For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] Such as Figures 1-6As shown in the figure, a curved twill cutter roller assembly includes a cutter roller and a shaft body. The cutter roller includes a first cutter roller 1 and a second cutter roller 2. A number of convex teeth 5 are provided on the sides of the first cutter roller 1 and the second cutter roller 2. A tooth groove 6 is formed between two adjacent convex teeth 5 on the same cutter roller. A number of curved twill protrusions 7 are provided on the two sides of the convex tooth 5. A curved twill groove 8 is formed between two adjacent curved twill protrusions 7. The orientations of a number of curved twill protrusions 7 on the same side of the convex tooth 5 are the same.

[0031] In the present utility model, the first cutter roller 1 and the second cutter roller 2 rotate and mesh to integrally process materials to form fins. Compared with the traditional single-piece stamping forming, the cutter roller of the present utility model can make the production efficiency of the fins higher, the forming speed faster, and it is integrally processed, not easy to wear and break the tool, and has a longer service life. In addition, the twill protrusions on the convex teeth 5 of the cutter roller of the present utility model are curved. The fins formed by the cutter roller assembly of the present utility model are rectangular oblique curved convex and concave fins, and both sides are bulged, so that the contact surface between the fins and the ambient air is larger, the welding rate is high, and the heat dissipation performance is high.

[0032] As Figure 2 shown, the shape of the cutter roller is gear-shaped, and curved twill protrusions 7 are provided on both sides of the convex tooth 5 of the cutter roller.

[0033] Specifically, the fin material can be aluminum foil, and it is processed and formed into aluminum foil fins by the curved twill cutter roller assembly of the present utility model.

[0034] In the present utility model, a number of twill protrusions are provided on the two sides of the convex tooth 5 of the cutter roller. After the aluminum foil is roll-formed, as Figure 7 and Figure 8 shown, bulges will appear on both sides (both sides) of the formed fins, that is, protrusions and depressions corresponding to the twill protrusions will be formed on both sides of the processed twill fins. The bulges (or protrusions and depressions) increase the contact heat dissipation area between the fins and the environment, thereby improving the heat dissipation performance of the radiator. And the twill protrusions of the present application are curved. Compared with the straight twill protrusions, the formed bulged surface area is larger, further increasing the contact heat dissipation area between the fins and the ambient air and improving the heat dissipation performance.

[0035] As Figure 1 shown, further, the shaft body includes a first shaft body 3 and a second shaft body 4. The first shaft body 3 is connected to the first cutter roller 1, and the second shaft body 4 is connected to the second cutter roller 2.

When the first shaft body 3 is assembled with the first cutter roller 1, one end of the first tool mounting shaft 9 is inserted into the first shaft hole 13 of the first cutter roller 1.

[0038] Further, the second shaft body 4 includes a second tool mounting shaft 11 and a second transmission gear 12. The second tool mounting shaft 11 penetrates through the second transmission gear 12. A second shaft hole 14 penetrating through the second cutter roller 2 is provided at the middle position of the second cutter roller 2. When the second shaft body 4 is assembled with the second cutter roller 2, one end of the second tool mounting shaft 11 is inserted into the second shaft hole 14 of the second cutter roller 2.

[0039] As Figure 1 shown, the first transmission gear 10 has the same diameter as the first cutter roller 1, and the second transmission gear 12 has the same diameter as the second cutter roller 2. During assembly, the first transmission gear 10 meshes with the second transmission gear 12.

[0040] Further, the two side surfaces of the convex tooth 5 are respectively a first side surface and a second side surface. The curved diagonal rib protrusions 7 on the first side surface are symmetrical to the curved diagonal rib protrusions 7 on the second side surface.

[0041] As another implementation manner, the curved diagonal rib protrusions 7 on the first side surface and the curved diagonal rib protrusions 7 on the second side surface may not be symmetrical to each other, and the curved diagonal rib protrusions 7 on the first side surface and the curved diagonal rib protrusions 7 on the second side surface may be staggered forward or backward by a certain distance from each other.

[0042] As Figure 4 shown, the shape of the curved diagonal rib protrusion 7 is similar to a streamline shape or an elongated S shape.

[0043] Further, the convex teeth 5 on the first cutter roller 1 can exactly mesh with the tooth grooves 6 on the second cutter roller 2, and the convex teeth 5 on the second cutter roller 2 can exactly mesh with the tooth grooves 6 on the first cutter roller 1.

[0044] Further, the curved diagonal rib protrusions 7 on both sides of the convex teeth 5 on the first cutter roller 1 can exactly mesh with the curved diagonal rib grooves 8 on both sides of the convex teeth 5 on the second cutter roller 2, and the curved diagonal rib protrusions 7 on both sides of the convex teeth 5 on the second cutter roller 2 can exactly mesh with the curved diagonal rib grooves 8 on both sides of the convex teeth 5 on the first cutter roller 1.

[0045] As Figure 4 shown, as an implementation manner, there are 6 curved diagonal rib protrusions 7 on one side of the convex tooth 5. Taking the protrusion extending from the top end to the bottom end of the side surface of the convex tooth 5 as a complete curved diagonal rib protrusion 7, there are 4 complete curved diagonal rib protrusions 7 and 2 incomplete curved diagonal rib protrusions 7.

