Description

Technical Field

[0001] This invention relates to the field of easy-open lid production equipment technology, specifically to a stamping device for a multi-channel high-speed production line for easy-open lids. Background Technology

[0002] The core purpose of the stamping device in the multi-channel high-speed production line for easy-open lids is to achieve continuous and high-precision processing of coiled metal sheets (easy-open lid raw materials) in the production line of the conveying device. The metal sheet conveying deviation is corrected by the alignment component, and the auxiliary guide component and the feeding component work together to complete stable clamping and conveying. Finally, the stamping unit composed of upper and lower dies with misaligned tooth grooves accurately cuts the continuous metal sheet into segmented metal sheets that meet the requirements of subsequent easy-open lid forming, and the segmented metal sheets are conveyed to the next process by the conveying device.

[0003] However, existing devices lack precise and adaptive alignment structures. When the rolled metal sheets are unrolled, they are prone to lateral displacement due to the curling stress of the roll itself and uneven conveying traction. At the same time, existing alignment mechanisms are mostly designed with fixed spacing or manual adjustment spacing, which cannot quickly adapt to metal sheets of different widths, resulting in low adjustment efficiency and easy adjustment deviations.

[0004] Furthermore, the lack of stable lateral constraints during the metal sheet conveying process exacerbates the offset problem during high-speed conveying, causing the metal sheet to fail to accurately enter the stamping unit, which in turn leads to subsequent shearing position deviations.

[0005] Furthermore, the feeding and guiding mechanisms of existing devices are mostly rigidly connected, lacking buffering and adjustment capabilities. Due to slight thickness fluctuations in the rolled metal sheets, the rigid clamping structure either damages the thin metal sheets due to excessive pressure or causes the metal sheets to slip due to insufficient pressure, making it impossible to achieve uniform speed conveying. At the same time, the guiding and feeding components of some devices are not linked and rely solely on a single drive for conveying, which further exacerbates the shaking and deviation during the conveying process and affects the subsequent stamping accuracy.

[0006] Therefore, it is necessary to provide a stamping device for a multi-channel high-speed production line for easy-open lids to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a technical solution to address the problems in the prior art mentioned in the background section.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A stamping device for a multi-channel high-speed production line for easy-open lids includes a stamping device built on the production line of a transport device. The stamping device includes a processing table, on which a stamping unit is mounted in a lifting manner. An auxiliary guide component is suspended on one side of the top surface of the processing table. A straightening component for straightening metal sheets is installed directly below the auxiliary guide component. A feeding component is fixedly installed on the top surface of the processing table between the auxiliary guide component and the stamping unit.

[0010] The alignment assembly includes a second mounting bracket, a second drive motor, a bidirectional lead screw, a nut seat, an alignment platform, and a linear limiting mechanism. The second mounting bracket is fixedly mounted on the top surface of the machining table, and the second drive motor is fixedly mounted on the side wall of the second mounting bracket. One end of the bidirectional lead screw is keyed to the output shaft of the second drive motor, and the other end of the bidirectional lead screw is rotatably mounted on the machining table via a bearing seat. The side wall of the alignment platform is fixedly mounted to the nut seat, and the nut seat is threaded to both ends of the bidirectional lead screw. The alignment platform is slidably mounted on the machining table via the linear limiting mechanism.

[0011] Preferably, the alignment table includes a slide, a through groove, and guide posts. The slide has a through groove on its side wall, through which the bidirectional lead screw passes. The bottom surface of the slide is slidably mounted on the processing table via a linear limiting mechanism. The top of the slide has a notch, in which multiple guide posts are rotatably mounted.

[0012] Preferably, the top of the slide table has a horizontal strip structure, and the notch is a rectangular groove.

[0013] Preferably, the linear limiting mechanism includes a guide rail and a slide block. The guide rail is fixedly installed on the top surface of the processing table, and the slide block is fixedly installed on the bottom surface of the slide table. The slide block is slidably installed on the guide rail.

[0014] Preferably, the auxiliary guiding assembly includes a suspension, a fixed frame, a buffer mechanism, a rotating frame, a support, and an auxiliary roller. The suspension is suspended on one side of the top surface of the processing table. The fixed frame is fixedly installed at the center of the top surface of the suspension. The buffer mechanism is fixedly installed in the fixed frame. The center of the bottom surface of the suspension is fixedly installed to the support. The two ends of the rotating frame are rotatably installed on the support through fixed shafts. The auxiliary roller is rotatably installed at the bottom of the rotating frame through bearings. The top of the rotating frame is inserted into the buffer mechanism.

