Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically to a fully automated die forging production line for automotive parts. Background Technology

[0002] Automated die forging technology for automotive parts is a core direction for the automation transformation of the equipment manufacturing industry. It is mainly applied to the mass production of key components such as engine connecting rods, crankshafts, and steering knuckles. Its core objective is to solve the pain points of traditional die forging processes, such as low efficiency, large quality fluctuations, and reliance on manual labor. Simultaneously, it aims to overcome the limitations of existing demolding technologies. With the automotive industry's increasing demands for precision and strength in parts, coupled with rising labor costs and production pressures from an aging population, traditional die forging methods are no longer sufficient to meet the demands of large-scale, high-precision production. As core basic components of automobiles, die forgings require multiple processes including billet preparation, pre-forging, final forging, and trimming. The deep penetration of automation technology has become an inevitable trend for industry upgrading, driving the transformation of die forging production towards integration, digitalization, and green manufacturing.

[0003] Chinese patent CN202510307311.0 discloses an automatic processing equipment for gear disc forgings, including a hot forging press. The equipment is characterized by: a roughing station, a pre-forging station, a final forging station, and a punching station arranged sequentially from left to right on the worktable of the hot forging press; a transfer robot arm capable of lifting, moving forward and backward, and moving left and right is located behind the worktable; a blank loading device is located on the left side of the worktable, and a forging unloading device is located on the right side. This automatic processing equipment for gear disc forgings is rationally designed, convenient, and practical. It enables the completion of multiple processes—roughing, pre-forging, final forging, and punching—of gear disc forgings on a single hot forging press, reducing the transfer distance of the forgings. Furthermore, the use of a robot arm achieves fully mechanized operation for loading, transferring, and unloading, resulting in high processing efficiency, reduced manual intervention, and improved production safety.

[0004] In the forging process of automotive parts, to ensure the forgings smoothly detach from the mold cavity and avoid problems such as forging damage and mold wear caused by the forgings sticking to the mold, a release agent needs to be evenly sprayed onto the surface of the mold cavity before mold closing at the end of each forging cycle. However, in actual production, traditional release agent spraying operations generally have the following technical problems: Release agents are mostly liquid or mist media. When sprayed into the mold cavity, the release agent droplets are easily splashed and spread under the action of high-pressure airflow. These diffused release agents not only adhere to the surface of the mold cavity, but also inevitably drift onto the surface of the die-cast parts that have been die-cast but have not yet fully cooled or are in the process of being removed.

[0005] If mold release agent adheres to the surface of die castings, it will directly affect their subsequent processing and performance. On the one hand, mold release agent residue can cause appearance defects such as oil spots, flow marks, and color differences on the surface of die castings, reducing the surface quality of the product. Especially for die castings with high surface finish requirements, such defects often require additional grinding and cleaning processes to eliminate, which significantly increases production costs and production cycle. On the other hand, mold release agent residue can affect the adhesion of subsequent processing processes such as coating and electroplating on the surface of die castings, leading to quality problems such as coating peeling and uneven plating, which seriously affects the assembly accuracy and reliability of die castings. In addition, if the mold release agent contains harmful components such as sulfur and phosphorus, it may react with the metal at high temperatures or remain inside the forging, affecting the mechanical properties of the metal material (such as strength and toughness).

[0006] In view of the shortcomings of the existing technology, there is an urgent need for a fully automated die forging production line for automotive parts to solve the problem of surface contamination of die castings caused by droplet splashing and diffusion during the release agent spraying process, and to improve the automation level and product quality stability of automotive parts die forging production. Summary of the Invention

[0007] To address existing technical problems, this invention provides a fully automated die forging production line for automotive parts. This line achieves fully automated die forging operations through integrated design. Its core innovation lies in the collaborative working mechanism of a semi-enclosed protective component and an intelligent material transfer device. Specifically, by setting up a flip-up protective cover with an L-shaped structure and equipped with a double-baffle mechanism, in conjunction with a linkage mechanism with the grippers, when the release agent is sprayed, the grippers on both sides move the die-cast part between the die-casting processing stations. The protective cover flips to a preset position to form a semi-enclosed space. A magnetic suction component on the inner side drives the two side baffles to converge towards the center, forming a bucket-shaped structure, effectively intercepting the release agent droplets splashing from both sides of the die-cast part. This invention can improve die forging production efficiency and, compared to traditional processes, better meets the development needs of lightweight and high-strength automotive parts, effectively solving the shortcomings of existing technologies.

