Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an automatic feeding and unloading mechanism and method for stamping automotive wheel covers. Background Technology

[0002] Automotive wheel covers refer to the structures that protect the tires, including the arc-shaped wheel cover above the tire and the decorative wheel cover that is directly attached to the side of the tire. The decorative wheel cover is usually a metal product and can be processed by stamping, which involves placing it into a hot stamping die of a stamping press for extrusion molding.

[0003] Chinese Patent Publication No.: CN 220612078U, Publication Date: March 19, 2024. This application discloses a stamping device for automobile wheel covers, relating to the field of automotive processing technology. It includes a base plate, with columns fixedly connected to the upper surface of the base plate near the four corners. Mounting seats are fixedly connected to the upper surfaces of the columns. A second telescopic rod is fixedly installed on the upper surface of the base plate near the front side. A second support plate is fixedly connected to the drive shaft end of the second telescopic rod. Second guide rods are symmetrically fixedly connected to the upper surface of the base plate near the second telescopic rod. The shortcomings of this technical solution are: 1. Low single stamping depth; loading and unloading rely on manual operation, making high-efficiency continuous stamping difficult; 2. To reduce the risk of cracking and wrinkling, multiple stamping processes are performed, but the angle adjustment between stamping operations requires manual unloading and rotation, further reducing stamping efficiency.

[0004] In summary, existing stamping mechanisms suffer from low efficiency in loading and unloading operations, which affects continuous stamping operations. Summary of the Invention

[0005] In order to overcome the shortcomings of existing stamping mechanisms, such as low efficiency in feeding and unloading operations, which affect continuous stamping operations, an automatic feeding and unloading mechanism and method for stamping automobile wheel covers is provided to improve the efficiency of feeding and unloading and facilitate continuous stamping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic feeding and unloading mechanism for stamping automotive wheel covers includes... The storage bin has a feeding slide plate slidably connected to one end and a discharge plate connected to the other end. The discharge plate is provided with a feeding slide hole and a feeding chamber. The feeding slide hole is movably connected to a discharge rubber plate. The feeding chamber is equipped with a discharge through hole. One end of the feeding inclined table is located below the discharge through hole, and the other end of the feeding inclined table is connected to a stamping platform. A limiting baffle is provided, with one end of which is rotatably connected to the stamping platform and the other end of which is arranged opposite to the guide inclined table. The feeding clamp is equipped with a mold base, which is movably connected to the stamping platform. Material taking push rod, material taking push rod is movably connected to stamping platform, material taking push rod is connected to swirl rubber strip one, feeding pair clamp is provided with discharge port, stamping platform is connected to swirl rubber strip two, stamping platform is provided with positioning groove, positioning groove is connected to discharge port, positioning groove is embedded with swirl rubber strip two, swirl rubber strip one and swirl rubber strip two are arranged opposite to each other. The material collection box is movably connected to the stamping platform. The material collection box is equipped with several feeding slots, and the stamping platform is equipped with a discharge chute, which connects the feeding slots and the discharge port.

[0007] The material storage bin, through the sliding of the feeding slide, keeps the blank of the wheel cover disc always in contact with the feeding chamber of the discharge plate. The feeding chamber is a slotted hole in the wall of the feeding slide. The discharge plate on the feeding slide pushes the blank (outermost blank) against it from one side of the discharge hole to the other side. The feeding chamber on the other side of the discharge hole is opened through the discharge through hole below, allowing the feeding slide to move continuously until it leaves the feeding slide. After leaving the feeding slide, the blank loses its support and falls from the discharge through hole into the guide ramp. The surface of the guide ramp is horizontally inclined, allowing the blank to enter the stamping platform connected to the lower side along the guide ramp. Several feeding clamps are set up, and each feeding clamp has two oppositely arranged mold seats. The distance between the stamping platform and the limiting baffle is the discharge port. The limiting baffle prevents the blank from directly punching out of the guide. The inclined platform is erected between the blank holder and the die base, passing through the blanking port. The feeding clamps hold the blank upright on the stamping platform. The blank is stamped by moving the die base. The stamped blank is then moved by the die base to the second feeding strip. The push rod, through contact and push with the blank via the first feeding strip, propels the blank from the discharge port along the second feeding strip into the die base of the next feeding clamp for the next stage of stamping. The angle of the blank entering the next feeding clamp can be controlled by the first feeding strip, eliminating the need for manual adjustment of the stamping angle and ensuring high-efficiency, high-precision stamping. The movable collection box allows for automatic feeding and collection of blanks entering the unloading chute from the final discharge port via several feeding slots, facilitating rapid retrieval during unloading. This achieves automated feeding and retrieval in automotive wheel cover stamping operations, meeting the requirements for efficient continuous stamping and high-precision, fine-depth stamping.

