Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

Therefore, the features limited by "first" and "second" can be explicitly or implicitly included at least one of the features. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed in the present application.

[0041] Limited by the structure of the riveting machine itself, the rivet groove size of the existing riveting machine is fixed, and it can only be used to press a single type of rivet. It is difficult to press rivets and difficult to take rivets during the riveting process. In addition, the traditional riveting machine has many dead angles for riveting, and can only complete the riveting of a single rivet on the horizontal plane of the workpiece, and cannot realize riveting at other different positions of the workpiece.

[0042] Reference Figures 1 to 7 The application provides an in-mold riveting assembly 10 and a riveting machine to solve the problems that only a single rivet can be riveted, a single type of rivet can be riveted, and it is difficult to rivet and difficult to take rivets.

[0043] The in-mold riveting assembly 10 is applied to the riveting machine, and the in-mold riveting assembly 10 comprises a connecting seat 100 and a plurality of movable pieces 200. The connecting seat 100 has an open limiting space 101, a plurality of first guide portions 102 are arranged around the circumferential wall of the limiting space 101, and the plurality of first guide portions 102 are arranged in a gradually expanding manner from inside to outside along the axial direction of the limiting space 101.

[0044] The plurality of movable pieces 200 are spliced with each other to form a rivet groove 201 for defining a rivet 500 to be processed. The plurality of movable pieces 200 are slidably moved into and out of the limiting space 101 along the first guide portion 102, and are used to adjust the size of the rivet groove 201 during the movement into and out of the limiting space 101.

[0045] The in-mold riveting is a high-efficiency process of directly completing riveting inside a stamping die, which can accurately install a rivet or a riveting piece on a workpiece 20. The open limiting space 101 on the connecting seat 100 provides sufficient movement range and stable positioning basis for the movable piece 200, ensuring the accuracy and stability of the riveting process. The first guide part 102 is gradually expanded from inside to outside along the axial direction of the limiting space 101, forming smooth inclined surfaces. These inclined surfaces not only play a role in stable guidance, reducing friction and wear, but also enable the movable piece 200 to smoothly slide in and out of the limiting space 101, further reducing impact, noise and vibration during the stamping process.

[0046] When the movable piece 200 enters and exits the limiting space 101, the size of the rivet groove 201 can be flexibly adjusted through the mutual cooperation between the plurality of movable pieces 200, and the rivet groove 201 suitable for rivets of different sizes is jointly constructed. Compared with the rivet groove with fixed size, the rivet is difficult to be pressed when the gap between the rivet and the rivet groove is too small, and the rivet is difficult to be pressed. The design of the present application significantly enhances the versatility and practicality of the in-mold riveting assembly 10, and effectively solves the problem of difficulty in taking the piece after riveting.

[0047] Traditional riveting machines such as sheet metal machine boxes have many dead angles in riveting, which can only realize riveting on the horizontal plane of the workpiece. Compared with traditional sheet metal machine box riveting or other fixed riveting structure on the riveting machine, the in-mold riveting assembly 10 of the present application is a modular design structure with higher flexibility and adaptability, and the combination with the riveting machine is more flexible. It can process different types of rivet products, and has lower requirements for the use environment. It can rivet multiple rivets at different positions of the workpiece 20, such as the horizontal plane of the workpiece and the bending position of the workpiece, and is suitable for riveting of various types and sizes of parts, greatly improving the production efficiency.

[0048] In actual application, only the rivet to be processed 500 is placed in the rivet groove 201 accurately constructed by the movable piece 200, and the rivet can be easily riveted by the pressure of the riveting machine. During the whole process, the in-mold riveting assembly 10 not only ensures the accuracy and stability of the riveting, but also greatly improves the production efficiency, providing strong support for industrial automation and batch production.

[0049] Reference Figures 1 to 6 In an embodiment, the peripheral wall of at least part of the plurality of movable pieces 200 is provided with a second guide part 202, and the second guide part 202 and the first guide part 102 are slidingly matched.

[0050] It can be understood that one or more of the plurality of movable members 200 is provided with a second guide part 202, and the number and position of the second guide part 202 correspond to the first guide part 102 provided in the limiting space 101. By setting the second guide part 202 and the first guide part 102 to be slidingly matched, the movable member 200 can stably slide along the predetermined track when entering or leaving the limiting space 101, effectively avoiding position deviation, thereby improving the stability of the rivet control.

[0051] With reference to Figures 2 to 6 Further, one of the first guide part 102 and the second guide part 202 is a guide groove, and the other is a guide protrusion.