[0015] Preferably, the top of the rotating frame is integrally formed with a rotating plate, and the side wall of the rotating plate is provided with a sliding groove, in which the buffer mechanism is movably installed.

[0016] Preferably, the buffer mechanism includes an air spring and a washer. The air spring is fixedly installed in the fixed frame, the movable end of the air spring is inserted into the slide groove, and the washer is sleeved on the movable end of the air spring and installed by a nut thread.

[0017] Preferably, the feeding assembly includes a first drive motor, a first mounting bracket, a rotating rod, and a drive roller. The first drive motor is fixedly mounted on the side wall of the processing table via the first mounting bracket. One end of the rotating rod is keyed to the output shaft of the first drive motor, and the other end of the rotating rod is rotatably mounted on the top surface of the processing table via a bearing seat. The drive roller is fixedly mounted on the side wall of the rotating rod.

[0018] Preferably, the drive roller and the auxiliary roller are arranged in a mirror image, and the metal sheet is fed into the stamping unit from between the drive roller and the auxiliary roller under the rotation of the drive roller.

[0019] Preferably, the stamping unit includes a lifting platform, a telescopic motion device, bushings, and a sliding column. The four corners of the lifting platform are fixedly installed to the top of the sliding column, the bushings are fixedly installed on the top surface of the processing table, the sliding column is slidably installed in the bushings, and the two sides of the bottom surface of the lifting platform are fixedly installed to the drive end of the telescopic motion device. The telescopic motion device is installed inside the processing table.

[0020] A stamping mounting plate is fixedly installed on the top surface of the processing table. A lower mold is fixedly installed on the stamping mounting plate by screws. An upper mold is fixedly installed on the bottom surface of the lifting table by screws. The upper mold and the lower mold have misaligned toothed grooves on their opposite sides. The toothed grooves of the upper mold slide into the toothed grooves of the lower mold under the piston movement of the lifting table.

[0021] Technical effects and advantages of the present invention: The stamping device for a multi-channel high-speed production line of easy-open lid proposed in this invention has the following advantages compared with the prior art:

[0022] 1. This technical solution solves the problems of conveying deviation, poor adaptability and material damage in the prior art by coordinating the movement of the alignment component and the auxiliary guide component. The positive and negative threads at both ends of the bidirectional lead screw can drive the two alignment platforms to move closer or further away from the guide rail synchronously under the drive of the second drive motor. Compared with the existing fixed spacing or manual adjustment structure, it can not only quickly adapt to metal sheets of different widths, but also completely eliminate the disadvantages of low efficiency and large deviation caused by manual adjustment.

[0023] The linear limiting mechanism, through the cooperation of the guide rail and the slide, ensures that the correction table always slides parallel, further improving the accuracy of the spacing adjustment. At the same time, the tapered guide column, which is wider at the top and narrower at the bottom, can generate a continuous lateral guiding force by using the inclined surface, effectively offsetting the curling stress of the rolled metal sheet and the uneven conveying traction force. Even under high-speed conveying conditions, it can quickly correct the deviated metal sheet to the center conveying channel, forming a stable lateral constraint, preventing the metal sheet from failing to accurately enter the stamping unit due to deviation, and reducing the shearing position deviation.

[0024] 2. This technical solution solves the problems of insufficient buffering, conveying vibration, and material damage caused by the rigid connection of existing devices by using a mirror linkage structure of an air spring buffer auxiliary guide component and a feeding component. The air spring in the auxiliary guide component uses the gas compression characteristics to achieve flexible buffering, which can adaptively expand and contract according to the thickness fluctuation of the metal sheet. With the help of the gasket, the initial preload can be adjusted by the nut. This provides sufficient clamping force to prevent the metal sheet from slipping, and avoids the damage to the thin metal sheet caused by rigid clamping. At the same time, the auxiliary roller and the drive roller of the feeding component are mirrored to form a linkage clamping and conveying structure, which replaces the existing single drive mode. The rotational friction of the drive roller provides continuous and stable conveying power, effectively suppressing vibration and deviation during the conveying process, ensuring that the metal sheet enters the stamping unit at a uniform speed and accurately. This provides a pre-guarantee for the precise shearing of the misaligned grooves of the upper and lower dies, and improves the dimensional consistency and edge accuracy of the segmented metal sheet after stamping.

