Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic capacitors, in particular to a cold pressure riveting tool. Background Art

[0002] Aluminum electrolytic capacitors use an aluminum cylinder filled with liquid electrolyte as the negative electrode and a bent aluminum strip inserted into the aluminum cylinder as the positive electrode. After being treated with DC voltage, an oxide film will form on the surface of the positive electrode as a medium. When assembling the aluminum electrolytic capacitor, the lead wires must be cold-pressed and riveted after being punctured to fix the position of the flower pattern and aluminum gasket.

[0003] The utility model patent with patent application publication number CN 218826677 U discloses a cold riveting tool, including a lead bar, a through hole is opened in the center of the lead bar, a plurality of lead bar folds are arranged on the outer edge of the top of the through hole, an aluminum washer is arranged at the bottom of the lead bar, a washer protrusion is arranged at the center position of the top of the aluminum washer, the washer protrusion passes through the center position of the lead bar fold, and a riveting assembly for applying pressure to the washer protrusion is arranged on the top of the washer protrusion.

[0004] The utility model uses a sleeve to set up. During the riveting process, the bottom plane of the sleeve first presses the lead wire pattern, and then the middle rivet head presses down to ensure that the lead wire pattern is not easy to fall off. The diameter design of the rivet head of the riveting mold ring can be smoothed in real time according to the diameter of the raised part of the gasket to achieve precise riveting.

[0005] However, the above-mentioned cold riveting tool still has some shortcomings in actual use. The most obvious one is that when the first baffle moves downward under pressure, the second baffle will be driven downward by the compression spring. When the second baffle moves downward, it will simultaneously drive the sleeve to apply pressure to the lead wire flanging. Therefore, during the cold pressing process of the rivet head, the sleeve not only cannot effectively protect the lead wire flanging, but also easily causes the lead wire flanging to be excessively turned outward due to excessive pressure, thereby making it impossible to effectively fit with the protruding part of the gasket after being deformed under pressure, thereby causing the problem of loose parts after cold riveting.

[0006] Therefore, it is necessary to invent a cold riveting tool to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a cold riveting tool, which is provided with a lifting connection mechanism and a detachable limiting mechanism, so that before the cold pressing officially starts, the limiting sleeve of the detachable limiting mechanism can be used to limit the folding of multiple lead strips. Even if the deformed gasket protrusion has a slight effect on the folding of multiple lead strips, the folding of the lead strips cannot be deformed outward, thereby ensuring that the gasket protrusion and the multiple lead strips are effectively fitted together, so as to solve the problem proposed in the above background technology that during the cold pressing process of the rivet head, the sleeve not only cannot effectively protect the folding of the lead strips, but also easily causes the folding of the lead strips to be excessively turned outward due to excessive pressure, thereby making it impossible to effectively fit with the gasket protrusion after compression deformation, thereby causing the problem of loose parts after cold riveting.

[0017] Technical effects and advantages of the utility model:

[0018] The utility model is provided with a lifting connection mechanism and a detachable limiting mechanism, so that before the cold pressing officially starts, the limiting sleeve of the detachable limiting mechanism can be used to limit the plurality of lead strips.

[0027] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0030] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0031] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0032] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features.

It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0034] Figure 1 It is a schematic diagram of the overall structure of a cold riveting tool according to an embodiment of the present disclosure.

[0035] Figure 2 It is a schematic structural diagram of a cold pressing mechanism 1 and a lifting connection mechanism 2 of a cold pressing riveting tool according to an embodiment of the present disclosure.

[0036] like Figure 1-Figure 3 As shown, the cold press riveting tool disclosed in the present invention may include: a cold press mechanism 1, a lifting connection mechanism 2, a detachable limiting mechanism 3 and other components.

[0037] like Figure 2As shown, in the present disclosure, the cold pressing mechanism 1 includes a rivet head 11, a baffle 12, a guide slot 13 and a guide slider 14, wherein the baffle 12 is fixedly arranged on the top of the rivet head 11, the guide slot 13 is opened on the side of the rivet head 11, and the guide slider 14 is slidably arranged on the inner side of the guide slot 13 along the vertical direction, and the guide slider 14 is fixedly connected to the inner wall of the rotating ring 21.

[0038] Therefore, when the baffle 12 is pressed and drives the rivet head 11 to descend, the rivet head 11 gradually approaches the raised portion of the washer until it contacts the raised portion of the washer and then continues to apply pressure to the raised portion of the washer, thereby causing the raised portion to deform.

[0039] like Figure 2 As shown, in the present disclosure, the lifting connection mechanism 2 includes a rotating collar 21, an annular baffle 22 and a threaded collar 23, wherein the rotating collar 21, the annular baffle 22 and the threaded collar 23 are sequentially slidably sleeved on the outside of the rivet head 11 from top to bottom, and the annular baffle 22 is fixedly arranged between the rotating collar 21 and the threaded collar 23.

[0040] Therefore, when the detachable limiting mechanism 3 needs to be replaced to adjust the combination of the rivet head 11 and the limiting sleeve 31, the technician can rotate the limiting sleeve 31 while holding the rotating ring 21, and then more conveniently complete the disassembly and replacement of the new detachable limiting mechanism 3, so that the present device can be suitable for combinations of gasket protrusions and lead wire fringes of different specifications.

[0041] like Figure 2 As shown, in a preferred embodiment, the lifting connection mechanism 2 further includes a plurality of anti-slip ridges 24 , and the plurality of anti-slip ridges 24 are evenly and fixedly arranged on the outer side of the rotating ring 21 .

[0042] Therefore, when the user holds the rotating ring 21 , the presence of the plurality of anti-slip ridges 24 can effectively prevent the user's hand from slipping.

[0043] Figure 3 It is a schematic structural diagram of a detachable limiting mechanism 3 of a cold riveting tool according to an embodiment of the present disclosure.

[0044] like Figure 3 As shown, in the present disclosure, the detachable limiting mechanism 3 includes a limiting sleeve 31 and a counterweight ring 32, wherein the limiting sleeve 31 is sleeved on the outer bottom of the threaded ring 23 and is detachably connected to the threaded ring 23 through threads, and the counterweight ring 32 is fixedly sleeved on the outer top of the limiting sleeve 31.

[0045] Therefore, when the baffle 12 is pressed and drives the rivet head 11 to descend, the limiting sleeve 31 gradually sleeves on the outer sides of the plurality of lead wires, thereby limiting the plurality of lead wires. At this time, due to the obstruction of the lead wires, the limiting sleeve 31 no longer descends synchronously with the rivet head 11. Subsequently, as the rivet head 11 continues to descend, the limiting sleeve 31 drives the annular baffle 22 to move upward through the threaded collar 23. When the annular baffle 22 moves upward, the rotating collar 21 drives the guide slider 14 to continue to move upward inside the guide slot 13.

[0046] At this time, as the rivet head 11 continues to move downward, the bottom end of the rivet head 11 cold presses the washer protrusion, causing it to deform under pressure until its outer wall fits with the inner walls of the multiple lead line patterns. At this time, due to the obstruction of the limiting sleeve 31, even if the deformed washer protrusion slightly affects the multiple lead line patterns, the lead line patterns cannot deform outward, thereby ensuring that the washer protrusion effectively fits with the multiple lead line patterns.

[0047] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment / method or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments / methods or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0049] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present disclosure.
