Description

Technical Field

[0001] This utility model relates to the field of automated equipment for automotive parts forging, and more specifically, to an automated forging production line for automotive moving and stationary discs. Background Technology

[0002] Aluminum alloy forging has wide applications in industrial fields, especially in transportation, aerospace, and machinery manufacturing, where its lightweight and high strength make it a key material. However, in the manufacturing of automotive rotor and rotor discs, the traditional manual single-mold production method is still prevalent. This method relies heavily on manual labor, resulting in low production efficiency, harsh working environments, high labor intensity, and inadequate personnel safety.

[0003] Specifically, in traditional production, manual feeding and placement of materials not only wastes labor but also severely impacts production efficiency. The heating process uses a ring furnace to heat the billets in batches, resulting in discontinuous heating, low efficiency, and high costs. Manually holding the heated billets, dipping them in pre-coating liquid, and placing them directly into the press for forging easily leads to large temperature fluctuations and high personnel safety risks. Furthermore, the application of release agent is done manually with a handheld spray gun, resulting in inconsistent spraying areas, uneven application, and difficulty in controlling the spray volume. The mixing of the pre-coating liquid also relies on manual operation, leading to frequent and inefficient mixing. Finally, the deburring process involves manual feeding and lathe operation, resulting in low processing efficiency and requiring a large workforce. With the continuous development of the industrial sector, this traditional production method is gradually becoming inadequate for the demands of the modern environment, making automation, lightweighting, and digital production inevitable trends. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an automated and continuous automotive moving and stationary disc automated forging production line to solve the problems of low efficiency, high labor intensity and poor safety of traditional manual production methods.

[0005] To address the aforementioned problems, this utility model provides an automated forging production line for automotive moving and stationary discs, comprising a feeding mechanism, a preheating furnace, a graphite impregnation mechanism, a heating furnace, a press, a cooling tank, and a milling machine. The feeding mechanism is located in front of the preheating furnace and is used to supply billets to the preheating furnace. The preheating furnace is located behind the feeding mechanism and is used to preheat the billets. A first robot for transferring the preheated billets is provided between the preheating furnace and the graphite impregnation mechanism. The graphite impregnation mechanism is located behind the preheating furnace and is used to form a graphite coating on the surface of the preheated billets by impregnation. A second robot for transferring the impregnated billets is provided between the graphite impregnation mechanism and the heating furnace. The heating furnace is located within the graphite impregnation machine. The structure is located at the rear of the furnace, where the impregnated billet is heated before forging. A third robot is installed between the furnace and the press to transfer the heated billet. The press is located at the rear of the furnace and is equipped with a forging die and a spraying system. The forging die is used to forge the heated billet, and the spraying system is used to spray a release agent into the cavity of the forging die. A fourth robot is installed between the press and the cooling tank to transfer the forging. The cooling tank is located at the rear of the press and is used to cool the forging. A fifth robot is installed between the cooling tank and the milling machine to transfer the cooled forging. The milling machine is located at the rear of the cooling tank and is used to shape the cooled forging to obtain the finished automotive moving and stationary discs by milling.

[0006] Compared with existing technologies, this invention has the following advantages: Through the coordinated operation of a feeding mechanism, a preheating furnace, a heating furnace, and multiple robots, it achieves automatic feeding, continuous heating, and precise transfer of billets, effectively solving the problems of low efficiency, temperature fluctuations, and safety risks caused by traditional manual operation. The combined use of the graphite impregnation mechanism and the automatic spraying system ensures the uniformity and controllability of the billet coating and mold release agent spraying, avoiding the instability of manual dipping and spraying. The integration of the cooling pool and the milling machine enables rapid cooling and automated shaping of forgings, significantly improving the processing efficiency and consistency of the deburring process. The automated layout of the entire production line not only significantly reduces the intensity of manual labor but also achieves continuity and stability in the production process through the continuous operation of each link, providing a reliable guarantee for stable product quality.

[0007] Specifically, the feeding mechanism includes a feeding frame, a vision inspection mechanism, and a feeding robot. The feeding frame is located at the front of the preheating furnace and is used to store billets. The vision inspection mechanism is mounted above the feeding frame via a feeding rack and is used to detect the position of the billets in the feeding frame. The feeding robot is located between the feeding frame and the preheating furnace. The actuator of the feeding robot can move in the area between the feeding frame and the vision inspection mechanism to grab the billets from the feeding frame and transfer them to the preheating furnace according to the coordinates provided by the vision inspection mechanism. This technical solution achieves precise billet feeding by accurately locating the billet position through the vision inspection mechanism and combining it with the automatic grabbing and transfer by the feeding robot. This effectively improves feeding efficiency and accuracy, reduces manual intervention and error rate, and also reduces labor intensity.

