Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, the utility model relates to a novel stamping die for high-fin aluminum profiles. Background Art

[0002] High-fin aluminum profiles are widely used in the heat dissipation industry. However, due to the relatively high fins, most of them are processed by first sawing with a saw and then punching and drilling, etc., resulting in relatively low production efficiency. And ordinary stamping methods will cause problems such as fin deformation and rough cross-sections. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a novel stamping die for high-fin aluminum profiles, which has the advantages of high production efficiency and avoiding the occurrence of fin deformation and rough cross-sections.

[0004] To achieve the above object, the utility model provides the following technical solution: A novel stamping die for high-fin aluminum profiles, including an upper die assembly, a lower die assembly and a product. An upper die cutting insert is fixedly installed at the bottom end of the upper die assembly. An inclined punch is fixedly installed in the middle of the upper die cutting insert. An upper die punching insert is fixedly installed at the bottom end of the upper die assembly. A fitting groove is opened at the bottom end of the upper die cutting insert. A positioning block is fixedly installed at the top end of the lower die assembly. A punching head is fixedly installed in the middle of the upper die punching insert. A limiting block is fixedly installed at the right end of the lower die assembly.

[0005] As a preferred technical solution of the utility model, a rotating shaft is fixedly installed on the right side of the limiting block. A connecting rod is rotatably connected to the surface of the rotating shaft. A rotating block is fixedly installed at the right end of the connecting rod. A spring is fixedly installed in the middle of the limiting block. A connecting plate is fixedly installed at the right end of the spring. A connecting rope is fixedly installed at the right end of the connecting plate.

[0006] As a preferred technical solution of the utility model, the lower die assembly is located below the upper die assembly, and the cross-sectional shape of the product is the same as the cross-sectional shape of the fitting groove.

[0007] As a preferred technical solution of the utility model, the product is placed on the lower die assembly, and the positioning blocks are located on the front and rear sides of the product.

[0008] As a preferred technical solution of the utility model, the front and rear sides of the bottom end of the inclined punch are inclined surfaces, and the angles between the inclined surfaces on the front and rear sides of the bottom end of the inclined punch and the horizontal plane are both 45 degrees.

[0009] As a preferred technical solution of the utility model, the right end of the connecting rope penetrates to the right side of the limiting block, and the connecting rope is fixedly connected to the rotating block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. By setting an inclined punch in the present utility model, since the bottom end of the inclined punch consists of two 45-degree side edges, during the downward movement of the upper die assembly, the straight downward pressure of stamping is cleverly converted into a lateral force at an inclined 45-degree angle. In cooperation with the upper die punching and cutting insert inserted into the product for support, a smooth and flat product can be punched out, avoiding the deformation of the fins of the product and the rough cross-section. Moreover, by setting an upper die punching insert on the left side of the inclined punch, punching and cutting can be integrated, and the production efficiency can be increased by about 50%.

[0012] 2. By setting a rotatable rotating block on the right side of the limit block in the present utility model, when the product needs to be taken out, the product is directly rotated to the right, and the product is pushed to rotate the rotating block to open the rotating block. After taking out, due to the setting of the spring, the rotating block can be pulled back under the elastic action of the spring, thereby limiting the next product, realizing the rapid blanking of the product.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 10 shown, the present invention provides a novel high-fin aluminum profile stamping die, including an upper die assembly 1, a lower die assembly 2 and a product 7. A upper die punching and cutting insert 3 is fixedly installed at the bottom end of the upper die assembly 1. An inclined punch 4 is fixedly installed in the middle of the upper die punching and cutting insert 3. A upper die punching insert 5 is fixedly installed at the bottom end of the upper die assembly 1. A fitting groove 8 is opened at the bottom end of the upper die punching and cutting insert 3. A positioning block 9 is fixedly installed at the top end of the lower die assembly 2. A punching head is fixedly installed in the middle of the upper die punching insert 5. A limit block 6 is fixedly installed at the right end of the lower die assembly 2;

[0026] By setting the inclined punch 4, since the bottom end of the inclined punch 4 is composed of two 45-degree side edges, during the downward movement of the upper die assembly 1, the straight downward pressure of stamping is cleverly converted into a lateral force inclined at an angle of 45 degrees, and it is supported by inserting the upper die punching and cutting insert 3 into the product 7, so as to realize punching out a smooth and flat product 7, avoiding the deformation of the fins of the product 7 and the roughness of the cross section. And by setting the upper die punching insert 5 on the left side of the inclined punch 4, punching and cutting integration can be realized, and the production efficiency is increased by about 50%.

