Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing and straightening equipment, and more specifically, to a raw material straightening structure before automatic bolt forming. Background Art

[0002] The manufacturing process of bolts includes annealing, pickling, wire drawing, forming and other steps. Its quality and production efficiency are crucial to overall product quality and cost control. In order to improve the forming quality of bolts and reduce the defective rate caused by bending and twisting of raw materials, it is necessary to straighten the raw materials of bolts efficiently and accurately to provide high-quality raw materials for subsequent forming processes.

[0003] In actual industrial production, the round steel bars used as bolt raw materials are curled into bundles, which causes the steel bars to bend in multiple places. It is difficult to straighten all the bends, resulting in low work efficiency and poor straightening effect.

[0004] After searching, a Chinese patent with publication number CN212760831U discloses a bolt raw material straightening device. In order to facilitate bolt processing and make the round steel bars straight, the positions of multiple straightening wheels and the positions of the first straightening roller assembly and the second straightening roller assembly are adjusted so that the round steel bars enter from the straightening notch, the bending degree of the steel bars becomes smaller, and through the triple straightening operation, the bent state of the steel bars is changed to a straight state, which is conducive to subsequent processing. The installation is simple and the operation is convenient and quick.

[0005] However, when this structure is actually used, the steel bar is inserted from the straightening notch and then straightened through a triple straightening operation. However, since the triple straightening operations are performed on both sides of the bolt material and the straightening wheel can only be adjusted front and back, it is difficult to adjust the height of the straightening wheel, which results in it being only applicable to bolt materials of fixed sizes, with low flexibility and practicality, and poor use effect.
