Description

Technical Field

[0001] This application relates to the technical field of forging equipment, and in particular to a forging device for automotive flanges. Background Technology

[0002] The half-shaft is a key component in a car's transmission system. Its main function is to transmit the power output from the differential or drive axle to the wheels, thereby driving the vehicle. Therefore, the half-shaft is often referred to as the drive shaft. The primary functions of the half-shaft are power transmission and motion adaptation. The torque generated by the engine and transmission is distributed to the wheels via the differential. Simultaneously, because the wheels bounce up and down during driving and sway left and right during steering, the half-shaft can adapt to these changes in angle and length while maintaining smooth power transmission.

[0003] A flange is typically fixed to one end of the half-shaft. The main function of this flange is to ensure a reliable and stable connection and power transmission between the half-shaft and the wheel hub. The flange is generally formed through a forging process. First, the metal blank at one end of the half-shaft is heated and melted. Then, the molten metal blank is uprooted to facilitate the subsequent forging steps. Finally, the uprooted metal blank is forged under the pressure of a forging press to form the final flange shape. After forging, the flange needs to be naturally cooled, i.e., air-cooled. Because the forged flange is still at a relatively high temperature, air cooling optimizes the internal structure of the flange, eliminates harmful internal stresses, improves the flange's toughness and plasticity, and prevents cracks and deformation.

[0004] In the actual forging process, the flange of the half shaft is usually loaded and unloaded manually. Since the combination of half shaft and flange has a certain weight, there is a risk of burns if the manual handling is not firm. In addition, there is usually no step to inspect the forging quality of the flange after forging, which makes it difficult to guarantee the forging quality of the flange. Summary of the Invention

[0005] To address the risks of burns associated with manual loading and unloading during flange forging and the resulting compromise in flange forging quality, this application provides an automotive flange forging processing device.

[0006] This application provides a forging and pressing device for automotive flanges, which adopts the following technical solution: An automotive flange forging processing apparatus, comprising: The feeding mechanism is used to feed the half-shafts to be heated to the heating mechanism; Heating mechanism, used to heat and melt one end of the half shaft; The forging mechanism is used to forge one end of the half shaft that has been heated and melted to form a flange at one end of the half shaft. The heating mechanism is located between the feeding mechanism and the forging mechanism. The unloading mechanism is used to transfer and unload the forged half shaft. The unloading mechanism includes a detection component, which is used to inspect the shape quality of the flange during the unloading process.

[0007] Optionally, the forging mechanism includes a vertically placed positioning frame, which includes two separate and symmetrically spaced support bodies, which are used to jointly support the half shaft. The feeding mechanism includes a flip-up feeding frame, which is a V-shaped frame with an upward opening. The feeding frame includes a rotating rod located at the intersection of the V-shaped frame and two connecting frames extending to both sides. The rotation axis of the feeding frame is horizontal and coaxial with the rotating rod. The ends of the two connecting frames are provided with a receiving rod parallel to the rotating rod. When the feeding frame flips, the receiving rod of one of the connecting frames can swing in the gap between the two supports, so that the receiving rod can lift the half shaft from below and feed the half shaft as the feeding frame flips.

[0008] Optionally, the detection component includes a follower plate that slides along the length of the connecting frame. The follower plate is used to contact the outer peripheral surface of the flange and move as the flange descends. A laser emitter and a laser receiver are provided on the follower plate. The laser emitter and laser receiver are respectively spaced apart on both sides of the flange axis and are located at the positions where the outer peripheral surface of the flange contacts the follower plate. An anti-slip pad is provided on the outer wall of the connecting frame that contacts the half shaft.

[0009] Optionally, the forging mechanism includes a frame, with a die head horizontally slidably connected inside the frame. The die head is used to forge one end of the half-shaft that has been heated and melted. A forging drive component is provided on the frame to drive the die head to slide. Both of the two support bodies are provided with lower forming dies at the top. An upper forming die that can be vertically raised and lowered is provided on the frame directly above the support bodies. After the upper forming die and the two lower forming dies are closed, a mold cavity for forming the flange is formed.

