Description

Technical Field

[0001] This utility model relates to the technical field of metal forging, and in particular to a forging system for forming heat dissipation baffles. Background Technology

[0002] In the field of metal processing, forging is an important forming method. It involves applying pressure to a metal blank to induce plastic deformation, thereby obtaining parts of the desired shape and size. As various industries continue to increase their requirements for the performance and precision of metal parts, forging technology is also constantly developing and innovating.

[0003] For the production of complex-shaped forgings, traditional one-stage forging processes face numerous challenges. In industries such as aerospace and high-end equipment manufacturing, the required metal parts have increasingly complex structures, including numerous ribs, bosses, and other intricate features. When processing such complex forgings using a one-stage forging process, the metal flow within the die is difficult to distribute evenly, easily leading to serious defects such as folds and cracks in the forgings. Simultaneously, during the one-stage forging process, uneven metal flow generates excessive localized impact and friction forces on the forging die cavity, accelerating die wear and significantly shortening the die's service life.

[0004] To address these challenges, pre-forging technology emerged. However, the difficulty of pre-forging lies in how to precisely optimize the die cavity design for forgings of varying complexity. Especially for forgings with complex structures like heat sinks and unevenly distributed protrusions (thick at both ends and thin in the middle), traditional pre-forging die cavity designs are insufficient. This leads to poor compatibility between the billet and the forging die during the subsequent final forging process, resulting in high deformation energy consumption, short die cavity life, and incomplete filling of complex structural areas.

[0005] Furthermore, the specific structural design of the forging die plays a decisive role in the forging efficiency, die life, and forging quality throughout the entire forging process. For complex final forgings, existing forging die structures often cannot meet the demands of efficient and high-quality production. For example, when forming heat dissipation baffles, due to the special structures such as irregularly shaped protrusions and I-shaped protrusions on the upper and lower sides, ordinary forging dies cannot accurately guide the metal flow, resulting in poor dimensional accuracy and low surface quality of the formed protrusions, which cannot meet the installation and usage requirements of the heat dissipation cavity.

[0006] In summary, in the current field of metal forging, the optimized design of pre-forging die cavity for complex forgings and the innovative optimization of forging die structure remain important technical problems that urgently need to be solved. This utility model is developed based on this background. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] This utility model provides a forging system for forming a heat dissipation baffle, including a pre-pressing die and a forging die.

[0009] The pre-pressing mold is equipped with an upper pre-pressing mold and a lower pre-pressing mold. Pre-pressing mold cavities are opened at corresponding positions of the upper and lower pre-pressing molds to perform pre-pressing operations on the metal parts and form pre-pressed blanks.

[0010] The forging die includes a concave die plate and a lower die base plate fixedly connected to each other, and a convex die plate and an upper die base fixedly connected to each other; the lower die base plate is installed on the working platform of the forging equipment, the concave die plate is provided with a forging die cavity; the upper die base is installed on the hammer of the forging equipment, and the convex die plate is provided with a forging protrusion at the part corresponding to the forging die cavity. The forging protrusion and the forging die cavity cooperate to forge the pre-pressed billet into shape.

[0011] The pre-compression die cavity is provided with a polygonal groove with a polygonal cross-section, and the depth of the polygonal grooves at both ends along the axial direction of the pre-compression blank is greater than the depth of the middle polygonal groove, thereby forming a dumbbell-shaped pre-compression blank.

[0012] Furthermore, the bottom of the forging die cavity is provided with an I-shaped groove for forming the I-shaped protrusion on the lower side of the baffle.

[0013] Furthermore: Lower mold protrusions are provided on the inner walls of both ends of the I-shaped groove to form the lower mounting grooves at both ends of the I-shaped protrusion.

[0014] Furthermore: On both sides of the I-shaped groove, there are lower mold notches for forming the lower mold bosses on both sides of the I-shaped protrusion.

[0015] Furthermore: the forged protrusion is provided with an irregular groove for forming an irregular protrusion on the upper side of the baffle.

[0016] Furthermore: Upper mold protrusions are provided on the inner walls at both ends of the irregular groove to form the upper mounting grooves at both ends of the irregular protrusion.

[0017] Furthermore: On both sides of the irregular groove, there are upper mold notches for forming the upper mold bosses on both sides of the irregular convex pillar.

[0018] Furthermore, on both sides of the irregular groove, there are transverse deep grooves for forming transverse stiffeners on both sides of the irregular convex column.

[0019] Furthermore, a D-shaped shallow groove is provided on the top of the forged protrusion to form a short protrusion on the upper side of the baffle.

