[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 8 A metal decorative part side folding tooling includes a first mounting base 7, a second mounting base 8, a first folding block 4, a second folding block 5, a displacement driving device 6, and a limiting device 3 for fixing the metal decorative part 9. The first mounting base 7 and the second mounting base 8 are distributed on the side of the limiting device 3. The first folding block 4 is movably and self-resettingly mounted on the first mounting base 7, and the second folding block 5 is movably and self-resettingly mounted on the second mounting base 8. The moving direction of the first folding block 4 and the moving direction of the second folding block 5 are both towards or away from the limiting device 3. The first folding block 4 is used to bend the corner edge of the metal decorative part 9 when moving, and the second folding block 5 is used to bend the long side edge of the metal decorative part 9 when moving. The displacement driving device 6 is provided with a first push block 1 opposite to the first folding block 4 and a second push block 2 opposite to the second folding block 5. The displacement driving device 6 is used to control the first folding block 4 and the second folding block 5 to move toward the limiting device 3 in sequence through the first push block 1 and the second push block 2.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: the metal decorative part 9 is fixed by the limiting device 3, and then the displacement driving device 6 pushes the first folding block and the second folding block 5 in turn through the first push block 1 and the second push block 2. After the first folding block 4 bends the corner edge, it exits by relying on the self-resetting function. At the same time, the second folding block 5 bends the long side edge, so as to realize the integration of the folding operation for different parts of the same metal decorative part 9 into one tooling, reduce the phenomenon of multi-process folding, improve the overall folding effect of the metal decorative part 9 after folding in different parts, improve production efficiency, and avoid the appearance defects of the metal decorative part 9.

[0021] Furthermore, the first push block 1 is provided with a relief groove 13 and a pressing part 11 distributed along the first straight line direction; The first folded edge block 4 has a first inclined surface 12 at one end away from the limiting device 3, and the pressing part 11 has a second inclined surface 41 that is adapted to the first inclined surface 12; The displacement driving device 6 is used to control the first pusher 1 to move along the first straight line direction; When the first push block 1 moves along the first straight direction, the first inclined surface 12 of the pressing part 11 slides and rubs against the second inclined surface 41. The clearance groove 13 is located on the side of the first push block 1 near the second inclined surface 41, and the clearance groove 13 is used to accommodate the end of the first folded block 4 away from the limiting device 3.

[0022] As can be seen from the above description, through the setting of the relief groove 13 and the pressing part 11 on the first push block 1, and the first inclined surface 12 and the second inclined surface 41 adapted on the first folding block 4 and the pressing part 11, when the displacement driving device 6 drives the first push block 1 to move along the first straight direction, the sliding friction between the inclined surfaces can smoothly convert the linear motion of the first push block 1 into the motion of the first folding block 4 approaching the limiting device 3, realizing the effective transmission of force and direction conversion; while the relief groove 13 can accommodate the end of the first folding block 4 when the first push block 1 moves to a specific position, avoiding mechanical interference between the two, ensuring that the first folding block 4 can smoothly exit by relying on the self-resetting function after completing the folding, ensuring the continuity and stability of the folding action.

[0023] Furthermore, it also includes a third inclined surface 14, wherein the first inclined surface 12 and the third inclined surface 14 are located on opposite sides of the end of the first folded block 4 away from the limiting device 3; The groove 13 has a fourth inclined surface 42 on the side of the groove near the pressing part 11, which is adapted to the third inclined surface 14. The fourth inclined surface 42 is inclined toward the bottom of the groove 13.

[0024] As can be seen from the above description, the first inclined surface 12 and the third inclined surface 14, which are arranged opposite each other on the first folding block 4, together with the fourth inclined surface 42 at the opening of the clearance groove 13, can not only achieve precise advancement of the first folding block 4 through the cooperation of the first and second inclined surfaces during the movement of the first push block 1, but also, when the first push block 1 retracts or the first folding block 4 resets, with the help of the matching guidance of the third inclined surface 14 and the fourth inclined surface 42, make the end of the first folding block 4 enter or exit the clearance groove 13 more smoothly, further optimizing the smoothness of the forward and backward movement of the first folding block 4.

