Description

Technical Field

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

[0002] Slotted bushings are commonly used components for fatigue strengthening of mounting holes on aircraft. They mainly use cold extrusion strengthening technology and have the characteristics of large interference, strong operability, and obvious extrusion effect. They can significantly improve the fatigue life of structural parts made of various materials. With the advancement of localization of slotted bushings, the application of domestic slotted bushings has become more and more extensive, and has achieved good results.

[0003] One end of the slotted bushing features a flanging structure for easy installation and removal. Flanging is a key process for slotted bushings. Using a die and stamping process, the hole end or outer edge of the cylindrical slotted bushing semi-finished product is turned into a straight or beveled edge facing outward. This flanging process ensures excellent rigidity for the component. Currently, domestic flanging of slotted bushings primarily uses a punch press with a custom die for stamping. Due to a lack of automated equipment, the existing technology still relies on manual processing, resulting in low efficiency. In addition, most of the existing flanging molds are fixed structures, that is, a mold cavity adapted to the slit bushing product is set in the flanging mold, the slit bushing to be flanging is placed in the mold cavity, and the flanging of the slit bushing end is achieved by stamping or pressing. This flanging mold needs to completely match the specifications of the slit bushing to be processed, and the outer circle size and height size of the slit bushing need to be considered. Slit bushings with the same outer circle size will have various height sizes, which cannot be applied to slit bushings with different height sizes. Slit bushings with different heights need to replace the corresponding flanging mold as a whole, which is not very applicable and is 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] Aiming at the defects of the prior art, the present invention provides a slotted bushing flanging device.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A slotted bushing flanging device comprises a frame, a feeding device, a mold, a mold conveying assembly, a punching 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 on the feeding device, the punching device, and the discharging assembly in sequence;

[0007] The feeding device includes a pushing assembly and a flip assembly; the pushing assembly includes a blocking mechanism and a pushing mechanism, the blocking mechanism is used to block the bushing, and the pushing mechanism is used to push the bushing blocked by the blocking mechanism to the flip assembly; the flip assembly includes a flip machine base, a flip plate is rotatably provided on the flip machine base, a receiving plate, a pressing mechanism and a blanking mechanism are provided on the flip plate, the receiving plate is used to support the bushing, the pressing mechanism includes a pressing piece, the pressing piece is movably mounted on the flip plate, the pressing piece is used to press the bushing supported on the receiving plate, the blanking mechanism includes a blanking plate, the blanking plate is movably mounted on the flip plate, and the blanking plate is used to push the bushing to be discharged into the mold after the flip plate is flipped;

[0008] The mold includes a forming mold base and a support assembly arranged in the forming mold base, the forming mold base is provided with a flanging mold inner cavity for bushing molding and a support accommodating cavity for accommodating the support assembly, and the flanging mold inner cavity is arranged above the support accommodating cavity; the support assembly includes a support seat, a support pad and a support spring, the support seat includes a base and a push rod arranged on the base, the support pad is slidably mounted on the push rod, the support spring is mounted on the push rod between the base and the support pad, and the support pad and the push rod cooperate to form a positioning groove for positioning the lower end of the bushing.

[0009] The beneficial effects of the present invention are:

[0010] 1. The loading device of the present invention blocks and feeds the bushing through the pushing assembly, feeds the bushing to the flipping assembly, fixes the bushing through the receiving plate and the pressing mechanism, flips the bushing into place through the flipping plate, and pushes the bushing into the mold through the blanking plate, thereby realizing automatic loading of the bushing without manual loading and improving processing efficiency.

[0011] 2. The mold of the present invention acts on the support pad through the upper end of the support spring, and acts on the base through the lower end. The push rod and the support pad cooperate to form a positioning groove for positioning the slit bushing, ensuring that the bushing to be flanging is placed into the inner cavity of the flanging mold. The lower end of the bushing can be accurately placed in the positioning groove to avoid deviation and deformation of the bottom of the bushing. The bushing to be flanging is stably positioned during the flanging stamping process, ensuring the flanging quality of the bushing; bushing products with the same diameter have specifications of different lengths. Only the push rod needs to be replaced to achieve the positioning and subsequent flanging processing of bushing products of different lengths. There is no need to replace the mold as a whole. The same mold can realize the processing of bushing products of various heights, reducing the mold cost and having strong applicability.

