Description

Technical Field

[0001] This invention relates to the field of die forging, and more specifically, to a multi-directional die forging mold for precision forgings. Background Technology

[0002] Traditional forging processes such as free forging and unidirectional die forging can only apply pressure from one direction, resulting in limited forming capacity, difficulty in forming irregularly shaped precision forgings with internal holes, lateral bosses, and complex internal cavities, and a tendency to produce flash, requiring large draft angles, low material utilization, large machining allowances, cumbersome processes, and high energy consumption. At the same time, unidirectional deformation can lead to insufficient metal density and discontinuous flow lines, resulting in poor mechanical properties such as strength and fatigue performance of forgings, making it difficult to meet the requirements of high performance, lightweight, and near-net-shape forming of complex precision forgings in aerospace, automotive, and energy equipment fields. Multidirectional die forging, by applying pressure simultaneously in multiple vertical and horizontal directions, allows the metal to flow plastically under triaxial compressive stress, enabling the one-time completion of flash-free precision forming of complex structural parts. This can significantly improve material utilization and production efficiency, reduce costs, and significantly refine the microstructure and improve the comprehensive mechanical properties of forgings. It effectively solves the technical bottlenecks of traditional forging processes in the manufacturing of complex precision forgings and is a key technology for achieving high-quality, high-efficiency, and green manufacturing of high-end precision forgings.

[0003] In the die forging process, the mold needs to be sprayed with a lubricating release agent to protect the internal forming cavity before die forging. However, the existing spraying method requires the upper and lower molds to be separated and the internal forming cavity to be sprayed manually. This makes it difficult to ensure sufficient time for the agent to fully adhere and penetrate during the process of spraying the upper and lower molds separately. Furthermore, the second spraying after the agent has solidified results in low spraying efficiency. In addition, the inconsistent speed and rhythm of manual operation make it difficult to ensure sufficient contact on the surface of each forming cavity, making it difficult to achieve an effective protective effect. Summary of the Invention

[0004] This invention provides a multi-directional forging die for precision forgings, which solves the technical problems in related technologies where manual spraying is not only inefficient but also makes it difficult to ensure the uniformity of the spraying, and easily leads to localized insufficient spraying.

[0005] The present invention provides a precision forging multi-directional die forging mold, including a machine body, a bottom mold fixedly mounted on the machine tool of the machine body, an upper mold provided above the bottom mold, and a demolding part provided on the bottom mold;

[0006] The demolding section includes a demolding assembly and a recycling assembly. The demolding assembly is located inside the bottom mold, and the recycling assembly is located at the bottom of the bottom mold. The demolding assembly includes a groove formed on the inner bottom wall of the bottom mold, extending to the bottom of the bottom mold. A sliding rod is slidably connected to the inner wall of the groove. The sliding rod has several grooves I inside. A spring I is fixedly connected to the inner top wall of each of the grooves I. A valve block is fixedly connected to the bottom end of each of the springs I. The valve block is cylindrical and matches the inner diameter of the groove I. A cavity is formed inside the sliding rod. The grooves I are connected to the cavity inside the sliding rod. The outer wall of the sliding rod has several grooves II, which are respectively connected to the grooves I. The valve blocks are respectively located at the connection points between the grooves II and the grooves I.

[0007] In a preferred embodiment, a washer is fixedly connected to the bottom outer wall of the slide rod, and a second spring is wound around the outer wall of the slide rod. The bottom end of the second spring is fixedly connected to the top of the washer, and the top end of the second spring is fixedly connected to the bottom of the bottom mold.

[0008] In a preferred embodiment, the inner wall cavity of the slide rod is threaded with a nozzle, and the connection between the slide rod and the nozzle is wrapped with waterproof tape.

[0009] In a preferred embodiment, a bend is rotatably connected to the inner wall of the nozzle, a connecting ring is fixedly connected to the top outer wall of the bend, the connecting ring is rotatably connected to the inner wall of the nozzle, and a flexible hose is fixedly connected to the bottom end of the bend.