[0008] Specifically, the graphite impregnation mechanism includes a first raw material mixing and supply station, a pre-coating solution proportioning station, and an impregnation tank. The first raw material mixing and supply station is connected to the pre-coating solution proportioning station via a first pipeline and is used to supply the first graphite raw material to the pre-coating solution proportioning station. The pre-coating solution proportioning station is connected to the impregnation tank via a second pipeline and is used to mix the first graphite raw material with water according to a preset first proportion to form a first graphite solution, and then supply the first graphite solution to the impregnation tank. The impregnation tank is located within the shared working area of ​​the first robot and the second robot and is used to store the first graphite solution for impregnation of the billet. This technical solution, through the pipeline connection between the first raw material mixing and supply station and the pre-coating solution proportioning station, realizes the automatic proportioning and supply of the first graphite solution, ensuring the stability of the solution concentration and quality. The impregnation tank is located within the robot's working area, automating the billet impregnation process, avoiding the unevenness and inefficiency of manual operation, thereby improving the uniformity and adhesion of the graphite coating, reducing material waste and labor costs, and improving production continuity and safety.

[0009] As an improvement, a cooling tank and an impregnation tank are nested from the outside to the inside within the impregnation tank. The cooling tank contains coolant, and the impregnation tank contains a first graphite solution. A drying rack is provided on top of the impregnation tank to hold the blanks after they have been impregnated with the graphite solution. The working principle of this technical solution is as follows: after the blanks are immersed in the impregnation tank, they are removed and placed on the drying rack. The drying rack allows excess graphite solution to drip off naturally, while the cooling tank maintains a stable temperature in the impregnation tank through coolant, preventing the solution from overheating or evaporating, thereby optimizing the coating formation process.

[0010] Specifically, the spraying system includes a solvent mixing and supply station, a second raw material mixing and supply station, a spraying liquid proportioning station, an atomization control station, and a spraying robot. The solvent mixing and supply station is connected to the spraying liquid proportioning station via a third pipeline to supply solvent to the spraying liquid proportioning station. The second raw material mixing and supply station is connected to the spraying liquid proportioning station via a fourth pipeline to supply second graphite raw material to the spraying liquid proportioning station. The spraying liquid proportioning station is connected to the atomization control station via a fifth pipeline to mix the solvent and the second graphite raw material according to a preset second proportion to prepare a second graphite solution, and supplies the second graphite solution to the atomization control station. The atomization control station is connected to the spraying robot via a sixth pipeline to deliver the second graphite solution to the spraying robot and supply compressed gas required for atomization. The spraying robot is located on one side of the press, and its nozzle can extend into the cavity of the forging mold to atomize the second graphite solution and spray it onto the inner wall of the cavity of the forging mold. This technical solution achieves precise automatic proportioning of the second graphite solution through the pipeline connection of the solvent stirring supply station, the second raw material stirring supply station, and the spraying liquid proportioning station, ensuring the stability and consistency of the mold release agent composition. After the atomization control station delivers the solution to the spraying robot, it is atomized by the spraying components on the spraying robot and uniformly sprayed under the control of the spraying robot. This avoids the problems of inconsistent spraying range and difficulty in controlling the spray volume in manual spraying, thereby improving the demolding effect and the surface quality of the forging, reducing mold wear and product defects, and reducing the intensity of manual labor and safety hazards.

[0011] As an improvement, a finished product unloading mechanism is also included on one side of the milling machine. This mechanism comprises a finished product unloading robot and a conveyor belt. The robot transfers finished automotive moving and stationary discs from the milling machine to the conveyor belt, which then transports them to a designated area. This technical solution, through the automated transfer by the robot and the continuous conveyor belt, achieves rapid unloading and centralized transfer of finished products, significantly improving production efficiency and assembly line continuity, while reducing manual handling costs and the risk of finished product damage.