[0012] 3. The present invention has a simple structure and is easy to operate. It improves the automation level of the bushing flanging process and ensures the quality of the bushing flanging. It does not require the overall replacement of the mold, reduces the mold cost, and improves the applicability of the equipment of the present invention.

[0013] On the basis of the above technical solution, the present invention can also make the following improvements:

[0014] Furthermore, the flip assembly also includes a lifting seat plate and a flip power mechanism. The lifting seat plate can be lifted and lowered on the flip machine base. The flip plate and the flip power mechanism are movably mounted on the lifting seat plate through an adjustment assembly. The output end of the flip power mechanism is connected to the flip plate.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are: by lifting the lifting seat plate, the flip plate can rise and approach the pusher assembly to receive the bushing, and can also fall and approach the mold to realize the unloading of the bushing; the flipping of the flip plate is driven by the flipping power mechanism.

[0016] Furthermore, the adjustment assembly includes a translation seat, which is movably mounted on the lifting seat plate, and the flip plate is rotatably mounted on the translation seat. The end of the translation seat is connected to a translation drive mechanism, and the lifting seat plate is provided with a mounting plate, and the translation drive mechanism is mounted on the mounting plate, and a locking buckle is provided on the mounting plate.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is: the flip plate and its flip power mechanism are installed on the lifting seat plate through the adjustment component, so that the flip plate can be translated on the lifting seat plate, and the translation seat is driven to move on the lifting seat plate by the translation drive mechanism, thereby driving the flip plate to move, and the adjusted translation seat is locked by the locking buckle. Since the center axes of bushings of different sizes have different heights on the flip plate, when the bushing is flipped by the flip plate, the position of the flip plate before flipping will affect the position of the center axis of the bushing after the flip plate is flipped. Each time the mold moves to the corresponding workstation, the position of the mold will be positioned by the positioning mechanism. Therefore, the position of the center axis of the mold is fixed on the frame. When it is necessary to adapt to the flanging processing of bushings of different sizes, if the position of the flip plate is not adjusted, the position of the center axis of the bushing will be offset after the flip plate is flipped, and the relative position of the center axis of the bushing and the center axis of the mold will change, affecting the entry of the bushing into the mold. By adjusting the position of the flip plate on the lifting seat plate through the adjustment component, the position of the center axis of the bushing after flipping is adjusted, thereby ensuring that the center axis of the bushing is aligned with the center axis of the mold, thereby improving the accuracy of the bushing in the process of sending the bushing into the mold.

[0018] Furthermore, the flipping power mechanism includes a flip cylinder, a transmission rack and a transmission gear. The flip cylinder is installed on the translation seat, and the transmission rack is movably installed on the translation seat. The piston rod end of the flip cylinder is connected to the transmission rack, and the transmission gear is rotatably installed on the translation seat through a bearing. The transmission gear is engaged with the transmission rack, and the transmission gear is fixedly connected to the flip plate.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is: the transmission rack is driven to move on the lifting seat plate through the extension and contraction of the piston rod of the flip cylinder, and the movement of the transmission rack can drive the transmission gear to rotate, thereby driving the flip plate to rotate, and realizing the flipping of the flip plate; since the receiving plate is arranged on the flip plate, when the bushing is placed on the receiving plate, the bushing is placed horizontally, and the pressing piece moves downward to press the bushing. When the flip plate is flipped, it can drive the horizontally placed bushing on the receiving plate to flip to a vertical state, which is convenient for unloading the bushing into the mold below. In this process, the bushing is kept pressed by the pressing piece to prevent the bushing from falling off prematurely.

