Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and in particular to a riveting mold. Background Technology

[0002] TOX riveting is a riveting process that uses a riveting punch to apply high pressure to metal sheets, utilizing the plastic deformation of the material to form an interlocking inlay structure. Specifically, the riveting punch presses the upper sheet into the forming cavity, and the lower sheet undergoes plastic flow under pressure, forming a dotted connection similar to a dovetail-shaped inlay structure, thus completing the riveting.

[0003] In the existing technology, after riveting is completed, the sheet metal extruded into the forming cavity needs to be removed, and the riveting punch inserted into the forming cavity also needs to be removed. That is, the riveting punch and the forming cavity need to slide in both directions for material removal. In order to ensure smooth material removal, the travel of the riveting punch and the forming cavity needs to be set to be relatively long. This increases the space occupied by the overall structure and increases the mold cost. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a riveting mold that reduces the space occupied by the overall mechanism, thereby lowering the mold cost.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects:

[0006] This utility model provides a riveting mold, including:

[0007] An upper mold base includes an upper clamping plate and a push block, the push block being connected below the upper clamping plate; and

[0008] The lower die base is located below the push block. The lower die base includes a lower template, a sliding seat, a stop block, a punching and riveting assembly, and a forming assembly. The sliding seat is slidably connected to the lower template, the stop block is connected to the sliding seat, the punching and riveting assembly is slidably connected to the sliding seat and elastically connected to the stop block, and the forming assembly is connected to the sliding seat and located on the side of the punching and riveting assembly opposite to the stop block.

[0009] The distance between the stop block and the push block is less than the distance between the riveting assembly and the push block, and a push station is formed between the stop block and the riveting assembly. When the upper mold base and the lower mold base are closed, the push block pushes the stop block and the riveting assembly in sequence to complete the riveting of the forming assembly and the riveting assembly. When the upper mold base and the lower mold base are separated, the push block moves away from the riveting assembly and the stop block in sequence to complete the reset.

[0010] In some implementations, the riveting assembly includes a side push slider, a riveting punch, and a first elastic member. The side push slider is slidably connected to the sliding seat and elastically connected to the stop block. The riveting punch is connected to the side push slider and is disposed toward the forming assembly. The end of the riveting punch away from the side push slider has an abutment portion. The first elastic member is sleeved on the riveting punch and its opposite ends abut against the side push slider and the abutment portion, respectively.

[0011] In this implementation, the side push slider drives the riveting punch to move toward the product to be riveted. During riveting, the first elastic element is compressed so that the riveting punch enters the forming component. As the mold opens, the push block exits the push position, the side push slider moves toward the stop block, and the first elastic element springs open so that the riveting punch disengages from the product that has been riveted, thereby achieving stripping.

[0012] In some implementations, the forming component includes a forming block and a stripping elastic member. The forming block has a forming cavity on the side facing the riveting component, and the stripping elastic member is elastically connected to the forming block and is positioned towards the riveting component.

[0013] In this implementation, during riveting, the product enters the forming cavity under the pressure of the riveting punch, the stripping elastic element is compressed, and the upper and lower plates are deformed by stamping to form an interlocking inlay structure, thereby completing the riveting; during stripping, the stripping elastic element springs open so that the riveted product is removed from the forming cavity.

[0014] In some implementations, the push block has an inclined first guide surface on the side near the stop block, and the stop block has a second guide surface that cooperates with the first guide surface to allow the push block to enter the push position.

[0015] In some implementations, the push block has an inclined third guide surface on the side near the riveting assembly, and the riveting assembly has a fourth guide surface that cooperates with the third guide surface to allow the push block to enter the push station.

[0016] In some implementations, a second elastic element is provided between the riveting assembly and the stop block.

[0017] In this implementation, the riveting assembly and the stop are elastically connected by a second elastic element. When the push block exits the push position, the riveting assembly and the stop move closer to each other under the elastic action of the second elastic element, thereby achieving a reset and facilitating the cyclic riveting operation.

[0018] In some implementations, the lower mold base further includes a fixing block and a third elastic element. The fixing block is connected to the lower mold plate, and the opposite ends of the third elastic element are respectively connected to the fixing block and the sliding seat.

