The invention discloses a long-service-life spiral wire guide transmission box of a thread rolling machine. The spiral wire guide transmission box comprises a transmission box body, wherein a bottom protective shell is arranged at the bottom of the transmission box body, and a first bolt is arranged at the bottom of the bottom protective shell; and protection pads are symmetrically arranged on thefront side and the rear side of the transmission box body, each protection pad is internally provided with a plastic foam layer, an aluminum alloy plate layer and a stainless steel plate layer from back to front in sequence, and a second placing groove is formed in the left end of the top of the transmission box body. According to the long-service-life spiral wire guide transmission box of the thread rolling machine, through the arrangement of a roller bearing, a waterproof protective cover, a protective plate, the stainless steel plate layer, a chloroprene rubber layer, an asphalt felt layer, the protective pads, the plastic foam layer, the aluminum alloy plate layer and the stainless steel plate layer, the problem that the productivity is affected by frequent faults of the transmissionbox due to the fact that the strength of a bearing used in an original design of third transmission of a spiral transmission box of the thread rolling machine is insufficient and the water resistanceis poor and the service life is short is solved.
