[0016] The advantages of this application are: (1) This application realizes the automatic and precise feeding of rivets. The lifting plate is driven to reciprocate by the hydraulic rod. With the structure of the inclined lifting plate surface, guide frame and baffle, the accumulated rivets can be lifted one by one and accurately fed into the U-shaped groove of the fixed plate. The linkage mechanism is used to convert the movement of the lifting plate into the reciprocating movement of the push block. After the rivet falls into the U-shaped groove, the push block can accurately push it to the center position of the chuck. This effectively avoids the errors or inefficiencies that may occur with manual feeding, and provides a stable and accurate supply of raw materials for subsequent processing. It significantly improves the automation level and production cycle of the equipment.

[0017] (2) By setting up a moving component, this application realizes the one-way intermittent conveying of rivets using existing motion, which improves the integration of equipment and energy efficiency. The up-and-down reciprocating motion of the lifting plate is used as the power source. Through the cooperation of the toothed plate, gear, ratchet and pawl mechanism, the linear motion of the lifting plate is converted into the one-way intermittent rotational motion of the transmission belt, thereby driving the chuck and rivets to move step by step to the next station. This not only realizes precise intermittent feeding and perfectly matches the pushing action, but also eliminates the need for additional drive motors and other power devices, simplifying the structure, reducing energy consumption, and demonstrating a high degree of functional integration and motion reuse.

[0018] (3) By setting up a stabilizing component, this application effectively ensures the processing accuracy. The push force of the mounting column on the arc plate when it moves is used as a trigger signal. Through a set of lever transmission mechanisms, the signal is converted into the action of the stabilizing block pressing against the bottom of the mounting column. This process is synchronized with the downward movement of the cutting disc. It provides rigid support for the rivet at the moment of cutting, preventing it from being displaced or shaking due to vibration, thereby ensuring the flatness and dimensional accuracy of the cut surface. It realizes the intelligent linkage between the stabilizing action and the processing process, without the need for separate control, which significantly improves the processing stability of the equipment and the consistency of the products.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1, see Figures 1-7 This embodiment provides a rivet processing and forming device, including a worktable 1 and a bottom fixed support leg 2 of the worktable 1. An L-shaped plate 35 is fixedly connected to the upper end of the workbench 1. A hydraulic rod A31 is fixedly connected to the top of the L-shaped plate 35. An L-shaped block 32 is fixedly connected to the output end of the hydraulic rod A31. A motor 33 is fixedly connected to the outer wall of the L-shaped block 32. A cutting disc 34 is fixedly connected to the output end of the motor 33. A fixed plate 41 is fixedly connected to the upper end of the workbench 1. A guide frame 42 is fixedly connected to the side of the fixed plate 41. A hydraulic rod B43 is fixedly connected to the bottom of the workbench 1. A lifting plate 44 is fixedly connected to the output end of the hydraulic rod B43. A U-shaped groove 45 is opened on the top of the fixed plate 41. A fixed frame 46 is fixedly connected to the side of the fixed plate 41. A slider 47 is slidably connected inside the fixed frame 46. A connecting rod A48 is hinged to the side of the lifting plate 44. A connecting shaft 49 is rotatably connected to the other end of the connecting rod A48. The connecting shaft 49 is rotatably connected to the slider 47. A connecting rod A410 is fixedly connected to the inner side of the slider 47. A push block 411 is fixedly connected to the other end of the connecting rod A410.

[0028] The fixed frame 46 has a sliding groove 412 on its side. The connecting shaft 49 is slidably connected to the sliding groove 412. The sliding groove 412 extends longitudinally along the side wall, and the connecting shaft 49 is precisely fitted inside the sliding groove 412, so that it can smoothly slide along the sliding groove 412.

[0029] The upper end of the lifting plate 44 slides through the guide frame 42. The upper sides of the lifting plate 44 are from high to low, and the side of the lifting plate 44 closer to the fixed plate 41 is lower. As a result, the rivets at the upper end of the lifting plate 44 will slide under the action of gravity after they lose their obstruction to the fixed plate 41.

[0030] A baffle 413 is fixedly connected to the upper end of the guide frame 42 near the fixed plate 41. The height of the baffle 413 is higher than the height of the fixed plate 41. By setting the guide frame 42 and the baffle 413, the rivets can be effectively prevented from accidentally slipping off the lifting plate 44 during the conveying process, ensuring that the rivets can accurately enter the U-shaped groove 45.