[0012] As an improvement, the finished product unloading mechanism also includes a finished product unloading frame, which is located within the working range of the finished product unloading robot and is used to receive and store finished automotive moving and stationary discs from the milling machine. This technical solution provides an alternative way to unload finished products by setting up the finished product unloading frame. This method provides a centralized storage point for finished products, facilitating temporary storage and orderly management, reducing clutter on the production floor, and supporting the smooth connection of subsequent processes.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] like Figure 1As shown, an automated forging production line for automotive moving and stationary discs includes a feeding mechanism 1, a preheating furnace 2, a graphite impregnation mechanism 3, a heating furnace 4, a press 5, a cooling tank 6, and a milling machine 7. The feeding mechanism 1 is located in front of the preheating furnace 2 and is used to supply billets to the preheating furnace 2. The preheating furnace 2 is located behind the feeding mechanism 1 and is used to preheat the billets. A first robot 101 for transferring the preheated billets is provided between the preheating furnace 2 and the graphite impregnation mechanism 3. The graphite impregnation mechanism 3 is located behind the preheating furnace 2 and is used to form a graphite coating on the surface of the preheated billets by impregnation. A second robot 102 for transferring the impregnated billets is provided between the graphite impregnation mechanism 3 and the heating furnace 4. The heating furnace 4 is located behind the graphite impregnation mechanism 3. A third robot 103 for transferring the heated billet is provided between the heating furnace 4 and the press 5 for pre-forging heating of the impregnated billet; the press 5 is located behind the heating furnace 4 and is equipped with a forging die and a spraying system 8. The forging die is used to forge the heated billet into shape, and the spraying system 8 is used to spray a release agent into the cavity of the forging die. A fourth robot 104 for transferring the forging is provided between the press 5 and the cooling pool 6; the cooling pool 6 is located behind the press 5 and is used to cool the forging; a fifth robot 105 for transferring the cooled forging is provided between the cooling pool 6 and the milling machine 7; the milling machine 7 is located behind the cooling pool 6 and is used to shape the cooled forging to obtain the finished automotive moving and stationary discs by milling.

[0017] In this example, the preheating furnace 2 uses an existing medium-frequency furnace. With the help of the medium-frequency furnace's fast heating speed, the billet can be preheated in a short time to meet the needs of the entire production line for fast production.

[0018] This embodiment achieves automatic feeding, continuous heating, and precise transfer of billets through the coordinated operation of the feeding mechanism 1, preheating furnace 2, heating furnace 4, and multiple robots. This effectively solves the problems of low efficiency, temperature fluctuations, and safety risks caused by traditional manual operation. The combined use of the graphite impregnation mechanism 3 and the automatic spraying system 8 ensures the uniformity and controllability of the billet coating and mold release agent spraying, avoiding the instability of manual dipping and spraying. The integration of the cooling pool 6 and the milling machine 7 enables rapid cooling and automated shaping of forgings, significantly improving the processing efficiency and consistency of the deburring process. The automated layout of the entire production line not only significantly reduces the intensity of manual labor but also achieves continuity and stability of the production process through the coherent operation of each link, providing a reliable guarantee for the stability of product quality.

[0019] like Figure 1 , Figure 2 and Figure 4As shown, the feeding mechanism 1 includes a feeding frame 11, a vision inspection mechanism 12, and a feeding robot 13. The feeding frame 11 is located at the front of the preheating furnace 2 and is used to store billets. The vision inspection mechanism 12 is located above the feeding frame 11 via a feeding rack 14 and is used to detect the position of the billets in the feeding frame 11. The feeding robot 13 is located between the feeding frame 11 and the preheating furnace 2. The actuator of the feeding robot 13 can move in the area between the feeding frame 11 and the vision inspection mechanism 12, and is used to grab the billets from the feeding frame 11 and transfer them to the preheating furnace 2 according to the coordinates provided by the vision inspection mechanism 12. This technical solution achieves precise feeding of billets by accurately locating the position of the billets through the vision inspection mechanism 12 and combining it with the automatic grabbing and transfer of the feeding robot 13. This effectively improves the feeding efficiency and accuracy, reduces manual intervention and error rate, and reduces labor intensity. To meet the need for fast and efficient material feeding, two feeding frames 11 are usually arranged side by side (or more can be arranged in a row). When multiple feeding frames 11 are set, in order to accurately locate the blank in each feeding frame 11, the vision inspection mechanism 12 is usually moved along the arrangement direction of the feeding frames 11 on the feeding rack 14 through a linear module or other translation mechanism.

[0020] like Figure 1 and Figure 3 As shown, the graphite impregnation mechanism 3 includes a first raw material mixing and supply station 31, a pre-coating solution proportioning station 32, and an impregnation tank 33. The first raw material mixing and supply station 31 is connected to the pre-coating solution proportioning station 32 through a first pipeline and is used to supply the first graphite raw material to the pre-coating solution proportioning station 32. The pre-coating solution proportioning station 32 is connected to the impregnation tank 33 through a second pipeline and is used to mix the first graphite raw material with water according to a preset first proportion to form a first graphite solution, and supply the first graphite solution to the impregnation tank 33. The impregnation tank 33 is located in the common working area of ​​the first robot 101 and the second robot 102 and is used to store the first graphite solution for impregnation of the billet. To prevent the first graphite stock solution from settling in the first stock solution mixing and supply station 31, and to achieve uniform mixing of the first graphite stock solution and water in the pre-coating solution proportioning station 32, both the first stock solution mixing and supply station 31 and the pre-coating solution proportioning station 32 are equipped with a stirring device (existing structure) consisting of a motor and a paddle. This technical solution achieves automatic proportioning and supply of the first graphite solution through pipeline connection between the first stock solution mixing and supply station 31 and the pre-coating solution proportioning station 32, ensuring the stability of solution concentration and quality. The impregnation tank 33 is located within the robot's operating range, automating the billet impregnation process, avoiding the unevenness and inefficiency of manual operation, thereby improving the uniformity and adhesion of the graphite coating, reducing material waste and labor costs, and improving production continuity and safety.

