Description

Technical Field

[0001] The present invention relates to a flanging device for a slotted bushing, belonging to the technical field of aerospace component processing. Background Art

[0002] The slotted bushing is a commonly used component for fatigue strengthening of mounting holes on aircraft. It mainly uses cold extrusion strengthening technology, which has the characteristics of large interference, strong operability, and obvious extrusion effect. It can significantly improve the fatigue life of various material structures. With the advancement of the localization of slotted bushings, domestic slotted bushings are increasingly widely used and have achieved good usage effects.

[0003] One end of the slotted bushing is provided with a flanging structure, which is convenient for installation and disassembly. Flanging is a key process for the slotted bushing, that is, using a mold and stamping process to turn the hole end edge or outer edge of the cylindrical semi-finished slotted bushing into a straight edge or bevel edge facing outward. The components processed by the flanging process can have good rigidity. At present, domestic flanging processing of slotted bushings mainly uses a punching press and a customized mold for stamping processing. Due to the lack of automated equipment, manual processing is still relied on in the prior art, resulting in low efficiency. In addition, most of the existing flanging molds are of a fixed structure, that is, a mold cavity adapted to the slotted bushing product is provided in the flanging mold, and the slotted bushing to be flanged is placed in the mold cavity, and the end flanging of the slotted bushing is achieved by cooperating with stamping or pressing. This kind of flanging mold needs to be completely matched with the specifications of the slotted bushing to be processed, and the outer diameter size and height size of the slotted bushing need to be considered. Slotted bushings with the same outer diameter size may have various different height sizes, and it is not applicable to slotted bushings with different height size specifications. For slotted bushings with different height sizes, the corresponding flanging molds need to be replaced as a whole, with poor applicability and being not conducive to actual use. The overall replacement of the flanging mold will also increase the cost of the flanging mold. Summary of the Invention

[0004] The present invention aims at the defects of the prior art and provides a flanging device for a slotted bushing.

[0005] The technical solution for the present invention to solve the above technical problems is as follows: A flanging device for a slotted bushing, comprising a frame, and further comprising a feeding device, a mold, a mold conveying assembly, a stamping device, and a discharging assembly; the feeding device feeds the bushing into the mold, the mold conveying assembly is arranged on the frame, and the mold conveying assembly circulates the mold in sequence on the feeding device, the stamping device, and the discharging assembly; The feeding device includes a pushing component and a flipping component; the pushing component includes a material blocking mechanism and a pushing mechanism. The material blocking mechanism is used to block the bushings, and the pushing mechanism is used to push the bushings blocked by the material blocking mechanism to the flipping component; the flipping component includes a flipping base, on which a flipping plate is rotatably provided. The flipping plate is provided with a material receiving plate, a material pressing mechanism and a blanking mechanism. The material receiving plate is used to support the bushings. The material pressing mechanism includes a material pressing member, which is movably installed on the flipping plate and is used to press the bushings supported on the material receiving plate. The blanking mechanism includes a blanking plate, which is movably installed on the flipping plate and is used to push the bushings to be blanked into the mold after the flipping plate is flipped; The mold includes a forming mold base and a support component arranged in the forming mold base. The forming mold base is provided with a flanging mold inner cavity for forming the bushings and a support accommodating cavity for accommodating the support component. The flanging mold inner cavity is arranged above the support accommodating cavity; the support component includes a support seat, a support pad and a support spring. The support seat includes a base and a top rod arranged on the base. The support pad is slidably sleeved on the top rod. The support spring is sleeved on the top rod between the base and the support pad. A positioning groove for positioning the lower end of the bushing is formed by the cooperation between the support pad and the top rod.

[0006] The beneficial effects of the present invention are as follows: First, the feeding device of the present invention realizes the blocking and feeding of the bushings through the pushing component, feeds the bushings to the flipping component. The flipping component realizes the fixation of the bushings through the material receiving plate and the material pressing mechanism, flips the bushings in place through the flipping plate, and pushes the bushings into the mold through the blanking plate, thus realizing the automatic feeding of the bushings, eliminating the need for manual feeding and improving the processing efficiency.

[0007] Second, in the mold of the present invention, the upper end of the support spring acts on the support pad, and the lower end acts on the base. The top rod and the support pad cooperate to form a positioning groove for positioning the split bushing, ensuring that the bushing to be flanged is placed in the flanging mold inner cavity, and the lower end of the bushing can be accurately placed in the positioning groove, avoiding deflection and causing deformation at the bottom of the bushing. The bushing to be flanged is stable in positioning during the flanging stamping forming process, ensuring the flanging quality of the bushing; for bushing products of the same diameter with different lengths, only by replacing the top rod, the positioning of bushing products of different lengths and subsequent flanging processing can be realized, without the need to replace the mold as a whole. The same mold can realize the processing of multiple bushing products with different heights, reducing the mold cost and having strong applicability.

[0008] Third, the structure of the present invention is simple and the operation is convenient, improving the automation level of the bushing flanging processing, ensuring the quality of the bushing flanging, without the need to replace the mold as a whole, reducing the mold cost and improving the applicability of the equipment of the present invention.