[0052] It can be understood that when the first guide part 102 is configured as a guide groove, the corresponding second guide part 202 is set as a guide protrusion that is slidingly matched with the guide groove; conversely, when the first guide part 102 is configured as a guide protrusion, the corresponding second guide part 202 is set as a guide groove that is slidingly matched with the guide protrusion. The configuration of the first guide part 102 and the second guide part 202 is corresponding, that is, all the first guide parts 102 are guide grooves (or guide protrusions), and all the second guide parts 202 are corresponding guide protrusions (or guide grooves); or, part of the first guide parts 102 are set as guide grooves, and the rest are set as guide protrusions, and the corresponding second guide parts 202 are set as guide grooves and guide protrusions respectively. The specific configuration mode is determined according to actual needs, and will not be described here.

[0053] With this modular design of setting one as a guide groove and the other as a guide protrusion, stable limiting is achieved without affecting the sliding in and out of the movable member 200. In addition, this design makes maintenance and replacement more convenient: when the connecting seat 100 or the movable member 200 is worn or damaged, only the damaged part needs to be replaced, without the need to replace the entire in-mold riveting assembly 10, effectively reducing maintenance costs.

[0054] The plurality of movable members 200 includes two, three or other multiple movable members 200, and the movable members are defined as a first movable member 210, a second movable member 220, a third movable member, etc.

[0055] With reference to Figures 2 to 6 In an embodiment, the plurality of movable members 200 includes a first movable member 210 and a second movable member 220 arranged oppositely, the first movable member 210 is provided with a first groove segment 2101 on the side close to the second movable member 220, the second movable member 220 is provided with a second groove segment 2201 on the side close to the first movable member 210, and the first groove segment 2101 and the second groove segment 2201 are combined with each other to form a rivet groove 201.

[0056] The shapes and sizes of the first groove segment 2101 and the second groove segment 2201 are designed to correspond to each other to ensure that the rivet groove 201 formed after splicing has precise size and shape. This design allows the position and size of the groove segments to be adjusted according to the specifications of the rivet, enabling the in-mold riveting assembly 10 to be flexibly adapted to rivets of different specifications, thereby expanding its scope of application and flexibility.

[0057] When the shapes and sizes of the first groove segment 2101 and the second groove segment 2201 are the same, the size and shape of the groove segments can be determined according to the type of the rivet 500 to be processed. For example, the first groove segment 2101 and the second groove segment 2201 are designed to have a semicircular cross-section. When the first movable piece 210 and the second movable piece 220 are moved into the limiting space 101, the first groove segment 2101 of the first movable piece 210 and the second groove segment 2201 of the second movable piece 220 will cooperate with each other to form a complete rivet groove 201.

[0058] When the shapes and sizes of the first groove segment 2101 and the second groove segment 2201 are different, the opening of one of the groove segments can be determined according to the connecting portion, and the opening of the other groove segment is designed accordingly. For example, at least part of the first groove segment 2101 can be designed to protrude out of the first movable piece 210 through its opening, or at least part of the second groove segment 2201 can be designed to protrude out of the second movable piece 220 through its opening, to achieve clamping adaptation. In this case, the groove segments can be designed to have an arc-shaped cross-section, with the first groove segment 2101 being larger in size than the second groove segment 2201, so that the first groove segment 2101 is embedded in the second groove segment 2201 to form the rivet groove 201, or the second groove segment 2201 is larger in size than the first groove segment 2101, so that the second groove segment 2201 is embedded in the first groove segment 2101 to form the rivet groove 201.

[0059] In addition to arranging the plurality of movable pieces 200 as the first movable piece 210 and the second movable piece 220 arranged opposite to each other, the plurality of movable pieces 200 can also be spliced together along their circumferences to form the rivet groove 201. The number of movable pieces 200 can be three, four, or other numbers. Each movable piece 200 is provided with groove segments on the side close to each other, which will cooperate with each other after splicing to form a complete rivet groove 201. Similarly, the cross-sectional shape of the groove segments, such as an arc shape or other shapes, can be determined according to the type of the rivet 500 to be processed, and the corresponding arrangements are made with reference to the previous embodiments. Details are not repeated here.

[0060] With reference to Figures 2 to 6 In an embodiment, the side of the first movable piece 210 and the second movable piece 220 away from each other is provided with a second guide portion 202, which is in sliding adaptation with the first guide portion 102.

[0061] The second guide part 202 is arranged on the side away from each other of the first movable part 210 and the second movable part 220, and is in sliding fit with the corresponding first guide part 102. This design is mainly used to ensure that the movable part 200 can stably slide along the predetermined track when entering and leaving the limiting space 101, effectively avoiding position deviation, thereby significantly improving the stability and precision of the rivet control. In addition, this layout not only enhances the stability of the overall structure, but also better adapts to the movement requirements of the movable part 200, providing flexible guiding support. At the same time, through reasonable layout design, the mutual interference problem that may occur during the process of the movable part 200 entering the limiting space 101 is avoided.