[0025] Furthermore, the first mounting base 7 includes a base 71, a slider 72, and an elastic connecting assembly; The base 71 is provided with a guide surface 75 for the slider 72 to slide towards or away from the limiting device 3. One end of the elastic connecting component is connected to the slider 72, and the other end of the elastic connecting component is disposed on the base 71. The first folding block 4 is disposed on the slider 72.

[0026] As can be seen from the above description, the first mounting base 7 provides precise sliding guidance for the slider 72 through the guide surface 75 of the base 71, ensuring that the first folding block 4 can only move in the direction of approaching or moving away from the limiting device 3, avoiding deviation during the folding process and ensuring folding accuracy; the elastic connecting component provides self-resetting power for the slider 72, so that it can automatically return to the initial position when it is not subjected to the force of the first push block 1, without the need for additional manual operation, simplifying the operation process of the tooling, improving the degree of automation, and providing a reliable guarantee for continuous folding operation.

[0027] Furthermore, the elastic connection assembly includes a spring 73 and a baffle 74; The baffle 74 is disposed on the side of the guide surface 75 near the limiting device 3, and the two ends of the spring 73 are respectively connected to the baffle 74 and the slider 72.

[0028] As can be seen from the above description, the elastic connection assembly adopts the structure of spring 73 and baffle 74. The baffle 74 is fixed on the guide surface 75 near the limiting device 3, providing a stable force support point for spring 73 and ensuring that the elastic force direction of spring 73 is always consistent with the sliding direction of slider 72. The elastic force of spring 73 can be evenly applied to slider 72, making the reset process of the first folded block 4 smooth and controllable, avoiding over-reset or under-reset, and ensuring that the initial position of the first folded block 4 is consistent after each reset.

[0029] Furthermore, the first folded edge block 4 is provided with a contour-fitting limiting groove 43 for adapting to the corner edge at one end near the limiting device 3.

[0030] As can be seen from the above description, the first folding block 4 is provided with a contouring limiting groove 43 at one end near the limiting device 3. This groove can precisely match the corner edge of the metal decorative part 9, and play a role in pre-positioning and restraining the corner edge during the folding process, preventing the corner edge from shifting or deforming when bending, ensuring accurate folding angle and regular shape, improving the folding quality and consistency of the corner edge, reducing product scrap due to folding misalignment, and further ensuring the appearance and dimensional accuracy of the metal decorative part 9.

[0031] Furthermore, the limiting device 3 includes a support member 31, a pressure plate 32, and a downward pressure drive assembly; Both the first mounting base 7 and the second mounting base 8 are adjacent to the support member 31, which is used to support the metal decorative part 9; The movable end of the pressure drive assembly corresponds vertically to the support member 31, and the pressure plate 32 is disposed at the movable end of the pressure drive assembly.

[0032] As can be seen from the above description, the limiting device 3 provides stable support for the metal decorative part 9 through the support member 31. In conjunction with the downward pressure drive component, it drives the pressure plate 32 to move downward, which can firmly press the metal decorative part 9 onto the support member 31, preventing the metal decorative part 9 from shifting due to force during the folding process and ensuring accurate folding position. The vertically corresponding arrangement of the pressure plate 32 and the support member 31 can make the pressure on the metal decorative part 9 more uniform, prevent deformation or damage caused by excessive local force, and improve the reliability of fixing the metal decorative part 9.

[0033] Furthermore, the pressure drive assembly includes a guide post 33, a mounting plate 34, and a pressure drive component 35; The mounting plate 34 is mounted on the support member 31 via the guide post 33, and the pressing drive member 35 is disposed on the mounting plate 34, with the movable end of the pressing drive member 35 facing the support member 31. The pressure plate 32 is sleeved on the guide post 33, and the pressure plate 32 is connected to the movable end of the pressing drive member 35.