[0008] Preferably, the inner wall of the storage bin is provided with mounting bosses, which are connected to guide rods. The feeding slide plate has a mounting hole, and the guide rod is inserted into the mounting hole. The storage bin is connected to a rotating mechanism, which is connected to a drive rod. The feeding slide plate is connected to a feeding pusher, and the drive rod is threadedly connected to the feeding pusher. The two opposing inner walls of the storage bin are connected to mounting bosses, and the billet is arranged and moved between the two mounting bosses. The mounting bosses are connected to the guide rod, allowing the feeding slide plate to move stably back and forth within the storage bin along the guide rod. The feeding pusher is mounted on the feeding slide plate and has a threaded hole. The drive rod has a thread that matches the threaded hole. The rotating mechanism drives the drive rod to rotate, causing the feeding pusher, threadedly connected to the drive rod, to move back and forth. This drives the feeding slide plate to push the billet to fill the gap at the discharge plate, preventing the billet from collapsing or tilting and failing to contact the discharge plate. This achieves the effect of improving the automation level of feeding and operational stability.

[0009] Preferably, the feed slide plate is connected to a support rod. One end of the support rod is connected to a limit plate, and the other end is connected to a contact push plate. A spring mechanism is sleeved on the support rod. One end of the spring mechanism abuts against the contact push plate, and the other end abuts against the feed slide plate. The contact push plate is connected to the end of the feed slide plate opposite to the billet. Through the spring mechanism connected by the support rod, the contact push plate and the feed slide plate are elastically buffered. This protects the discharge plate when the feed slide plate pushes the contact push plate to drive and limit the billet, preventing damage to the discharge plate from the hard impact thrust under mechanical force, and ensuring the management of impact energy under continuous thrust. This achieves the effect of protecting the feeding structure and extending the service life of the operating system.

[0010] Preferably, the discharge plate is connected to a mounting base, which has a mounting groove. A guide slide is slidably connected to the mounting groove, and the guide slide has a second mounting hole. The discharge plate is connected to a mounting base, and the mounting base is connected to a pressure rod, which is inserted into the second mounting hole. The storage box is connected to a rotating mechanism, which is connected to a drive rod. The feed slide is connected to a linkage table, and the drive rod is threadedly connected to the linkage table. The discharge plate rotates via the mounting groove on the mounting base, and the rotating mechanism drives the drive rod to rotate. This causes the linkage table connected to the guide slide to reciprocate along the drive rod under the drive of the rotating mechanism. Consequently, the guide slide can reciprocate directionally on the discharge plate. The discharge plate's structural stability is improved by the support of the mounting base. The mounting base, through the pressure rod, is inserted into the second mounting hole on the guide slide to stably reciprocate on the mounting base, following the guide slide. This achieves the effect of improving the stability and smoothness of the discharge operation.

[0011] Preferably, the guide slide is connected to a telescopic mechanism, which in turn is connected to a retraction rod. A pressure rod is sleeved with an elastic mechanism, one end of which is connected to the mounting base, and the other end to the guide slide. The pressure rod is connected to a retraction block, which is connected to the retraction rod. The pressure rod, through the elastic mechanism, maintains tight contact between the discharge plate on the mounting base and the blank, supported by the guide slide, making it easier to remove the blank. Driven by the telescopic mechanism and the retraction rod, the guide slide causes the retraction block to pull the pressure rod in the opposite direction, thus preventing friction between the discharge plate and the blank during resetting before the next blank contacts. This reduces wear on the discharge plate and improves the smoothness of the resetting process.

