Description

Technical Field

[0001] This utility model relates to a composite processing mold. Background Technology

[0002] Traditional blanking dies for aluminum decorative parts can only complete the blanking process. If the sheet material needs to be punched, an additional punching die must be added, with the blanking die and punching die completing the blanking and punching processes separately. This leads to the following problems: First, two sets of dies are required for the two processes, significantly increasing the design and manufacturing costs of the dies. Second, transferring the sheet material from the blanking die to the punching die takes considerable time, resulting in a longer production cycle. Third, transferring the sheet material between different dies can easily cause reference deviations, especially for sheets with high hole position accuracy requirements, affecting the yield of finished products. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to modify the blanking die so that blanking and punching can be completed in one punching operation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A composite processing mold includes an upper cutting blade assembly and a concave module.

The concave module has a blanking boss that matches the blanking cutter, and the blanking boss is provided with a first through hole that matches the punching cutter; the blanking cutter and the blanking boss are used for blanking, and the punching cutter and the first through hole are used for punching.

[0005] In some embodiments, the composite processing mold further includes a pressure plate located above the concave module; the pressure plate matches the blanking boss, and the pressure plate has clearance holes corresponding to the punching cutter; the pressure plate can move up and down relative to the upper cutter assembly between a first position and a second position, wherein when the pressure plate is in the first position, the lower surface of the pressure plate is lower than the lower surface of the upper cutter assembly, and when the pressure plate is in the second position, the lower surface of the pressure plate is higher than the lower surface of the upper cutter assembly.

[0006] In some embodiments, the composite processing mold further includes an upper spring and an upper template, the upper cutting blade assembly and the pressure plate are located below the upper template, the upper cutting blade assembly is fixedly connected to the upper template, and the upper spring is disposed between the upper template and the pressure plate to reset the pressure plate from the second position to the first position.

[0007] In some embodiments, the composite processing mold further includes an upper limit stop and an upper fixing plate. The upper fixing plate is located between the upper template and the pressure plate. The upper limit stop is fixedly connected to the pressure plate and passes through the upper fixing plate. The upper fixing plate has a first limiting surface. The upper limit stop prevents the pressure plate from moving downward relative to the upper cutting blade assembly from the first position under the push of the upper spring by abutting against the first limiting surface.

[0008] In some embodiments, the composite processing mold further includes a lower template, a lower spring, and a plurality of lower lifting blocks. The concave module and the lower lifting blocks are located above the lower template, and the concave module is fixedly connected to the lower template. The lower lifting blocks can move up and down relative to the lower template between a third position and a fourth position. When the lower lifting block is in the third position, the upper surface of the lower lifting block is higher than the upper surface of the blanking boss. When the lower lifting block is in the fourth position, the upper surface of the lower lifting block is not higher than the upper surface of the blanking boss. The lower spring is disposed between the lower template and the lower lifting blocks and is used to reset the lower lifting blocks from the fourth position to the third position.

[0009] In some embodiments, the composite processing mold further includes a concave template, which is located between the lower template and the concave module; the concave module is provided with a first relief cavity, the concave template is provided with a second relief cavity, and a plurality of lower lifting blocks are evenly distributed, the lower lifting blocks being disposed in the first relief cavity or the second relief cavity.

[0010] In some embodiments, the composite processing mold further includes a lower limiting member, which is fixedly connected to the lower template. The lower limiting member passes through the lower lifting block, which has a second limiting surface. The lower limiting member abuts against the second limiting surface to prevent the lower lifting block from moving upward relative to the lower template from the third position under the push of the lower spring.

[0011] In some embodiments, the composite processing mold further includes an upper scrap cutter, a lower scrap cutter, and a scrap chute. The upper cutting blade assembly and the upper scrap cutter are arranged sequentially along the feeding direction of the composite processing mold. The concave module, the lower scrap cutter, and the scrap chute are arranged sequentially along the feeding direction. The upper scrap cutter and the lower scrap cutter are arranged opposite to each other.

