[0003] The inventor found that when performing tooth extrusion processing on the oxygen-free copper tube body, one end of the oxygen-free copper tube body is usually manually held to sleeve the other end of the oxygen-free copper tube body on the outer surface of the inner tooth extrusion roller on the fixed plate, and then the cylinder is started to drive the sliding plate and the outer tooth extrusion roller to move downward to squeeze the oxygen-free copper tube body on the outer surface of the inner tooth extrusion roller, so that the tooth shape on the outer surface of the inner tooth extrusion roller is meshed with the tooth shape on the outer surface of the outer tooth extrusion roller and extruded on the outer surface of the oxygen-free copper tube body. Then, the tooth processing machine is used to start the driving assembly inside the fixed plate and the sliding plate to drive the inner tooth extrusion roller and the outer tooth extrusion roller to rotate, so that the tooth extrusion processing can be performed on one end of the oxygen-free copper tube body. Since the oxygen-free copper tube body may shake and deviate due to manual support, the extruded tooth shape may be offset and misaligned, so that it may not be able to be connected later, resulting in the oxygen-free copper tube body after processing being unusable, thereby increasing the number of defective products.

By setting the anti-collision block 46, one side of the limit arc block 45 can be protected, so that when the oxygen-free copper tube body 10 is limited so that it is quickly sleeved on the outer surface of the inner tooth extrusion roller 6, it is not easy to damage the two limit arc blocks 45 after impacting on one side, thereby improving the service life of the limit arc block 45.

[0037] The working principle is as follows: when using the tooth profile processing machine 1 to perform tooth extrusion processing on the oxygen-free copper tube body 10, first clamp the T-shaped frame 21 and the limiting rod 37 in the inner walls of the installation groove 31 and the limiting groove 38 respectively, and then manually hold the screw block 35 to screw the bolt 34 from the inner wall of the screw hole block 33 so that it is screwed into the inner wall of the thread groove 32, so that the T-shaped frame 21 and the bottom plate 41 can be fixed and limited on one side of the tooth profile processing machine 1, and then according to the size of the oxygen-free copper tube body 10 to be processed, start the electric telescopic rod 213 to drive the support block 214 to move upward to a certain position, and manually hold one end of the oxygen-free copper tube body 10 to place it on the support block 214 is pushed to one side, so that it drives the other end to abut against the inner wall of the two limiting arc blocks 45, and the limiting arc blocks 45 will play a role of limiting and guiding it, so that it is sleeved on the outer surface of the inner tooth extrusion roller 6 on the fixed plate 5. When the oxygen-free copper tube body 10 is stuck in the inner wall of the two limiting arc blocks 45 and slides, it will squeeze the two limiting arc blocks 45, so that it moves to both sides, driving one end of the U-shaped frame 43 to slide outward in the circular groove 42 on the bottom plate 41 to a certain position, so that the second spring 44 is stretched, so that it can be adjusted according to the size of the oxygen-free copper tube body 10 that needs to be processed, so that it can be used for oxygen-free copper tube bodies 10 of different sizes. 0 for limit alignment, saving the time of alignment and sleeve setting, improving the processing efficiency, and then starting the servo motor 27 to drive the winding roller 28 to rotate on the bracket 26, so that it can wind and tighten the draw rope 212. The draw rope 212 will pass through the round hole 23 under the limit action of the guide roller 29 to pull the slide bar 24, so that the two slide bars 24 move in opposite directions in the inner walls of the two slide grooves 22, thereby driving the clamping block 25 to clamp and fix the oxygen-free copper tube body 10. At the same time, the limit telescopic rod 210 and the first spring 211 will be stretched between the slide bar 24 and one side of the slide groove 22, so that it is not easy to shake during the tooth extrusion process. The situation of deviation occurs, thereby avoiding the deviation and dislocation of the extruded tooth shape, reducing the number of defective products produced during processing, and then starting the cylinder 9 to drive the sliding plate 7 and the external tooth extrusion roller 8 to move downward to squeeze the oxygen-free copper tube body 10 on the outer surface of the internal tooth extrusion roller 6, so that the tooth shape on the outer surface of the internal tooth extrusion roller 6 is meshed with the tooth shape on the outer surface of the external tooth extrusion roller 8 and extruded on the outer surface of the oxygen-free copper tube body 10, and then starting the fixed plate 5 and the driving component inside the sliding plate 7 through the tooth processing machine 1 to drive the internal tooth extrusion roller 6 and the external tooth extrusion roller 8 to rotate, so that one end of the oxygen-free copper tube body 10 can be tooth extruded.