[0010] In a preferred embodiment, electric push rods are fixedly connected to both the left and right sides of the machine body, and side molds are fixedly connected to the output ends of both electric push rods.

[0011] In a preferred embodiment, an electric push rod two is fixedly connected to the top of the machine body, and a support plate is fixedly connected to the output end of the electric push rod two. The upper mold is fixedly installed at the bottom of the support plate.

[0012] In a preferred embodiment, a first forming cavity is provided between the bottom mold and the upper mold, and a second forming cavity is provided on the left and right sides of the bottom mold and the upper mold, and the two side molds are respectively adapted to the inner diameter of the second forming cavity.

[0013] In a preferred embodiment, an electric push rod three is fixedly connected to the bottom of the machine body, and a top tube is fixedly connected to the output end of the electric push rod three. A slot is opened on the top tube, and the top end of the top tube contacts the bottom of the washer.

[0014] In a preferred embodiment, the recycling component includes two guide channels formed on the bottom mold, the two guide channels being symmetrically arranged on the left and right sides of the bottom mold, and the two guide channels being located below the second forming cavity.

[0015] In a preferred embodiment, a collection groove is provided on the bottom mold, the collection groove is connected to two guide grooves respectively, and a second flexible hose is fixedly connected to the inner wall of the collection groove, the collection groove and the second flexible hose are connected.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting multiple grooves II, allows the lubricating release agent poured into the slide rod under the action of an external pump to squeeze the valve block inside the multiple grooves I to move upward, and then spray it out through the multiple grooves II to spray the inner wall of the forming cavity I, thereby providing the expected protection for the inner walls of the bottom mold and the upper mold. This spraying method not only isolates the inside of the forming cavity I from air before spraying to prevent the lubricating release agent from leaking out, but also solves the problems of low efficiency and difficulty in ensuring uniform spraying, which easily leads to local insufficient spraying. Moreover, the lubricating release agent can be poured into the forming cavity I from all directions without dead angles, ensuring sufficient time for it to fully adhere and penetrate. The spraying efficiency is high, and it ensures uniform spraying of every part of the inner wall of the mold, maximizing the protection effect, providing a solid guarantee for subsequent die forging operations, effectively extending the service life of the mold, and reducing production costs.

[0018] 2. This invention, by setting up a collection tank, allows for the following process: after spraying the inner wall of the first forming cavity, two electric push rods can be driven to move the two side molds away from each other. At this time, excess lubricating release agent will flow out through the two second forming cavities and be guided into the collection tank through two guide channels. The excess lubricating release agent can then be discharged and collected through the second hose for subsequent reuse. This not only improves the utilization rate of the lubricating release agent and reduces waste, but also conforms to the concepts of environmental protection and economy, further optimizing the entire process of mold protection before die forging.

[0019] 3. By incorporating a sliding rod, after the forging is completed, the two electric push rods are driven to move away from each other while the electric push rod 2 moves the upper mold upward. At this time, the electric push rod 3 moves the sliding rod upward to eject the forging from the mold, achieving rapid demolding, improving production efficiency, and reducing the production cycle of a single forging.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0031] like Figures 1 to 8 As shown, a precision forging multi-directional die includes a machine body 1, a bottom die 101 fixedly mounted on the machine tool of the machine body 1, an upper die 102 provided above the bottom die 101, and a demolding part 2 provided on the bottom die 101.

