AI Technical Summary

Technical Problem

Medium and large track rollers face challenges in workpiece positioning and clamping stability during welding. Furthermore, magnets are prone to magnetic attenuation or permanent demagnetization at high temperatures, leading to fixture detachment and impacting safety and service life.

Method used

Design a friction welding device for medium and large support rollers. Employ symmetrically arranged semi-circular clamping components and utilize centrifugal force to disengage the magnetic moving parts from the wheel axle. Combined with heat-insulating semi-rings and ventilation slots, reduce the temperature rise of the magnetic sheet, prevent magnetic attenuation, and ensure stable positioning of the clamp at high temperatures.

Benefits of technology

It achieves stable positioning of magnetic components in high-temperature environments, avoids magnetic attenuation, ensures the safety of the welding process and the reliability of the fixture, prevents the fixture from loosening, and extends service life.
