The working principle is as follows:

s1: firstly, the left end of a tube body 9 is movably clamped on a guide disc 7, the right end of the tube body 9 is inserted into a processing channel 10, and meanwhile, the right end of the tube body 9 is sleeved on the outer wall of a stamping device 18, so that the horizontality of the tube body 9 can be ensured, the tube body 9 can be supported, then two groups of first electric telescopic rods 12 are enabled to extend outwards through an electric cabinet 22, a clamping plate 13 can be driven to clamp the upper side wall and the lower side wall of the tube body 9, the limiting performance of the tube body 9 is ensured, and the tube body 9 is prevented from moving;

s2: then the electric cabinet 22 is used for driving the second electric telescopic rod 16 to extend outwards, the push plate 17 can be driven to extrude the bearing plate 20, therefore, the bearing plate 20 transmits the thrust to the guide post 182 through the push rod 19, and with the leftward movement of the guide post 182, not only can the elastic band 186 be stretched and deformed, but also the arc-shaped guide block 183 can be pressed upwards, so as to drive the processing post 184 to extend out of the protection box 181, and meanwhile, the return spring 185 is compressed, so as to punch the inner wall of the pipe body 9 by the pushing force transmitted to the processing column 184, a convex point is formed on the outer wall of the tube body 9, when the second electric telescopic rod 16 returns, the guide post 182 loses the leftward power, the elastic force generated by the reset spring 185 acts on the guide post 182 through the arc-shaped guide block 183, meanwhile, the resilience force generated by stretching the elastic band 186 can push the guide post 182 to reset, so that the processing of a salient point station on the outer wall of the tube body 9 can be completed;

s3: when salient points are manufactured in the circumferential direction of the pipe body 9, the electric cabinet 22 controls the two groups of first electric telescopic rods 12 to retract and reset, then the electric control box 22 drives the stepping motor 14 to rotate in the positive direction, so that the protective shell 15 can be driven to rotate clockwise slowly through the speed reducing action of the speed reducer, the stamping device at the left end part of the protective shell 15 can be driven to rotate synchronously, the processing position of the tube body 9 corresponding to the processing post 184 can be changed, the hall sensor 21 can detect the rotation angle of the protective shell 15 at any time, thus, when the preset rotation angle is reached, the electric control box 22 can control the stepping motor 14 to stop rotating, then the electric cabinet 22 controls the two groups of first electric telescopic rods 12 to extend outwards to clamp the pipe body 9 again, therefore, the step in the step S2 is repeated to complete the manufacture of the salient points on the outer wall of the other group of pipe body 9, and by parity of reasoning, the manufacture of the salient points in the circumferential direction of the pipe body 9 can be completed;

s4: when salient points are manufactured in the length direction of the tube body 9, the electric cabinet 22 controls the two groups of first electric telescopic rods 12 to retract and reset again, the electric cabinet 22 controls the driving motor 4 to rotate in the forward direction, the screw 6 can be driven to rotate slowly and clockwise through the speed reduction effect of the reduction gearbox 5, so that the guide disc 7 is driven to move rightwards along the length direction of the screw 6 through the screw connection effect of the screw 6 and the guide disc 7, meanwhile, the two groups of guide rods 8 can limit the guide disc 7 to prevent the guide disc 7 from rotating around the screw 6, and therefore, the linearity of left and right movement of the guide disc 7 can be ensured, so that the tube body 9 can be pushed to move rightwards when the guide disc 7 moves, meanwhile, the moving distance of the tube body 9 can be determined according to a scale on the front side wall of the processing seat 2, then the electric cabinet 22 can control the driving motor 4 to stop rotating, and then the electric cabinet 22 controls, then, the steps of S2 and S3 are repeated in sequence to finish the processing of a new group of bumps;

s5: in a similar way, the step of S4 is carried out again and bump preparation can be realized to the outer wall length direction of body 9, and after the preparation was accomplished, two sets of electric telescopic handle 12 reset, and electric cabinet 22 control driving motor 4 reverses, can drive the positioning disk 7 and reset, then can lift body 9 off can, the simple operation, the precision is high.
