Description

Technical Field

[0001] This utility model relates to the field of vehicle parts processing technology, and more specifically, to an integrated mold for bending and punching trim strips. Background Technology

[0002] T-shaped or "T"-shaped curved trim strips are commonly used in automotive design for specific areas, such as door edges. These strips serve several functions: impact protection (the shape often provides good impact protection, preventing damage to doors and other parts during daily use); visual appeal (the T-shaped design enhances the car's appearance, making it look more sporty or stylish); and sealing performance (they typically create a better seal with other parts of the car body, reducing noise and moisture infiltration). However, current production of these trim strips generally requires multiple processes, each with its own processing equipment. For example, in some technologies, straight trim strips are first shaped into a curved form matching the door shape using a bending die, then transferred to the next process where specialized punching equipment punches holes in the bent trim strip to connect it to the door or subsequent sealing structure. The overall manufacturing process is complex, requires numerous processing equipment, and has relatively high production efficiency and costs. Utility Model Content

[0003] This utility model aims to solve at least one of the above-mentioned technical problems.

[0004] To address the aforementioned problems, this utility model provides an integrated mold for bending and punching decorative strips, comprising a base plate, a bending forming template, a template support, a punching device, and a punching support. The bending forming template is suspended on the base plate via the template support. The front side of the bending forming template has a bending forming cavity for bending straight decorative strips into curved decorative strips, and the rear side of the bending forming template also has a template hole communicating with the bending forming cavity. The punching device is suspended on the base plate via the punching support, and the punching device includes a punching mechanism and a pressing mechanism. The pressing mechanism is used to press and fix the curved decorative strip within the bending forming cavity, and the punching mechanism is used to punch holes in the curved decorative strip through the template hole.

[0005] The present invention provides an integrated mold for bending and punching decorative strips, which, compared with the prior art, has, but is not limited to, the following technical effects:

[0006] The bending forming template is suspended on the base plate via a template support at the bottom. The front of the bending forming template has a bending forming cavity for bending straight trim strips into curved trim strips. That is, before bending, the trim strip is a straight strip. Both ends of the straight strip can be clamped and fixed by an external clamping mechanism. The clamping mechanism then moves the straight strip backward and into the bending forming cavity until it is bent into a curved trim strip. After the curved trim strip is formed, the pressing mechanism of the punching device presses and fixes it within the bending forming cavity, preparing it for subsequent punching operations. Then, the punching mechanism punches holes in the pressed curved trim strip through the template holes on the rear side of the bending forming template, creating trim strip holes. Ultimately, this integrated bending and punching mold for trim strips combines bending and punching functions, simplifying the trim strip processing, reducing processing equipment, improving production efficiency, and lowering the production cost of the trim strips.

[0007] Furthermore, the clamping mechanism includes a clamping cylinder, a pull rod, a moving shaft, a sleeve, a swing rod, and a pressure block.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the attached diagram, the Z-axis represents the vertical direction, that is, the up-down direction, with the positive direction of the Z-axis indicating up and the negative direction indicating down; the Y-axis represents the horizontal direction, that is, the left-right direction, with the positive direction of the Y-axis indicating left and the negative direction indicating right; the X-axis represents the vertical direction, that is, the front-back direction, with the positive direction of the X-axis indicating front and the negative direction indicating back. It should also be noted that the aforementioned representations of the Z, Y, and X axes are merely for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model.

[0033] See Figure 1 , Figure 4 , Figure 6-7 as well as Figure 9 This utility model discloses an integrated mold for bending and punching decorative strips, comprising a base plate 1, a bending forming template 2, a template support 3, a punching device 4, and a punching support 5. The bending forming template 2 is suspended on the base plate 1 via the template support 3. The front side of the bending forming template 2 is provided with a bending forming cavity 21 for bending a straight decorative strip 81 into a curved decorative strip 82, and the rear side of the bending forming template 2 is also provided with a template hole 22 communicating with the bending forming cavity 21. The punching device 4 is suspended on the base plate 1 via the punching support 5. The punching device 4 includes a punching mechanism 41 and a pressing mechanism 42. The pressing mechanism 42 is used to press and fix the curved decorative strip 82 in the bending forming cavity 21, and the punching mechanism 41 is used to punch the curved decorative strip 82 through the template hole 22.

