Description

Technical Field

[0001] The utility model relates to the technical field of bolt thread rolling equipment, in particular to a thread rolling equipment for producing battery casing bolts. Background Art

[0002] Battery case bolts play multiple important roles in electric vehicles. They are key components to ensure the stability and safety of battery packs and the smooth operation of battery replacement processes. Bolt thread rolling equipment, also known as thread rolling machines, is a specialized screw production device. It is mainly used to form screw threads. Two thread rolling plates with the same thread shape and helix angle as the bolt threads move against each other to form threads on the bolt blank between the two rolling plates. Thread rolling machines are simple to operate and have high production efficiency. They are currently the most advanced and versatile thread forming machines.

[0003] Patent publication number CN208743591U discloses a screw thread rolling device, belonging to the field of new machinery in advanced manufacturing and automation. It includes a horizontal base and a vertical base perpendicular to the horizontal base. The horizontal base is equipped with a horizontally movable horizontal thread rolling plate, and the vertical base is equipped with a vertically movable vertical thread rolling plate. Both the horizontal and vertical thread rolling plates are driven by hydraulic cylinders.

[0004] Although the horizontal and vertical thread rolling plates of the screw thread rolling device can rely on the stable connection with the horizontal seat and the vertical seat to improve the stability during the thread rolling process, ensuring that the gap between the horizontal and vertical thread rolling plates remains unchanged during the thread rolling process, thereby enhancing the thread rolling effect of the screw of the utility model, the thread rolling surface of the horizontal thread rolling plate is parallel to the horizontal plane and faces upward. The debris generated during the thread rolling process will remain on the thread rolling surface of the horizontal thread rolling plate, which will affect the thread rolling effect during the thread rolling process, easily produce defective screws, and affect product quality.
