Description

Technical Field

[0001] This utility model relates to the field of flange forging technology, and in particular to a flange forging. Background Technology

[0002] Forged flanges are flanges manufactured through forging processes. They are mechanical components used to connect pipes, valves, pumps, and other equipment. Flanges typically have a circular, disc-shaped structure with perforations along the edges for bolting to other equipment, thus achieving a sealing and secure connection. Forging is a processing method that uses pressure to plastically deform metal. Forgings generally possess better mechanical properties, pressure resistance, and corrosion resistance. Compared to castings, forgings have a denser internal molecular structure and higher strength.

[0003] Currently, existing flange forgings, due to the fact that the upper die holder and upper die core are usually an integral structure, and the lower die holder and lower die core are also an integral structure, often lead to limitations in the use of the entire mold when any component is damaged. Furthermore, it is difficult to easily disassemble, repair, or replace the damaged part, increasing maintenance and replacement costs. At the same time, the upper die holder, upper die core, lower die holder, and lower die core in flange forging molds lack effective guiding and limiting structures and buffering mechanisms when used together, resulting in poor stability of the flange forgings during use. Therefore, existing flange forgings may have limitations such as unstable use and inconvenient maintenance in certain situations.

[0004] Based on this, we propose a flange forging to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a flange forging that can solve the problems of existing flange forging molds, such as the inconvenience of disassembly, repair or replacement when the components are damaged due to the integrated structure of the upper and lower mold bases, and the poor stability caused by the lack of guide and limit structures and buffer mechanisms.

[0007] To solve the above technical problems, this utility model provides a flange forging, which adopts the following technical solution: it includes a support plate frame, two sets of guide components are installed on the inner side of the support plate frame, and a forging mold is also provided between the two sets of guide components. The forging mold includes a support component, and a forging stamping part is also provided on the top of the support component.

[0008] The forging stamping part includes an upper die base, an upper die core connected to the bottom of the upper die base, a lower die core provided at the bottom of the upper die core, and guide slide rods connected to the top four corners of the lower die core;

[0009] Two sets of fixing plates are installed on the inner side of the support plate frame. A hydraulic cylinder is installed on the top of each of the two sets of fixing plates. An embedded groove is also installed on the bottom of the support plate frame.

[0010] Optionally, the four sets of guide slide rods are all in sliding fit with the four corners of the upper mold base and the upper mold core.

[0011] Optionally, two sets of guide slides are installed inside the upper mold base, and the guide slides are fixedly connected to the output end of the hydraulic cylinder. Multiple sets of air springs are also connected between the upper mold base and the upper mold core.

[0012] Optionally, a stamping plate body is installed at the bottom of the upper die core, and a stamping plate groove is provided through the middle of the lower die core. The stamping plate groove matches the structure of the stamping plate body, and the stamping plate groove and the stamping plate body are in a transition fit.

[0013] Optionally, the support component includes a lower mold base, the bottom of which is fitted with an inner plate that matches the inner groove structure.

[0014] Optionally, the guide assembly includes a guide cover, the guide cover having a guide groove in the middle, the guide groove matching the guide slide plate structure, and the guide groove and the guide slide plate being in sliding fit.

[0015] In summary, this utility model has at least one of the following beneficial effects: The forging stamping part in this solution is composed of components such as an upper die base, an upper die core, a lower die core, and guide slide rods. Since the guide slide rods are slidably fitted with the four corners of the upper die base and the upper die core, they can stably limit and connect the upper die base and the upper die core to the top of the lower die core. At the same time, the lower die core plays a guiding and limiting role on the four corners of the upper die base and the upper die core, preventing them from shaking or deviating during the stamping process. By installing multiple sets of air springs between the upper die base and the upper die core, the air springs utilize sealed air cavities. When the air is compressed, the pressure inside the cavity increases and generates elastic force, which can effectively resist external compression. As can be seen from the above, the air springs can provide a smooth elastic response between the upper die base and the upper die core, which can significantly reduce the vibration or impact generated by the upper die base and the upper die core during the flange stamping and forging process, thereby further improving the accuracy and stability of stamping and forging.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Refer to Figures 1 to 6This utility model provides an embodiment of a flange forging, including a support plate frame 1. Two sets of guide components 2 are installed on the inner side of the support plate frame 1. A forging mold 3 is also provided between the two sets of guide components 2. The forging mold 3 includes a support component 4. A forging stamping part 5 is also provided on the top of the support component 4. The forging stamping part 5 includes an upper die base 6. An upper die core 7 is connected to the bottom of the upper die base 6. A lower die core 8 is provided at the bottom of the upper die core 7. Guide slide rods 9 are connected to the four corners of the top of the lower die core 8. Two sets of fixing plates 10 are installed on the inner side of the support plate frame 1. Each of the two sets of fixing plates 10 has a guide slide rod 9 installed on its top. The system includes a hydraulic cylinder 11 and an embedded groove 12 at the bottom of the support plate frame 1. This solution uses two sets of guide components 2 installed inside the support plate frame 1. These guide components 2 are matched with the guide slide plate 13 through the guide groove 20 and the guide slide plate 13 through the sliding fit between the guide groove 20 and the guide slide plate 13. This design allows the forged stamping part 5 installed on the top of the support component 4 to be connected and fixed between the output ends of the two sets of hydraulic cylinders 11. At the same time, it can also guide and limit one side of the forged stamping part 5 that is adjusted for lifting, thereby improving the stability of the forged stamping part 5 in the flange stamping and forging process.