[0012] Preferably, the guide ramp is connected to a guide rod, the stamping platform is connected to a support frame, the support frame is connected to a rotating rod, and one end of the limiting baffle has a rotating hole. The rotating rod is inserted into the rotating hole. The support frame is connected to a telescopic mechanism two, which is connected to a push rod. The support frame is connected to a drive gear, and the push rod is connected to a drive rack. The drive gear and drive rack are meshed together. The guide rod on the guide ramp allows the blank falling on it to move along the guide rod to the designated stamping platform position. The support frame supports the rotation fulcrum of the limiting baffle through the rotating rod, allowing the telescopic mechanism two to rotate the drive gear through the push rod-connected rack, thereby causing the rotating rod to rotate. The limiting baffle, with the rotating rod as its fulcrum, raises the limiting baffle on the other side, allowing it to move automatically after the blank is sorted, preventing obstruction of the mold base's movement. This achieves the effect of improving the limiting and sorting performance during feeding, ensuring fast and smooth feeding, and fully preparing for stamping.

[0013] Preferably, the mold base includes mold base one and mold base two. A stamping platform is connected to telescopic mechanisms three and four. Mold base one is connected to telescopic mechanism three, and mold base two passes through a feeding slide hole and is connected to telescopic mechanism four. The lower side of the feeding clamp is connected to the stamping platform, and the upper side of the feeding clamp is connected to a feeding ramp. The mold base, including mold base one and mold base two, is arranged opposite to each other within the feeding clamp. Telescopic mechanism three drives mold base one, and telescopic mechanism four drives mold base two. The feeding ramp ensures that the blank correctly enters the feeding clamp through the discharge port. Telescopic mechanisms three and four stamp the blank and move to adjust its position, further ensuring feeding stability.

[0014] Preferably, the stamping platform is connected to a top support, which in turn is connected to a rotating mechanism three. The rotating mechanism three is connected to a drive rod three, and the top support is connected to a guide rail with a guide groove. A material-picking push rod is slidably connected to the guide groove, and the material-picking push rod is connected to a movable slider. The drive rod three is threadedly connected to the movable slider. The stamping platform supports the top support, and the rotating mechanism three on the top support drives the connected drive rod three to rotate. The drive rod three is threaded, and the material-picking push rod in the guide groove is connected to the movable slider, which has a threaded hole. Through the threaded connection between the drive rod three and the material-picking push rod, the connected rotating rubber strip one is driven to move synchronously and stably along the guide groove. This achieves the effect of ensuring a high degree of automation and improving the stability of material picking and transfer operations.

[0015] Preferably, the stamping platform is equipped with a movable support, and the collection box includes a base plate, side plates, and partitions. The movable support has a limiting slide groove, the base plate is slidably connected to the limiting slide groove, the side plates are connected to the base plate, and several partitions are provided and connected to the side plates and the base plate. The feeding slot is the space between the partitions. The base plate is connected to a slide table, and the stamping platform is connected to a rotating mechanism four. The rotating mechanism four is connected to a drive rod four, and the drive rod four is threadedly connected to the slide table. The stamping platform allows the base plate to move in a guiding manner through the limiting slide groove of the movable support. The side plates are connected to one side of the base plate, making the other side of the base plate open to facilitate material entry. The feeding slot is the gap between the partitions for the stamped wheel covers to be inserted from the open side. The rotating mechanism four drives the drive rod four to rotate. The drive rod four is threaded, and the slide table has a threaded hole. Through the threaded connection between the drive rod four and the slide table, the slide table moves with the base plate, so that the feeding slots correspond one by one to the unloading chute. Thus, the wheel covers are automatically arranged when unloading, and the vertical arrangement saves space. This achieves the effect of improving the automation of aggregate collection and the convenience of material retrieval.

