Description

Technical Field

[0001] This application belongs to the field of forging die technology, and in particular relates to a tube sleeve forging die and a forging production line. Background Technology

[0002] Forging dies are used to shape materials at high temperatures and are widely used in industrial production. Forging dies consist of an upper die, a lower die, and a female die. The lower die and the female die are combined to form a forming cavity for holding the material to be formed. The upper die is pressed into the forming cavity under the drive of a hydraulic press, causing the material to be formed (the blank) to be plastically deformed into the formed material (the sleeve).

[0003] However, during this process, the flow resistance or speed of the material to be formed may vary in different areas of the forming cavity, which may cause the area on the upper surface of the material to be formed to flow faster to form bulges or wrinkles, affecting the quality of the product after forming. At the same time, after forging, the material to be formed is usually in close contact with the inner wall of the forming cavity (especially the female mold), and the clamping force generated by cooling and shrinkage may cause the material to get stuck in the mold and be difficult to remove smoothly and without damage.

[0004] The key technical problem to be solved is how to improve the quality of the product after the material to be formed is processed throughout the forging process. Utility Model Content

[0005] This application aims to address at least the shortcomings of existing technologies in improving the quality of the product after forging the material being formed throughout the entire forging process. To this end, this application proposes a forging die for a tube sleeve.

[0006] In a first aspect, this application provides a forging die, including: an upper die assembly, an upper die driving mechanism, a lower die, a female die assembly, and a female die driving mechanism; The female mold assembly includes a first female mold part and a second female mold part. The first female mold part and the second female mold part are adapted to abut against the periphery of the lower mold and can be enclosed with the lower mold to form a molding cavity. The molding cavity is used to place the material to be molded. The upper mold drive mechanism is connected to the upper mold assembly for moving the upper mold assembly between a first position and a second position; when the upper mold assembly is in the first position, one end of the upper mold assembly is placed inside the molding cavity, and the end face of the other end of the upper mold assembly abuts against the upper surface of the material to be molded; when the upper mold assembly is in the second position, one end of the upper mold assembly is outside the molding cavity; The female mold driving mechanism is connected to the first female mold part and the second female mold part for driving the first female mold part and the second female mold part away from each other when the upper mold assembly is in the second position.

[0007] According to one embodiment of this application, the upper mold assembly includes a leveling sleeve and an upper mold, wherein the upper mold is disposed in the middle of the leveling sleeve; When the upper mold assembly is in the first position, the portion of the upper mold outside the leveling sleeve is placed inside the molding cavity, and the flat surface of the leveling sleeve abuts against the upper surface of the material to be molded.

[0008] According to one embodiment of this application, the portion of the upper mold outside the leveling sleeve abuts against the lower mold.

[0009] According to one embodiment of this application, the first female mold portion and the second female mold portion being far apart from each other includes the first female mold portion and the second female mold portion being far apart from each other in a direction perpendicular to the lower mold; or, the first female mold portion and the second female mold portion being deflected away from each other around the lower mold.

[0010] According to one embodiment of this application, the female mold driving mechanism includes a first drive motor and left and right rotating lead screws; The output end of the first drive motor is fixedly connected to the left and right rotating lead screws. The left-hand end of the left and right rotating lead screws is threadedly connected to the first female mold part, and the right-hand end of the left and right rotating lead screws is threadedly connected to the second female mold part.

[0011] According to one embodiment of this application, it further includes: a flipping mechanism; The flipping mechanism includes a driving part and a rotating part. The two opposite end faces of the rotating part are provided with mounting grooves. The lower mold, the female mold assembly and the female mold driving mechanism are all located in the mounting grooves. The driving part is connected to the rotating part for driving the rotating part to rotate so that the opening of the mounting slot is vertically upward and then rotates to be vertically downward.

[0012] According to one embodiment of this application, the rotating part is a barrel structure, and there are multiple mounting slots, which are arranged around the rotating part.

[0013] According to one embodiment of this application, the drive unit includes a frame and a second drive motor; the housing of the second drive motor is mounted on the frame, and the output end of the second drive motor is fixedly connected to the center of the rotating part.