[0031] In practical use, the above-mentioned equipment first places multiple rivets inside the guide frame 42. Then, under the action of gravity, the rivets will slide to the lower side of the guide frame 42. The rivet at the bottom will slide to the upper end of the lifting plate 44. The lifting plate 44 is driven to move up and down by the hydraulic rod B43. When the lifting plate 44 rises, its inclined upper surface will lift the rivet material located in the guide frame 42 upward. Under the limiting action of the baffle 413, when the lowest side of the lifting plate 44 coincides with the height of the fixed plate 41, the rivet material will fall accurately into the U-shaped groove 45 at the top of the fixed plate 41. As the lifting plate 44 rises, it drives the lower end of the connecting rod A48 to move upward. The connecting rod A48 then pushes the slider 47 along the slide groove 412 in the fixed frame 46 away from the U-shaped groove 45 via the connecting shaft 49. At this time, the push block 411 moves away from the U-shaped groove 45 simultaneously under the action of the connecting rod A410, making room for the rivet material to fall into the U-shaped groove 45. When the lifting plate 44 returns to its original position, the lower end of the connecting rod A48 moves downward, which in turn pulls the slider 47 in the fixed frame 46 via the connecting shaft 49. Sliding towards the U-shaped groove 45, the slider 47 drives the connecting rod A410 and the push block 411 to move together. The push block 411 then moves the rivet material in the U-shaped groove 45 towards the center of the chuck 514, allowing the rivet to enter the center of the chuck 514. Through the cooperation of the push block 411 and the U-shaped groove 45, the rivet material is accurately pushed, avoiding the positional deviation that may occur during manual feeding. This provides a stable supply of raw materials for subsequent processing steps and greatly improves the automation and accuracy of feeding.

[0032] Example 2, see Figures 1-7 In this embodiment, based on embodiment one, a moving component 5 is assembled on the upper end of the workbench 1. The moving component 5 includes two fixed blocks 51, which are fixedly connected to the upper end of the workbench 1. A rotating shaft 52 is rotatably connected to the outer wall of the two fixed blocks 51. A transmission wheel A53 and a transmission wheel B54 are respectively fixedly sleeved on the outer wall of the two rotating shafts 52. A transmission belt 55 is wound around the outer wall of the transmission wheel A53 and the transmission wheel B54. A ratchet 56 is fixedly connected to one end of one rotating shaft 52. A gear 57 is rotatably connected to the inner side of the fixed block 51. A pawl 58 is hinged to the inner wall of the gear 57. A connecting rod B59 is fixedly connected to the bottom of the lifting plate 44. A toothed plate 510 is fixedly connected to the other end of the connecting rod B59. A connecting rod C513 is fixedly connected to the outer wall of the transmission belt 55. A mounting column is fixedly connected to the other end of the connecting rod C513. A chuck 514 is fixedly connected to the upper end of the mounting column.

[0033] A spring 511 is fixedly connected to the inner side of the gear 57. The other end of the spring 511 is fixedly connected to the pawl 58. The spring 511 is always in a slightly tense state, providing a continuous elastic force to the pawl 58, ensuring that the pawl 58 can stably engage with the tooth groove of the ratchet 56, effectively preventing the ratchet 56 from reversing in the non-drive state, thereby ensuring the unidirectionality and stability of the transmission.

[0034] The upper end of the workbench 1 is provided with an opening 512. The toothed plate 510 moves through the opening 512. The toothed plate 510 meshes with the gear 57. The lifting motion of the toothed plate 510 is converted into the rotational motion of the gear 57, which in turn drives the rotating shaft 52 to rotate intermittently through the cooperation of the pawl 58 and the ratchet 56.

[0035] In practical use, when the lifting plate 44 moves up and down under the drive of the hydraulic rod B43, the connecting rod B59 at its bottom will drive the toothed plate 510 to move up and down synchronously within the opening 512. When the toothed plate 510 moves upward, it meshes with the gear 57, driving the gear 57 to rotate. At this time, the pawl 58 hinged to the inner wall of the gear 57 will engage with the ratchet 56 under the action of the spring 511, thereby driving the ratchet 56 to rotate with the gear 57. The rotation of the ratchet 56 will drive the rotating shaft 52 fixedly connected to it to rotate, thereby causing the transmission wheel A53 on the rotating shaft 52 to rotate. Through the transmission action of the transmission belt 55, the transmission wheel B54 and the rotating shaft 52 on the other side will also rotate. The movement of the transmission belt 55 will drive the mounting column and chuck 514 to move through the connecting rod C513, realizing the position delivery of the rivets on the chuck 514. When the toothed plate 510 moves up and down with the lifting plate 44, it will drive the mounting column and chuck 514 to move, thereby realizing the position delivery of the rivets on the chuck 514. When moving downwards, the toothed plate 510 drives the gear 57 to rotate in the opposite direction. At this time, the pawl 58 slides on the back of the ratchet 56 and compresses the spring 511, so that the ratchet 56 will not rotate in the opposite direction. This ensures that the transmission belt 55 and the chuck 514 will not move in the opposite direction during the descent of the lifting plate 44, realizing the unidirectional intermittent feeding of the chuck 514. At the same time, it is convenient to push the rivet into the chuck 514. This design cleverly uses the up-and-down reciprocating motion of the lifting plate 44 as a power source. Without the need for an additional drive device, the automatic intermittent feeding of the rivet can be completed, improving the integration of the equipment and the energy utilization efficiency, and ensuring that the rivet can move accurately to the next processing station according to the preset rhythm during the processing.