[0009] Based on the above technical solutions, the present invention can further be improved as follows: Further, the flipping assembly further includes a lifting seat plate and a flipping power mechanism. The lifting seat plate is installed on the flipping machine base in a liftable manner. The flipping plate and the flipping power mechanism are movably installed on the lifting seat plate through an adjustment assembly. The output end of the flipping power mechanism is connected to the flipping plate.

[0010] The beneficial effects of adopting the above further technical solution are: Through the lifting of the lifting seat plate, the flipping plate can rise and approach the feeding assembly to receive the bushing, and can also descend and approach the mold to realize the blanking of the bushing; The flipping plate is driven to flip by the flipping power mechanism.

[0011] Further, the adjustment assembly includes a translation seat. The translation seat is movably installed on the lifting seat plate. The flipping plate is rotatably installed on the translation seat. A translation driving mechanism is connected to the end of the translation seat. An installation plate is provided on the lifting seat plate. The translation driving mechanism is installed on the installation plate. A locking buckle is provided on the installation plate.

[0012] The beneficial effects of adopting the above further technical solution are: By installing the flipping plate and its flipping power mechanism on the lifting seat plate through the adjustment assembly, the flipping plate can be translated on the lifting seat plate. The translation seat is driven to move on the lifting seat plate by the translation driving mechanism, thereby driving the flipping plate to move. The adjusted translation seat is locked by the locking buckle. Since the central axes of bushings of different sizes have different heights on the flipping plate, when the bushing is driven by the flipping plate to flip, the position of the flipping plate before flipping will affect the position of the central axis of the bushing after flipping. And each time the mold moves to the corresponding working station, the position of the mold will be positioned by the positioning mechanism, so the position of the central axis of the mold is fixed on the frame. When it is necessary to adapt the flanging processing of bushings of different sizes, if the position of the flipping plate is not adjusted, after the flipping plate flips, the position of the central axis of the bushing will shift, and the relative position between the central axis of the bushing and the central axis of the mold will change, affecting the entry of the bushing into the mold. By adjusting the position of the flipping plate on the lifting seat plate through the adjustment assembly, the position of the central axis of the bushing after flipping is adjusted, so that the central axis of the bushing can be aligned with the central axis of the mold, improving the accuracy during the process of feeding the bushing into the mold.

[0013] Further, the flipping power mechanism includes a flipping cylinder, a transmission rack and a transmission gear. The flipping cylinder is installed on the translation seat. The transmission rack is movably installed on the translation seat. The end of the piston rod of the flipping cylinder is connected to the transmission rack. The transmission gear is rotatably installed on the translation seat through a bearing. The transmission gear meshes with the transmission rack. The transmission gear is fixedly connected to the flipping plate.

[0014] The beneficial effects of adopting the above further technical solution are as follows: The telescopic movement of the piston rod of the turning cylinder drives the transmission rack to move on the lifting seat plate. The movement of the transmission rack can drive the transmission gear to rotate, thereby driving the turning plate to rotate, realizing the turning of the turning plate. Since the material receiving plate is arranged on the turning plate, when the bushing is placed on the material receiving plate, the bushing is horizontally placed. The pressing member moves downward to press the bushing. When the turning plate turns, it can drive the bushing horizontally placed on the material receiving plate to turn to a vertical state, facilitating the feeding of the bushing into the lower mold. During this process, the pressing member keeps pressing the bushing to prevent the bushing from falling prematurely.

[0015] Further, the pushing mechanism includes a pushing frame and a pushing power cylinder. The pushing power cylinder is fixedly installed on the frame. The pushing frame is movably installed on the frame. The piston rod of the pushing power cylinder is connected to the pushing frame. The material blocking mechanism is arranged on the pushing frame. The material blocking mechanism includes a material blocking member and a material blocking power cylinder. The material blocking power cylinder is fixedly installed on the pushing frame. The material blocking member is installed at the end of the piston rod of the material blocking power cylinder. A space for accommodating the bushing is provided between the material blocking member and the pushing frame. The material blocking member includes a material blocking top plate and a material blocking side plate. The piston rod of the material blocking power cylinder is connected to the material blocking top plate. The material blocking side plate is arranged at the end of the material blocking top plate. The pushing frame includes a moving frame body and a material blocking push plate. The piston rod of the pushing power cylinder is connected to the moving frame body. The material blocking push plate is arranged at the end of the moving frame body. A guide material support plate is provided at the bottom of the moving path of the material blocking push plate.

[0016] The beneficial effects of adopting the above further technical solution are as follows: The pushing power cylinder drives the pushing frame to move, thereby driving the material blocking mechanism to move and driving the bushing to move. The bushing is blocked by the material blocking member. A space for accommodating the bushing is provided between the material blocking member and the pushing frame. When the material blocking member moves under the drive of the pushing power cylinder and the pushing frame, it can drive the bushing to move. The end of the bushing is blocked and positioned by the material blocking top plate, and the side of the bushing is blocked by the material blocking side plate to prevent the bushing from deviating during movement. The bushing moves on the guide material support plate, and the material blocking side plate and the material blocking push plate block the side of the bushing to prevent the bushing from deviating during movement.

