Description

TECHNICAL FIELD

[0001] The utility model relates to rough diameter steel material processing technical field especially, relates to a sleeve rough diameter steel material straightening mechanism. BACKGROUND

[0002] The sleeve rough diameter steel material straightening mechanism is used for correcting the bending or distortion of the rough diameter steel material during production and processing. The mechanism usually consists of straightening rollers, a driving system, a clamping device, and a control system. The straightening rollers are arranged in a specific pattern to apply uniform straightening force to the steel material. When the rough diameter steel material passes through the straightening mechanism, the driving system rotates the rollers, and the clamping device fixes the position of the steel material to allow it to be subjected to appropriate pressure and bending as it passes through the rollers, gradually eliminating internal stress and restoring its straightness. The control system adjusts the straightening force and speed to ensure that the straightening process is effective and does not cause excessive damage to the steel material, meeting the requirements of subsequent processing for material straightness.

[0003] The traditional sleeve rough diameter steel material straightening mechanism has certain safety risks when performing the discharging operation. Specifically, when the steel material passes through the straightening process and is completely discharged from the straightening mechanism, the front end of the steel material will inevitably bend downward due to gravity, causing the front end to fall. At the same time, the rear end of the steel material will easily produce an upward rebound force due to the release of elastic potential energy during the straightening process, causing the rear end to lift. This phenomenon can easily cause the steel material to deviate from the preset track during the discharging process, leading to safety accidents and posing a potential threat to operators and production equipment. Therefore, it is necessary to improve the existing straightening mechanism to solve this instability problem during discharging. SUMMARY

This phenomenon can easily cause the steel material to deviate from the preset track during the discharging process, leading to safety accidents and posing a potential threat to operators and production equipment.
