Abstract

This invention relates to the field of aluminum alloy billet processing equipment. It discloses a device for precise control of aluminum alloy billet rolling thickness, including a frame assembly, a roll assembly, a clamping assembly, and a thickness detection assembly. The clamping assembly consists of a sliding assembly, a width adjustment assembly, and a gripping assembly. The sliding assembly allows for vertical height adjustment to accommodate billets of different thicknesses; the width adjustment assembly flexibly adjusts the lateral spacing to accommodate billets of varying widths and ensures centered feeding; the gripping assembly employs a pneumatic linkage structure to achieve stable and controllable clamping, preventing billet damage and slippage. A non-contact laser thickness measurement module on the exit side collects data in real time and feeds it back to the roll gap adjustment mechanism, forming a closed-loop control for real-time fine-tuning of the roll gap. This invention significantly improves the uniformity and accuracy of rolling thickness through multi-dimensional precise control, adapting to high-precision rolling production of multi-pass, multi-specification aluminum alloy billets, and possesses good versatility and practical value.
