Description

TECHNICAL FIELD

[0001] The utility model relates to punch forming technical field, especially a kind of continuous punch drawing die. BACKGROUND

[0002] As a key component in precision optical equipment, the manufacturing process of laser adjustment ring has long relied on computer numerical control (CNC) machining technology. CNC machining controls the movement trajectory of cutting tools through digital programs, enabling the formation of complex geometric shapes and high-precision size control on metal blanks, such as the thread structure, positioning groove, and micron-level tolerance requirements of the adjustment ring. However, with the increasing demand for production efficiency, cost control, and resource intensification in the industrial field, the limitations of traditional CNC machining in the manufacturing of such parts have become increasingly apparent, particularly in the following aspects:

[0003] Processing efficiency and production cycle bottleneck, CNC machining requires removing excess material through layer-by-layer cutting to form the target structure. For parts like the laser adjustment ring, which has multiple toothed meshing surfaces or irregular profiles, the tool path is complex and the processing time for a single piece is significantly long. Additionally, equipment changeover and clamp adjustment between complex processes further prolong the production cycle.

[0004] Low material utilization and cost pressure, laser adjustment rings are typically made of high-strength metal materials such as stainless steel and titanium alloy. The "subtractive manufacturing" nature of CNC technology results in a material utilization rate of less than 50%. A large amount of metal is wasted in the form of debris. At the same time, the high energy consumption of CNC equipment, frequent tool wear, and maintenance costs further exacerbate the overall cost burden.

[0005] Surface integrity defects and secondary processing dependence, mechanical interaction between the tool and the workpiece during the cutting process can generate microscopic burrs, stress concentration, and work-hardening layers on the surface of the adjustment ring, directly affecting the assembly precision and long-term stability of optical components. To eliminate such defects, CNC-formed adjustment rings often require additional post-processing procedures such as sandblasting and electrolytic polishing, resulting in a longer process flow and fluctuating yield.

[0006] Equipment and technical threshold limitations, high-precision CNC machine tools are expensive to purchase and require high programming skills and process experience from operators. Small and medium-sized manufacturers often face development difficulties due to insufficient funds and talent reserves when upgrading technology or expanding production capacity.

[0007] In summary, the limitations of the existing process in terms of efficiency and cost are increasingly apparent, and need to be addressed. SUMMARY

[0032] The utility model provides a kind of laser adjusting ring 1.

[0033] In the embodiments of the utility model, as shown in Figure 2 The laser adjusting ring 1 is integrally stamped and stretch-formed, which replaces the CNC process of the prior art, and has significant advantages in simplifying process and saving cost.

[0034] In some embodiments of the utility model, the material of the tube body 11 and the side ring 12 is preferably limited to stainless steel 3042B to facilitate continuous stretching to achieve standard dimensions.

[0035] Specifically, in order to further stabilize the toughness and strength of the laser adjusting ring 1, the surface hardness HV of the tube body 11 and the side ring 12 is limited to 150-170.

[0036] In some embodiments of the utility model, the concentricity of the tube body 11 and the side ring 12 is limited to less than 0.02 mm, the perpendicularity is limited to less than 0.02 mm, the flatness is limited to less than 0.03 mm, and the inner diameter is limited to less than 0.02 mm.

[0037] This utility model also proposes a continuous stamping and stretching die 2, such as Figure 1 As shown, the continuous stamping and stretching die 2 includes a lower die 21 and an upper die 22. The upper die 22 is movably disposed above the lower die 21, and a template is provided on the lower wall of the upper die 22. The template includes a punching template 221, a punching and stretching template 222, and a cutting template 223, which are used for punching, stamping, stretching, and cutting the original part to manufacture the aforementioned laser adjustment ring 1. When in use, the movable upper die 22 moves up and down in a direction perpendicular to the lower die 21, and performs corresponding punching, punching and stretching, and cutting actions when it descends to a predetermined position. The structure of the laser adjustment ring 1 manufactured by the continuous stamping and stretching die 2 is as described in the above embodiment. Since this continuous stamping and stretching die 2 adopts all the technical solutions of all the embodiments of the laser adjustment ring 1 described above, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] In some embodiments of this utility model, the punching template 221 includes a first punching die 2211 and a second punching die 2212. The function of the punching template 221 is to perform basic punching on the original part to form a part for stamping. The first punching die 2211 and the second punching die 2212 are used to punch the original part from the side to form a circular piece in the middle, and subsequent steps are performed on the retained circular piece.