[0034] In this context, the bending and forming template 2 is suspended on the base plate 1 via the template support 3. This means that the bending and forming template 2 is positioned at the top of the template support 3, and the bottom of the template support 3 is positioned on the base plate 1, thus making the bending and forming template 3 higher than the base plate 1, i.e., the bending and forming template 3 is suspended on the base plate 1. Similarly, the punching device 4 is suspended on the base plate 1 via the punching support 5, which has the same meaning and will not be explained further here.

[0035] In this embodiment, the bending forming template 2 can be suspended on the base plate 1 via the template support 3 at the bottom. The front side of the bending forming template 2 is provided with a bending forming cavity 21 for bending the straight trim 81 into a curved trim 82. That is, the curved trim 82 is a straight trim 81 before bending. The two ends of the straight trim 81 can be clamped and fixed by the external clamping mechanism 9. Then, the clamping mechanism 9 can move the straight trim 81 backward and into the bending forming cavity 21 until the straight trim 81 is bent in the bending forming cavity 21 to form the curved trim 82. After the curved trim 82 is formed, the bending trim 82 can be pressed and fixed in the bending forming cavity 21 by the pressing mechanism 42 of the punching device 4 to prepare for the subsequent punching operation. Then, the punching mechanism 41 can punch the pressed curved trim 82 through the template hole 22 on the rear side of the bending forming template 2 to form trim holes 821 on the curved trim 82. The final product is an integrated bending and punching mold for decorative strips, which combines bending and punching functions, simplifies the processing of decorative strips, reduces the amount of processing equipment, improves production efficiency, and lowers the production cost of decorative strips.

[0036] Among them, such as Figure 9 As shown, the final required curved trim 82 can have a T-shaped cross-section. Before bending, the curved trim 82 is a straight trim 81. The straight trim 81 refers to the fact that its extension direction is a straight line. The cross-sectional shape of the straight trim 81 is also a T-shape. Figure 1 , Figure 4 , Figure 6-7 As shown, it can be understood that since the bending forming cavity 21 is not a straight cavity but a curved cavity, the distance between the cavity and the straight trim 81 is not the same at different positions. When the external clamping mechanism 9 bends the straight trim 81, it first clamps the left and right ends of the straight trim 81, and then the external clamping mechanisms 9 at both ends move backward synchronously to drive the straight trim 81 to move backward. During the backward movement, the position of the straight trim 81 closest to the bending forming cavity 21 first contacts the X-axis, until the other positions of the straight trim 81 gradually contact the corresponding positions of the bending forming cavity 21 in sequence. When the bending forming cavity 21 contacts the trim at all positions in the extension direction, it means that the straight trim 81 has been bent into a curved trim 82 in the bending forming cavity 21. Then the clamping mechanism 9 can release the curved trim 82 and remove it.

[0037] See Figure 1-3 as well as Figure 6-8Optionally, the clamping mechanism 42 includes a clamping cylinder 421, a pull rod, a moving shaft 424, a sleeve 422, a swing rod 423, and a pressure block 425. The cylinder body of the clamping cylinder 421 is fixedly connected to the sleeve 422 and located on the lower side of the bending forming template 2. The pull rod is located inside the sleeve 422, and one end of the pull rod is connected to the piston rod of the clamping cylinder 421. The other end of the pull rod is connected to the moving shaft 424. One end of the swing rod 423 is hinged to the moving shaft 424 and used to swing around the moving shaft 424. The pressure block 425 is disposed on the upper side of the other end of the swing rod 423. The clamping cylinder 421 is used to drive the moving shaft 424 and one end of the swing rod 423 to enter and exit the sleeve 422 via the pull rod.

