Production line for steel wire cut shots high in rigidity and long in service life

The utility model provides a production line for steel wire cut shots high in rigidity and long in service life. The production line is used for producing the steel wire cut shots high in rigidity, and comprises a pay-off rack, a single-wire film coating groove, a dryer, a first wire drawing machine, a cleaning box, an annealing furnace, a cooling pond, a first wire take-up machine, a water tank, a second wire drawing machine, a second wire take-up machine, a shot cutting machine, a rounding passivating machine and a vibrating screen, wherein the pay-off rack, the single-wire film coating groove, the dryer, the first wire drawing machine, the cleaning box, the annealing furnace, the cooling pond, the first wire take-up machine, the water tank, the second wire drawing machine, the second wire take-up machine, the shot cutting machine, the rounding passivating machine and the vibrating screen are sequentially connected from front to back. A steel wire to be cut into the shots sequentially penetrates through the single-wire film coating groove, the dryer, the first wire drawing machine, the cleaning box, the annealing furnace, the cooling pond, the first wire take-up machine, the water tank, the second wire drawing machine and the second wire take-up machine to be fed to the shot cutting machine. The steel wire cut shots produced by the production line are high in rigidity which can reach 58-60HRC, low in breakage rate, long in Owen service life which can reach more than 4000 times, high in processing speed and capable of meeting the requirements of the domestic shot blasting industry.