[0012] In some embodiments, the composite processing mold further includes a waste box, a lower template, a lower pad, and a lower base plate. The concave module, the lower template, the lower pad, and the lower base plate are arranged sequentially from top to bottom. The lower template has a second through hole. The waste box is located between the lower template and the lower base plate. Punching waste passes through the first through hole and the second through hole in sequence and falls into the waste box.

[0013] In some embodiments, the composite processing mold further includes four guide blocks, with two guide blocks forming a group. The feeding direction of the composite processing mold is the length direction of the composite processing mold. The two groups of guide blocks are respectively located on both sides of the concave module along the length direction of the composite processing mold. The two guide blocks in the same group are arranged opposite to each other and are respectively located on both sides of the concave module along the width direction of the composite processing mold.

[0014] The beneficial effects of this utility model are as follows: As the upper cutting blade assembly moves downward relative to the concave module, the blanking cutter engages with the blanking boss to complete the blanking process. Simultaneously, the punching cutter inserts into the first through hole to complete the punching. Therefore, the composite processing mold provided by this utility model can complete both blanking and punching in a single punching operation. Attached Figure Description

[0017] 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.

[0018] Traditional blanking dies for aluminum decorative parts have an upper die with a groove and a lower die with a boss that matches the groove. As the upper die approaches the lower die, the boss inserts into the groove, completing the blanking process. A piece of material separates from the strip and remains on the boss. The piece is then transferred to a punching die. The upper die of the punching die has a protrusion, and the lower die has a through hole. As the upper die approaches the lower die, the protrusion inserts into the through hole, completing the punching process.

[0019] Please refer to Figure 1 and Figure 2 This utility model provides a composite processing mold, including an upper cutting blade assembly 1 and a concave module 2. Along the height direction Z of the composite processing mold, the upper cutting blade assembly 1 is located above the concave module 2. The upper cutting blade assembly 1 includes a punching cutter 11 and a blanking cutter 12 arranged around the punching cutter 11. The concave module 2 has a blanking boss 21 that matches the blanking cutter 12, and the blanking boss 21 has a first through hole 211 that matches the punching cutter 11. The blanking cutter 12 and the blanking boss 21 are used for blanking, and the punching cutter 11 and the first through hole 211 are used for punching.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: As the upper cutting blade assembly 1 moves downward relative to the concave module 2, the blanking cutter 12 engages with the blanking boss 21 to complete blanking. Simultaneously, the punching cutter 11 inserts into the first through hole 211 to complete punching. Therefore, the composite processing mold provided by this utility model can complete blanking and punching in one punching operation.

[0021] In some embodiments, the composite processing mold further includes a pressure plate 3, which is located above the concave module 2. The pressure plate 3 matches the blanking boss 21, and the pressure plate 3 has clearance holes corresponding to the punching cutter 11. The pressure plate 3 can move up and down relative to the upper cutter assembly 1 between a first position and a second position. When the pressure plate 3 is in the first position, the lower surface of the pressure plate 3 is lower than the lower surface of the upper cutter assembly 1; when the pressure plate 3 is in the second position, the lower surface of the pressure plate 3 is higher than the lower surface of the upper cutter assembly 1.

[0022] As can be seen from the above description, during the process of the upper template 4, the upper cutting blade assembly 1 and the pressure plate 3 moving downward relative to the concave module 2, the pressure plate 3 first contacts the material strip 50 on the dropping boss 21, presses down the material strip 50, and prevents the material strip 50 from moving during the punching process. Then, the upper cutting blade assembly 1 cooperates with the dropping boss 21 and the first through hole 211 to complete the dropping.

[0023] In some embodiments, please refer to Figure 1 and Figure 3 The composite processing mold also includes an upper spring 31 and an upper template 4. The upper cutter assembly 1 and the pressure plate 3 are located below the upper template 4. The upper cutter assembly 1 is fixedly connected to the upper template 4. The upper spring 31 is located between the upper template 4 and the pressure plate 3 and is used to reset the pressure plate 3 from the second position to the first position.

[0024] As can be seen from the above description, the automatic reset of the pressure plate 3 is achieved by setting the upper spring 31, which has a simple structure and low cost.

[0025] If necessary, the pressure plate 3 can also be reset in other ways.