[0038] In this embodiment, as Figure 1-3 As shown, before the straight trim strip 81 enters the bending forming cavity 21, the pressing cylinder 421 can be extended first, and then the piston rod of the pressing cylinder 421 extends forward to drive the pull rod in the sleeve 422 to move forward. Then the pull rod drives the moving shaft 424 and the swing rod 423 to move forward. The swing rod 423 that moves forward also drives the front end pressure block 425 to move forward, so that the pressure block 425 and the bending forming template 2 are spaced apart. When the forward-moving lever pushes the moving shaft 424 forward out of the sleeve 422, the end of the swing rod 423 that is hinged to the moving shaft 424, that is, the rear end of the swing rod 423, will also extend out of the sleeve 422. At this time, the swing rod 423 is not constrained by the sleeve 422, and thus the swing rod 423 will swing downward around the moving shaft 424 under gravity. After the swing rod 423 swings downward, the end away from the moving shaft 424, that is, the front end of the swing rod 423, will become lower, thereby causing the pressure block 425 to become lower (at least lower than the bending forming cavity 21). This state of the pressing mechanism 42 can be called the avoidance state.

[0039] When the clamping mechanism 42 is in the avoidance state, the clamping mechanisms 9 at both ends of the straight trim 81 can drive the straight trim 81 to move backward until a curved trim 82 is formed in the bending forming cavity 21. The pressure block 425 of the clamping mechanism 42 in the avoidance state will not interfere with the backward movement of the straight trim 81.

[0040] As mentioned earlier, after the curved trim 82 is formed in the bending forming cavity 21, the external clamping mechanism 9 can release the curved trim 82 and remove it. Then, the curved trim 82 in the bending forming cavity 21 is punched. Specifically, the pressing mechanism 42 is first controlled to move from the avoidance state to the pressing state to press and fix the curved trim 82 in the bending forming cavity 21. Only then can the punching mechanism 41 punch the curved trim 82 through the template hole 22.

[0041] The principle of controlling the pressing mechanism 42 to move from the avoidance state to the pressing state is as follows: the pressing cylinder 421 is controlled to retract, and then the piston rod drives the pull rod inside the sleeve 422 to move backward. The pull rod moving backward will pull the moving shaft 424 outside the sleeve 422 back into the sleeve 422. After the moving shaft 424 is pulled back into the sleeve 422, the rear end of the swing rod 423 will also be pulled back into the sleeve 422 by the moving shaft 424. Then, under the constraint of the sleeve 422, the swing rod 423 will return to the horizontal state (parallel to the XY plane), and then drive the pressure block 425 at the front end of the swing rod 423 to be straightened. After being straightened, the pressure block 425 is aligned with the height position of the bending forming cavity 21 on the rear side. Afterward, as the pressing cylinder 421 continues to retract, the swing rod 423 will drive the pressure block 425 to continue to move backward until the pressure block 425 presses against the curved trim 82 inside the bending forming cavity 21. At this point, the clamping mechanism 42 has completed its movement from the avoidance state to the clamping state, as follows: Figure 6-8 As shown.

[0042] See Figure 1-2 , Figure 4 , Figure 6 and Figure 9 Optionally, multiple punching devices 4 are provided, and the multiple punching devices 4 are distributed sequentially along the extension direction of the bending forming template 2, and multiple template holes 22 are distributed sequentially along the extension direction of the bending forming template 2. Therefore, when it is necessary to punch the bent trim 82 within the bending forming cavity 21, the bending trim 82 can be pressed at different positions by the pressure blocks 425 of the multiple pressing mechanisms 42 in the multiple punching devices 4. At the positions where the bent trim 82 is pressed by each pressure block 425, the corresponding punching mechanism 41 can perform the punching.

[0043] See Figure 2-3 and Figure 6-9 Optionally, the punching mechanism 41 includes a punching cylinder 411 and a punch 412. The punching cylinder 411 is located on the rear side of the bending forming template 2. One end of the punch 412 is connected to the piston rod of the punching cylinder 411. The punching cylinder 411 is used to drive the other end of the punch 412 to be inserted into the bending forming cavity 21 through the template hole 22 to punch the bent trim 82.