[0014] According to one embodiment of this application, stabilizing disks are also installed on both sides of the frame, and arc-shaped tracks are provided on the stabilizing disks. Rollers are also installed on both sides of the rotating part. The number of rollers on one side of the rotating part is the same as the number of mounting slots, and the rollers are tactilely connected to the arc-shaped tracks.

[0015] Secondly, this application provides a forging production line, which includes: a tube sleeve forging die, a manipulator for gripping the material to be formed, and a conveyor belt for forming the material; The manipulator for gripping the material to be formed is located on one side of the tube forging die, and is used to grip and place the material to be formed into the forming cavity when the upper die assembly is in the second position. The molding material conveyor belt is located directly below the rotating part and is used to receive the molding material falling from the molding cavity when the first female mold part and the second female mold part are far apart.

[0016] Beneficial effects: This application achieves uniform control of the flow of material to be formed during the forging process, effectively eliminating surface wrinkles and defects. After forming, the active separation of the first and second female molds makes it easier to remove the material from the forming cavity, avoiding damage caused by forced demolding and improving product quality. This solution is particularly suitable for the precision forging of thin-walled tubular parts, solving the technical bottlenecks of difficult demolding and uncontrollable surface quality in traditional processes.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] In existing technologies, forging dies are widely used in the forming and processing of high-temperature materials. Traditional dies consist of an upper die, a lower die, and a fixed female die. The lower die and the female die together form a forming cavity for placing the material to be formed (the blank). A hydraulic press drives the upper die to press into the forming cavity, causing the material to be formed to undergo plastic deformation.

[0022] However, differences in flow resistance in different areas of the material during molding can easily lead to wrinkles or bulges on the upper surface, affecting the surface quality of the product. After molding, the material shrinks due to cooling and generates a clamping force against the inner wall of the mold, often causing it to become stuck in the female mold and difficult to demold. External force is required to knock or eject the material, which can easily damage the product.

[0023] To address the aforementioned issues and the problem of uneven material flow leading to surface defects, it is necessary to optimize the mold structure to improve material flow during the molding process. Considering that the female mold in traditional molds has a fixed structure and cannot actively adjust the shape of the molding cavity, if the shape of the female mold can be controlled synchronously during the upper mold pressing process, it may be possible to achieve uniform material flow and improve product surface quality. Regarding the difficulty in demolding, existing technologies often employ ejection mechanisms or hammering methods, but these can easily damage the product. It is worth exploring ways to achieve natural demolding through changes in the mold structure during the mold opening stage.

[0024] like Figures 1-7 As shown, this application proposes an upper mold assembly 10, an upper mold drive mechanism, a lower mold 30, a female mold assembly 40, and a female mold drive mechanism 50.

[0025] The female mold assembly 40 includes a separable first female mold portion 41 and a second female mold portion 42, which together with the lower mold 30 form a molding cavity a. An upper mold drive mechanism controls the upper mold assembly 10 to move between a first position and a second position. In the first position, one end of the upper mold assembly 10 is placed inside the molding cavity a and in contact with the material to be molded b. In the second position, it is completely withdrawn from the molding cavity a. After the upper mold assembly 10 withdraws, the female mold drive mechanism 50 drives the two female mold portions to move away from each other.

[0026] The upper mold assembly 10 refers to a moving part with a pressing function. One end of the upper mold assembly 10 is inserted into the molding cavity a to form the inner cavity of the material b to be molded; the other end of the upper mold assembly 10 is used to contact and press the upper surface of the material b to be molded. The upper mold drive mechanism refers to a power device that controls the position change of the upper mold 12, such as a hydraulic cylinder or a servo motor, which achieves precise displacement through a linear guide rail. The lower mold 30 refers to a base component that fixes and supports the material b to be molded. The female mold assembly 40 refers to a separable lateral molding component, such as composed of a first female mold part 41 and a second female mold part 42, which achieves opening and closing movement through a sliding rail. The female mold drive mechanism 50 refers to a transmission device that controls the separation of the first female mold part 41 and the second female mold part 42, such as using a bidirectional screw or linkage mechanism, to achieve synchronous reverse or synchronous forward movement of the first female mold part 41 and the second female mold part 42.