[0042] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0043] Please see Figures 1 to 7 The embodiments provided by the present invention are as follows:

[0044] like Figure 1 and Figure 7As shown, a stamping device for a multi-channel high-speed production line for easy-open lids includes a stamping device 1, which is built on the production line of a transport device 9. The stamping device 1 includes a processing table 11, on which a stamping unit is mounted. The stamping unit includes a lifting platform 12, a telescopic motion device 15, bushings 13, and a sliding column 14. The four corners of the lifting platform 12 are fixedly installed with the top of the sliding column 14. The bushings 13 are fixedly installed on the top surface of the processing table 11. The sliding column 14 is slidably installed in the bushings 13. The two sides of the bottom surface of the lifting platform 12 are fixedly installed with the drive end of the telescopic motion device 15. The telescopic motion device 15 is installed inside the processing table 11.

[0045] A stamping mounting plate 5 is fixedly installed on the top surface of the processing table 11. A lower mold 6 is fixedly installed on the stamping mounting plate 5 by screws. An upper mold 7 is fixedly installed on the bottom surface of the lifting table 12 by screws. A misaligned toothed groove 8 is provided on the opposite side of the upper mold 7 and the lower mold 6. The toothed groove 8 of the upper mold 7 slides into the toothed groove 8 of the lower mold 6 under the piston movement of the lifting table 12.

[0046] The telescopic motion device 15, such as a hydraulic or pneumatic cylinder, drives the lifting platform 12 to perform vertical reciprocating motion. The sliding column 14 of the lifting platform 12 slides synchronously along the bushing 13 on the top surface of the processing table 11. When the lifting platform 12 moves downward, the upper mold 7 on its bottom surface moves downward accordingly. The toothed groove 8 of the upper mold 7 slides and engages with the toothed groove 8 of the upper and lower molds 6 on the top surface of the processing table 11. When the metal sheet is between the upper and lower molds 6, the engagement action of the toothed groove 8 completes the shearing process of the metal sheet.

[0047] like Figure 3 and Figure 4 As shown, an auxiliary guide assembly 2 is suspended on one side of the top surface of the processing table 11. The auxiliary guide assembly 2 includes a suspension 21, a fixed frame 22, a buffer mechanism, a rotating frame 27, a support 28, and an auxiliary roller 29. The suspension 21 is suspended on one side of the top surface of the processing table 11. The fixed frame 22 is fixedly installed at the center of the top surface of the suspension 21. The buffer mechanism is fixedly installed in the fixed frame 22. The center of the bottom surface of the suspension 21 is fixedly installed with the support 28. The two ends of the rotating frame 27 are rotatably installed on the support 28 through fixed shafts. The auxiliary roller 29 is rotatably installed at the bottom of the rotating frame 27 through bearings. The top of the rotating frame 27 is inserted into the buffer mechanism.

[0048] The top of the rotating frame 27 is integrally formed with a rotating plate 24. The side wall of the rotating plate 24 is provided with a sliding groove 25. The buffer mechanism is movably installed in the sliding groove 25. The buffer mechanism includes an air spring 23 and a washer 26. The air spring 23 is fixedly installed in the fixed frame 22. The movable end of the air spring 23 is inserted into the sliding groove 25. The washer 26 is sleeved on the movable end of the air spring 23 and installed by a nut thread.

[0049] The auxiliary roller 29 and the drive roller 34 of the lower feeding assembly 3 are mirror images of each other. The metal sheet passes between them. When the metal sheet passes through, the auxiliary roller 29 is subjected to the upward force of the material, which drives the rotating frame 27 to rotate around the fixed axis of the support 28. The rotating plate 24 at the top of the rotating frame 27 rotates synchronously. The groove 25 of the rotating plate 24 drives the movable end of the air spring 23 to compress or extend. The air spring 23 provides a reverse buffer force through elastic deformation. The shim 26 adjusts the initial preload of the air spring 23 through the nut, constraining the conveying trajectory of the metal sheet, while adapting to the thickness fluctuation of the metal sheet and maintaining a stable clamping pressure.