[0044] In this embodiment, after the pressing block 425 of the pressing mechanism 42 in the pressing state presses and fixes the curved trim 82, the punching cylinder 411 on the rear side of the bending forming template 2 can be controlled to extend, thereby driving the punch 412 to move forward and extend into the template hole 22. As the punching cylinder 411 extends, the punch 412 punches a hole at the corresponding position of the pressed curved trim 82, forming a trim hole 821. After punching is completed, the punching cylinder 411 can be controlled to retract, so as to drive the punch 412 to return to its original position.

[0045] Among them, see Figure 3 and Figure 7 Optionally, the pressure block 425 is provided with a punching hole 426 on the side facing the bending forming cavity 21. After the pressure block 425 presses and fixes the corresponding position of the bent trim 82, the punching hole 426 of the pressure block 425 corresponds to the template hole 22. In this way, when the punch 412 extends into the template hole 22 to punch the bent trim 82, the punch 412 will bring the punched material into the punching hole 426 of the pressure block 425. The punching hole 426 can be a through hole, and the punched material can be pushed out through the punching hole 426 of the pressure block 425.

[0046] See Figure 10-11 Optionally, the template support 3 includes a first vertical plate 31, a second vertical plate 32, a first support block 33, a first screw 34, and a first locking bolt 35. The bottom end of the first vertical plate 31 is connected to the base plate 1. The first vertical plate 31 is provided with a first vertical waist-shaped hole 311. The first support block 33 is fixed to one side of the first vertical plate 31 and is lower than the first vertical waist-shaped hole 311. The first screw 34 is threadedly connected to the first support block 33. The second vertical plate 32 is located on one side of the first vertical plate 31, and the bottom end of the second vertical plate 32 abuts against the top end of the first screw 34. The top end of the second vertical plate 32 is supported on the bent template 2. The first locking bolt 35 is sequentially inserted into the first vertical waist-shaped hole 311 and the second vertical plate 32.

[0047] In this embodiment, the template support 3 has the function of fine-tuning the height of the bending and forming template 2, so that the bending and forming template 2 can better adapt to the external clamping mechanism 9 and the punching device 4. Specifically, when it is necessary to adjust the height of the bending and forming template 2, the first locking bolt 35 can be loosened first, and then the second vertical plate 32 can be moved upward, which will also drive the first locking bolt 35 to move upward in the first vertical slot 311 of the first vertical plate 31. After the height position of the second vertical plate 32 is adjusted, the first locking bolt 35 can be locked at the first vertical plate 31, so that the height of the second vertical plate 32 is locked. In addition, in order to further maintain the second vertical plate 32 at the adjusted height position, the first screw 34 can be turned so that the first screw 34 moves upward relative to the first support until the top of the first screw 34 abuts against the second vertical plate 32.

[0048] See Figure 10-11Optionally, the template support 3 further includes a second support block 36 and a rear top rod 37. The second support block 36 is disposed on the top of the second vertical plate 32. The second vertical plate 32 vertically supports the bending and forming template 2 through the second support block 36. An extension block 361 is provided protruding upward from the rear end of the second support block 36. The rear top rod 37 is threadedly connected to the extension block 361 and abuts against the rear side of the bending and forming template 2.

[0049] In this embodiment, the second vertical plate 32 can vertically support the bending template 2 via the second support block 36. In addition, the rear end of the second support block 36 has an extension block 361 protruding upwards, which can be turned to make the rear push rod 37 abut against the rear side of the bending template 2, thus supporting the rear side of the bending template 2. That is, the template support 3 can both vertically support the bending template 2 and support it from the rear. Since the external clamping mechanism 9 drives the straight trim 81 to move backwards and form it into a curved trim 82 within the bending cavity 21, the bending template 2 will be subjected to a force from front to back. With the rear push rod 37 supporting the bending template 2 from the rear, the bending template 2 can be made more stable.

[0050] Optionally, multiple template supports 3 are provided, and the multiple template supports 3 are arranged sequentially along the extension direction of the bending and forming template 2 to further improve the stability of the bending and forming template 2.