[0034] As described above, in the pressing drive assembly, the guide post 33 provides guidance for the up-and-down movement of the pressure plate 32, ensuring that the pressure plate 32 always corresponds vertically with the support member 31, and avoiding pressure deviation; the mounting plate 34 is stably mounted above the support member 31 through the guide post 33, providing a solid mounting base for the pressing drive 35; the pressing drive 35 drives the pressure plate 32 to move, which can accurately control the pressing force and stroke, and can adapt to metal decorative parts 9 of different thicknesses or materials. It can not only ensure the pressing effect, but also avoid appearance defects caused by excessive extrusion, thus improving the adaptability and pressing stability of the limiting device 3.

[0035] Furthermore, the displacement driving device 6 includes a tooling table 61, an upper mold 62, and a support column 63; The first mounting base 7, the second mounting base 8, and the limiting device 3 are all located on the tooling table 61, and the upper mold 62 is supported above the tooling table 61 by at least two support columns 63; The first push block 1 and the second push block 2 are located on the side of the upper mold 62 facing the first mounting base 7 and the second mounting base 8, and the height of the support column 63 is adjustable.

[0036] As can be seen from the above description, the tooling table 61 of the displacement driving device 6 provides a unified installation reference for the first mounting base 7, the second mounting base 8 and the limiting device 3, ensuring the relative position accuracy of each component and providing a basis for the accuracy of the bending operation; the upper mold 62 integrates the first push block 1 and the second push block 2, which facilitates the coordinated action of the two through the same driving source; the height of the support column 63 is adjustable, so that the distance between the upper mold 62 and the tooling table 61 can be adjusted according to the component movement distance required for bending.

[0037] Furthermore, the support column 63 is a lifting cylinder, which is mounted on the tooling table 61, and the movable end of the lifting cylinder is connected to the upper mold 62.

[0038] As can be seen from the above description, the support column 63 adopts a lifting cylinder, whose movable end is directly connected to the upper mold 62. It can quickly and stably drive the upper mold 62 to rise and fall. The response speed is fast and the driving force is controllable. It can accurately control the moving distance and speed of the first push block 1 and the second push block 2, ensuring that the two push the first and second folding parts in a preset order and force, thus improving the automation control accuracy of the folding process.

[0039] Please refer to Figures 1 to 8 Embodiment 1 of this utility model is as follows: A side-folding fixture for a metal decorative part includes a first mounting base 7, a second mounting base 8, a first folding block 4, a second folding block 5, a displacement driving device 6, and a limiting device 3 for fixing the metal decorative part 9. The first mounting base 7 and the second mounting base 8 are distributed around the side of the limiting device 3. The first folding block 4 is movably and self-resettingly mounted on the first mounting base 7, and the second folding block 5 is movably and self-resettingly mounted on the second mounting base 8. The moving direction of the first folding block 4 and the moving direction of the second folding block 5 are both towards or away from the limiting device 3. The first folding block 4 is used to bend the corner edge of the metal decorative part 9 when moving, and the second folding block 5 is used to bend the long side edge of the metal decorative part 9 when moving. The displacement driving device 6 is provided with a first push block 1 opposite to the first folding block 4 and a second push block 2 opposite to the second folding block 5. The displacement driving device 6 is used to control the first folding block 4 and the second folding block 5 to move towards the limiting device 3 in sequence through the first push block 1 and the second push block 2.

[0040] In this embodiment, as Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, the first push block 1 is provided with a relief groove 13 and a pressing part 11 distributed along the first straight line direction; the first folded edge block 4 is provided with a first inclined surface 12 at the end away from the limiting device 3, and the pressing part 11 is provided with a second inclined surface 41 adapted to the first inclined surface 12; the displacement driving device 6 is used to control the first push block 1 to move along the first straight line direction; when the first push block 1 moves along the first straight line direction, the first inclined surface 12 of the pressing part 11 slides and rubs against the second inclined surface 41; the relief groove 13 is located on the side of the first push block 1 close to the second inclined surface 41, and the relief groove 13 is used to accommodate the end of the first folded edge block 4 away from the limiting device 3.