[0010] Optionally, the frame is provided with a mounting base, and the forging drive is used to drive the mounting base to slide horizontally. A template is horizontally slidably connected to the side wall of the mounting base near the support body. The die head is set on the side wall of the template. The die head includes a first die head, a second die head and a third die head. The first die head and the second die head are respectively used to perform a first upsetting and a second upsetting on the heated and melted end of the half shaft. The third die head is used to forge the half shaft after upsetting.

[0011] Optionally, the feeding mechanism includes a fixed frame, which is disposed on one side of the frame. A first feeding plate inclined downward is disposed on the fixed frame. A feeding component and a switching component are respectively disposed on the upper and lower sides of the first feeding plate. The feeding component is used to feed half shafts onto the first feeding plate one by one, and the switching component is used to feed half shafts onto the heating mechanism one by one.

[0012] Optionally, the heating mechanism includes a heating coil and a second feeding plate. The second feeding plate is inclined downward on the fixed frame. The top end of the second feeding plate is supported by the bottom end of the first feeding plate and is offset from the first feeding plate. The heating coil is correspondingly disposed at the bottom position of the second feeding plate on the side away from the first feeding plate, and is used to heat and melt one end of the half shaft.

[0013] Optionally, a transfer mechanism is provided between the second feeding plate and the frame. The transfer mechanism includes a mechanical clamping arm that can swing back and forth between the second feeding plate and the frame to transfer the half shaft from the second feeding plate to the top of the two supports.

[0014] In summary, this application includes at least one of the following beneficial effects: 1. By setting a rotating unloading rack, which includes support rods at both ends of a V-shaped frame, during unloading, one of the support rods is located in the gap between the two supports and below the half-shaft. After the flange at one end of the half-shaft is forged, the unloading rack drives the support rod below the half-shaft to rotate. The support rod first lifts the half-shaft and moves it away from the support. As the unloading rack continues to rotate, the half-shaft slides down the inclined connecting frame into the V-shaped frame of the unloading rack. During the descent of the half-shaft, the outer circumference of the forged flange touches the follower plate, causing the follower plate to move with the half-shaft. When the half-shaft falls along the connecting frame, it contacts the anti-slip pad on the surface of the connecting frame, causing the half-shaft to rotate as it falls. Since the laser emitter and laser receiver are located on both sides of the flange and corresponding to the contact positions between the flange and the follower plate, the laser beam emitted by the laser emitter can be directed towards the flange. As the half-shaft descends, the flange rotates continuously, and the laser emitter scans all edges of the flange. If the laser receiver fails to receive a light signal during this process, it indicates that the forged flange is intact and there is no underfilling, meaning the flange's shape quality is acceptable. Conversely, if the laser receiver receives light signals intermittently, it indicates that there are gaps or incomplete filling at the flange's edges, indicating a forming defect. The entire inspection process is completed synchronously during the half-shaft unloading process, achieving both automatic unloading and real-time inspection of the flange's shape quality. This significantly improves production efficiency and ensures product quality stability. Furthermore, the forging process of the half-shaft is automated throughout the entire flange forging process, including unloading, loading, and forging steps, effectively reducing manual operation time and greatly lowering the risk of injury to personnel. 2. The template integrates three different functional mold heads, and the template can move horizontally. The first and second mold heads are used to perform primary and secondary upsetting on the heated and melted end of the half shaft, respectively. The third mold head can forge the half shaft after upsetting to form the final flange. Therefore, the half shaft to be forged can undergo all the upsetting and forging processes in the same forging step, realizing one-time forming of the flange. This can reduce the processing errors and time losses caused by frequent transfer of the half shaft, and improve the overall processing accuracy and efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0018] The flange at one end of the half shaft is generally formed by forging. First, the metal billet at one end of the half shaft is heated and melted. Then, the molten metal billet is uprooted and shaped. Finally, it is forged under the pressure of the forging press to form the final flange shape.

