Description

Technical Field

[0001] This invention relates to the field of intelligent forging equipment technology, specifically to a forging equipment and forging method for input shaft gears used in new energy vehicles. Background Technology

[0002] Forging of automotive input shaft gears is a crucial step in their manufacturing process, directly affecting the gear's strength, lifespan, and reliability. Input shaft gears need to withstand the torque transmitted from the engine, frequent shifting shocks, and complex alternating loads, thus requiring extremely high material properties and structural integrity. Current automotive input shaft gear forging involves various equipment and, according to process steps, includes billet preparation, pre-forging, final forging, trimming, and finishing, forming an automated production line.

[0003] In the existing forging process of automotive input shaft gears, its core value lies in significantly improving the internal quality and mechanical properties of gear materials through plastic deformation and precise control, especially optimizing the distribution of metal flow lines. This endows the gears with excellent load-bearing capacity, fatigue resistance, and long service life, in order to meet the stringent requirements of modern automotive transmission systems for power, reliability, and durability. However, existing gear forging processes suffer from problems such as the forging metal not being able to completely fill the mold cavity, resulting in incomplete forged gears; slow cavity filling time; metal cooling and stratification; insufficient strength at the gear tooth root; and the need to grind and remove the flash from the blank produced by stamping and forging, which reduces production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a forging equipment and forging method for input shaft gears used in new energy vehicles, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A forging equipment and forging method for input shaft gears for new energy vehicles includes a base frame, a control box, a steering conveyor belt, a cutting machine, an electro-hydraulic hammer machine, a final forging mechanism, an electrically controlled sliding table, and a multi-axis robotic arm. The final forging mechanism includes a gantry frame and a base plate. The control box, steering conveyor belt, cutting machine, electro-hydraulic hammer machine, gantry frame, base plate, and electrically controlled sliding table are all fixedly connected to the base frame. The multi-axis robotic arm is fixedly connected to the electrically controlled sliding table. The steering conveyor belt, cutting machine, electro-hydraulic hammer machine, final forging mechanism, electrically controlled sliding table, and multi-axis robotic arm are all connected to the control box via electrical signals.

[0006] This invention relates to a forging device for input shaft gears in new energy vehicles. A steering conveyor belt transports rolled billets to a cutting machine. According to the electrical control signals from the control box, the cutting machine precisely cuts the billets to the required volume. A multi-axis robotic arm transports the rough billet to an external heating furnace for heating. The multi-axis robotic arm then transports the heated rough billet to an electro-hydraulic hammer press for preliminary hammer forging. An electrically controlled sliding table drives the multi-axis robotic arm to move and transport the initially forged rough billet to the final forging mechanism. The final forging mechanism precision forges the rough billet into a tooth shape. During precision forging, the final forging mechanism performs multiple fine-tuning forging pressures on the upper surface of the rough billet in sections, while simultaneously punching the sides of the rough billet to increase the deformation speed and pressure of the rough billet, ensuring that the metal fills the die cavity, eliminating flash generated during forging, and significantly improving the forging quality.

[0007] Furthermore, the final forging mechanism also includes a drive screw, a slide table, a drive motor, and a forging mechanism. The slide table is provided with threaded holes and through holes. There are two sets of drive screws and threaded holes. The drive screw is rotatably connected to the gantry frame, and the drive screw is connected to the threaded holes by threads. The forging mechanism includes a rotating shaft, a rotary motor, and a pressure dividing mechanism. The pressure dividing mechanism includes a first motor. The rotating shaft is rotatably connected to the through holes, and the rotary motor is fixedly connected to the slide table. The drive screw, drive motor, rotary motor, and first motor are all connected to the control box by electrical signals.

[0008] The electrically controlled sliding table drives the multi-axis robotic arm to move and transport the initial forging blank to the base plate. The drive screw outputs a fixed-axis torque. Through the threaded connection between the drive screw and the threaded hole, the sliding table moves downward along the drive screw, driving the pressure dividing mechanism to perform stamping and hammering forging on the blank located on the tooth die. The rotary motor drives the pressure dividing mechanism to rotate, and the upper surface of the blank is subjected to multiple fine-tuning forgings in sections.

