[0045] The working principle of the present application: in the feeding stage, according to the length of the stainless steel pipe to be processed, the length adjusting motor 141 drives the length adjusting base 14 to move transversely along the second base 13, adjusts the distance between the left and right two second bases 13, and then the second motor 131 drives the bidirectional screw 132 to rotate, so that the first transverse base 134 on both sides moves towards the middle, and then the first transverse base 134 drives the upper clamps 4 to approach each other, in combination with the rubber strips 441 arranged on the roller 44 to contact the surface of the stainless steel pipe, realizing the fixing effect of the stainless steel pipe, and then the feeding motor 1121 at the bottom of the right second base 13 is driven to drive the feeding base 112 to move along the feeding guide rail 111, so that the stainless steel pipe moves to the right, and the stabilizing mechanism 3 penetrates into the stainless steel pipe, under the action of the four supporting springs 32, the guide wheels 35 at the ends of the swing arms 34 tightly abut the inner wall surface of the stainless steel pipe, and through the supporting effect of the stabilizing mechanism 3, the synchronous screw 1251 and the first limiting rod 1252 are prevented from being excessively bent due to gravity, so that the subsequent inner supporting mechanism 2 moves to the corresponding position as needed.

[0046] In the processing stage, after the stainless steel pipe is driven by the right clamp 4 to move to the processing position, the stamping frame 124 drives the supporting frame 51 at the top thereof to move along the transverse screw 123 under the driving action of the transverse motor 1211, moves the stamping part 5 to the preset position according to the processing needs, rotates the punch 56 required for processing to the processing position through the conversion motor 54 at the side edge of the electric push rod 52, pushes the fixed plate 53 and the rotating disc 55 downward through the electric push rod 52, so that the punch 56 performs the required processing operation on the surface of the stainless steel pipe, and after the processing is completed, the electric push rod 52 is retracted to the original position, so as to perform turnover or replace the punch 56. The metal waste generated in the processing process falls on the conveyor belt 16 at the bottom of the device, the pushing arm 152 at the bottom of the linkage plate 15 is driven by the stamping frame 124 to move, so that the pushing arm 152 continuously pushes the inclined rack 161 on the conveying belt 16 in left and right adjustment, and then realizes conveying of the metal waste generated in the processing process, prevents the metal waste from accumulating in the device, and ensures stable operation of the equipment.

[0047] Synchronous support stage, while the horizontal moving motor 1211 drives the horizontal moving screw 123 to rotate, the synchronous screw 1251 is driven to rotate synchronously through the transmission of the synchronous belt box 125, and then the inner support mechanism 2 is driven to move synchronously along the synchronous screw 1251; under the action of the synchronous belt box 125, the inner support mechanism 2 and the stamping part 5 move synchronously, so that the inner support mechanism 2 is always below the machining position of the stamping part 5; when the inner support mechanism 2 moves to the machining position, the driving ring 23 on both sides is driven to rotate by the support motor 241, the slope on the end of the slope block 231 and the roller 222 on the bottom of the support bush 22 are in contact, and then the support bush 22 on both sides of the inner support mechanism 2 is driven to move away from the axis, the rubber block 223 arranged on the support bush 22 is attached to the inner wall of the stainless steel pipe, and under the support of the support bush 22 on both sides, it is ensured that the stainless steel pipe will not be deformed due to uneven stress during machining.

[0048] The turning stage is that the rollers 44 on both sides are driven to rotate by the turning motor 42, and then the stainless steel pipe is turned to the next machining position according to the requirement, and then the same machining operation is performed.

[0049] After machining, the clamp 4 on the upper part of the right second base 13 drives the stainless steel pipe to exit, and the machining operation is completed.