[0019] In the actual forging process, the flange of the half-shaft is usually loaded and unloaded manually. Since the combination of the half-shaft and the flange has a certain weight, and one end of the half-shaft needs to be heated to a molten state, there is a risk of burns if the manual handling is not handled securely. Furthermore, there is usually no timely inspection of the forging quality of the flange after forging, especially the inspection of the flange's shape quality. During actual forging, the half-shaft may not be heated thoroughly, resulting in insufficient fluidity of the heated metal block and incomplete filling of the mold. That is, the molten metal block cannot completely fill the mold cavity due to insufficient fluidity, and the forged flange has defects on the outer periphery. This makes it difficult to guarantee the final forging quality of the flange.

[0020] Based on the above problems, this application discloses an automotive flange forging processing apparatus, see reference. Figure 1 and Figure 2 The automotive flange forging processing device includes a feeding mechanism 1, a heating mechanism 2, a forging mechanism 3, and a discharging mechanism 4. The discharging mechanism 4 includes a detection component, which can perform shape quality inspection on the flange 51 during the discharging process.

[0021] Understandably, the feeding mechanism 1 automatically feeds the half-shaft 5 to the heating mechanism 2, which heats and melts one end of the half-shaft 5. Then, the forging mechanism 3 forges and shapes the melted end of the half-shaft 5, ultimately forming a flange 51 at one end. Finally, the unloading mechanism 4 automatically transfers and unloads the forged half-shaft 5. The entire forging process is completed automatically by these mechanisms, significantly reducing manual intervention and effectively lowering the risk of injury to personnel handling the half-shaft 5. Simultaneously, the inspection component can detect the shape quality of the flange 51 in real time during the unloading process, reducing the probability of defective products due to insufficient filling flowing into subsequent processes. Furthermore, the inspection process can be integrated into the unloading flow, improving inspection efficiency and production line automation, and avoiding additional quality inspection stations that could cause cycle time delays.

[0022] For example, the feeding mechanism 1 includes a fixed frame 11, the forging mechanism 3 includes a frame 31, the fixed frames 11 are spaced apart on one side of the frame 31, and the heating mechanism 2 is located between the feeding mechanism 1 and the forging mechanism 3. Multiple horizontal and parallel crossbeams 111 are welded to the top of the fixed frame 11. The crossbeams 111 are parallel to the length of the frame 31, and the height of each crossbeam 111 gradually decreases along the direction closest to the frame 31. A feeding groove 112 is provided on the top surface of the crossbeam 111 furthest from the frame 31. The feeding groove 112 extends along the length of the crossbeam 111 and is used to carry and guide the half-shafts 5 to be heated to the next station. The feeding groove 112 can accommodate multiple half-shafts 5 simultaneously. A feeding drive unit 113 is fixed at one end of a crossbeam 111 with a feeding trough 112. The feeding drive unit 113 is preferably a telescopic cylinder. The piston rod of the feeding drive unit 113 is arranged along the length of the crossbeam 111. When the piston rod of the feeding drive unit 113 is extended, it can push the half shaft 5 to slide along the feeding trough 112. A feeding platform can be set on the side of the fixed frame 11 away from the frame 31 to facilitate the operator to place half shafts 5 in batches in the feeding trough 112, or a feeding conveyor belt can be directly connected to the feeding trough 112 to realize continuous automatic feeding of half shafts 5.

