[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] One preferred embodiment of this application, such as Figures 1 to 9 As shown, a feeding and positioning component of an in-mold riveting system includes a stamping die body (which includes an upper die 1 and a lower die 2), a feeding guide rail 4, and a feeding mechanism 3. A riveting joint 6 is provided in the upper die 1, and a riveting station 5 is provided in the lower die 2. The feeding guide rail 4 is mounted on the lower die 2 and cooperates with the riveting station 5. The unloading end of the feeding mechanism 3 is detachably connected to the feeding guide rail 4 through a snap-fit ​​structure 9.

[0030] Understandably, stamping dies can punch, chamfer, trim, bend, and shape strips, and finally cut them into blanks. The riveting process occurs between the forming and blanking processes. The structural shape formed by the strip after the forming process is called Product A. This design directly rivets Product A after it has been formed, resulting in Product A having pre-riveted rivets after blanking. This eliminates the need for an additional riveting line, saving time and improving production efficiency. Furthermore, since the riveting process is completed automatically within the die, it avoids errors that may occur with manual operation, improving riveting accuracy and product quality.

[0031] Specifically, during riveting, the feeding mechanism 3 can transport the rivet to the feeding guide rail 4, and then the feeding guide rail 4 can transport it to the riveting station 5. When the formed product A is transported to the riveting station 5, the upper mold 1 and the lower mold 2 close the mold. At this time, the riveting head 6 in the upper mold 1 will rivet the product A to the rivet in the riveting station 5, thereby realizing the in-mold riveting process of the product A.

[0032] It should be noted that the automatic feeding of the strip (i.e., product A) is existing technology in stamping dies, and how the riveting joint 6 performs the riveting is also existing technology known to those skilled in the art, so it will not be described in detail. Furthermore, in existing riveting equipment, the riveting pressure generally requires a separate drive device (e.g., a hydraulic cylinder). However, in in-die riveting, when the die is closed (stamping), mechanical or hydraulic force tightly connects the rivet or rivet to another part. That is, the die itself can provide sufficient pressure for riveting, thus eliminating the need for an additional drive device, further simplifying the equipment structure and reducing costs. Of course, the specific riveting process is independent of the die, so each rivet joint 6 can be applied to different riveting situations. For example, in in-die riveting with a progressive die, the stamping action of the die drives the rivet joint 6 to apply pressure to the rivet (or rivet), connecting them to the corresponding parts and ultimately completing the riveting process.

[0033] As a further description of the above embodiments: as Figure 4 As shown, the feeding guide rail 4 includes a fixed guide rail 401 and a movable guide rail 402. The fixed guide rail 401 is fixedly installed on the lower mold 2 and connected to the unloading end (of the feeding mechanism 3). The movable guide rail 402 is vertically slidably installed on the lower mold 2 and connected to the lower mold 2 through the adjustment component 8. The two ends of the movable guide rail 402 are respectively docked with the fixed guide rail 401 and the riveting station 5.

[0034] It is understandable that, during the actual riveting process, the arrangement of the feeding guide 4 may interfere with the riveting of product A. For example: Figure 1 As shown, product A has curved ends and a riveting joint in the middle. Therefore, when product A is laid flat, the feeding guide 4 obstructs its movement. Thus, in this design, the feeding guide 4 is divided into a movable guide 402. Specifically, during riveting, the movable guide 402 can move vertically downwards with the assistance of the adjusting component 8. Figure 4 As shown, the space created by this downward movement allows for the flat riveting of product A, enabling the riveting process to proceed smoothly.

[0035] On the other hand, after the movable guide rail 402 moves downward, the feeding guide rail 4 and the riveting station 5 are disengaged. This ensures that the riveting station 5 is independent during the riveting process, meaning that the riveting station 5 has exactly one rivet, and this rivet is not subject to the conveying force of other rivets, further improving the accuracy and stability of riveting. This application mainly focuses on conveying rectangular rivets; that is, the feeding guide rail 4 adopts a rectangular shape adapted to the rectangular rivet, thus preventing axial rotation of the rectangular rivet during conveying. This ensures that each riveting operation is performed in the accurate position, improving the accuracy and consistency of riveting.

[0036] This application does not specifically limit the structure of the adjustment component 8, but includes, but is not limited to, the following two:

[0037] Structure 1: The adjusting component 8 includes an elastic element (e.g., a spring), with both ends connected to the movable guide rail 402 and the lower mold 2, respectively. It can be understood that when the upper mold 1 and lower mold 2 are closed, the upper mold 1 will press the movable guide rail 402 downwards. When the upper mold 1 and lower mold 2 are opened (separated), the movable guide rail 402 loses the pressing effect of the upper mold 1 and, under the action of the elastic force, returns to its original position and moves upwards.

