Description

Technical Field

[0001] This utility model relates to the field of stamping, and in particular to a stamping die for a decorative cover. Background Technology

[0002] In various fields of machinery, home appliances, and automotive parts, decorative covers are key components that combine protection and aesthetics. Their structural design and manufacturing process directly affect product performance and production efficiency. To meet the heat dissipation requirements of equipment, decorative covers are typically designed as covers with multiple ventilation holes. These holes not only provide ventilation and heat dissipation but also enhance the product's visual appeal through specific arrangements.

[0003] Currently, these decorative covers with ventilation holes are mostly made of metal sheets through a stamping process, which requires multiple steps such as punching and edge pressing. Since each step needs to be completed on different molds or equipment, the transitions and positioning adjustments between steps consume a significant amount of time, resulting in excessively long overall processing times and severely impacting production efficiency. Furthermore, multi-step processing can accumulate errors due to repeated positioning, reducing the dimensional accuracy and consistency of the product, making it difficult to meet the demands of high-volume, high-precision production. Utility Model Content

[0004] In order to improve processing efficiency and precision, this utility model provides a decorative cover stamping die.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] A decorative cover stamping die includes an upper die and a lower die. A hole pressing station, a punching station, an edge pressing station, and a grooving station are sequentially arranged between the upper die and the lower die. The lower die is provided with multiple sets of support columns for supporting materials. The support columns are distributed on both sides of the width direction of the lower die and are evenly distributed along the length direction of the lower die. The discharge end of the lower die is provided with a drive component for pulling the material to move along the length direction of the lower die.

[0007] After the upper and lower molds are closed, the upper mold drives the cutting tools in the hole pressing station, punching station, edge pressing station, and grooving station to move downwards for processing. The hole pressing station presses the edges around the vent holes of the current material. At the same time, the punching station, edge pressing station, and grooving station can simultaneously process the material from different stages in the previous process. After the driving component moves the material forward, each station switches the processing object in turn, always maintaining the simultaneous operation of multiple stations. Finally, the vent hole punching, edge pressing and shaping, and groove cutting are completed, realizing the integrated completion of multiple processes in the decorative cover processing.

[0008] The material moves continuously along the length of the lower die under the action of the driving component, eliminating the need for transfer between different molds or equipment. This significantly reduces process changeover and positioning adjustment time, greatly improving production efficiency. Simultaneously, the integration of multiple workstations into a single mold reduces cumulative errors caused by repeated positioning, effectively ensuring product dimensional accuracy and consistency, and meeting the demands of high-volume, high-precision production. The support columns on both sides of the lower die are evenly distributed along the length, providing stable support for material movement, preventing material deformation during processing, and further guaranteeing product quality.

[0009] Preferably, the hole pressing station includes a first hole edge position and a second hole edge position. The decorative cover is provided with multiple rows of heat dissipation holes. The first hole edge position is set to the odd-numbered rows of holes on the decorative cover, and the second hole edge position is set to the even-numbered rows of holes on the decorative cover. The first hole edge position and the second hole edge position are set sequentially along the length direction of the lower mold.

[0010] By separating the first and second hole edges, the layout density of the single-pass punching device is reduced. After the upper and lower molds are closed, the first hole edge presses the edge of the odd-numbered hole positions while other stations work simultaneously. As the material moves forward, the second hole edge presses the edge of the even-numbered hole positions. Each station switches the processing object in turn, continuously maintaining the simultaneous operation of multiple stations to complete subsequent punching, edge pressing, and grooving, achieving continuous and efficient processing.

[0011] Preferably, the first hole edge includes a first cutting tool disposed on the upper mold and a first support portion disposed on the lower mold, the first support portion having a clearance hole for avoiding the first cutting tool; the second hole edge includes a second cutting tool disposed on the upper mold and a second support portion disposed on the lower mold, the second support portion having a clearance hole for avoiding the second cutting tool.

[0012] The clearance holes in the first and second supports provide space for the first and second cutting tools to operate, preventing damage from collisions between the tools and the supports and ensuring stable operation of the edge-pressing process. At the same time, they ensure that the cutting tools can accurately act around the hole positions, improving edge-pressing accuracy. Combined with the separately positioned hole edges, this further enhances production efficiency and product quality.

[0013] Preferably, the support column has a limiting groove on its peripheral wall for supporting the material. The number of support columns in each group is 2. The two support columns in the same group are arranged opposite each other on both sides of the lower mold. The distance between the peripheral walls of the limiting grooves of the two support columns is equal to the width of the material.