[0023] Furthermore, a first feeding plate 12 inclined downwards is fixed to the crossbeam 111 on the fixing frame 11. The first feeding plate 12 is located on one side of the output end of the feeding trough 112, and its inclination angle is adapted to the height change trend of the crossbeam 111. A baffle is fixed to the crossbeam 111 at the position corresponding to the first feeding plate 12, and the baffle can prevent the half shaft 5 from dislodging from the feeding trough 112. A feeding cylinder 114 is fixed to the side of the fixing frame 11 corresponding to the position of the first feeding plate 12. The piston rod of the feeding cylinder 114 can push the half shaft 5 to fall onto the first feeding plate 12, so that the half shaft 5 slides down the inclined surface of the first feeding plate 12. The length of the first feeding plate 12 can accommodate multiple half shafts 5 at the same time. A baffle is fixed to one bottom end of the first feeding plate 12, which can limit the stroke of the half shaft 5 and prevent the half shaft 5 from excessive displacement and falling. The heating mechanism 2 is located at the bottom of the first feeding plate 12. To facilitate the smooth entry of the half-shaft 5 from the first feeding plate 12 into the heating area of ​​the heating mechanism 2, a switching cylinder 115 is fixed on the crossbeam 111 at the bottom of the first feeding plate 12. The piston rod of the switching cylinder 115 can push the bottom half-shaft 5 to disengage from the first feeding plate 12 and slide down to the feeding end of the heating mechanism 2. After the bottom half-shaft 5 disengages from the first feeding plate 12, the remaining half-shafts 5 on the first feeding plate 12 fall down by their own weight to prepare for the next feeding.

[0024] For example, refer to Figures 2 to 4The heating mechanism 2 includes a heating coil 21 and a second feeding plate 22. The second feeding plate 22 is also fixed downwards and inclined on the crossbeam 111. The top of the second feeding plate 22 corresponds to the bottom of the first feeding plate 12, and the second feeding plate 22 and the first feeding plate 12 are offset from each other. The switching cylinder 115 can push the half-shaft 5 on the first feeding plate 12 to fall onto the second feeding plate 22. The second feeding plate 22 can also accommodate multiple half-shafts 5 at the same time. The heating coil 21 is wrapped around the bottom of the second feeding plate 22 and on the outer periphery of the side away from the first feeding plate 12. The heating coil 21 is connected to an external power cable. It heats the passing half-shafts 5 using the principle of electromagnetic induction. By passing high-frequency alternating current into the heating coil 21, the heating coil 21 generates an alternating magnetic field, which in turn generates a high-density induced eddy current at the end position of the half-shaft 5. The end of the half-shaft 5 is then rapidly and uniformly heated through the resistance heating effect of the material itself. The heating temperature can be precisely controlled by adjusting the current frequency and intensity. The specific methods by which induction coils heat metal materials are well known to those skilled in the art and have been widely and maturely applied in this field, and will not be elaborated upon here.

[0025] In some embodiments, the heating coil 21 is wound in a C-shape with the opening tilted upwards. A baffle is also fixed to one bottom end of the second feeding plate 22 to prevent the half shaft 5 from falling off the second feeding plate 22. When the half shaft 5 at the bottom of the second feeding plate 22 is blocked by the baffle, one end of the half shaft 5 falls into the C-shaped opening of the heating coil 21. At this time, a high-frequency alternating current can be supplied to the heating coil 21 by an external alternating power supply to heat the end of the half shaft 5. As the heating coil 21 continues to heat, the temperature of the end of the half shaft 5 rises rapidly to the range required by the process.

[0026] For example, a mechanical clamping arm 6 is provided between the second feeding plate 22 and the frame 31. The clamping hand of the mechanical clamping arm 6 can swing back and forth between the second feeding plate 22 and the frame 31. The mechanical clamping arm 6 is rotatably connected to the fixed frame 11. The reciprocating swing of the mechanical clamping arm 6 can be realized by a rotary motor also mounted on the fixed frame 11. A feeding cylinder 116 is fixed on the side of the fixed frame 11 corresponding to the second feeding plate 22 away from the first feeding plate 12. The output shaft of the feeding cylinder 116 can extend horizontally into the C-shaped opening of the heating coil 21, thereby pushing the lowermost half shaft 5 on the second feeding plate 22 away from the second feeding plate 22. The mechanical clamping arm 6 is located on the side of the second feeding plate 22 away from the feeding cylinder 116. The half shaft 5, which is pushed away from the second feeding plate 22 by the feeding cylinder 116, falls into the clamping hand at the end of the mechanical clamping arm 6 and is clamped and fixed by the clamping hand. Then the mechanical clamping arm 6 swings, which can transfer the half shaft 5 from the second feeding plate 22 to the frame 31 for the next forging operation.

