Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a rivet stamping machine with adjustable stamping position. Background Technology

[0002] In riveting processes, rivet punching machines are crucial equipment, widely used for joining various sheet metal parts. With the rapid development of industrial production, the demands for riveting efficiency and precision are constantly increasing. However, existing technologies for traditional rivet punching machines present some significant technical problems, limiting their application scope and production efficiency.

[0003] First, the position of the stamping mechanism on existing riveting presses is often fixed and cannot be freely adjusted according to actual needs. This results in the need to frequently change the press or adjust the position of the sheet metal when riveting sheets of different sizes or positions, which greatly reduces production efficiency. For example, in some cases, it may be necessary to rivet at different positions on the same sheet metal, or to rivet different through holes on multiple sheets of sheet metal at the same time. Traditional presses, due to the fixed position of the stamping mechanism, cannot meet these diverse needs.

[0004] Secondly, existing riveting stamping machines have shortcomings in the positioning of sheet metal and the precise placement of rivets during the riveting process. Inaccurate sheet metal positioning or misaligned rivet placement during riveting can lead to poor riveting results or even damage to the sheet metal or rivets. Traditional stamping machines lack effective positioning and guiding mechanisms, making it difficult to guarantee the accuracy and stability of the riveting process. Therefore, this paper provides a riveting stamping machine with adjustable stamping position to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rivet stamping machine with adjustable stamping position to address the shortcomings of the existing technology, so as to solve the technical problems that the position of the stamping mechanism on the existing rivet stamping machine cannot be freely adjusted, and the plate is not accurately positioned during the riveting process.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A riveting press with adjustable stamping position includes a frame, a stamping table for supporting stacked sheet metal, and a first support frame and a second support frame that are laterally slidably disposed on the frame. Both the first support frame and the second support frame are equipped with a stamping mechanism for riveting the sheet metal stacked on the stamping table.

[0008] The stamping mechanism includes a lifting rod that can move up and down and a pressing member located at the bottom of the lifting rod for pressing the rivet. The bottom of the pressing member is provided with an upper spring pin that can elastically extend and retract. A support member is mounted on the first support frame and is located directly below the upper spring pin. The top of the support member is provided with a lower spring pin that is coaxial with the upper spring pin and can elastically extend and retract. The elastic force of the upper spring pin is greater than the elastic force of the lower spring pin.

[0009] Furthermore, the frame is provided with a horizontally arranged slide rail, and the first support frame and the second support frame are both slidably mounted on the slide rail. A servo motor is also installed, and the output shaft of the servo motor is provided with a positive and negative threaded rod with a length direction parallel to the length direction of the slide rail. Different threaded portions on the positive and negative threaded rods are respectively threadedly connected to the first support frame and the second support frame.

[0010] Furthermore, the top of the lower spring ejector pin is formed with a guide pin that can be inserted into the bottom of the rivet. The diameter of the guide pin is smaller than the diameter of the lower spring ejector pin, so that the top of the lower spring ejector pin is formed with a boss for opening the bottom of the rivet. The top surface of the boss is inclined. The bottom of the pressing part is the pressing part.

[0011] Furthermore, the stamping mechanism also includes a feeding mechanism mounted on the first support frame. The feeding mechanism is equipped with a rivet flow channel for feeding the rivets inside it one by one to the rivet flow channel directly below the upper spring ejector pin. The top of the rivet flow channel is rotatably mounted on the feeding mechanism, and the axis of rotation is arranged laterally. A wedge block is provided on the side of the rivet flow channel near the lifting rod. An abutment rod is mounted on the lifting rod for pushing the wedge block to rotate the rivet flow channel.

[0012] Furthermore, the end of the rivet flow channel is provided with a rivet insertion station located directly below the upper spring ejector pin, and is also equipped with a material blocking component for blocking the conveyed rivets to the rivet insertion station.

[0013] Furthermore, the material blocking component includes a fixed block disposed on the rivet flow channel, a movable link is rotatably disposed on the fixed block, and the axis of rotation of the movable link is arranged vertically. An L-shaped rotating member is disposed at the end of the movable link, one end of the rotating member is a material blocking part for blocking the rivet, and a spring is disposed between the other end of the rotating member and the fixed block for resetting the rotating member after rotation.