[0027] like Figure 1 and Figure 4 As shown in the above embodiment of this application, one end of the upper mold assembly 10 is inserted into the molding cavity a to form the inner cavity of the material to be molded b. At the same time, the other end of the upper mold assembly 10 is used to contact and press the upper surface of the material to be molded to eliminate wrinkles or bulges formed on the upper surface of the material to be molded b during the molding process, so that the upper surface of the final molded material b is flat. After forging, compared with existing technologies, traditional molds have a fixed overall structure for the female mold, making it impossible to actively adjust the shape of the forming cavity a. In this application, the upper mold drive mechanism lifts the upper mold assembly 10 to the second position, completely exiting the forming cavity a. At this time, the female mold drive mechanism 50 is activated, causing the first female mold part 41 and the second female mold part 42 to separate horizontally, expanding the space of the forming cavity a. Because the active separation of the female mold eliminates the clamping effect on the forming material b, it makes it easier to remove the forming material b from the forming cavity a.

[0028] In summary, through the above technical solution, this application achieves uniform control of the flow of the material to be formed during the forging process, effectively eliminating surface wrinkles and defects. After forming, the active separation of the first female mold part 41 and the second female mold part 42 makes it easier to remove the material from the forming cavity a, avoiding damage caused by forced demolding and improving product quality. This solution is particularly suitable for the precision forging of thin-walled tubular parts, solving the technical bottlenecks of difficult demolding and uncontrollable surface quality in traditional processes.

[0029] like Figures 1-3 As shown, in some embodiments, the upper mold assembly 10 includes a leveling sleeve 11 and an upper mold 12, wherein the upper mold 12 passes through the middle of the leveling sleeve 11; When the upper mold assembly 10 is in the first position, the portion of the upper mold 12 outside the leveling sleeve 11 is placed inside the molding cavity a, and the flat surface of the leveling sleeve 11 abuts against the upper surface of the material to be molded.

[0030] The leveling sleeve 11 is an annular structure fitted outside the upper die 12. It can be made of metal to form an annular sleeve, with its inner diameter matching the outer diameter of the upper die 12. The lower end face of the leveling sleeve 11 is machined into a flat surface to apply uniform pressure to the upper surface of the material to be formed during the forging process. The upper die 12 is a columnar structure used to forge the material to be formed within the forming cavity a. It can be made of a high-hardness alloy material, with its outer diameter slightly smaller than the lateral dimension of the forming cavity a to guide the material flow direction during forging.

[0031] In this embodiment, when the upper die assembly 10 moves to the first position, the end of the upper die 12 enters the forming cavity a and applies axial pressure to the material to be formed. At this time, the flat surface of the leveling sleeve 11 simultaneously presses against the upper surface of the material to be formed. The flat area covered by the leveling sleeve 11 is larger than the cross-sectional area of ​​the upper die 12, thus constraining the edge area of ​​the upper surface of the material during the forging process and suppressing bulging or wrinkling of the material to be formed due to differences in flow velocity. The synergistic effect of the upper die 12 and the leveling sleeve 11 ensures that the surface of the material to be formed remains flat during axial compression and radial expansion.

[0032] In practice, this application further proposes that the portion of the upper mold 12 outside the leveling sleeve 11 abuts against the lower mold 30, so that when the end of the upper mold 12 is inserted into the molding cavity a, the resulting inner cavity of the material to be molded is a through hole. Of course, it should also be permitted if the portion of the upper mold 12 outside the leveling sleeve 11 does not abut against the lower mold 30, and when the end of the upper mold 12 is inserted into the molding cavity a, the resulting inner cavity of the material to be molded is a groove.

[0033] In some embodiments, the first female mold portion 41 and the second female mold portion 42 being far apart from each other includes the first female mold portion 41 and the second female mold portion 42 being far apart from each other in a direction perpendicular to the lower mold 30.

