The double-drive roller frame automatically adjusts the roller swing angle according to the size of the workpiece during the operation. The double drive is stable and the driving ability is strong to a certain extent. The double-drive roller frame adopts frequency conversion stepless speed regulation and high precision. , manual control box forward, reverse, emergency stop, speed adjustment and other functions.
The transmission of the double-drive roller frame effectively drives the active roller, effectively utilizing the friction between the active roller and the cylindrical functional workpiece to drive the rotation of the workpiece to achieve displacement, and to a certain extent, the workpiece can be realized. The horizontal position welding of the inner and outer ring joints and the inner and outer longitudinal joints can be automatically welded by the automatic welding equipment, which can greatly improve the quality of the weld, reduce the labor intensity and improve the work efficiency.
The double-drive roller frame can also be used as a device for detecting and assembling cylindrical workpieces. The main feature of the roller frame is to apply pressure during the welding process without adding filler material. Most pressure welding methods such as diffusion welding and high There is no melting process in frequency welding, cold welding, etc., so there is no problem of burning of beneficial alloying elements like welding and intrusion of harmful elements into the weld. The welding of the roller frame simplifies the welding process and improves the safety and hygiene conditions of the welding.
