Description

Technical Field

[0001] This utility model relates to the field of plastic riveting technology, and in particular to a riveting device based on a press. Background Technology

[0002] In modern industrial production, vacuum forming technology is widely used in the manufacture of various plastic products. Vacuum-formed parts typically need to be connected to other parts to form complete assemblies. Currently, riveting is a common connection method, usually achieved through manual riveting or thermoforming.

[0003] Manual riveting: Each riveting point is hammered manually, and the size of the rough joint is observed and the parts are moved to judge whether the riveting is qualified. This method has low input cost and no energy consumption requirement, but the production efficiency is extremely low, the labor intensity is high, and different hammering forces and angles may lead to different riveting results and may also cause deformation of the parts.

[0004] Hot melt riveting: This method involves locally heating the surfaces of plastic parts until they melt, then applying pressure to fuse them together. After cooling, a strong connection is formed. This method produces strong riveting, but the heating process consumes a lot of energy, and the cooling time is long, resulting in low production efficiency.

[0005] Therefore, in order to improve riveting efficiency, reduce labor and energy costs, and ensure the effectiveness of riveting results, a device is needed that can simultaneously rivet multiple riveting points, maintain consistent riveting angles and forces, and consume less energy. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems by providing a riveting device based on a press, which can simultaneously rivet multiple points between blister components and other components, and can ensure the consistency and repeatability of the riveting force and angle.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A riveting device based on a press includes a press, a positioning component, and a pressing component. The press includes a press slide and a press worktable. The positioning component includes a movable tray movably mounted on the press worktable. The movable tray has a fixedly mounted positioning plate and a limiting post. The positioning plate is used to fix multiple workpieces to be riveted. The pressing component includes a punch fixing plate detachably mounted on the press slide. Multiple punches are fixedly connected to the punch fixing plate, and pre-pressed sleeves are fixedly fitted on the punches. The limiting post is used to limit the downward movement distance of the punch fixing plate. In operation, the press drives the pressing component and the positioning component to close to achieve stamping and riveting of the workpieces to be riveted.

[0009] The improved design further includes a loading workbench, on which the feed side of the press can be movably mounted. The loading workbench includes a frame and a tabletop fixedly mounted on the top of the frame. A first flow bar is fixedly mounted on the tabletop. A second flow bar is movably mounted on the press workbench, and the second flow bar can be aligned with the first flow bar along the same height. The movable tray can be moved sequentially to the press workbench via the first and second flow bars to facilitate device installation, loading, and unloading.

[0010] In a further improved embodiment, the press worktable is provided with a through groove for installing a second flow strip. The two lateral ends of the second flow strip extend out of the through groove and are fixedly connected to a mounting bracket. The two ends of the mounting bracket are connected to the press via pneumatic cylinders, and the extension and retraction of the pneumatic cylinders drive the mounting bracket to rise and fall.

[0011] Furthermore, the improved design also includes a guide component, which comprises a symmetrically arranged second guide rail and a blocking block. The second guide rail and the blocking block are arranged sequentially along the feeding direction and fixedly installed on the press worktable. A first guide rail is fixedly installed on the feeding worktable. The longitudinal width of the first guide rail and the second guide rail are aligned. The first guide rail and the second guide rail can play a limiting and guiding role when the positioning component moves, ensuring that the positioning component can be accurately aligned with the pressing component when it repeatedly enters the press.

[0012] In a further improved embodiment, mounting plates are fixedly installed on both sides of the punch fixing plate. The punch fixing plate is detachably mounted on the press slide via the mounting plates. A sealing strip is installed on the upper surface of the punch fixing plate, and the upper surface of the sealing strip is flush with the upper surface of the mounting plate.

[0013] In a further improved embodiment, a guide post is fixedly installed on the movable tray, and a guide sleeve that mates with the guide post is fixedly installed on the mounting plate.

[0014] In a further improved embodiment, guide wheels are fixedly installed on the movable tray, and the guide wheels can roll in contact with the first guide rail and the second guide rail.

[0015] In a further improved design, a handle is fixedly installed on the mobile tray to facilitate manual pushing and pulling of the mobile tray.

[0016] In a further improved design, swivel casters are fixedly installed at the four bottom corners of the frame, and the swivel casters are locking swivel casters and / or free swivel casters.

[0017] In a further improved design, through holes are provided at the four corners of the upper surface of the tabletop, and blocking pin assemblies are detachably installed in the through holes to limit the lateral displacement of the moving tray.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:

[0019] 1. This utility model involves pushing the positioning component and pressing component, both in a closed state, into the press from the loading table via a guide assembly. The pressing component is then fixedly mounted on the press. Afterward, the positioning component is pulled out to the loading table for placing the workpieces to be riveted before being pushed back into the press. This riveting device has a simple design, can be installed on a press, and is suitable for large-scale industrial production.