[0034] The mutual separation in the direction perpendicular to the lower mold 30 refers to the linear separation movement of the female mold assembly 40 along a plane perpendicular to the axis of the lower mold 30. This can be achieved by using a hydraulic push rod or a linear guide mechanism, thereby expanding the lateral space of the molding cavity a through linear displacement.

[0035] Specifically, when the female mold drive mechanism 50 performs the vertical separation action, the first female mold part 41 and the second female mold part 42 move symmetrically in the horizontal direction, so that the side wall of the molding cavity a forms a uniformly enlarged demolding gap.

[0036] like Figures 5-7 As shown, this application further proposes a female mold driving mechanism 50 including a first drive motor 51 and a left-hand and right-hand screw 52; the output end of the first drive motor 51 is fixedly connected to the left-hand and right-hand screw 52, ​​the left-hand end of the left-hand and right-hand screw 52 is threadedly connected to the first female mold part 41, and the right-hand end of the left-hand and right-hand screw 52 is threadedly connected to the second female mold part 42.

[0037] The left-hand and right-hand lead screw 52 refers to a lead screw with a left-hand threaded section and a right-hand threaded section. Specifically, it can be implemented using a metal rod with a double-ended anti-directional thread structure. The left-hand end and the right-hand end have opposite thread directions, so that when the lead screw rotates, it can drive the female mold parts connected on both sides to move synchronously in opposite directions. The first drive motor 51 is a device that provides rotational power. Specifically, it can be implemented using a servo motor or a stepper motor. It is fixedly connected to the lead screw through its output end to transmit torque, thereby controlling the forward and reverse rotation of the lead screw.

[0038] Specifically, when it is necessary to move the first female mold part 41 and the second female mold part 42 away from each other, the first drive motor 51 drives the left and right helical screws 52 to rotate. Since the left-hand end is threaded to the first female mold part 41 and the right-hand end is threaded to the second female mold part 42, when the screw rotates, the first female mold part 41 moves along the left-hand thread direction and the second female mold part 42 moves along the right-hand thread direction. The two move synchronously in opposite directions in the axial direction of the screw, thereby achieving rapid separation of the female mold parts.

[0039] In some embodiments, the tube sleeve forging die further includes: a flipping mechanism 60; The flipping mechanism 60 includes a driving part 61 and a rotating part 62. The two opposite ends of the rotating part 62 are provided with mounting grooves 621. The lower mold 30, the female mold assembly 40 and the female mold driving mechanism 50 are all disposed in the mounting grooves 621. The driving part 61 is connected to the rotating part 62 for driving the rotating part 62 to rotate so that the opening of the mounting groove 621 is vertically upward and then rotates to be vertically downward.

[0040] The flipping mechanism 60 is a device used to change the spatial position of the mold. It can be implemented using a structure where a motor and a rotating shaft work together, changing the direction of the mold opening through rotation. The rotating part 62 is a rotatable component that supports the mold assembly. It can be implemented using a barrel-shaped or disc-shaped structure, with a mounting groove 621 on its end face for fixing the lower mold 30 and the female mold assembly 40. The drive part 61 is a component that provides rotational power. It can be implemented using a servo motor or a hydraulic motor, connected to the rotating part 62 via a drive shaft. The mounting groove 621 is a recessed structure for accommodating the mold assembly. It can be implemented using a rectangular or circular cross-section groove, with the groove opening direction changing as the rotating part 62 rotates.

[0041] Specifically, after the upper mold assembly 10 moves to the second position and disengages from the molding cavity a, the drive unit 61 drives the rotating unit 62 to rotate around the axis, causing the opening of the mounting groove 621 to gradually change from vertically upward to vertically downward. At this time, the molding material b naturally detaches from the molding cavity a under the action of gravity, without the need for manual intervention or an additional ejection mechanism. During the rotation, the female mold drive mechanism 50 synchronously controls the female mold assembly 40 to remain open, avoiding obstruction of material detachment. This process can be integrated with automated production lines to achieve continuous operation, for example, by setting up a conveyor belt below the rotating unit 62 to receive the dropped material.

