[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Please see Figure 1-6 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0059] This invention provides a wire-cutting structure applicable to wire cutting scenarios. This wire-cutting structure can cut copper wire as well as wires of other materials. In one application scenario, the wire-cutting structure can be installed on a wire forming machine to precisely cut the wire output from the machine. Precise cutting improves the accuracy and efficiency of wire cutting, while also improving wire quality and reducing wire loss. The invention will now be described in detail through specific embodiments.

[0060] Please see Figure 1 As shown, Figure 1A wire-cutting structure provided in this embodiment of the invention may include a limiting cover 10, a main cutting blade 20, a secondary cutting blade 30, a crankshaft 40, a main cutting blade cam 50, and a secondary cutting blade cam 60. The limiting cover 10 may be disposed at the wire outlet end of a wire forming machine. The main cutting blade 20 and the secondary cutting blade 30 are slidably disposed within the limiting cover 10. Therefore, the main cutting blade 20 and the secondary cutting blade 30 are both limited by the inner wall of the limiting cover 10, ensuring alignment between them. When the main cutting blade 20 moves downward and the secondary cutting blade 30 moves upward simultaneously, the wire can be cut. The crankshaft 40 may pass through the limiting cover 10, and the main cutting blade cam 50 and the secondary cutting blade cam 60 may be installed in the portion of the crankshaft 40 located inside the limiting cover 10. When the crankshaft 40 rotates, it drives the main cutting cam 50 and the secondary cutting cam 60 to move vertically in opposite directions. The main cutting cam 50 can be connected to the main cutting section 20 to drive the main cutting section 20 to move. The secondary cutting cam 60 can be connected to the secondary cutting section 30 to drive the secondary cutting section 30 to move. When this wire cutting structure cuts wire, the wire output from the wire forming machine can pass between the blades of the main cutting section 20 and the secondary cutting section 30. At this time, the crankshaft 40 can be driven to rotate, which drives the main cutting cam 50 to move downward and simultaneously drives the secondary cutting cam 60 to move upward. This drives the main cutting section 20 to move downward and simultaneously drives the secondary cutting section 30 to move upward, thereby accurately cutting the wire between the blades. Precise cutting improves the accuracy of wire cutting and reduces the occurrence of incomplete wire cutting, thus improving the efficiency of wire cutting. At the same time, when the incidence of incomplete wire breakage decreases, the quality of the wire can be improved, and the wire loss can be reduced accordingly.

[0061] Please see Figure 1 As shown, in one embodiment of the present invention, one end of the limiting cover 10 may be provided with an opening so that the main cutting blade 20 and the auxiliary cutting blade 30 can extend out of the opening. The portions of the main cutting blade 20 and the auxiliary cutting blade 30 extending out of the opening can cut the wire. The limiting cover 10 may be provided with connecting holes on both sides so that the crankshaft 40 can rotate within the connecting holes, and the diameter of the connecting holes can be set according to the diameter of the crankshaft 40.

[0062] Please see Figure 1 As shown, in one embodiment of the present invention, the main cutting blade section 20 may include a main cutting blade fixing block 21 and a main cutting blade 22. The main cutting blade fixing block 21 is slidable within the limiting cover 10, and the main cutting blade 22 is disposed at the portion of the main cutting blade fixing block 21 that extends out of the limiting cover 10. The main cutting blade 22 can be connected to the main cutting blade fixing block 21 via a connector. When the main cutting blade 22 is worn, the connector can be removed, and the main cutting blade 22 can be removed from the main cutting blade fixing block 21 for replacement.

[0063] Please see Figure 1As shown, in one embodiment of the present invention, the secondary cutter portion 30 may include a secondary cutter fixing block 31 and a secondary cutter 32. The secondary cutter fixing block 31 is slidable within the limiting cover 10, and the secondary cutter 32 is disposed at the portion of the secondary cutter fixing block 31 that extends out of the limiting cover 10. The secondary cutter 32 can be connected to the secondary cutter fixing block 31 via a connector. When the secondary cutter 32 wears, the connector can be removed, and the secondary cutter 32 can be removed from the secondary cutter fixing block 31 for replacement.

[0064] Please see Figure 6 As shown, in one embodiment of the present invention, the shape of the main cutter 22 is not limited and can be sheet-shaped, arc-shaped, conical, or other shapes. The shape of the secondary cutter 32 is also not limited and can be sheet-shaped, arc-shaped, conical, or other shapes. As long as the blade edges of the main cutter 22 and the secondary cutter 32 are matched, the wire can be cut.

[0065] Please see Figure 1 As shown, in one embodiment of the present invention, the opening size of the limiting cover 10 can be set according to actual needs. Specifically, the length of the opening of the limiting cover 10 can be set as L1, the maximum width of the main cutter fixing block 21 can be set as D1, and the maximum width of the secondary cutter fixing block 31 can be set as D2. Then, L1, D1, and D2 satisfy the following condition: L1 = D1 = D2. The main cutter fixing block 21 and the secondary cutter fixing block 31 can be relatively fitted together. The maximum thickness of the overall structure formed by the main cutter fixing block 21 and the secondary cutter fixing block 31 can be set as D3, and the width of the opening of the limiting cover 10 can be set as L2. Then, L2 and D3 satisfy the following condition: L2 = D3. It can be seen that the opposing surfaces of the main cutter fixing block 21 and the secondary cutter fixing block 31 are fitted against the inner wall of the limiting cover 10 so that the main cutter fixing block 21 and the secondary cutter fixing block 31 are stably limited, and the main cutter 22 can be aligned with the secondary cutter 32. When the main cutter fixing block 21 and the secondary cutter fixing block 31 move relative to each other, the main cutter 22 and the secondary cutter 32 can be driven to precisely cut the wire.