[0009] Furthermore, the final forging mechanism also includes a one-way pulley, a side punching mechanism, and a toothed die. The side punching mechanism includes a ring housing, a belt ring, and a base platform. The drive motor, ring housing, base platform, and toothed die are all fixedly connected to the base plate. The output end of the drive motor is unidirectionally rotatably connected to the one-way pulley. The one-way pulley and belt ring are connected via belt drive, and the belt ring is rotatably connected to the ring housing.

[0010] Before the pressure-dividing mechanism performs stamping and hammering on the blank located on the die, the drive motor outputs a fixed-axis torque to the one-way pulley. The output torque direction is opposite to the allowable rotation direction of the one-way pulley. The torque is transmitted to the belt ring through the belt. The belt ring rotates and the side punching mechanism stores energy. At the same time, the side punching mechanism counter-punches the die to forge the blank, which increases the deformation speed and pressure of the blank and ensures that the metal fills the die cavity.

[0011] Furthermore, the side punching mechanism also includes a protruding tooth root component and a concave die component. A sliding groove and a limiting buckle are provided on the bottom platform. Several sets of protruding tooth root components, concave die components, sliding grooves, and limiting buckles are provided. Several sets of protruding tooth root components, concave die components, sliding grooves, and limiting buckles are evenly distributed along the circumference of the ring shell. The protruding tooth root components and concave die components are arranged adjacent to each other. The protruding tooth root components and concave die components are slidably connected to the sliding groove.

[0012] Several sets of protruding tooth root parts and concave die parts, evenly distributed along the circumference of the ring shell, store energy before hammer forging. The protruding tooth root parts and concave die parts slide along the slide groove in a direction away from the center of the tooth die. When the rough blank located on the tooth die is stamped and hammered, the protruding tooth root parts and concave die parts move in the opposite direction to the center. The protruding tooth root parts impact the tooth root position of the tooth die, and the concave die parts impact the tooth peak position of the tooth die, thereby increasing the deformation speed and pressure of the rough blank and ensuring that the metal fills the die cavity.

[0013] Furthermore, the side-impact mechanism also includes a limiting spring, a rack, a shaft, and a compression spring. Several sets of limiting springs, racks, shafts, and compression springs are provided, and these sets are evenly distributed along the circumference of the ring shell. The limiting springs, racks, and compression springs are all fixedly connected to the tooth root component. The limiting springs contact the limiting buckle, and the compression springs are fixedly connected to the ring shell. The shaft is provided with a half-amplitude gear and an upper gear, and the belt ring is provided with an internal gear ring. The upper gear meshes with the tooth surface of the internal gear ring, and the half-amplitude gear meshes with the tooth surface of the rack.

[0014] The drive motor transmits torque through the belt, causing the belt ring to rotate. The rotation of the belt ring, through the meshing of the internal gear ring and the upper gear, transmits the torque of the belt ring to the shaft. The shaft rotates around its axis and, through the meshing of the half-width gear and the rack, transmits the shaft torque to the rack. The protruding tooth root part and the concave die part slide along the slide groove away from the center of the tooth die, compressing the spring. The limit spring contact with the limit buckle to complete the energy storage. During stamping and hammer forging, the limit buckle breaks through the limit spring, the compressed spring recovers its deformation, and pushes the protruding tooth root part to impact the tooth root position of the tooth die, and the concave die part to impact the tooth peak position of the tooth die, increasing the deformation speed and pressure of the blank and ensuring that the metal fills the die cavity.