[0026] In some embodiments, please refer to Figure 1 and Figure 3 The composite processing mold also includes an upper limit stop 32 and an upper fixing plate 5. The upper fixing plate 5 is located between the upper template 4 and the pressure plate 3. The upper limit stop 32 is fixedly connected to the pressure plate 3 and passes through the upper fixing plate 5. Please refer to [reference needed]. Figure 4 The upper fixed plate 5 has a first limiting surface 51. The upper limiting member 32 abuts against the first limiting surface 51 to prevent the pressure plate 3 from moving downward relative to the upper cutter assembly 1 under the push of the upper spring 31.

[0027] As can be seen from the above description, the upper limit member 32 limits the stroke of the pressure plate 3 under the push of the upper spring 31, resulting in a simple structure and low cost.

[0028] If necessary, the travel of the pressure plate 3 under the push of the upper spring 31 can also be limited by other means.

[0029] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 The composite processing mold also includes a lower template 6, a lower spring 71, and multiple lower lifting blocks 7. The recessed module 2 and the lower lifting blocks 7 are located above the lower template 6, and the recessed module 2 is fixedly connected to the lower template 6. The lower lifting blocks 7 can move up and down relative to the lower template 6 between a third position and a fourth position. When the lower lifting block 7 is in the third position, its upper surface is higher than the upper surface of the blanking boss 21. When the lower lifting block 7 is in the fourth position, its upper surface is not higher than the upper surface of the blanking boss 21. The lower spring 71 is located between the lower template 6 and the lower lifting blocks 7, and is used to reset the lower lifting blocks 7 from the fourth position to the third position.

[0030] As can be seen from the above description, after blanking and punching are completed, the upper die moves upward and the lower lifting block 7 moves upward and resets under the push of the lower spring 71, lifting the punched sheet and separating it from the blanking boss 21, so that the operator can take away the punched sheet.

[0031] In some embodiments, please refer to Figure 2 and Figure 5 The composite processing mold also includes a concave template 8, which is located between the lower template 6 and the concave module 2. The concave module 2 is provided with a first relief cavity, and the concave template 8 is provided with a second relief cavity. Multiple lower lifting blocks 7 are evenly distributed and are located in the first relief cavity or the second relief cavity.

[0032] As can be seen from the above description, evenly distributing the lower lifting blocks 7 helps to keep the material strip 50 flat.

[0033] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6 The composite processing mold also includes a lower limiting member 72, which is fixedly connected to the lower template 6. The lower limiting member 72 passes through the lower lifting block 7, which has a second limiting surface 73. The lower limiting member 72 abuts against the second limiting surface 73 to prevent the lower lifting block 7 from moving upward relative to the lower template 6 under the push of the lower spring 71.

[0034] As can be seen from the above description, the lower lifting block 7 is limited by the lower limit member 72 under the push of the lower spring 71, which has a simple structure and low cost.

[0035] If necessary, the travel of the lower lifting block 7 under the push of the lower spring 71 can also be limited by other means.

[0036] In some embodiments, please refer to Figure 1 and Figure 2The composite processing mold also includes an upper scrap cutter 91, a lower scrap cutter 92, and a scrap groove 93. The upper cutting blade assembly 1 and the upper scrap cutter 91 are arranged sequentially along the feeding direction of the composite processing mold. The concave module 2, the lower scrap cutter 92, and the scrap groove 93 are arranged sequentially along the feeding direction of the composite processing mold. The upper scrap cutter 91 and the lower scrap cutter 92 are arranged opposite to each other.

[0037] As can be seen from the above description, during blanking and punching, the upper waste cutter 91 and the lower waste cutter 92 work together to cut the waste generated during blanking into segments, which facilitates the collection of waste.

[0038] In some embodiments, please refer to Figure 2 and Figure 7 The composite processing mold also includes a waste box 94, a lower template 6, a lower pad 95, and a lower base plate 96. The concave module 2, the lower template 6, the lower pad 95, and the lower base plate 96 are arranged sequentially from top to bottom. The lower template 6 has a second through hole 61. The waste box 94 is located between the lower template 6 and the lower base plate 96. The punching waste passes through the first through hole 211 and the second through hole 61 in sequence and falls into the waste box 94.

