[0002] Against the backdrop of the rapid development of the automotive manufacturing industry, the production quality and efficiency of auto parts directly impact vehicle performance and corporate competitiveness. With increasing demands for lightweight, safe, and other performance features, sheet metal parts, due to their lightweight and high strength, are increasingly being used in automotive structural parts, panels, and other fields. This is driving continued demand for high-precision, high-quality sheet metal castings.

[0003] However, existing automotive parts casting equipment faces several technical bottlenecks when processing sheet metal castings. For one thing, traditional casting equipment has a low degree of automation, with the entire process, from casting to transporting to cooling, largely relying on manual operations.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0029] Example 1, please refer to Figure 1, the automotive parts casting equipment provided in this embodiment is mainly dedicated to the processing of sheet metal castings, and is composed of a casting main unit group 1, a casting turnover equipment group 2, and a cooling and conveying unit group 3. Among them, the casting main unit group 1 includes a casting operation platform 11, a forming die 12, and a casting pressing assembly 13. The forming die 12 is firmly installed on the upper surface of the casting operation platform 11, and the casting pressing assembly 13 is arranged vertically above the casting operation platform 11, and can perform precise pressing operations on the forming die 12 to meet the forming requirements of sheet metal castings.

[0030] The casting turnover equipment group 2 is arranged at the rear station of the casting main unit group 1, and includes a turnover workbench 21, an upper plate surface rolling device 22, a lifting module device 23, a displacement module device 24, and a casting grabbing manipulator 25. The front end of the turnover workbench 21 is closely connected to the casting operation platform 11 to ensure the smooth transfer of sheet metal castings; the upper plate surface rolling device 22 is fixed at the output end of the turnover workbench 21 and can perform rolling treatment on the upper plate surface of the sheet metal castings; the displacement module device 24 is installed at the lifting execution end of the lifting module device 23, and the casting grabbing manipulator 25 is fixed on the mobile end of the displacement module device 24. Driven by the displacement module device 24, the casting grabbing manipulator 25 can shuttle back and forth between the forming die 12 and the turnover workbench 21 to realize the automated transfer process of sheet metal castings.

[0031] The cooling and conveying unit group 3 is located at the rear station of the casting turnover equipment group 2, and is composed of a cooling box 31, a conveyor frame 32, a first transfer workbench 33, a cooling air box 34, a lower plate surface rolling device 35, a buffer storage area 36, and a second transfer workbench 37. The input end of the cooling box 31 is seamlessly docked with the turnover workbench 21, and the conveyor frame 32 is fixed at the output end of the cooling box 31; the first transfer workbench 33 is installed inside the cooling box 31, and the cooling air box 34 is installed on the top of the inner compartment of the cooling box 31; the lower plate surface rolling device 35 is located at the connection part between the first transfer workbench 33 and the second transfer workbench 37, the buffer storage area 36 is located at the end of the conveyor frame 32, and the second transfer workbench 37 is installed on the conveyor frame 32, its input end is connected to the first transfer workbench 33, and the output end extends to the buffer storage area 36. The first transfer workbench 33 is responsible for receiving the sheet metal castings conveyed by the turnover workbench 21. After being cooled by the cooling air box 34, it is transferred to the second transfer workbench 37 by means of the lower plate surface rolling device 35, and finally conveyed to the buffer storage area 36 for temporary storage.

[0032] In terms of the working process, in the casting main unit 1, first, the sheet metal casting material is placed into the forming die 12, and the casting pressing assembly 13 applies pressure to the forming die 12 to form the sheet metal material into the required parts. The formed sheet metal casting is grabbed and transferred to the turnover workbench 21 by the casting grabbing manipulator 25 under the coordinated operation of the displacement module device 24 and the lifting module device 23, and is rolled by the upper plate rolling device 22 to level the upper plate of the sheet metal casting. Subsequently, the sheet metal casting is conveyed to the cooling conveyor unit 3. In the cooling box 31, the first transfer workbench 33 receives the casting, and the top array of cooling air boxes 34 uniformly blows air from above to quickly cool the sheet metal casting. The cooled sheet metal casting passes through the lower plate rolling device 35 to roll and shape the lower plate, and then is conveyed to the buffer storage area 36 by the second transfer workbench 37 to wait for subsequent processing.

