OEM high quality Customized OEM bronze valve

Every enterprise or individual engaged in welding hopes to give full play to the performance of the equipment and prolong the service life of the machine. To achieve this goal, in addition to the correct use of welding equipment in accordance with the operating procedures, maintenance and repair work should also be done regularly. OEM high quality Customized OEM bronze valve

The maintenance points of the welding torch, wire feeding device, welding machine and welding robot will be explained one by one.

1. Maintenance of welding torch
2. Regularly check and replace the contact tip

As the aperture of the worn contact tip becomes larger, the arc will be unstable, the appearance of the weld will deteriorate, or the wire will stick (burn back); the end of the contact tip sticks to splashes, and the wire feeding will become uneven; the contact tip is not tightened tightly, The threaded connection will heat up and die.

2. Regularly clean and replace the spring hose

After the spring hose is used for a long time, a large amount of iron powder, dust, welding wire plating scraps, etc. will accumulate, which will make the wire feeding unstable. So regular cleaning is important, you can curl it and tap it lightly to shake off the buildup, then blow it off with compressed air. The grease on the hose should be scrubbed in the oil with a brush, and then blown off with compressed air. If the spring hose is wrongly wired or seriously deformed and bent, a new hose should be replaced. When changing the tube, make sure that it is suitable for the diameter and length of the welding wire used, and that there is no burr on the cut surface. OEM high quality Customized OEM bronze valve

3. Inspection of insulating ferrules

If the insulating ferrule is removed for welding, the spatter will adhere to the inside of the nozzle and conduct the nozzle to the live part. The torch may burn out due to a short circuit. At the same time, in order to make the protective gas flow out evenly, an insulating ferrule must be installed.

2. Maintenance of wire feeding device
3. Pressure adjustment

The feed roller pressure should be adjusted appropriately according to the wire diameter used. If the pressure is insufficient, the wire will slip; if the pressure is too high, the wire will be scratched and deformed. If flux-cored wire is used, the pressure of the feed roller is smaller than that of solid-cored wire.

2. Adjustment of wire straightening device

The adjustment method of the welding wire straightening device varies with different models, and should be adjusted to the appropriate position of the corresponding welding wire diameter according to the manufacturer’s mark. OEM high quality Customized OEM bronze valve

3. Installation of the wire reel

If the installation is not in place, the wire spool will be in danger of falling off during rotation, resulting in serious consequences. Carefully check that the brake pads or latches are securely installed.

4. Wire feed roller and wire diameter used

A wire feed roll suitable for the diameter of the wire used must be fitted, and check that the number engraved on the roll is consistent with the diameter of the wire used.

5. Wear and contamination of the groove of the wire feed roller

Check whether the groove of the wire feed roller is worn, whether the surface of the groove is scratched, and whether there is dust, iron powder, welding wire plating, etc. adhered to the groove. When cleaning, use a cotton gauze rag to wipe clean. OEM high quality Customized OEM bronze valve

6. Inspection of the guide wire nozzle

If the wire guides installed before and after the wire feed roller are worn or not level with the wire feed roller, the welding wire will be bent and the wire feeding will be unstable. Therefore, regular inspection and maintenance are required.

3. Maintenance of the welding machine

First of all, special attention should be paid to the fact that the inspection of the internal or external joint terminals of the welding machine must be performed after the input power switch is turned off.

1. Do a good job of testing on a regular basis. For example, check whether the cooling fan rotates smoothly when the welding machine is powered on; whether there is abnormal vibration, sound and odor; whether there is leakage of gas; whether the joints and insulation of the welding wire are loose or peeled; Check whether there is abnormal heating in the wiring part.
2. Since the welding machine is cooled by forced air, it is easy to inhale dust from the surroundings and accumulate in the machine. Therefore, we can regularly use clean and dry compressed air to blow away the dust inside the welding machine. In particular, the transformers, reactance coils, gaps between coils, and power semiconductors should be cleaned.
3. Regularly check the wiring parts of the power wiring. Check whether the terminals on the input side and output side, as well as the wiring parts of the external wiring and the wiring parts of the internal wiring are loose. OEM high quality Customized OEM bronze valve
4. The long-term use of the welding machine will inevitably cause the shell to be deformed due to contact, rusted and damaged, and the internal parts will also be worn away. Therefore, during the annual maintenance and inspection, it is necessary to replace the defective parts, repair the shell and deteriorate the insulation. Comprehensive repair work such as reinforcement of parts. Replacement of defective parts It is best to replace all new parts at one time during maintenance to ensure the performance of the welding machine. The regular maintenance and inspection implemented above can reduce the occurrence of welding failures. Although it takes some time and effort, it can prolong the life of the welding machine, improve the efficiency of the operation, ensure the performance of the welding machine and improve the safety. It is an important content that cannot be ignored in welding work.

Fourth, welding robot operation and maintenance

1. Robot operators must undergo professional training, understand the use of system indicators and buttons, and be familiar with the most basic equipment knowledge, safety knowledge and precautions before use.
2. Inspection work before the robot works

The trunking, the wires are not damaged and exposed;

It is strictly forbidden to place sundries, tools, etc. on the robot body, external shaft, gun cleaning station, and water cooler; 3. It is strictly forbidden to place liquid objects (such as water bottles) on the control cabinet; OEM high quality Customized OEM bronze valve

The operating room is free of flammable items (such as cotton shoes);

The temperature of the operating room shall not exceed 25 degrees Celsius;

No air leakage, water leakage and electricity leakage;

The welding tool thread is not damaged, and the robot is not abnormal;

There is no magnetic field or vibration source (such as a magnet) in the working range of the robot

3. Power on

Open the main switch;

Turn on the power supply of the control cabinet, welding machine and water cooler (note that KUKA first open the control cabinet and then turn on the welding machine);

After the robot is powered on, there is no alarm before it can operate.

4. When using the teaching box to operate the robot and run operations, please make sure that there are no stray people within the robot’s motion range. Non-workers or maintenance personnel are not allowed to enter the operating room.
5. After the teaching box is used, it should be placed in the specified position, away from the high temperature area, and cannot be placed in the working area of ​​the robot to prevent collisions and damage to personnel and equipment.
6. Operation and maintenance

Install the fuel tank as required and install the flange cover; OEM high quality Customized OEM bronze valve

Press the green run key; (when the debugger adjusts the program)

After welding, loosen the pressure block first and then lift the fuel tank;

After welding a fuel tank, check whether there are uncleaned spatter burrs in the nozzle and whether the welding wire is bent; manually clean the inside of the nozzle for every four fuel tanks welded (about 2 large fuel tanks are welded, and each one should be cleaned and cleaned if it is not normal). Please follow the training taught)

Keep the fuel injector of the gun cleaning station unblocked and there is oil in the oil bottle;

Keep the cooling fins of the water cooler clean and the water level not lower than the warning line;

The robot body is cleaned once a week;

The gun cleaning station is cleaned once a day;

The gripper should be replaced with adhesive tape every two weeks;

If there is an abnormality during the operation, contact the debugger immediately;

When the robot is working, there is a fault alarm, air holes appear, the fuel tank is welded, the gun is hit, and the gun is clamped. It is not allowed to adjust the program without permission.

7. Keep the safety marks of the robot clean and clear. If damaged, it should be replaced in time.
8. When the work is over, turn off the power supply, close the gas valve, pull the main switch, clean up the equipment, and organize the site. OEM high quality Customized OEM bronze valve
