[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.

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0074] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0075] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0076] For example 1, please refer to Figure 1The automotive parts casting equipment provided in this embodiment is primarily dedicated to the processing of sheet metal castings and comprises a main casting unit 1, a casting turnover equipment unit 2, and a cooling conveyor unit 3. The main casting unit 1 includes a casting platform 11, a forming die 12, and a casting press assembly 13. The forming die 12 is securely mounted on the upper surface of the casting platform 11. The casting press assembly 13 is positioned vertically above the casting platform 11 and is capable of performing precise pressing operations on the forming die 12 to meet the molding requirements of sheet metal castings.

[0077] The casting turnover equipment group 2 is arranged at the rear station of the main casting unit 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 robot 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 to the output end of the turnover workbench 21 and can roll the upper plate surface of the sheet metal casting; the displacement module device 24 is installed at the lifting execution end of the lifting module device 23, and the casting grabbing robot 25 is fixed to the moving end of the displacement module device 24. Driven by the displacement module device 24, the casting grabbing robot 25 can shuttle back and forth between the forming mold 12 and the turnover workbench 21, realizing the automated transfer process of sheet metal castings.

[0078] The cooling conveyor unit 3 is located at the rear station of the casting turnover equipment group 2, and consists of a cooling box 31, a conveyor frame 32, a first conveying workbench 33, a cooling air box 34, a lower plate surface rolling device 35, a buffer storage area 36 and a second conveying workbench 37. The input end of the cooling box 31 is seamlessly connected to the turnover workbench 21, and the conveyor frame 32 is fixed to the output end of the cooling box 31; the first conveying 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 at the junction of the first conveying workbench 33 and the second conveying workbench 37, the buffer storage area 36 is located at the end of the conveyor frame 32, and the second conveying workbench 37 is installed on the conveyor frame 32, with its input end connected to the first conveying workbench 33 and its output end extending to the buffer storage area 36. The first conveying 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, the sheet metal castings are transferred to the second conveying workbench 37 by the lower plate rolling device 35 and finally conveyed to the buffer storage area 36 for temporary storage.

[0079] In terms of the working process, in the casting main unit 1, the sheet metal casting material is first placed in the forming mold 12, and the casting pressing assembly 13 applies pressure to the forming mold 12 to form the sheet metal material into the required parts. The formed sheet metal casting is grabbed by the casting grasping robot 25 and transferred to the turnover workbench 21 under the coordinated operation of the displacement module device 24 and the lifting module device 23. It is rolled by the upper plate surface rolling device 22 to smooth the upper plate surface of the sheet metal casting. Subsequently, the sheet metal casting is transported to the cooling conveyor unit 3. In the cooling box 31, the first conveying workbench 33 receives the casting, and the top array of cooling air boxes 34 evenly supplies air from above to quickly cool the sheet metal casting. The cooled sheet metal casting passes through the lower plate surface rolling device 35 to roll and shape the lower plate surface, and then is transported to the buffer storage area 36 by the second conveying workbench 37 to await subsequent processing.

[0080] In this embodiment, the equipment is designed based on the characteristics of sheet metal castings. The main casting unit 1 applies pressure to the forming die 12 through the casting pressing assembly 13, and uses pressure to shape the sheet metal material to meet the shape requirements of the sheet metal casting; the casting grasping 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 principle of mechanical transmission, it can achieve accurate grasping and transfer of sheet metal castings. The upper plate surface rolling device 22 performs preliminary shaping on the upper plate surface of the sheet metal casting through rolling action; the cooling conveyor unit 3 uses an array of cooling bellows 34 to supply air to achieve rapid and uniform cooling of the sheet metal casting. The lower plate surface rolling device 35 rolls and shapes the sheet metal casting again to ensure the flatness and dimensional accuracy of the sheet metal casting. All components work together to complete the complete process of sheet metal casting from casting to cooling and temporary storage.

[0081] The rolling device designed for sheet metal castings in this embodiment, the upper plate rolling device 22 and the lower plate rolling device 35 respectively process the upper and lower plate surfaces of the sheet metal castings, effectively improving the flatness and surface quality of the sheet metal castings, and reducing the workload of the subsequent shaping process; the array installation of the cooling bellows 34 can achieve uniform cooling of the sheet metal castings, avoid deformation problems caused by uneven cooling, and ensure the dimensional accuracy of the sheet metal castings; the equipment has a high degree of automation, and automated operations are achieved from casting, transportation to cooling and temporary storage, making the entire production process more efficient and orderly, which helps to improve the company's sheet metal casting production capacity and market competitiveness.