[0033] In this embodiment, the equipment is designed according to the characteristics of sheet metal castings. The casting main unit 1 applies pressure to the forming die 12 through the casting pressing assembly 13 to form the sheet metal material using pressure, meeting the shape requirements of the sheet metal castings; the casting grabbing manipulator 25, the displacement module device 24, and the lifting module device 23 in the casting turnover equipment group 2 constitute an automated transfer system. Based on the mechanical transmission principle, precise grabbing and transfer of the sheet metal castings are achieved. The upper plate rolling device 22 performs preliminary shaping on the upper plate of the sheet metal casting through the rolling action; the cooling conveyor unit 3 uses the array of cooling air boxes 34 to blow air to achieve rapid and uniform cooling of the sheet metal castings. The lower plate rolling device 35 rolls and shapes the sheet metal casting again to ensure the flatness and dimensional accuracy of the sheet metal casting. Each component works together to complete the entire process of sheet metal casting from casting to cooling and temporary storage.

[0034] In this embodiment, the rolling devices designed for sheet metal castings, the upper plate rolling device 22 and the lower plate rolling device 35 respectively process the upper and lower plates of the sheet metal casting, effectively improving the flatness and surface quality of the sheet metal casting and reducing the workload of the later shaping process; the array installation of the cooling air boxes 34 can achieve uniform cooling of the sheet metal casting, avoiding deformation problems caused by uneven cooling and ensuring the dimensional accuracy of the sheet metal casting; the equipment has a high degree of automation, and the entire production process from casting, transfer to cooling and temporary storage is automated, making the whole production process more efficient and orderly, and helping to improve the production capacity and market competitiveness of the enterprise's sheet metal castings.

[0035] Embodiment 2, based on the content described in the above embodiment, please refer to Figure 1 and Figure 2 , for the specific implementation structure of the casting main unit 1, this embodiment is designed as follows: The casting operation platform 11 includes an equipment support base 111 fixedly installed on the ground workstation and serving as the overall support structure, and an ejector frame 112 vertically mounted on the upper surface of the equipment support base 111. The molding die 12 is securely mounted on the top working surface of the ejector frame 112 by bolts. The casting pressing assembly 13 includes a bottom support structure 131 whose base is fixed to the ground behind the equipment support base 111 by anchor bolts, and a guide positioning frame 132 vertically mounted on the top platform of the bottom support structure 131 and equipped with a linear guide assembly. , a pressing support top frame 133 is vertically slidably connected to the guide positioning frame 132 through a guide rail slider assembly, and a mold clamping pressure chamber 134 is formed on the bottom pressure-bearing surface of the pressing support top frame 133 and is internally equipped with a hydraulic pressure device and a temperature control system. The pressing support top frame 133 can perform vertical reciprocating motion along the guide positioning frame 132. When it moves to the bottom dead point, the mold clamping pressure chamber 134 and the forming mold 12 form a closed cavity. The ejection mechanism built into the ejection device frame 112 ejects the molded casting to a preset grabbing position when the mold is opened.

[0036] During operation, the sheet metal casting material is first placed in the forming mold 12. The pressing support frame 133 slides vertically downward along the linear guide assembly of the guide positioning frame 132. When it reaches the bottom dead center, the mold clamping pressure chamber 134 and the forming mold 12 form a closed cavity. The hydraulic pressure device in the mold clamping pressure chamber 134 applies pressure to the sheet metal material to form it. At the same time, the temperature control system maintains the appropriate temperature in the cavity to ensure the quality of the sheet metal casting. After molding is completed, the pressing support frame 133 slides upward to open the mold. The ejection mechanism built into the ejection device frame 112 ejects the formed sheet metal casting to a preset grabbing position, facilitating the subsequent transfer operation of the casting grabbing robot 25.