[0050] A straightening assembly 4 for straightening metal sheets is installed directly below the auxiliary guide assembly 2. A feeding assembly 3 is fixedly installed on the top surface of the processing table 11 between the auxiliary guide assembly 2 and the stamping unit. The feeding assembly 3 includes a first drive motor 31, a first mounting frame 32, a rotating rod 33 and a drive roller 34. The first drive motor 31 is fixedly installed on the side wall of the processing table 11 through the first mounting frame 32. One end of the rotating rod 33 is keyed to the output shaft of the first drive motor 31. The other end of the rotating rod 33 is rotatably installed on the top surface of the processing table 11 through a bearing seat. The drive roller 34 is fixedly installed on the side wall of the rotating rod 33.

[0051] It is worth noting that the drive roller 34 and the auxiliary roller 29 are mirror images of each other. The metal sheet is fed into the stamping unit from between the drive roller 34 and the auxiliary roller 29 under the rotation of the drive roller 34.

[0052] The first drive motor 31 drives the drive roller 34 to rotate via the rotating rod 33. The drive roller 34 cooperates with the auxiliary roller 29 of the upper auxiliary guide component 2 to clamp the metal sheet. The friction of the drive roller 34 drives the metal sheet to be conveyed towards the stamping unit, providing continuous feeding power for the metal sheet. Together with the auxiliary guide component 2, it achieves stable conveying and trajectory constraint, ensuring that the metal sheet enters the stamping unit at a uniform speed and with precision.

[0053] Among them, such as Figure 5 and Figure 6 As shown, the alignment assembly 4 includes a second mounting bracket 41, a second drive motor 42, a bidirectional lead screw 47, a nut seat 46, an alignment platform 43, and a linear limiting mechanism. The second mounting bracket 41 is fixedly mounted on the top surface of the processing table 11, and the second drive motor 42 is fixedly mounted on the side wall of the second mounting bracket 41. One end of the bidirectional lead screw 47 is keyed to the output shaft of the second drive motor 42, and the other end of the bidirectional lead screw 47 is rotatably mounted on the processing table 11 through a bearing seat. The side wall of the alignment platform 43 is fixedly mounted to the nut seat 46, and the inside of the nut seat 46 is threaded to both ends of the bidirectional lead screw 47. The alignment platform 43 is slidably mounted on the processing table 11 through the linear limiting mechanism.

[0054] The alignment table 43 includes a slide table 431, a through groove 432, and guide posts 434. The slide table 431 has a through groove 432 on its side wall, through which a bidirectional lead screw 47 passes. The bottom surface of the slide table 431 is slidably mounted on the machining table 11 via a linear limiting mechanism. The top of the slide table 431 has a notch 433, in which multiple guide posts 434 are rotatably mounted.

[0055] The second drive motor 42 drives the bidirectional lead screw 47 to rotate. The two ends of the bidirectional lead screw 47 have positive and negative threads. The two nut seats 46 respectively mesh with the positive and negative thread sections of the bidirectional lead screw 47. They move closer or further away synchronously with the rotation of the lead screw. The nut seats 46 drive the straightening platform 43 to slide along the guide rail 44 of the linear limiting mechanism to realize the adjustment of the spacing of the straightening platform 43 and adapt to metal sheets of different widths.

[0056] Among them, multiple guide posts 434 are conical in shape and have a conical structure that is wider at the top and narrower at the bottom. The top of the slide table 431 has a horizontal strip structure, and the notch 433 is a rectangular groove. When the metal sheet passes between the two straightening platforms 43, the conical guide posts 434 in the notch 433 of the slide table 431 contact the edge of the material. If the material is deviated during conveying, the inclined surface of the conical guide post 434 will generate a lateral guiding force on the material, pushing the material to the middle position of the two straightening platforms 43. Thus, the guiding effect of the inclined surface is used to correct the conveying direction of the metal sheet, eliminate the deviation when the coil is unwound, and ensure that the material accurately enters the feeding assembly 3 and the stamping unit.

[0057] The linear limiting mechanism includes a guide rail 44 and a slide block 45. The guide rail 44 is fixedly installed on the top surface of the processing table 11, and the slide block 45 is fixedly installed on the bottom surface of the slide table 431. The slide block 45 is slidably installed on the guide rail 44. When the straightening table 43 slides, the slide block 45 on the bottom surface of the slide table 431 slides synchronously along the guide rail 44 on the top surface of the processing table 11, so as to avoid the straightening table 43 from lateral deviation when the spacing is adjusted or the material is straightened, to ensure the parallelism of the two straightening tables 43, and to improve the consistency of material straightening.

[0058] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
