Description

Technical Field

[0001] The utility model relates to the technical field of workpiece straightening, in particular to a straightening mechanism for stainless steel bar processing. Background Art

[0002] Stainless steel rod is a common building material, widely used in construction, bridges, roads and other projects, but it needs to be straightened during the production and processing. The main purpose of straightening is to adjust the outer diameter, inner diameter and roundness of the stainless steel rod. Multiple straightening will refine the grain of the stainless steel rod, thereby improving its hardness, enabling it to withstand greater loads and pressures, and ensuring the stability and safety of the structure. The straightening devices on the market now use straightening rollers to straighten steel rods, but can only straighten steel rods of one specification. Different specifications require different devices, which makes the straightening process longer. For this reason, a straightening mechanism for stainless steel rod processing is proposed.