[0082] Example 2: Based on the above example, please refer to Figure 1 and Figure 2 Regarding the specific implementation structure of the casting main unit 1, this embodiment is designed as follows:

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Example 3, based on the content of the above example, please refer to Figure 1 、 Figure 3 and Figure 4Regarding the specific implementation structure of the casting turnover equipment group 2, this embodiment is designed as follows:

[0087] The turnover workbench 21 consists of a support column 211, a table body 212, a support frame 215, and an extension 214. The support column 211 is fixed to the ground foundation as a vertical support member. The table body 212 is bolted to the top of the support column 211. Its upper surface adopts an inclined curved structure to form a sloped table 213. The inclination angle meets the requirements of the casting self-sliding process. The support frame 215 is horizontally welded to the side edge of the middle part of the support column 211 and is used to fix the lifting module 23. The extension 214 extends longitudinally from the rear end of the support column 211. The end is sealed and docked with the input port of the cooling box 31 through a flange connection structure, ensuring that the turnover workbench 21 and the cooling box 31 form a continuous conveying channel.

[0088] The lifting module 23 comprises a lifting frame 231, a lifting base 232, and a lifting screw assembly 233. The lifting frame 231 is fixed to the load-bearing surface of the support frame 215 with anchor bolts. The lifting base 232 is vertically slidably connected to the lifting frame 231 via the lifting screw assembly 233. The lifting screw assembly 233 consists of a servo motor and a ball screw. The ball screw's nut is rigidly connected to the lifting base 232. The servo motor drives the ball screw through a coupling to achieve precise positioning of the lifting base 232.

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 robot 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 robot sliding guide rail 242, and is equipped with a coordinate sensor 244 to achieve precise positioning.

[0089] The casting gripper 25 comprises 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's sliding guide rail 242 via a linear bearing. The outer support claw arm 252 is hinged to the sliding base 251 for opening and closing. The vacuum suction cup 253 is mounted at the end of the outer support claw arm 252 and is used to grip sheet metal castings.

[0090] When the work is done, the sheet metal casting shaped by the casting host group 1 is ejected to the preset position, and the vacuum suction cup 253 of the casting grabbing manipulator 25 is driven by the lifting module device 23 and the displacement module device 24 to move to the top of the casting, 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 grabbing manipulator 25 to move, and the sheet metal casting is transported to the inclined ramp table 213 of the turnover workbench 21, and the casting relies on its own gravity to slide along the inclined ramp table 213 to the first conveying workbench 33, and enters the cooling conveyor group 3 for subsequent cooling treatment.

[0091] The lifting module device 23 can accurately control the position of the lifting base 232 based on the principle of servo motor driving ball screw, so that the casting grabbing manipulator 25 accurately reaches the sheet metal casting grabbing position; the rodless cylinder structure of the displacement module device 24 combines with the precision linear guide rail to ensure that the casting grabbing manipulator 25 moves stably and quickly in the horizontal direction, and the positioning support 243 and the coordinate sensor 244 realize accurate positioning. The casting grabbing manipulator 25 adopts the vacuum suction cup 253, which can stably grab and place the casting without damaging the surface of the sheet metal casting by using the vacuum adsorption principle. The entire casting turnover equipment group 2 realizes efficient and non-destructive transfer of sheet metal castings through the cooperative operation of each component.

The surface of the micro pressing roller 229 is covered with a wear-resistant rubber layer, and the arrangement density can meet the full-coverage roller pressing requirement of the surface of the castings; the inclination angle of the side wing slide rail 225 is consistent with the slope of the inclined ramp 213 of the table body 212; the mechanical limiting block and the hydraulic buffer are arranged at the stroke end of the pushing mechanism 223.

[0095] The working process is as follows: after the casting grabbing manipulator 25 transfers the sheet metal casting to the inclined ramp 213 of the turnover workbench 21, the double-acting hydraulic cylinder of the pushing mechanism 223 is started to push the side wing frame 224 and the lower pressing frame 227 to move downward along the side wing slide rail 225, so that the micro pressing rollers 229 in the pressing roller frame 228 are in contact with the upper plate surface of the sheet metal casting. As the sheet metal casting slides downward on the inclined ramp 213 by relying on gravity, the micro pressing rollers 229 continuously roll the sheet metal casting to complete the flattening and shaping of the upper plate surface. After the roller pressing is completed, the double-acting hydraulic cylinder is retracted to drive the lower pressing frame 227 and the pressing roller frame 228 to move upward and reset, waiting for the next roller pressing operation.