[0014] As an improvement, magnets are provided on the outer side of the gripping part of the claw and the bottom of the baffle. The magnets at the bottom of the baffles on both sides are influenced by the magnets on the outer side of the claw and move towards the middle. Finally, the bottoms of the baffles on both sides attract each other to form a bucket shape.

[0015] As an improvement, the adjustment mechanism includes a mounting base, a lateral control assembly, and a lifting assembly; The lateral control component includes a lateral drive motor, a lead screw, and a lead screw nut. The lateral drive motor is fixedly mounted on the mounting base. The lead screw is connected to the output end of the lateral drive motor via a coupling.

(4) The material transfer device of the present invention, through the cooperation of the crossbeam, the gripper and the adjustment mechanism, realizes the precise and efficient movement of the die casting between the die casting processing station and the trimming station. In particular, the telescopic setting of the gripper and the contour clamping part can adapt to die castings of different shapes and sizes, and improve the versatility and flexibility of the production line.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Example 1: like Figures 1-18 As shown, a fully automated die forging production line for automotive parts includes: The medium-frequency furnace 1, the transfer device 2, the forging device 3, and the spraying assembly 4 are arranged sequentially along the processing direction; The transfer device 2 is located between the intermediate frequency furnace 1 and the forging device 3. The transfer device 2 connects the output end of the intermediate frequency furnace 1 and the input end of the forging device 3. The transfer device 2 transports the die-cast parts heated by the intermediate frequency furnace 1 to the forging device 3. This design eliminates the need for manual intervention in the transfer of die-cast parts. On the one hand, it completely avoids the safety accidents that may be caused by manual contact with high-temperature die-cast parts, improving the operational safety of the production line. On the other hand, it avoids problems such as bumps and drops of die-cast parts during manual transfer, ensuring the integrity of the die-cast parts. At the same time, the automated conveying rhythm of the transfer device can be precisely matched with the heating rhythm of the intermediate frequency furnace and the processing rhythm of the forging device, avoiding the situation of "waiting for materials and stopping work" or "accumulation of die-cast parts", ensuring the continuous and stable operation of the production line, and further improving the processing output per unit time. The forging device 3 includes several sets of die-casting processing stations 31 and trimming stations 32 arranged sequentially along the horizontal direction. The die-casting processing stations 31 are responsible for the gradual die-casting and shaping of the die-cast parts. Multiple stations are designed according to the complex structure of automotive parts, which can realize "progressive forming" and avoid problems such as cracking of die-cast parts and uneven internal structure caused by excessive pressure in a single die-casting, thus ensuring the structural strength and dimensional accuracy of the forgings. The trimming station 32 is responsible for removing excess material edges of the die-cast parts after die-casting, ensuring that the shape of the forgings meets the assembly requirements of automotive parts. Material transfer devices 5 are provided on both sides of the die-casting processing stations 31 and the trimming station 32. The material transfer devices 5 drive the die-cast parts to move between the die-casting processing stations 31 and the trimming station 32, realizing the automated transfer of the die-cast parts. A spraying station 33 is provided between the die casting processing stations 31. The spraying station 33 is located between the upper and lower molds of the die casting mold. The gap is used to accommodate the spraying component 4, so that the spraying component 4 can extend into the space between the upper and lower molds to spray the release agent. The spraying component 4 is disposed on one side of the forging device 3. The spraying component 4 sprays a release agent onto the mold at the die casting processing station 31. When the die casting is moved to the designated position, the spraying component 4 sprays a release agent onto the mold to ensure that the die casting can be successfully demolded in the subsequent die casting process, and to avoid damage to the die casting or production interruption caused by mold adhesion. The material transfer device 5 is provided with protective components 51 and grippers 54 on both sides. The protective components 51 include a protective cover 511 and a baffle 512. The protective cover 511 is installed on the material transfer device 5. The baffle 512 is slidably installed on the inner walls of both sides of the protective cover 511. The grippers 54 on both sides are arranged opposite to each other. The grippers 54 are hinged to the protective cover 511. When the grippers 54 on both sides move towards the middle to clamp the die casting, the protective cover 511 flips with the extension and retraction of the grippers 54, forming a semi-enclosed space together with the baffles 512 on both sides, to prevent the release agent from splashing to both sides during the spraying process and affecting the die casting.