[0020] Furthermore, it also includes an ejector assembly, which is equipped with an ejector plate and an ejector rod. An ejector through hole is opened at the bottom of the forging die cavity corresponding to the bottom of the die plate and the concave die plate. One end of the ejector rod extends through the ejector through hole into the die cavity, and the other end abuts against the ejector plate. The ejector plate drives the ejector rod to eject the forging.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Optimized pre-forging process and improved billet quality: This invention sets the cross-section of the pre-pressing die cavity as a polygon, extending along the axial direction of the pre-pressing billet, enabling the formation of polygonal pre-pressing billets. Compared to traditionally shaped billets, this allows for better extension and stronger plastic deformation, laying the foundation for obtaining forgings with precise shapes and dimensions. Simultaneously, by setting the depth of the polygonal grooves at both ends of the pre-pressing die cavity to be greater than the depth in the middle, a dumbbell-shaped pre-pressing billet is formed. This shape matches the thickness distribution characteristics of the protrusions on both sides of the heat dissipation baffle, allowing the billet to better fit the forging die during the final forging stage, further optimizing the forging process. This not only reduces the deformation energy consumption required for final forging—actual tests show a 20%-30% reduction—but also effectively extends the service life of the final forging die cavity. Simulation and actual production verification show that the service life of the final forging die cavity can be extended by 30%-40%, further ensuring the filling integrity of complex structural parts such as ribs and bosses, significantly improving the quality of forgings.

[0023] 2. Precise Forming of Complex Structures to Meet Installation Requirements: In terms of forging die structure design, an I-shaped groove is set at the bottom of the forging die cavity to precisely form the I-shaped protrusion on the lower side of the baffle, meeting the installation requirements of the baffle in the external heat dissipation cavity. Lower die protrusions are set at both ends of the I-shaped groove to form the lower mounting grooves at both ends of the I-shaped protrusion, facilitating better insertion of the I-shaped protrusion into the heat dissipation cavity mounting part. Similarly, lower die notches are set on both sides of the I-shaped groove to form lower die bosses on both sides of the I-shaped protrusion, further enhancing installation stability. Irregularly shaped grooves are set at the forging protrusion to form irregularly shaped protrusions on the upper side of the baffle, meeting installation requirements. Upper die protrusions are set at both ends of the irregularly shaped groove to form the upper mounting grooves at both ends of the irregularly shaped protrusion, facilitating the installation of the irregularly shaped protrusion. Upper die notches and transverse deep grooves are set on both sides of the irregularly shaped groove to form upper die bosses and transverse stiffeners on both sides of the irregularly shaped protrusion, meeting installation requirements and enhancing the structural strength of the irregularly shaped protrusion. A D-shaped shallow groove is set on the top of the forged protrusion, which can form the short protrusion on the upper side of the baffle, meeting the diverse installation requirements of the heat dissipation cavity. Through these precise mold structure designs, the complex structure of the heat dissipation baffle is accurately formed, greatly improving the compatibility between the forging and the heat dissipation cavity.

[0024] In summary, this utility model uses a pre-pressing mold to form polygonal and dumbbell-shaped blanks, and a forging mold to accurately form complex structures, thereby optimizing the forging process, reducing energy consumption, extending the die cavity life, ensuring filling, adapting to installation, and increasing strength and stability.

Detailed Implementation

[0036] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please see Figures 1 to 7 In this embodiment of the invention, a forging system for forming a heat dissipation baffle includes a pre-pressing mold 10 and a forging mold 20.

[0038] The pre-pressing mold 10 is provided with a pre-pressing upper mold 11 and a pre-pressing lower mold 12. Pre-pressing mold cavities 13 are respectively opened at corresponding positions of the pre-pressing upper mold 11 and the pre-pressing lower mold 12, so as to perform pre-pressing operation on the metal part and form a pre-pressed blank 40.

[0039] The forging die 20 includes a concave die plate 33 and a lower die base plate 30 fixedly connected to each other, and a convex die plate 22 and an upper die base 21 fixedly connected to each other; the lower die base plate 30 is installed on the working platform of the forging equipment, the concave die plate 33 is provided with a forging die cavity 34; the upper die base 21 is installed on the hammer of the forging equipment, and the convex die plate 22 is provided with a forging protrusion 23 at the part corresponding to the forging die cavity 34. The forging protrusion 23 and the forging die cavity 34 cooperate to forge the pre-pressed billet 40.

[0040] The pre-pressing die cavity 13 is provided with a polygonal groove 14 with a polygonal cross section. The depth of the polygonal groove 14 at both ends along the axial direction of the pre-pressing blank 40 is greater than the depth of the middle polygonal groove 14, thereby forming a dumbbell-shaped pre-pressing blank 40.