[0038] Structure 2: The adjusting component 8 includes a telescopic device, which is installed on the lower mold 2 and its piston end is connected to the movable guide rail 402. The telescopic device is also electrically connected to the control system of the stamping die. Understandably, during mold closing, the telescopic device shortens and automatically moves the movable guide rail 402 downwards; during mold opening, the telescopic device extends and automatically moves the movable guide rail 402 upwards, thus accommodating the riveting process of product A.

[0039] It should be noted that structure one utilizes the inherent properties of the spring for adaptive up-and-down movement, while structure two uses a telescopic device for precise up-and-down movement control. Both methods can meet practical needs, and those skilled in the art can choose according to the specific circumstances. It should be understood that the specific structure and working principle of the telescopic device mentioned above are well-known to those skilled in the art, and therefore will not be described in detail here. Common telescopic devices include hydraulic cylinders, pneumatic cylinders, and linear motors, etc., and those skilled in the art can choose according to actual needs. Of course, the control circuit of the control system can be implemented by those skilled in the art through simple programming, which is also common knowledge in the field; therefore, the control method and circuit connection will not be explained in detail.

[0040] It should be known that, as Figure 4 As shown, when the movable guide rail 402 moves downward and separates from the fixed guide rail 401, the feeding mechanism 3 should stop conveying. Otherwise, the rivets inside the fixed guide rail 401 will continue to move and fall to the top of the movable guide rail 402, causing them to scatter everywhere. The rivets will also interfere with the closing of the stamping die, potentially damaging it. Since the stamping process is rapid and continuous, if the feeding mechanism 3 constantly performs a "stop-start" cycle, it is prone to malfunction. Furthermore, the rivets inside the fixed guide rail 401 are in a free state during this time, making them susceptible to falling under the vibration of the stamping process.

[0041] Therefore, to solve the above technical problems, two methods can be used:

[0042] Method 1: For example Figure 5 and Figure 6 As shown, a positioning rod 7 can be installed inside the upper mold 1. Understandably, during the riveting process, the positioning rod 7 moves downwards under the influence of the upper mold 1, allowing it to insert into any rivet post within the fixed guide rail 401. This locks the rivet post, stopping its feeding; in other words, there is no need to stop the feeding mechanism 3. Conversely, when the upper mold 1 moves the positioning rod 7 upwards to open the mold, the locking of the rivet post is released, allowing it to continue feeding, and the next rivet post will slide into the position corresponding to the positioning rod 7.

[0043] Further preferably, the locking rivet is located near the movable guide rail 402, such as... Figure 4 As shown, this is the rivet at point a; in layman's terms, it is locking the rivet located at the very end of the fixed guide rail 401, because the rivet at this point is most likely to slide out of the fixed guide rail 401, so locking it can prevent the rivet from falling off.

[0044] It should be noted that if a separate feeding guide rail 4 structure is used, that is, there is no need to set up a movable guide rail 402 to avoid interference with product A, then the positioning rod 7 can be inserted into any rivet post in the feeding guide rail 4. This can cut off the conveying force of the rivet post, so that the rivet post in the riveting station 5 will not be affected by the conveying force during the riveting process.

[0045] Method 2 (not shown): A baffle is installed on the side of the movable guide rail 402 near the fixed guide rail 401. The baffle has a guide groove that mates with the fixed guide rail 401. It can be understood that during riveting, the baffle can move downwards under the action of the movable guide rail 402, causing the guide groove to misalign with the fixed guide rail 401. In this case, the baffle can block the tail of the fixed guide rail 401, thereby stopping the conveying of the rivet.

[0046] It should be noted that the first method is the simplest and most reliable because the rivet has a through hole in the middle, and the bottom of the positioning rod 7 can be tapered, allowing the positioning rod 7 to be easily inserted into the through hole, thereby achieving (alignment) locking of the rivet. When using the second method, it is necessary to ensure that the rivet at the tail of the fixed guide rail 401 and the rivet at the head of the movable guide rail 402 are aligned with the baffle, and preferably, both the top of the rivet and the inner top of the guide groove have chamfered structures; otherwise, hard compression damage between the baffle and the rivet can easily occur. In the case of a rectangular rivet in this application, the positioning rod 7 is the preferred configuration. Those skilled in the art can also choose to use the structure in the second method when combining rivets (or rivets) of other structural forms.

[0047] In one embodiment of this application, such as Figure 2 , Figure 3 and Figure 7 As shown, the feeding mechanism 3 includes a vibratory plate 301, a guide hose 302, and a guide connector 303. The two ends of the guide hose 302 are connected to the vibratory plate 301 and the guide connector 303, respectively. The guide connector 303 forms the unloading end of the feeding mechanism 3, and the feeding mechanism 3 cooperates with the feeding guide rail 4 to ensure that the conveying direction of the rivet column is perpendicular to the conveying direction of product A.

