[0040] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.
[0041] Example
[0042] This embodiment provides a hollow rivet structure installation mold, including a first mold 100 and a second mold 200, please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of a first mold 100. Figure 2 FIG. 2 is a schematic structural diagram of the second mold 200 .
[0043] The first mold 100 is used to connect with the tool body 11 of the rivet pulling tool, and is also used to locate the bottom end of the cylindrical body 21 of the hollow rivet structure. The second mold 200 is used to connect with the telescopic rod 12 of the rivet pulling tool, and is used to squeeze the top of the cylindrical body 21 under the pulling of the telescopic rod 12, so that the top edge of the cylindrical body 21 is buckled with the washer 22, thereby completing the installation of the button body. In this embodiment, the press molding of the eyelet button is taken as an example to introduce the hollow rivet structure installation mold.
[0044] It is understandable that the rivet pulling tool can be selected according to the actual application conditions. In this embodiment, the rivet pulling tool is a rivet nut gun, and its power type is not limited, and can be manual, electric, or pneumatic.
[0045] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a cross-sectional view of a first mold 100. Figure 4 A cross-sectional view of the second mold 200 is shown.
[0046] The first die 100 is provided with a make way channel 110 for the telescopic rod 12 of the riveting tool to pass through, and the second die 200 has a connecting portion for the telescopic rod 12 to connect. When the connecting portion is connected to the telescopic rod 12, the telescopic rod 12 retracts relative to the tool body 11, driving the second die 200 to move closer to the first die 100, thereby squeezing the cylindrical body 21 to deform and complete the installation.
[0047] Specifically, the first mold 100 in this embodiment includes a mounting seat 120 and a support tube 130. The mounting seat 120 is used to connect to the tool body 11. One end of the support tube 130 is connected to the mounting seat 120, and the other end is used to be inserted into the bottom end of the cylindrical body 21. The inner wall of the support tube 130 defines a clearance channel 110.
[0048] It is understandable that after the support tube 130 is inserted into the bottom end of the cylindrical body 21 , the mounting seat 120 at least provides axial support to the bottom end of the cylindrical body 21 , and the support tube 130 provides radial limitation to the cylindrical body 21 , thereby achieving positioning of the cylindrical body 21 .
[0049] Specifically, in this embodiment, the mounting seat 120 has a supporting wall surface 122 , and the supporting wall surface 122 is disposed around the supporting tube 130 to support the bottom end of the cylindrical body 21 .
[0050] It should be noted that if the bottom end of the cylindrical body 21 of the eyelet button used has an outward-turned flange, the supporting wall 122 can be a flat structure, such as Figure 3 As shown; if the bottom end of the applied cylindrical body 21 also needs to be flanging to form a flange during the extrusion process, the abutting wall 122 can be a curved surface structure that guides the flanging of the bottom end of the cylindrical body 21.
[0051] In this state, the telescopic path of the telescopic rod 12 of the riveting tool is in the clearance channel 110, and the end of the support tube 130 away from the mounting seat 120 can be extended or retracted. In actual application, the end of the support tube 130 away from the mounting seat 120 is inserted into the bottom end of the cylindrical body 21, and after the telescopic rod 12 is driven by the tool body 11 to extend out of the top of the support tube 130 and the cylindrical body 21 in sequence, the end of the telescopic rod 12 away from the mounting seat 120 is connected to the connecting part of the second mold 200.
[0052] In this embodiment, the mounting seat 120 is provided with a first threaded hole 121 . The first threaded hole 121 is coaxially arranged with and communicated with the clearance channel 110 . The first threaded hole 121 is threadably matched with the tool body 11 .
[0053] In fact, a nut guide nozzle is installed on the tool body 11 of the rivet nut gun, and the telescopic rod 12 extends or retracts the nut guide nozzle under the drive of the tool body 11. In actual application, the nut guide nozzle is replaced with the first mold 100, that is, after the nut guide nozzle on the tool body 11 is removed, the first threaded hole 121 of the mounting seat 120 is threadedly matched with the installation position of the nut guide nozzle and tightened.
[0054] After the connection between the mounting seat 120 and the tool body 11 is completed, the telescopic rod 12 is driven by the tool body 11 to reciprocate linearly in the support tube 130 , that is, to reciprocate linearly along the clearance channel 110 .
[0055] It should be noted that, in addition to the threaded connection provided in this embodiment, for different types of riveting tools, the mounting seat 120 can establish different types of connections with the tool body 11. For example, in another embodiment, the mounting seat 120 can also be snap-fitted with the tool body 11, or welded.
[0056] In view of the fact that the telescopic rod 12 of the rivet nut gun has an external thread, in this embodiment, the connecting portion is a second threaded hole 230 opened on the surface of the second mold 200, and the second threaded hole 230 is threadedly connected to the telescopic rod 12. In actual application, after the telescopic rod 12 extends out of the support tube 130 and the cylindrical body 21 in sequence, the second threaded hole 230 is threadedly matched with the telescopic rod 12 and tightened.
[0057] Similarly, in other embodiments, the telescopic rod 12 of the riveting tool may also be connected to the second mold 200 in other ways besides threaded fitting, such as snap fitting, plug-in, welding, etc.
[0058] In order to guide the top flange of the cylindrical body 21, in this embodiment, a frustum 220 is convexly provided on the surface of the second mold 200, the second threaded hole 230 is opened on the top surface of the frustum 220 and is coaxially arranged with the frustum 220, and a supporting groove 210 is also arranged on the second mold 200 around the bottom end of the frustum 220.
[0059] It is understandable that the radius of the truncated cone 220 increases from the top to the bottom. In practical applications, the diameter of the top of the truncated cone 220 is smaller than the inner diameter of the cylindrical body 21 used, and the diameter of the bottom of the truncated cone 220 is larger than the inner diameter of the cylindrical body 21.
