The bearing of the three truing plate shaft 205 is preferably a one-way bearing to ensure that the three truing plate shaft 205 can only rotate in one direction (such as left-handed). When the spline wheel 402 rotates, the outer peripheral surface of the bearing of the third truing plate shaft 205 is always attached to the outer surface of the spline wheel.

As shown in fig. 5A, the operation of the tooth forming machine to the rightmost point, i.e., the operation of the tooth forming unit and the tooth pre-shaper to the rightmost point, may be considered as the initial position. The inclined push plate 704 moves leftwards along the direction of the left arrow of the reciprocating position, because the other end of the shaping plate tension spring 202 on the horizontal sliding plate 502 is hung on the screw of the horizontal sliding plate limiting block 504, the inclined push plate limiting wheel 705 is tightly attached to the right end face of the inclined push plate 704, the whole mechanism on the horizontal sliding plate 502 is further made to move leftwards along with the inclined push plate 704, and when an auxiliary limiting part (such as a screw head section) arranged on the horizontal sliding plate 502 contacts the horizontal sliding plate limiting block 504, the horizontal sliding plate 502 stops following and keeps a static state.

As shown in fig. 5B, which is a schematic structural diagram of the tooth forming device and the tooth blade pre-shaping device in a first intermediate state, starting from the state of fig. 5A, the inclined push plate 704 continues to move leftward, and when moving to the state of fig. 5B, the ratchet plate hook 4013 just contacts one tooth surface at the upper end of the ratchet 401, and at the same time, the blade 701 is about to leave the processing surface of the aluminum profile 6. When the inclined push plate 704 moves leftwards, the ratchet wheel 401 is driven to rotate leftwards.

As shown in fig. 5C, the configuration of the relieving device and the tooth blade pre-shaping device in the second intermediate state is schematically illustrated, at this time, the ratchet wheel 401 drives the spline wheel 402 to rotate, the convex portion 4021 of the spline wheel 402 presses the second shaping plate shaft 204, the whole shaping plate 201, and the shaping tool 2 together to the lowest point, and the shaping tool 2 presses a tool mark 103 with a predetermined depth on the processing surface of the aluminum profile 6.

The inclined push plate 704 continues to move leftward, and the ratchet 401 continues to rotate to the state shown in fig. 5D under the driving of the ratchet plate hook 4013, which is a schematic structural diagram of the third intermediate state of the tooth forming device and the tooth pre-shaping device. At this time, the ratchet plate hook 4013 is about to be disengaged from the ratchet wheel 401, the concave portion 4022 of the spline wheel 402 corresponds to the second truing plate shaft 204, the truing tool 2 is lifted to the highest point, and the scraper 701 moves back to a position above the scraping surface of the aluminum profile 6 (i.e., away from the scraping surface of the aluminum profile 6).

As shown in fig. 5E, the structure of the tooth forming device and the tooth blade pre-shaping device in the fourth intermediate state is shown, and the structure of the inclined push plate 704 moves to the leftmost point to the left is also shown. In the process that the inclined push plate 704 moves from the left side of fig. 5D to the left side of fig. 5E, the tooth forming machine moves the aluminum profile 6 one step to the right, and then tooth forming is performed next. Subsequently, the inclined push plate 704 moves to the right to the state shown in fig. 5A, in this process, the blade 701 performs one-time tooth relieving, when the ratchet plate hook 4013 meets the ratchet wheel 401, the blade is lifted up around the ratchet plate shaft 4012 under the guidance of the inclined surface, the ratchet plate compression spring 4014 is compressed, and after the ratchet plate hook 4013 passes over the ratchet wheel 401, the ratchet plate hook 4013 is reset under the action of the ratchet plate spring 4014. When the right end surface of the inclined push plate 704 contacts with the inclined push plate limiting wheel 705, all the mechanisms on the horizontal sliding plate 502 are driven to move rightwards together until the state shown in fig. 5A is reached. Then, the next cycle starts.