[0020] 2. This utility model uses a press to power and drive the pressing component to move up and down, causing the pressing component and the positioning component to close and achieve stamping and riveting of the vacuum forming parts. It enables simultaneous riveting at multiple points, efficiently completing the riveting of vacuum forming parts to other components. The riveting accuracy and strength are high, the finished product quality is stable and reliable, the operation is convenient, ensuring the effectiveness of the results and greatly reducing production costs.

[0035] See Figures 1-2 The horizontal direction from left to right is defined as the feeding direction, and the horizontal direction from left to right is defined as the discharging direction, for ease of explanation. A riveting device based on a press includes a press 10, a loading table 20, a positioning component 40, a guide component 30, and a pressing component 50. During preparation, the pressing component 50 is aligned and placed on the positioning component 40 (closed state). The positioning component 40 is pushed into the press 10 from the loading table 20 via the guide component 30. Then, the pressing component 50 is separated from the positioning component 40 and fixedly assembled on the press 10. Afterward, the positioning component 40 is pulled out to the loading table 20 for placing the workpieces to be riveted (vacuum-formed parts and other parts riveted to the vacuum-formed parts). During riveting, the press 10 provides power to drive the pressing component 50 to move up and down, causing the pressing component 50 and the positioning component 40 to close, thus achieving the stamping and riveting of the vacuum-formed parts. Wherein:

[0036] See Figures 1-2The press 10 is existing technology, and is briefly described here: The press 10 includes a press slide 11 and a press worktable 12 that are controlled to move up and down by the press control system. The press worktable 12 is arranged below the press slide 11. The press worktable 12 has three through slots along the longitudinal direction and the through slots are connected in the transverse direction. A second flow strip 13 is provided in the through slot. The two ends of the second flow strip 13 extend out of the through slot and are fixedly connected to a mounting bracket 14 on the same side. Two pneumatic cylinders 15 are symmetrically arranged below the mounting bracket 14. The pneumatic cylinders 15 are mounted on the press 10 by a bracket, and the movable end of the pneumatic cylinder 15 is fixedly connected to the bottom end of the mounting bracket so that the extension and retraction of the pneumatic cylinder 15 drives the mounting bracket 14 to drive the second flow strip 13 to move up and down. When the second flow strip 13 descends, it can be retracted into the through slot so that the positioning component 40 can be placed stably on the press worktable 12.

[0037] See Figure 1 The loading workbench 20 is movably mounted on the feed side of the press 10, serving to support the positioning assembly 40 and facilitating operations around it. The loading workbench 20 includes a frame 21, a tabletop 22, two first flow rails 23, and two first guide rails 24. The frame 21 is specifically constructed from standard aluminum profiles and connecting parts welded together. The tabletop 22 is fixedly mounted on the top of the frame 21. The two first flow rails 23 are fixedly mounted on the upper surface of the tabletop 22 and arranged symmetrically in the transverse direction. When the second flow rail 13 is raised, it can be aligned with the first flow rails 23 in height. The two first guide rails 24 are fixedly mounted on the upper surface of the tabletop 22 and arranged symmetrically in the transverse direction, with the longitudinal spacing of the first guide rails 24 greater than the longitudinal spacing of the first flow rails 23. Universal casters 26 are fixedly mounted at the four corners of the bottom of the frame 21. Specifically, two of the four universal casters are free-spinning casters, and the other two are locking casters, facilitating the fixation of the loading workbench 20 and preventing displacement. Meanwhile, through holes are provided at the four corners of the upper surface of the table 22, and blocking pin assemblies 25 can be detachably installed in the through holes. When the positioning assembly 40 is placed on the loading worktable 20 to place the workpiece, it can limit the lateral displacement of the moving tray 41 and prevent it from falling off the loading worktable 20.

[0038] See Figure 3 The guide assembly 30 includes two second guide rails 31 and two blocking blocks 32. The second guide rails 31 and the blocking blocks 32 are symmetrically mounted laterally on the press worktable 12. The blocking blocks 32 are arranged behind the second guide rails 31 along the feeding direction. When the feeding worktable 20 is completely fixed on the feeding side of the press 10, the second guide rails 31 are aligned with the first guide rails 24 and can play a limiting and guiding role when the positioning assembly 40 moves.

