Description

Technical Field

[0001] This utility model relates to the field of metal profile processing technology, and in particular to a continuous roller die torsion forming device. Background Technology

[0002] In the existing technology, in the field of metal profile processing, especially in the production of products that require straight profiles to be processed into spiral products (such as threaded steel bars, spiral anchor rods, drill rods, torsion bar springs, etc.), it is usually necessary to straighten the profiles first and then twist them into shape. Traditional processing equipment often treats straightening and twisting as two relatively independent processes, or uses straightening mechanisms with few stages and insufficient precision.

[0003] The existing technology has the following problems: First, if the profile has an original bend before straightening or undergoes plastic deformation after unwinding, simple straightening is insufficient to completely eliminate these defects. This results in slightly bent profiles entering the torsion mechanism, where these initial straightness errors are amplified during torsion, causing uneven pitch, distorted spiral shape, and poor surface quality in the finished product, severely affecting product performance and quality consistency. Finally, non-straight profiles are prone to causing eccentric impact on the torsion die during torsion, accelerating die wear and increasing equipment maintenance costs and downtime.

[0004] Therefore, there is an urgent need for a torsion forming device that can achieve high-precision, continuous production, ensuring that the profiles have extremely high straightness before torsion, thereby guaranteeing the forming accuracy and overall performance of the final product.
