AI Technical Summary
Existing coil spring forming machines face issues with responsiveness of high-frequency heating for cutting, adverse effects on cutting tools, and challenges in maintaining consistent forming accuracy due to partial heating of wires. Additionally, laser-based cutting systems face problems with spatter and uneven application of laser light.
A coiling machine that uses laser heating to create a heated portion of the wire, which is then cut using a cutter, resulting in a quench-hardened zone and a heat-affected zone. This process allows for precise cutting and improved spring quality.
The solution enables easy cutting of helically shaped wires, reduces wear on cutting tools, and enhances the quality and consistency of coil springs by ensuring precise cutting and reduced residual stress.