[0015] Furthermore, the forging mechanism also includes a first gear rod, a ball joint rod, a chassis, and a servo cylinder. The output end of the rotary motor is fixedly connected to the first gear rod. The rotating shaft is provided with a side tooth groove and a hemispherical cavity. The first gear rod meshes with the tooth surface of the side tooth groove, the ball joint rod contacts the hemispherical cavity, and the chassis is fixedly connected to the rotating shaft. The pressure dividing mechanism also includes an outer cylinder and a bottom cylinder. The outer cylinder is fixedly connected to both the ball joint rod and the bottom cylinder. The servo cylinder is hinged to the chassis, and the output end of the servo cylinder is hinged to the bottom cylinder.

[0016] The rotary motor outputs fixed-axis torque to the first gear rod. Through the meshing of the teeth between the first gear rod and the side tooth groove, the rotary motor torque is transmitted to the rotating shaft. The rotating shaft rotates around its axis in the through hole. The output end of the servo cylinder is displaced according to the electrical control signal of the control box. The output end of the servo cylinder is hinged to the bottom cylinder. The ball head rod deflects in the hemispherical cavity to adjust the tilt angle of the upper surface of the stamping blank of the pressure dividing mechanism.

[0017] Furthermore, the pressure-dividing mechanism also includes a conical disc, a connecting rod, a sliding disc, a second gear rod, and a gear frame. The connecting rod is fixedly connected to the conical disc and the sliding disc. The conical disc contacts the bottom cylinder, the sliding disc is slidably connected to the outer cylinder, the gear frame is fixedly connected to the sliding disc, the first motor is fixedly connected to the outer cylinder, the output end of the first motor is fixedly connected to the second gear rod, and the second gear rod meshes with the tooth surface of the gear frame.

[0018] When stamping the upper surface of the blank, the first motor outputs a fixed-axis torque to the second gear rod. The torque is transmitted through the meshing of the teeth between the second gear rod and the gear frame. The slide plate drives the conical disc to move closer to the ball head rod. During stamping, the outer cylinder contacts the blank first. The first motor outputs a reverse torque to make the conical disc move away from the ball head rod. The conical disc then contacts the blank. The outer edge of the blank is stamped first, causing the edge of the blank to gather inward. The conical disc then contacts the blank, flattening the blank that is gathering towards the center. This can effectively eliminate the flash phenomenon of stamping and hammer forging and improve the forging quality.

[0019] Furthermore, the forging method includes the following steps: 1) The turning conveyor belt transports the billet to the cutting machine for cutting: The turning conveyor belt transports the rolled billet to the cutting machine, and the cutting machine precisely cuts the billet to the required volume according to the electrical control signal of the control box.

[0020] 2) Multi-axis robotic arm transports the blank to the heating furnace: The multi-axis robotic arm transports the blank to the external heating furnace for heating.

[0021] 3) The multi-axis robotic arm places the heated billet into the electro-hydraulic hammer for initial forging: The multi-axis robotic arm transports the heated billet to the electro-hydraulic hammer machine to complete the initial hammer forging.

[0022] 4) The multi-axis robotic arm transports the pre-forged billet to the final forging mechanism to complete the final precision forging: The electrically controlled sliding table drives the multi-axis robotic arm to move and transport the pre-forged billet to the final forging mechanism, which then precision forges the billet into a tooth shape.

