after the fixation is finished, the movable frame 5 can be controlled to move forwards and backwards under the drive of the first screw rod 301 by controlling the first driving motor 3, so that different steel pipes 10 to be cut can be cut, the mounting mechanism can be controlled to move along the length direction of the steel pipes 10 to be cut under the drive of the second screw rod 901 by controlling the second driving motor 9, the longer steel pipes 10 to be cut can be cut for multiple times, the lifting of the hydraulic cylinder 4 can be controlled, the lifting of the servo motor 6 can be controlled by controlling the lifting of the hydraulic cylinder 4, the overall stability of the cutting wheel 602 is improved when the auxiliary sliding block 403 and the limiting sliding rod 402 are arranged to cut the steel pipes 10 to be cut, and the steel pipes 10 to be cut can be cut after the servo motor 6 is started;
when needs carry out cutting process many times to longer steel pipe 10 that waits to cut, spacing fixture 7 on the mounting plate 8 of lateral wall fixed connection on with the lathe body 1 need not to adjust, the spacing fixture 7 on the mounting plate 8 that sets up for sliding between the lateral wall on the lathe body 1 need be released the centre gripping to this end steel pipe 10 that waits to cut, start second driving motor 9, under the drive of second lead screw 901, the mounting mechanism can drive this mounting plate 8 through L type connecting plate 203 and remove, when waiting to remove the steel pipe tip of non-cutting department, can control spacing fixture 7 and carry out automatic fixation to this end, both ends through waiting to cut steel pipe 10 are fixed, can carry out firm cutting to it, avoided current device unilateral fixed, its fixed effect is relatively poor, easily lead to the steel pipe to take place the deviation in cutting process, then lead to the condition of steel pipe incision deformation to appear, also need not artifical the assistance simultaneously, overall efficiency is higher.