[0027] For example, refer to Figures 4 to 7 The frame 31 contains four horizontally placed guide posts 311 arranged in a rectangular shape and parallel to each other. Mounting seats 32 are horizontally slidably connected to the guide posts 311, with the four guide posts 311 passing through the four corners of the mounting seats 32. The mounting seats 32 can slide back and forth horizontally on the guide posts 311. A forging drive component 312 is fixed to the outer side of the frame 31 corresponding to the mounting seats 32. The forging drive component 312 is preferably a high-thrust forging cylinder. The output shaft of the forging drive component 312 is fixedly connected to the mounting seats 32, driving the mounting seats 32 to reciprocate along the length of the guide posts 311.

[0028] In some embodiments, a template 33 is horizontally slidably connected to the side wall of the mounting base 32 away from the forging drive member 312. The movement direction of the template 33 is horizontal and perpendicular to the movement direction of the mounting base 32. A head-changing cylinder 321 is fixed to one end of the mounting base 32 corresponding to the movement direction of the template 33. The output shaft of the head-changing cylinder 321 is fixedly connected to the end of the template 33, which can drive the template 33 to reciprocate along the horizontal and perpendicular movement direction of the mounting base 32, thereby performing the operation of switching different dies. Multiple dies are fixed to the side wall of the template 33 away from the forging drive member 312. Each die corresponds to the forming requirements of different forging processes. In the embodiment of this application, three dies are provided, namely a first die 331, a second die 332, and a third die 333. The three dies are arranged side by side and spaced apart on the side wall of the template 33. The first die 331 and the second die 332 are used to perform a first and second upsetting on the heated and melted end of the half shaft 5, respectively. The third die 333 is used to forge the end of the half shaft 5 after upsetting.

[0029] In the actual forging process, the head-changing cylinder 321 drives the template 33 to move laterally according to the preset program, and sequentially and accurately positions the first die head 331, the second die head 332 and the third die head 333 to the processing position at the end of the half shaft 5, ensuring that the forming process of each stage is connected in an orderly manner. Therefore, the half shaft 5 to be forged can be subjected to two head-up and forging steps in the same forging process, realizing the one-time forming of the flange 51. This can reduce the processing error and time loss caused by frequent transfer of the half shaft 5, and improve the overall processing accuracy and efficiency.

[0030] In some embodiments, a vertically placed positioning frame 34 is fixed inside the frame 31. The positioning frame 34 includes two support bodies 341 with split tops and symmetrically spaced apart. The tops of the two support bodies 341 can jointly support the half shaft 5. After the mechanical clamping arm 6 swings, it can accurately move the half shaft 5 to the tops of the two support bodies 341. The tops of the two support bodies 341 are provided with inclined surfaces for positioning the half shaft 5. The inclined surfaces at the tops of the two support bodies 341 together form an upward-opening V-shaped positioning groove, which can adaptively clamp half shafts 5 of different diameters. The side walls of the two support bodies 341 are respectively horizontally slidably connected to a lower forming mold 342. The two lower forming molds 342 are symmetrically distributed and can form a cavity for forming the flange 51 after closing. The two lower forming molds 342 are driven to reciprocate by a telescopic electric cylinder to achieve closing or opening. A limiting cylinder 313 is fixed directly above the support body 341 on the frame 31. The output shaft of the limiting cylinder 313 points vertically downward, and an upper forming mold 343 is fixed to the end of the output shaft. The limiting cylinder 313 can drive the upper forming mold 343 to rise and fall. The upper forming mold 343 corresponds to the two lower forming molds 342, and after the upper forming mold 343 and the two lower forming molds 342 are closed, a complete mold cavity for forming the flange 51 can be formed. During forging, the third die head 333 moves and aligns with the formed mold cavity, and applies continuous forming pressure to the molten part at the end of the half shaft 5 to ensure that the molten metal block fully fills the mold cavity, thereby forming the final flange 51.

