Description

Technical Field

[0001] This invention relates to the technical field of automotive swing arm processing, and particularly to an equipment and process for producing automotive swing arms based on liquid forging. Background Technology

[0002] The production of automotive control arms using liquid forging is an advanced manufacturing process with significant technological advantages and application potential. Liquid forging technology combines the advantages of casting and forging, enabling the production of parts with complex shapes, excellent mechanical properties, and high dimensional accuracy. It is widely used in the automotive industry, including the manufacturing of key components such as steering knuckles and control arms.

[0003] For example, Chinese patent CN117548654B discloses an integrated casting equipment for automotive lower control arms, relating to the field of automotive parts manufacturing technology. The equipment includes a base steel plate with a forming module mounted on it. The forming module comprises an upper mold and a lower mold. By cooperating with a pusher assembly and the forming module, the already formed lower control arm can be automatically pushed out when the upper and lower molds separate, thus eliminating the need for manual operation.

[0004] However, the above-mentioned device still has some shortcomings in actual use:

[0005] 1. In the existing technology, liquid raw materials are stored in a tank. When product forging is required, they are transported to the mold through a pipeline for preparation. However, it should be noted that after the pipeline transports the liquid raw materials, a certain amount of liquid raw materials will remain inside. During the transportation process, the pipeline located between the tank and the mold will be affected by the external environment, causing its temperature to be inconsistent with the temperature inside the tank. Because the temperature inside the pipeline is lower, the liquid raw materials remaining in the pipeline may solidify.

[0006] 2. Secondly, in the existing technology, the mold of the existing device is only set with a single shape and inner cavity. Therefore, when it is working, it can only process products of a single size and cannot process products of multiple different sizes. Therefore, the entire device has a certain degree of limitation.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing devices. Summary of the Invention

[0016] One side of the clamping rod is provided with a serrated structure, and the active fixing frame is provided with a serrated structure that meshes with the serrated structure on the clamping rod.

[0017] Preferably, the support platform is also symmetrically provided with a number of guide pillars along the width direction, and the side walls of the fixed mold and the moving mold are also provided with receiving blocks for the guide pillars to abut against, and the receiving blocks are provided with arc grooves for the guide pillars to fit.

[0018] Two sets of symmetrically distributed guide plates are provided between the guide columns on the support platform.

[0047] The following combination Figures 1-11 This application will be described in further detail.

[0048] This application discloses an equipment and process for producing automotive swing arms based on liquid forging; this equipment is mainly used in the processing and preparation of automotive swing arms.

[0049] In the existing technology, liquid raw materials are stored in a tank. When product forging is required, they are transported to the mold through a pipeline for preparation. However, it should be noted that after the liquid raw materials are transported, a certain amount of liquid raw materials will remain inside the pipeline. During the transportation process, the pipeline located between the tank and the mold will be affected by the external environment, causing its temperature to be inconsistent with the temperature inside the tank. Because the temperature inside the pipeline is lower, the liquid raw materials remaining in the pipeline may solidify.

[0050] Secondly, in the existing technology, the mold of the existing device is only set with a single shape and inner cavity. Therefore, when it is working, it can only process products of a single size and cannot process products of multiple different sizes. Thus, the entire device has a certain degree of limitation.

[0051] Therefore, in order to solve the above problems, this application proposes a device for producing automotive swing arms based on liquid forging.

[0052] See Figure 1 As shown, this application discloses a device for producing automotive swing arms based on liquid forging, which includes a stationary support platform 1.

[0053] The forging component 2 is used to forge liquid ceramic aluminum raw materials. The forging component 2 includes a fixed die 20 and a moving die 21. The fixed die 20 and the moving die 21 are vertically distributed, so that the moving die 21 moves along the length direction of the support platform 1.

[0054] It should be noted that in the initial state, the fixed mold 20 and the moving mold 21 are in a state of separation.

[0055] In practice, the raw materials for preparing the car swing arm are first melted to make them molten. It should be noted that the raw materials in this application are mainly ceramic aluminum.