[0041] Specifically, in the forging process of metals, it is often difficult to form complex forgings in a single operation. Forcing a single forging process can easily lead to defects such as folds and cracks in the forgings, and can also affect the service life of the forging die cavity. Therefore, the pre-forging process, an intermediate deformation step in the forging process, has emerged. Pre-forging is a crucial transitional step connecting billet preparation and final forging in the forging process. Its core function is to control the metal flow to achieve a material distribution state in the billet that closely resembles the final forging shape. This step employs a specially designed die cavity structure with a larger fillet radius (typically increased by 2-5 mm) and forging draft angle than the final forging die cavity to reduce metal flow resistance. However, the challenge of the pre-forging process lies in optimizing the die cavity design, especially for complex forgings, where the special structure of the die cavity warrants further research.

[0042] This invention allows the pre-pressing die cavity 13 to have a polygonal cross-section, extending along the axial direction of the metal part, so that the entire pre-pressing blank 40 can be formed into a polygonal shape. For example, the pre-pressing die cavity 13, which is formed by the cooperation of the pre-pressing upper die 11 and the pre-pressing lower die 12, has a hexagonal cross-section, so that a pre-pressing blank 40 with the same hexagonal cross-section can be pre-pressed. This allows it to be better extended and generate stronger plastic deformation during the final forging in the subsequent forging die 20, thereby obtaining the required shape and size.

[0043] Secondly, since the shape distribution of the protrusions on both sides of the heat dissipation baffle 41 is uneven, with the thickness at both ends of the protrusions being greater and the thickness in the middle being thinner, the depth of the polygonal grooves 14 at both ends of the pre-pressing die cavity 13 can be set to be greater than the depth of the polygonal groove 14 in the middle, thereby forming a dumbbell shape, that is, a shape with larger ends and smaller middle, so that the pre-pressed billet 40 can be better adapted to the forging die 20 in the subsequent final forging process, further optimizing the forging process, reducing the deformation energy consumption required for final forging, extending the service life of the final forging die cavity, and ensuring the filling integrity of complex structural parts (such as ribs and bosses).

[0044] Furthermore, due to the relatively complex shape and structure of the final forging, the specific structural design of the forging die 20 also needs to be optimized. How to optimize this design to improve forging efficiency, extend the service life of the forging die 20, and enhance the forming quality of the forging is a technical issue worthy of study. The polygonal groove 14 of the pre-compression die cavity 13 has a greater depth at both ends than in the middle along the axial direction of the pre-compression blank 40, causing the formed blank to exhibit a dumbbell shape with larger diameters at both ends and a smaller diameter in the middle, similar to the contour structure of a barbell.

[0045] like Figures 3 to 5 As shown, preferably, the bottom of the forging die cavity 34 is provided with an I-shaped groove 35 for forming the I-shaped protrusion 47 on the lower side of the baffle 41.

[0046] Specifically, according to the installation and use requirements of the baffle 41 of the external heat dissipation cavity, the lower side of the baffle 41 needs to be provided with an I-shaped protrusion. Therefore, an I-shaped groove can be provided in the forging die cavity 34 of the concave die 33. The I-shaped groove is used to restrict and guide the plastic flow of the pre-pressed billet 40 during the forging process, thereby forming the corresponding I-shaped protrusion 47.

[0047] like Figures 3 to 5 As shown, preferably, lower mold protrusions are provided on the inner walls of both ends of the I-shaped groove to form the lower mounting grooves 48 at both ends of the I-shaped protrusion 47.

[0048] Specifically, in order to better engage the I-shaped protrusion 47 with the mounting portion of the external heat dissipation cavity when it is installed, it is preferable to provide lower mounting grooves 48 at both ends of the I-shaped protrusion 47. Therefore, lower die protrusions can be provided at both ends of the forging die cavity 34, and the lower die protrusions can be used to restrict and guide the plastic flow of the pre-pressed billet 40 during the forging process, thereby forming the corresponding lower mounting grooves 48.

[0049] like Figures 3 to 5 As shown, preferably, a lower die notch 37 is provided on both sides of the I-shaped groove to form the lower die bosses on both sides of the I-shaped protrusion 47.

[0050] Specifically, on both sides of the I-shaped protrusion 47, multiple lower die protrusions are provided according to the installation requirements of the external heat dissipation cavity. Therefore, multiple corresponding lower die notches 37 can be set on both sides of the I-shaped groove of the forging die cavity 34, so that the corresponding lower die protrusions on both sides of the I-shaped protrusion 47 can be formed during the forging process.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, preferably, the forged protrusion 23 is provided with an irregular groove 25 for forming an irregular protrusion 43 on the upper side of the baffle 41.