[0017] Furthermore, a rod head is provided at the upper end of the ejector rod, a pad hole is provided on the support pad, a limiting shoulder for limiting the rod head is provided in the pad hole, the diameter of the rod head is greater than the inner diameter of the limiting shoulder, and the rod end of the ejector rod passes through the pad hole and is connected to the base; the inner cavity of the flanging die includes a communicating frustum-shaped hole and a cylindrical hole, and the frustum-shaped hole and the cylindrical hole are sequentially arranged in the forming die base from top to bottom; the forming die base includes an upper die base section, a middle die base section and a lower die base section, the outer diameter of the lower die base section is smaller than the outer diameter of the middle die base section, and the outer diameter of the upper die base section is smaller than the outer diameter of the middle die base section.

[0018] The beneficial effects of adopting the above further scheme are as follows: the upper end of the support spring acts on the support pad, and a positioning groove for positioning the bottom end of the bushing is formed by the cooperation between the support pad and the ejector rod. The rod head acts on the limiting shoulder, which can limit the highest position of the upward movement of the support pad; the hole wall of the frustum-shaped hole is inclined to be the acting surface during forming, which is convenient for the flanging forming of the end of the bushing. The cylindrical hole can wrap and support the bushing to ensure the quality of the bushing during stamping and reduce or even avoid its deformation; the lower part of the forming die base, that is, the lower die base section, adopts a small-diameter section structure design, and a ring groove is formed between the lower die base section and the middle die base section, which can be engaged and matched with the rotating bayonet on the rotating plate of the subsequent die conveying component to drive the die to turnover and ensure the stability of the bushing rotation feeding; the outer diameter of the upper die base section is smaller than the outer diameter of the middle die base section, which is mainly used for weight reduction to prevent the die from tipping during rotation.

[0019] Furthermore, the ejector rod is connected to the base through a connecting mechanism. The connecting mechanism includes a rod pin hole and a connecting pin rod that can be inserted into the rod pin hole. The base is provided with a positioning hole for installing the ejector rod, and the ejector rod and the base are correspondingly provided with the rod pin holes for the connecting pin rod to pass through.

[0020] The beneficial effects of adopting the above further scheme are as follows: the ejector rod is connected to the base through the connecting mechanism. The lower end of the ejector rod is placed in the positioning hole, and the connecting pin rod is inserted into the rod pin hole on the base, and then inserted into the rod pin hole on the ejector rod until it passes through the rod pin hole on the other side of the base. The base and the ejector rod are connected by the connecting pin rod, which is convenient for installation. When facing bushing products of different lengths, the disassembly and replacement of the ejector rod are also very convenient. The same flanging die can realize the flanging processing of bushing products of multiple different heights.

[0021] Further, the mold conveying assembly includes a limiting ring, a rotating plate, and a rotating driving mechanism. The rotating plate is rotatably arranged on the frame, and the rotating driving mechanism drives the rotating plate to rotate. The limiting ring is arranged on the outer periphery of the rotating plate. A plurality of rotating bayonets are arranged on the rotating plate. Corresponding to the feeding device, the stamping device, and the discharging assembly respectively, limiting top blocks are arranged on the limiting ring. A positioning groove is arranged on one side of the limiting top block facing the rotating plate. A positioning mechanism is arranged in the middle of the rotating plate. The positioning mechanism includes a plurality of positioning driving cylinders, which are respectively arranged corresponding to the limiting top blocks. A positioning push block is arranged at the end of the piston rod of the positioning driving cylinder. A positioning groove is arranged on one side of the positioning push block facing the limiting ring.

[0022] The beneficial effects of adopting the above further scheme are as follows: The rotating driving mechanism drives the rotating plate to rotate on the frame. Rotating bayonets are arranged on the rotating plate. The rotating bayonets and the limiting ring arranged on the outer periphery of the rotating plate jointly form a space for placing the mold. And during the rotation of the rotating plate, the mold is driven to rotate through the rotating bayonets, so as to move the mold to different working positions. During the rotation process, the outer side of the mold is limited by the limiting ring to prevent the mold from flipping or flying off. Each time the mold moves to the corresponding working position, the piston rod of the positioning driving cylinder extends to push the mold towards the limiting top block. The positioning of the mold is realized through the limitation of the limiting top block, ensuring the accurate position of the mold at each working position, thereby ensuring the accuracy of feeding, stamping, and discharging. Positioning grooves are respectively arranged on the limiting top block and the positioning push block. The shape of the positioning groove is V-shaped or arc-shaped, which can realize automatic alignment and positioning, and is convenient to operate.

[0023] Further, the discharging assembly includes a discharging machine base and a discharging power cylinder arranged on the frame. A mold blocking top plate and a discharging guide plate are arranged on the discharging machine base. The height of the mold blocking top plate is higher than the height of the mold. A discharging top pushing hole is arranged on the mold blocking top plate. The discharging guide plate is arranged above the mold blocking top plate. A discharging slot opening is arranged at the bottom of the discharging machine base. The discharging slot opening penetrates through the frame. The discharging guide plate is inclined. The discharging power cylinder is arranged corresponding to the mold blocking top plate of the discharging machine base. The piston rod of the discharging power cylinder extends or retracts in the direction towards or away from the discharging top pushing hole.