[0041] Taking the first straight line as vertically downward as an example, combined with Figure 4 and Figure 5 As shown, the operation process of a side folding fixture for a metal decorative part is as follows: First, before the displacement driving device 6 simultaneously controls the first push block 1 and the second push block 2 to descend, by adjusting the distance between the first push block 1 and the first folding block 4, the distance between the second push block 2 and the second folding block, or the distance between the first folding block 4 and the corner edge of the metal decorative part 9, and the distance between the second folding block 55 and the long side edge of the metal decorative part 9, after the displacement driving device 6 simultaneously controls the first push block 1 and the second push block 2 to descend, the first push block 1 first contacts the first folding block 4 and pushes the first folding block 4 to press against the corner edge of the metal decorative part 9, thus completing the bending.

[0042] In this process, the first inclined surface 12 on the pressing part 11 of the first push block 1 abuts against the second inclined surface 41 of the first folding block 4. The sliding friction between the inclined surfaces can smoothly transform the linear motion of the first push block 1 into the motion of the first folding block 4 approaching the limiting device 3. Relying on the guiding effect of the first mounting seat 7, the first folding block 4 approaches the corner edge of the metal decorative part 9 obliquely downward, and then presses against it and bends it downward.

[0043] Then, the displacement drive device 6 continues to control the first push block 1 and the second push block 2 to descend. At this time, the first push block 1 continues to move down, so that the first inclined surface 12 of the pressing part 11 is separated from the second inclined surface 41 of the first folding block 4, so that the end of the first folding block 4 away from the limiting device 3 corresponds to the relief groove 13. Under the relief space provided by the relief groove 13 and the self-resetting function of the first folding block 4, the first folding block 4 that was originally pushed begins to reset and enters the relief groove 13, that is, the corner edge of the first folding block 4 away from the metal decorative strip. At the same time, as the second push block 2 descends, the second push block 2 pushes the second folding block 5 to move towards the long side of the metal decorative strip, pressing and bending the long side.

[0044] Moreover, combined Figure 5 , Figure 7 as well as Figure 8 As shown, the first folded edge block 4 also includes a third inclined surface 14. The first inclined surface 12 and the third inclined surface 14 are located on opposite sides of the end of the first folded edge block 4 away from the limiting device 3. The groove opening of the clearance groove 13 is provided with a fourth inclined surface 42 that is adapted to the third inclined surface 14 on the side of the groove close to the pressing part 11. The fourth inclined surface 42 is inclined toward the bottom of the clearance groove 13.

[0045] After the second folding block 55 completes the bending action, the displacement driving device 6 controls the first push block 1 and the second push block 2 to rise. At this time, the third inclined surface 14 of the clearance groove 13 slides and rubs against the fourth inclined surface 42 at the bottom of the first folding block 4. The sliding friction between the inclined surfaces is used to smoothly convert the linear motion of the first push block 1 into the motion of the first folding block 4 approaching the limiting device 3, so that the first push block 1 can smoothly exit from the first mounting base 7. The first folding block 4 and the second folding block 55 are reset using the self-resetting function, waiting for the bending operation of the next metal decorative strip.

[0046] In this embodiment, as Figure 6 As shown, the first folding block 4 has a contouring limiting groove 43 for adapting to the corner edge on one end near the limiting device 3. In other equivalent embodiments, the contouring limiting groove 43 can be provided on the accessory, and the accessory is detachably connected to the first folding block 4. By replacing the accessory with a different contouring limiting groove 43, the corner edge of the metal decorative strip with different shapes can be bent.

