[0026] See also Figure 1-Figure 6 There are two feeding mechanisms 1, and the two feeding mechanisms 1 are located on the same side of the steering mechanism 2, and the feeding mechanism 1 and the steering mechanism 2 are located on the same horizontal line. The controller 3 is arranged on the outside of the steering mechanism 2, and the controller 3 is respectively electrically connected to the first electric push rod 10, the servo motor 12 and the second electric push rod 25 by wire.

[0027] Working principle: During use, the control program is first set through the controller 3, and the servo motors 12 at the bottom ends of the two sliding adjustment rods 8 rotate in opposite directions. Then, one end of the stainless steel pipe raw material 4 is pulled to the steering mechanism 2 by external force, and the stainless steel pipe raw material 4 is inserted into the inner side of the outer support frame 24, and the stainless steel pipe raw material 4 is located between the two sets of symmetrically arranged third steering rollers 29, and the stainless steel pipe raw material 4 is located between the first steering roller 23 and the second steering roller 27. Then, the stainless steel pipe raw material 4 is pulled between the two sliding adjustment rods 8, and then the corresponding stainless steel pipe raw material 4 is selected according to the diameter of the stainless steel pipe raw material 4. The first rubber sleeve 17 is selected according to the diameter of the stainless steel pipe raw material 4 and the size of the first clamping groove 18, and then the first rubber sleeve 17 is inserted into the outer side of the internal support 15, and the first limiting protrusion 19 is inserted into the outer side of the limiting groove 16, and then the fixing plate 20 is installed on the top of the internal support 15 by bolts.

[0028] After the adjustment is completed, the positioning of the stainless steel pipe raw material 4 is started, and the second electric push rod 25 is controlled to extend through the controller 3. The telescopic end of the second electric push rod 25 pushes the lifting plate 26 to move downward, and the movement of the lifting plate 26 drives the second steering roller 27 to move downward to the top of the stainless steel pipe raw material 4. At this time, the top of the stainless steel pipe raw material 4 is close to the bottom of the second steering roller 27, and the bottom of the stainless steel pipe raw material 4 is close to the top of the first steering roller 23. Then, the first electric push rod 10 is controlled to retract through the controller 3, and the telescopic end of the first electric push rod 10 pulls the bottom ends of the two push-pull rods 11 to move downward, and the The bottom end of the push-pull rod 11 is fixedly installed on the telescopic end of the first electric push rod 10, and the top end of the push-pull rod 11 is fixedly installed on the middle part of the bottom end of the sliding adjustment rod 8. The movement of the bottom end of the push-pull rod 11 pulls the sliding adjustment rod 8 to slide on the first slide rod 7 toward the middle part of the first slide rod 7. The movement of the sliding adjustment rod 8 drives the support turntable 14 to move, thereby driving the first rubber sleeve 17 on the outside of the internal support 15 to move. When the first rubber sleeve 17 moves to the outside of the stainless steel pipe raw material 4 and is close to the first clamping groove 18, it stops moving. At this time, the two sides of the stainless steel pipe raw material 4 are respectively squeezed by the first rubber sleeve 17.

[0029] After the positioning is completed, the loading operation can be carried out. The servo motor 12 is started by the controller 3. The driving end of the servo motor 12 drives the supporting turntable 14 to rotate. The rotation of the supporting turntable 14 drives the internal support 15 to rotate. The rotation of the internal support 15 drives the first rubber sleeve 17 to rotate. Since the stainless steel pipe raw material 4 is located on the inner side of the first clamping groove 18 and the outer side of the first rubber sleeve 17 is close to the outer side of the stainless steel pipe raw material 4, the rotating first rubber sleeve 17 under the action of friction drives the stainless steel pipe raw material 4 to move away from the steering mechanism 2, thereby realizing the loading operation.