[0019] In some implementations, the lower die holder further includes a limiting block connected to the lower die plate and located between the punching and riveting assembly and the stop block.

[0020] In some implementations, the riveting die further includes a drive mechanism, with two upper die bases and two lower die bases, the two upper die bases being symmetrically arranged, and the drive mechanism being driven and connected to the two upper die bases.

[0021] In some implementations, the riveting mold further includes a guide post, which is telescopically connected between the upper clamping plate and the lower template, and the driving mechanism is located between the two upper clamping plates.

[0022] In summary, this utility model has at least the following advantages:

[0023] The riveting mold provided by this utility model places the product to be riveted between the forming component and the riveting component. The upper clamping plate, close to the lower mold base, drives the pusher block to enter the pusher station, sequentially pushing the stop block and the riveting component. The stop block, through the sliding seat, drives the forming component towards the product to be riveted, and the riveting component moves along the sliding seat towards the product to be riveted. During the process of pushing the riveting component, the pusher block applies pressure to the product to be riveted, pressing the product into the forming component, thereby completing the riveting. When the mold opens, the riveting component and the stop block elastically move closer to each other under the action of elasticity, moving away from the riveted product, thereby achieving material removal. This arrangement reduces the space occupied by the overall mechanism, thereby reducing the mold cost. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see the appendix Figure 1 ~Appendix Figure 4 The riveting mold of this utility model includes an upper mold base 10 and a lower mold base 20.

[0039] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the upper mold base 10 and the lower mold base 20 in this embodiment of the invention. Figure 2The diagram illustrates the specific structure of the lower mold base 20 in this embodiment of the present invention. Specifically, the upper mold base 10 includes an upper clamping plate 11 and a push block 12, with the push block 12 connected below the upper clamping plate 11; the lower mold base 20 is located below the push block 12, and includes a lower template 21, a sliding seat 22, a stop block 23, a riveting assembly 24, and a forming assembly 25. The sliding seat 22 is slidably connected to the lower template 21, the stop block 23 is connected to the sliding seat 22, the riveting assembly 24 is slidably connected to the sliding seat 22 and elastically connected to the stop block 23, and the forming assembly 25 is connected to the sliding seat 22 and located on the side of the riveting assembly 24 facing away from the stop block 23. The distance between the stop block 23 and the push block 12 is less than the distance between the riveting assembly 24 and the push block 12, and a push station 26 is formed between the stop block 23 and the riveting assembly 24. When the upper mold base 10 and the lower mold base 20 are closed, the push block 12 pushes the stop block 23 and the riveting assembly 24 in sequence so that the forming assembly 25 and the riveting assembly 24 can be riveted together. When the upper mold base 10 and the lower mold base 20 are separated, the push block 12 moves away from the riveting assembly 24 and the stop block 23 in sequence to complete the reset.

[0040] In this embodiment, when riveting is performed, the product to be riveted is located between the forming component 25 and the riveting component 24. The upper mold base 10 and the lower mold base 20 are closed, and the upper clamping plate 11 moves towards the lower template 21, thereby driving the push block 12 into the push station 26. Since the distance between the stop block 23 and the push block 12 is less than the distance between the riveting component 24 and the push block 12, the push block 12 first pushes the stop block 23, so that the stop block 23 drives the forming component 25 to move towards the product to be riveted through the sliding seat 22. As the push block 12 continues to push, the push block 12 pushes the riveting component 24, so that the riveting component 24 slides along the sliding seat 22 and moves towards the product to be riveted. During the process of the push component pushing the riveting component 24, the riveting component 24 applies pressure to the product to be riveted, so as to press the product to be riveted into the forming component 25. The upper plate and the lower plate of the product to be riveted are formed into an interlocking inlay structure after being stamped and deformed, thereby completing the riveting.