[0024] The beneficial effects of adopting the above further solution are as follows: The flanged bushing after flanging is in the mold and moves to the discharging component station driven by the rotating plate. At this time, the mold is located below the die-block top plate. As the piston rod of the discharging power cylinder extends, the piston rod of the discharging power cylinder acts on the support seat of the mold to jack up the support seat. The die-block top plate limits the mold. The ejector rod of the support seat moves upward to drive the flanged bushing upward. The flanged bushing can disengage from the forming die base and pass through the discharging push hole. Under the action of inertia, after the flanged bushing disengages from the forming die base, it moves upward and touches the discharging guide plate. Under the guiding action of the discharging guide plate, the flanged bushing drops towards the discharging notch and falls into the aggregate box below the discharging notch, realizing the discharging of the flanged bushing. As the support seat jacks up and moves upward, the support pad is compressed by the forming die base and compresses the support spring, which will not prevent the discharging of the flanged bushing. After the discharging of the flanged bushing is completed, the discharging power cylinder resets, and the support seat resets under the action of the support spring, forming a positioning groove between the ejector rod and the support pad. The mold moves to the feeding station driven by the rotating plate, waiting for the next bushing to be flanged, realizing the batch flanging processing of bushing products.

[0025] Further, the stamping device includes a stamping machine base, a stamping power cylinder and a stamping head. The stamping machine base is arranged on the frame. The stamping power cylinder is installed on the stamping machine base. The end of the piston rod of the stamping power cylinder is connected to the stamping head. The end of the stamping head is conical. A calibration component is also arranged on the stamping machine base. The feeding device further includes a vibrating feeding tray and a feeding guide groove. The discharging end of the vibrating feeding tray is connected to the feeding guide groove, and the other end of the feeding guide groove is connected to the material blocking mechanism.

[0026] The beneficial effects of adopting the above further solution are as follows: The bushing to be flanged is in the mold and moves to the stamping station driven by the rotating plate. At this time, the mold is located below the stamping head. The stamping power cylinder drives the stamping head to move downward to impact the edge of the end of the bushing. Since the tapered hole in the inner cavity of the flanging die has a certain inclination angle, it provides a working surface for the flanging and forming of the bushing. The bushing product can be stamped and formed by the downward stamping of the stamping head, realizing the flanging processing of the bushing. Since the end of the stamping head is conical, it can be adapted to the flanging processing of bushings with different diameters. The position of the stamping head is calibrated by the calibration component, which is convenient for adjusting the stamping distance. The automatic feeding of the bushing is realized through the vibrating feeding tray and the feeding guide groove. After feeding to the material blocking mechanism, the material blocking mechanism blocks the bushing to be flanged, which is convenient for calibrating the feeding position of the bushing to be flanged.

[0031] Specifically, the adjustment component includes a translation base 401. The translation base 401 is movably mounted on the lifting seat plate 312 through a guide rail 402 and a slider.

A gap is left between the material blocking side plate 204 and the material blocking and pushing plate 2012, that is, a space for accommodating the bushing 4 is formed among the material blocking side plate 204, the material blocking top plate 203 and the material blocking and pushing plate 2012. A material guiding support plate is provided at the bottom of the moving path of the material blocking and pushing plate 2012. The side of the material guiding support plate facing the flipping assembly 300 is inclined downward. The height of the material receiving plate 302 is lower than that of the material guiding support plate. In this embodiment, both the material blocking member and the material blocking and pushing plate 2012 are quick-change mechanisms. The length of the material blocking and pushing plate 2012 is adapted to the length of the bushing 4. Acting together with the material blocking member, the positioning in the length direction of the bushing 4 is realized through the material blocking and pushing plate 2012.

[0039] The mold 100 includes a forming die base 101 and a support assembly 102 provided in the forming die base 101. A flanging die inner cavity 1011 for forming the bushing 4 and a support receiving cavity 1012 for accommodating the support assembly 102 are provided in the forming die base 101. The flanging die inner cavity 1011 is provided above the support receiving cavity 1012. The support assembly 102 includes a support seat, a support pad 1024 and a support spring 1023. The support seat includes a base 1021 and a ejector rod 1022 provided on the base 1021. The support pad 1024 is slidably sleeved on the ejector rod 1022. The support spring 1023 is sleeved on the ejector rod 1022 between the base 1021 and the support pad 1024. A positioning groove 1025 for positioning the lower end of the slotted bushing 4 is formed by the cooperation between the support pad 1024 and the ejector rod 1022.

[0040] A rod head 1022-1 is provided at the upper end of the ejector rod 1022. A pad hole 1024-1 is provided on the support pad 1024. A limiting shoulder for limiting the rod head 1022-1 is provided in the pad hole 1024-1. The diameter of the rod head 1022-1 is larger than the inner diameter of the limiting shoulder. The rod end of the ejector rod 1022 passes through the pad hole 1024-1 and is connected to the base 1021. The upper end of the support spring 1023 acts on the support pad 1024. A positioning groove 1025 for positioning the bottom end of the bushing 4 is formed by the cooperation between the support pad 1024 and the ejector rod 1022. The rod head 1022-1 acts on the limiting shoulder, which can limit the highest position of the upward movement of the support pad 1024.