[0056] Aluminum-ceramic composite material is a novel type of aluminum-based composite material that possesses superior properties such as high stiffness, high strength, fatigue resistance, low expansion, high damping, and high temperature resistance, while retaining the easy-to-form and easy-to-process characteristics of aluminum alloys. This material significantly enhances its overall performance by adding relevant elements to the molten aluminum alloy and utilizing melt control technology to generate nano-ceramic particles.

[0057] After the product is melted, it undergoes refining and degassing to remove impurities from the molten aluminum-ceramic mixture. It is then conveyed between the fixed die 20 and the moving die 21 of the forging component 2. After cooling, a preliminary product, namely the automotive swing arm, is formed. However, it should be noted that the shape and size of the cavity between the fixed die 20 and the moving die 21 are fixed. When adjustments to these dimensions are needed, existing technology typically requires disassembling the fixed die 20 and the moving die 21, and then installing fixed dies 20 and the moving die 21 with different shapes and sizes of cavities.

[0058] To simplify the process of changing the fixed mold 20 and the moving mold 21, this application proposes a switching unit 3. This switching unit 3 allows for the rapid switching between different types of fixed molds 20 and moving molds 21, thereby ensuring that the device can process automotive swing arms of different sizes and shapes. Details are as follows:

[0059] See Figure 2 and Figure 3 As shown, the support platform 1 is also provided with two sets of symmetrically distributed switching parts 3; the switching part 3 includes two sets of switching rollers 30 that rotate on the support platform 1 and are arranged in a rectangular shape. The two sets of rectangularly distributed switching rollers 30 are respectively fitted with switching chains 31, and the two sets of switching chains 31 are located on the same horizontal plane. Several sets of forging parts 2 are equally spaced on the two switching chains 31.

[0060] It should be noted that the switching chain 31 of this application is provided with four sets of fixed molds 20 and moving molds 21 with different inner cavities, and they are named in sequence as the first fixed mold, the first moving mold; the second fixed mold, the second moving mold; the third fixed mold, the third moving mold; and the fourth fixed mold, the fourth moving mold.

[0061] On the support platform 1, two sets of rectangularly distributed switching rollers 30 are equipped with control gears 10 on one side. One of the control gears 10 is meshed with a reversing gear 11. A control chain 12 is sleeved between the reversing gear 11 and the control gear 10 that is away from the reversing gear 11.

[0062] In practice, rotating one side of the switching roller 30 causes the reversing gear 11 at its bottom to rotate. When the reversing gear 11 rotates, it drives the other side of the switching roller 30 to rotate through the control chain 12. At this time, the two sets of switching rollers 30 rotate in opposite directions, and the control chains 12 on the two switching rollers 30 also rotate synchronously relative to each other.

[0063] When the two control chains 12 rotate synchronously relative to each other, the corresponding first fixed mold and first moving mold on the side wall of the two control chains 12 move synchronously until the first fixed mold and the first moving mold move synchronously to the designated processing area on the support platform 1.

[0064] When the corresponding second fixed mold and second moving mold are required to process the product, the switching roller 30 on one side is rotated and the above operation is repeated to drive the corresponding second fixed mold and second moving mold on the control chain 12 to move to the designated processing area on the support platform 1. This process is repeated sequentially to achieve position adjustment of the third fixed mold, the third moving mold, and the fourth fixed mold and the fourth moving mold.

[0065] However, it should be noted that the fixed mold 20 and the moving mold 21 are connected to the switching chain 31 by quick disassembly and quick installation. This makes it easy to replace the second fixed mold, the second moving mold, or the third fixed mold, the third moving mold, or the fourth fixed mold and the fourth moving mold when the first fixed mold and the first moving mold are working.

[0066] See Figure 4 and Figure 5As shown, a quick-release assembly 4 is also provided between the forging component 2 and the switching chain 31. The quick-release assembly 4 includes passive fixing frames 40 installed at equal intervals on the side wall of the switching chain 31. The back side of the passive fixing frame 40 is provided with a fixing groove 41. An active fixing frame 42 is installed in the fixing groove 41. The active fixing frame 42 is connected to the fixed mold 20 and the moving mold 21 of the forging component 2, respectively.

