Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a treatment device for improving the thermal properties of the sawn end of a round bar. Background Technology

[0002] The treatment device for improving the thermal properties of the sawn ends of round bars precisely controls the cooling rate of the ends through spraying, misting, or air cooling, avoiding cracking, coarsening of the microstructure, or concentration of residual stress caused by rapid cooling, while preventing grain coarsening caused by slow cooling, thereby improving the mechanical properties of the material and the processing quality.

[0003] During the sawing of round bars, surface cooling is necessary to prevent end coarsening or deformation caused by high temperatures. However, existing technologies often rely on unidirectional spraying or open-air cooling, resulting in uneven cooling medium coverage on the end face. The edge areas near the nozzles or air vents cool and contract rapidly due to the strong impact and high heat exchange efficiency of the medium, while the central areas, farther from the heat source, experience significantly slower cooling due to medium diffusion attenuation and a longer heat dissipation path. This spatial cooling difference leads to severely asynchronous thermal expansion and contraction processes on the end surface, creating an uneven stress field within the material. This creates a breeding ground for microcracks and dimensional deformation, ultimately affecting machining accuracy and end face quality. Utility Model Content

[0029] The driving component 42 is configured in two sets, which are arranged opposite to each other, and the two first sun gears 421 are fixedly connected to the two ends of the hollow cylinder 41 respectively.

[0030] Output component 43 includes a tube 431 fixedly connected between two first planetary gears 422. Multiple flow grooves 432 are opened on the outside of the tube 431.