[0041] The inner cavity 1011 of the flanging die includes a frustum-shaped hole 1011-1 and a cylindrical hole 1011-2 that are connected. The frustum-shaped hole 1011-1 and the cylindrical hole 1011-2 are arranged in the forming die base 101 from top to bottom in sequence. The hole wall of the frustum-shaped hole 1011-1 is inclined to be the acting surface during forming, which is convenient for the flanging forming of the end of the bushing 4. The cylindrical hole 1011-2 can wrap and support the bushing 4 to ensure the quality of the bushing 4 during stamping and reduce or even avoid its deformation.

[0042] The forming die base 101 includes an upper die base section 1015, a middle die base section, and a lower die base section 1014. The outer diameter of the lower die base section 1014 is smaller than that of the middle die base section, and the outer diameter of the upper die base section 1015 is smaller than that of the middle die base section. The lower part of the forming die base 101, that is, the lower die base section 1014, adopts a small-diameter section structure design. A ring groove is formed between the lower die base section 1014 and the middle die base section, which can be engaged and matched with the rotating bayonet 5021 on the subsequent rotating plate 502 to drive the turnover of the flanging die 100 and ensure the stability of the circumferential rotation and feeding of the bushing 4, making the die 100 more stable and reliable during the rotating feeding process. The small-diameter section structure design of the upper die base section 1015 is mainly used for weight reduction to prevent the die 100 from tipping during rotation.

[0043] The support pad 1024 includes an upper pad body and a lower pad body 1024-2. The outer diameter of the upper pad body is larger than that of the lower pad body 1024-2. A seat groove 1021-1 is provided on the base 1021. When the lower pad body 1024-2 moves upward on the base 1021 and the ejector rod 1022 ejects the bushing 4, it can be placed in the seat groove 1021-1. The depth of the seat groove 1021-1 is greater than the height of the lower pad body 1024-2. During the process of ejecting the bushing 4, the base 1021 and the ejector rod 1022 move upward, the base 1021 compresses the support spring 1023, the lower pad body 1024-2 can be completely placed in the seat groove 1021-1, and the upper surface of the base 1021 can act on the bottom surface of the upper pad body without problems such as inclination, ensuring that the ejector rod 1022 smoothly ejects the bushing 4.

[0044] The ejector rod 1022 is connected to the base 1021 through a connecting mechanism. The connecting mechanism includes a rod pin hole and a connecting pin rod 1026 that can be inserted into the rod pin hole. The base 1021 is provided with a positioning hole for installing the ejector rod 1022. The ejector rod 1022 and the base 1021 are correspondingly provided with the rod pin holes through which the connecting pin rod 1026 passes; the lower end of the ejector rod 1022 is placed in the positioning hole, and the connecting pin rod 1026 is inserted from the rod pin hole on the base 1021, and then inserted into the rod pin hole on the ejector rod 1022 until it passes through the rod pin hole on the other side of the base 1021. The base 1021 and the ejector rod 1022 are connected through the connecting pin rod 1026, which is convenient for installation. When facing bushing 4 products of different lengths, the disassembly and replacement of the ejector rod 1022 are also very convenient. The same flanging die 100 can realize the flanging processing of bushing 4 products of various different heights.

[0045] The ejector rod 1022 and the base 1021 are in interference fit. The outer diameter of the lower end of the ejector rod 1022 is larger than the positioning hole on the base 1021. The ejector rod is press-fitted onto the base, and the ejector rod and the base are in transitional fit to ensure the connection stability between the two, and it is also convenient for the disassembly and replacement of ejector rods of different heights in the follow-up.

[0046] The die 100 further includes an anti-disengagement mechanism. The base 1021 is arranged on the forming die base 101 through the anti-disengagement mechanism. The support assembly 102 is installed in the forming die base 101. Without the anti-disengagement mechanism, when picking up the die 100, the support assembly 102 will be disengaged from the forming die base 101, which is not convenient for the overall picking up, transferring and storing of the die 100. The anti-disengagement mechanism can associate the support assembly 102 with the forming die base 101 without affecting the use function of the die 100. The support assembly 102 can move relative to the forming die base 101, but will not be disengaged from the forming die base 101, which is convenient for the overall picking up, transferring and storing of the die 100.

[0047] The anti-disengagement mechanism includes an anti-disengagement keyway 1013 and an anti-disengagement rod 103 that can move up and down outside the anti-disengagement keyway 1013. The anti-disengagement keyway 1013 is arranged on the forming die base 101, and the inner end of the anti-disengagement rod 103 is connected to the base 1021. The anti-disengagement keyway 1013 is a long strip through hole and is axially arranged on the forming die base 101. The inner end of the anti-disengagement rod 103 is inserted into the anti-disengagement keyway 1013 and is connected to the base 1021 located in the forming die base 101. The outside of the anti-disengagement rod 103 can move up and down in the anti-disengagement keyway 1013. By controlling the length of the anti-disengagement keyway 1013, the ejection height can be controlled to prevent excessive ejection and interfere with the structure on the discharge assembly 700. It not only meets the requirement that the support assembly 102 will not be disengaged from the forming die base 101, but also controls the up and down movement distance of the base 1021 and the ejector rod 1022 in the forming die base 101.