[0014] The limiting grooves of the support columns are adapted to the width of the material, stably clamping it from both sides and preventing displacement or shaking during processing due to force. The symmetrical arrangement of the support columns in the same group ensures accurate material positioning, and together with the evenly distributed support structure, further improves processing stability, ensures product dimensional accuracy, and facilitates efficient production.

[0015] Preferably, the edge pressing station includes a pressing die on the upper die and a third support portion on the lower die, wherein the third support portion has a groove adapted to the shape of the pressing die.

[0016] Metal is malleable, and the die at the edge pressing station is shaped to fit the groove of the third support, precisely conforming to the material edge and ensuring uniform pressing force. This not only prevents material edge deformation during processing, ensuring pressing accuracy, but also enhances operational stability and, in conjunction with other stations, further improves product quality.

[0017] Preferably, the edge pressing station further includes a return ejector station, the ejector station being provided with ejector columns, and the ejector columns being provided with two columns.

[0018] The ejection position is set to push the pressed-down product back to a position flush with the material, facilitating the next step of unloading.

[0019] Preferably, the grooving station includes a bending section and a pressing section on the upper mold, and the lower mold is provided with a forming section. The bending section cooperates with the forming section to press the bottom wall of the cover into an arc-shaped surface, and the pressing section is used to assist in forming the peripheral wall of the cover.

[0020] Preferably, the upper mold is provided with multiple guide posts, and the lower mold is provided with multiple positioning holes that are directly opposite the guide posts.

[0021] In summary, this utility model has the following beneficial technical effects:

[0022] After the upper and lower molds are closed, the upper mold drives the cutting tools in the hole pressing station, punching station, edge pressing station, and grooving station to move downwards for processing. The hole pressing station presses the edges around the vent holes of the current material. At the same time, the punching station, edge pressing station, and grooving station can simultaneously process the material from different stages in the previous process. After the driving component moves the material forward, each station switches the processing object in turn, always maintaining the simultaneous operation of multiple stations. Finally, the vent hole punching, edge pressing and shaping, and groove cutting are completed, realizing the integrated completion of multiple processes in the decorative cover processing.

[0023] The material moves continuously along the length of the lower die under the action of the driving component, eliminating the need for transfer between different molds or equipment. This significantly reduces process changeover and positioning adjustment time, greatly improving production efficiency. Simultaneously, the integration of multiple workstations into a single mold reduces cumulative errors caused by repeated positioning, effectively ensuring product dimensional accuracy and consistency, and meeting the demands of high-volume, high-precision production. The support columns on both sides of the lower die are evenly distributed along the length, providing stable support for material movement, preventing material deformation during processing, and further guaranteeing product quality.

[0028] The following is in conjunction with the appendix Figure 1-3 This utility model will be described in further detail.

[0029] This utility model discloses a decorative cover stamping die.

[0030] Reference Figure 1 as well as Figure 2 A decorative cover stamping die includes an upper die 1 and a lower die 2. A hole pressing station, a punching station, an edge pressing station, and a grooving station are arranged sequentially between the upper die 1 and the lower die 2. The lower die 2 is provided with multiple sets of support columns 3 for supporting materials 4. The support columns 3 are distributed on both sides of the width direction of the lower die 2. The multiple sets of support columns 3 are evenly distributed along the length direction of the lower die 2. The discharge end of the lower die 2 is provided with a drive component for pulling the material 4 to move along the length direction of the lower die 2.

[0031] After the upper mold 1 and the lower mold 2 are closed, the upper mold 1 drives the cutting tools in the hole pressing station, punching station, edge pressing station and grooving station to move down for processing. The hole pressing station performs edge pressing treatment on the area around the vent hole of the current material 4. At the same time, the punching station, edge pressing station and grooving station can simultaneously work on the material 4 at different stages in the previous sequence. After the driving component moves the material 4 forward, each station switches the processing object in turn, always maintaining the simultaneous operation of multiple stations, and finally completing the vent hole punching, edge pressing and shaping and groove cutting, realizing the integrated completion of multiple processes of decorative cover processing.

[0032] Material 4 moves continuously along the length of the lower mold 2 under the action of the driving component, eliminating the need for transfer between different molds or equipment. This significantly shortens process changeover and positioning adjustment time, greatly improving production efficiency. Simultaneously, the integration of multiple workstations into the same mold reduces cumulative errors caused by multiple positioning operations, effectively ensuring product dimensional accuracy and consistency, and meeting the demands of high-volume, high-precision production. The support columns 3 on both sides of the lower mold 2 are evenly distributed along the length, providing stable support for the movement of material 4, preventing deformation of material 4 during processing, and further ensuring product quality.