[0016] This application also provides a method for an automatic feeding and unloading mechanism for stamping automotive wheel arches, comprising the following steps: S1: Loading: Load the billets one by one into the discharge plate through the storage box; S2: Feeding: The material is fed from the discharge plate and positioned and transferred by the guide inclined table; S3: Material preparation: The blank is prepared in the feeding clamp by means of the mold seat and the limiting baffle; S4: Stamping: Stamping the blank through a die holder; S5: Spinning: The wheel cover between the spinning rubber strip one and the spinning rubber strip two is rotated and enters the next feeding clamp while being stamped at the required angle by the feeding push rod; S6: Material collection: The finished product between the rotating rubber strip one and the rotating rubber strip two is driven into the feeding chute by the material pusher. The car wheel cover enters the feeding clamping groove along the feeding chute.

[0017] Inside the storage bin, several round metal blanks for automotive wheel covers are neatly stacked between the contact push plate and the discharge plate, with the foremost blank in close contact with the discharge plate inside the feeding slide hole. When feeding begins, the second rotating mechanism moves the linkage table on the second drive rod, causing the feeding slide to move from one end of the discharge plate's feeding slide hole to the other. During this movement, the foremost blank is carried out and moved within the feeding chamber until it reaches the discharge through hole. As the feeding slide continues to move, it moves away from the blank and the feeding slide hole, causing the blank to lose support and fall under its own weight through the discharge through hole into the guide ramp below. The second rotating mechanism then moves the feeding push table on the first drive rod, ensuring that the foremost blank in the storage bin remains in contact with the discharge plate. The second rotating mechanism resets the feeding slide plate along the mounting base. During the reset, the retraction rod connected by the first telescopic mechanism pushes the retraction block connected to the pressure rod outward, so that the discharge plate does not contact the frontmost blank during the reset. After the feeding slide plate is fully reset, the pressure rod is reset so that the discharge plate presses the blank again.

[0018] The billet passes through the inclined surface of the guide ramp and along the guide bar through the discharge port. The billet hits the limiting baffle and enters the feeding clamp and die holder in front of it, with the feeding ramp preventing the billet from falling out. After entering the feeding clamp, the telescopic mechanism two causes the push rod to push the drive rack, which in turn rotates the drive gear, causing the rotating rod to rotate under the support frame, thus raising the limiting baffle to create space for the stamping operation.

[0019] The telescopic mechanism four moves the mold base two, causing the mold base two to push the blank to be in contact with the mold base one. After resetting, it moves again to complete the die casting of the blank through the mold base, and then resets the mold base two. The mold base one moves so that the wheel cover after the initial stamping moves in the feeding clamp to the swivel strip two. At the same time, the rotating mechanism three is activated so that the take-up push rod, along with the swivel strip one, presses the wheel cover tightly. The mold base one is then reset. The continuously moving take-up push rod rolls the wheel cover out of the outlet and into the next feeding clamp between the mold base and the mold base. At this time, the wheel cover rotates to the required stamping angle within a fixed moving distance. The above operation can be repeated to make the wheel cover stamp again.

[0020] After stamping, the wheel cover is conveyed to the unloading chute by the material take-up pusher and leaves the first and second swirl strips along the slope. The wheel cover rolls into the corresponding feed slot of the collection box along the unloading chute, completing the stamping, material transfer and collection of the wheel cover.

[0021] The beneficial effects of this invention are: automated feeding and unloading of automotive wheel arch stamping operations; achieving efficient continuous stamping; high stamping precision applicable to fine stamping depth requirements; improved feeding automation and operational stability; protection of the feeding structure and extension of the operating system's lifespan; reduced wear on the discharge sheet while improving the smoothness of resetting; improved limiting and sorting performance during feeding, ensuring fast and smooth feeding to adequately prepare for stamping; and guaranteed high automation, improving the stability of unloading and transfer operations.