[0042] Compared to existing technologies, traditional molds rely on ejector pins or hammering to remove the workpiece during demolding, which can easily damage the product surface and is inefficient. By setting up a rotatable mold support structure, automatic demolding is achieved using gravity, which avoids the squeezing damage to the molded material b caused by mechanical ejection devices and simplifies the mold structure. At the same time, the rotation action can be linked with the preceding and following processes, improving the overall cycle time of the production line.

[0043] Through the above technical solution, this application effectively solves the problem of difficult demolding of the molded material b due to clamping force, and realizes non-destructive automatic unloading. The introduction of the rotating structure enables the mold to quickly change the station state, cooperate with automated equipment to complete continuous production, significantly improve processing efficiency and reduce the risk of manual operation. The directional rotation function of the mounting slot 621 ensures that the molded material b falls accurately into the designated collection position, avoiding production line chaos caused by material scattering.

[0044] This application further proposes that the rotating part 62 is a barrel structure, and that there are multiple mounting slots 621, with the multiple mounting slots 621 arranged around the rotating part 62.

[0045] The barrel structure refers to the rotating part 62 with a cylindrical or near-cylindrical outer contour, which can be made of a hollow cylinder formed by metal casting or welding, with multiple recessed areas evenly distributed circumferentially on its outer surface. The mounting groove 621 refers to the accommodating space for fixing the lower mold 30, the female mold assembly 40, and the drive mechanism. It can be achieved by machining rectangular or arc-shaped grooves on the outer wall of the rotating part 62, with the depth and width of each groove matching the installation dimensions of the mold assembly. Multiple mounting grooves 621 distributed circumferentially along the rotating part 62 means that the grooves are arranged in a circular array around the rotation axis. For example, the included angle between adjacent grooves can be 60 degrees or 90 degrees, and the specific number can be adjusted according to production needs.

[0046] Specifically, when the rotating part 62 rotates around its own axis, multiple mounting slots 621 can sequentially enter the forging station. For example, when a mounting slot 621 is in a vertically upward position, the lower die 30 and the female die assembly 40 inside it can complete material forming; at the same time, other mounting slots 621 can be in the cooling, demolding, or loading stage. The continuous rotation of the rotating part 62 can realize multi-station continuous operation. For example, after a mounting slot 621 completes forging, the rotating part 62 rotates at a certain angle to allow the next mounting slot 621 to enter the forging station, and the formed material b in the original station can automatically fall off when the rotating part 62 rotates to a downward position.

[0047] Compared with existing technologies, traditional forging dies typically employ a fixed single-station structure, requiring the machine to be stopped and the workpiece removed after each forging operation, thus limiting production efficiency. This solution, however, utilizes the barrel-like structure of the rotating part 62 and multiple circumferentially distributed mounting slots 621 to enable continuous switching of the die's stations, achieving parallel operations of forging, demolding, and loading, significantly shortening the production cycle time.

[0048] Through the above technical solution, this application solves the problem that the molded material b is difficult to demold due to the clamping force. When the rotating part 62 rotates and the groove opening of the mounting groove 621 faces downward, the molded material b automatically detaches from the mold under the action of gravity, avoiding damage caused by manual intervention. At the same time, the multi-station design allows the forging process to be carried out simultaneously with other processes, effectively improving the overall efficiency of the production line.

[0049] This application further proposes that the drive unit 61 includes a frame 611 and a second drive motor 612. The housing of the second drive motor 612 is mounted on the frame 611, and the output end of the second drive motor 612 is fixedly connected to the center of the rotating part 62. Stabilizing disks 6111 are also mounted on both sides of the frame 611, and arc-shaped tracks are provided on the stabilizing disks 6111. Rollers 622 are also mounted on both sides of the rotating part 62. The number of rollers 622 on one side of the rotating part 62 is the same as the number of mounting slots 621, and the rollers 622 are tactilely connected to the arc-shaped tracks.