[0033] Reference Figure 2 as well as Figure 3 In this embodiment, the hole pressing station includes a first hole edge position 5 and a second hole edge position 6. The decorative cover is provided with multiple rows of heat dissipation holes. The first hole edge position 5 is set to the odd-numbered rows of holes 7 on the decorative cover, and the second hole edge position 6 is set to the even-numbered rows of holes 7 on the decorative cover. The first hole edge position 5 and the second hole edge position 6 are set sequentially along the length direction of the lower mold 2.

[0034] The separate first and second hole edge positions 6 reduce the layout density of the single-pass punching device. After the upper mold 1 and lower mold 2 are closed, the first hole edge position 5 first presses the edge of the odd-numbered hole positions 7, while other stations work simultaneously; the material 4 moves forward, and the second hole edge position 6 then presses the edge of the even-numbered hole positions 7. Each station switches the processing object in turn, and multiple stations continue to operate simultaneously to complete the subsequent punching, edge pressing and grooving, and achieve continuous and efficient processing.

[0035] Reference Figure 2 as well as Figure 3 In this embodiment, the first hole edge 5 includes a first cutting tool 8 provided on the upper mold 1 and a first support part 9 provided on the lower mold 2. The first support part 9 is provided with a clearance hole 10 to avoid the first cutting tool 8. The second hole edge 6 includes a second cutting tool 11 provided on the upper mold 1 and a second support part 12 provided on the lower mold 2. The second support part 12 is provided with a clearance hole 10 to avoid the second cutting tool 11.

[0036] The clearance holes 10 of the first and second support parts 12 provide space for the first and second cutting tools 11 to operate, preventing the cutting tools from colliding and being damaged by the support parts, and ensuring the stable operation of the edge pressing process. At the same time, it ensures that the cutting tools can accurately act around the hole position 7, improving the edge pressing accuracy. In conjunction with the separately set hole edge positions, it further improves production efficiency and product quality.

[0037] Reference Figure 2 as well as Figure 3 In this embodiment, the peripheral wall of the support column 3 is provided with a limiting groove 13 for supporting the material 4. The number of each group of support columns 3 is 2. The two support columns 3 in the same group are arranged opposite each other on both sides of the lower mold 2. The distance between the peripheral walls of the limiting groove 13 of the two support columns 3 is equal to the width of the material 4.

[0038] The limiting groove 13 of the support column 3 is adapted to the width of the material 4, which can stably clamp the material 4 from both sides and prevent it from shifting or shaking due to force during processing. The symmetrical arrangement of the support columns 3 in the same group ensures accurate positioning of the material 4. Combined with the evenly distributed support structure, it further improves processing stability, ensures product dimensional accuracy, and helps to achieve efficient production.

[0039] Reference Figure 2 as well as Figure 3 In this embodiment, the edge pressing station includes a pressing die 14 disposed on the upper die 1 and a third support portion 15 disposed on the lower die 2. The third support portion 15 has a groove 16 that matches the shape of the pressing die 14.

[0040] Metal is malleable, and the shape of the die 14 at the edge pressing station is adapted to the groove 16 of the third support 15, which can precisely fit the edge of the material 4 and ensure uniform pressing force. This not only avoids deformation of the material 4 edge during processing and ensures pressing accuracy, but also enhances operational stability and, in conjunction with other stations, further improves product quality.

[0041] Reference Figure 2 as well as Figure 3 In this embodiment, the edge pressing station also includes a return ejection position 18, which is provided with ejection columns, and there are two ejection columns.

[0042] The ejection position 18 is set to push the pressed product back to a position flush with material 4, which facilitates the next step of unloading.

[0043] Reference Figure 2 as well as Figure 3 In this embodiment, the grooving station includes a bending part and a pressing part 19 provided on the upper mold 1, and a forming part 20 provided on the lower mold 2. The bending part cooperates with the forming part 20 to press the bottom wall of the cover into an arc-shaped surface, and the pressing part 19 is used to assist in forming the peripheral wall of the cover.

[0044] Reference Figure 2 as well as Figure 3 In this embodiment, the upper mold 1 is provided with multiple guide posts 21, and the lower mold 2 is provided with multiple positioning holes 17 that are directly opposite to the guide posts 21.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