[0014] Furthermore, it also includes a fixing member disposed on the first support frame, the support member being disposed on the fixing member, and the fixing member being equipped with a dust-collecting component located around the lower spring pin for collecting metal dust.

[0015] Furthermore, the top of the fastener is equipped with an elastic element for cushioning the sheet metal during the riveting process, and a cushioning pad is provided on the top surface of the stamping table.

[0016] Furthermore, a long strip-shaped relief groove is formed on the stamping table, with the length direction of the relief groove parallel to the length direction of the slide rail, and the fixing component is placed in the relief groove.

[0017] Furthermore, the dust collection component includes a fixed base, the top surface of which is formed with a first collection groove for collecting metal dust. The first collection groove is annular and coaxially arranged with the lower spring pin. The top of the fixed base is provided with a detachable cover for covering the first collection groove. The top surface of the cover is formed with a plurality of suction holes for sucking metal dust into the first collection groove. The fixed base is also provided with a connecting pipe, and a suction channel for connecting the two is provided between the connecting pipe and the first collection groove.

[0018] The beneficial effects of this invention are as follows: In use, multiple stacked plates can be placed on the stamping table along the lateral movement direction of the first and second support frames. The through holes on different plates are aligned with the stamping mechanisms on the first and second support frames, respectively. Simultaneously operating the stamping mechanisms on both sides allows for the simultaneous riveting of two stacked plates, improving the riveting efficiency of this stamping machine. Furthermore, larger plates can be stacked on the stamping table. By controlling the movement of the first and second support frames to adjust the distance between the stamping mechanisms on both sides, this distance is made consistent with the distance between the through holes on the plates. At this point, larger plates can be stacked on the stamping table, aligning a pair of through holes on the plates with the stamping mechanisms on both sides. Simultaneously operating the stamping mechanisms on both sides allows for the riveting of larger plates, reducing riveting steps and operations, and further improving the riveting efficiency of this stamping machine.

[0019] Specifically, after the stacked sheet metal is placed on the stamping table, the lower spring ejector pin passes through the through hole in the sheet metal to position it. Then, the rivet is placed directly below the upper spring ejector pin and above the through hole in the sheet metal. Next, the lifting rod is controlled to move downwards, causing the lifting rod to move downwards along with the pressing component and the upper spring ejector pin. This allows the upper spring ejector pin to pass through the rivet and move downwards with the rivet. Once the bottom end of the rivet contacts the top end of the lower spring ejector pin, the bottom end of the upper spring ejector pin also contacts the top end of the lower spring ejector pin. When the elastic force of the upper spring pin is greater than that of the lower spring pin, the pressing component continues to move downward, pressing the rivet. The lower spring pin on the support retracts downward, pressing the rivet into the through hole on the plate. After the lower spring pin retracts to its lowest point, the pressing component continues to move downward, causing the upper spring pin to retract upward on the pressing component. At this time, the pressing component presses the rivet, and the top of the lower spring pin pushes the bottom of the rivet open, thus achieving the riveting process for the stacked plates.

[0027] The following is a detailed description of a riveting stamping machine with adjustable stamping position according to the present invention, with reference to the accompanying drawings.