[0041] Then, the upper mold base 10 and the lower mold base 20 open, and the upper clamping plate 11 moves away from the lower mold base 20, thereby driving the push block 12 to move away from the riveting assembly 24 and the stop block 23 in sequence, thus exiting the push station 26. Since the riveting assembly 24 and the stop block 23 are elastically connected, when the push block 12 exits the push station 26, the riveting assembly 24 and the stop block 23 elastically move closer to each other under the action of elasticity, so that the riveting assembly 24 and the forming assembly 25 move away from the product that has been riveted, thereby realizing material removal. Specifically, when the stop block 23 approaches the riveting assembly 24, it drives the forming assembly 25 to move through the sliding seat 22, so that the forming assembly 25 moves away from the product that has been riveted. The riveting assembly 24 moves closer to the stop block 23 under the action of elasticity, thereby moving away from the product that has been riveted.

[0042] In the aforementioned riveting mold, the product to be riveted is located between the forming component 25 and the riveting component 24. The upper clamping plate 11, close to the lower mold base 20, drives the pusher block 12 into the pusher station 26, sequentially pushing the stop block 23 and the riveting component 24. The stop block 23, through the sliding seat 22, drives the forming component 25 towards the product to be riveted, and the riveting component 24 moves along the sliding seat 22 towards the product to be riveted. During the process of pushing the riveting component 24, the pusher block 12 applies pressure to the riveting component 24 to press the product into the forming component 25, thereby completing the riveting. When the mold opens, the riveting component 24 and the stop block 23 elastically move closer to each other under the action of elasticity, moving away from the riveted product, thereby achieving material removal. This arrangement reduces the space occupied by the overall mechanism, thereby reducing the mold cost.

[0043] In some preferred embodiments, please continue to refer to Figure 2 , Figure 2 The diagram illustrates the structural relationship between the push block, riveting punch 242, and first elastic member 243 in this embodiment of the present invention. Specifically, the riveting assembly 24 includes a side push block 241, a riveting punch 242, and a first elastic member 243. The side push block 241 is slidably connected to the sliding seat 22 and elastically connected to the stop block 23. The riveting punch 242 is connected to the side push block 241 and is disposed towards the forming assembly 25. The end of the riveting punch 242 away from the side push block 241 has an abutment portion. The first elastic member 243 is sleeved on the riveting punch 242 and its opposite ends abut against the side push block 241 and the abutment portion, respectively. The side push slider 241 drives the riveting punch 242 to move toward the product to be riveted. During riveting, the first elastic element 243 is compressed so that the riveting punch 242 enters the forming component 25. As the mold opens, the push block 12 exits the push station 26, the side push slider 241 moves toward the stop block 23, and the first elastic element 243 springs open so that the riveting punch 242 disengages from the product that has been riveted, thereby achieving stripping.

[0044] In some more preferred embodiments, please refer to Figure 3 and Figure 4 , Figure 3 and Figure 4The diagram illustrates the structural relationship between the forming cavity 2511 and the riveting punch 242 in this embodiment of the invention. Specifically, the forming assembly 25 includes a forming block 251 and a stripping elastic member 252. The forming block 251 has a forming cavity 2511 on the side facing the riveting assembly 24. The stripping elastic member 252 is elastically connected to the forming block 251 and is positioned facing the riveting assembly 24. During riveting, the product enters the forming cavity 2511 under the pressure of the riveting punch 242. The stripping elastic member 252 is compressed, and the upper and lower plates are deformed by stamping to form an interlocking inlay structure, thereby completing the riveting. During stripping, the stripping elastic member 252 springs open, allowing the riveted product to detach from the forming cavity 2511.

[0045] Example 2:

[0046] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the riveting mold of this utility model. Please refer to the appendix. Figure 5 .

[0047] The push block 12 has an inclined first guide surface 121 on the side near the stop block 23, and the stop block 23 has a second guide surface 231 that cooperates with the first guide surface 121 to allow the push block 12 to enter the push station 26.

[0048] In this embodiment, the second guide surface 231 is inclined toward the riveting assembly 24 and is parallel to the first guide surface 121. The first guide surface 121 and the second guide surface 231 cooperate to make the push block 12 enter the push station 26 more smoothly, thereby ensuring the reliability of the riveting mold.