[0043] This application also provides a method for an automatic feeding and unloading mechanism for stamping automotive wheel arches, comprising the following steps: S1: Feeding: The billets are fed one by one into the discharge plate 3 through the storage box 1; S2: Feeding: The material is fed out by the discharge plate 3 and positioned and transferred by the guide inclined table 7; S3: Material preparation: The blank is prepared in the feeding clamp 11 plate by the mold seat and the limiting baffle 10; S4: Stamping: Stamping the blank through a die holder; S5: Rotating material: The wheel cover between rotating material strip 13 and rotating material strip 215 is rotated by the material pusher 12 and then punched between the next feeding clamps 11 at the required angle. S6: Material collection: The finished product between the first swirl rubber strip 13 and the second swirl rubber strip 15 is brought into the discharge chute 19 by the material pusher 12 during rotation, and the car wheel cover enters the feeding clamp 18 along the discharge chute 19.

[0044] The specific operation is as follows: Several automotive wheel cover metal disc blanks are neatly stacked between the contact push plate 27 and the discharge plate 3 inside the storage bin 1. At this time, the frontmost blank is in close contact with the discharge plate 6 in the feeding slide hole 4. When feeding begins, the rotating mechanism 2 34 is activated to drive the linkage table 36 to move on the drive rod 2 35, causing the feeding slide plate 2 to move from one end of the feeding slide hole 4 of the discharge plate 3 to the other end. During the movement, the frontmost blank is carried out and moved in the feeding chamber 5 until the blank moves to the discharge through hole 8. As the feeding slide plate 2 continues to move away from the blank and the feeding slide hole 4, the blank loses its support and falls into the guide inclined table 7 below under its own weight through the discharge through hole 8. The rotating mechanism 1 22 is activated to drive the feeding push table 24 to move on the drive rod 1 23, ensuring that the frontmost blank of the storage bin 1 is in contact with the discharge plate 3. The feeding slide plate 2 is reset along the mounting base 29 by rotating mechanism 2 34. During the reset, the retraction rod 38 connected by telescopic mechanism 1 37 pushes the retraction block 40 connected to the pressure rod 33 outward, so that the discharge plate 6 does not contact the frontmost blank during the reset. After the feeding slide plate 2 is fully reset, the pressure rod 33 is reset so that the discharge plate 6 presses the blank again.

[0045] The billet passes through the inclined surface of the guide ramp 7 and along the guide ramp 41 through the discharge port. The billet hits the limiting baffle 10 and enters the feeding clamp 11 and the front of the die holder 48 along the surface of the limiting baffle 10. The feeding ramp 52 prevents the billet from falling out. After entering the feeding clamp 11, the push rod 45 pushes the drive rack 47 through the telescopic mechanism 44. The drive gear 46 meshing with it rotates, driving the rotating rod 43 to rotate under the support frame 42, so that the limiting baffle 10 is raised to make room for the stamping operation.

[0046] Telescopic mechanism 41 moves mold base 2 49 to push the blank to be in contact with mold base 1 48, then resets and moves again to complete the die casting of the blank through the mold base, and then resets mold base 2 49. Move mold base 1 48 so that the wheel cover after the first stamping moves in the feeding clamp 11 to the spinning strip 2 15. At the same time, the rotating mechanism 3 54 is activated so that the take-up push rod 12, along with the spinning strip 1 13, presses the wheel cover, and then resets mold base 1 48. The continuously moving take-up push rod 12 rolls the wheel cover out from the outlet 14 and into the next feeding clamp 11 between the mold base and the mold base. At this time, the wheel cover rotates to the required stamping angle within a fixed moving distance, and the above operation can be repeated to make the wheel cover stamp again.

[0047] After stamping, the wheel cover is conveyed to the unloading chute 19 by the material take-up push rod 12 and leaves the first swirl strip 13 and the second swirl strip 15 along the inclined surface. The wheel cover rolls into the corresponding feed clamping groove 18 of the collection box 17 along the unloading chute 19, completing the stamping, material transfer and collection of the wheel cover.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