[0046] As an implementation manner, there may be 8 curve twill protrusions 7 on one side of the convex tooth 5. Taking the protrusion extending from the top end to the bottom end of the side surface of the convex tooth 5 as a complete curve twill protrusion 7, there are 6 complete curve twill protrusions 7 and 2 incomplete curve twill protrusions 7.

[0047] As an implementation manner, there may be 5 curve twill protrusions 7 on one side of the convex tooth 5. Taking the protrusion extending from the top end to the bottom end of the side surface of the convex tooth 5 as a complete curve twill protrusion 7, there are 3 complete curve twill protrusions 7 and 2 incomplete curve twill protrusions 7.

[0048] That is to say, the number of curve twill protrusions 7 on the side surface of the convex tooth 5 is not fixed and can be selectively set according to the width of the curve twill protrusion 7, the inclination angle, and the length of the convex tooth 5 (the width of the cutter roller). Any number of curve twill protrusions 7 that can achieve a larger bulging surface area of the fin by arranging the curve twill protrusions 7 on the side surface of the convex tooth 5, further increasing the contact heat dissipation area between the fin and the ambient air, and improving the heat dissipation performance is within the protection scope of the present utility model.

[0049] Such as Figure 6 shown, further, the top end 15 of the convex tooth is a concave smooth curved surface, and the bottom surface 16 of the tooth groove is a convex smooth curved surface.

[0050] When the first cutter roller 1 and the second cutter roller 2 rotate and mesh, the top end 15 of the convex tooth of one cutter roller just cooperates with the bottom surface 16 of the tooth groove of the other cutter roller.

[0051] Further, a plurality of process holes 17 are provided on both the first cutter roller 1 and the second cutter roller 2, and the process holes 17 penetrate through the first cutter roller 1 and the second cutter roller 2 along the axial direction.

[0052] As an implementation manner, such as Figure 2 and Figure 5 shown, there are 2 process holes 17 on the first cutter roller 1 and the second cutter roller 2, and the 2 process holes 17 are arranged oppositely on the first cutter roller 1 and the second cutter roller 2.

[0053] As an implementation manner, the number of process holes 17 on the first cutter roller 1 and the second cutter roller 2 may also be 3, and the 3 process holes 17 are evenly distributed on the first cutter roller 1 and the second cutter roller 2.

[0054] As an implementation manner, the number of process holes 17 on the first cutter roller 1 and the second cutter roller 2 may also be 4, and the 4 process holes 17 are evenly distributed on the first cutter roller 1 and the second cutter roller 2.

[0055] That is to say, the present utility model does not specifically limit the number of process holes 17, and the number of process holes 17 can be selectively set according to factors such as the size and material of the cutter roller.

[0056] The process holes 17 can maintain the original shape of the parts after the casting and cooling of the cutter roller, block the generation of internal stress, improve the stress distribution state after the quenching of the cutter roller, make the deformation value of the cutter roller after the heat treatment of the workpiece reach the lowest value. At the same time, the process holes 17 can play a role of a center point to help the accurate positioning of the parts. When measuring or assembling the cutter roller, it can improve the efficiency of the process operation and ensure the assembly accuracy.

[0057] Furthermore, process holes 17 are also provided on the transmission gears of the shaft body. The number and position distribution of the process holes 17 on the transmission gears correspond to the number and position distribution of the process holes 17 on the cutter roller.

[0058] Furthermore, as Figure 5 shown, rectangular clamping grooves 18 are provided on the inner surfaces of the first shaft hole 13 and the second shaft hole 14.

[0059] The rectangular clamping grooves 18 play a role of limiting and preventing the relative sliding between the cutter roller and the shaft body. A rectangular convex block matching with the rectangular clamping groove 18 is provided on the tool mounting shaft of the shaft body, and the rectangular convex block can just be embedded into the rectangular clamping groove 18.

[0060] The working principle of the curve twill cutter roller of the present utility model: Assemble the first cutter roller 1, the second cutter roller 2, the first shaft body 3, and the second shaft body 4. The convex teeth 5 and the tooth grooves 6 of the first cutter roller 11 and the second cutter roller 2 are meshed relatively, the first transmission gear 10 and the second transmission gear 12 are meshed with each other, and the first shaft body 3 and the second shaft body 4 are driven to rotate through the motor transmission, so as to drive the first cutter roller 1 and the second cutter roller 2 to rotate, and the fins are roll-formed.

[0061] The formed fins are as Figure 7 and Figure 8 shown. Different from the processing methods of the traditional louver fins and convex-concave fins, the forming molds of the traditional louver fins and convex-concave fins are processed by single pieces and finally spliced and assembled for rolling. The curve twill fins processed by the curve twill cutter roller assembly of the present utility model are integrally processed and formed. After forming, they are not easy to wear, are strong and durable, are suitable for relatively harsh environments, and are convenient to clean. And the formed fins are rectangular oblique curve convex-concave fins, as Figure 8 shown, with double-sided bulging, as Figure 7 shown, making the contact surface between the fins and the air larger, with a high welding rate and high heat dissipation performance.