[0048] One end of the anti - detachment rod 103 is threadedly connected to the base 1021, and the other end is movable within the anti - detachment keyway 1013. After the support assembly 102 is installed in the support receiving cavity 1012 of the forming die base 101, the inner end of the anti - detachment rod 103 can be inserted from the anti - detachment keyway 1013 on the side and threadedly connected to the base 1021. The outer end can move up and down within the anti - detachment keyway 1013, preventing the support assembly 102 from detaching from the forming die base 101.

[0049] The mold conveying assembly 500 includes a limiting ring 501, a rotating plate 502, and a rotation driving mechanism. The rotating plate 502 is rotatably arranged on the frame 900, and the rotation driving mechanism drives the rotating plate 502 to rotate. A transition station is also provided on the frame 900. The transition station can be arranged between any two adjacent stations among the feeding device, the stamping device 600, and the discharging assembly 700. In this embodiment, the transition station is arranged between the feeding device and the stamping device 600, so that a 90° angle is formed between adjacent stations of the feeding device, the transition station, the stamping device 600, and the discharging assembly 700. Each time the rotation driving mechanism only needs to drive the rotating plate 502 to rotate 90° to move the mold 100 to the adjacent next station, which is convenient for the conveying of the mold 100. The limiting ring 501 is arranged on the outer periphery of the rotating plate 502. A plurality of rotating bayonets 5021 are provided on the rotating plate 502. Corresponding to the feeding device, the transition station, the stamping device 600, and the discharging assembly 700 respectively, limiting top blocks 5011 are provided on the limiting ring 501. For the rationality of the spatial position design of each component of the present invention, in this embodiment, the positions where the flipping assembly 300, the transition station, the stamping device 600, and the discharging assembly 700 are arranged form a 90° angle with the connecting lines of the centers of the rotating plate 502 respectively. A positioning groove is provided on the side of the limiting top block 5011 facing the rotating plate 502. A positioning mechanism is provided in the middle of the rotating plate 502. The positioning mechanism includes a plurality of positioning driving cylinders 503. The positioning driving cylinders 503 are installed on the rotating plate 502 and are respectively arranged corresponding to the feeding device, the transition station, the stamping device 600, and the discharging assembly 700. When the piston rods of the positioning driving cylinders 503 extend, they can push the molds 100 on the feeding device, the transition station, the stamping device 600, and the discharging assembly 700 to move towards the limiting top block 5011. A positioning push block 5031 is provided at the end of the piston rod of the positioning driving cylinder 503. A positioning groove is provided on the side of the positioning push block 5031 facing the limiting ring 501. The shapes of the positioning grooves on the positioning push block 5031 and the limiting top block 5011 are V-shaped or arc-shaped. In this embodiment, the rotation driving mechanism includes a rotation motor 504. The rotation motor 504 is installed on the frame 900, and the output end of the rotation motor 504 is in transmission connection with the rotating plate 502. To reduce the weight, a hollow structure is provided on the rotating plate 502.

[0050] The discharging assembly 700 includes a discharging base 701 and a discharging power cylinder 702 provided on the frame 900. The discharging base 701 includes a discharging base housing 706. Inside the discharging base housing 706, there are provided a die-block top plate 703 and a discharging guide plate 704. The die-block top plate 703 is provided at the bottom of the discharging base housing 706 and the height of the die-block top plate 703 is higher than the height of the die 100. The die-block top plate 703 is provided with a discharging push hole 7031, and the diameter of the discharging push hole 7031 is larger than the diameter of the frustum-shaped hole 1011-1 of the die 100. The discharging guide plate 704 is provided above the die-block top plate 703. The bottom of the discharging base housing 706 is further provided with a discharging notch 705. The discharging notch 705 is adjacent to the die-block top plate 703. The discharging notch 705 penetrates through the frame 900. The discharging notch 705 is connected to a discharging channel. Below the discharging channel, there is an aggregate bin (not shown in the figure). The discharging guide plate 704 is inclined. The discharging guide plate 704 is inclined upward toward the discharging notch 705, so as to provide a guiding effect for the discharging of the bushing 4, and guide the bushing 4 to slide out from the discharging notch 705 and fall into the aggregate bin. The discharging power cylinder 702 is arranged corresponding to the die-block top plate 703 of the discharging base 701. The piston rod of the discharging power cylinder 702 expands and contracts in the direction toward or away from the discharging push hole 7031. The flanged bushing 4 after flanging is in the die 100 and is moved to the station of the discharging assembly 700 driven by the rotating plate 502. At this time, the die 100 is located below the die-block top plate 703. By the extension of the piston rod of the discharging power cylinder 702, the piston rod of the discharging power cylinder 702 acts on the support seat of the die 100 to jack up the support seat. The die-block top plate 703 can limit the die 100. The support seat drives the ejector rod 1022 to move upward. The ejector rod 1022 acts on the flanged bushing 4. The flanged bushing 4 moves upward. The flanged bushing 4 can be separated from the forming die base 101 and pass through the discharging push hole 7031. Under the action of inertia, after the flanged bushing 4 is separated from the forming die base 101, it continues to move upward and touches the discharging guide plate 704. Under the guiding action of the discharging guide plate 704, the flanged bushing 4 falls toward the discharging notch 705 into the aggregate bin below the discharging notch 705, realizing the discharging of the flanged bushing 4. As the support seat is jacked up and moved upward, the support pad 1024 is compressed by the forming die base 101 to act on the support spring 1023, which will not prevent the discharging of the flanged bushing 4. After the discharging of the flanged bushing 4 is completed, the discharging power cylinder 702 resets. The support seat resets under the action of the support spring 1023. A positioning groove 1025 is formed between the ejector rod 1022 and the support pad 1024. The die 100 is moved to the feeding station driven by the rotating plate 502, waiting for the next bushing 4 to be flanged, realizing the batch flanging processing of the bushing 4 products.

