Conductor and self-protection function of the roller frame

- Mar 06, 2019-

In the process of operation, the roller frame can automatically adjust the swing of the wheel set according to the diameter of the workpiece, and can automatically adjust the heart. When the product and the welding machine are used together, the welding machine can be used. The inner and outer longitudinal seams of the workpiece are welded together with the inner and outer circumferential seams.

The roller frame has low transmission noise and stable workpiece rotation, so that the cylindrical cylinder can be welded, rubberized, assembled, polished, etc., and the roller speed should be uniform and stable during use, and not used when in use. Allowing for crawling.

The roller frame must have over-voltage protection and self-protection functions to a certain extent. Its products will have its fault display and storage functions, automatic air switch short-circuit protection, and preset parameters. Appropriate adjustment of the height of the main and driven rollers can also be carried out for the assembly and welding of cones and segmented unequal-diameter rotors.

The roller frame adopts its digital adjustment and display technology in the process of rotating speed. The setting of welding speed is very intuitive, accurate and reduces the operation difficulty of the workers. The manufacturing and assembly precision of the products should meet the international precision requirements effectively. 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.

To a certain extent, 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 during use. When the cylinder type workpiece is welded on the anti-axial rolling roller frame, the axial movement amount of the workpiece during the whole welding process should be ≤ ± 3 mm.

The center distance of each pair of rollers of the roller frame must be able to effectively adjust according to the diameter of the workpiece of the cylinder type, so that the angle of the two rollers to the simplified package can be effectively ensured by 45° and less than 110°. . With 15m control cable, roller positive and negative switch, near control, remote control switch.

When the roller of the roller frame is made, it is best to use its rubber material. During operation, it is mainly free to swing by the pair of rollers. The center distance of the roller is automatically adjusted within the specified amount. It is suitable for different use. The diameter of the weldment, the round weldment is placed