[0031] For example, refer to Figures 6 to 9 The unloading mechanism 4 includes a flip-up unloading frame 41, which is a V-shaped frame with an upward opening. The unloading frame 41 includes a rotating rod 411 located at the bottom junction of the V-shaped frame and two connecting frames 412 extending to both sides. The top surface of each connecting frame 412 is covered with an anti-slip pad 414. The rotation axis of the unloading frame 41 is horizontal and coaxial with the rotating rod 411. A unloading motor that drives the unloading frame 41 to rotate is fixed on the frame 31. The ends of the two connecting frames 412 are each fixed with a receiving rod 413 parallel to the rotating rod 411. During forging, one of the receiving rods 413 is located in the gap between the two supports 341 and below the half-shaft 5 to be processed. A limiting block is fixed on the outer wall of the receiving rod 413. The limiting block protrudes from the outer wall surface of the receiving rod 413 and is distributed on both sides of the axis of the half shaft 5. When the receiving rod 413 swings with the unloading frame 41, the limiting block on the receiving rod 413 can contact the outer wall of the half shaft 5 and restrict the movement of the half shaft 5. A pushing cylinder is also fixed on the side wall of the positioning frame 34. The output shaft of the pushing cylinder is parallel to the half shaft 5. After the flange 51 at the end of the half shaft 5 is forged, the pushing cylinder can actively push the formed flange 51 away from the lower forming mold 342.

[0032] Understandably, after the flange 51 is forged, the push cylinder first pushes the half shaft 5 laterally, causing the flange 51 to detach from the forming mold cavity. Then, the unloading frame 41 swings as a whole. When the receiving rod 413 swings with the unloading frame 41, the receiving rod 413 will swing around the axis of the rotating rod 411. During this process, the receiving rod 413 will gradually rise and push the forged half shaft 5 to detach from the V-shaped positioning groove of the support body 341. At this time, the tilt angle of the receiving rod 413 corresponding to the connecting frame 412 gradually increases. The limiting block on the receiving rod 413 plays a role in restricting the movement of the half shaft 5 and preventing the half shaft 5 from falling off due to inertia or positional displacement during the lifting process. The receiving rod 413 continues to swing with the unloading frame 41. When the receiving rod 413 rises to a certain angle, the half-shaft 5 will disengage from the limiting block and slide down along the inclined connecting frame 412. The outer wall of the half-shaft 5 will rub against the anti-slip pad 414 on the surface of the connecting frame 412. The anti-slip pad 414 can effectively increase the friction between the half-shaft 5 and reduce the falling speed of the half-shaft 5, while allowing the half-shaft 5 to roll and rotate as it falls. A receiving frame can be set on the side of the unloading frame 41 away from the support 341. Under the action of inertia, the half-shaft 5 on the unloading frame 41 continues to roll down along the surface of another connecting frame 412 onto the receiving frame, completing the automatic unloading.

[0033] In some embodiments, in order to perform shape quality inspection on the flange 51 after the forging process while unloading, an inspection component is also provided on the unloading rack 41. The inspection component includes a follower plate 42, which is located on one side of the connecting frame 412. The follower plate 42 has an overall L-shaped structure, with the opening of the L-shaped structure tilted upwards to receive the forged flange 51. A rotating shaft 421 is rotatably connected to the follower plate 42 at the included angle of its L-shaped structure. A sliding groove is provided through the connecting frame 412 on the side near the flange 51 of the half-shaft 5. The rotating shaft 421 of the follower plate 42 passes horizontally through and is slidably connected in the sliding groove, so that the follower plate 42 can slide along the length of the connecting frame 412. A return element 43 is fixedly connected to the inner wall of the top of the connecting bracket 412 corresponding to the slide groove. The return element 43 is preferably a tension spring. The bottom end of the return element 43 is fixedly connected to the rotating shaft 421 of the follower plate 42, which can provide an upward restoring force for the follower plate 42. A torsion spring is provided at the end of the rotating shaft 421. One end of the torsion spring is fixed to the end of the rotating shaft 421, and the other end is fixed to the follower plate 42, so that the follower plate 42 can maintain an upward tilted state so that the follower plate 42 can maintain the posture of receiving the flange 51.

