[0002] Eyeglass frames are an important part of eyeglasses. They not only support the lenses but also have a significant impact on the wearer's appearance. The specific structure of eyeglass frames includes the lens rim, bridge, and temples.

[0003] In the process of processing eyeglass frames, the bridge section of the frame is connected to the lens rim via a connector. Typically, a forming mold is used to bend the bridge material, and then a grooving device is used to create slots in it. These slots can be connected to the lens rim via the connector. However, existing processing equipment requires step-by-step processing of the bridge material, making it impossible to perform bending and grooving actions in a unified and continuous manner, which is detrimental to improving the processing efficiency of the bridge. To address the aforementioned technical deficiencies of the existing technology, a processing device for forming and grooving the bridge of eyeglass frames is proposed to solve the above-mentioned technical problems.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments:

[0023] First Embodiment

[0024] Please see Figure 1-5 A processing device for forming and grooving the bridge of eyeglass frames includes a base plate 1, a gantry frame 2 fixed on the base plate 1, a cylinder 3 fixed on the top of the gantry frame 2, a guide frame 4 fixed on the base plate 1, a horizontal clamping assembly installed inside the guide frame 4, a lifting frame 6 above the guide frame 4, a sliding frame 9 vertically slidably mounted on the lifting frame 6, a vertical spring III 21 fixed between the sliding frame 9 and the lifting frame 6, an upper mold 20 slidably mounted on the lifting frame 6, and a corresponding component installed inside the lifting frame 6. A push-drive assembly is fixed between the lower mold 12, the sliding frame 9, and the telescopic end of the cylinder 3. An extension frame 15 is installed on the push-drive assembly. Two symmetrically arranged guide covers 10 are fixed on the lifting frame 6. A limiting block 7 vertically corresponding to the lower mold 12 is installed inside the guide cover 10. A top plate 24 vertically corresponding to the extension frame 15 is provided above the guide cover 10. A drill rod 27 extending into the limiting block 7 is rotatably installed on the top plate 24. A drive assembly for driving the drill rod 27 to rotate is installed on the guide cover 10.

[0025] When processing the nose bridge material of eyeglasses using this device, the nose bridge material is placed inside the guide frame 4, and the nose bridge material is initially limited by the horizontal clamping assembly. The upper mold 20 is moved down by the lifting frame 6, and the nose bridge material is bent and formed during the extrusion process of the upper mold 20 and the lower mold 12.

[0026] Specifically, the pushing transmission assembly includes a lifting column 14 fixed to the telescopic end of the cylinder 3. A sleeve 8 fixed to the sliding frame 9 is slidably sleeved on the lifting column 14. An extension frame 15 is fixed on the lifting column 14 and slidably connected to the sleeve 8. A vertical spring I16 is fixed between the lifting column 14 and the sleeve 8. A connecting column 22 that slides through the lifting frame 6 is fixed on the upper mold 20. The top of the connecting column 22 is vertically aligned with the sliding frame 9. A vertical spring III21 is fixed between the sliding frame 9 and the lifting frame 6.

[0027] The cylinder 3 drives the lifting column 14 to move vertically downward. The lifting column 14 drives the sleeve 8 and the sliding frame 9 to move vertically downward through the vertical spring I16. The sliding frame 9 pushes the connecting column 22 to move vertically downward, thereby realizing the downward movement of the upper mold 20 and bending the nose bridge material of the eyeglass frame.

[0028] In addition, the drive assembly of this device includes a vertical tube 19 that slides vertically through the guide cover 10, a rotating sleeve 18 that is rotatably mounted on the vertical tube 19, a motor 23 that is fixed on the vertical tube 19, a main gear 25 that is coaxially fixed on the output shaft of the motor 23, a secondary gear 26 that meshes with the main gear 25 that is fixedly sleeved on the rotating sleeve 18, a drill rod 27 that slides through the rotating sleeve 18, a retaining strip 28 that is fixed on the drill rod 27 and slidably embedded in the inner wall of the rotating sleeve 18, and a support spring 29 that is fixed between the top plate 24 and the guide cover 10.

[0029] With the above settings, after the upper mold 20 applies pressure and bends the nose bridge material of the eyeglass frame, the lifting column 14 moves vertically downward relative to the sleeve 8. At this time, the extension frame 15 pushes against the top plate 24. The top plate 24 then drives the rotating drill rod 27 to move downward and open a hole in the nose bridge material of the eyeglass frame. The above actions realize the integrated and continuous bending and grooving of the nose bridge material of the eyeglass frame, which greatly improves the processing efficiency of the nose bridge material of the eyeglass frame.

[0030] The motor 23 drives the main gear 25 to rotate, the main gear 25 drives the auxiliary gear 26 to rotate, the auxiliary gear 26 drives the rotating sleeve 18 to rotate, and the rotating sleeve 18 drives the drill rod 27 to rotate through the clamping strip 28.

[0031] Second Embodiment

[0032] Please see Figure 1-5Based on the first embodiment, a clearance hole 13 corresponding vertically to the drill rod 27 is provided on the lower mold 12. The lower end of the vertical tube 19 is fixed to the limiting block 7, and a vertical spring II 17 is fixed between the limiting block 7 and the guide cover 10. During the process of drilling the hole groove in the nose bridge material of the eyeglass frame, the drill rod 27 will penetrate through the nose bridge material and extend into the clearance hole 13. The clearance hole 13 plays a protective role for the drill rod 27, preventing the drill rod 27 from being obstructed by the lower mold 12.

[0033] During the downward movement of the guide frame 4, the limiting block 7 first contacts and presses against the nose bridge material of the eyeglass frame, thereby vertically clamping and fixing the nose bridge material. This ensures the stability of the subsequent bending and grooving process of the nose bridge material and effectively improves the processing quality of the nose bridge material.

[0034] In addition, the horizontal clamping assembly includes a trapezoidal clamping block 11 that is horizontally slidably mounted on the guide frame 4, and a push spring 5 is fixed between the trapezoidal clamping block 11 and the guide frame 4. The nose bridge material of the eyeglass frame is installed inside the guide frame 4. By pushing the nose bridge material vertically downward, the end of the nose bridge material pushes against the inclined surface of the trapezoidal clamping block 11, and the two trapezoidal clamping blocks 11 move away from each other. Finally, under the pushing action of the push spring 5, the trapezoidal clamping block 11 achieves the effect of horizontally clamping the end of the nose bridge material. The initial limiting operation of the nose bridge material is simple and quick.

[0035] In summary, this utility model, by setting the lifting frame 6 to move downward, allows the limiting pressure block 7 to first press and limit the nose bridge material of the eyeglass frame. Then, the upper mold 20 moves downward and presses and shapes the nose bridge material of the eyeglass frame. After that, the extension frame 15 pushes against the top plate 24, and the top plate 24 drives the rotating drill rod 27 to move downward and open a hole and groove in the nose bridge material of the eyeglass frame for connection with the lens ring. This realizes the continuous operation of limiting, bending and shaping and grooving of the nose bridge material of the eyeglass frame, which greatly reduces the workload of operating the above processes step by step and significantly improves the processing efficiency of the nose bridge material of the eyeglass frame.
