This utility model relates to a fine drawing machine, and more particularly to a copper wire fine drawing machine with a wire breakage alarm function. It provides a copper wire fine drawing machine with clamping protection and a wire breakage alarm function. It includes a machine base, a pay-off roller, a take-up roller, a water collection tank, a drawing roller, a winding wheel, a liquid collection tank, and a tensioning assembly. Tensioning assemblies are respectively installed on the top of the machine base near the take-up roller and the pay-off roller for adaptive tensioning of the copper wire. The tensioning assembly integrates an alarm and a pressure sensor. Through the coordinated operation of the pay-off roller, the take-up roller, the tensioning assembly, and the drawing die sleeve, continuous thinning of the copper wire can be achieved. A linear motor drives the tensioning wheel assembly to reciprocate, and the pressure sensor monitors the tension force in real time. An alarm sounds for wire breakage, and when a wire breakage occurs, a cylinder is automatically triggered to drive the clamping bar to instantly move downwards to clamp the copper wire, preventing it from slipping off. This effectively reduces the number of threading operations and improves production efficiency and safety.