[0027] Among them, a rotating shaft 12 is fixedly installed on the right side of the limit block 6. A connecting rod 11 is rotatably connected to the surface of the rotating shaft 12. A rotating block 10 is fixedly installed at the right end of the connecting rod 11. A spring 13 is fixedly installed in the middle of the limit block 6. A connecting plate 14 is fixedly installed at the right end of the spring 13. A connecting rope 15 is fixedly installed at the right end of the connecting plate 14;

[0028] By arranging a rotatable rotating block 10 on the right side of the limit block 6, when it is necessary to take out the product 7, the product 7 is directly rotated to the right, and the product 7 pushes the rotating block 10 to rotate, so as to open the rotating block 10. After taking out, due to the arrangement of the spring 13, the rotating block 10 can be pulled back under the elastic action of the spring 13, thereby limiting the next product 7, realizing the rapid blanking of the product 7.

[0029] Among them, the lower die assembly 2 is located below the upper die assembly 1, and the cross-sectional shape of the product 7 is the same as that of the fitting groove 8;

[0030] The fitting groove 8 is arranged to be completely adapted to the product 7. When the upper die punching insert 3 moves downward, the product 7 can be completely embedded in the fitting groove 8, thereby filling the gaps on both sides of the cutting area of the product 7 and avoiding the situation of fin skew of the product 7.

[0031] Among them, the product 7 is placed on the lower die assembly 2, and the positioning blocks 9 are located on the front and back sides of the product 7;

[0032] The raw material of the product 7 is placed on the lower die assembly 2 and in the middle of the positioning block 9. Subsequently, when the upper die assembly 1 moves downward, it drives the upper die punching insert 5 and the upper die cutting insert 3 to move downward. The upper die punching insert 5 and the upper die cutting insert 3 first move downward and insert between the fins of the product 7. Subsequently, the upper die assembly 1 continues to move downward. The punching head in the upper die punching insert 5 punches the product 7 on the left side, while the inclined surface punch 4 cuts the product 7 on the right side. The positioning block 9 is arranged to limit the position of the product 7, avoiding the situation of punching and punching failure caused by the placement deviation of the product 7.

[0033] Among them, the front and back sides of the bottom end of the inclined surface punch 4 are inclined surfaces, and the angles between the inclined surfaces on the front and back sides of the bottom end of the inclined surface punch 4 and the horizontal plane are both 45 degrees;

[0034] Since the bottom end of the inclined surface punch 4 is composed of two 45-degree side edges, during the downward movement of the upper die assembly 1, the straight downward pressure of stamping is cleverly converted into a lateral force inclined at 45 degrees, realizing a smooth and flat cross-section.

[0035] Among them, the right end of the connecting rope 15 penetrates to the right side of the limit block 6, and the connecting rope 15 is fixedly connected to the rotating block 10;

[0036] The connecting plate 14 and the connecting rope 15 are connected by the spring 13. When the rotating block 10 loses the push of the product 7, the stretched spring 13 pulls the connecting plate 14 and the connecting rope 15 back through elasticity, thereby driving the reset of the rotating block 10. And due to the elasticity of the rotating block 10, when the product 7 is moved, the situation that the product 7 immediately pushes the rotating block 10 to rotate when contacting the rotating block 10 can also be avoided.

[0037] Working principle and usage process of the utility model:

[0038] During use, place the raw material of product 7 on the lower die assembly 2 and in the middle of the positioning block 9. Subsequently, when the upper die assembly 1 moves downward, it drives the upper die punching insert 5 and the upper die cutting insert 3 to move downward. The upper die punching insert 5 and the upper die cutting insert 3 first move downward and insert between the fins of product 7. Then, the upper die assembly 1 continues to move downward. The punching head in the upper die punching insert 5 performs a punching operation on the left-side product 7, while the inclined punch 4 performs a cutting operation on the right-side product 7. Since the bottom end of the inclined punch 4 consists of two 45-degree sides, during the downward movement of the upper die assembly 1, the straight downward pressure of stamping is cleverly converted into a lateral force inclined at a 45-degree angle. With the cooperation of the upper die cutting insert 3 inserted into product 7 for support, a smooth and flat product 7 is punched out. After stamping, the upper die assembly 1 moves upward. Directly pulling out the product 7 after the right-side cutting horizontally to the right can drive the rotating block 10 to rotate to the right, thereby taking out the punched product 7. Subsequently, under the action of the elastic force of the spring 13, the rotating block 10 is pulled back by the connecting rope 15, thereby realizing the reset of the rotating block 10 and limiting the next product 7 to be punched.

[0039] It should be noted that in this text, relative terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