[0051] The stamping device 600 includes a stamping base 601, a stamping power cylinder 602 and a stamping head 603. The stamping base 601 is arranged on the frame 900. The stamping power cylinder 602 is installed on the stamping base 601. The end of the piston rod of the stamping power cylinder 602 is connected to the stamping head 603. The end of the stamping head 603 is conical. A calibration assembly 604 is also provided on the stamping base 601. The bushing 4 to be flanged is within the mold 100 and is moved to the stamping station driven by the rotating plate 502. At this time, the mold 100 is located below the stamping head 603. The stamping power cylinder 602 drives the stamping head 603 to move downward to impact the edge of the end of the bushing 4. Since the tapered hole 1011-1 in the inner cavity 1011 of the flanging die has a certain inclination angle, it provides a working surface for the flanging of the bushing 4. The bushing 4 can be formed by stamping through the downward stamping of the stamping head 603, realizing the flanging process of the slotted bushing 4. Since the end of the stamping head 603 is conical, it can be adapted to the flanging of bushings 4 with different diameters. The position of the stamping head 603 is calibrated by the calibration assembly 604, facilitating the adjustment of the stamping distance.

[0052] The feeding device further includes a vibrating feeding tray 801 and a feeding guide groove 802. The discharging end of the vibrating feeding tray 801 is connected to the feeding guide groove 802, and the other end of the feeding guide groove 802 is connected to the material blocking mechanism.

[0053] The working process of the slotted bushing flanging equipment of the present invention is as follows: I. When in use, first install the mold 100. Specifically, install the support assembly 102 in the support accommodation cavity 1012 at the bottom of the forming die base 101. Install the anti-disengagement rod 103 from the anti-disengagement key groove 1013 on the side of the forming die base 101. The rod end of the anti-disengagement rod 103 is threadedly connected to the base 1021. The support assembly 102 is associated with the forming die base 101 through the anti-disengagement mechanism. The center of the forming die base 101 is coaxial with the support assembly 102. The anti-disengagement rod 103 can move up and down within the movable range of the anti-disengagement key groove 1013. The base 1021 and the ejector rod 1022 can move up and down in the forming die base 101, so as to realize positioning and wrapping the bushing 4 to be flanged or ejecting the flanged bushing 4 product. Place the installed mold 100 on the space formed by the rotating bayonet 5021 of the rotating plate 502 and the limit ring 501.

[0054] II. The bushing 4 is vibrated and conveyed to the feeding guide groove 802 by the vibrating feeding tray 801, and is conveyed to the pushing component 200 through the feeding guide groove 802. Before that, the piston rod of the material blocking power cylinder 205 extends to drive the material blocking top plate 203 and the material blocking side plate 204 to move into place. At this time, a space for accommodating the bushing 4 is formed among the material blocking side plate 204, the material blocking top plate 203 and the material blocking push plate 2012. The vibrating feeding tray 801 conveys the bushing 4 onto the guide supporting plate and into the space for accommodating the bushing 4 formed among the material blocking side plate 204, the material blocking top plate 203 and the material blocking push plate 2012.

[0055] III. The piston rod of the pushing power cylinder 202 extends, driving the pushing frame 201 and the material blocking component to move towards the flipping component 300. Before that, the lifting power cylinder 313 drives the lifting seat plate 312 to rise into place, so that the height of the material receiving plate 302 is adapted to the height of the guide supporting plate. The bushing 4 is pushed by the pushing frame 201, moves on the guide supporting plate, and rolls from the guide supporting plate onto the material receiving plate 302. The material blocking side plate 204 and the material blocking push plate 2012 provide blocking on both sides of the bushing 4 to prevent the bushing 4 from shifting.