[0023] Compared with the prior art, the beneficial effects of this invention are as follows: This invention designs a side punching mechanism, which drives the belt ring to rotate via a drive motor. The rotation of the belt ring, through the meshing of the internal gear ring and the upper gear, transmits the torque of the belt ring to the shaft. The shaft rotates around its axis, and through the meshing of the half-width gear and the rack, transmits the shaft torque to the rack. The protruding tooth root part and the concave die part slide along the slide groove away from the center of the tooth die, compressing the spring. The limiting spring contactes the limiting buckle to complete the energy storage. During stamping and hammer forging, the limiting buckle breaks through the limiting spring, the compressed spring recovers its deformation, and pushes the protruding tooth root part to impact the tooth root position of the tooth die, and the concave die part to impact the tooth peak position of the tooth die, increasing the deformation speed and pressure of the rough blank and ensuring that the metal fills the die cavity. This invention also designs a forging mechanism, through which the output end of the servo cylinder is displaced according to the electrical control signal of the control box. The output end of the servo cylinder is hinged to the bottom cylinder. The head rod deflects within the hemispherical cavity, adjusting the tilt angle of the pressure-dividing mechanism on the upper surface of the blank. In conjunction with the pressure-dividing mechanism, during the stamping of the upper surface of the blank, the first motor outputs a fixed-axis torque to the second gear rod, driving the conical disc to move closer to the head rod. During stamping, the outer cylinder contacts the blank first, and the first motor outputs a reverse torque to move the conical disc away from the head rod. The conical disc then contacts the blank, and the outer periphery stamps the blank first, causing the edges of the blank to converge inwards. The conical disc then contacts the blank, flattening the blank that has converged towards the center. This effectively eliminates the flash phenomenon of stamping and hammer forging, improving forging quality. This invention automates the cutting, heating, rough forging, and precision forging of gear parts. By using multiple fine-tuning zones for forging on the upper surface of the blank, it effectively eliminates the flash phenomenon of stamping and hammer forging, increases the deformation speed and pressure of the blank, ensures that the metal fills the die cavity, and significantly improves forging efficiency and quality.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1 , Figure 2 As shown, the present invention provides a technical solution for forging equipment and forging method for input shaft gears for new energy vehicles, including a base frame 1, a control box 2, a steering conveyor belt 3, a cutting machine 4, an electro-hydraulic hammer machine 5, a final forging mechanism 6, an electrically controlled sliding table 7, and a multi-axis robotic arm 8. The final forging mechanism 6 includes a gantry frame 61 and a base plate 64. The control box 2, steering conveyor belt 3, cutting machine 4, electro-hydraulic hammer machine 5, gantry frame 61, base plate 64, and electrically controlled sliding table 7 are all fixedly connected to the base frame 1. The multi-axis robotic arm 8 is fixedly connected to the electrically controlled sliding table 7. The steering conveyor belt 3, cutting machine 4, electro-hydraulic hammer machine 5, final forging mechanism 6, electrically controlled sliding table 7, and multi-axis robotic arm 8 are all connected to the control box 2 via electrical signals.

[0028] This invention relates to a forging device for input shaft gears in new energy vehicles. A steering conveyor belt 3 transports rolled billets to a cutting machine 4. According to the electrical control signal from the control box 2, the cutting machine 4 precisely cuts the billets to the required volume. A multi-axis robotic arm 8 transports the rough billet to an external heating furnace for heating. The multi-axis robotic arm 8 then transports the heated rough billet to an electro-hydraulic hammer press 5 for preliminary hammer forging. An electrically controlled sliding table 7 drives the multi-axis robotic arm 8 to move and transport the initially forged rough billet to a final forging mechanism 6. The final forging mechanism 6 precision forges the rough billet into a tooth shape. During precision forging, the final forging mechanism 6 performs multiple fine-tuning forging pressures on the upper surface of the rough billet in sections, while simultaneously punching the sides of the rough billet to increase the deformation speed and pressure of the rough billet, ensuring that the metal fills the die cavity, eliminating flash generated during forging, and significantly improving the forging quality.

[0029] like Figure 2 , Figure 3 As shown, the final forging mechanism 6 also includes a drive screw 62, a slide table 63, a drive motor 65, and a forging mechanism 69. The slide table 63 is provided with a threaded hole 631 and a through hole 632. The drive screw 62 and the threaded hole 631 are each provided in two sets. The drive screw 62 is rotatably connected to the gantry frame 61, and the drive screw 62 is threadedly connected to the threaded hole 631. The forging mechanism 69 includes a rotating shaft 691, a rotary motor 692, and a pressure dividing mechanism 697. The pressure dividing mechanism 697 includes a first motor 6978. The rotating shaft 691 is rotatably connected to the through hole 632, and the rotary motor 692 is fixedly connected to the slide table 63. The drive screw 62, the drive motor 65, the rotary motor 692, and the first motor 6978 are all connected to the control box 2 via electrical signals.

