In order to optimize the manufacture and use of clockwork wheels, document CH-B-6 7 7 1 6 8 proposes a wheel, which includes installation A pinion wheel, this assembly includes a bearing, which is a recess for accommodating the intermediate shaft or enters into a concave intermediate shaft. Plates, pinions, and bearings use plastic flow as a single component, including forging and pressing of pieces of material suitable for cold flow. However, the wheels shown in this document are simple gear trains, which include a plate with a traditional set of teeth (a little more) and a pinion on the plate. The number of pinions is small (6 in this example). Teeth) > These teeth have the same orientation as the teeth on the board. The above document does not point out or suggest a method that can be used to make a more precise setting wheel, that is, the second file of the wheel is a horizontal file, including a size much smaller than the simple clockwork wheel pinion described in the document Of multiple teeth. This is how to try to apply cold flow method to stamped steel plate to get more complicated time or date setting wheel than simple wheel structure (only one plate and one pinion). The applicant of the present invention has surprisingly set out to produce well-manufactured components' which breaks the past expectations, and the methods used have obtained surprising results, far from those imaginable in the past.

Description of the invention P) The handle 20 can slide into a plate 21 and has a locked position which is pushed and pulled out by a handle spring 22. The rotary handle includes a pinion 2 3 meshing with the file teeth 5, 19 of a setting wheel 1, 2, and the setting wheel and its manufacturing are the object of the present invention. The setting wheels 1, 2 include a plate 3 surrounding one of the teeth 4 of the first series, and a teeth 5 '1 of the second series arranged at a right angle to the plate 3. The setting wheels 1 and 2 mesh with an action mechanism (not shown). This action mechanism drives a hollow pinion 2 4 and on the other hand drives a GD time wheel 2 5 which is attached to a tube 2 6, an hour hand (not shown) is assembled on the tube 26. The hollow wheel 2 4 supports a minute hand (not shown) and a minute wheel 2 6 (friction assembly). FIG. 1 also shows the second wheel 27 which is assembled to a shaft 28, and the second hand (not shown) is assembled on the second wheel 27. When the time setting handle 20 is turned in the pulled-out position, the setting wheels 1, 2 are driven 'so that the minute and hour hands are driven by the action mechanism during this operation' the minute wheel 2 6 slides on the hollow wheel 24, and the latter It is fixed by the drive mechanism (not 75). The setting wheel] _, 2 includes a central hole 17 and the intermediate shaft 2 9 assembled to the board 21 is passed through the central hole 1 7 = > The setting wheel 1 and 2 are freely combined with the intermediate shaft 2 9. An action mechanism bridge 30 covers the time setting mechanism. The setting wheels 1 and 2 and the manufacturing method thereof will now be described. The first embodiment of the setting wheel 1 is shown in Figs. 2 and 3. As mentioned above, the setting wheel includes a plate 3 surrounding one of the first series of teeth 4 and a brother at a right angle to the plate 3-Series 5 Tooth 5 is also referred to as a condyle sitting tooth. The first embodiment is characterized in that the teeth 5 of the second series and those shown in FIG. 3 are rounded at the top of each tooth 5 but may be flat, which will be described later.

Description of the invention $) The second embodiment of the setting wheel 2 is shown in Fig. 4, which is the same as the first The difference between one embodiment is only that the tooth 19 of the file tooth is cut by the conventional method using the set wheel. The second embodiment will be described later. The method on which the above two embodiments of the present invention are based includes the following steps, as shown in FIGS. 5 to 12. First, the first step is to provide a steel plate 6 suitable for stamping. For example, the steel plate is cold-formed, with a width of 16 mm and a thickness of 0. 3 mm. It has three guides that are worn by a progressive forging die. Holes and guide holes allow the steel plate to accurately find the center between different dies and punches, where the punches follow each other in a progressive forging die. The first step is shown in Figs. 5 and 6, where a ring 7 'is cut out of the steel plate 6 and the inner diameter 8 of the ring 7 surrounds a plate 9, and the required clockwork wheel is taken out from the plate 9. As shown in FIG. 5, the disc 9 is kept connected to the steel plate 6 by a certain number of bridges 10 (that is, the four bridges 10 shown in the figure as an example). The sectional view of the tool used for this work is shown in Fig. 6. Fig. 6 also shows that the steel plate 6 'after cutting the circular ring 7 is cut along the line V I-V I in Fig. 5. The cutting tool includes a die 32 passing through a four-ring section 33 and a punch 34 having a corresponding section 35 interrupted by a four-bridge 36. The second step is shown in Figs. 7 and 8. As