[0026] It should be noted that in traditional material transfer devices, due to the lack of effective protective structures during part picking and mold release agent spraying, the high-pressure atomized mold release agent tends to splash randomly in all directions, with a splash range of 300-500mm and an effective utilization rate of only 40%-60%. When the mold release agent droplets come into contact with the surface of the die casting, which is still at a high temperature, they will undergo a violent phase change due to instantaneous vaporization at high temperature, forming a local vapor film and turbulence. This not only causes uneven distribution of the mold release agent and affects the subsequent demolding effect, but also forms defects such as cold spots, water stains, and oxide inclusions on the surface of the die casting, resulting in excessive surface roughness, reduced dimensional accuracy, and even local structural abnormalities, reducing the mechanical properties and yield of the product. To address this, the present invention sets up protective covers and sliding baffles on both sides of the material transfer device that can rotate in conjunction with the grippers. When the grippers hold the die casting, a semi-enclosed protective space is formed, effectively constraining the spraying range of the mold release agent, preventing the mold release agent from splashing laterally and contacting the high-temperature surface of the die casting, thereby stabilizing the molding quality, improving the product yield, and improving the working environment.

[0027] The transfer device 2 includes a conveyor line 21 and a slide 22. The conveyor line 21 is located on one side of the output end of the intermediate frequency furnace 1. The slide 22 connects the conveyor line 21 and the forging device 3. The conveyor line 21 is equipped with a detection station 23, which performs temperature detection on the heated die casting. The detection station 23 includes a pusher cylinder 231 and a detection component 232. The pusher cylinder 231 is disposed on one side of the conveyor line 21 and is extended and retracted along the conveying direction perpendicular to the conveyor line 21. The detection component 232 is disposed above the conveyor line 21. A discharge channel 233 is disposed on the other side of the conveyor line 21 corresponding to the pusher cylinder 231. When the die casting is conveyed to the inspection station 23, the inspection component 232 uses a temperature sensor to quickly and accurately measure the temperature of the die casting and transmit the data to the control system. If the temperature of the die casting meets the preset requirements, it continues to be conveyed to the forging device 3 through the slide 22 for forging. If the temperature of the die casting does not meet the requirements, the pusher cylinder 231 pushes the die casting to the discharge channel 233 and discharges it from the production line to ensure that only die castings with qualified temperatures enter the subsequent processing stage, thereby ensuring the quality and performance of the forgings.

[0028] It should be noted that the transfer device 2 also includes a top-loading assembly 24, which is installed at the output end of the slide 22. The top-loading assembly 24 includes a receiving seat 241 and a top-loading cylinder 242. The receiving seat 241 is located at the end of the slide 22 and is used to receive the die-casting parts sliding down the slide. The receiving seat 241 is oscillatingly mounted on the forging device 3 and is installed between the two crossbeams 52. The top-loading cylinder 242 is installed below the receiving seat 241, and its output end is connected to the receiving seat 241. When the die-casting parts slide down... When the die casting reaches the receiving seat 241, the top-loading cylinder 242 is activated, lifting the die casting to a designated angle so that the subsequent material transfer device 5 can accurately grasp the die casting and realize the automated transfer of the die casting. This design effectively avoids the die casting from being affected by accumulation or jamming at the end of the slide 22, thus improving the reliability and stability of the transfer device 2. At the same time, the setting of the top-loading component 24 also enables the die casting to maintain a stable posture during the feeding process, reducing the failure to grasp or the processing error caused by the tilting or shaking of the die casting, and further improving the processing accuracy and product quality of the production line.

[0029] It should be further explained that the initial state of the receiving seat 241 is consistent with the inclination angle of the slide 22 to ensure that the die-casting part can slide in smoothly. When the top material cylinder 242 drives the receiving seat 241 to flip from the inclined state to the vertical state, the distance between the die-casting part on the receiving seat 241 and the next processing station is equal to the distance between each processing station. This design effectively ensures that the material transfer device 5 can accurately and stably clamp the die-casting part, thereby improving the operating accuracy and reliability of the automated production line.