[0030] The electrically controlled sliding table 7 drives the multi-axis robotic arm 8 to move and transport the initial forging blank to the base plate 64. The drive screw 62 outputs a fixed-axis torque. Through the threaded connection between the drive screw 62 and the threaded hole 631, the slide table 63 moves downward along the drive screw 62, driving the pressure dividing mechanism 697 to perform stamping and hammering forging on the blank located on the toothed die 68. The rotary motor 692 drives the pressure dividing mechanism 697 to rotate, and the upper surface of the blank is subjected to multiple fine-tuning forging in sections.

[0031] like Figure 3 , Figure 4 As shown, the final forging mechanism 6 also includes a one-way pulley 66, a side punching mechanism 67, and a toothed die 68. The side punching mechanism 67 includes an annular housing 671, a belt ring 672, and a base platform 673. The drive motor 65, the annular housing 671, the base platform 673, and the toothed die 68 are all fixedly connected to the base plate 64. The output end of the drive motor 65 is unidirectionally rotatably connected to the one-way pulley 66. The one-way pulley 66 and the belt ring 672 are connected by belt drive. The belt ring 672 is rotatably connected to the annular housing 671.

[0032] Before the pressure dividing mechanism 697 performs stamping and hammer forging on the blank located on the die 68, the drive motor 65 outputs a fixed-axis torque to the one-way pulley 66. The output torque direction is opposite to the allowable rotation direction of the one-way pulley 66. The torque is transmitted to the belt ring 672 through the belt. The belt ring 672 rotates and the side punching mechanism 67 stores energy. At the same time, the side punching mechanism 67 counter-punches the die 68 to forge the side of the blank, thereby increasing the deformation speed and pressure of the blank and ensuring that the metal fills the die cavity.

[0033] like Figure 5 , Figure 6 As shown, the side punching mechanism 67 also includes a protruding tooth root part 674 and a concave die part 675. The base platform 673 is provided with a sliding groove 6731 and a limiting buckle 6732. The protruding tooth root part 674, the concave die part 675, the sliding groove 6731, and the limiting buckle 6732 are all provided in several groups. The several groups of protruding tooth root parts 674, concave die parts 675, sliding grooves 6731, and limiting buckles 6732 are all evenly distributed along the circumference of the ring shell 671. The protruding tooth root part 674 and the concave die part 675 are arranged adjacent to each other. The protruding tooth root part 674 and the concave die part 675 are slidably connected to the sliding groove 6731.

[0034] Several sets of protruding tooth root parts 674 and concave die parts 675, evenly distributed along the circumference of the ring shell 671, store energy before hammer forging. The protruding tooth root parts 674 and concave die parts 675 slide along the slide groove 6731 in a direction away from the center of the tooth mold 68. When the rough blank located on the tooth mold 68 is stamped and hammer forged, the protruding tooth root parts 674 and concave die parts 675 move in the opposite direction to the center. The protruding tooth root parts 674 impact the tooth root position of the tooth mold 68, and the concave die parts 675 impact the tooth peak position of the tooth mold 68, thereby increasing the deformation speed and pressure of the rough blank and ensuring that the metal fills the mold cavity.

[0035] like Figure 5 , Figure 6 As shown, the side impact mechanism 67 also includes a limiting spring 676, a rack 677, a shaft 678, and a compression spring 679. The limiting spring 676, rack 677, shaft 678, and compression spring 679 are provided in several groups. The several groups of limiting springs 676, racks 677, shafts 678, and compression springs 679 are evenly distributed along the circumference of the ring shell 671. The limiting springs 676, racks 677, and compression springs 679 are all fixedly connected to the tooth root member 674. The limiting spring 676 contacts the limiting buckle 6732. The compression spring 679 is fixedly connected to the ring shell 671. The shaft 678 is provided with a half-amplitude gear 6781 and an upper gear 6782. The belt ring 672 is provided with an internal gear ring 6721. The upper gear 6782 meshes with the tooth surface of the internal gear ring 6721. The half-amplitude gear 6781 meshes with the tooth surface of the rack 677.