[0037] In view of the fact that sheet metal castings require precise pressure and temperature control, the casting main unit 1 provides stable and adjustable pressure through the hydraulic pressure device in the mold pressure chamber 134 to meet the molding pressure requirements of different sheet metal castings. The temperature control system ensures that the sheet metal material is molded at a suitable temperature to avoid casting defects caused by temperature problems. The sliding connection structure of the pressing support top frame 133 and the guide positioning frame 132 ensures the stability and accuracy of the pressing process and can accurately control the mold closing and opening actions. The ejection mechanism built into the ejection device frame 112 is based on the principle of mechanical transmission. After the mold is opened, the sheet metal casting is accurately ejected, creating conditions for subsequent automated transportation. All parts work together to achieve efficient and high-quality casting of sheet metal castings.

[0038] Example 3, based on the content of the above example, please refer to Figure 1 、 Figure 3 and Figure 4, for the specific implementation structure of the casting turnover equipment group 2, this embodiment is designed as follows: The turnover workbench 21 is composed of support columns 211, a tabletop main body 212, a support frame 215, and an extension part 214. The support columns 211 are fixed to the ground foundation as vertical support members, and the tabletop main body 212 is bolted to the top of the support columns 211. Its upper surface adopts an inclined and curved structure to form a ramp tabletop 213, and the inclination angle meets the process requirements for the self-sliding of castings; the support frame 215 is horizontally welded to the middle side edge of the support columns 211 for fixing the lifting module device 23; the extension part 214 extends longitudinally from the rear end of the support columns 211, and its end is hermetically docked with the input port of the cooling box 31 through a flange connection structure to ensure that a continuous conveying channel is formed between the turnover workbench 21 and the cooling box 31.

[0039] The lifting module device 23 includes a lifting machine frame 231, a lifting base 232, and a lifting screw rod assembly 233. The lifting machine frame 231 is fixed to the bearing plane of the support frame 215 with anchor bolts, and the lifting base 232 is vertically slidably connected to the lifting machine frame 231 through the lifting screw rod assembly 233. The lifting screw rod assembly 233 consists of a servo motor and a ball screw. The nut seat of the ball screw is rigidly connected to the lifting base 232, and the servo motor drives the ball screw to rotate through a coupling to achieve precise positioning of the lifting base 232. The displacement module device 24 works in coordination with the casting grasping manipulator 25. In the displacement module device 24, the pushing module 241 adopts a rodless cylinder structure, and the cylinder body is fixed to the front end face of the lifting base 232; the manipulator sliding guide rail 242 is composed of two parallel precision linear guide rails, and its guide rail base is rigidly connected to the slider of the pushing module 241; the positioning support rod 243 is arranged at the terminal limit of the manipulator sliding guide rail 242 and is equipped with a coordinate sensor 244 to achieve precise positioning.

[0040] The casting grasping manipulator 25 includes a sliding base 251, an outer support claw arm 252, and a vacuum suction cup 253. The sliding base 251 is slidably connected to the manipulator sliding guide rail 242 through a linear bearing, the outer support claw arm 252 is pivotally connected to the sliding base 251 through a hinge mechanism, and the vacuum suction cup 253 is installed at the end of the outer support claw arm 252 for grasping sheet metal castings.

[0041] During operation, after the sheet metal casting formed by the casting main unit 1 is ejected to a preset position, the vacuum suction cup 253 of the casting gripping manipulator 25 moves above the casting under the drive of the lifting module device 23 and the displacement module device 24, and the vacuum suction cup 253 adsorbs the sheet metal casting. Subsequently, the pushing module 241 of the displacement module device 24 drives the manipulator sliding guide rail 242 and the casting gripping manipulator 25 to move, and transfers the sheet metal casting to the ramp table 213 of the turnover workbench 21. The casting slides along the ramp table 213 to the first transfer workbench 33 by its own gravity and enters the cooling conveyor unit 3 for subsequent cooling treatment.

[0042] Based on the principle of a servo motor driving a ball screw, the lifting module device 23 can accurately control the position of the lifting base 232, enabling the casting gripping manipulator 25 to accurately reach the sheet metal casting gripping position. The rodless cylinder structure of the displacement module device 24 combined with a precision linear guide ensures the stable and rapid movement of the casting gripping manipulator 25 in the horizontal direction, and the positioning support rod 243 and the coordinate sensor 244 achieve precise positioning. The casting gripping manipulator 25 uses a vacuum suction cup 253, and based on the principle of vacuum adsorption, it can stably grip and place the casting without damaging the surface of the sheet metal casting. The entire casting turnover equipment group 2 realizes the efficient and damage-free transfer of the sheet metal casting through the coordinated operation of each component.