[0032] The demolding section 2 includes a demolding assembly 21 and a recovery assembly 22. The demolding assembly 21 is located inside the bottom mold 101, and the recovery assembly 22 is located at the bottom of the bottom mold 101. The demolding assembly 21 includes a groove 211 formed on the inner bottom wall of the bottom mold 101. The groove 211 extends to the bottom of the bottom mold 101. A slide rod 212 is slidably connected to the inner wall of the groove 211. A plurality of grooves 213 are formed inside the slide rod 212. A spring 2 is fixedly connected to the inner top wall of each of the grooves 213. 14. A valve block 215 is fixedly connected to the bottom end of several springs 214. The valve block 215 is cylindrical and matches the inner diameter of the groove 213. A cavity is opened inside the slide rod 212. Several grooves 213 are connected to the cavity inside the slide rod 212. Several grooves 216 are opened on the outer wall of the slide rod 212. Several grooves 216 are connected to several grooves 213. Several valve blocks 215 are located at the connection between grooves 216 and grooves 213.

[0033] It should be noted that both groove 1 (213) and groove 2 (216) are cylindrical grooves. These cylindrical grooves provide a regular and suitable movement space for the valve block 215, allowing for smoother up-and-down movement within groove 1 (213). Furthermore, under the action of spring 214, the valve block 215 can tightly conform to the groove wall, effectively preventing leakage of lubricating agents and other substances, ensuring the reliable operation of the one-way valve. In addition, the shape of the cylindrical grooves helps to evenly distribute internal pressure. When lubricating agents are injected into the internal cavity of the slide bar 212 and compress the valve block 215, the cylindrical grooves ensure that the pressure is evenly distributed on the surface of the valve block 215, preventing deformation or damage due to excessive local pressure. This ensures the stability and reliability of the demolding assembly 21 during repeated use, providing strong support for the efficient operation of the entire precision forging multi-directional forging die.

[0034] Existing spraying methods require separating the upper and lower molds and then manually spraying the internal forming cavity. This makes it difficult to ensure sufficient time for the coating to fully adhere and penetrate during the process of spraying the upper and lower molds separately. Furthermore, waiting for the coating to solidify before applying a second coat results in low spraying efficiency.

[0035] In this embodiment, the specific implementation scenario is as follows: The hose 2193 is connected to an external pump. After the lubricating release agent is pumped into the nozzle 219 through the hose 2193, the lubricating release agent fills the cavity of the slide bar 212. At this time, the electric push rod 105 is driven to move the support plate 106 downwards, causing the upper mold 102 to connect with the bottom mold 101. The electric push rods 103 on both sides are driven to move the side molds 104 closer together, causing the two side molds 104 to slide into the molding cavity 101b between the bottom mold 101 and the upper mold 102. At this time, the molding cavity 101a is isolated from the outside. The electric push rods can then be driven. The third 107 drives the top tube 107a to move upward. The top tube 107a has a slot, and the bent tube 2191 is located inside the slot of the top tube 107a. After the top tube 107a contacts the bottom of the washer 217, it drives the slide rod 212 to move upward as a whole, so that multiple grooves 216 are located in the molding cavity 101a. At this time, under the action of the external pump, the lubricating release agent injected into the slide rod 212 will squeeze the valve block 215 inside the multiple grooves 213 to move upward, and spray it out through the multiple grooves 216 to spray the inner wall of the molding cavity 101a, thereby providing the expected protection for the inner wall of the bottom mold 101 and the upper mold 102.

[0036] like Figure 7 and Figure 8 As shown, a washer 217 is fixedly connected to the bottom outer wall of the slide rod 212, and a spring 218 is wound around the outer wall of the slide rod 212. The bottom end of the spring 218 is fixedly connected to the top of the washer 217, and the top end of the spring 218 is fixedly connected to the bottom of the bottom mold 101.

[0037] It should be noted that spring 218 is used to reset the position of slide bar 212, ensuring that all aspects of the die forging process can be closely connected and operate efficiently.

[0038] like Figure 8 As shown, the inner wall cavity of the slide rod 212 is threaded with a nozzle 219, and the connection between the slide rod 212 and the nozzle 219 is wrapped with waterproof tape.