[0062] In addition to the aforementioned second guide part 202 arranged on the side away from each other of the first movable part 210 and the second movable part 220, the second guide part 202 can also be arranged on any other side of the first movable part 210 and the second movable part 220. The specific arrangement is not limited here.

[0063] Referring to Figures 2 to 5 As an example, along the axial direction of the limiting space 101, the distance between the plurality of movable parts 200 gradually increases from the inside to the outside.

[0064] It can be understood that the plurality of movable parts 200 can slide along the first guide part 102 to enter and leave the limiting space 101, so as to flexibly adjust the size of the rivet groove 201 during the process. When moving out of the limiting space 101, the distance between the movable parts 200 gradually increases, facilitating the placement of different sizes of the to-be-processed rivet 500; when moving into the limiting space 101, the distance between the plurality of movable parts 200 gradually decreases, limiting the to-be-processed rivet 500, avoiding position deviation of the to-be-processed rivet 500, and ensuring riveting precision and stability. This design not only improves the flexibility and production efficiency of processing, reduces the mold adjustment and replacement process, but also effectively reduces the impact of the movable part 200 when entering and leaving the limiting space 101, and solves the problem of difficult rivet removal after riveting.

[0065] On the basis of the foregoing embodiment, the plurality of first guide parts 102 arranged along the circumferential wall of the limiting space 101 are arranged in a gradually expanding manner along the axial direction of the limiting space 101 from the inside to the outside, and the second guide part 202 is arranged on any side of the movable part 200, so that when moving out of the limiting space 101, the distance between the movable parts 200 gradually increases.

[0066] Referring to Figure 6 As another example, the radial width of the limiting space 101 gradually increases from the inside to the outside along the axial direction.

[0067] It can be understood that the plurality of movable members 200 are slidably in and out of the limiting space 101 along the first guide part 102, and they cooperate with each other to adjust the size of the rivet groove 201 during this process. The movable structure formed by these movable members 200 is perfectly adapted to the limiting space 101 in terms of size, shape, etc. The radial width of the limiting space 101 gradually increases from inside to outside along its axial direction, forming a conical structure with narrow inside and wide outside. Correspondingly, the plurality of movable members 200 also present an adaptive conical structure with narrow inside and wide outside when they are combined with each other. This design ensures that the movable members 200 can experience a smooth transition when they are in and out of the limiting space 101, and the progressive guiding mechanism helps the stable movement of the movable members 200, thereby effectively reducing friction and wear.

[0068] On the basis of the foregoing embodiments, the plurality of first guide parts 102 can be specifically provided as two or other even numbers, and the plurality of first guide parts 102 are oppositely arranged on the left and right sides (and / or front and back sides) of the circumferential wall of the limiting space 101, and the second guide part 202 arranged on the plurality of movable members 200 is correspondingly arranged. The plurality of first guide parts 102 are gradually expanded from inside to outside along the axial direction of the limiting space 101, that is, the size of the plurality of first guide parts 102 gradually increases from inside to outside along the axial direction of the limiting space 101 and is wedge-shaped, so that the radial width of the limiting space 101 gradually increases from inside to outside along its axial direction.

[0069] Referring to Figures 2 to 6 In an embodiment, the connecting seat 100 is provided with an elastic member 300 corresponding to the position of the limiting space 101, and the elastic member 300 is arranged relative to the plurality of movable members 200, for guiding the plurality of movable members 200 to move in and out of the limiting space 101 along the first guide part 102.

[0070] The elastic member 300 can be a spring, an elastic pressing piece, or an elastic connecting piece. Taking the case where the elastic member 300 is a spring, one end of the elastic member 300 is connected with the connecting seat 100, and the other end is connected with the movable member 200. The elastic member 300 mainly plays a role of positioning and guiding: when the movable member 200 moves into the limiting space 101, the elastic member 300 is compressed, which can ensure the stable movement of the movable member 200 along the predetermined track of the first guide part 102, avoid the position deviation of the movable member 200 during movement, and help to maintain the stability of the movable member 200 in and out; when the movable member 200 needs to move out of the limiting space 101, the elastic reset of the elastic member 300 can promote the movable member 200 to move outwards. The elastic member 300 can keep the stable position of the movable member 200 in the limiting space 101 to a certain extent, prevent unnecessary movement of the movable member 200 due to external factors, and further ensure the reliability during riveting.