[0051] See Figure 1 , Figure 6-7 Optionally, the integrated mold for bending and punching trim strips also includes two stripping mechanisms 6, which are respectively disposed at both ends of the bending forming template 2 in the extension direction. Each stripping mechanism 6 includes a stripping support plate 62, a stripping cylinder 61, and a stripping push plate 63. The stripping cylinder 61 is connected to the end of the bending forming template 2 through the stripping support plate 62, and the piston rod of the stripping cylinder 61 is connected to the stripping push plate 63. The stripping cylinder 61 is used to extend so that the stripping push plate 63 pushes out the bent trim strip 82 in the bending forming cavity 21.

[0052] In this embodiment, after punching the curved trim 82, the clamping mechanism 42 can be controlled to change to an avoidance state first. Then, the stripping cylinder 61 can be controlled to extend, and the punched curved trim can be pushed forward from the bending forming cavity 21 by the stripping push plate 63.

[0053] See Figure 1 , Figure 6 and Figure 10Optionally, the integrated mold for bending and punching decorative strips also includes multiple receiving racks 7, which are arranged sequentially on the front side of the bending forming template 2 along the extension direction of the bending forming template 2. Each receiving rack 7 includes a vertical telescopic rod 71 and a receiving rod 72. The bottom end of the vertical telescopic rod 71 is fixed to the base plate 1, and the receiving rod 72 is fixed to the top of the vertical telescopic rod 71. One end of the receiving rod 72 abuts against the front side of the bending forming template 2 and is lower than the bending forming cavity 21. The other end of the receiving rod 72 is gradually inclined downward, and the other end of the receiving rod 72 is bent upward to form a stop rod 721.

[0054] In this embodiment, as described above, after punching the curved trim 82, the clamping mechanism 42 can be controlled to change to an avoidance state. Then, the stripping cylinder 61 is controlled to extend, and the punched curved trim is pushed forward from the bending forming cavity 21 by the stripping push plate 63. The forward-pushed curved trim 82 will naturally fall on the receiving rod 72 of the receiving rack 7. Then, the curved trim 82 will slide forward and downward along the inclined direction of the receiving rod 72 under gravity until it is blocked by the stop rod 721. After the receiving rack 7 receives one or more punched curved trims 82, they can be collected together.

[0055] The vertical telescopic rod 71 of the receiving frame 7 can drive the receiving rod 72 to make fine-tuning adjustments in height to adapt to the height of the bending forming template 2. Multiple receiving frames 7 can be provided, and multiple receiving frames 7 are arranged sequentially along the extension direction of the bending forming template 2, so that multiple receiving rods 72 of multiple receiving frames 7 can receive materials together.

[0056] See Figure 3 and Figure 5 Optionally, the punching bracket 5 includes a first support plate 51, a second support plate 52, a hinge shaft 53, and a second locking bolt 54. The bottom end of the first support plate 51 is connected to the base plate 1. The first support plate 51 is provided with an arc-shaped waist-shaped hole 511. The second support plate 52 is located on one side of the first support plate 51 and the two are perpendicular to each other. The second support plate 52 is hinged to the first support plate 51 through the hinge shaft 53. The thickness direction of the first support plate 51 is parallel to the tangent direction of the corresponding position of the bending forming template 2. The axial direction of the hinge shaft 53 is parallel to the thickness direction of the first support plate 51. The center of the arc-shaped waist-shaped hole 511 is coaxial with the hinge shaft 53. The second locking bolt 54 is sequentially inserted into the arc-shaped waist-shaped hole 511 and the second support plate 52. The second support plate 52 is connected to the punching device 4.