[0050] The frame 611 refers to the main support structure that supports the drive unit 61 and the rotating unit 62. It can be implemented using a welded steel frame or a cast frame, and its function is to provide a stable mounting base for the rotational motion. The second drive motor 612 is the power source that drives the rotating unit 62 to rotate around its central axis. It can be implemented using a servo motor or a stepper motor, and its output end is directly connected to the center of the rotating unit 62 to achieve precise rotation of the rotating unit 62 around its axis. The stabilizing disk 6111 refers to the annular support component fixed on both sides of the frame 611. It can be implemented using a cast iron disk with an arc-shaped track, and its function is to provide radial constraint for the rotating unit 62. The arc-shaped track is a guide structure extending along the circumference, and can be in the form of a grooved or raised track. It works in conjunction with the roller 622 to limit the movement trajectory of the rotating unit 62. Rollers 622 refer to rolling components installed on both sides of the rotating part 62. Specifically, they can be steel rollers 622 supported by bearings. Their number corresponds to the number of mounting slots 621, ensuring that each mounting slot 621 has rollers 622 in contact with the track when it rotates to a specific angle, thereby evenly distributing the load of the rotating part 62.

[0051] Specifically, the second drive motor 612 drives the rotating part 62 to rotate around the central axis via its output end, causing the mounting slot 621 to sequentially reach either a vertically upward or downward position. The stabilizing disk 6111, through the rolling engagement of its two arc-shaped tracks and rollers 622, restricts radial offset of the rotating part 62 during rotation. When the rotating part 62 rotates, the rollers 622 roll along the arc-shaped tracks, forming a guiding constraint for the circular motion, preventing rotational eccentricity caused by uneven weight distribution of the mold and materials within the mounting slot 621. For example, during the process of the rotating part 62 driving the mounting slot 621 from a vertically upward to a downward position, the contact point between the rollers 622 and the tracks moves with the angle, ensuring that the rotating part 62 remains within the support range provided by the stabilizing disk 6111.

[0052] Compared with existing technologies, the flipping mechanism 60 of traditional forging dies typically relies solely on the central shaft for rotation, lacking constraints on the radial displacement of the rotating part 62. This makes it prone to rotational deviation due to uneven die weight or material distribution, which in turn leads to positioning deviation or rotational jamming of the mounting slot 621. This solution, through the cooperation of the stabilizing disc 6111 and the track of the roller 622, forms a symmetrical rolling support structure on both sides of the rotating part 62, maintaining rotational freedom while effectively suppressing radial deviation, thereby improving the flipping positioning accuracy and operational stability.

[0053] Through the above technical solution, this application solves the positioning deviation problem caused by uneven force during the rotation of the rotating part 62, ensuring that the mounting groove 621 is accurately aligned with the conveyor belt of the forming material b when vertically downward, and avoiding transmission failures caused by the falling position deviation of the forming material b. At the same time, the rolling friction between the roller 622 and the track replaces the sliding friction, reducing drive energy consumption and component wear, and extending the service life of the equipment.

[0054] This application further proposes that the frame 611 is equipped with stabilizing disks 6111 on both sides, the stabilizing disks 6111 are provided with arc-shaped tracks, and the rotating part 62 is equipped with rollers 622 on both sides. The number of rollers 622 on one side of the rotating part 62 is the same as the number of mounting slots 621, and the rollers 622 are tactilely connected to the arc-shaped tracks.

[0055] The stabilizing disc 6111 refers to the disc-shaped support structure fixed on both sides of the frame 611. Specifically, it can be implemented as a metal disc with arc-shaped grooves, used to limit the movement trajectory of the rotating part 62. The arc-shaped track refers to the curved guide structure set along the edge of the stabilizing disc 6111. Specifically, it can be implemented as a grooved or raised track matching the shape of the roller 622, used to guide the rotating part 62 to rotate stably around the axis. The roller 622 refers to the rolling components installed on both sides of the rotating part 62. Specifically, it can be implemented as a metal wheel with bearings, and its number is consistent with the number of mounting slots 621, so that the rotation angle corresponding to each mounting slot 621 can be synchronously constrained by the roller 622, thereby reducing the risk of deviation during rotation.