[0039] It should be noted that the waterproof tape can fill any tiny gaps that may exist at threaded joints, preventing the lubricating release agent from seeping out of these gaps. Especially when the lubricating release agent is pumped in under high pressure, the waterproof tape can effectively resist internal pressure, ensuring that the lubricating release agent flows entirely along the predetermined path, preventing waste or affecting the normal operation of other parts of the mold due to leakage.

[0040] like Figure 7As shown, a bend 2191 is rotatably connected to the inner wall of the nozzle 219, a connecting ring 2192 is fixedly connected to the top outer wall of the bend 2191, the connecting ring 2192 is rotatably connected to the inner wall of the nozzle 219, and a hose 2193 is fixedly connected to the bottom end of the bend 2191.

[0041] It should be noted that the bend 2191 and the connecting ring 2192 cooperate with each other to ensure that the bend 2191 can rotate on the inner wall of the nozzle 219, and to ensure that the bend 2191 is inside the groove of the top tube 107a when the top tube 107a moves upward, so as to avoid the bend 2191 affecting the up and down movement of the top tube 107a and ensure the stable operation of the entire spraying system.

[0042] In this embodiment, the specific implementation scenario is as follows: multiple springs 214 cooperate with the valve block 215 so that, under the normal condition of springs 214, the valve block 215 is located at the connection between groove 216 and groove 213, isolating the internal cavity of the slide rod 212 from the external environment. Simultaneously, it acts as a one-way valve, ensuring that the lubricating release agent can only be sprayed out, preventing backflow and guaranteeing the smooth progress of the spraying process and the rational utilization of the lubricating release agent. This further enhances the reliability and stability of the entire mold protection process. The nozzle 219 and the inner wall of the slide bar 212 are connected by threads, which makes the nozzle 219 easy to disassemble, thereby enabling the internal parts of the slide bar 212 to be cleaned and inspected. At the same time, the bent tube 2191 and the connecting ring 2192 cooperate with each other to ensure that the bent tube 2191 can rotate on the inner wall of the nozzle 219. This ensures that when the top tube 107a moves upward, the bent tube 2191 is inside the groove of the top tube 107a, avoiding the bending tube 2191 from affecting the vertical movement of the top tube 107a and ensuring the stable operation of the entire spraying system.

[0043] like Figures 1 to 3 As shown, electric push rods 103 are fixedly connected to the left and right sides of the machine body 1, and side molds 104 are fixedly connected to the output ends of the two electric push rods 103.

[0044] It should be noted that the two electric push rods 103 drive the two side dies 104 to move relative to each other, and their strokes are on the same axis, enabling them to move closer or further apart with high consistency and accuracy. When a forging placed in the forming cavity 101a of the bottom die 101 needs to be forged a second time, the two electric push rods 103 are started synchronously, pushing the side dies 104 to move relative to each other along the predetermined same axis, and precisely inserting them into the forming cavity 101b between the bottom die 101 and the upper die 102 to perform secondary forging of the forging.

[0045] like Figures 1 to 4As shown, an electric push rod 105 is fixedly connected to the top of the machine body 1, and a support plate 106 is fixedly connected to the output end of the electric push rod 105. The upper mold 102 is fixedly installed at the bottom of the support plate 106.

[0046] It should be noted that when the upper die 102 moves downward, it cooperates with the lower die 101 to apply pressure to the forging located between the two, thereby completing the forging of the forging. The support plate 106 is suitable for providing a carrier for mounting and fixing the upper die 102.

[0047] like Figure 5 As shown, a molding cavity 101a is provided between the bottom mold 101 and the upper mold 102. Molding cavities 101b are provided on the left and right sides of the bottom mold 101 and the upper mold 102. The two side molds 104 are respectively adapted to the inner diameter of the molding cavity 101b.

[0048] It should be noted that the side mold 104 forms a closed and stable space with the bottom mold 101 and the upper mold 102, which ensures that the forging is subjected to uniform and all-round pressure during the forging process, thus guaranteeing the forming accuracy and quality of the forging. On the other hand, the tightly fitted structure can also effectively prevent metal material from overflowing during the forging process, improving material utilization and reducing waste generation.