[0067] The fixed mold 20 and the moving mold 21 are also provided with quick-locking posts 43 arranged in a rectangular shape on the side near the active fixing frame 42. The quick-locking posts 43 slide through the passive fixing frame 40, and the passive fixing frame 40 has mounting holes for the quick-locking posts 43.

[0068] The quick-locking post 43 has a T-shaped structure.

[0069] First, it should be noted that the passive fixing frame 40 is installed on the control chain 12 with bolts and nuts to ensure the stability of the passive fixing frame 40. After the passive fixing frame 40 and the control chain 12 are stably connected, the quick-lock pin 43 on the active fixing frame 42 is inserted into the mounting hole on the passive fixing frame 40, so that the active fixing frame 42 abuts against the fixing groove 41 of the passive fixing frame 40 and they fit together.

[0070] Once the two are in place, the quick-locking post 43 and the passive fixing frame 40 quickly align.

[0071] The switching unit 3 in this application can switch the positions of the fixed mold 20 and the moving mold 21 used for manufacturing automotive swing arms, ensuring that the device can manufacture automotive swing arms of different shapes and sizes, reducing the cumbersome steps of changing the fixed mold 20 and the moving mold 21, improving the efficiency of switching between the two, and thus indirectly improving the efficiency of automotive swing arm manufacturing.

[0072] Let's look again. Figure 4 and Figure 5 The diagram shows the structure of the passive fixing frame 40 and the active fixing frame 42 interlocking in this application. The passive fixing frame 40 is provided with a clamping screw 401, and a clamping block 400 is screwed onto the clamping screw 401. Inclined rods 402 are installed on both sides of the clamping block 400 along its length. A clamping rod 403 is provided at the end of the inclined rod 402 away from the clamping block 400. One side of the clamping rod 403 faces the fixing groove 41 of the passive fixing frame 40. A clamping spring 404 is provided between the clamping rod 403 and the passive fixing frame 40.

[0073] The clamping rod 403 has a serrated structure on one side, and the active fixing frame 42 has a serrated structure that meshes with the serrated structure on the clamping rod 403.

[0074] In practice, after the active fixing frame 42 is inserted into the fixing groove 41 of the passive fixing frame 40, the quick-lock pin 43 is also inserted into the passive fixing frame 40. At this time, the clamping screw 401 is rotated, and the clamping screw 401 drives the clamping block 400 to move upward. When the clamping block 400 moves upward, the clamping rods 403 on both sides are controlled by the inclined rod 402 to move synchronously into the fixing groove 41 on their inner side until the serrated structure on the clamping rod 403 meshes with the serrated structure on the active fixing frame 42. At this time, the engagement of the passive fixing frame 40 and the active fixing frame 42 is completed.

[0075] After the fixed mold 20 and the moving mold 21 have switched, liquid raw materials can be injected into them to prepare the automobile swing arm, as shown below:

[0076] See Figure 6 As shown, the support platform 1 is also equipped with an installation box 5 for carrying the ceramic aluminum solution. The bottom of the installation box 5 is provided with a discharge port 50, and a syringe 51 is slidably installed at the discharge port 50. An injection electric rod 52 is installed on one side of the installation box 5. The injection electric rod 52 is mounted on the support platform 1 through a bracket. A cover plate 53 is installed on the output end of the injection electric rod 52, and the cover plate 53 abuts against the bottom of the discharge port 50.

[0077] In the initial state, the cover plate 53 abuts against the discharge port 50 of the mounting box 5 to block it and separate the syringe 51 from the mounting box 5.

[0078] When it is necessary to prepare the car swing arm, the injection electric rod 52 is activated. The injection electric rod 52 opens the discharge port 50 at the bottom of the mounting box 5 through the cover plate 53. At this time, the liquid raw material in the mounting box 5 enters the syringe 51 and fills the syringe 51.

[0079] It should be noted that the syringe 51 has a known door at its storage port 512, and the syringe 51's storage port 512 opens simultaneously when the cover plate 53 is opened.