[0020] The lifting mechanism is anode and cathode in the furnace, and the cathode in cathode in the furnace is cathode in the furnace.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are: the pushing power cylinder drives the pushing rack to move, thereby driving the blocking mechanism to move and driving the bushing to move; the bushing is blocked by the blocking piece, and a space for accommodating the bushing is provided between the blocking piece and the pushing rack. When the blocking piece moves under the drive of the pushing power cylinder and the pushing rack, it can drive the bushing to move; the end of the bushing is blocked and positioned by the blocking top plate, and the side of the bushing is blocked by the blocking side plate to prevent the bushing from shifting during the movement. The bushing moves on the guide support plate, and the blocking side plate and the blocking push plate block the side of the bushing to prevent the bushing from shifting during the movement.

[0022] Furthermore, a rod head is provided at the upper end of the push rod, a pad hole is provided on the support pad, a limiting shoulder is provided in the pad hole for limiting the rod head, the diameter of the rod head is larger than the inner diameter of the limiting shoulder, and the rod end of the push rod is connected to the base through the pad hole; the inner cavity of the flanging mold includes connected frustum holes and cylindrical holes, and the frustum holes and cylindrical holes are arranged in sequence from top to bottom in the forming mold base; the forming mold base includes an upper section, a middle section and a lower section of the mold base, the outer diameter of the lower section of the mold base is smaller than the outer diameter of the middle section of the mold base, and the outer diameter of the upper section of the mold base is smaller than the outer diameter of the middle section of the mold base.

[0023] The beneficial effects of adopting the above-mentioned further scheme are as follows: the upper end of the support spring acts on the support pad, and the support pad and the push rod cooperate to form a positioning groove for positioning the bottom end of the bushing, and the rod head acts on the limit shoulder, which can limit the highest position of the support pad to move upward; the hole wall of the frustum hole is inclined as the acting surface during forming, which is convenient for flanging the end of the bushing, and the cylindrical hole can wrap and support the bushing, ensuring the quality of the bushing during stamping, reducing or even avoiding its deformation; the lower part of the forming die base, that is, the lower section of the die base, adopts a small-diameter section structure design, and an annular groove is formed between the lower section of the die base and the middle section of the die base, which can be engaged with the rotating bayonet on the rotating plate of the subsequent mold conveying assembly to drive the mold to rotate and ensure the stability of the bushing rotation feeding; the outer diameter of the upper section of the die base is smaller than the outer diameter of the middle section of the die base, which is mainly used to reduce weight and prevent the mold from tipping over during rotation.

[0024] Furthermore, the top rod is connected to the base through a connecting mechanism, and the connecting mechanism includes a rod pin hole and a connecting pin that can be inserted into the rod pin hole. The base is provided with a positioning hole for installing the top rod, and the top rod and the base are correspondingly provided with the rod pin holes for the connecting pin to pass through.

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the push rod is connected to the base through a connecting mechanism, the lower end of the push rod is placed in the positioning hole, the connecting pin is inserted from the rod pin hole on the base, and then inserted into the rod pin hole on the push rod until it passes through the rod pin hole on the base on the other side. The base and the push rod are connected by the connecting pin, which is easy to install. When facing bushing products of different lengths, the disassembly and replacement of the push rod is also very convenient. The same flanging mold can realize flanging processing of bushing products of various heights.

[0026] Furthermore, the mold conveying assembly includes a limiting ring, a rotating plate and a rotating drive mechanism, the rotating plate is rotatably arranged on the frame, the rotating drive mechanism drives the rotating plate to rotate, the limiting ring is arranged on the outer periphery of the rotating plate, and the rotating plate is provided with a plurality of rotating bayonet holes, the limiting ring is respectively provided with limiting top blocks corresponding to the loading device, the stamping device and the discharging assembly, and the limiting top block is provided with a positioning groove on the side of the rotating plate; a positioning mechanism is provided in the middle of the rotating plate, and the positioning mechanism includes a plurality of positioning drive cylinders, the positioning drive cylinders are respectively provided corresponding to the limiting top blocks, and a positioning push block is provided at the end of the piston rod of the positioning drive cylinder, and the positioning push block is provided with a positioning groove on the side of the limiting ring.