[0049] like Figures 2 to 4 As shown, an electric push rod 107 is fixedly connected to the bottom of the body 1. The output end of the electric push rod 107 is fixedly connected to a top tube 107a. A slot is opened on the top tube 107a, and the top end of the top tube 107a contacts the bottom of the washer 217.

[0050] It should be noted that during the upward movement of the jacking pipe 107a, the groove can provide guidance and limit for the bend pipe 2191, ensuring that the bend pipe 2191 is always in the appropriate position when the jacking pipe 107a moves, avoiding the bend pipe 2191 from obstructing the vertical movement of the jacking pipe 107a, and ensuring the smooth progress of the entire lubricating release agent spraying process.

[0051] like Figure 5 As shown, the recycling component 22 includes two guide channels 221 formed on the bottom mold 101. The two guide channels 221 are symmetrically arranged on the left and right sides of the bottom mold 101, and the two guide channels 221 are respectively located below the forming cavity 101b.

[0052] It should be noted that excess lubricating release agent will flow out from the two molding cavities 101b. The guide groove 221 located below the molding cavity 101b can accurately guide the flow of this excess lubricating release agent, causing it to converge along the direction of the guide groove 221. This symmetrical arrangement ensures that the lubricating release agent flowing out from either the left or right side of the molding cavity 101b can be effectively collected.

[0053] like Figure 5 As shown, a collection groove 222 is provided on the bottom mold 101. The collection groove 222 is connected to two guide grooves 221 respectively. A flexible hose 223 is fixedly connected to the inner wall of the collection groove 222. The collection groove 222 is connected to the flexible hose 223.

[0054] It should be noted that the connection between the collection tank 222 and the hose 223, and the design of the hose 223 being fixed to the inner wall of the collection tank 222, allow the lubricating release agent collected in the tank to be conveniently discharged and collected through the hose 223. This complete recycling path design not only efficiently collects excess lubricating release agent, avoiding its waste and pollution to the working environment, but also provides convenient conditions for the secondary use of lubricating release agent.

[0055] In this embodiment, the specific implementation scenario is as follows: After spraying the inner wall of the forming cavity 101a, two electric push rods 103 can be driven to move the two side molds 104 away from each other. At this time, excess lubricating release agent will flow out through the two forming cavities 101b and be guided into the collection tank 222 through the two guide channels 221. The excess lubricating release agent can then be discharged and collected through the hose 223 for subsequent secondary use. This not only improves the utilization rate of the lubricating release agent and reduces waste, but also conforms to the concepts of environmental protection and economy, further optimizing the entire mold protection process before die forging. The preheated forging is then placed in the bottom mold. After the forging is placed in the forming cavity 101a of mold 101, the electric push rod 105 can be driven to move the support plate 106 and the upper mold 102 downward, so that the upper mold 102 and the bottom mold 101 cooperate to perform the first forging of the forging. Then, the two electric push rods 103 are driven to move the two side molds 104 closer to each other and insert them into the forming cavity 101b to perform the second forging of the forging. After the forging is completed, the two electric push rods 103 are driven to move away from each other, while the electric push rod 105 is driven to move the upper mold 102 upward. At this time, the electric push rod 212 is driven to move upward to push the forging out of the mold, so as to achieve the effect of rapid demolding.