[0028] like Figure 1As shown, an embodiment of the present invention, a riveting press with adjustable stamping position, includes a frame 1, a stamping table 2 for supporting stacked plates 11, and a first support frame 4 and a second support frame 5 slidably disposed on the frame 1. Both the first support frame 4 and the second support frame 5 are equipped with a stamping mechanism 6 for riveting the stacked plates 11 placed on the stamping table 2. First, multiple sheet metal plates 11 are stacked on the stamping table 2, with the through holes on the sheet metal plates 11 aligned with the execution end of the stamping mechanism 6. Then, the stamping mechanism 6 is run to perform riveting on the stacked sheet metal plates 11, thus riveting multiple sheet metal plates 11 together. Alternatively, multiple stacked sheet metal plates 11 can be placed on the stamping table 2 along the movement direction of the first support frame 4 and the second support frame 5, with the through holes on different sheet metal plates 11 aligned with the stamping mechanisms 6 on the first support frame 4 and the second support frame 5, respectively. Simultaneously, the stamping mechanisms 6 on both sides are run to achieve simultaneous riveting on two stacked sheet metal plates 11, thereby improving the riveting efficiency of this stamping machine. In addition, larger sheet metal 11 can be stacked on the stamping table 2. For example, the larger sheet metal 11 has several pairs of through holes formed on it. The first support frame 4 and the second support frame 5 are controlled to move towards each other or away from each other to adjust the distance between the two stamping mechanisms 6 so that the distance is consistent with the distance between the pair of through holes on the sheet metal 11. At this time, the larger sheet metal 11 can be stacked on the stamping table 2 so that the pair of through holes on the sheet metal 11 are aligned with the execution ends of the two stamping mechanisms 6. The stamping mechanisms 6 on both sides are operated at the same time to realize the riveting process of the larger sheet metal 11, reducing the riveting process and operation, and further improving the riveting efficiency of this stamping machine.

[0029] However, in order to control the movement of the first support frame 4 and the second support frame 5 in directions that bring them closer to or further away from each other, the frame 1 is provided with a transversely arranged slide rail 8. Both the first support frame 4 and the second support frame 5 are slidably mounted on the slide rail 8. A servo motor 9 is also installed, and the output shaft of the servo motor 9 is provided with a positive and negative threaded rod 10 whose length direction is parallel to the length direction of the slide rail 8. Different threaded portions on the positive and negative threaded rod 10 are threadedly connected to the first support frame 4 and the second support frame 5, respectively. When the servo motor 9 is operated, driving the positive and negative threaded rod 10, the first support frame 4 and the second support frame 5 can be controlled to move laterally on the slide rail 8 in directions that bring them closer to or further away from each other, so as to adjust the position and spacing of the two side stamping mechanisms 6 to adapt to sheet metal 11 of different sizes and positions.

[0030] The stamping mechanism 6 mounted on the first support frame 4 and the stamping mechanism 6 mounted on the second support frame 5 have the same result and operate in the same way, such as... Figure 2As shown, the stamping mechanism 6 mounted on the first support frame 4 includes a lifting device 61, on which a lifting rod 62 is provided. By operating the lifting device 61, the lifting rod 62 can be controlled to move up and down. A pressing member 63 for pressing the rivet 12 is mounted at the bottom end of the lifting rod 62, and an upper spring pin 631 that can elastically extend and retract is coaxially provided at the bottom end of the pressing member 63. A fixing member 64 is mounted on the first support frame 4 and is positioned directly below the upper spring pin 631. A support member 653 is mounted on the fixing member 64, and a lower spring pin 65 that can elastically extend and retract is provided at the top end of the support member 653 and is coaxially arranged with the upper spring pin 631. A long strip-shaped relief groove 7 is formed on the stamping table 2. The length direction of the relief groove 7 is parallel to the length direction of the slide rail 8, and the fixing member 64 is placed in the relief groove 7. After the stacked sheet metal 11 is placed on the stamping table 2, the lower spring ejector pin 65 passes through the through hole in the sheet metal 11 to position the sheet metal 11. Then, the rivet 12 is placed directly below the upper spring ejector pin 631 and directly above the through hole in the sheet metal 11. Then, the lifting device 61 is operated to control the lifting rod 62 to move downward. The lifting rod 62 moves downward together with the pressing part 63 and the upper spring ejector pin 631, so that the upper spring ejector pin 631 passes through the rivet 12 and moves downward together with the rivet 12. At the same time, the bottom end of the rivet 12 contacts the top end of the lower spring ejector pin 65, and the bottom end of the upper spring ejector pin 631 also contacts the lower spring ejector pin 65. The upper spring pin 631 extends and retracts with greater force than the lower spring pin 65. When the pressing member 63 continues to move downward, it presses down on the rivet 12. The lower spring pin 65 on the support member 653 retracts downward, pressing the rivet 12 into the through hole on the plate 11. After the lower spring pin 65 retracts to its lowest point, the pressing member 63 continues to move downward, causing the upper spring pin 631 to retract upward on the pressing member 63. At this time, the pressing member 63 continues to press down on the rivet 12, pushing the bottom end of the rivet 12 open through the top of the lower spring pin 65, thus achieving the riveting process on the stacked plate 11. When the pressing member 63 is controlled to return to its upward position, the upper spring pin 631 and the lower spring pin 65 automatically return to their original positions, so that the riveted plate 11 placed on the stamping table 2 can be removed. When adjusting the distance between the two stamping mechanisms 6, the fixing member 64 moves laterally in the relief groove 7. The relief groove 7 is set to allow the fixing member 64 to make room, which facilitates the adjustment of the riveting position.

