The invention relates to a feeding and fetching machine, in particular to a feeding and fetching machine in the process of heat treatment of pipes and a treatment method of the pipes. The feeding and fetching machine comprises a worktable and supporting columns; the worktable is fixed to the upper portions of the supporting columns; sliding rails are arranged on the table surface of the worktable, distance scales are arranged on the sliding rails, and grooves are formed in the sliding rails; two lead screw systems which are symmetrical along the vertical direction of the worktable and can reciprocate along the sliding rails are arranged on the worktable, and convex rails embedded in and matched with the grooves are arranged on the bottom of the lead screw systems; and two hydraulic systems which are symmetrical along the vertical direction of the worktable are arranged on the worktable. The pipe feeding and fetching machine in the process of heating treatment is reasonable in structure design, high in degree of automation, strong in safety and simple in operation, can carry out feeding of pipes with different diameters, can achieve the purpose of fetching after heating treatment, improves the efficiency of heating treatment of the pipes, and thereby providing reliable basis for the application of the pipes in the field of engineering.