[0056] IV. After the bushing 4 moves onto the material receiving plate 302, the material blocking power cylinder 205 retracts, so that the material blocking side plate 204 does not contact the bushing 4 and is not on the same vertical line. The pushing power cylinder 202 retracts to drive the material blocking push plate 2012, the material blocking top plate 203 and the material blocking side plate 204 to reset, so that the bushing 4 is independently located on the material receiving plate 302, and the pushing component 200 waits for the next bushing 4 to be blocked and pushed.

[0057] V. After the bushing 4 moves onto the material receiving plate 302, the pressing power cylinder 309 drives the pressing piece to move downward, and the pressing plate 304 presses the bushing 4. At this time, the flipping cylinder 305 drives the transmission rack 306 to move, and the movement of the transmission rack 306 drives the transmission gear 307 to rotate. The flipping plate 308 flips along with the transmission gear 307, thereby driving the bushing 4 on the material receiving plate 302 to flip. Before that, the rotating motor 504 drives the rotating plate 502 to rotate, driving the mold 100 located on the rotating bayonet 5021 to rotate to the station of the flipping component 300 and be located below the flipping plate 308. The piston rod of the positioning driving cylinder 503 extends to push the mold 100 against the corresponding limit top block 5011 at the station of the flipping component 300 to realize the positioning of the mold 100 at the flipping station; the flipping cylinder 305 drives the transmission gear 307 to rotate by an angle of 90°, thereby driving the flipping plate 308 to flip by 90°, so that the bushing 4 on the flipping plate 308 flips from the horizontal placement to the vertical placement, ensuring that the bushing 4 can be aligned with the flanging die inner cavity 1011 of the mold 100.

[0058] 6. After the bushing 4 is flipped into place, the lifting power cylinder 313 drives the lifting seat plate 312 to descend, bringing the bushing 4 closer to the mold 100. After the lifting seat plate 312 descends in place, the piston rod of the blanking power cylinder 311 drives the blanking plate 303 to move towards the bushing 4, pushing the bushing 4 into the flanging die inner cavity 1011 of the mold 100, and the feeding of the bushing 4 is completed. After the feeding of the bushing 4 is completed, the flipping cylinder 305 drives the transmission rack 306 to move in the reverse direction. The movement of the transmission rack 306 drives the transmission gear 307 to rotate, and the flipping plate 308 flips and resets with the transmission gear 307. The lifting power cylinder 313 drives the lifting seat plate 312 to rise, and continues to complete the feeding operation of the next bushing 4.

[0059] 7. The rotating motor 504 drives the rotating plate 502 to rotate. The rotating plate 502 drives the mold 100 with the bushing 4 to be flanged located in its flanging die inner cavity 1011 to rotate to the stamping device 600 station. The piston rod of the positioning drive cylinder 503 extends to push the mold 100 against the corresponding limit top block 5011 at the stamping device 600 station, realizing the positioning of the mold 100 at the stamping station. The piston rod of the stamping power cylinder 602 extends, driving the stamping head 603 to stamp downward. The tapered hole 1011-1 in the flanging die inner cavity 1011 has a certain inclination angle, which is the acting surface when the bushing 4 is flanged and formed. Through the up-and-down stamping method, the bushing 4 product can be stamped and formed, realizing the flanging processing of the bushing 4. After the processing is completed, the piston rod of the stamping power cylinder 602 retracts to drive the stamping head 603 to reset. The rotating motor 504 drives the rotating plate 502 to rotate, driving the mold 100 to rotate to the discharging assembly 700.

[0060] 8. The rotating motor 504 drives the rotating plate 502 to rotate. The rotating plate 502 drives the mold 100 and the flanged bushing 4 located in its flanging die inner cavity 1011 to rotate to the discharging assembly 700 station. The piston rod of the positioning drive cylinder 503 extends to push the mold 100 against the corresponding limit top block 5011 at the discharging assembly 700 station, realizing the positioning of the mold 100 at the discharging station. At this time, the mold 100 is located below the mold blocking top plate 703. The piston rod of the discharging power cylinder 702 extends, and the piston rod of the discharging power cylinder 702 acts on the support seat of the mold 100, thereby jacking up the support seat. The mold blocking top plate 703 limits the mold 100. The ejector rod 1022 of the support seat moves upward to drive the flanged bushing 4 to move upward. The flanged bushing 4 can be separated from the forming die base 101 and pass through the discharging push hole 7031. Under the action of inertia, after the flanged bushing 4 is separated from the forming die base 101, it continues to move upward and touches the discharging guide plate 704. Under the guiding action of the discharging guide plate 704, the flanged bushing 4 falls towards the discharging slot 705 into the aggregate box below the discharging slot 705, realizing the discharging of the flanged bushing 4.

[0061] IX. As the support base is jacked up and moves upward, the support pad 1024 will compress the support spring 1023 under the action of the forming die base 101, which will not prevent the discharging of the flanging bushing 4. After the discharging of the flanging bushing 4 is completed, the discharging power cylinder 702 resets, and the support base resets under the action of the support spring 1023, forming a positioning groove 1025 between the ejector rod 1022 and the support pad 1024. The die 100 rotates back to the loading station driven by the rotating plate 502, waiting for the next bushing 4 to be flanged, so as to realize the batch flanging processing of the bushing 4 product.

[0062] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