[0056] Specifically, when the rotating part 62 is driven to rotate by the driving part 61, the rollers 622 roll along the arc-shaped track of the stabilizing disk 6111. The number of rollers 622 on both sides of the rotating part 62 is the same as the number of mounting slots 621, so that the rotation angle corresponding to each mounting slot 621 is synchronously limited by the rollers 622. In this process, the rolling contact between the rollers 622 and the arc-shaped track can reduce the frictional resistance between the rotating part 62 and the frame 611. At the same time, through the constraint of the track on the rollers 622, radial displacement or vibration of the rotating part 62 during rotation is avoided, ensuring that the molding material b in the molding cavity a can be stably released by gravity when it rotates to a vertically downward position.

[0057] In some specific embodiments, the arc-shaped track of the stabilizing disk 6111 can be designed as a semi-circular groove concentric with the rotation axis of the rotating part 62, and the roller 622 is embedded in the groove and rolls; the diameter of the roller 622 can be, for example, 50-100 mm, to match the radius of curvature of the track. The number of mounting slots 621 can be, for example, four, evenly distributed around the rotating part 62, and the corresponding number of rollers 622 is also four, located symmetrically on both sides of the rotating part 62.

[0058] Compared with existing technologies, the rotating mechanism of existing molds usually lacks constraints on the motion trajectory of the rotating part 62, which easily leads to shaking or deviation during rotation, affecting the stability of demolding of the molded material b. This solution, through the cooperation of the stabilizing plate 6111 and the roller 622, synchronously constrains the motion trajectory of the rotating part 62 when it rotates, avoiding deviation problems caused by inertia or uneven load, thereby improving the reliability of the demolding process.

[0059] Through the above technical solution, this application can ensure that the rotating part 62 remains stable during rotation, avoid the problem of the molding material b getting stuck or not falling off completely due to vibration or deviation, and at the same time reduce the wear of the rotating mechanism caused by friction, improve the service life of the mold and production efficiency.

[0060] This application further proposes a forging production line, including a tube forging die, a manipulator for gripping the material to be formed, and a conveyor belt for forming material b; the manipulator for gripping the material to be formed is disposed on one side of the tube forging die, for gripping the material to be formed and placing it in the forming cavity a when the upper die assembly 10 is in the second position, and then the upper die assembly 10 moves from the second position to the first position to forge the material to be formed. The molding material b conveyor belt is located directly below the rotating part 62. It is used to receive the molding material b falling from the molding cavity a when the rotating part 62 rotates so that the opening of the mounting groove 621 is vertically upward and then rotates to be vertically downward, and at the same time the first female mold part 41 and the second female mold part 42 move away from each other.

[0061] The material-to-be-formed gripper refers to an automated device capable of automatically grasping and positioning the material to be formed, b. Specifically, it can be implemented using a multi-joint robotic arm in conjunction with a vacuum suction cup or gripper. Its function is to replace manual operation and avoid uneven filling of the forming cavity a due to positioning deviations during the handling of high-temperature materials. The material-to-be-formed b conveyor belt refers to a conveying device with continuous conveying function. Specifically, it can be implemented using a belt conveyor or a chain conveyor. Its position is coordinated with the flipping action of the rotating part 62, enabling it to directly receive and transfer the material after it leaves the forming cavity a, avoiding surface scratches or deformation caused by manual handling.

[0062] Compared with existing technologies, current forging production lines typically rely on manual labor or simple mechanical devices for material placement and removal, resulting in low positioning accuracy, poor material handling efficiency, and easy damage to the material surface. This solution introduces a gripping robot and a conveyor belt working in tandem, combined with the flipping action of the rotating part 62, to achieve fully automated control of the entire process from material placement to removal. This avoids fluctuations in forming quality caused by manual intervention. At the same time, the combination of gravity demolding and conveyor belt support effectively solves the problem of jamming caused by clamping force on the formed material b.

[0063] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
