Various forms of lead screw welding rotator and welding process

- Jul 04, 2019-

The lead screw welding rotator can be divided into self-adjusting type and adjustable type when it is used, and is suitable for welding, polishing, lining, assembling and the like of the cylinder body. The screw roller frame can be adjusted according to the size and self-weight of the cylinder. The adjustable roller frame can manually adjust the center distance of the roller, etc. The regenerative control adopts AC frequency conversion speed regulation to improve the running reliability. The company can also design and customize other types of roller frames according to user needs.


The screw roller frame automatically adjusts the roller swing angle according to the size of the workpiece. The double drive is stable, the driving ability is strong, the frequency conversion stepless speed regulation is adopted, the precision is high, the manual control box rotates, reverses, stops urgently, speed adjustment and other functions, and can be equipped with feet. Step switch.


The screw roller frame is a welding auxiliary device, in particular, a welding roller frame, which is commonly used for welding inner and outer circumferential seams of cylindrical workpieces and internal and external longitudinal joints. Including the base, the active roller, the driven roller, the bracket, the transmission, the power unit drive and the like. The transmission drives the active roller, and the friction between the active roller and the cylindrical workpiece drives the workpiece to realize the displacement. The inner and outer annular seams of the workpiece and the horizontal position welding of the inner and outer longitudinal joints can be realized. The automatic welding equipment can realize automatic welding. It can greatly improve the quality of welds, reduce labor intensity and improve work efficiency.


The screw roller frame can also be used with manual welding or as a device for detecting and assembling cylindrical workpieces. It is the application of pressure during the welding process without adding filler material. Most pressure welding methods, such as diffusion welding, high-frequency welding, cold-welding, etc., do not have a melting process, so there is no problem of burning of beneficial alloying elements like welding, and the intrusion of harmful elements into the weld. The welding of the roller frame simplifies the welding. The process also improves the safety and hygiene of the weld. At the same time, since the heating temperature is lower than the fusion welding and the heating time is short, the heat affected zone is small. Many materials that are difficult to weld by fusion welding can often be welded to a high-quality joint of the same strength as the base metal.