[0048] Specifically, such as Figure 3 As shown, the conveying direction of product A is x, and the conveying direction of the rivet is y. x and y are perpendicular to each other. This arrangement allows the rivet to fall smoothly into the feeding guide rail 4 and the riveting station 5, avoiding skewing or jamming of the rivet during the conveying process. Of course, the (feeding) vibratory feeder 301 is also a device known to those skilled in the art, so its structure and principle will not be described in detail.

[0049] Furthermore, the flexible design of the material guide hose 302 allows it to bend adaptably according to different working environments and needs during the specific installation process, while the snap-fit ​​structure 9 allows the material guide connector 303 to be quickly disassembled, thereby ensuring that the feeding mechanism 3 can be flexibly installed and disassembled to adapt to different installation requirements.

[0050] As a further description of the above embodiments: as Figure 8 and Figure 9 As shown, a slot 10 is provided at the bottom of the material guide joint 303, and the buckle structure 9 includes a buckle post 901. The buckle post 901 (by means of a spring) is elastically and vertically slidably installed at the front end of the feeding guide rail 4 (i.e., the fixed guide rail 401).

[0051] Understandably, during installation, the guide connector 303 is inserted into the feeding guide rail 4. At this time, the clamping post 901 compresses the spring under the pressure. When the groove 10 at the bottom of the guide connector 303 aligns with the clamping post 901, the clamping post 901 moves upward under the elastic force and enters the groove 10, thereby locking the guide connector 303. For disassembly, simply pull the clamping post 901 downward to separate it from the groove 10, and then pull out the guide connector 303; it is simple and convenient.

[0052] Further optimization, such as Figure 9As shown, a groove 11 is provided on the outside of the locking post 901. The latching structure 9 also includes an operating rod 902, which is rotatably mounted inside the feeding guide rail 4, with its first end (left end) engaging with the groove 11. It can be understood that during disassembly, rotating the second end (right end) of the operating rod 902 upwards causes the first end (left end) of the operating rod 902 to rotate downwards and press against the bottom of the groove 11, driving the locking post 901 downwards until it moves away from the groove 10, thus releasing the locking of the guide connector 303. This method changes the previous method of pulling down the locking post 901 from the bottom (of the feeding guide rail 4) to a method that only requires pressing and rotating at the front end (of the feeding guide rail 4), making it easier for operators to operate.

[0053] Further optimization involves setting the rotating mounting point of the operating lever 902 within the feeding guide rail 4 as the rotation point, thereby dividing the operating lever 902 into two parts around the rotation point: the first section (i.e., the left section) and the second section (i.e., the right section). The first section engages with the groove 11, while the second section is the operating end. The second section is longer than the first section, and its longer length provides a larger lever arm. Based on the lever principle, this makes it easier for the operator to press the lever.

[0054] Further optimization, such as Figure 8 and Figure 9 As shown, the structure of the operating lever 902 can be configured as follows: its first segment is a straight line (i.e., a straight structure), and its second segment is a U-shaped structure, with the first segment connected to the middle of the second segment. We know that the operating lever 902 is located at the front end of the feeding guide rail 4, and the guide connector 303 is also inserted from the front end of the feeding guide rail 4. This means that the connected operating lever 902 would be located directly below the guide connector 303 and the guide hose 302, thus obstructing subsequent movement of the operating lever 902. However, this design uses the aforementioned special structure for the operating end, allowing the operating lever 902 to be located below and to the sides of the guide connector 303, thus enabling convenient movement of the operating lever 902 and quick assembly / disassembly of the guide connector 303.

[0055] The specific working method of this application includes the following steps:

[0056] S100: First, the feeding mechanism 3 will orderly transport the rivet columns through the feeding guide rail 4 to the riveting station 5 in the lower mold 2.

[0057] S200: When the upper mold 1 and the lower mold 2 are closed, the movable guide rail 402 in the feeding guide rail 4 moves down synchronously, thereby providing clearance space for the riveting of product A; and at this time, the rivet in the feeding guide rail 4 stops being fed under the action of the positioning rod 7, which can prevent the rivet from being fed too much, and at this time there is only one rivet in the riveting station 5.

[0058] S300: After the upper mold 1 and the lower mold 2 are closed, the riveting process is carried out. That is, the riveting joint 6 in the upper mold 1 rivets the rivet post to the product A, thereby completing the riveting of the product A on the strip.

[0059] S400: The upper mold 1 and the lower mold 2 are separated by mold opening. At this time, the movable guide rail 402 is reset under the action of the adjusting component 8, and the rivet in the feeding guide rail 4 continues to be conveyed to the riveting station 5, thus preparing for the riveting of the next product A; finally, the strip will advance one pitch under the action of the stamping die, that is, the next product A moves to the riveting station 5.

[0060] S500: Repeat steps S200 to S400 above until the stamping and riveting of product A on the entire strip is completed.

[0061] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments.
