10 technical requirements for welding roller frame Sep 30, 2018

1. The welding roller frame will automatically adjust the swing angle of the wheel set according to the diameter of the workpiece, and can automatically adjust the center. When matched with the welding machine and welding power source, the inner and outer longitudinal joints of the workpiece and the inner and outer ring seam welding can be realized.

2. The transmission noise of the welding roller frame is low, and the workpiece of the whole equipment rotates smoothly, so that the welding, polishing, rubber lining and assembly operations of the cylindrical cylinder can be effectively realized to a certain extent, and the rotation speed of the roller should be stable and uniform. . No crawling is allowed.

3. To have over-voltage protection, its self-protection function, fault display and storage function, automatic air switch short circuit protection, preset parameters.

4. Appropriate adjustment of the height of the main and driven rollers, as well as the assembly and welding of cones and segmented unequal-diameter rotors.

5. For some non-circular long weldments, they are stuck in a special ring clamp, and can also be welded on the welding roller frame.

6. Self-adjusting roller frame adopts digital adjustment and display technology for the rotation speed of the roller. The setting of welding speed is very intuitive and accurate, which reduces the difficulty of operation of workers.

7. The manufacturing and assembly accuracy of the roller frame should meet the accuracy requirements of the 8th grade in the national standard. The roller frame should be made of high quality steel. If the base of the welded structure is used, stress relief heat treatment must be performed after welding.

8. The roller carriage must be equipped with a reliable conductive device that does not allow welding current to flow through the bearings of the roller carriage.

9. The center distance of each pair of rollers of the roller frame must be adjusted according to the diameter of the cylinder-like workpieces to ensure that the wrap angle of the two rollers is 45° larger than 110°.

10. With 15m control cable, roller forward and reverse switch, near control, remote control switch.