[0039] As can be seen from the above description, the lower pad 95 and the lower base plate 96 form a space below the lower template 6 where the waste box 94 can be placed. The waste box 94 can be placed directly on the lower base plate 96, directly below the second through hole 61, to collect the waste generated by punching.

[0040] In some embodiments, please refer to Figure 2 and Figure 8 The composite processing mold also includes four guide blocks 10, with two guide blocks 10 forming a group. The feeding direction of the composite processing mold is the length direction X of the composite processing mold. The two groups of guide blocks 10 are located on both sides of the concave module 2 along the length direction X of the composite processing mold. The two guide blocks 10 in the same group are arranged opposite to each other and are located on both sides of the concave module 2 along the width direction Y of the composite processing mold.

[0041] As can be seen from the above description, the four guide blocks 10 can prevent the strip 50 from shifting along the width direction Y of the composite processing mold.

[0042] Please refer to Figures 1 to 7 One embodiment of this utility model is as follows: A composite machining mold, comprising an upper mold and a lower mold, please refer to... Figure 1 and Figure 2The upper die includes, from top to bottom, an upper template 4, an upper fixing plate 5, and an upper cutting blade assembly 1, and also includes a pressure plate 3 located below the upper fixing plate 5. The upper cutting blade assembly 1 includes a punching cutter 11 and a blanking cutter 12 arranged around the punching cutter 11. The lower die includes, from bottom to top, a lower base plate 96, a lower pad 95, a lower template 6, a concave template 8, and a concave module 2. The concave module 2 has a blanking boss 21 that matches the blanking cutter 12, and the blanking boss 21 has a first through hole 211 that matches the punching cutter 11. The blanking cutter 12 and the blanking boss 21 are used for blanking, and the punching cutter 11 and the first through hole 211 are used for punching. The pressure plate 3 matches the blanking boss 21, and the pressure plate 3 has a clearance hole corresponding to the punching cutter 11.

[0043] Please refer to Figure 1 The pressure plate 3 can move up and down relative to the upper cutter assembly 1 between a first position and a second position. When the pressure plate 3 is in the first position, its lower surface is lower than the lower surface of the upper cutter assembly 1; when the pressure plate 3 is in the second position, its lower surface is higher than the lower surface of the upper cutter assembly 1. An upper spring 31 is located between the upper template 4 and the pressure plate 3 to reset the pressure plate 3 from the second position to the first position. Please refer to... Figure 3 and Figure 4 The upper limit member 32 is fixedly connected to the pressure plate 3. The upper limit member 32 passes through the upper fixed plate 5. The upper fixed plate 5 has a first limiting surface 51. The upper limit member 32 abuts against the first limiting surface 51 to prevent the pressure plate 3 from moving downward relative to the upper cutter assembly 1 under the push of the upper spring 31.

[0044] Please refer to Figure 2 The recessed module 2 has multiple first clearance cavities, and the recessed template 8 has multiple second clearance cavities. A lower lifting block 7 is located within each of the first and second clearance cavities. The lower lifting block 7 can move up and down relative to the lower template 6 between a third position and a fourth position. When the lower lifting block 7 is in the third position, its upper surface is higher than the upper surface of the blanking boss 21. When the lower lifting block 7 is in the fourth position, its upper surface is not higher than the upper surface of the blanking boss 21. Please refer to... Figure 5 and Figure 6 A lower spring 71 is disposed between the lower template 6 and the lower lifting block 7, used to reset the lower lifting block 7 from the fourth position to the third position. A lower limiting member 72 is fixedly connected to the lower template 6 and passes through the lower lifting block 7. The lower lifting block 7 has a second limiting surface 73. The lower limiting member 72 abuts against the second limiting surface 73 to prevent the lower lifting block 7 from moving upward relative to the lower template 6 from the third position under the push of the lower spring 71.

