The invention discloses a screw thread rolling machine. The machine comprises a feeding mechanism, wherein one end of the feeding mechanism is fixedly provided with a storage box, and falling stop blocks are fixedly arranged at the upper end of the feeding mechanism; discharging through grooves are formed in the ends, close to the storage box, of the falling stop blocks, a feeding channel is fixedly arranged at the end, away from the discharging through grooves, of the falling stop blocks, a feeding air cylinder is fixedly arranged on the feeding channel, and a discharging push block is fixedly arranged on the feeding air cylinder; and an electric control box is fixedly arranged on the outer side of the feeding mechanism, a maintenance door is movably arranged on the electric control box,a function key is fixedly arranged at the end, adjacent to the maintenance door, of the electric control box, and an adjusting knob is fixedly arranged on the outer side of the function key. According to the screw thread rolling machine, the feeding mechanism capable of automatic feeding is added, so that an operator can be liberated, only raw materials in the storage device are required to placeon the feeding mechanism, therefore the direct contact between the operator and the equipment is reduced, and the operator is better protected.
