This invention discloses a method for forming ultra-large titanium alloy U-shaped profiles, comprising: 1. Initial heating of titanium alloy sheet using a tracked heating device; 2. Rapid transfer and first bending of the titanium alloy sheet under heat preservation conditions; 3. Second heating and bending of the L-shaped single-sided bent part; 4. Milling the edges of the U-shaped double-sided bent part; 5. Performing steel plate pressing and shaping heat treatment on the milled U-shaped double-sided bent part; 6. Performing surface treatment on the heat-treated U-shaped double-sided bent part to remove surface oxide scale, thereby obtaining the finished titanium alloy U-shaped profile. This invention optimizes the layout of the tracked heating device and bending machine, constructing an L-shaped rapid transfer path, thus solving the cracking problem caused by temperature drop in ultra-large titanium alloy sheet and ensuring the temperature stability of the titanium alloy sheet during bending; the large bogie furnace steel plate pressing and shaping heat treatment process improves the uniformity of the U-shaped double-sided bent part's shaping.

This utility model discloses a stress relief device for laser welding of circular saw blades, relating to the field of circular saw blade manufacturing technology. The utility model includes a base, a conveying assembly on top of the base, a supporting assembly on top of the conveying assembly, an adjusting assembly inside the supporting assembly, a displacement assembly on one side of the conveying assembly, and a stress-relieving assembly on the other side. The conveying assembly is used to move the supporting assembly and the circular saw blade, and the supporting assembly is used to hold the circular saw blade. Through the connection of the supporting assembly and the adjusting assembly, after the circular saw blade is placed on the outer surface of the supporting assembly, moving the adjusting assembly inside the supporting assembly simultaneously moves two sets of supporting members of the supporting assembly. The two sets of supporting members can move away from or closer to each other, thereby enabling the supporting assembly to support and fix circular saw blades of different apertures. No replacement of the supporting assembly is required during use, making it convenient.