[0036] The drive motor 65 transmits torque through the belt, driving the belt ring 672 to rotate. The rotation of the belt ring 672 meshes with the tooth surface of the upper gear 6782 through the internal gear ring 6721, transmitting the torque of the belt ring 672 to the shaft 678. The shaft 678 rotates around its axis, and through the tooth surface of the half-width gear 6781 meshing with the rack 677, the torque of the shaft 678 is transmitted to the rack 677. The protruding tooth root part 674 and the concave die part 675 slide along the slide groove 6731 away from the center of the tooth mold 68, compressing the spring 679. The limiting spring piece 676 contacts the limiting buckle 6732 to complete the energy storage. During stamping and hammer forging, the limiting buckle 6732 breaks through the limiting spring piece 676, and the compressed spring 679 recovers its deformation, pushing the protruding tooth root part 674 to impact the tooth root position of the tooth mold 68, and the concave die part 675 to impact the tooth peak position of the tooth mold 68, increasing the deformation speed and pressure of the blank, and ensuring that the metal fills the mold cavity.

[0037] like Figure 7 , Figure 8 As shown, the forging mechanism 69 also includes a first gear rod 693, a ball joint rod 694, a chassis 695, and a servo cylinder 696. The output end of the rotary motor 692 is fixedly connected to the first gear rod 693. The rotating shaft 691 is provided with a side tooth groove 6911 and a hemispherical cavity 6912. The first gear rod 693 meshes with the tooth surface of the side tooth groove 6911, and the ball joint rod 694 contacts the hemispherical cavity 6912. The chassis 695 is fixedly connected to the rotating shaft 691. The pressure dividing mechanism 697 also includes an outer cylinder 6971 and a bottom cylinder 6972. The outer cylinder 6971 is fixedly connected to both the ball joint rod 694 and the bottom cylinder 6972. The servo cylinder 696 is hinged to the chassis 695, and the output end of the servo cylinder 696 is hinged to the bottom cylinder 6972.

[0038] The rotary motor 692 outputs a fixed-axis torque to the first gear rod 693. Through the meshing of the teeth between the first gear rod 693 and the side tooth groove 6911, the torque of the rotary motor 692 is transmitted to the rotating shaft 691. The rotating shaft 691 rotates around its axis in the through hole 632. The output end of the servo cylinder 696 is displaced according to the electrical control signal of the control box 2. The output end of the servo cylinder 696 is hinged to the bottom cylinder 6972. The ball head rod 694 deflects in the hemispherical cavity 6912 to adjust the tilt angle of the upper surface of the stamping blank by the pressure dividing mechanism 697.

[0039] like Figure 7 , Figure 8As shown, the pressure dividing mechanism 697 also includes a conical disc 6973, a connecting rod 6974, a sliding disc 6975, a second gear rod 6976, and a gear frame 6977. The connecting rod 6974 is fixedly connected to both the conical disc 6973 and the sliding disc 6975. The conical disc 6973 is in contact with the bottom cylinder 6972. The sliding disc 6975 is slidably connected to the outer cylinder 6971. The gear frame 6977 is fixedly connected to the sliding disc 6975. The first motor 6978 is fixedly connected to the outer cylinder 6971. The output end of the first motor 6978 is fixedly connected to the second gear rod 6976. The second gear rod 6976 meshes with the tooth surface of the gear frame 6977.

[0040] When stamping the upper surface of the blank, the first motor 6978 outputs a fixed-axis torque to the second gear rod 6976. The torque is transmitted through the meshing of the teeth between the second gear rod 6976 and the gear frame 6977. The slide 6975 drives the conical disc 6973 to move closer to the ball head rod 694. During stamping, the outer cylinder 6971 contacts the blank first. The first motor 6978 outputs a reverse torque to move the conical disc 6973 away from the ball head rod 694. The conical disc 6973 then contacts the blank. The outer edge of the blank is stamped first, causing the edge of the blank to gather inward. The conical disc 6973 then contacts the blank, flattening the blank that is gathering towards the center. This can effectively eliminate the flash phenomenon of stamping and hammer forging and improve the forging quality.