[0047] Please refer to Figure 4 and Figure 5 Embodiment two of this utility model is as follows: A metal decorative part side folding tooling, based on the above embodiment one, the first mounting base 7 includes a base 71, a slider 72 and an elastic connecting component; the base 71 is provided with a guide surface 75 for the slider 72 to slide in the direction of approaching or moving away from the limiting device 3, one end of the elastic connecting component is connected to the slider 72, and the other end of the elastic connecting component is disposed on the base 71; the first folding block 4 is disposed on the slider 72.

[0048] The elastic connection assembly includes a spring 73 and a baffle 74. The baffle 74 is located on the guide surface 75 near the limiting device 3, and the two ends of the spring 73 are connected to the baffle 74 and the slider 72, respectively. When the first folding block 4 is pushed, the spring 73 is also compressed, and the elastic potential energy stored in the spring 73 pushes the first folding block 4 back, achieving self-resetting. The self-resetting function of the second folding block 55 can also be achieved using components such as the spring 73. To improve the elastic strength, the spring 73 is preferably a steel spring 73.

[0049] Please refer to Figure 3 and Figure 6 Embodiment three of this utility model is as follows: A side folding tooling for a metal decorative part, based on the above embodiment one or two, includes a limiting device 3 comprising a support member 31, a pressure plate 32, and a pressing drive assembly; the first mounting base 7 and the second mounting base 8 are both adjacent to the support member 31, and the support member 31 is used to support the metal decorative part 9; the movable end of the pressing drive assembly corresponds vertically to the support member 31, and the pressure plate 32 is disposed at the movable end of the pressing drive assembly.

The pressure plate 32 is sleeved on the guide post 33 and is connected to the movable end of the pressing drive component 35.

[0051] In this embodiment, after the metal decorative strip is placed on the support member 31, the pressing drive member 35 is controlled to move, so that the pressure plate 32 moves down along the guide post 33 and presses onto the metal decorative strip.

[0052] Please refer to Figure 1 Embodiment four of this utility model is as follows: A side-folding fixture for a metal decorative part, based on embodiments one, two, or three above, includes a displacement driving device 6 comprising a fixture table 61, an upper mold 62, and support columns 63; a first mounting base 7, a second mounting base 8, and a limiting device 3 are all located on the fixture table 61, and the upper mold 62 is supported above the fixture table 61 by at least two support columns 63; a first push block 1 and a second push block 2 are located on the side of the upper mold 62 facing the first mounting base 7 and the second mounting base 8, and the height of the support columns 63 is adjustable. Optionally, the support column 63 is a lifting cylinder, which is mounted on the fixture table 61, and the movable end of the lifting cylinder is connected to the upper mold 62.

[0053] In this embodiment, multiple support columns 63 work together to control the upper mold 62 to descend, so that the first push block 1 presses against the first folding block 4 and the second push block 2 presses against the second folding block 55.

After the first folding block bends the corner edge, it retracts by relying on its self-resetting function, while the second folding block bends the long side edge. This integrates the folding operations for different parts of the same type of metal decorative part into one fixture, reduces the phenomenon of multi-process folding, improves the overall folding effect of the metal decorative part after folding at different parts, increases production efficiency, and avoids appearance defects in the metal decorative part. Regarding the movement of the folding block, through the setting of the clearance groove and the pressing part on the first push block, and the matching first and second inclined surfaces on the first folding block and the pressing part, when the displacement driving device drives the first push block to move along the first straight line direction, the sliding friction between the inclined surfaces can smoothly transform the linear motion of the first push block into the motion of the first folding block approaching the limiting device, realizing the effective transmission of force and direction conversion; in addition, the limiting device provides stable support for the metal decorative part through the support member, and in conjunction with the downward pressing drive component to drive the pressure plate to move downward, it can firmly press the metal decorative part onto the support member, avoiding displacement of the metal decorative part due to force during the folding process, and ensuring accurate folding position; the upper and lower corresponding setting of the pressure plate and the support member can make the pressure on the metal decorative part more uniform, prevent deformation or damage caused by excessive local force, and improve the reliability of fixing the metal decorative part.
