Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to a dual-axis linkage edge-binding mechanism. Background Technology

[0002] With the rapid development of the automotive industry, stamping die structures are constantly innovating and accumulating, meeting the personalized requirements of product design while reducing manufacturing costs. Existing technologies, such as the Chinese invention patent with publication number CN104399795A, require a lateral cylinder to provide the forming power source. The mechanism needs to complete the pre-bending and pressing actions of the edge banding under the drive of the cylinder. Specifically, in the aforementioned patent, the lower die-driven hydraulic cylinder provides the forming force source required for primary pre-bending, secondary free pre-bending, and pressing edge banding. The mechanism includes a pre-bending preparation process and a pre-bending process. The pre-bending preparation process involves the pressure plate drive cylinder driving the inner plate forward pressure assembly to move downwards along the guide rail to the forward pressure section, pressing the inner and outer plates on the lower die base. The lateral pressure drive cylinder drives the lateral pressure punch to press the outer surface of the edging-related part laterally. The edging drive cylinder drives the bracket and the pre-bending composite blade block on it to move horizontally, bringing the first pre-bending surface of the pre-bending composite blade block to the working position. The pre-bending process involves the lower die base moving upwards along the guide post under the drive of the lower die drive hydraulic cylinder. The outer plate edging surface contacts the first pre-bending surface of the pre-bending composite blade block, completing the pre-bending forming. The edging angle of the large-angle edging (105°–150°) is pre-bent to 90°. The inner plate forward pressure assembly is always in a forward pressure working state and can move up and down responsively to the lower die base.

[0003] However, the aforementioned patents have complex mechanisms that require forward pressing, and the influence of external power sources makes it difficult to achieve stable quality. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-axis linkage edge-binding mechanism to solve the problem that existing edge-binding mechanisms require forward pressing.

[0005] The present invention provides a dual-axis linkage edging mechanism, including a first driving block, a first rotating component disposed on the lower side of the first driving block, a linkage member connected to the first rotating component, and an edging component connected to the linkage member. The first rotating component includes a first base, a rotating rod rotatably connected to the first base, and a connecting block rotatably connected to the lower end of the rotating rod. The other end of the connecting block is rotatably connected to the linkage member, and the other end of the linkage member is fixedly connected to the edging component.

[0006] The aforementioned dual-axis linkage edge-wrapping mechanism drives the rotating rod to rotate away from the edge-wrapping component via the first drive block, thereby driving the lower connecting block to move towards the edge-wrapping component. Through the linkage, the edge-wrapping component is moved forward to the edge-wrapping position of the product. Then, the edge-wrapping component performs pre-edge wrapping and wrapping of the product. This achieves precise control of multiple compound actions, including the advancement of the edge-wrapping component, pre-edge wrapping, and wrapping, all completed in one go. This simplifies the mechanism and eliminates the need for a positive pressure blade block.

[0007] Furthermore, the edge-binding assembly includes a second base, a second drive block, a second rotating assembly disposed on the lower side of the second drive block, an edge-binding pressure block connected to the rotating end of the second rotating assembly, and a rotating assembly rotatably connected to the lower end of the edge-binding pressure block. The second rotating assembly is rotatably connected to the middle part of the second base, and the other end of the rotating assembly is rotatably connected to the lower side of the second base. Furthermore, the second rotating assembly includes a rotating block and a first rotating shaft disposed at the lower end of the rotating block, the first rotating shaft being rotatably connected to the second base. Furthermore, the rotating rod is rotatably connected to the first base via a second rotating shaft. Furthermore, the rotating assembly includes a third rotating shaft, a rotating connecting block rotatably connected to the third rotating shaft, and a fourth rotating shaft. The rotating connecting block is rotatably connected to the lower side of the second base through the fourth rotating shaft. The edge-sealing pressure block includes a connecting plate and a pressure plate fixedly disposed on the upper end of the connecting plate. One end of the connecting plate is connected to the rotating end of the second rotating assembly through a fifth rotating shaft, and the other end is rotatably connected to the third rotating shaft. Furthermore, two first guide rods are rotatably connected to the lower side of the rotating rod. One end of the first guide rod is rotatably connected to the rotating rod, and the other end is connected to the side of the first base away from the edge-binding assembly. Furthermore, a second guide rod is provided on each side of the lower end of the connecting plate. One end of the second guide rod is rotatably connected to the lower end of the connecting plate, and the other end is rotatably connected to the upper side of the second base.

Furthermore, the upper end of the rotating block is provided with a second roller, and the rotating block is rotatably connected to the second drive block through the second roller.

[0014] Please see Figures 1 to 4 The present invention provides a dual-axis linkage edge-binding mechanism, including a first drive block 10, a first rotating component 20 disposed on the lower side of the first drive block 10, a linkage member 30 connected to the first rotating component 20, and an edge-binding component 40 connected to the linkage member 30. The first rotating component 20 includes a first base 21, a rotating rod 22 rotatably connected to the first base 21, and a connecting block 23 rotatably connected to the lower end of the rotating rod 22. The other end of the connecting block 23 is rotatably connected to the linkage member 30, and the other end of the linkage member 30 is fixedly connected to the edge-binding component 40.

[0015] The aforementioned dual-axis linkage edge-binding mechanism drives the rotating rod 22 to rotate away from the edge-binding component 40 via the first drive insert 10, thereby driving the lower connecting block 23 to move towards the edge-binding component 40. Through the linkage 30, it drives the edge-binding component 40 to move forward to the edge-binding position of the product. Then, the edge-binding component 40 performs pre-edge binding and wrapping of the product, achieving precise control of multiple compound actions such as the advancement of the edge-binding component, pre-edge binding, and wrapping, all completed in one go. This simplifies the mechanism and eliminates the need for a positive pressure blade block.