[0030] Furthermore, the material transfer device 5 includes a crossbeam 52 and an adjustment mechanism 55; The crossbeam 52 is symmetrically arranged on both sides of the die-casting processing station 31 and the trimming station 32, which can ensure structural stability while keeping the jaws 54 on both sides moving synchronously, thereby improving the positioning accuracy of the die-casting part when switching between stations. The grippers 54 are provided in several sets, and the grippers 54 are symmetrically installed on the crossbeams 52 on both sides. The grippers 54 are telescopic relative to the crossbeams 52, and can be adaptively adjusted according to the size, shape or processing requirements of the die-casting parts, thereby improving the compatibility of the material transfer device with products of different specifications. The grippers 54 are correspondingly set with the die-casting processing station 31 and the trimming station 32, so that the die-casting parts can be quickly and accurately transferred to the next station after die-casting, reducing intermediate transfer time and improving overall processing efficiency. When switching stations, the crossbeams 52 on both sides move closer to the middle, and the grippers 54 on both sides move closer to the middle accordingly. The grippers 54 on both sides can adaptively adjust after gripping the die-casting parts. This structure makes the clamping force more uniform and stable, avoiding the die-casting parts from shifting or falling due to uneven force on one side. At the same time, with the adaptive adjustment of the grippers, high-precision positioning of the die-casting parts is achieved, ensuring that the position remains consistent during the transfer process, and significantly improving the reliability and synchronization of the material transfer action. The adjustment mechanism 55 is disposed on both sides of the forging device 3. The adjustment mechanism 55 is connected to both ends of the crossbeam 52. The adjustment mechanism 55 controls the movement of the crossbeam 52 on both sides to drive the die casting to switch positions. By synchronously driving the crossbeam 52 on both sides, the adjustment mechanism 55 keeps the die casting stable when switching positions, avoiding position displacement or damage to the die casting caused by uneven force. In addition, the symmetrically arranged adjustment mechanism 55 can make the crossbeam more evenly stressed, improving the overall rigidity and service life of the equipment.

[0031] Furthermore, the gripper 54 includes a clamping part 540 and a connecting part 541. The clamping part 540 is configured to conform to the outer side wall of the die casting, which can fit closely to the surface of the die casting, improve clamping stability, and avoid damage to the surface of the die casting due to mismatch of the clamping surfaces. The clamping part 540 is fixedly connected to the connecting part 541. The connecting part 541 passes through the crossbeam 52. A limit block 542 is provided inside the crossbeam 52 corresponding to the connecting part. The limit block 542 is located on the outside of the crossbeam 52. One end of the connecting part 541 is fixedly connected to the limit block 542. The limit block 542 restricts the movement distance of the connecting part 541, making the extension and retraction of the gripper 54 more stable and reliable, and improving the clamping accuracy. A certain amount of material is wound around the connecting part 541. The elastic element 543 has two ends that abut against the clamping part 540 and the inner wall of the crossbeam 52, respectively. The elastic element 543 can provide a continuous elastic preload to the jaws 54, so that the jaws 54 have a certain buffering capacity when clamping the die casting, which can effectively absorb the impact during the clamping process and prevent the die casting from deforming due to excessive clamping force. At the same time, the elastic element 543 can enable the jaws 54 to automatically make adaptive adjustments when there are slight deviations in the size of the die casting, thereby improving the reliability of clamping and the compatibility with die castings of different specifications.

[0032] It should be further explained that the crossbeam 52 is provided with a through hole 521 and a limiting hole 522 corresponding to the connecting part 541. The connecting part 541 is sequentially inserted through the through hole 521 and the limiting hole 522. Through the cooperation of the through hole 521 and the limiting hole 522, the moving direction and moving range of the connecting part 541 can be guided and limited in a dual manner, making the extension and retraction of the gripper 54 more stable and precise, and avoiding the clamping position deviation caused by shaking or tilting. A connecting block 523 is also provided on the crossbeam 52 corresponding to the protective cover 511. The connecting block 523 is fixedly installed on the crossbeam 52, and the protective cover 511 is rotatably connected to the crossbeam 52 through the connecting block 523.