[0043] Embodiment 4. Based on the content described in the above embodiments, please refer to Figure 1 、 Figure 3 and Figure 5 , for the specific implementation structure of the upper plate rolling device 22, the design of this embodiment is as follows: The upper plate rolling device 22 mainly consists of components such as the side wing plate parts 222, the pushing mechanism 223, the side wing frame 224, the side wing slide rail 225, the lower pressing frame 227, the pressing roller frame 228, and the micro pressing roller 229. The side wing plate parts 222 are detachably and fixedly installed on the tail side edge of the table main body 212 through the side connecting parts 221, and the side wing support columns 226 are vertically installed above them; the pushing mechanism 223 adopts a double-acting hydraulic cylinder structure, and the cylinder body is fixedly connected by a flange to the bottom mounting seat of the side wing support column 226; the side wing frames 224 are symmetrically distributed at the two transverse ends of the lower pressing frame 227, and each side wing frame 224 is equipped with a double-row side wing slide rail 225, and the side wing slide rail 225 is in sliding fit with the eight-shaped guide groove in the inner cavity of the side wing support column 226 to form a space inclined guiding mechanism.

[0044] The downward pressure frame 227 serves as the main working component, and its two ends are rigidly connected to the flank frames 224 by bolts; the roller frame 228 is suspended and installed at the bottom of the downward pressure frame 227 by means of an elastic shock-absorbing component, and micro rollers 229 are arranged at equal intervals inside. The surface of the micro rollers 229 is coated with a wear-resistant rubber layer, and its arrangement density can meet the requirements of full coverage rolling of the casting surface; the inclination angle of the flank slide rail 225 is the same as the slope of the slope table surface 213 of the table body 212; mechanical limit blocks and hydraulic buffers are provided at the end point of the stroke of the pushing mechanism 223.

[0045] The working process is as follows: When the sheet metal casting manipulator 25 transfers the sheet metal casting to the slope table surface 213 of the turnover workbench 21, the double-acting hydraulic cylinder of the pushing mechanism 223 is started, and the flank frame 224 and the downward pressure frame 227 are pushed to move downward along the flank slide rail 225, so that the micro rollers 229 in the roller frame 228 are in contact with the upper plate surface of the sheet metal casting. As the sheet metal casting slides down on the slope table surface 213 by gravity, the micro rollers 229 perform continuous rolling treatment on it to complete the flattening and shaping of the upper plate surface. After the rolling is completed, the double-acting hydraulic cylinder contracts, driving the downward pressure frame 227 and the roller frame 228 to move upward and reset, waiting for the next rolling operation.

[0046] In view of the characteristics of the thin and easily deformable sheet metal casting, the upper plate surface rolling device 22 uses an elastic shock-absorbing component to suspend and install the roller frame 228, which can effectively buffer the impact force during the rolling process and avoid excessive extrusion deformation of the sheet metal casting. The double-acting hydraulic cylinder of the pushing mechanism 223 can provide stable and controllable pressure to ensure that the micro rollers 229 apply an appropriate rolling pressure to the upper plate surface of the sheet metal casting. The space inclination guiding mechanism composed of the flank slide rail 225 and the inner cavity guide groove of the flank support column 226, in cooperation with the slope of the slope table surface 213, enables the micro rollers 229 to always maintain good contact with the upper plate surface of the sheet metal casting during the rolling process, realizing uniform rolling. The wear-resistant rubber layer on the surface of the micro rollers 229 can not only ensure the rolling effect but also prevent scratching the surface of the sheet metal casting. The mechanical limit blocks and hydraulic buffers at the end point of the stroke of the pushing mechanism 223 ensure the safety and stability of the downward pressure and reset processes.

[0047] Example 5, based on the content described in the above example, please refer to Figure 1 and Figure 6 , in this example, the specific implementation structure of the lower plate surface rolling device 35 is designed, and this device has both the functions of surface support and pressing and secondary air cooling.

