A hairspring forming mechanism Technical Field

[0001] This application relates to the field of hairspring processing technology, and in particular to a hairspring forming mechanism. Background Technology

[0002] Currently, the hairspring is a precision mechanical component made of extremely fine metal wire in a spiral shape. In clocks, it works with the balance wheel to control the timekeeping rhythm; in measuring instruments, it generates elastic reaction torque to measure electrical parameters; in automotive safety systems, it connects the main airbag to the airbag wiring harness; in the aerospace field, it stabilizes the gyroscope rotor; and in the field of precision manufacturing, it controls the speed and stability of moving parts.

[0003] During the production process, workers wind the hairspring around two positioning posts, and then use a cutting tool to cut the hairspring. After the hairspring is cut, workers separate the individual hairsprings and then wind them back onto the hairspring posts.

[0004] Regarding the aforementioned technologies, the inventors believe that cutting multiple hairsprings is quite difficult, as it is hard to cut several hairsprings at once, and the lengths of the cut hairsprings are not uniform, which affects the subsequent processing of the hairsprings. Summary of the Invention

The sliding frame is threadedly connected to the screw. The drive motor is mounted on the frame, and the output shaft of the drive motor is connected to the screw.

[0011] Furthermore, the sliding frame is provided with a positioning block and a positioning cylinder. The positioning cylinder is installed on the sliding frame, and the positioning block is installed on the positioning cylinder. A positioning groove is formed on the positioning block, and the positioning groove is open towards the side close to the forming rod.

[0012] Furthermore, the cutting assembly includes a cutting cylinder and a cutting blade. The cutting cylinder is vertically mounted on the sliding frame, and the cutting blade is mounted on the cutting cylinder with the cutting blade facing towards the side close to the forming plate.

[0013] Furthermore, a lifting cylinder is provided on the frame, the lifting cylinder is vertically mounted on the frame, and the forming plate is mounted on the piston rod of the lifting cylinder.

[0014] In summary, this application includes at least one of the following beneficial technical effects of the hairspring forming mechanism:

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The present application will be further described in detail below with reference to Figures 1-3.

[0024] This application discloses a hairspring forming mechanism.

[0025] Referring to Figure 1, a hairspring forming mechanism includes a frame 1, a forming plate 2 disposed on the frame 1, a forming component 3 and a cutting component 4 disposed on the frame 1, the forming component 3 forming the hairspring, and the cutting component 4 cutting the formed hairspring.

[0026] Referring to Figure 2, the molding plate 2 is generally rectangular, and a guide wheel 21 is provided on one side of the molding plate 2 along the length direction. Two guide wheels 21 are spaced apart along the width direction of the molding plate 2, and the guide wheels 21 are rotatably mounted on the molding plate 2.

[0027] Referring to Figures 1 and 3, the molding assembly 3 includes a sliding frame 31, which slides along the length of the molding plate 2. To improve the ease of sliding the sliding frame 31 on the frame 1, a drive motor 32 and a screw 321 are provided on the frame 1. The screw 321 is horizontally positioned and rotatably mounted on the frame 1. One end of the screw 321 passes through the sliding frame 31, and the screw 321 is threadedly connected to the sliding frame 31. The drive motor 32 is mounted on the frame 1, and one end of the output shaft of the drive motor 32 is connected to the screw 321. In use, the drive motor 32 drives the screw 321 to rotate forward or backward. As the screw 321 rotates forward or backward, the sliding frame 31 reciprocates along the length of the molding plate 2.

[0028] Referring to Figure 3, the molding assembly 3 includes a molding cylinder 33 and a molding rod 331. The molding cylinder 33 is vertically mounted on the molding plate 2, with one end of the piston rod of the molding cylinder 33 facing towards the side closer to the molding plate 2. Furthermore, the molding rod 331 is located between two guide wheels 21, with one end connected to the molding cylinder 33 and the other end extending towards the side closer to the molding plate 2. In use, the hairspring passes through one side of the two guide wheels 21, and then the molding cylinder 33 drives the molding rod 331 to extend towards the side closer to the molding plate 2. Subsequently, the drive motor 32 drives the screw 321 to rotate. During the rotation of the screw 321, the sliding frame 31 drives the molding rod 331 to pass between the two guide wheels 21, thereby causing the hairspring to form a U-shape on the molding plate 2.

[0029] Referring to Figure 3, the cutting assembly 4 includes a cutting cylinder 41 and a cutting blade 42. Two cutting cylinders 41 are spaced apart on the sliding frame 31, and the two cutting cylinders 41 are vertically mounted on the sliding frame 31, with one end of the piston rod of the cutting cylinder 41 facing towards the side closer to the forming plate 2. The cutting blade 42 corresponds to the cutting cylinder 41 and is mounted on the cutting cylinder 41. After the hairspring is formed on the forming plate 2, the cutting cylinder 41 drives the cutting blade 42 to move towards the side closer to the forming plate 2. When the cutting blade 42 presses against the forming plate 2, it cuts off the end of the hairspring. Since there are two cutting blades 42 spaced apart, the lengths of the hairsprings cut on the forming plate 2 are all the same.

[0030] Furthermore, a positioning cylinder 34 is provided on the sliding frame 31. The positioning cylinder 34 is horizontally mounted on the sliding frame 31, and one end of the piston rod of the positioning cylinder 34 faces the side closer to the forming rod 331. In addition, a positioning block 341 is provided at one end of the piston rod of the positioning cylinder 34. The positioning block 341 has a positioning groove 342 with a U-shaped cross-section, and the U-shaped opening of the positioning groove 342 faces the side closer to the forming rod 331. After the hairspring is formed on the forming rod 331, the positioning cylinder 34 drives the positioning block 341 to move towards the side closer to the forming rod 331. The hairspring is clamped between the forming rod 331 and the positioning block 341. After the hairspring is clamped, the cutting cylinder 41 drives the cutting blade 42 to cut the hairspring. Then the hairspring slides away from the forming plate 2 along with the sliding frame 31.

[0031] Referring to Figure 2, a lifting cylinder 11 is provided on the frame 1. The lifting cylinder 11 is vertically arranged, and its piston rod is connected to the forming plate 2. In use, the lifting cylinder 11 drives the forming plate 2 to move closer to the cutting blade 42 and the forming rod 331, thereby improving the convenience of cutting and forming the hairspring on the forming plate 2.

[0032] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