[0080] Let's look again. Figure 6 , Figure 7 and Figure 8 As shown, hydraulic cylinders 60 are installed on both sets of guide plates 47. Casting rods 66 are installed on the output ends of both sides of the hydraulic cylinders 60. The casting rods 66 extend towards the fixed mold 20 and the moving mold 21. Casting plates 65 with a U-shaped structure are installed on both sides of the fixed mold 20 and the moving mold 21. The casting rods 66 abut against the casting plates 65.

[0081] A right-angle toothed plate 61 is also installed on the output end of the hydraulic cylinder 60. A linkage gear 62 rotates on the right-angle toothed plate 61. A linkage rack 63 meshes on the linkage gear 62. A loop frame 67 is provided on the linkage rack 63. An active block 69 is slidably mounted on the guide frame 54 at the bottom of the loop frame 67. A passive block 68 is installed on the injection body 510.

[0082] In practice, the hydraulic cylinder 60 is activated. The output end of the hydraulic cylinder 60 drives the moving mold 21 and the fixed mold 20 to move closer to each other. During this process, the hydraulic cylinder 60 drives the right-angle gear plate 61 to move synchronously. At the same time, the right-angle gear plate 61 drives the linkage gear 62 to rotate. The linkage gear 62 drives the linkage rack 63 to move. The linkage rack 63 controls the injection body 510 to move towards the fixed mold 20 and the moving mold 21 through the loop frame 67, until the injection needle 511 on the injection body 510 is inserted into the fixed mold 20 and the moving mold 21. In the injection guide groove between 1, the fixed mold 20 and the moving mold 21 are then attached together. At this time, the pump in the injection body 510 is activated, and the quantitative liquid raw material stored inside is injected into the cavity between the fixed mold 20 and the moving mold 21 through the injection needle 511. After the existing known cooling devices on the fixed mold 20 and the moving mold 21 cool and shape them, the fixed mold 20 and the moving mold 21 are separated. At this time, the initial preparation of the car swing arm is completed. Then, the required car swing arm is finally made through subsequent grinding and other processes.

[0083] It should be noted that the injection body 510 is provided with a passive block 68. When the injection body 510 is switched, each injection body 510 is provided with a passive block 68. The active block 69 can abut against the passive block 68 and pull the passive block 68 and the injection body 510 to move in the direction of the fixed mold 20 and the moving mold 21.

[0084] See Figure 9 and Figure 10 As shown, the support platform 1 is also symmetrically provided with a number of guide columns 44 along the width direction. The side walls of the fixed mold 20 and the moving mold 21 are also provided with receiving blocks 45 for the guide columns 44 to abut against. The receiving blocks 45 have arc grooves for the guide columns 44 to fit together.

[0085] Two sets of symmetrically distributed guide plates 47 are provided between the guide columns 44 on the support platform 1. The two sets of guide plates 47 slide relative to each other along the width direction of the support platform 1, and an electric push rod 46 is provided between the two sets of guide plates 47. The electric push rod 46 is located on the support platform 1.

[0086] In the initial state, the guide post 44 and the guide clamp 47 are far away from the fixed mold 20 and the moving mold 21 to avoid interference between the fixed mold 20 and the moving mold 21 and the guide clamp 47 during the switching process.

[0087] To ensure stability when the fixed mold 20 and the moving mold 21 are close to each other, this application also proposes a guide post 44 and a receiving block 45, which are installed on the fixed mold 20 and the moving mold 21.

[0088] The electric push rod 46 has a bidirectional telescopic structure, which can control the synchronous relative movement of the two sets of guide plates 47.

[0089] In practice, the electric push rod 46 is activated, and the movable end of the electric push rod 46 retracts inward. At this time, the electric push rod 46 controls the guide column 44 to move towards the receiving block 45 of the fixed mold 20 and the moving mold 21 through the guide clamp 47, until the guide column 44 abuts against the arc groove of the receiving block 45. At this time, the fixed mold 20 and the moving mold 21 can only move along the guide column 44.

[0090] When the guide post 44 abuts against the receiving block 45, the casting rods 66 on both sides of the hydraulic cylinder 60 on the guide clamp 47 also abut against the casting plate 65 on the side wall of the fixed mold 20 and the moving mold 21. The casting plate 65 has a U-shaped structure.