[0039] Specifically, in order to keep the disc smoothly on the original part, when the centers of the cutting shapes of the first die 2211 and the second die 2212 overlap, there is no overlapping part between the first die 2211 and the second die 2212. The first die 2211 and the second die 2212 without overlapping part can form a connecting structure around the disc. The connecting structure prevents the disc from detaching from the original part, allowing it to enter the subsequent process flow.

[0040] In some embodiments of this utility model, the stamping and stretching template 222 includes a first stamping die 2221 for stamping discs to form a tube body 11, a second stamping die 2222 for stamping discs to form a side ring 12, and a stretching die 2223 for stretching the tube body 11 and reducing its diameter.

[0041] Specifically, the stamping and stretching template 222 is set in the order of first stamping die 2221, second stamping die 2222, and stretching die 2223. The first stamping die 2221 stamps the circular piece into a tube 11, and then the second stamping die 2222 stamps the edge of the tube 11 into a side ring 12. Finally, the diameter of the tube 11 is reduced by the stretching die 2223, thus realizing the basic forming of the laser adjustment ring 1.

[0042] In some embodiments of this utility model, the cutting template 223 includes a first cutting mold 2231 for cutting the bottom wall of the tube 11 to form a through-hole and a second cutting mold 2232 for separating the tube 11 and the side ring 12 from the disc to form the finished laser adjustment ring 1. The first cutting mold 2231 cuts open the bottom wall of the tube 11, so that both ends of the laser adjustment ring 1 are open. In addition, the second cutting mold 2232 cuts the required tube 11 and side ring 12, so that they are separated from the original part to finally form the laser adjustment ring 1.

[0043] The following content serves as a detailed explanation of the working principle of the continuous stamping and drawing die 2, namely the manufacturing process of the laser adjustment ring 1: Please refer to... Figure 2 For reference in understanding the structure of the laser adjustment ring 1 in this utility model, the laser adjustment ring 1 includes a tube body 11, with a side ring 12 extending outward from the end of the tube body 11. The tube body 11 and the side ring 12 are integrally stamped and stretched. The stamping and stretching is specifically achieved by a continuous stamping and stretching die 2. Please refer to [reference needed]. Figure 1 The working steps of the continuous stamping and drawing die 2 are explained below. Specifically, the continuous stamping and drawing die 2 includes a punching die 221 for punching, a stamping and drawing die 222 for stamping and drawing, and a cutting die 223 for cutting. The punching die 221 requires two punching steps. See [reference needed] for details. Figure 3 and Figure 4 The blanking shape leaves a circular sheet structure in the middle for stamping. Then, the stamping and stretching template 222 stamps and stretches the circular sheet structure to form the tube body 11 and the side ring 12 formed on the edge of the tube body 11. At the same time, the tube body 11 is stretched to reduce its diameter to meet industrial production standards. Finally, the cutting template 223 cuts open the bottom wall of the tube body 11, so that both ends of the laser adjustment ring 1 are in an open state. Then, the laser adjustment ring 1 is cut from the original part to obtain the final product. It should be noted that... In actual processing, the shapes of the punches of the first punching die 2211, the second punching die 2212, the first stamping die 2221, the second stamping die 2222, the stretching die 2223, the first cutting die 2231, and the second cutting die 2232 can be changed according to the actual manufacturing process or according to the different sheet materials. Of course, the specific dimensions and stretching dimensions can also be adjusted according to the final product to achieve the stamping and stretching of the sheet material into a tube body 11 and a side ring 12 located at the upper end of the tube body 11.

[0044] Specifically, the laser adjustment ring 1 formed by stamping and stretching through the above steps has good structural stability, good resistance to structural stress, and high processing efficiency. This utility model has good performance in terms of process efficiency and industrial cost.

[0045] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, as described in the present application specification and drawings, is included in the patent protection scope of the present application.