[0027] The beneficial effect of adopting the above-mentioned further scheme is that the rotating plate is driven to rotate on the frame by a rotating drive mechanism, and a rotating bayonet is provided on the rotating plate. The rotating bayonet and the limiting ring provided on the outer periphery of the rotating plate jointly form a space for placing the mold, and the mold is driven to rotate by the rotating bayonet during the rotation of the rotating plate, thereby moving the mold to different workstations. During the rotation, the outer side of the mold is limited by the limiting ring to prevent the mold from flipping or flying away; each time the mold moves to the corresponding workstation, the piston rod of the positioning drive cylinder is extended to push the mold toward the limiting top block, and the positioning of the mold is achieved by the limitation of the limiting top block, ensuring the accurate position of the mold at each workstation, thereby ensuring the accuracy of loading, stamping and discharging; positioning grooves are respectively provided on the limiting top block and the positioning push block, and the shape of the positioning grooves is V-shaped or arc-shaped, which can realize automatic alignment and positioning, and is easy to operate.

[0028] Furthermore, the discharging assembly includes a discharging machine base and a discharging power cylinder arranged on the frame, the discharging machine base is provided with a mold blocking top plate and a discharging guide plate, the height of the mold blocking top plate is higher than the height of the mold, the mold blocking top plate is provided with a discharging push hole, the discharging guide plate is arranged above the mold blocking top plate, the bottom of the discharging machine base is provided with a discharging groove, the discharging groove passes through the frame, the discharging guide plate is arranged at an angle, the discharging power cylinder is arranged corresponding to the mold blocking top plate of the discharging machine base, and the piston rod of the discharging power cylinder is extended and retracted toward or away from the discharging push hole.

[0029] The beneficial effect of adopting the above-mentioned further scheme is that the bushing with completed flanging is in the mold and is moved to the discharge assembly station under the drive of the rotating plate. At this time, the mold is located below the mold blocking top plate, and the piston rod of the discharge power cylinder is extended. The piston rod of the discharge power cylinder acts on the support seat of the mold to push the support seat upward. The mold blocking top plate limits the mold, and the top rod of the support seat moves upward to drive the flanging bushing to move upward. The flanging bushing can be detached from the forming mold base and pass through the discharge push hole. Under the action of inertia, the flanging bushing detaches from the forming mold base and moves upward to touch the discharge guide Plate, under the guidance of the discharge guide plate, the flanged bushing falls toward the discharge slot and into the collecting box below the discharge slot, thereby realizing the discharge of the flanged bushing; and as the support seat is lifted up, the support pad will compress the support spring under the action of the forming die seat, which will not hinder the discharge of the flanged bushing. After the discharge of the flanged bushing is completed, the discharge power cylinder is reset, and the support seat is reset under the action of the support spring, a positioning groove is formed between the push rod and the support pad, and the mold is driven by the rotating plate to move to the loading station, waiting for the next bushing to be flanged, thereby realizing batch flanging processing of bushing products.

[0030] Furthermore, 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 piston rod end of the stamping power cylinder is connected to the stamping head, the end of the stamping head is conical, and a calibration component is also provided on the stamping machine base; the feeding device also includes a vibrating feeding tray and a feeding guide groove, the discharge 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.

[0031] The beneficial effect of adopting the above further scheme is that the bushing to be flanging is moved to the stamping station in the die and driven by the rotating plate. At this time, the die is located below the punch head, and the punch head is driven downward by the punch power cylinder to impact the edge of the bushing end. Since the cone hole in the flanging die cavity has a certain inclination angle, it provides an action surface for the flanging of the bushing. The bushing product can be stamped and formed by the downward punching method of the punch head to realize the flanging of the bushing. Since the end of the punch head is conical, it can adapt to the flanging of bushings of different diameters; the position of the punch head is calibrated by the calibration component to facilitate the adjustment of the stamping distance. The bushing is automatically loaded by the vibrating loading plate and the loading guide groove. After loading to the blocking mechanism, the bushing to be flanging is blocked by the blocking mechanism to facilitate the calibration of the loading position of the bushing to be flanging.