[0036] Example 3, see Figures 1-7 In this embodiment, based on Embodiment 1, a stabilizing component 6 is assembled on the upper end of the workbench 1. The stabilizing component 6 includes an elastic telescopic rod 61, which is fixedly connected to the inner side of the L-shaped plate 35. A moving rod 62 is fixedly connected to the other end of the elastic telescopic rod 61, and an arc-shaped plate 63 is fixedly connected to the other end of the moving rod 62. An installation rod 64 is fixedly connected to the upper end of the workbench 1. An installation shaft 65 is rotatably connected to the inner side of the installation rod 64. A swing rod 66 is fixedly sleeved on the outer wall of the installation shaft 65. Two movable grooves 67 are opened on the outer side of the swing rod 66. A sliding shaft A 68 is fixedly connected to the outer wall of the moving rod 62. A sliding rod 610 is provided on the inner side of the installation rod 64. A sliding shaft B 69 is fixedly connected to the outer wall of the sliding rod 610. A stabilizing block 612 is fixedly connected to the end of the sliding rod 610 near the installation column.

[0037] Sliding shaft A68 is slidably connected to the inner side of the lower movable groove 67, and sliding shaft B69 is slidably connected to the inner side of the upper movable groove 67. Both can move smoothly and steadily within their respective grooves, ensuring the coordination and stability of the entire device during operation.

[0038] A limiting block is fixedly connected to the inner side of the mounting rod 64, and a limiting groove 613 is opened on the outer wall of the slide rod 610. The limiting block is slidably connected inside the limiting groove 613, and the limiting block can be smoothly slidably connected in the internal structure of the limiting groove 613.

[0039] When the above equipment is used, when the hydraulic rod A31 drives the L-shaped block 32 to move the cutting disc 34 downward to perform cutting operations, when the mounting column connected to the lower side of the transmission belt 55 moves to the middle of the worktable 1, the mounting column will push the arc plate 63 to move outward, and the arc plate 63 will drive the moving rod 62 to move synchronously. At this time, the elastic telescopic rod 61 is compressed and generates elastic restoring force. During the movement of the moving rod 62, the sliding shaft A68 on its outer wall will slide in the lower movable groove 67, thereby driving the swing rod 66 to rotate around the mounting shaft 65. As the swing rod 66 rotates, the upper movable groove 67 pushes the sliding shaft B69 to move, which in turn drives the sliding rod 610 to slide closer to the mounting post on the inner side of the mounting rod 64. During this process, the limiting block on the inner side of the mounting rod 64 slides in the limiting groove 613 on the outer wall of the sliding rod 610, which guides and limits the movement of the sliding rod 610, ensuring that the sliding rod 610 can move smoothly and accurately. The stabilizing block 612, which is fixedly connected to the end of the sliding rod 610 near the mounting post, will move closer to and press against the bottom of the upper mounting post. Through the close contact between the stabilizing block 612 and the bottom of the mounting post, the shaking or displacement that the mounting post may generate during the cutting process is effectively limited, providing a stable support for the rivets on the chuck 514 and avoiding cutting accuracy deviation caused by vibration. When the cutting is completed and the hydraulic rod A31 drives the cutting disc 34 to move upward and reset, the elastic restoring force of the elastic telescopic rod 61 will push the moving rod 62 and the arc plate 63 to move in the opposite direction. The sliding shaft A68 slides in the opposite direction in the lower movable groove 67, causing the swing rod 66 to rotate in the opposite direction around the mounting shaft 65. Then, through the upper movable groove 67, it pulls the sliding shaft B69 and the sliding rod 610 to move away from the mounting column. The stabilizing block 612 then detaches from the bottom of the mounting column, releasing the fixing of the mounting column, so that the transmission belt 55 can drive the next mounting column and rivet to the processing position. This design of the stabilizing component 6 utilizes the combination of the driving force of the cutting action and the elastic restoring force to realize the automated control of stabilization and release during the rivet processing, further improving the stability and reliability of the equipment processing, and ensuring the flatness of the rivet cutting surface and the accuracy of the processing dimensions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