[0060] When the telescopic rod 12 pulls the second mold 200 to move closer to the first mold 100, the top of the truncated cone 220 first inserts into the top of the cylindrical body 21 and gradually goes deeper. During the process of going deeper, the top of the cylindrical body 21 gradually expands under the guidance and abutment of the outer surface of the truncated cone 220. As the truncated cone 220 continues to go deeper, the top of the cylindrical body 21 is embedded in the abutment groove 210 and radially turns outward under the guidance of the abutment groove 210.
[0061] In order to provide an ideal guide for the flanging of the cylindrical body 21, in this embodiment, the cross section of the abutting groove 210 may be semicircular. In addition, in order to ensure a smooth flanging process, the inner groove wall of the abutting groove 210 is connected to the outer wall of the bottom end of the truncated cone 220 and smoothly transitions.
[0062] Please refer to Figure 5 , Figure 5 Shown is a schematic structural diagram of the hollow rivet structure installation mold provided in this embodiment in actual application.
[0063] When the eyelet is actually installed, firstly, the top of the cylindrical body 21 is passed through the part to be installed 30, and a hole can be pre-opened on the part to be installed 30, and then the washer 22 is sleeved on the outer wall of the cylindrical body 21 from the top of the cylindrical body 21. Then, the mounting seat 120 of the first mold 100 is screwed on the installation position of the original nut guide nozzle on the rivet nut gun, and then the support cylinder 130 of the first mold 100 is inserted into the bottom end of the cylindrical body 21 to achieve the positioning of the cylindrical body 21.
[0064] Then, the telescopic rod 12 of the riveting tool is driven to extend until it extends from the top of the cylindrical body 21, and then the second threaded hole 230 on the second die 200 is threadedly engaged with the end of the telescopic rod 12. Finally, the telescopic rod 12 is driven to retract by the riveting tool, driving the second die 200 to gradually move closer to the first die 100, and in this process, the top flange of the cylindrical body 21 is squeezed to realize the buckling and self-fixing of the gasket 22.
[0065] It should be noted that the part to be installed 30 in this embodiment can be fabric, non-woven fabric, leather, plate material, etc.
[0066] It can be seen that the hollow rivet structure installation mold provided in this embodiment is used in conjunction with a rivet pulling tool. The rivet pulling tool can be hand-held, so that the first mold 100 does not need support in a fixed position and a fixed direction, and also avoids the problem of space limitation caused by the carrier and support frame structure of the existing pressing device.
[0067] In summary, the hollow rivet structure installation mold provided by the present invention can be applied to riveting tools to achieve pultrusion forming of eyelets without fixed support points, is not restricted by space, and has a wider range of application scenarios.
[0068] In addition, the present embodiment further provides an eyelet installation device, which includes a rivet pulling tool and the aforementioned hollow rivet structure installation mold, the rivet pulling tool includes a tool body 11 and a telescopic rod 12 arranged on the tool body 11, the first mold 100 is installed on the tool body 11, the telescopic rod 12 is used to make a linear reciprocating motion along the makeshift channel 110 under the drive of the tool body 11, and the connecting part of the second mold 200 is selectively connected to the telescopic rod 12.
[0069] It should be noted that the riveting tool can be selected according to the actual application conditions and is not limited to the aforementioned rivet nut gun. Correspondingly, the connection mode between the first mold 100 and the tool body 11 and the connection mode between the telescopic rod 12 and the second mold 200 can also be adaptively adjusted and is not limited to the aforementioned threaded fit.
[0070] Benefiting from the beneficial effects of the hollow rivet structure installation mold, the eyelet installation device provided in this embodiment can pultrude the eyelet without a fixed support position and a fixed support direction, is not restricted by space, and has a wider range of application scenarios.
[0071] In addition, this embodiment also provides a method for installing an eyelet, which is applied to the aforementioned hollow rivet structure installation mold. Figure 6 , Figure 6 The figure shows a flowchart of the eyelet installation method, which may include:
[0072] Step S101 , passing the top end of the cylindrical body 21 through the to-be-installed component 30 , and sleeve-mounting a gasket 22 on the outer wall of the portion of the cylindrical body 21 passing through the to-be-installed component 30 .
[0073] Step S102 , installing the first die 100 on the tool body 11 of the riveting tool, and positioning the bottom end of the cylindrical body 21 through the first die 100 .
[0074] In this embodiment, the mounting base 120 of the first mold 100 is screwed onto the mounting position of the original nut guide nozzle on the rivet nut gun, and then the support tube 130 of the first mold 100 is inserted into the bottom end of the cylindrical body 21 to achieve positioning of the cylindrical body 21.
[0075] Step S103 , when the telescopic rod 12 of the riveting tool is extended out of the clearance channel 110 , the connecting portion of the second mold 200 is connected to the telescopic rod 12 .
[0076] In this embodiment, the telescopic rod 12 driving the riveting tool is extended until it extends out from the top of the cylindrical body 21 , and then threadedly engages with the end of the telescopic rod 12 through the second threaded hole 230 on the second mold 200 .
[0077] Step S104 , the telescopic rod 12 is driven to retract by the riveting tool, so as to drive the second die 200 to extrude the top flange of the cylindrical body 21 to the buckling washer 22 .
[0078] The telescopic rod 12 is driven to retract by the riveting tool, driving the second die 200 to gradually move closer to the first die 100. During this process, the top flange of the cylindrical body 21 is squeezed to achieve self-fixation of the gasket 22.
[0079] The eyelet installation method provided in this embodiment can pultrude the eyelet without a fixed support position and a fixed support direction, is not limited by space, and has a wider range of application scenarios.