[0048] The lower panel rolling device 35 is mainly composed of a rolling frame 351 and a secondary cooling box 352. At the top of the rolling frame 351, there is a supporting working surface 353, along which two parallel rolling opening grooves 354 are longitudinally opened. Part of the roller body of the press-fitting roller group 355 configured inside is exposed above the supporting working surface 353 through the rolling opening grooves 354. At the top of the secondary cooling box 352, there is an air outlet 356, and the geometric center thereof corresponds to the vertical projection of the longitudinal central axis of the rolling opening groove 354. In addition, mounting shaft seats 385 are provided at both ends of the rolling frame 351, and are rotatably connected to the conveyor frame 32 through positioning bearings 381. The outer ring of one side positioning bearing 381 is connected to a swing block 382, and the drive shaft body 384 at the bottom of the conveyor frame 32 is drivingly connected to the swing block 382 through a transmission connecting rod 383, so as to adjust the docking angle between the rolling frame 351 and the second transfer workbench 37. On both sides of the air outlet 356, there are side wing air guiding fences 357, and the air guiding direction thereof points to the docking gap between the rolling frame 351 and the second transfer workbench 37, and the unfolding angle is adapted to the air flow diffusion angle of the air outlet 356.

[0049] The working process of the lower panel rolling device 35 is as follows: When the sheet metal casting is conveyed to the supporting working surface 353 of the rolling frame 351 through the first transfer workbench 33, the press-fitting roller group 355 presses the lower panel of the sheet metal casting through the rolling opening grooves 354. At the same time, the secondary cooling box 352 is started, and cold air is sent out from the bottom up through the air outlet 356, forming a secondary air cooling effect with the air cooling from the cooling box body 31 from top to bottom, and cooling the sheet metal casting in all directions. During the cooling process, the side wing air guiding fences 357 guide the cold air to the gap between the rolling frame 351 and the second transfer workbench 37, ensuring that parts such as the edges of the sheet metal casting can also be fully cooled. According to the specifications and conveying requirements of the sheet metal casting, the drive shaft body 384 can be rotated, and the swing block 382 can be driven through the transmission connecting rod 383 to adjust the docking angle between the rolling frame 351 and the second transfer workbench 37, so that the sheet metal casting can be smoothly transferred to the second transfer workbench 37.

[0050] The lower panel rolling device 35 adopts a dual-function design. The press-fitting roller group 355 applies pressure to the lower panel of the sheet metal casting through the rolling opening grooves 354 for shaping, and improves the flatness and shape accuracy of the sheet metal casting by using the rolling principle. In the secondary air cooling measure, the secondary cooling box 352 sends air from the bottom up, forming a convection with the air cooling from the cooling box body 31 from top to bottom, enhancing the cooling effect, accelerating the cooling speed of the sheet metal casting, and avoiding deformation caused by uneven cooling. Through the adjustment mechanism composed of the positioning bearing 381, the swing block 382, the drive shaft body 384 and the transmission connecting rod 383, the angle of the rolling frame 351 can be flexibly adjusted to adapt to the conveying requirements of sheet metal castings of different specifications. The side wing air guiding fences 357 guide the cold air to cover the key areas according to the aerodynamic principle, optimize the cooling air flow distribution, and improve the cooling efficiency and uniformity.

[0051] In this embodiment, the lower plate surface rolling device 35 combines rolling shaping with secondary air cooling. While shaping the lower plate surface of the sheet metal casting, it achieves efficient cooling, reduces the process connection time, and improves production efficiency. The design of the docking angle between the adjustable rolling frame 351 and the second transfer workbench 37 can adapt to the transportation of sheet metal castings of various specifications, enhancing the versatility and flexibility of the equipment. The secondary air cooling measure and the setting of the side wing air guide bar 357 ensure the uniformity and rapidity of the cooling of the sheet metal casting, effectively reducing the risk of deformation of the casting caused by cooling problems and improving the quality of the casting. The rolling and shaping function of the pressing roller group 355 further optimizes the surface flatness and shape accuracy of the sheet metal casting, meets the high-precision production requirements of automotive parts, helps to improve the competitiveness of the enterprise's products, and reduces production costs.
