The invention discloses a steel pipe equal-distance cutting device with feeding and arranging functions. The steel pipe equal-distance cutting device comprises a first conveying belt and a second conveying belt arranged at the left side position of the first conveying belt. A discharging unit is arranged on the first conveying belt. A cutting unit is arranged between the first conveying belt and the second conveying belt. The steel pipe equal-distance cutting device with the feeding and arranging functions has the beneficial effects that through a rotation discharging structure, steel pipes can be conveyed out of a box according to a certain frequency to the first conveying belt to be cut; the number of the steel pipes conveyed out of the box every time can be changed through a dischargingcontrol structure; jamming of the steel pipes in the box can be prevented through an auxiliary discharging structure, the steel pipes can be stably output, and the production efficiency is guaranteed; through cooperation of a cutting structure and a transportation structure, the steel pipes are placed on the second conveying belt to be conveyed away after being cut; and through the continuous working cutting device, cutting accuracy is guaranteed, labor force is liberated, and the labor cost and material waste are reduced.