[0026] The four sets of guide slide rods 9 are all in sliding fit with the four corners of the upper die base 6 and the upper die core 7. This sliding fit design allows the upper die base 6 and the upper die core 7 to be fixedly connected to the top of the lower die core 8. Simultaneously, the lower die core 8 also guides and limits the four corners of the upper die base 6 and the upper die core 7 during stamping and forging, preventing them from shaking or shifting during the stamping and forging process. Two sets of guide slide plates 13 are installed inside the upper die base 6, and these plates are fixedly connected to the output end of the hydraulic cylinder 11. Multiple sets of air springs 14 are also connected between the upper die base 6 and the upper die core 7. These additional air springs 14 further enhance the stability and stability of the upper die base 6 and the upper die core 7. Spring 14, an air spring 14 is a shock absorber in the prior art. The air spring 14 has an internal sealed air cavity. When the air is compressed, the pressure inside the cavity increases, generating elastic force to resist external compression, which can provide a more stable elastic response. It can effectively reduce the vibration or impact force generated by the upper die base 6 and the upper die core 7 on the flange stamping and forging. The bottom of the upper die core 7 is equipped with a stamping plate body 15, and the middle of the lower die core 8 is provided with a stamping plate groove 16. The stamping plate groove 16 and the stamping plate body 15 are structurally matched. The stamping plate groove 16 and the stamping plate body 15 are transition fit. Through the structural design of the transition fit between the stamping plate groove 16 and the stamping plate body 15, the metal parts can be processed by flange stamping and forging.

[0027] The support component 4 includes a lower die base 17, with an inner plate 18 installed at the bottom of the lower die base 17. The inner plate 18 matches the structure of the inner groove 12. By installing the inner plate 18 at the bottom of the lower die base 17, the support component 4 with the forged stamping part 5 installed on the top can be limited and fixed inside the support plate frame 1. The guide component 2 includes a guide cover 19, with a guide groove 20 in the middle of the guide cover 19. The guide groove 20 matches the structure of the guide slide plate 13, and the guide groove 20 and the guide slide plate 13 are in sliding fit. Through the structural design of the sliding fit between the guide groove 20 and the guide slide plate 13, the forged stamping part 5 installed on the top of the support component 4 can be connected and fixed between the output ends of the two sets of hydraulic cylinders 11. At the same time, it can also guide and limit one side of the forged stamping part 5 that is adjusted in height.

[0028] Working principle: This solution uses two sets of guide components 2 installed inside the support plate frame 1. The guide components 2 are matched with the guide slide plate 13 through the guide groove 20 and the guide slide plate 13. The guide groove 20 and the guide slide plate 13 are designed to slide and cooperate with each other. The forged stamping part 5 installed on the top of the support component 4 can be connected and fixed between the output ends of the two sets of hydraulic cylinders 11. At the same time, it can also guide and limit one side of the lifting and adjusting forged stamping part 5, thereby improving the stability of the forged stamping part 5 in the flange stamping and forging.

[0029] The forging stamping part 5 in this solution mainly consists of components such as an upper die base 6, an upper die core 7, a lower die core 8, and a guide slide rod 9. Since the guide slide rod 9 has a sliding fit with the four corners of the upper die base 6 and the upper die core 7, it can limit the connection of the upper die base 6 and the upper die core 7 to the top of the lower die core 8. At the same time, the lower die core 8 can also guide and limit the four corners of the upper die base 6 and the upper die core 7 during stamping and forging, which can prevent the upper die base 6 and the upper die core 7 from shaking or deviating during the stamping and forging process. In conjunction with the multiple sets of air springs 14 installed between the upper die base 6 and the upper die core 7, the air spring 14 is a kind of shock absorber in the prior art. The air spring 14 has an internal sealed air cavity. When the air is compressed, the pressure inside the cavity increases, generating elastic force to resist external compression, which can provide a more stable elastic response and effectively reduce the vibration or impact force generated by the upper die base 6 and the upper die core 7 on the flange stamping and forging.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