[0045] Please refer to Figure 1 and Figure 2The upper mold also includes an upper scrap cutter 91, and the lower mold includes a scrap box 94, a lower scrap cutter 92, and a scrap chute 93. The upper cutting assembly 1 and the upper scrap cutter 91 are arranged sequentially along the feeding direction of the composite processing mold. The concave module 2, the lower scrap cutter 92, and the scrap chute 93 are arranged sequentially along the feeding direction of the composite processing mold. The upper scrap cutter 91 and the lower scrap cutter 92 are arranged opposite each other. Please refer to... Figure 7 The waste box 94 is located between the lower template 6 and the lower base plate 96. The lower template 6 has a second through hole 61, and the concave template 8 has a third through hole. The punching waste passes through the first through hole 211, the third through hole and the second through hole 61 in sequence and falls into the waste box 94.

[0046] Please refer to Figure 1 and Figure 2 The upper die also includes a feeding assembly 20, four upper guide assemblies 30a, and multiple upper limit posts 40a. The lower die also includes four guide blocks 10, multiple lower limit posts 40b, and four lower guide assemblies 30b. Two guide blocks 10 form a group. The feeding direction of this composite processing die is the length direction X of the die. The two groups of guide blocks 10 are located on both sides of the concave module 2 along the length direction X of the composite processing die. The two guide blocks 10 in the same group are arranged opposite each other, located on both sides of the concave module 2 along the width direction Y of the composite processing die. The feeding assembly 20 and the upper cutting assembly 1 are arranged sequentially along the feeding direction of the composite processing die. The four upper guide assemblies 30a are located at the four corners of the upper die, and the four lower guide assemblies 30b are located at the four corners of the lower die. The upper guide assemblies 30a cooperate with the opposing lower guide assemblies 30b to prevent misalignment between the upper and lower dies, which would affect the punching accuracy. The upper limit post 40a cooperates with the opposite lower limit post 40b to control the depth of punching.

[0047] The working process of this composite processing mold is as follows: Please refer to Figure 8 The feeder feeds the material strip 50 from the feeding assembly 20 into the mold. The guide block 10 guides the material strip 50. The lower lifting block 7 is in the third position, supporting the material strip 50. At this time, the upper mold is in the open state. The pressure plate 3 is locked and suspended on the upper template 4 by the upper limit part 32, located in the first position, protruding from the upper cutting assembly 1. When the punch press is started, the upper die moves downward, and the pressure plate 3 and the lower lifting block 7 cooperate to press the material strip 50. The upper die continues to move downward, the upper spring 31 and the lower spring 71 are compressed, the pressure plate 3 moves to the second position, and the lower lifting block 7 moves to the fourth position. Then, the upper cutting blade assembly 1 and the upper scrap blade 91 cooperate with the concave module 2 and the lower scrap blade 92 to punch and cut the inner and outer ring scrap until the upper limit post 40a and the lower limit post 40b contact, the scrap is completely cut off, the inner ring scrap (i.e. the scrap generated by the punching cutter 11) falls into the scrap box 94, and the outer ring scrap (i.e. the scrap generated by the dropping cutter 12) slides into the scrap bin through the scrap chute 93. The upper die moves upward and resets, the upper spring 31 rebounds, and the pressure plate 3 resets from the second position to the first position; the lower lifting block 7 lifts the material sheet upward and then resets to the third position, where it stops moving upward due to the lower limit piece 72. After the operator manually removes the material sheet, the feeder continues to feed material, preparing for the next punching.

[0048] In summary, the composite processing mold provided by this utility model completes blanking and punching in a single punching operation, overcoming the shortcomings of traditional multi-mold and multi-step processing, such as time-consuming, high-cost, and low-precision processes. The cooperation of the upper scrap cutter 91, lower scrap cutter 92, scrap box 94, and scrap chute 93 achieves automatic segmentation and collection of scrap, eliminating the need for machine downtime for scrap cleaning. The mutual pressing structure between the pressure plate 3 and the lower lifting block 7 ensures the tight fixation of the strip 50, effectively preventing its displacement. The combination of the upper limit member 32 and the upper spring 31 enables the automatic rebound of the pressure plate 3, while the combination of the lower limit member 72 and the lower spring 71 enables the lower lifting block 7 to automatically lift the strip. The structure is simple and the cost is low.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