[0033] In addition, the protective cover 511 is L-shaped, and a baffle 514 is provided on the inner side of the protective cover 511. The baffle 514 is fixedly connected to the protective cover 511. The inner walls of both sides of the protective cover 511 are provided with sliding grooves 515 corresponding to the baffle 512. The sliding grooves 515 are arc-shaped. One end of the baffle 512 is installed inside the protective cover 511 via a slider 516. The slider 516 is slidably connected to the protective cover 511 through the sliding grooves 515. The baffle 512 and the slider 516 are connected by a rotating shaft 5121. The rotating shaft 5121 allows the baffle 512 to rotate at a certain angle during sliding. The other end of the plate 512 is connected to the protective cover 511 via a ball head pin 517. The cooperation between the ball head pin 517 and the rotating shaft 5121 allows the baffles 512 on both sides to move towards the center under the influence of the magnet 545 on the outside of the gripper 54 during the flipping of the protective assembly 51, initially forming a funnel shape. The ball head pin 517 provides multiple degrees of freedom of swing, so that the baffles 512 can automatically adjust their posture when moving towards the center, avoiding jamming or motion interference. The protective cover 511 and the gripper 54 are hinged together by a hinge rod 513, which is fixedly connected to the protective cover 511. A clearance groove 524 is provided on the crossbeam 52 corresponding to the hinge rod 513, which is a crucial supplement to ensure smooth operation of the linkage structure. It provides ample space for the hinge rod 513 to swing, effectively preventing mechanical interference between the hinge rod 513 and the crossbeam 52, ensuring that the flipping angle of the protective cover 511 meets design requirements, while reducing frictional wear between components and extending the overall service life of the structure. A hinge arm 544 is provided on the gripper 54 corresponding to the hinge rod 513. The hinge rod 513 and the hinge arm 544 are hinged together. The protective cover 511 is rotated around the hinge point toward the die-casting processing station 31 and the edge-cutting station 32. The linkage action of the protective cover 511 and the gripper 54 does not require additional drive components, which simplifies the overall structural design of the equipment and reduces manufacturing costs and later maintenance difficulties. Specifically, the hinged engagement of the hinge rod 513 and the hinge arm 544 can accurately transmit the movement trend of the gripper 54. When picking up or placing die castings or transferring them to the work station, the gripper 54 is squeezed, and then the engagement of the hinge arm 544 and the hinge rod 513 drives the protective cover 511 to rotate synchronously around the hinge point, ensuring that the protective cover 511 can automatically adjust the opening and closing angle according to the working state of the gripper 54 (such as picking up or placing die castings or transferring them to the work station). The bottom of both sides of the protective cover 511 is also provided with limiting protrusions 518. The limiting protrusions 518 are integrally formed with the protective cover 511. The limiting protrusions 518 are used to limit the rotation angle of the baffles 512 on both sides. By setting the limiting protrusions 518, the rotation range of the baffles 512 can be reliably limited, avoiding interference with other components due to excessive rotation during the flipping or closing process of the baffles 512, and ensuring that the movement of the baffles 512 always remains within the design range.

[0034] Furthermore, magnets 545 are provided on the outer side of the gripping part 540 of the gripper 54 and the bottom of the baffle 512. The magnets 545 at the bottom of the baffles 512 on both sides are attracted to the middle by the magnets 545 on the outer side of the gripper 54. Finally, the bottoms of the baffles 512 on both sides attract each other to form a bucket shape. The magnetic attraction method has the advantages of automatic reset, gentle movement and no mechanical wear. It can maintain stable performance in long-term high-frequency operation and improve the service life of the equipment. Under the action of magnetic force, the two side baffles 512 move towards the middle and close together, forming a bucket-shaped structure that can effectively intercept residual coolant or release agent, preventing it from splashing or dripping into the equipment and external environment during the transfer of die-cast parts, thus significantly improving the cleanliness and safety of the processing environment.

[0035] Furthermore, the adjustment mechanism 55 includes a mounting base 551, a lateral control component 552, and a lifting component 553; The lateral control assembly 552 includes a lateral drive motor 5521, a lead screw 5522, and a lead screw nut 5523. The lateral drive motor 5521 is fixedly mounted on the mounting base 551. The lead screw 5522 is connected to the output end of the lateral drive motor 5521 via a coupling 5524. The lead screw nut 5523 is sleeved on the lead screw 5522 and is connected to the crossbeam 52 via a lateral slide 5525. The lateral drive motor 5521 drives the lead screw 5522 to rotate, thereby causing the crossbeam 52 to move horizontally. The lifting assembly 553 includes a lifting cylinder 5531 and a lifting support plate 5532. The lifting cylinder 5531 is mounted on the mounting base 551, and the lifting support plate 5532 is mounted on the output end of the lifting cylinder 5531. The lifting support plate 5532 is fixedly connected to the output end of the lifting cylinder 5531. The lifting support plate 5532 is connected to both ends of the crossbeam 52. The lifting cylinder 5531 drives the lifting support plate 5532 to move vertically, thereby driving the crossbeam 52 to rise and fall vertically. The coordinated arrangement of the lateral control component 552 and the lifting component 553 enables the crossbeam 52 to move flexibly in both horizontal and vertical directions, achieving multi-dimensional position adjustment and meeting the material transfer requirements of different processing stations and die-cast parts of different specifications. The specific principles and structures are existing technologies, and this invention will not elaborate further.