[0071] Referring to Figures 2 to 6In an embodiment, the connecting seat 100 comprises a first connecting seat 110 and a second connecting seat 120 connected as a whole, the limiting space 101 is arranged in the middle of the first connecting seat 110, and the side of the second connecting seat 120 close to the first connecting seat 110 is provided with a limiting groove 121 for mounting the elastic member 300. The limiting space 101 is arranged in the middle of the first connecting seat 110, and is determined as inside close to the second connecting seat 120 and as outside away from the second connecting seat 120. The limiting space 101 is open, and the opening of the limiting space 101 is located at the side of the first connecting seat 110 away from the second connecting seat 120. The limiting groove 121 of the elastic member 300 is arranged at the side of the second connecting seat 120 close to the first connecting seat 110, which helps to compact the overall structure and improve the space utilization. By arranging the limiting groove 121 close to the connecting surface of the connecting seat 100 to mount the elastic member 300, the assembly process can be simplified, and the reliability of the connection can be optimized. The elastic member 300 not only provides additional support and buffering effect, but also effectively reduces the loosening of the connection caused by external force. In addition, this arrangement also ensures that the elastic member 300 can stably guide the movable member 200 to enter and exit the limiting space 101 along the first guide portion 102, thereby improving the stability of the movement of the movable member 200 and the positioning accuracy.

[0072] With reference to Figures 1 to 7 In an embodiment, the in-mold riveting assembly 10 further comprises a press riveting upper die 400 arranged corresponding to the position of the rivet groove 201, for transmitting the pressure of the press riveting machine to the to-be-processed rivet 500 in the rivet groove 201.

[0073] The design of the press riveting upper die 400 ensures that the pressure of the press riveting machine can be accurately and stably transmitted to the to-be-processed rivet 500 in the rivet groove 201. By accurately controlling the size, direction and action time of the pressure, the press riveting upper die 400 can ensure that the to-be-processed rivet 500 receives uniform and sufficient pressure during the riveting process, thereby effectively avoiding problems such as poor riveting, riveting failure and rivet damage, and ensuring the quality and reliability of the riveting connection.

[0074] With reference to Figures 1 to 7 The specific implementation process of the present application is as follows:

[0075] The connecting seat 100 has an open limiting space 101, and the peripheral wall of the limiting space 101 is provided with a plurality of first guide portions 102 arranged in a gradually expanding manner from inside to outside along the axial direction of the limiting space 101.

[0076] The plurality of movable pieces 200 are combined with each other to form the rivet groove 201 for defining the rivet 500 to be processed. Along the axial direction of the limiting space 101, the plurality of movable pieces 200 are slidably moved in and out of the limiting space 101 along the first guide part 102, and the distance between the plurality of movable pieces 200 gradually increases from inside to outside. The size of the rivet groove 201 is adjusted correspondingly during the movement in and out of the limiting space 101.

[0077] Among the plurality of movable pieces 200, the first movable piece 210 and the second movable piece 220 are oppositely arranged. The first movable piece 210 is provided with a first groove segment 2101 on the side close to the second movable piece 220, and the second movable piece 220 is provided with a second groove segment 2201 on the side close to the first movable piece 210. The first groove segment 2101 and the second groove segment 2201 are combined with each other to form the rivet groove 201.

[0078] The side of the first movable piece 210 and the second movable piece 220 away from each other is provided with a second guide part 202, which is slidably matched with the first guide part 102. One of the first guide part 102 and the second guide part 202 is a guide groove, and the other is a guide protrusion.

[0079] The connecting seat 100 is provided with an elastic piece 300 at the position corresponding to the limiting space 101. The elastic piece 300 is arranged relative to the plurality of movable pieces 200. When moving out of the limiting space 101, the first movable piece 210 and the second movable piece 220 are driven to move outwardly out of the limiting space 101 by the elastic action of the elastic piece 300, and the distance between the first movable piece 210 and the second movable piece 220 gradually increases, which facilitates the placement of the rivet 500 to be processed with different sizes. When moving into the limiting space 101, the elastic piece 300 is compressed to ensure the stable movement of the movable piece 200 along the predetermined track of the first guide part 102, and the distance between the first movable piece 210 and the second movable piece 220 gradually decreases, which limits the rivet 500 to be processed, avoids the position deviation of the rivet 500 to be processed, and ensures the riveting precision and stability.

[0080] During the press riveting, the press riveting upper die 400 is arranged at the position corresponding to the rivet groove 201, and is used to transmit the pressure of the press riveting machine to the rivet 500 to be processed in the rivet groove 201.

[0081] The application also provides a press riveting machine, which comprises the in-die riveting assembly 10. The specific structure of the in-die riveting assembly 10 is referred to the above-mentioned embodiments. Since the press riveting machine adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0082] The above merely describes exemplary embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made based on the technical concept of the present application, using the content of the present application specification and drawings, is included in the patent protection scope of the present application.