[0096] In view of the characteristics of thinness and easy deformation of the sheet metal casting, the elastic damping assembly is used to suspend the installation of the pressing roller frame 228, which can effectively buffer the impact force in the roller pressing 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 pressing rollers 229 apply appropriate roller pressing force to the upper plate surface of the sheet metal casting. The inclined guide mechanism formed by the space between the side wing slide rail 225 and the inner cavity guide groove of the side wing support column 226 cooperates with the slope of the inclined ramp 213 to ensure that the micro pressing rollers 229 always well adhere to the upper plate surface of the sheet metal casting during the roller pressing process, achieving uniform roller pressing. The wear-resistant rubber layer on the surface of the micro pressing roller 229 can not only ensure the roller pressing effect but also prevent scratching the surface of the sheet metal casting. The mechanical limiting block and the hydraulic buffer at the stroke end of the pushing mechanism 223 ensure the safety and stability of the pressing and resetting processes.

[0097] In the above embodiments, please refer to Figure 1 and Figure 6 , the specific implementation structure of the lower plate surface roller pressing device 35 is designed, which has the functions of surface supporting and pressing and two-stage air cooling.

[0098] The lower plate surface roller pressing device 35 is mainly composed of a roller pressing frame 351 and a secondary cooling box 352. The roller pressing frame 351 is provided with a support working surface 353 at the top, two parallel roller pressing opening slots 354 are longitudinally formed on the support working surface 353, and part of the roller bodies of the pressing roller group 355 arranged inside the roller pressing frame 351 are exposed above the support working surface 353 through the roller pressing opening slots 354. The secondary cooling box 352 is provided with an air outlet 356 at the top, and the geometric center of the air outlet 356 is vertically projected to correspond to the longitudinal center axis of the roller pressing opening slots 354. In addition, the roller pressing frame 351 is provided with mounting shaft seats 385 at both ends, which 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 body 382, and the drive shaft body 384 at the bottom of the conveyor frame 32 is drivingly connected to the swing block body 382 through a transmission connecting rod 383 to adjust the included angle of the roller pressing frame 351 and the second conveying workbench 37. The air outlet 356 is provided with side wing wind guide fences 357 on both sides, and the air guide direction of the side wing wind guide fences 357 is directed to the gap between the roller pressing frame 351 and the second conveying workbench 37, and the expansion angle is adapted to the airflow diffusion angle of the air outlet 356.

[0099] The working process of the lower plate surface roller pressing device 35 is as follows: when the metal sheet casting is conveyed to the support working surface 353 of the roller pressing frame 351 through the first conveying workbench 33, the pressing roller group 355 presses the lower plate surface of the metal sheet casting through the roller pressing opening slots 354. At the same time, the secondary cooling box 352 is started, and cold air is sent out from bottom to top through the air outlet 356, and the air cooling from top to bottom of the cooling box body 31 forms a secondary air cooling effect, so that the metal sheet casting is cooled in all directions. In the cooling process, the side wing wind guide fences 357 guide the cold air to the gap between the roller pressing frame 351 and the second conveying workbench 37, so that the edge and other parts of the metal sheet casting can also be fully cooled. According to the specifications and conveying requirements of the metal sheet casting, the drive shaft body 384 can be rotated to drive the swing block body 382 through the transmission connecting rod 383 to adjust the included angle of the roller pressing frame 351 and the second conveying workbench 37, so that the metal sheet casting can be smoothly transferred to the second conveying workbench 37.

[0100] The lower plate surface roller pressing device 35 adopts a dual-function design. The pressing roller group 355 applies pressure to the lower plate surface of the metal sheet casting through the roller pressing opening slots 354 to perform shaping treatment, and improves the flatness and shape accuracy of the metal sheet casting by using the principle of roller pressing. In the secondary air cooling measure, the secondary cooling box 352 sends air from bottom to top, and the air cooling from top to bottom of the cooling box body 31 forms a convection to enhance the cooling effect, accelerate the cooling speed of the metal sheet casting, and avoid deformation caused by uneven cooling. The adjusting mechanism composed of the positioning bearing 381, the swing block body 382, the drive shaft body 384 and the transmission connecting rod 383 realizes flexible adjustment of the angle of the roller pressing frame 351 to adapt to the conveying requirements of metal sheet castings of different specifications. According to the principle of aerodynamics, the side wing wind guide fences 357 guide the cold air to cover the key areas, optimize the distribution of cooling air flow, and improve the cooling efficiency and uniformity.

[0101] The lower plate roller pressing device 35 of the embodiment combines roller pressing and two-stage air cooling, shapes the lower plate of the sheet metal casting, realizes efficient cooling, reduces the process connection time, and improves the production efficiency; the adjustable roller pressing rack 351 and the second conveying workbench 37 are designed to be connected at an adjustable angle, which can adapt to the conveying of sheet metal castings of various specifications, and enhances the versatility and flexibility of the equipment; the two-stage air cooling measures and the side wing wind guide fence 357 ensure the uniformity and rapidity of the cooling of the sheet metal casting, effectively reduce the risk of deformation of the casting due to cooling problems, and improve the casting quality; the roller pressing 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 automobile parts, helps to improve the product competitiveness of enterprises, and reduces the production cost.