[0041] like Figure 1 As shown, the forging method includes the following steps: 1) The turning conveyor belt 3 transports the billet to the cutting machine 4 for cutting: The turning conveyor belt 3 transports the rolled billet to the cutting machine 4. According to the electrical control signal of the control box 2, the cutting machine 4 accurately cuts the billet to the required volume.

[0042] 2) Multi-axis robotic arm 8 transports the blank to the heating furnace: Multi-axis robotic arm 8 transports the blank to the external heating furnace for heating.

[0043] 3) The multi-axis robotic arm 8 places the heated billet into the electro-hydraulic hammer 5 for initial forging: The multi-axis robotic arm 8 transports the heated billet to the electro-hydraulic hammer 5 to complete the initial hammer forging.

[0044] 4) The multi-axis robotic arm 8 transports the pre-forged billet to the final forging mechanism 6 to complete the final precision forging: the electrically controlled sliding table 7 drives the multi-axis robotic arm 8 to move and transport the pre-forged billet to the final forging mechanism 6, and the final forging mechanism 6 precision forges the billet into a tooth shape.

[0045] The working principle of this invention: The steering conveyor belt 3 transports the rolled billet to the cutting machine 4, which precisely cuts the billet to the required volume. The multi-axis robotic arm 8 transports the rough billet to an external heating furnace for heating. The multi-axis robotic arm 8 then transfers the heated rough billet to an electro-hydraulic hammer press 5 for preliminary hammer forging. The electrically controlled sliding table 7 drives the multi-axis robotic arm 8 to move and transport the initially forged rough billet to the final forging mechanism 6. The final forging mechanism 6 precision forges the rough billet into a toothed shape. During precision forging, the final forging mechanism 6 performs multiple fine-tuning forging operations on the upper surface of the rough billet in zones. The rotary motor 692 drives the rotating shaft 691 to... The servo cylinder 696 outputs a displacement signal from the control box 2, causing the ball joint 694 to deflect within the hemispherical cavity 6912. This adjusts the tilt angle of the pressure-dividing mechanism 697 on the upper surface of the blank. The first motor 6978 drives the slide 6975 to move the conical disc 6973 closer to the ball joint 694. During stamping, the outer cylinder 6971 contacts the blank first. The first motor 6978 outputs a reverse torque to move the conical disc 6973 away from the ball joint 694, allowing it to contact the blank later. The outer periphery stamps the blank first, making the blank... As the edges converge inward, the conical disc 6973 contacts the blank, flattening the blank that is converging towards the center. This effectively eliminates the flash phenomenon during stamping and hammer forging. Before the pressure-distributing mechanism 697 performs stamping and hammer forging on the blank located on the die 68, the drive motor 65 transmits torque through the belt, driving the belt ring 672 to rotate. Through the meshing of the inner gear ring 6721 and the upper gear 6782, the torque of the belt ring 672 is transmitted to the shaft 678. The shaft 678 rotates around its axis. The meshing of the half-width gear 6781 and the rack 677 transmits the rotation of the shaft 678. The toothed rack 677, the tooth root part 674, and the die part 675 slide along the slide groove 6731 away from the center of the tooth die 68, compressing the spring 679. The limiting spring piece 676 contacts the limiting buckle 6732 to complete energy storage. During stamping and hammer forging, the limiting buckle 6732 breaks through the limiting spring piece 676, and the compression spring 679 recovers its deformation and pushes the tooth root part 674 to impact the tooth root position of the tooth die 68, and the die part 675 to impact the tooth peak position of the tooth die 68. This increases the deformation speed and pressure of the blank, ensures that the metal fills the die cavity, and greatly improves the forging quality.