[0049] In some preferred embodiments, the push block 12 has an inclined third guide surface 122 on the side near the riveting assembly 24. The riveting assembly 24 has a fourth guide surface 244 that cooperates with the third guide surface 122 to allow the push block 12 to enter the push station 26. The fourth guide surface 244 is inclined toward the stop block 23 and parallel to the third guide surface 122. The third guide surface 122 and the fourth guide surface 244 cooperate with each other to allow the push block 12 to smoothly enter the push station 26, avoiding the problem that the push block 12 cannot enter the push station 26 when it is slightly deviated, thus affecting the riveting.

[0050] In some preferred embodiments, a second elastic element 245 is provided between the riveting assembly 24 and the stop block 23. The riveting assembly 24 and the stop block 23 are elastically connected by the second elastic element 245. When the push block 12 exits the push station 26, the riveting assembly 24 and the stop block 23 move closer to each other under the elastic action of the second elastic element 245, thereby achieving reset and facilitating the cyclic riveting operation.

[0051] In some preferred embodiments, the lower mold base 20 further includes a fixing block 27 and a third elastic element 28. The fixing block 27 is connected to the lower mold plate 21, and the opposite ends of the third elastic element 28 are respectively connected to the fixing block 27 and the sliding seat 22. When the push block 12 enters the push station 26, the stop block 23 is pushed, causing the sliding seat 22 to move, which compresses the third elastic element 28. When the push block 12 exits the push station 26, the third elastic element 28 springs open, causing the sliding seat 22 to move, so that the stop block 23 is reset.

[0052] In some more preferred embodiments, the lower mold base 20 further includes a limiting block 29, which is connected to the lower mold plate 21 and located between the riveting assembly 24 and the stop block 23. When the push block 12 exits the push station 26, and the riveting assembly 24 and the stop block 23 approach each other under the elastic action of the second elastic member 245, the limiting block 29, located between the riveting assembly 24 and the stop block 23, maintains a certain distance between them, facilitating the push block 12 to re-enter the push station 26.

[0053] Example 3:

[0054] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the riveting mold of this utility model. Please refer to the appendix. Figure 6 .

[0055] The riveting mold also includes a drive mechanism 30. There are two upper mold bases 10 and two lower mold bases 20. The two upper mold bases 10 are symmetrically arranged, and the two lower mold bases 20 are symmetrically arranged. The drive mechanism 30 is connected to the two upper mold bases 10.

[0056] In this embodiment, the drive mechanism 30 drives the two upper mold bases 10 to move so that the two upper mold bases 10 move close to the two lower mold bases 20 at the same time, and the two push blocks 12 enter the two push stations 26 respectively to perform riveting work, thereby saving energy consumption and improving riveting efficiency.

[0057] In some preferred embodiments, the riveting die further includes a guide post 40, which is telescopically connected between the upper clamping plate 11 and the lower mold plate 21. The drive mechanism 30 is located between the two upper clamping plates 11. When the upper clamping plate 11 approaches the lower mold base 20 under the drive of the drive mechanism 30, the guide post 40 retracts; when the upper clamping plate 11 moves away from the lower mold base 20 under the drive of the drive mechanism 30, the guide post 40 extends, thereby improving the connection stability between the upper clamping plate 11 and the lower mold base 20, and thus making the overall mechanism more reliable.

[0058] In this riveting mold, the product to be riveted is located between the forming component 25 and the riveting component 24. The upper clamping plate 11, close to the lower mold base 20, drives the pusher block 12 into the pusher station 26, sequentially pushing the stop block 23 and the riveting component 24. The stop block 23, through the sliding seat 22, drives the forming component 25 towards the product to be riveted, and the riveting component 24 moves along the sliding seat 22 towards the product to be riveted. During the process of pushing the riveting component 24, the pusher block 12 applies pressure to the product to be riveted, pressing the product into the forming component 25, thereby completing the riveting. When the mold opens, the riveting component 24 and the stop block 23 elastically move closer to each other under the action of elasticity, moving away from the riveted product, thereby achieving material removal. This arrangement reduces the space occupied by the overall mechanism, thereby reducing the mold cost.
