Walking pipe rotator

Product Introduction For walking pipe rotator:

The walking pipe rotator are a kind of auxiliary welding equipment, usually used for welding the inner and outer circular seams and the inner and outer longitudinal seams of cylindrical workpieces. The walking pipe rotator adopts a screw to move the rotator in steps, and adjust the center distance of the rotator to adapt to the change of the workpiece diameter. The walking pipe rotator include a base, an active rotator, a driven rotator, a bracket, a transmission device, and a power device drive.

The frequency converter adopts step-less speed regulation, wide adjustment range, high precision, and large starting torque; the manual control box is simple and reliable to operate, has a variety of self-protection functions, and can leave a linkage interface in the electrical box, which can be connected with the welding manipulator, etc. The control system of the welding equipment is connected to realize linked centralized control. Greatly improve the quality of welds, reduce labor intensity, and improve work efficiency. The walking pipe rotator can also be matched with manual welding or as a device for detecting and assembling cylindrical workpieces.

What are the maintenance procedures for the walking pipe rotator

1. Check and remove the obstacles on the machine before welding and use and keep it by special personnel. Do not touch the oil and fire when the automatic walking welding rotators is connected and frequently fill the oil holes.
2. Rolling bearings: Lubricate through the oil cap on the bearing cover. Sodium-based grease is recommended.
3. Transmission gear: For the first use, you need to remove the gear shield that is added actively, and apply a proper amount of grease. Sodium-based grease is recommended. During use, lubricating grease can be filled through the oil filling hole on the gear cover, and foreign matter is strictly prohibited from falling into the gear.
4. Cycloidal pinwheel reducer: Please add grease as required before use. Grease-2#, molybdenum disulfide-2#, or 2L-23 lithium-based grease is recommended at room temperature. The amount of grease loaded is 1/2-1/3 of the volume of the reducer. It is not advisable to add too much grease; otherwise, it will generate heat of stirring. The reducer should be replaced for the first time after 300 disappeared during the first operation. When replacing, the remaining dirty oil should be removed. Replace it every 6 months after that.
5. To ensure the equipment's performance, all transmission parts should be checked for lubrication regularly and irregularly. The cycloid reducer must be checked monthly to make up for lubricating oil.
6. All transmission parts are not lubricated and are strictly prohibited from using.
7. Before restarting the equipment that has been sealed for a long time, the grease must be replaced.
8. During use, the roller should fully contact the workpiece. It is strictly forbidden for the welding seam or sharp parts to touch the roller to avoid damage to the roller.
9. When hoisting and placing the workpiece, it is strictly forbidden to vigorously hit the roller to prevent damage to the rotator or other parts. When the device is not fixed, a strong impact may cause the device to overturn.
10. When the automatic walking welding rotators are used for a small diameter cylinder, if the cylinder moves axially, adjust the adjusting bolt under the arc plate to adjust the roller lifting position (within a certain range) to ensure the cylinder The working position is in the best condition.

How to clean the exterior of the walking pipe rotator?

Stainless steel pressure vessel as a special vessel. Its manufacturing should have an independent and dedicated site and should be strictly isolated from carbon steel products. If the stainless steel pressure vessel is attached to carbon steel parts, the manufacturing site of the carbon steel parts shall be separated from the stainless steel. To prevent the pollution of iron ions and other harmful impurities, the production site of stainless steel pressure vessels must be kept clean and dry, and the ground should be covered with rubber or wood floors. The stacking of semi-finished parts and finished products must be equipped with wooden stacking racks. During the manufacturing process, sharp and hard materials should be avoided to scratch the surface of stainless steel. If there are local bumps or scratches on the surface of the stainless steel pressure vessel that affect the corrosion performance, it must be repaired.
To ensure the quality of stainless steel products, ensure the performance of the equipment, and extend the service life. The outer surface of the roller rack must be cleaned before use. All drives should be regularly checked for lubrication. In the process of lubrication and use, avoid foreign matter from falling into it. Turn on the switch to start the motor for a trial run, and observe whether all parts are running normally. Work can only be carried out after confirming that there is no problem. The height and longitudinal position of the walking pipe rotator of the main and follower are required to be installed during installation. If it is not placed properly, the weldment will be displaced during rotation. Always pay attention to the hygiene around the equipment. Make the equipment work normally in a clean and clean environment.

What should I pay attention to when installing the walking pipe rotator?

1. The walking pipe rotator should be installed in a place that is sturdy, ventilated, rainproof, moisture-proof, dust-proof, and away from severe vibration and bumps. It is strictly forbidden to spray corrosive liquids on the equipment.
2. It is strictly forbidden to spray the corrosive liquid on the equipment. When the main and driven walking pipe rotator are installed simultaneously, make sure that the main and driven frames are at the same height, the center and center lines are on the same straight line, and adjust the diagonal of the main and driven frames.
3. Requirements for placing the workpiece: the diameter and weight of the workpiece should be strictly implemented by the design regulations; otherwise safety and total accidents are easy to occur, and the distance between the main and auxiliary wheels should be adjusted according to the length of the equipment.
4. When in use, the rotator should fully contact the workpiece, and welding seams or sharp parts are strictly prohibited. At the same time, when lifting the workpiece, it is strictly forbidden to hit the rotator to prevent the rotator or other components from being damaged. If the equipment is not fixed, a strong impact may cause the whole machine to overturn.

What is the operating procedure for walking pipe rotator?

1. Check whether all parts of the lathe are in good condition before work and start working after confirmation.
2. It is forbidden to disassemble, install or inspect equipment and remove welding impurities while the roller frame is in operation.
3. When inspecting the motor, you must check all the bearings and use a dry cloth and manual blower to remove the coil's dust. The ball bearings should be inspected twice a year and replaced with new grease or other appropriate lubricating oil. Damaged, replace it immediately.
4. The connection of the motor wire must be checked every ten days. The contact piece must be very tight to avoid overheating or oxidation at the contact point. The grounding screw must also be checked on time.
5. All parts of electrical equipment must be kept clean. After the contact piece is worn out, it should be replaced immediately. The contractor cannot be lubricated because lubricating oil is not good for it.
6. If the machine has abnormal phenomena during use, it should be shut down immediately for inspection to prevent malfunctioning equipment.
7. It is strictly forbidden to maintain, overhaul, and maintain the equipment during operation.
8. Use the machine to clean the site and remove the debris on the fuselage.
9. Overload use is strictly prohibited.
