hot, too tight can use sandpaper to sand the carbon brush appropriately, too loose to replace the new carbon brush.

7. The mica between the pieces of the commutator is not cleaned, and the remaining mica is removed with a hand broacher; Solution: The mica protrusion between the commutator sheets. Finish turning commutator.

8. The center position of the brush holder is wrong; Solution: Move the brush holder and select the best location for the spark. 9. Short circuit of reversing pole coil; Workaround:

Rewind the coil. 10. Armature winding short circuit; Solution: Disassemble the motor, check the armature winding, use a millivoltmeter to find the open circuit, if it cannot be welded, it will be rewound.

If the conditions are not met, replace the armature with a new one. 11. If none of the above problems are true, it may be caused by the following factors: (1) The bearing is worn and the starting current is large.

2) The contact area between the carbon brush and the rotor is small. (3) The carbon brush pressure is small and there is no full contact with the rotor.

1.Check whether the oil pipeline is assembled correctly, and assemble it according to the manual;

2.Check whether the lower cutter is too small or too aggressive, generally speaking, the gap of the lower cutter should be kept at about millimeters;

3.Check whether the solenoid reversing valve is not reversing, and check the line connection and electrical conditions, if the solenoid reversing valve is faulty, it should be replaced.

4.Check the high pressure for shut-off, if there is any abnormality in the shut-off high pressure, the pressure should be adjusted according to the instructions;

5.Check whether the gap between the upper and lower knives is too large, if there is any difference, it should be adjusted to about millimeters;

6.Check whether the delay disconnection time and relay time are adjusted shortly, and if any difference is found, it should be set to seconds;

7.Check whether the strength of the steel bar to be cut is too high, the user can use the previously cut steel bar to recut it on the machine once, so as to distinguish the strength of the steel bar to be cut is greater than 750N.

The more detailed the situation, the better it is to find the problem, the mechanical cutting principle of hydraulic pressure is not the same, it is not cut or cut constantly, I can't help you, and the specific can be consulted.

Sometimes it is cut, sometimes it is not, and it is just a slight movement.

There are several possible causes:

1 Mechanical design flaws.

2. The hardness of the wire is large, the motor power is not enough or the cutter head is not sharp enough, and the cutter head cannot operate normally.

4 There is a problem with the operation or installation.

5 Electricity** may be in poor contact, or should use high voltage electricity only low voltage electricity resulting in insufficient power.

6. Those that are too thick are generally cut off by hydraulics, such as 13-14mm or thicker ones are generally cut off by hydraulics.

For many reasons, the specific ** consultation - Dongsheng straightening machine professional factory.

Guangdong Hongtian straightening machine, please pay attention to the purchase.

Some machines are CNC to set the length, some are to use the air gauge to set the length, CNC to set the length, the cutter value to zero, cut a few more. If you want to set the length of the air gauge, you can adjust the air gauge.

The automatic rebar straightening and cutting machine is used to straighten and cut steel bars with a diameter of less than 14 mm, and to remove rust. It is composed of a straightening cylinder, a pulling mechanism, a cutting mechanism, a steel bar fixed length frame, a frame and a driving device.

Look at what kind of machine it is, some machines are CNC to set the length, some are to use the air gauge to set the length, if the CNC sets the length, the cutter value is zeroed, and a few more are cut. If you want to set the length of the air gauge, you can adjust the air gauge.

How to set the size error of the straightening machine.

Mechanical, hydraulic, send a set to my QQ mailbox, thank you!

I want it too, and if I have one, please ask a friend to give me one.