[0039] See Figures 4-5The positioning assembly 40 includes a rectangular movable tray 41. A positioning plate 42, four limiting posts 43, four guide posts 44, four handles 45, and eight guide wheels 46 are bolted to the upper surface of the movable tray 41. The positioning plate 42 is used to fix the workpiece to be riveted. The four limiting posts 43 are symmetrically arranged in pairs at the four corners of the movable tray 41. The four guide posts 44 are symmetrically arranged in pairs beside the limiting posts 43. The eight guide wheels 46 are arranged in pairs, with each pair of guide wheels 46 positioned on both longitudinal sides of a guide post 44, and can roll in contact with the first guide rail 24 and the second guide rail 31. During preparation, the movable pallet 41 is first placed on the first flow bar 23 of the loading worktable 20. Then, the movable pallet 41 slides sequentially through the first flow bar 23 and the second flow bar 13 onto the press worktable 12. Simultaneously, the first guide rail 24 and the second guide rail 31 prevent longitudinal displacement of the movable pallet 41 and slide in cooperation with the guide wheels 46, ensuring the accurate positioning of the movable pallet 41 within the loading worktable 20 and the press 10. Four handles 45 are arranged in pairs on both sides of the movable pallet 41 at the edges, facilitating manual pushing and pulling of the movable pallet 41.

[0040] See Figures 6-8 The pressing assembly 50 includes two mounting plates 52, with multiple punch fixing plates 51 fixed between the two mounting plates 52 by bolts. The multiple punch fixing plates 51 are arranged longitudinally at intervals. During preparation, the mounting plates 52 are bolted to the lower surface of the press slide 11. A sealing strip 54 is installed on the upper end face of each punch fixing plate 51, and the upper end face of the sealing strip 54 is flush with the upper end face of the mounting plate 52. Multiple punch fixing holes are opened on each punch fixing plate 51, and punches 55 are fixedly installed in the punch fixing holes. The punches 55 are designed to correspond to the riveting points. A pre-compression sleeve 56 is fixedly sleeved on the punch 55 using a hose clamp. The pre-compression sleeve 56 can guide the punch and ensure that the punch 55 always maintains the correct direction and position during the stamping process. Corresponding to the positioning component 40, four guide sleeves 53 that cooperate with the guide post 44 are fixedly installed on the lower surface of the mounting plate 52 to ensure the accuracy of the relative position of the pressing component 50 and the positioning component 40 during the up and down movement. The limiting post 43 of the positioning component 40 is used to limit the downward movement distance of the punch fixing plate 51.

[0041] The working process of this utility model:

[0042] 1. Installation and preparation: Clean the equipment table and site. Push the loading worktable 20, which carries the closed pressing component 50 and the positioning component 40, to the feeding side of the press 10 and align it with the press worktable 12. Then, raise the second flow bar 13 of the press 10 and align it with the first flow bar 23 of the loading worktable 20 at the same height. Push the closed pressing component 50 and the positioning component 40 onto the press worktable 12 and attach the pressing component 50 to the lower surface of the press slider 11. Raise the press slide 11 so that the pressing component 50 rises and disengages from the positioning component 40. Set it as the upper stop point of the press stroke. Repeatedly raise and lower the press slide 11 to ensure that the pressing component 50 and the positioning component 40 are guided correctly and effectively. Then, install the guide component 30 on the press worktable 12, ensuring that the positioning component 40 and the guide component 30 are accurately aligned. Align the first guide rail 24 with the second guide rail 31 to ensure that the positioning component 40 can smoothly enter and exit the press 10. Finally, lock the universal casters 26 of the loading worktable 20.

[0043] II. Positioning and Placement: The positioning component 40 is pulled out onto the loading worktable 20. The blister parts to be riveted and other parts are precisely placed onto the positioning component 40. The positioning component 40, with the parts in place, is smoothly pushed from the loading worktable 20 into the press machine 10 by manual pushing through the guide component 30. The positioning component 40 stops after contacting the blocking block 32, causing the second flow bar 13 of the press machine 10 to fall and be retracted into the through groove, so that the positioning component 40 is stably placed on the press machine worktable 12.

[0044] III. Riveting Process: Start the press 10, drive the press slide 11 to move downwards, and the pressing component 50 presses down with the press slide 11. Through the guide sleeve 53 and the guide post 44 on the positioning component 40, the several punches of the pressing component 50 accurately press on the riveting points of each blister component. During this time, the pre-press sleeve 56 on the pressing component 50 will first contact the part to be riveted, ensuring that it can fit tightly with the blister component. When the pressing component 50 contacts the limiting post 43 of the positioning component 40, the pressing stops, and the riveting of the blister component by the punches 55 of the pressing component 50 is completed, and the blister component is firmly connected with other components.

[0045] IV. Finished Product Removal: After riveting is completed, the pressing component 50 returns to its original position along with the press slide 11, and the second flow bar 13 rises, pulling the positioning component 40 onto the loading worktable 20. The riveted parts are then inspected and removed, and the process waits for the next round of operations.