[0091] Looking back Figure 7 and Figure 8 As shown, the bottom of the mounting box 5 is provided with a guide frame 54, and a rotating disk 55 is installed inside the guide frame 54. Guide rods 56 are installed at equal intervals along the circumferential direction on the rotating disk 55.

[0092] A circular groove is provided on one side of the guide frame 54 for the injection body 510 to extend and retract.

[0093] The syringe 51 includes an injection body 510 and an injection needle 511 connected to one side of the injection body 510. The injection body 510 has a receiving port 512 corresponding to the discharge port 50 at the bottom of the mounting box 5. The tail of the injection body 510 is connected to the top of the guide rod 56.

[0094] It should be noted that the guide frame 54 is made of thermal insulation material, which can ensure that the temperature of the injection body 510 is maintained within a stable range, thereby reducing the temperature difference between it and the inside of the mounting box 5.

[0095] It should be noted that a guide spring is provided on the guide rod 56. When the injection body 510 is moved, the guide spring is stretched and has a certain elasticity. After the injection body 510 loses external force, the guide spring can control the injection body 510 to return to the guide frame 54.

[0096] When adjusting different types of fixed molds 20 and moving molds 21, the internal cavity sizes between the fixed molds 20 and moving molds 21 are also different. Therefore, it is also necessary to adjust the injection body 510 used to store liquid raw materials. At this time, rotate the rotating disk 55 on the guide frame 54 so that the corresponding injection body 510 abuts against the discharge port 50 at the bottom of the mounting box 5.

[0097] Furthermore, the guide frame 54, like the mounting box 5, has a heat preservation function to ensure that the liquid raw material remains constant within a certain range.

[0098] After the injection body 510 extends rapidly, it injects the liquid material it carries into the cavity between the fixed mold 20 and the moving mold 21. This avoids the liquid material from staying in the injection body 510 for a long time, thus effectively preventing the liquid material from solidifying inside the injection body 510. Compared with the traditional pipeline transportation method, this not only avoids the liquid material from solidifying and causing pipeline blockage, but also reduces the loss of liquid material.

[0099] See Figure 11 The following diagram illustrates the process for producing automotive control arms using liquid forging in this application:

[0100] S1. Raw material preparation: First, select a suitable aluminum alloy material - ceramic aluminum, and melt it in an electric furnace until it is in a molten state.

[0101] S2. Refining and Degassing: The molten ceramic-aluminum material is poured into the installation box 5, and then degassed and slag removed to improve its purity.

[0102] S3, Liquid forging: Rotate the switching roller 30 on one side to control the two sets of control chains 12 to rotate relative to each other, so that the required fixed mold 20 and moving mold 21 rotate to the specified position, and the inner cavities of the fixed mold 20 and moving mold 21 are relatively distributed. Then rotate the rotary disk 55 to control the corresponding injection body 510 to move to the specified position.

[0103] Subsequently, the hydraulic cylinder 60 is activated, causing the moving mold 21 and the fixed mold 20 to move closer to each other. During this process, the injection body 510 moves toward the moving mold 21 and the fixed mold 20. When the two come into contact, the injection needle 511 of the injection body 510 is already positioned between them. Then, the injection body 510 injects liquid raw materials into its interior for pouring. After pouring is completed, pressure is applied to ensure that the metal fully fills the mold cavity and is maintained for a certain period of time to complete the pressurization.

[0104] S4. Cooling and Demolding: The metal is cooled in the mold. During the cooling process, the metal will solidify and undergo plastic deformation to form the required shape. After cooling is completed, the finished swing arm is removed from the mold by the demolding mechanism.

[0105] S5. Product finishing: After it is taken out, it is subjected to X-ray flaw detection, burr grinding, fine heat treatment, shot blasting, machining (turning and milling), surface passivation treatment, hot drying, inspection and testing (mechanical properties), and fine assembly.

[0106] S6. Product Packaging: The product is then laser-marked and packaged, and then collected in a unified manner.

[0107] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