[0031] In this embodiment, the top end of the lower spring pin 65 is formed with a guide pin 651 that can be inserted into the bottom end of the rivet 12. The diameter of the guide pin 651 is smaller than the diameter of the lower spring pin 65, so that the top end of the lower spring pin 65 is formed with a boss 652 for opening the bottom end of the rivet 12. The top surface of the boss 652 is inclined. The bottom end of the pressing member 63 is the pressing part 632. The lifting rod 62 moves downward together with the pressing member 63 and the upper spring pin 631, so that the upper spring pin 631 passes through the rivet 12 and moves downward together with the rivet 12. After the guide pin 651 is inserted into the bottom end of the rivet 12, the bottom end of the rivet 12 contacts the boss 652, and the bottom end of the upper spring pin 631 also contacts the top end of the guide pin 651. When the pressing member 63 continues to move downward, the lower spring pin 65 on the support member 653 retracts downward, thereby pressing the rivet 12 against the plate. Inside the through hole on 11, after the lower spring pin 65 retracts downward to its lowest point, the pressing member 63 continues to move downward, causing the upper spring pin 631 to retract upward on the pressing member 63. At this time, the pressing part 632 at the bottom of the pressing member 63 presses the top of the rivet 12, and the inclined boss 652 pushes the bottom of the rivet 12 open. By setting the guide pin 651 and the boss 652, the accuracy of riveting is improved, and the bottom of the rivet 12 is opened more evenly and aesthetically.

[0032] Additionally, an elastic element 66 is installed on the top of the fastener 64 to cushion the sheet metal 11 during the riveting process. A buffer pad 3 is provided on the top surface of the stamping table 2, which also serves to cushion the sheet metal 11 during the riveting process. When the pressing element 63 presses the rivet 12 to push the bottom end of the rivet 12 to open it, the sheet metal 11 will also be subjected to a certain pressing force. However, in order to prevent damage to the sheet metal 11, the elastic element 66 and the buffer pad 3 are provided to cushion the stacked sheet metal 11, which further improves the efficiency of riveting.

[0033] In order to automatically position the rivets 12 directly below the upper spring ejector pin 631, the stamping mechanism 6 also includes a feeding mechanism 67 mounted on the first support frame 4. The feeding mechanism 67 is equipped with a rivet flow channel 68 for feeding the rivets 12 inside it one by one to the area directly below the upper spring ejector pin 631. The top of the rivet flow channel 68 is rotatably mounted on the feeding mechanism 67, and the axis of rotation is arranged laterally. A wedge block 610 is provided on the side of the rivet flow channel 68 near the lifting rod 62. The lifting rod 62 is equipped with an abutment rod 611 for pushing the wedge block 610 to rotate the rivet flow channel 68. The feeding mechanism 67 is operated to feed rivets 12 one by one onto the rivet flow channel 68. The first rivet 12 is conveyed through the rivet flow channel 68 and placed directly below the upper spring pin 631 after being delivered to the end of the rivet flow channel 68. Then, the lifting rod 62 is controlled to move downward. The lifting rod 62 moves downward together with the pressing member 63 and the upper spring pin 631, so that the upper spring pin 631 passes through the rivet 12 placed at the end of the rivet flow channel 68 and moves downward together with the rivet 12. During the downward movement, the lifting rod 62 and the abutment rod 611 contact the wedge block 610, which pushes the rivet flow channel 68 to rotate on the feeding mechanism 67. This causes the end of the rivet flow channel 68 to be removed from directly below the upper spring pin 631, and the rivet 12 automatically disengages from the end of the rivet flow channel 68 to facilitate the pressing process of the rivet.