[0016] In one embodiment of the present invention, the edge-binding assembly 40 includes a second base 41, a second drive block 42, a second rotating assembly 43 disposed below the second drive block 42, an edge-binding pressure block 44 connected to the rotating end of the second rotating assembly 43, and a rotating assembly 45 rotatably connected to the lower end of the edge-binding pressure block 44. The second rotating assembly 43 is rotatably connected to the middle of the second base 41, and the other end of the rotating assembly 45 is rotatably connected to the lower side of the second base 41. Specifically, the second drive block 42 is connected to a drive source such as a robotic arm or a drive motor to drive the second rotating assembly 43 to rotate, thereby driving the edge-binding pressure block 44 to pre-bind the product. Then, the edge-binding pressure block 44 drives the rotating assembly to rotate, thereby driving the lower end of the edge-binding pressure block 44 to rotate around the second base 41 through the rotating assembly 45, thereby achieving the binding of the product. In one embodiment of the present invention, the second rotating assembly 43 includes a rotating block 431 and a first rotating shaft 432 disposed at the lower end of the rotating block 431, the first rotating shaft 432 being rotatably connected to the second base 41. Specifically, the second driving insert 42 is connected to a driving source such as a robotic arm or a drive motor, driving the rotating block 431 to rotate around the first rotating shaft 432, thereby driving the edge-wrapping pressure block 44 at the free end of the rotating block 431 to rotate, realizing the pre-wrapping function. In one embodiment of the present invention, the rotating rod 22 is rotatably connected to the first base 21 via a second rotating shaft 24 to realize the rotation function of the rotating rod 22. In one embodiment of the present invention, the rotating assembly 45 includes a third rotating shaft 451, a rotating connecting block 452 rotatably connected to the third rotating shaft 451, and a fourth rotating shaft 453. The rotating connecting block 452 is rotatably connected to the lower side of the second base 41 via the fourth rotating shaft 453. The edge-sealing pressure block 44 includes a connecting plate 441 and a pressure plate 442 fixedly disposed on the upper end of the connecting plate 441. One end of the connecting plate 441 is connected to the rotating end of the second rotating assembly 43 via a fifth rotating shaft 443, and the other end is rotatably connected to the third rotating shaft 451. Specifically, the second driving insert 42, through cooperation with the second roller 80 at the upper end of the rotating block 431, drives the rotating block 431 to rotate around the first rotating shaft 432 as the axis. When the rotating block 431 rotates, it drives the connecting plate 441 of the edge-sealing pressing block to rotate through the fifth rotating shaft 443. At the same time, since the connecting plate 441 is rotatably connected to the third rotating shaft 451 of the rotating component 45, the rotating component 45 will rotate with the rotation of the connecting plate 441, so that the edge-sealing pressing block 44 can perform pre-edge sealing and sealing actions on the product. In one embodiment of the present invention, two first guide rods 50 are rotatably connected to the lower side of the rotating rod 22. One end of each first guide rod 50 is rotatably connected to the rotating rod 22, and the other end is connected to the side of the first base 21 away from the edge-binding assembly 40. A second guide rod 60 is provided on each side of the lower end of the connecting plate 441. One end of each second guide rod 60 is rotatably connected to the lower end of the connecting plate 441, and the other end is rotatably connected to the upper side of the second base 41. The first guide rods 50 and the second guide rods 60 respectively guide and stabilize the rotation of the rotating rod 22 and the connecting plate 441. In one embodiment of the present invention, a first roller 70 is provided at the upper end of the rotating rod 22, and the upper end of the rotating rod 22 is rotatably connected to the first drive block 31 through the first roller 70, so that the rotating rod 22 can rotate smoothly. In one embodiment of the present invention, the upper end of the rotating block 431 is provided with a second roller 80, and the rotating block 431 is rotatably connected to the second drive plug 42 through the second roller 80.

[0017] In one embodiment of the present invention, the lower end of the first drive plug 21 is provided with a snap-fit ​​notch (not shown in the figure).

[0018] In the aforementioned dual-axis linkage hemming mechanism, when hemming is required on the product, the driving device, such as a drive motor, engages with the locking notch at the lower end of the first drive block 10 to drive the first drive block 10 to move. The first drive block 10, through its engagement with the first roller 70 at the upper end of the rotating rod 22, drives the rotating rod to rotate around the second rotating shaft 24 in a direction away from the hemming assembly 40. During the rotation of the rotating rod 22, since the rotating rod 22 is rotatably connected to the connecting block 23, the connecting block 23 moves towards the hemming assembly 40 as the rotating rod 22 rotates. The connecting block 23 drives the linkage 30 to move, which in turn drives the hemming assembly 40 forward to the hemming position of the product. At this time, the driving device drives the second drive block 42 to move. The second drive block 42, through its engagement with the second roller 80 at the upper end of the rotating block 431, drives the rotating block 431 to rotate around the first rotating shaft 432. When the rotating block 431 rotates, it drives the connecting plate 441 of the edge-sealing pressing block to rotate via the fifth rotating shaft 443. Simultaneously, since the connecting plate 441 is rotatably connected to the third rotating shaft 451 of the rotating assembly 45, the rotating assembly 45 rotates along with the connecting plate 441, enabling the edge-sealing pressing block 44 to perform pre-edge sealing and sealing actions on the product. Throughout the process, the first guide rod 50 and the second guide rod 60 respectively guide and stabilize the rotation of the rotating rod 22 and the connecting plate 441, ensuring the accuracy of the edge-sealing action.

[0019] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