[0066] Please see Figure 5 As shown, in one embodiment of the present invention, the crankshaft 40 may include a main shaft 41, a main cam connecting shaft 42, and a secondary cam connecting shaft 43. The main shaft 41 may be connected to the output shaft of the drive member 70, the main cam connecting shaft 42 may be fixed to one end of the main shaft 41, and the secondary cam connecting shaft 43 may be connected to the main cam connecting shaft 42. When the main shaft 41 is driven to rotate, it can drive the main cam connecting shaft 42 to rotate, thereby driving the secondary cam connecting shaft 43 to rotate synchronously. The central axes of the main shaft 41, the main cam connecting shaft 42, and the secondary cam connecting shaft 43 are parallel, and the central axes of the main shaft 41, the main cam connecting shaft 42, and the secondary cam connecting shaft 43 are located on different planes. This is so that when the crankshaft 40 rotates, it can drive the main cam connecting shaft 42 and the secondary cam connecting shaft 43 to move in opposite directions.

[0067] Please see Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the main cutter cam 50 can be mounted on the main cam connecting shaft 42. The main cutter cam 50 has a through hole for the main cam connecting shaft 42 to pass through, and the main cam connecting shaft 42 can rotatably rotate within the through hole of the main cutter cam 50. During shearing, the main shaft 41 can start to rotate, and the main cam connecting shaft 42 can rotate around the central axis of the main shaft 41 accordingly. Consequently, one end of the main cutter cam 50 can synchronously rotate around the main cam connecting shaft 42. Simultaneously, the other end of the main cutter cam 50 rotates around the main cutter fixing block 21, causing the main cutter fixing block 21 to move downwards, thus causing the main cutter 22 to move downwards. The secondary cutter cam 60 can be mounted on the secondary cam connecting shaft 43. The secondary cutter cam 60 has a through hole for the secondary cam connecting shaft 43 to pass through, and the secondary cam connecting shaft 43 can rotatably rotate within the through hole of the secondary cutter cam 60. During shearing, the main shaft 41 can begin to rotate, causing the secondary cam connecting shaft 43 to rotate around the central axis of the main shaft 41. Consequently, one end of the secondary cutter cam 60 can simultaneously rotate around the secondary cam connecting shaft 43. At the same time, the other end of the secondary cutter cam 60 rotates around the secondary cutter fixing block 31, causing the secondary cutter fixing block 31 to move upward, thus causing the secondary cutter 32 to move upward. As can be seen from the above, the rotation of the crankshaft 40 can cause the main cutter cam 50 to move downward, and simultaneously cause the secondary cutter cam 60 to move upward. This causes the main cutter 22 to move downward, and simultaneously causes the secondary cutter 32 to move upward, for shearing.

[0068] Please see Figure 4 As shown, in one embodiment of the present invention, after one shearing operation, the main cutter 22 and the secondary cutter 32 move away from each other to prepare for the next shearing operation. Specifically, after one shearing operation, the main shaft 41 rotates in the opposite direction to the shearing operation. The main cam connecting shaft 42 can rotate around the central axis of the main shaft 41, and one end of the main cutter cam 50 can rotate synchronously around the main cam connecting shaft 42. At the same time, the other end of the main cutter cam 50 rotates around the main cutter fixing block 21, causing the main cutter fixing block 21 to move upward, thus causing the main cutter 22 to move upward. Simultaneously, the secondary cam connecting shaft 43 rotates around the central axis of the main shaft 41, and one end of the secondary cutter cam 60 can rotate synchronously around the secondary cam connecting shaft 43. The other end of the secondary cutter cam 60 can rotate around the secondary cutter fixing block 31, causing the secondary cutter fixing block 31 to move downward, thus causing the secondary cutter 32 to move downward. This is to make the main cutter 22 and the secondary cutter 32 move away from each other.

[0069] Please see Figure 1 As shown, Figure 1A wire cutting device provided in this embodiment of the invention may include a wire cutting structure, a driving member 70, and a connecting seat 80. The wire cutting structure may be installed on one side of the connecting seat 80, and the driving member 70 may be installed on the other side of the connecting seat 80. The output end of the driving member 70 may pass through the connecting seat 80 and connect to the wire cutting structure to drive the wire cutting structure to cut the wire. When the connecting seat 80 is installed at the wire outlet of the wire forming machine, the relative position between the wire cutting structure and the wire outlet of the wire forming machine can be determined. This ensures that the output wire can be accurately fed between the main cutter 22 and the auxiliary cutter 32 of the wire cutting structure, improving the alignment between the wire and the cutters.

[0070] Please see Figure 2 As shown, in one embodiment of the present invention, the output shaft of the drive member 70 is connected to the main shaft 41 of the wire-cutting structure to drive the main shaft 41 to rotate. The structure of the drive member 70 is not limited and can be a motor drive, gear drive, or other drive structures. Taking a motor as an example, the output shaft of the motor can be connected to the main shaft 41, and when the motor is running, its output shaft can drive the main shaft 41 to rotate.

[0071] Please see Figure 1 As shown, in one embodiment of the present invention, the specific structure of the connector 80 is not limited; its cross-section can be square, circular, or other shapes, and can be set according to actual connection requirements. The connector 80 may be provided with connecting holes, and the number of connecting holes is not limited; it can be one, two, or other numbers. Similarly, the wire outlet end of the wire forming machine may be provided with matching holes, and the number of matching holes is not limited; it can be one, two, or other numbers. When installing the connector 80, a connector can be used to pass through the connecting holes and matching holes for connection, so that the connector 80 can be installed on the wire outlet end of the wire forming machine.

[0072] In summary, the wire cutting structure and device provided by this invention can improve the accuracy and efficiency of wire cutting, improve the quality of the wire, and reduce wire loss.