[0034] As the flange 51 rolls down along the connecting frame 412, it simultaneously contacts and applies pressure to the two L-shaped sides of the connecting frame 412, forcing the follower plate 42 to overcome the tension of the return piece 43 and slide down the slide along the groove with the flange 51. When the flange 51 slides to the end of the connecting frame 412, the follower plate 42 stops sliding and, under the gravity of the flange 51, begins to rotate along the pivot 421, causing the opening of the follower plate 42 to gradually change from tilted upward to horizontal or even slightly downward, causing the flange 51 to slide out and continue to slide down to the receiving frame along another receiving frame, thus completing the automatic unloading. The follower plate 42 is reset under the tension of the return piece 43 and returns to its initial tilted upward posture. To ensure that the rotating shaft 421 always slides stably within the slide groove, one end of the rotating shaft 421 extends out of the connecting frame 412 and is fixed with a slider. The slider slides in contact with the outer wall of the connecting frame 412, and the slider can restrict the rotating shaft 421 from coming out of the slide groove, ensuring that the follower plate 42 moves smoothly and reliably.

[0035] Furthermore, a laser emitter 422 and a laser receiver 423 are fixed on the follower plate 42. The laser emitter 422 and the laser receiver 423 are respectively disposed on both sides of the flange 51 along the axial direction and are located at the positions where the outer peripheral surface of the flange 51 contacts the follower plate 42. There are two sliding contact positions between the flange 51 and the follower plate 42. In this embodiment, the laser emitter 422 and the laser receiver 423 are located on the side wall of the follower plate 42 perpendicular to the connecting frame 412. The laser beam emitted by the laser emitter 422 passes through the outer edge of the flange 51 and is captured by the laser receiver 423.

[0036] As the half-shaft 5 falls, both the flange 51 and the half-shaft 5 rotate continuously. The position of the laser emitter 422 relative to the follower plate 42 remains unchanged, and the laser beam emitted by the laser emitter 422 can continuously scan all edge positions of the flange 51. During this process, if the laser receiver 423 fails to receive a light signal, it indicates that the forged flange 51 is intact and the outer periphery of the flange 51 is free of defects. This indicates that the flange 51 is not underfilled and its shape quality is acceptable. Conversely, if the laser receiver 423 receives a light signal intermittently, it indicates that the outer periphery of the flange 51 has gaps or incomplete filling. This indicates that the flange 51 has a forming defect. This reflects that the end of the half-shaft 5 used to forge the flange 51 has not been heated sufficiently. The intensity or frequency of the current supplied to the heating coil 21 should be increased to heat the end of the half-shaft 5 more fully. This ensures that the half-shaft 5 is heated to a temperature more suitable for forging, so that the molten material at the end of the half-shaft 5 can flow fully during forging to fill the mold cavity and prevent defects from appearing on the outer periphery of the flange 51 after forging.

[0037] The implementation principle of the automotive flange forging processing device in this application embodiment is as follows: the loading drive 113 drives the half shaft 5 to move to the first feeding plate 12, so that the half shaft 5 slides down along the inclined first feeding plate 12 and forms a material pile. Then, the half shaft 5 slides down along the second feeding plate 22 under the drive of the switching cylinder 115, so that the half shaft 5 is arranged sequentially on the second feeding plate 22 and forms a new material pile. The half shaft 5 at the bottom of the second feeding plate 22 is uniformly heated to a suitable forging temperature under the action of the heating coil 21. Then, the heated half shaft 5 is transferred to the positioning frame 34 by the mechanical clamping arm 6. The end of the half shaft 5 is forged step by step by three die heads. Finally, the unloading frame 41 flips, so that the forged half shaft 5 slides down along the connecting frame 412. During the sliding process, the laser detection system on the follower plate 42 monitors the edge forming quality of the flange 51 in real time.