[0056] Working principle:

[0057] 1. Due to the high temperature and high pressure environment generated during the die forging of preheated forgings, the mold is easily damaged. Therefore, it is necessary to spray a lubricating release agent on the inner wall of the mold before die forging to protect it. Before placing the preheated forging in the forming cavity 101a of the bottom mold 101 for forging, the hose 2193 is connected to an external pump. The lubricating release agent is pumped into the nozzle 219 through the hose 2193. After the lubricating release agent fills the cavity of the slide bar 212, the drive motor... The second push rod 105 drives the support plate 106 to move downward, so that the upper mold 102 and the bottom mold 101 are joined together. The electric push rods 103 on the left and right sides drive the side molds 104 to move closer to each other, so that the two side molds 104 slide into the forming cavity 101b between the bottom mold 101 and the upper mold 102 respectively. At this time, the forming cavity 101a is isolated from the outside. Then, the electric push rod 107 can be driven to move the top tube 107a upward. The top tube 107a has a groove. The bend 2191 is located inside the slot of the top tube 107a. After the top tube 107a contacts the bottom of the washer 217, it drives the slide rod 212 to move upward as a whole, so that multiple grooves 216 are located in the forming cavity 101a. At this time, under the action of the external pump, the lubricating release agent injected into the slide rod 212 will squeeze the valve block 215 inside the multiple grooves 213 to move upward, and spray out through the multiple grooves 216 to spray the inner wall of the forming cavity 101a, thereby providing the expected protection for the inner walls of the bottom mold 101 and the upper mold 102. This spraying method can not only isolate the air inside the forming cavity 101a before spraying to prevent the lubricating release agent from leaking out, but also ensure that the lubricating release agent can be injected into the forming cavity 101a in all directions without dead angles, ensuring uniform spraying of every part of the mold inner wall, maximizing the protection effect, providing a solid guarantee for subsequent die forging operations, effectively extending the service life of the mold, and reducing production costs.

[0058] Second, multiple springs 214 and valve block 215 cooperate with each other so that when spring 214 is in normal condition, valve block 215 is located at the connection between groove 216 and groove 213, isolating the internal cavity of slide rod 212 from the external environment, and forming a one-way valve so that the lubricating release agent can only be sprayed out, avoiding the backflow of the lubricating release agent, ensuring the smooth progress of the spraying process and the rational use of the lubricating release agent, and further improving the reliability and stability of the entire mold protection process.

[0059] Third, the nozzle 219 and the inner wall of the slide bar 212 are connected by threads, which makes the nozzle 219 easy to disassemble, thereby enabling the internal cleaning and maintenance of the slide bar 212. At the same time, the bent tube 2191 and the connecting ring 2192 cooperate with each other to ensure that the bent tube 2191 can rotate on the inner wall of the nozzle 219. This ensures that when the top tube 107a moves upward, the bent tube 2191 is inside the groove of the top tube 107a, avoiding the bending tube 2191 from affecting the up and down movement of the top tube 107a and ensuring the stable operation of the entire spraying system.

[0060] Fourth, after spraying the inner wall of the forming cavity 101a, the two electric push rods 103 can be driven to move the two side molds 104 away from each other. At this time, the excess lubricating release agent will flow out through the two forming cavities 101b and be guided into the collection tank 222 through the two guide channels 221. The excess lubricating release agent can then be discharged and collected through the hose 223 for subsequent secondary use. This not only improves the utilization rate of the lubricating release agent and reduces waste, but also conforms to the concept of environmental protection and economy, further optimizing the entire process of mold protection before die forging.

[0061] Fifth, after the preheated forging is placed in the forming cavity 101a of the bottom mold 101, the electric push rod 105 can be driven to move the bearing plate 106 and the upper mold 102 downwards, so that the upper mold 102 and the bottom mold 101 cooperate to perform the first forging of the forging. Then, the two electric push rods 103 are driven to move the two side molds 104 closer to each other and insert them into the forming cavity 101b to perform the second forging of the forging. After the forging is completed, the two electric push rods 103 are driven to move away from each other, while the electric push rod 105 is driven to move the upper mold 102 upwards. At this time, the electric push rod 212 is driven to move upwards to push the forging out of the mold, achieving the effect of rapid demolding, improving production efficiency and reducing the production cycle of a single forging.

[0062] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
