The metal pipe 110 can be fixed at the corresponding cutting position under the clamping action of the clamping assembly 1, and then the cutting machine 102 is operated to perform the initial cutting process on the initial position of the corresponding cutting position of the end of the metal pipe 110. Then, after the initial cutting process is completed, the controller 103 provided on the cutting table 101 is used to control the driving part 3, so that the third clamping piece 23 arranged between the first clamping piece 11 and the second clamping piece 12 of the feeding assembly 2 is controlled to feed the metal pipe 110 on the first clamping piece 11 and the second clamping piece 12 in the direction of the cutting machine 102 on the cutting table 101 for a corresponding length, specifically from Fig. 1 and Fig. 2As can be seen from the drawings, the driving component 3 is provided in the ball screw and sliding table structure, which comprises a driving motor 31 mounted on one side of the rack 100, a screw shaft 32 rotatably arranged in the rack 100 and connected with the driving motor 31, a sliding block 33 mounted on the bottom of the fixed seat 22, and a sliding rail 34 arranged on the sliding seat 1011 for the sliding of the fixed seat 22.