[0052] Specifically, according to the installation requirements of the external heat dissipation cavity for the baffle 41, the upper side of the baffle 41 needs to be provided with irregular protrusions 43. Therefore, irregular grooves 25 can be provided at the forging protrusions 23 of the protrusion plate 22. The irregular grooves 25 are used to restrict and guide the plastic flow of the pre-pressed blank 40 during the forging process, thereby forming the corresponding irregular protrusions 43.

[0053] like Figure 3 , Figure 6 and Figure 7 As shown, preferably, upper mold protrusions are provided on the inner walls of both ends of the irregular groove 25 to form the upper mounting grooves 44 at both ends of the irregular protrusion 43.

[0054] Specifically, in order to better engage the irregularly shaped protrusion 43 with the mounting portion of the heat dissipation cavity when it is installed, preferably, upper mounting grooves 44 are provided at both ends of the irregularly shaped protrusion 43. Therefore, upper die protrusions can be provided at both ends of the irregularly shaped groove 25, and the upper die protrusions can be used to restrict and guide the plastic flow of the pre-pressed blank 40 during the forging process, thereby forming the corresponding upper mounting grooves 44.

[0055] like Figure 3 , Figure 6 and Figure 7 As shown, preferably, upper mold notches 27 are provided on both sides of the irregular groove 25 to form the upper mold bosses on both sides of the irregular protrusion 43.

[0056] Specifically, on both sides of the irregular protrusion 43, multiple upper die protrusions are provided according to the installation requirements of the external heat dissipation cavity. Therefore, multiple corresponding upper die notches 27 can be set on both sides of the irregular groove 25 of the forging protrusion 23, so that the corresponding upper die protrusions on both sides of the irregular protrusion 43 can be formed during the forging process.

[0057] like Figure 3 , Figure 6 and Figure 7 As shown, preferably, transverse deep grooves 28 are provided on both sides of the irregular groove 25 to form transverse stiffeners 46 on both sides of the irregular protrusion 43.

[0058] Specifically, on both sides of the irregular protrusion 43, according to the installation requirements of the external heat dissipation cavity or to enhance the structural strength of the irregular protrusion 43, multiple transverse stiffeners 46 are provided. Therefore, multiple corresponding transverse deep grooves 28 can be provided on both sides of the irregular groove 25 of the forging protrusion 23, so that during the forging process, by restricting the flow of metal to both sides, the corresponding transverse stiffeners 46 on both sides of the irregular protrusion 43 are guided to be formed.

[0059] like Figure 3 , Figure 6 and Figure 7 As shown, preferably, a D-shaped shallow groove 24 is provided on the top of the forging protrusion 23 for forming the short protrusion 42 on the upper side of the baffle 41.

[0060] Specifically, on the upper side of the baffle 41, multiple short protrusions 42 are provided according to the installation requirements of the external heat dissipation cavity. Therefore, multiple corresponding D-shaped shallow grooves 24 can be set on the top of the forging protrusion 23, so that the corresponding short protrusions 42 on the upper side of the baffle 41 can be formed by the cross-sectional contour of the shallow groove during the forging process.

[0061] like Figure 3As shown, preferably, it also includes an ejection assembly, which is provided with an ejection plate and an ejector rod. An ejection through hole 31 is opened at the position of the lower die bottom plate 30 and the concave die plate 33 corresponding to the bottom of the forging die cavity 34. One end of the ejector rod passes through the ejection through hole 31 and extends into the die cavity, while the other end abuts against the ejection plate. The ejector plate drives the ejector rod to eject the forging.

[0062] Specifically, since the pre-pressed billet 40, after being forged by the forging die 20, forms a forging of the corresponding shape, it may become stuck in the forging die cavity 34. Therefore, an ejector assembly can be installed at the lower part of the forging die 20. Using the ejector plate and ejector rod in the prior art, the forging is ejected to ensure smooth demolding. The other end of the ejector rod abuts against the ejector plate, which moves up and down via hydraulic drive or mechanical transmission mechanism (such as the ejector cylinder in the prior art), thereby driving the ejector rod to eject the forging from the forging die cavity 34 and demold it.

[0063] Secondly, similarly, at the corresponding position of the pre-pressing die 12, there are also corresponding ejection through holes 31 and ejector pins to eject the pre-pressed blank 40.

[0064] Additionally, a lower clamping plate 32 can be installed at the waist of the concave template 33 to fix the concave template 33 and improve the overall stability of the concave template 33. The lower die base plate 30 and the concave template 33 can be fixedly connected by bolts; similarly, the upper die base 21 and the convex template 22 can also be fixedly connected by bolts. A lower clamping plate 32 is installed in the middle of the side of the concave template 33, and the lower clamping plate 32 is fastened to the concave template 33 by bolts, improving the stability of the concave template 33 during the forging process.

[0065] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