The material receiving plate 302 is used to support the bushing 4. In order to better support the bushing 4 and facilitate the bushing 4 to roll into place, the upper surface of the material receiving plate 302 is V-shaped. The pressing mechanism includes a pressing piece, which is movably mounted on the turning plate 308.

The blanking plate 303 is used to push the bushing 4 to be blanked into the mold 100 after the turning plate 308 is turned over.

[0064] The flip assembly 300 also includes a lifting seat plate 312 and a flip power mechanism. The lifting seat plate 312 is installed on the flip machine base 301 in a liftable manner. In order to adapt to bushings 4 of different sizes, the flip plate 308 and the flip power mechanism are movably installed on the lifting seat plate 312 through an adjustment component. The moving direction of the flip plate 308 on the lifting seat plate 312 is perpendicular to the lifting direction of the lifting seat plate 312. The output end of the flip power mechanism is connected to the flip plate 308.

[0065] Specifically, the adjustment assembly includes a translation seat 401, which is movably mounted on the lifting seat plate 312 through a guide rail 402 and a slider, and the flip plate 308 is rotatably mounted on the translation seat 401.

The transmission gear 307 is engaged with the transmission rack 306, and the transmission gear 307 is fixedly connected to the flip plate 308. The piston rod of the flip cylinder 305 is extended and retracted to drive the transmission rack 306 to move on the translation seat 401. Since the transmission rack 306 is engaged with the transmission gear 307, the movement of the transmission rack 306 can drive the transmission gear 307 to rotate, thereby driving the flip plate 308 to rotate, and realizing the flipping of the flip plate 308; since the material receiving plate 302 is arranged on the flip plate 308, when the pushing assembly 200 pushes the bushing 4 onto the material receiving plate 302, the bushing 4 is placed horizontally, and the pressing piece moves downward to press the bushing 4. When the flip plate 308 flips and drives the material receiving plate 302 to rotate, it drives the horizontally placed bushing 4 on the material receiving plate 302 to flip to a vertical position. During this process, the pressing piece maintains pressure on the bushing 4 to prevent the bushing 4 from falling off prematurely.

[0067] The pressing mechanism includes a pressing power cylinder 309, which is installed on the flip plate 308, and the end of the piston rod of the pressing power cylinder 309 is connected to the pressing piece; the pressing piece includes a connecting block 310 and a pressing plate 304, and the end of the piston rod of the pressing power cylinder 309 is provided with a connecting plate, the connecting block 310 is installed on the connecting plate, and the pressing plate 304 is installed on the connecting block 310, and a slot is provided in the middle of the pressing plate 304, and the blanking plate 303 corresponds to the slot setting of the pressing plate 304. Since the bushing 4 is placed horizontally on the receiving plate 302, when the pressing plate 304 presses the bushing 4, the cylindrical surface of the bushing 4 contacts the pressing plate 304. If a single-sided contact is adopted, it is easy for the bushing 4 to roll over. A groove is provided on the pressing plate 304, so that the contact surface between the pressing plate 304 and the bushing 4 is increased to two, so that the bushing 4 can be better pressed and the bushing 4 can be prevented from being offset or rolling. The groove provides a moving channel for the blanking plate 303.

[0068] The blanking mechanism includes a blanking power cylinder 311 , which is mounted on the flip plate 308 , and an end of a piston rod of the blanking power cylinder 311 is connected to the blanking plate 303 .

[0093] 6. After the bushing 4 is flipped into place, the lifting power cylinder 313 drives the lifting seat plate 312 to descend, so that the bushing 4 is close to the mold 100. After the lifting seat plate 312 descends into place, the piston rod of the blanking power cylinder 311 drives the blanking plate 303 to move toward the bushing 4, pushing the bushing 4 into the flanging mold cavity 1011 of the mold 100, and the loading of the bushing 4 is completed; after the loading of the bushing 4 is completed, the flipping cylinder 305 drives the transmission rack 306 to move in the opposite direction, and the movement of the transmission rack 306 drives the transmission gear 307 to rotate, and the flip plate 308 flips and resets with the transmission gear 307, and the lifting power cylinder 313 drives the lifting seat plate 312 to rise, and continues to complete the loading operation of the next bushing 4.
