Adjustable pipe rotators for welding

Product Introduction For Adjustable pipe rotators for welding:

The adjustable pipe rotators are composed of a driving wheel and a driven wheel. The active roller is driven and operated by two motors separately. Through the speed regulating motor, the speed controller realizes the step-less speed change through frequency conversion speed regulation or electromagnetic speed regulation. The linear speed of the workpiece rotation is 6-60 meters per hour, which can meet the needs of various welding such as manual welding, automatic surfacing welding, automatic submerged arc welding, and various riveting of the workpiece.

The pitch of the master and slave rollers can be adjusted through the screw or screw to meet the welding requirements of workpieces of different specifications. The adjustable pipe rotators can be used in conjunction with the welding manipulator, and it can weld the inner and outer longitudinal seams and the inner and outer ring seams of the cone and the unequal-diameter slewing workpiece.

Maintenance procedures for adjustable pipe rotators

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 adjustable tank welding turning rolls are 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 adjustable tank welding turning rolls 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 rolls or other parts. When the device is not fixed, a strong impact may cause the device to overturn.
10. When the adjustable tank welding turning rolls is 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 adjustable pipe rotators?

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 adjustable pipe rotators 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 adjustable pipe rotators of the main and follower are required to be installed during installation.