[0034] Furthermore, a rivet insertion station 681 is provided at the end of the rivet flow channel 68, located directly below the upper spring ejector pin 631. A material blocking component 69 is also provided to block the incoming rivet 12 to the rivet insertion station 681. When the rivet flow channel 68 rotates to allow its end to retract, the first rivet 12 automatically disengages from the end of the rivet flow channel 68, and the next rivet 12 is blocked by the material blocking component 69 to the rivet insertion station 681 in preparation for the next riveting operation.

[0035] The feeding mechanism 67, rivet flow channel 68, wedge block 610, and abutting rod 611 are all prior art. For details of the specific structure of the feeding mechanism 67, please refer to application number CN202221881283.1 (A rivet flow channel feeding mechanism); for details of the specific structure and cooperation relationship of the rivet flow channel 68, wedge block 610, and abutting rod 611, please refer to application number CN201920969740.4 (A rivet punching machine with automatic rivet flow channel avoidance mechanism), which will not be elaborated here.

[0036] A dust-collecting component 612 is installed on the fixing component 64, which is located around the lower spring pin 65 and is used to collect metal dust. Depending on the different metal materials of the rivet 12, metal dust may be generated during the riveting process. In order to prevent it from affecting the subsequent riveting effect, the dust-collecting component 612 is operated to collect the generated metal dust, thereby improving the riveting effect.

[0037] like Figure 3 As shown, the baffle component 69 includes a fixed block 691 disposed on the rivet flow channel 68. A movable link 692 is rotatably disposed on the fixed block 691, and the axis of rotation of the movable link 692 is arranged vertically. An L-shaped rotating member 693 is disposed at the end of the movable link 692. One end of the rotating member 693 is a baffle portion 694 for blocking the rivet 12. A spring 695 is disposed between the other end of the rotating member 693 and the fixed block 691 for resetting the rotating member 693 after rotation. The rivet flow channel 68 conveys a number of rivets 12. After the first rivet 12 is conveyed to the rivet insertion station 681, it is blocked by the stop part 694. At this time, the lifting rod 62 can be controlled to move downward. The lifting rod 62 moves downward together with the pressing part 63 and the upper spring pin 631, so that the upper spring pin 631 passes through the rivet 12 located at the end of the rivet flow channel 68 and moves downward together with the rivet 12. During the downward movement, the lifting rod 62 and the abutment rod 611 contact the wedge block 610, and push the rivet flow channel 68 to rotate on the feeding mechanism 67. The rotating part 693 moves together with the rivet, causing the end of the rivet channel 68 to exit directly below the spring pin 631. The rivet 12 automatically disengages from the end of the rivet channel 68. During the disengagement process, the stop part 694 on the rotating part 693 is automatically pushed, causing the rotating part 693 to rotate on the fixed block 691. At this time, the spring 695 is compressed. When the rivet 12 is completely disengaged from the end of the rivet channel 68, the rotating part 693 can be rotated in the opposite direction to reset under the action of the compressed spring 695, so as to stop the next rivet 12 to the rivet insertion station 681.

[0038] like Figure 4 As shown, the dust collection component 612 includes a fixed base 6121. The top surface of the fixed base 6121 is formed with a first collection groove 6122 for collecting metal dust. The first collection groove 6122 is annular and coaxially arranged with the lower spring pin 65. A detachable cover 6123 is provided on the top of the fixed base 6121 for covering the first collection groove 6122. The top surface of the cover 6123 is formed with a plurality of dust collection holes 6124 for sucking metal dust into the first collection groove 6122. The fixed base 6121 is also provided with a connecting pipe 6126 for communicating with a suction device (not shown in the figure). A suction channel 6125 is provided between the connecting pipe 6126 and the first collection groove 6122 to connect the two. While riveting the rivet 12, the suction device (not shown in the figure) is operated to generate suction through several suction holes 6124, which suck the generated metal dust into the first collection tank 6122 for collection. After the cover 6123 is removed from the fixing base 6121, the metal dust in the first collection tank 6122 can be cleaned.

[0039] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0040] The above description is only a preferred embodiment of this utility model.