[0021] like Figure 3As shown, a cooling tank 331 and an impregnation tank 332 are nested from the outside to the inside within the impregnation tank 33. The cooling tank 331 contains coolant, and the impregnation tank 332 contains a first graphite solution. A drying rack 333 is provided on the top of the impregnation tank 332 for placing the blank after impregnation with the graphite solution. The working principle of this technical solution is as follows: after the blank is immersed in the impregnation tank 332, it is removed and placed on the drying rack 333. The drying rack 333 allows excess graphite solution to drip off naturally. At the same time, the cooling tank 331 maintains the temperature stability of the impregnation tank 332 through the coolant, preventing the solution from overheating or evaporating, thereby optimizing the coating formation process.

[0022] like Figure 1 , Figure 6 and Figure 7 As shown, the spraying system 8 includes a solvent mixing and supply station 81, a second stock solution mixing and supply station 82, a spraying liquid mixing station 83, an atomization control station 84, and a spraying robot 85. The solvent mixing and supply station 81 is connected to the spraying liquid mixing station 83 via a third pipeline and is used to supply solvent to the spraying liquid mixing station 83. The second stock solution mixing and supply station 82 is connected to the spraying liquid mixing station 83 via a fourth pipeline and is used to supply a second graphite stock solution to the spraying liquid mixing station 83. The spraying liquid mixing station 83 is connected to the atomization control station 84 via a fifth pipeline. The connection is used to prepare a second graphite solution by mixing the solvent and the second graphite stock solution according to a preset second ratio, and to supply the second graphite solution to the atomization control station 84; the atomization control station 84 is connected to the spraying robot 85 through a sixth pipeline, and is used to deliver the second graphite solution to the spraying robot 85 and supply the compressed gas required for atomization operation; the spraying robot 85 is set on one side of the press 5, and its nozzle can extend into the cavity of the forging mold, and is used to atomize the second graphite solution and spray it onto the inner wall of the cavity of the forging mold. To prevent the second graphite stock solution from settling in the second stock solution mixing and supply station 82, and to achieve uniform mixing of the second graphite stock solution and solvent in the spraying liquid proportioning station 83, both the second stock solution mixing and supply station 82 and the spraying liquid proportioning station 83 are equipped with a stirring device (existing structure) consisting of a motor and a paddle. This technical solution achieves precise automatic proportioning of the second graphite solution through pipeline connection between the solvent mixing and supply station 81, the second stock solution mixing and supply station 82, and the spraying liquid proportioning station 83, ensuring the stability and consistency of the mold release agent composition. After the atomization control station 84 delivers the solution to the spraying robot 85, the spraying component on the spraying robot 85 atomizes the solution, and the spraying robot 85 controls the uniform spraying, avoiding the problems of inconsistent spray range and difficulty in controlling the spray volume in manual spraying. This improves the demolding effect and the surface quality of the forging, reduces mold wear and product defects, and reduces the intensity of manual labor and safety hazards.

[0023] like Figure 1 , Figure 5 and Figure 7As shown, the system also includes a finished product unloading mechanism 9 located on one side of the milling machine 7. The finished product unloading mechanism 9 includes a finished product unloading robot 91 and a conveyor belt 92. The finished product unloading robot 91 transfers finished automotive moving and stationary discs from the milling machine 7 to the conveyor belt 92, and the conveyor belt 92 transports the finished automotive moving and stationary discs to a designated area. This technical solution, through the automatic transfer of the finished product unloading robot 91 and the continuous conveying of the conveyor belt 92, achieves rapid unloading and centralized transfer of finished products, significantly improving production efficiency and assembly line continuity, while reducing manual handling costs and the risk of finished product damage.

This technical solution provides another way for finished products to be unloaded by setting up the finished product unloading frame 93. This unloading method provides a centralized storage point for finished products, which facilitates temporary storage and orderly management of finished products, reduces clutter on the production site, and supports the smooth connection of subsequent processes. In order to meet the needs of fast and efficient unloading of finished products, two finished product unloading frames 93 are usually arranged side by side (more can also be arranged in a row). At the same time, in order to achieve orderly stacking of finished automotive moving and stationary discs in the vertical direction within the finished product unloading frame 93, a grating ruler commonly used in the prior art can be installed on a set of frame edges of the finished product unloading frame 93.