[0057] In this embodiment, the second support plate 52 is hinged to the first support plate 51 via the hinge shaft 53. Therefore, the second support plate 52 can drive the entire punching device 4 to rotate around the axis of the hinge shaft 53 to adjust the angle of the punching device 4. This facilitates the matching and alignment of the punching mechanism 41 with the template hole 22 of the bending forming template 2, and also facilitates the pressure block 425 of the pressing mechanism 42 to enter the bending forming cavity 21 and press and fix the bent trim 82 at a suitable angle. When the second support plate 52 drives the punching device 4 to rotate, since the center of the arc-shaped waist-shaped hole 511 is coaxial with the hinge shaft 53, the unlocked second locking bolt 54 will also move in the arc-shaped waist-shaped hole 511. After the second support plate 52 drives the punching device 4 to adjust the angle, the second locking bolt 54 is locked, thus maintaining the current angle between the second support plate 52 and the punching device 4.

[0058] See Figure 3 and Figure 5 Optionally, the punching bracket 5 further includes a third support block 55, a guide rod 56, and a third locking bolt 57.

The bottom end of the first support plate 51 is bent to form a first bent portion 512 that fits against the base plate 1. The first bent portion 512 is guided and cooperates with the guide rod 56. The first bent portion 512 is provided with a first horizontal waist-shaped hole 513. The extension direction of the first horizontal waist-shaped hole 513 is perpendicular to the tangent direction of the corresponding position of the bending forming template 2. The third locking bolt 57 is sequentially inserted into the first horizontal waist-shaped hole 513 and the base plate 1.

[0059] The extension direction of the first horizontal waist-shaped hole 513 is perpendicular to the tangent direction of the corresponding position of the bending forming template 2. In other words, the extension of the first horizontal waist-shaped hole 513 is parallel to the normal of the corresponding position of the bending forming template 2. The extension and retraction directions of the aforementioned clamping cylinder 421 and punching cylinder 411 are also parallel to the normal of the corresponding position of the bending forming template 2.

[0060] In this embodiment, the punching bracket 5 can also adjust the position of the punching device 4 in the normal direction of the bending forming template 2. Specifically, first, the third locking bolt 57 is loosened, and then the first support plate 51 drives the second support plate 52 and the punching device 4 to move relative to the third locking bolt 57. During the movement, the stability of the movement can be ensured by the guiding action of the guide rod 56, and no deviation will occur. After moving into place, the third locking bolt 57 is locked onto the first bending part 512.

[0061] See Figure 3 and Figure 5Optionally, the punching bracket 5 further includes a third support plate 58 and a fourth locking bolt 59. The second support plate 52 is connected to the punching mechanism 41 through the third support plate 58. The second support plate 52 is provided with a second oblong hole 521.

The fourth locking bolt 59 is inserted into the second oblong hole 521 and the third support plate 58 in sequence. The top of the third support plate 58 is connected to the punching mechanism 41.

[0062] In this embodiment, the punching bracket 5 can also adjust the height of the punching device 4. Specifically, first loosen the fourth locking bolt 59, then move the third support plate 58 and the punching device 4 up and down along the extension direction of the second waist-shaped hole 521 to adjust the height of the punching device 4. After the height is adjusted, tighten the fourth locking bolt 59 on the second support plate 52 to maintain the adjusted height of the punching device 4.

[0063] See Figure 3 Optionally, the punching bracket 5 further includes a fourth support plate 510 and a second screw 5102. The bottom end of the fourth support plate 510 is connected to the base plate 1, and the top end of the fourth support plate 510 is provided with a horizontal part 5101. The second screw 5102 is threaded to the horizontal part 5101, and the top end of the second screw 5102 abuts against the punching mechanism 41.

[0064] In this embodiment, the top of the fourth support plate 510 is provided with a horizontal part 5101, and a second screw 5102 threadedly connected to the horizontal part 5101 is inserted therein. Thus, the height can be adjusted by turning the second screw 5102 until the top of the second screw 5102 abuts against the punching mechanism 41. The top of the aforementioned third support plate 58 can be connected and fixed to the cylinder body of the punching cylinder 411 and the clamping cylinder 421, while the top of the second screw 5102 can abut against the bottom of the sleeve 422 of the clamping mechanism 42, so as to further improve the stability of the clamping mechanism 42 and even the entire punching device 4.