shown in Fig. 7, after this operation, the disc 9 has a second series of teeth 5 at right angles to the disc. The cross-section of the tool used in the second step is shown in Fig. 8 '. Fig. 8 also shows the steel plate 6 after flowing, and the cutting is along the line V I I I _ V I I I in Fig. 7. The flow operation is as follows. A die 12 with a plurality of perforations 1 3 is placed on one of the trays 9 1 1, and a flat surface 15 of a cylinder 16 is pressed against the other face 1 4 of the tray 9 to make the steel flow suitable for stamping. China National Standard (CNS) A4 specification (210x297 public love) (This page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs--9-A7 409201 B7 _ V. Description of the invention f) Enter the holes 1 3 of the mold 1 2. As in the following figures, Figs. 7 and 8 show a second series of teeth 5. To make these teeth, the die 12 is provided with a plurality of cylindrical holes 13. This non-traditional cylindrical tooth profile can provide a smoother motion of the movement than a traditional cutter. The harmonious movement obtained in this way is characterized by no friction, which ensures smoother setting between holdings. It is mentioned here that the number of teeth of the plurality of teeth 5 considered here is large, and its support is not related to the small number of teeth (5 or 6) forming the pinion of the clockwork mechanism. Thus, as described above, with amazing and unexpected effects, the method results in a large number of teeth, and the size of these teeth is small. For example, there are 12 teeth in the second series of the setting wheel, and the diameter of the cylinder does not exceed 0.2 mm. The height of the teeth 5 can be controlled by the force with which the cylinder 16 is pressed against the surface 14 of the disc 9. However, in some specific examples, the height is limited by the arrangement of the pins 18 of the holes 12 of the die plate 12. Regardless of which one is selected, the purpose of the first step in this method to cut a ring 7 on the steel plate should be understood. In fact, during compression, the material not only flows into the holes 12 of the die 12 to form the teeth 5, but also It flows laterally in the longitudinal direction of the steel plate 6. By arranging a space around the disc 9, the ring 7 has a space for excess material to flow, and the formation of the teeth 5 can be more closely controlled. After compression of the cited example, the thickness of the disc center is between 0.3 and 0.2 m. The holes I 3 of the die plate 12 are not limited to cylindrical holes arranged in a circle. These holes can actually be shaped holes to form a second series of teeth, as shown in FIG. 14 by the teeth s teeth 1 9 It is also shaped by material flow, and its shape is like a traditional cutter. This paper size uses the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ------ Line (Please read the Jiang Yi matter on the back before filling in this page> Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -10- A7 409201 _ B7___ V. Description of the invention §) The third step is shown in the figure 9 and 1 〇, as shown in FIG. 9, a hole 17 is cut out in the center of the plate 9. As shown in FIG. 1, the hole 17 is used to fix the setting wheel 1 and 2 to the plate 2 1 and the intermediate shaft 2. 9 free rotation. The section of the tool used for this operation is shown in Fig. 10, and Fig. 10 also shows the situation where the steel plate 6 has been cut out of the hole 17 and its cutting is along the line X-X in Fig. 9. The cutting tool includes a die 40 provided with a perforation 41 and a punch 4 2 formed by cutting a block 4 3. The punch 4 2 can cut out the hole 17 of the disk 9. The block 4 3 is provided with an annular hole 4 4 to leave space for the teeth during the cutting operation. The fourth step is shown in Figures 11 and 12. In this fourth and final step, the completed wheel 1 is taken out. To achieve this, as shown in Figure 11, the first series of teeth 4 are cut on the disc 9, This cutting naturally causes the wheel to be separated from the steel plate 6. The section of the tool used for the latter operation is shown in Fig. 12, and Fig. 12 also shows the steel plate 6 and the wheel 1 'after the wheel has been cut out. The cutting is along the line X I I-X I I in Fig. 11. The cutting tool includes a die 50, and the cutting tooth 51 in the die 50 is to be copied on the wheel, and a punch corresponding to the tooth 53 is provided. As shown in FIG. 12 ', after the cutting is completed, the teeth 4 are also completed around the wheel 1 while being separated from the disc 9. In the second step above, 16 examples of file teeth 5 wheels are included. This wheel has 26 surrounding teeth 4 after the fourth step is completed. The method proposed here has its advantages. Regardless of whether the tooth 5 is cylindrical or profiled, its advantage is that instead of the conventional mechanism that will set the burr of the wheel, the first cutting operation of cutting the surrounding teeth around the board should be applied. Carry out the second cutting operation. The method of using material flow is cheaper because it takes less time to manufacture the setting wheel.