[0036] It should be further noted that the adjustment mechanism 55 also includes a longitudinal control component 554, which connects the crossbeam 52 and the lifting support plate 5532. The longitudinal control component 554 includes a longitudinal cylinder 5541, a longitudinal slider 5542, and a longitudinal slide rail 5543; The longitudinal cylinder 5541 and the longitudinal slide rail 5543 are both fixedly installed on the top of the lifting support plate 5532; Two sets of longitudinal sliders 5542 are provided and are corresponding to the crossbeam 52. The longitudinal sliders 5542 are slidably mounted on the longitudinal slide rail 5543. The longitudinal sliders 5542 are connected to the crossbeam 52 through guide sliders 5544. A guide slide rail 5545 is provided on the crossbeam 52 corresponding to the guide sliders 5544. By adding a longitudinal control component 554, the crossbeam 52 gains independent adjustment capability in the longitudinal direction. Combined with the transverse control component 552 and the lifting component 553, the crossbeam 52 can move flexibly in three-dimensional space, significantly improving the spatial adjustment range and adaptability of the material transfer device. It can meet the material transfer requirements of different workstation layouts and die-cast parts of different specifications. The cooperation between the longitudinal slider 5542 and the longitudinal slide rail 5543 provides stable guiding support for the longitudinal movement of the crossbeam 52, ensuring accurate and smooth movement trajectory. The setting of the guide slider 5544 and the guide slide rail 5545 further enhances the movement accuracy and structural rigidity of the crossbeam 52, enabling the crossbeam 52 to maintain good stability when carrying die-cast parts. The output end of the longitudinal cylinder 5541 is connected to the guide slider 5544 on one side. The longitudinal slider 5542 is connected to the guide slider 5544 via a connecting plate 5546. The connecting plate 5546 is provided with teeth 5547. The connecting plates 5546 on both sides are connected by a transmission gear 5548. The transmission gear 5548 is fixedly installed on the lifting support plate 5532. By providing teeth 5547 on the connecting plate 5546 and using the transmission gear 5548 to achieve synchronous transmission of the connecting plates 5546 on both sides, the longitudinal cylinder 5541 on one side can drive the crossbeams 52 on both sides to move synchronously in opposite directions or in the same direction. This not only simplifies the drive structure and reduces the control complexity and equipment cost, but also ensures the high synchronicity of the movement of the crossbeams 52 on both sides, avoiding tilting or falling of the die-casting part due to inconsistent movement on both sides, and effectively improving the reliability and safety of the material transfer process.

[0037] As an improvement, the spraying assembly 4 includes a slide assembly 41, a pneumatic nozzle 42, and a spray pipe 43. The spray pipe 43 is mounted on the slide assembly 41, and the pneumatic nozzle 42 is connected to the spray pipe 43. The slide assembly 41 drives the spray pipe 43 to move towards the forging device 3. The pneumatic nozzle 42 is finally located at the spraying station 33 between the die-casting processing stations 31. During the process of switching processing stations for die-casting parts, the release agent is sprayed on the upper and lower molds of the die-casting processing station 31, and the die-casting parts located between adjacent processing stations are protected, ensuring that the release agent can act directly and accurately inside the mold and avoid affecting the surface of the die-casting parts. Meanwhile, the movable design of the slide assembly 41 enables the pneumatic nozzle 42 to quickly reach its position at the appropriate time without interfering with the normal transfer and processing of the die-cast parts, thus improving the coordination of the overall production rhythm. The pneumatic nozzle 42 adopts a nozzle structure, which enables the release agent to be sprayed out in a uniform mist form, ensuring that the release agent forms a uniform covering layer on the mold surface, which not only ensures a good release effect, but also avoids the waste and excessive accumulation of the release agent.

[0038] Working principle: First, the medium-frequency furnace 1 heats the die-casting part to reach a suitable forging temperature. Then, the transfer device 2 transports the heated die-casting part to the input end of the forging device 3. The transfer device 5 moves the die-casting part sequentially to the die-casting processing station 31 and the trimming station 32 for die-casting and trimming. Before the die-casting part enters the die-casting processing station 31, the spraying component 4 sprays a release agent onto the mold. During the spraying of the release agent, the protective component 51 flips with the movement of the transfer device 5, forming a semi-enclosed space together with the baffles on both sides to prevent the release agent from splashing to both sides. Finally, the forging part after die-casting or trimming is transported by the transfer device 5 to the next process or the finished product area.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
